In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides a vehicle self-generating device, including a synchronizing wheel 10, a rotating shaft 20, a driving wheel 30, a generator 40, and a transmission member 50, where the synchronizing wheel 10 is used to be fixedly connected to a rotating part 91 of a vehicle, the rotating shaft 20 is used to be rotatably connected to a fixed part 92 of the vehicle, the driving wheel 30 is sleeved on the rotating shaft 20 and is fixedly connected to the rotating shaft 20, the synchronizing wheel 10 is in transmission connection with the driving wheel 30 through the transmission member 50, a width of the driving wheel 30 along an axial direction thereof is greater than a width of the synchronizing wheel 10, and an input shaft of the generator 40 is fixedly connected to one end of the rotating shaft 20.

When the rotating part 91 of the vehicle rotates, the synchronizing wheel 10 rotates synchronously therewith, the driving wheel 30 is driven to rotate by the transmission member 50, the driving wheel 30 drives the rotating shaft 20 fixedly connected therewith to rotate, and the rotating shaft 20 drives the generator 40 fixedly connected therewith to rotate, so that the kinetic energy of the vehicle is converted into electric energy. Because the synchronizing wheel 10 can deviate in the process that the rotating part 91 of the vehicle drives the synchronizing wheel 10 to rotate, the transmission part 50 at one end of the synchronizing wheel 10 also synchronously deviates, the transmission wheel 30 is fixedly connected with the rotating shaft 20, the transmission part 50 at one end of the transmission wheel 30 cannot deviate along with the transmission wheel 30, the width of the transmission wheel 30 in the axial direction is set to be larger than that of the synchronizing wheel 10 in the axial direction, so that the transmission part 50 at one end of the transmission wheel 30 can deviate in a certain range in the axial direction of the transmission wheel 30, the transmission part 50 is prevented from falling off from the transmission wheel 30, the abrasion of the transmission part 50 and the transmission wheel 30 is reduced, the service lives of the transmission part 50 and the transmission wheel 30 are prolonged, and the self-generating equipment of the vehicle has better durability.

Optionally, the connection mode of the synchronous wheel 10 and the vehicle is not limited, and only the synchronous wheel 10 and the rotating part 91 of the vehicle are ensured to be linked. In one embodiment, the synchronizer 10 is fitted over the wheel axle of the vehicle. The synchronizing wheel 10 is fitted around the middle of the wheel axle at the bottom of the vehicle. Through connecting synchronizing wheel 10 with the wheel hub, compare the traditional mode and need not to reform transform the axletree axle head of vehicle, also can not influence the operation safety of vehicle bearing.

Optionally, the connection mode of the rotating shaft 20 and the driving wheel 30 is not limited, and only needs to be fixedly connected. In one embodiment, the transmission wheel 30 is fixedly connected to the rotating shaft 20 through a shaft key. Specifically, the rotating shaft 20 and the driving wheel 30 may be connected by a spline or a flat key. Specifically, the end of the rotating shaft 20 is fixedly connected to the input shaft of the generator 40 through a coupling.

Referring to fig. 1, 3, 4 and 5, further, the synchronizing wheel 10 and the driving wheel 30 are both gears, the transmission member 50 is a toothed belt, and the extending directions of the gears and the teeth of the toothed belt are the same as the axial direction of the rotating shaft 20. The outer surfaces of the synchronizing wheel 10 and the driving wheel 30 are provided with a plurality of strip-shaped teeth parallel to the rotating shaft 20, wherein the strip-shaped teeth on the driving wheel 30 are longer than the strip-shaped teeth on the synchronizing wheel 10. The inner surface of the toothed belt is correspondingly provided with strip teeth meshed with the strip teeth on the synchronous wheel 10 and the driving wheel 30, and the length of the strip teeth on the toothed belt is slightly shorter than or equal to that of the strip teeth on the synchronous wheel 10. When the synchronizing wheel 10 deviates, the toothed belt is driven to deviate together, and the deviation direction is the same as the extending direction of the strip teeth, so that the toothed belt on the driving wheel 30 can correspondingly deviate along the strip teeth on the driving wheel 30, not only can the deviation be guided, but also the deviation at two ends of the toothed belt is kept balanced, the damage of the toothed belt is further reduced, and the service life of the toothed belt is prolonged.

The toothed belt is limited between the two first flanges 110 and the two second flanges 310, so that the toothed belt is prevented from slipping off the synchronizing wheel 10 and the transmission wheel 30, and the offset of the toothed belt on the transmission wheel 30 is limited.

Further, the width of the transmission wheel 30 is at least 4cm more than the width of the synchronizing wheel 10. It is found through research that when the wheel shaft drives the synchronizing wheel 10 to rotate, the synchronizing wheel 10 inevitably deviates and deviates to about 2cm towards two sides, therefore, the width of the driving wheel 30 is set to be at least 4cm more than the width of the synchronizing wheel 10, so that when the toothed belt is located at the middle position of the driving wheel 30, the two sides have at least 2cm distance to move, which corresponds to the deviation of the synchronizing wheel 10.

In one embodiment, the two ends of the rotating shaft 20 are respectively sleeved with bearings, the bearings are mounted on a bearing frame 70, and the bearing frame 70 is connected with a fixed component 92 of a vehicle. Specifically, the fixed member 92 of the vehicle is a body side member of the vehicle, and the rotating shaft 20 is rotatable relative to the body side member of the vehicle through a bearing and a bearing bracket 70.

Referring to fig. 1 and 3-5, in one embodiment, the vehicular self-generating device further includes an encoder 80, and the encoder 80 is fixedly connected to an end of the rotating shaft 20 far away from the generator 40. Specifically, the encoder 80 is suspended from the bottom of the vehicle and is used to determine the position and mileage of the vehicle. A test system arranged on a vehicle (such as a railway wagon) can position the position of a track fault according to the position information of the vehicle, and can determine when to maintain the vehicle and self-generating equipment of the vehicle according to the running mileage. Specifically, the end of the rotating shaft 20 is fixedly connected to the input shaft of the encoder 80 by another coupling.
