The track gauge is the distance between two tracks, and most countries or regions adopt uniform track gauge, while the track gauge of some countries or regions is different. Before a rail train drives from a track with one track gauge to a track with another track gauge, a rail changing operation is required, namely: the distance between two wheels connected on the same axle in the rail train is adjusted, so that the distance between the wheels can adapt to a new track gauge.

The bottom plate 322 is provided with a long through hole 3221, and the width W1 of the through hole 3221 is smaller than the width W2 of the guide block 42. The guide block 42 is connected to the base plate 41 through a guide rod 45, and the guide block 42 is detachably connected to the guide rod 45. The assembling process of the braking hanging seat 3 and the hanging seat sliding block 4 is as follows: the guide rod 45 penetrates into the guide frame 32 from the outside through the through hole 3221 and then is connected to the guide block 42. The bottom plate 322 acts as a support for the guide block 42 so that the hanger slide 4 and the wheel brake caliper 5 are suspended from the brake hanger 3 and the hanger slide 4 and the wheel brake caliper 5 are able to move in a lateral direction relative to the brake hanger 3.

On the basis of the technical scheme, the bogie can be further optimized.

Fig. 12 is a sectional view of a section B-B in fig. 5, fig. 13 is a sectional view of a section C-C in fig. 5, and fig. 14 is a perspective view of a hanger slider cooperating with an elastic guide mechanism in a bogie provided by an embodiment of the present application. As shown in fig. 12 to 14, an elastic guide mechanism is provided on an inner surface of the top plate 321 of the guide frame 32 facing the bottom plate 322. The top surface of the guide block 42 is recessed inwards to form a wave-shaped guide groove 421 with more than two wave troughs, and the elastic guide mechanism can be abutted against the surface of the wave-shaped guide groove 421.

When the elastic guide means is located close to the valley of the wavy guide groove 421, the lateral movement of the guide block 42 can be restricted in a definite manner. When the rail train vibrates during operation, the guide block 42 may move a small amount in the lateral direction. But the existence of the elastic guide mechanism can prevent the guide block 42 from moving along the transverse direction, thereby ensuring that the hanging seat sliding block 4 is always positioned at the position corresponding to the wheel 21, and achieving the effect of locking the hanging seat sliding block 4.

Specifically, the elastic guide mechanism includes: a first spring 71, a guide roller 72, and a first rotation shaft. One end of the first spring 71 is fixed to the inner surface of the top plate 321 in the brake hanger 3, and the other end is connected to a first rotating shaft, which is inserted into the axial hole of the guide roller 72. The guide roller 72 can rotate around the first rotation shaft, so that the surface of the guide roller 72 and the surface of the wavy guide groove 421 are in rolling friction.

Or, another implementation is: the elastic guide mechanism includes: a first spring 71, a guide roller 72, a first rotating shaft, and a holding block 74. Wherein the top surface of the holder block 74 is depressed inwardly to form a holder groove 741 for accommodating the first spring 71, and the end of the first spring 71 is fixed to the inner surface of the top plate 321. The supporting block 74 is provided with a supporting ear 75 extending toward the guide roller 72, and the supporting ear 75 is provided with a supporting hole 76 through which the end of the first rotating shaft passes. The first shaft is inserted into the axial hole of the guide roller 72.

Further, the brake hanger 3 may be provided with an accommodating groove 33, the first spring 71 may be located in the accommodating groove 33, and an end of the first spring 71 away from the guide roller 72 may be fixed to a bottom surface of the accommodating groove 33. As shown in fig. 8 and 9, a protrusion 34 may be disposed on the top of the top plate 321, and the protrusion 34 is recessed inward toward the surface of the top plate 321 to form the receiving groove 33. The top plate 321 is provided with a through hole corresponding to the notch of the accommodating groove 33, so that the first spring 71 can extend into the accommodating groove 33 through the through hole.

In both of the above solutions, the guide roller 72 is provided to have rolling friction with the wavy guide groove 421, but actually, sliding friction may be used between the elastic guide mechanism and the wavy guide groove 421, that is, the guide roller 72 is not used, but a guide body is connected to one end of the first spring 71 facing the wavy guide groove 421, and a contact surface of the wire body and the wavy guide groove 421 is a cambered surface.

The elastic guide mechanism may be implemented in other ways besides the above three implementations, and this embodiment is not limited in particular.

Fig. 15 is a first cross-sectional view illustrating the movement of the guide block relative to the guide frame in the bogie according to the embodiment of the present invention, fig. 16 is a second cross-sectional view illustrating the movement of the guide block relative to the guide frame in the bogie according to the embodiment of the present invention, fig. 17 is a third cross-sectional view illustrating the movement of the guide block relative to the guide frame in the bogie according to the embodiment of the present invention, and fig. 18 is a fourth cross-sectional view illustrating the movement of the guide block relative to the guide frame in the bogie according to the embodiment of the present invention. In fig. 15 to 18, the wavy guide groove 421 has two troughs and one peak is formed between the two troughs.

The working process of the elastic guide mechanism is as follows:

as shown in fig. 15, the wheel 21 operates in the first position, and accordingly, the current position of the guide block 42 is defined as the initial position, that is: the guide block 42 is located at the rightmost end of the guide frame 32. Under the elastic force of the first spring 71, the guide roller 72 is located in the valley on the left side of the wavy guide groove 421.

As shown in fig. 16, the wheel 21 gradually moves from the first position to the target position, and drives the guide block 42 to move in the same direction through the transmission member 6, specifically: the guide block 42 moves to the left in fig. 16, and the left surface of the crest in the wavy guide groove 421 exerts an upward thrust on the guide roller 72, causing the guide roller 72 to roll on the surface and move upward to apply a pressing force to the first spring 71.

As shown in fig. 17, the guide block 42 continues to move leftward, and the guide roller 72 moves downward by the elastic force of the first spring 71 after passing over the peak in the wavy guide groove 421.

As shown in fig. 18, the pushing force of the wheel 21 on the hanger slider 4 disappears, and the guide roller 72 moves downward under the elastic force of the first spring 71 and pushes the guide block 42 to move leftward until the guide roller 72 is located in the right valley region of the wavy guide groove 421.

When the guide rollers 72 are respectively located in the two wave troughs of the wavy guide groove 421, the guide block 42 can be locked at certain intervals, and the transverse movement of the hanger slide block 4 caused by the vibration of the bogie is avoided.

Preferably, rollers are arranged between the guide frame 32 and the guide block 42 in a transverse direction so that rolling friction is generated between the guide block 42 and the guide frame 32. Specifically, two or more rollers 46 arranged in the lateral direction are provided between the bottom plate 322 and the guide block 42. The roller 46 may be placed directly on the surface of the base plate 322 or an arcuate slot may be provided in the surface of the base plate 322 facing the guide block 42, in which the roller 46 is placed.

On the basis of the above technical solution, the bogie, in particular the transmission 6, can be further optimized.

As shown in fig. 3, 4, 5, 6, 13 and 14, the transmission member 6 includes: and a connecting rod 61, wherein a first end of the connecting rod 61 is used as a first end of the transmission piece 6, and a second end of the connecting rod 61 is used as a second end of the transmission piece 6. The first end of the link 61 extends to the side of the wheel 21. During normal operation of the wheel 21, the first end of the connecting rod 61 is spaced from the wheel 21 by a predetermined distance, and does not contact the wheel 21 and thus does not affect the rotation of the wheel 21.

The second end of the link 61 may be directly connected (e.g., fixedly connected) to the guide block 42 such that when the wheel 21 is moved in the lateral direction into contact with and applies a pushing force to the first end of the link 61, the second end of the link 61 directly carries the guide block 42 in the same direction.

Alternatively, implementations as shown in fig. 3, 4, 5, 6, 13, 14 may also be employed: a hinge is provided on the base plate 41, and a middle portion of the link 61 is hinged to the hinge so that the link 61 can rotate about the hinge. And, when the wheel 21 is moved in the lateral direction to contact and apply a pushing force to the first end of the link 61, the middle portion of the link 61 can bring the guide blocks 42 to move in the same direction.

Further, the hinge support specifically includes: an upper hinge plate 471, a lower hinge plate 472, and a stopper plate 473 connected between the upper hinge plate 471 and the lower hinge plate 472. The upper hinge support plate 471 and the lower hinge support plate 472 are both provided with a hinge hole 474 for connecting with a through hole provided in the middle of the connecting rod 61 through a hinge. The hinge may be a hinged shaft, for example: external threads are formed at two ends of the hinge shaft, and after the hinge shaft is inserted into the through holes in the middle of the upper hinge support plate 471 and the connecting rod 61 and the hinge support hole 474 of the lower hinge support plate 472, the two nuts are respectively screwed with the external threads at the two ends of the hinge shaft from the outside, so that the connecting rod 61 can rotate by taking the hinge shaft as the shaft.

In addition, when the wheel 21 pushes the link 61 to rotate to contact with the stop plate 473, the stop plate 473 restricts the link 61 from further rotating, and the force applied by the link 61 to the stop plate 473 can drive the base plate 41 and the guide block 42 to move towards the same direction as the wheel 21.

Further, the transmission member 6 may further include: and a traverse roller 62 disposed at a first end of the link 61, a tread of the traverse roller 62 being adapted to contact a rim of the wheel 21. Specifically, two engaging lugs 63 are arranged at the first end of the connecting rod 61, through holes are correspondingly formed in the two engaging lugs 63, the rotating shaft penetrates through the through holes of the engaging lugs 63 and the transverse moving roller 62, the transverse moving roller 62 is fixed at the first end of the connecting rod 61, and the transverse moving roller 62 can rotate.

If the distance before the wheel 21 is adjusted while the rail train is stopped, since the wheel 21 is relatively stationary after contacting the connecting rod 61, the traverse roller 62 may not be used. When the distance between the wheels 21 of the rail train is adjusted in the process of running, because the wheels 21 rotate and are in contact with the connecting rods 61 and then move relatively, the transverse moving rollers 62 roll on the side surfaces of the wheels 21, and abrasion caused by long-time friction between only one fixed surface at the end part of each connecting rod 61 and the wheels 21 is avoided.

Further, an adjusting mechanism can be further arranged on the base plate 41, and the adjusting mechanism is arranged between the base plate 41 and the transmission member 6 and used for adjusting the transverse displacement of the transmission member 6, so that a preset distance is kept between the first end of the transmission member 6 and the wheel 21, and the wheel 21 is further ensured not to be contacted with the transmission member 6 in the normal operation process.

As shown in fig. 7, 13 and 14, the adjusting mechanism may specifically include: an adjustment spring 81 and an adjustment block 82. The base plate 41 is provided with an adjustment hole 48 having a center line parallel to the lateral direction, and an adjustment spring 81 is accommodated in the adjustment hole 48. One end of the adjusting spring 81 is fixedly connected with the adjusting block 82, and the adjusting block 82 is abutted against one side of the transmission member 6 facing the guide block 42. The length and the elastic coefficient of the adjustment spring 81 are set according to the distance between the link 61 and the base plate 41 such that the adjustment spring 81 is pressed between the base plate 41 and the adjustment block 82 and abuts between the middle portion and the second end of the link 61.

Preferably, a claw 83 is provided at the end of the adjusting block 82 facing the connecting rod 61, and can be clamped on the connecting rod 61 to prevent the connecting rod 61 from moving in the longitudinal direction and separating from the adjusting block 82, the longitudinal direction refers to the direction perpendicular to the transverse direction, that is: the up-down direction shown in fig. 13. The structure of the latch 83 can be implemented in various ways, and in this embodiment, the latch 83 is two stoppers protruding from the end of the adjusting block 82, and the link 61 can be accommodated between the two stoppers, and the two stoppers limit the movement of the link 61 in the longitudinal direction.

In fig. 13, the left link 61 is pressed leftward by the wheel 21, and the first end of the link 61 is moved leftward and the second end is moved rightward (the link 61 rotates clockwise in the top view of fig. 13). The second end of the link 61 moves rightward, applying a rightward pressure to the regulating spring 81, causing it to compress.

The number of the connecting rods 61 is two, and the two connecting rods are symmetrically distributed on two sides of the guide block 42. The guide block 42 has the same structure as the link 61.

On the basis of the technical scheme, the bogie can be further optimized.

The bogie can also be provided with a locking mechanism, and the locking mechanism is used for locking the guide block 42 at a preset position, so that the transverse movement of the hanger sliding block 4 and the wheel brake clamp 5 under the influence of the vibration of the bogie is further avoided. The preset position is the position of the bogie before the track gauge is changed or the position after the track gauge is changed.

Specifically, as shown in fig. 14, the lock mechanism includes: the locking device comprises a first locking piece 91, a second locking piece 92, a locking block 93 and a second spring 94, wherein a first guide inclined surface 911 is arranged on the first locking piece 91, and a second guide inclined surface 931 matched with the first guide inclined surface 911 is arranged on the locking block 93. As shown in fig. 7 and 14, the guide block 42 has two or more lock grooves 422 arranged in the lateral direction on a side wall parallel to the lateral direction. The second spring 94 has one end connected to the base 31 and the other end connected to the locking block 93 for urging the locking block 93 to be inserted into the locking groove 422 to lock the guide block 42. The first locking member 91 is connected to the second end of the connecting rod 61, so as to cooperate with the second locking member 92 to push the locking block 93 out of the locking groove 422 under the driving of the connecting rod 61, thereby unlocking the guide block 42.

In this embodiment, the number of the locking grooves 422 is two, and the locking block 93 is inserted into the two locking grooves 422 respectively, so that the guide block 42 can be locked at a predetermined position. The two locking grooves 422 are named a first locking groove 4221 and a second locking groove 4222, respectively.

Fig. 19 is a top view, partially in section, of a brake hanger and hanger slide in a truck according to an embodiment of the present application. As shown in fig. 8 and 19, in particular, a receiving groove 311 for receiving the second spring 94 is formed in the base 31, one end of the second spring 94 can be fixed to a bottom surface of the receiving groove 311, and the other end is connected to the locking block 93.

The first locking member 91 and the second locking member 92 may have the structure shown in fig. 14, and be arranged in the lateral direction. The first locking piece 91 and the second locking piece 92 move toward each other and press the locking block 93 to move the locking block 93 in a direction away from the guide block 42, and thereafter, the first locking piece 91 and the second locking piece 92 may be combined to form an approximately rectangular frame shape. Alternatively, the first locking member 91 and the second locking member 92 may have other structures, such as a block structure or a rod structure.

The first locking piece 91 and the second locking piece 92 are connected to the links 61 on the corresponding sides, respectively, for example: a hinged manner may be used. The first locking member 91 and the second locking member 92 are connected to the link 61 in the same direction. Taking the first locking member 91 as an example, specifically, the second end of the connecting rod 61 is provided with a first fixing hole, the end of the first locking member 91 is provided with a second fixing hole, and the center lines of the first fixing hole and the second fixing hole are overlapped. The bolts sequentially penetrate through the first fixing hole and the second fixing hole and are matched and screwed with the nuts, and therefore the first locking piece 91 is connected with the connecting rod 61.

The working process of the locking mechanism is as follows:

first, the wheel 21 moves in the S direction:

fig. 20 is a first schematic structural diagram illustrating the locking mechanism and the guide block in the bogie according to the embodiment of the present application. As shown in fig. 20, the locking block 93 is inserted into the first locking groove 4221 by the elastic force of the second spring 94, and the second guide slope 931 comes into contact with the first guide slope 911. The locking block 93 restricts the guide block 42 from moving in the lateral direction, and achieves the effect of locking the guide block 42.

Fig. 21 is a schematic structural diagram ii illustrating a locking mechanism of a bogie according to an embodiment of the present invention cooperating with a guide block. As shown in fig. 21, when the wheel 21 moves in the S direction, the first end of the link 61 is pushed to move in the same direction, and the second end of the link 61 pushes the first locking member 91 to move in a direction approaching the second locking member 92 (i.e., in a direction opposite to the S direction). After the first locking member 91 moves until the first guide slope 911 contacts the second guide slope 931 of the locking block 93, the first locking member 91 applies a pushing force to the locking block 93 perpendicular to the second guide slope 931, and a component of the pushing force perpendicular to the transverse direction causes the locking member 93 to move in the direction perpendicular to the transverse direction, so that the locking member 93 is disengaged from the first locking groove 4221. And the guide block 42 is moved in the S direction by the link 61, the locking block 93 abuts against the side wall of the guide block 42 between the first locking groove 4221 and the second locking groove 4222 after being disengaged from the first locking member 91 by the elastic force of the second spring 94.

Fig. 22 is a schematic structural diagram three illustrating the locking mechanism and the guide block in the bogie according to the embodiment of the present application. As shown in fig. 22, the guide block 42 continues to move in the S direction, and when the position of the second locking groove 4222 is aligned with the locking block 93, the locking block 93 is inserted into the second locking groove 4222 by the elastic force of the second spring 94 to lock the guide block 42.

In addition, after this step is finished, the link 61 rotates in the original direction until the first end keeps a preset distance from the wheel 21 under the elastic force of the adjusting spring 81.

Second, the wheel 21 moves in the direction opposite to the S direction:

unlike the above process, the first locking member 91 is moved in the S direction by the urging of the link 61, and the second locking member 92 is urged to be released from the locking groove of the locking block 93 by the interaction of the first guide slope 911 and the second guide slope 931 when moved into contact with the locking block 93 and applies pressure to the locking block 93.

The technical scheme can be suitable for the bogie for manual rail transfer and also suitable for the bogie for automatic rail transfer. The manual rail transfer is that the rail train is transferred in a stopped state, and the automatic rail transfer is that the rail train is transferred in a moving process.

The embodiment also provides a railway vehicle which comprises the bogie provided by the embodiment. The bogie can be a power bogie or a non-power bogie.

The rail vehicle provided by the embodiment adopts the bogie, the brake hanging seat is fixed on the framework of the bogie, the hanging seat sliding block is fixedly connected with the wheel brake clamp, the hanging seat sliding block is connected with the brake hanging seat and can move along the transverse direction relative to the brake hanging seat, the transmission part is connected with the hanging seat sliding block, the first end of the transmission part extends to the side surface of the wheel, when the wheel moves along the transverse direction, the transmission piece is pushed by the wheel to drive the hanging seat sliding block and the wheel brake clamp to move along the transverse direction, the wheel braking clamp automatically moves to the position corresponding to the wheel along with the wheel, braking is carried out by matching the wheel with the wheel when the rail train is in a braking state, the position of the wheel braking clamp does not need to be adjusted manually, working strength of operators is reduced, and efficiency of a rail train track gauge changing process is improved.
