Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the related art, a transmission system generally includes an engine, a clutch, and a transmission, the engine, the clutch, and the transmission are connected by a transmission shaft, and torque output from the engine is transmitted to the transmission through the clutch. The shift sequence of the related art Transmission system is generally that when the vehicle recognizes that a shift is required, a TCU (Transmission Control Unit) of the vehicle controls an engine to reduce torque, after the engine reduces to a proper torque, a clutch starts to be disengaged, after the clutch is disengaged, the torque output by the engine cannot be transmitted to a Transmission, then the TCU of the vehicle controls a shift selection executing mechanism to perform operations of gear selection, gear selection and gear engagement, and then the clutch starts to be synchronously engaged, and after the clutch is engaged, the torque output by the engine can be transmitted to the Transmission.

However, during the shifting process, the time for the clutch to be disengaged and engaged is long, so that the power interruption of the vehicle is caused for a long time, and the drivability of the vehicle is affected.

At present, a transmission system on the market generally adopts a motor to control a clutch, and in order to reduce the power interruption time of gear shifting, a small motor which is additionally provided with P3 is generally adopted to maintain the power interruption during gear shifting; and a small motor load is added on an engine belt to accelerate the reduction speed of the engine torque and improve the gear shifting speed.

However, because a small motor is added, a lithium ion battery, a motor controller and the like are required to be added, so that the system cost is greatly increased; the engine is connected with a small motor through a belt to realize the purpose that the engine can rapidly reduce the rotating speed and the torque, and the motor can only act when the clutch is separated, so the improvement effect is not obvious.

In view of this, an embodiment of the present invention provides a transmission system and a vehicle, in which a shift mechanism is disposed between a clutch and a transmission, a first rotating member of the shift mechanism is connected to the clutch, a second rotating member of the shift mechanism is connected to the transmission, when the vehicle needs to shift, a torque of an engine is reduced, at this time, since a rotation speed of the first rotating member is less than a rotation speed of the second rotating member, the first rotating member and the second rotating member are separated from contact with each other, the first rotating member cannot drive the second rotating member to rotate, the torque of the engine stops being transmitted to the transmission, during this process, a driver can perform a shift operation, after the shift is completed, the torque of the engine increases, and since the rotation speed of the first rotating member is greater than the rotation speed of the second rotating member, the first rotating member and the second rotating member are in a contact state, the first rotating member drives the second rotating member to rotate, the torque output by the engine reaches the speed changer; therefore, the process of clutch engagement and disengagement is omitted in the gear shifting process, so that the time of power interruption of the vehicle is shortened, and the drivability of the vehicle is improved.

Example one

Referring to fig. 1, a transmission system disclosed for an embodiment of the present application includes an engine 1, a clutch 2 and a transmission 3, wherein the engine 1 is used for outputting torque, the clutch 2 is used for enabling the engine 1 and the transmission 3 to be connected, and the torque of the engine 1 is transmitted to the transmission 3; or the connection between the engine 1 and the transmission 3 is cut off, and the transmission 3 is prevented from being overloaded when the vehicle is braked emergently; the transmission 3 is used to change the rotation speed and torque from the engine 1 and transmit the torque to wheels of the vehicle.

Referring to fig. 1 and 2, the transmission system further includes a shift mechanism 4, the shift mechanism 4 being located between the clutch 2 and the transmission 3. Specifically, the shift mechanism 4 includes a first rotating member 41 and a second rotating member 42, the first rotating member 41 is fixedly connected to the clutch 2, the second rotating member 42 is fixedly connected to the transmission 3, and in application, the first rotating member 41 and the clutch 2 and the second rotating member 42 and the transmission 3 are connected through transmission shafts.

When the torque of the engine 1 is increased, the first rotating part 41 and the second rotating part 42 are in a contact state, and at the moment, the first rotating part 41 drives the second rotating part 42 to rotate, so that the torque output by the engine 1 is transmitted to the transmission 3; when the torque of the engine 1 is reduced, the first rotating member 41 and the second rotating member 42 are disengaged from each other, and at this time, the first rotating member 41 cannot drive the second rotating member 42 to rotate, so that the torque output by the engine 1 cannot be transmitted to the transmission 3.

Referring to fig. 4, in the vehicle gear shifting process, the TCU of the vehicle controls the engine 1 to reduce the torque, at this time, the first rotating member 41 and the second rotating member 42 are out of contact, the torque output by the engine 1 stops being transmitted to the transmission 3, at this time, the gear shifting, gear selecting and gear shifting can be performed by using the gear shifting executing mechanism of the vehicle, after the gear shifting is completed, the torque of the engine 1 is increased, the first rotating member 41 and the second rotating member 42 are in a contact state again, and the torque output by the engine 1 can be transmitted to the transmission 3; the whole process omits the process of engaging and disengaging the clutch 2, so that the gear shifting can be realized, and the time for interrupting the power of the vehicle is reduced.

In one embodiment, the transmission system further comprises an electric motor and a control module (not shown) for controlling the electric motor to engage or disengage the clutch so that the vehicle can normally perform shifting and braking.

Specifically, when the control module receives a braking signal of the vehicle, the control module controls the motor to disconnect the clutch; when the control module does not receive a braking signal of the vehicle, the control module controls the motor to enable the clutch to keep a joint state, and the torque of the engine is conducted to the gear shifting mechanism through the clutch. And thus, the clutch is not disconnected when the vehicle is shifted, thereby reducing the time for vehicle power interruption.

In a specific application, the Control module may be an ECU (Electronic Control Unit) of the vehicle.

In one embodiment, referring to fig. 1 and 2, the first rotating member 41 and the second rotating member 42 are both annular, and the first rotating member 41 and the second rotating member 42 are overlapped with each other, i.e. the first rotating member 41 and the second rotating member 42 have mutually staggered portions. An engaging structure 43 is disposed between the first rotating member 41 and the second rotating member 42, and the engaging structure 43 is located at a position where the first rotating member 41 and the second rotating member 42 are staggered with each other. The engaging structures 43 are engaged with each other under the condition that the torque of the engine 1 is increased, so that the first rotating member 41 drives the second rotating member 42 to rotate; in case of a torque reduction of the engine 1, the engaging structure 43 is disengaged, and the first rotating member 41 stops rotating the second rotating member 42.

Specifically, referring to fig. 2, the engagement structure 43 includes a first engaging tooth 431 provided on the first rotating member 41 and a second engaging tooth 432 provided on the second rotating member 42, at least one of the first engaging tooth 431 and the second engaging tooth 432 is provided, and the first engaging tooth 431 and the second engaging tooth 432 are fitted to each other.

When the torque of the engine 1 increases, the first engaging tooth 431 will abut against the second engaging tooth 432, so that the first rotating member 41 and the second rotating member 42 cannot rotate relatively, and therefore the first rotating member 41 will drive the second rotating member 42 to rotate; when the torque of the engine 1 is reduced, the first engaging tooth 431 will be disengaged from the second engaging tooth 432, so that the first rotating member 41 and the second rotating member 42 can rotate relatively, and therefore the first rotating member 41 will stop driving the second rotating member 42 to rotate, and the torque output by the engine 1 will stop being transmitted to the transmission 3.

In one embodiment, the first and second catching teeth 431 and 432 may be brought into or out of contact by using a rotation speed relationship between the first and second rotating members 41 and 42.

The main principle is as follows: when the torque of the engine 1 increases, the rotation speed of the first rotating member 41 is greater than that of the second rotating member 42; during the gear shift, when the torque of the engine 1 is reduced, the rotation speed of the first rotating member 41 is rapidly reduced, the second rotating member 42 is connected with the transmission 3, and the transmission 3 is connected with the wheels of the vehicle, because the inertia of the wheels is larger than that of the engine 1, the rotation speed of the second rotating member 42 is reduced slower than that of the first rotating member 41, and the rotation speed of the second rotating member 42 is relatively larger than that of the first rotating member 41.

Specifically, referring to fig. 2, the first engaging tooth 431 is rotatably connected to the first rotating member 41, and the first engaging tooth 431 has a rotation direction as the first direction, and an elastic member (not shown) is disposed between the first engaging tooth 431 and the first rotating member 41, and the elastic member can limit the rotation of the first engaging tooth 431 in a direction opposite to the first direction. In this embodiment, the elastic member may be a torsion spring, and the torsion spring is disposed at a position where the first engaging tooth 431 is rotatably connected, and one end of the torsion spring is connected to the first engaging tooth 431 and the other end is connected to the first rotating member 41. And the first direction is either clockwise or counterclockwise.

In the present embodiment, when the torque of the engine 1 is set to be increased, the rotation direction of the first rotating member 41 is counterclockwise, and the first direction is also counterclockwise.

At this time, when the torque of the engine 1 increases, the rotation speed of the first rotating member 41 is greater than the rotation speed of the second rotating member 42, and when the first rotating member 41 drives the first engaging tooth 431 to contact the second engaging tooth 432, the second engaging tooth 432 contacts with the left side of the first engaging tooth 431, and due to the arrangement of the elastic member, the first engaging tooth 431 cannot rotate clockwise, so that the first engaging tooth 431 and the second engaging tooth 432 are relatively fixed, and the first rotating member 41 can drive the second rotating member 42 to rotate counterclockwise.

During the gear shifting process, the torque of the engine 1 is reduced first, at this time, the rotation speed of the first rotating member 41 is reduced, and the rotation speed of the second rotating member 42 is maintained at the rotation speed before the gear shifting, so that the rotation speed of the second rotating member 42 is greater than the rotation speed of the first rotating member 41, so that the second rotating member 42 drives the second engaging tooth 432 to rotate to the right of the first engaging tooth 431, because the first engaging tooth 431 can rotate in the counterclockwise direction, after the second engaging tooth 432 contacts the first engaging tooth 431, the first engaging tooth 431 and the second engaging tooth 432 are rotated in the counterclockwise direction, so that the first engaging tooth 431 and the second engaging tooth 432 are disengaged from each other, the first rotating member 41 also stops driving the second rotating member 42 to rotate, and the torque of the engine 1 also stops being transmitted to the transmission 3.

In one embodiment, the rotation direction of the first engaging tooth 431 is set according to the relative position between the first rotating member 41 and the second rotating member 42.

Specifically, when the first rotating member 41 is located inside the second rotating member 42, that is, the first rotating member 41 is located on the inner ring, and the second rotating member 42 is located on the outer ring, since the first rotating member 41 is connected to the clutch 2 and the second rotating member 42 is connected to the transmission 3, the first rotating member 41 rotates the second rotating member 42 from the inside, and the rotation direction of the first engaging teeth 431 is the same as the rotation direction of the clutch 2, that is, the rotation direction of the first engaging teeth 431 is the same as the rotation direction of the engine 1.

When the clutch 2 rotates clockwise, the first rotating member 41 will drive the first engaging tooth 431 to rotate clockwise, and the first rotating member 41 will drive the second rotating member 42 to rotate clockwise, at this time, in order to make the first engaging tooth 431 and the second engaging tooth 432 relatively fixed, the first engaging tooth 431 needs to be limited to rotate counterclockwise, that is, the rotation direction of the first engaging tooth 431 should be set to be clockwise.

When the clutch 2 rotates in the counterclockwise direction, the first rotating member 41 will drive the first engaging tooth 431 to rotate in the counterclockwise direction, and the first rotating member 41 will drive the second rotating member 42 to rotate in the counterclockwise direction, at this time, in order to make the first engaging tooth 431 and the second engaging tooth 432 relatively fixed, the first engaging tooth 431 needs to be limited to rotate in the clockwise direction, that is, the rotating direction of the first engaging tooth 431 should be set to be the counterclockwise direction.

When the second rotating member 42 is located in the first rotating member 41, i.e. the first rotating member 41 is located on the outer ring, and the second rotating member 42 is located on the inner ring, since the first rotating member 41 is connected to the clutch 2 and the second rotating member 42 is connected to the transmission 3, the first rotating member 41 drives the second rotating member 42 to rotate from the outside, and the rotating direction of the first engaging teeth 431 is opposite to the rotating direction of the clutch 2, i.e. the rotating direction of the first engaging teeth 431 is opposite to the rotating direction of the engine 1.

When the clutch 2 rotates clockwise, the first rotating member 41 will also drive the first engaging tooth 431 to rotate clockwise, and the first rotating member 41 will drive the second rotating member 42 to rotate clockwise, at this time, in order to make the first engaging tooth 431 and the second engaging tooth 432 relatively fixed, since the first rotating member 41 is on the outer side, it is necessary to limit the first engaging tooth 431 to rotate clockwise, that is, the rotation direction of the first engaging tooth 431 should be set to be counterclockwise.

When the clutch 2 rotates in the counterclockwise direction, the first rotating member 41 will also drive the first engaging tooth 431 to rotate in the counterclockwise direction, and the first rotating member 41 will drive the second rotating member 42 to rotate in the counterclockwise direction, at this time, in order to make the first engaging tooth 431 and the second engaging tooth 432 relatively fixed, since the first rotating member 41 is on the outer side, it is necessary to limit the first engaging tooth 431 to rotate in the counterclockwise direction, that is, the rotation direction of the first engaging tooth 431 should be set to be the clockwise direction.

In one embodiment, in order to make the first catching teeth 431 better fit with the second catching teeth 432, referring to fig. 2, the first catching teeth 431 are extended toward the second rotating member 42 in an oblique direction, the second catching teeth 432 are extended toward the first rotating member 41 in an oblique direction, and the extending directions of the first catching teeth 431 and the second catching teeth 432 are opposite. After the first engaging tooth 431 and the second engaging tooth 432 are obliquely arranged, when the first rotating member 41 drives the first engaging tooth 431 to contact the second engaging tooth 432, the contact area between the first engaging tooth 431 and the engaging tooth is larger, and the interaction force between the first engaging tooth 431 and the second engaging tooth 432 is relatively oblique, so that the first engaging tooth 431 and the second engaging tooth 432 are not easily damaged, and the service lives of the first engaging tooth 431 and the second engaging tooth 432 are prolonged.

In one embodiment, in order to further reduce the time of power interruption, a torque reduction motor may be provided on a flywheel of the engine 1, and the torque reduction speed of the engine 1 may be increased by using the torque reduction motor, so as to reduce the time of vehicle power interruption during gear shifting.

In one embodiment, referring to fig. 3, at least one engaging tooth is uniformly spaced on the first rotating member 41, and similarly, at least one second engaging tooth 432 is also uniformly spaced on the second rotating member 42, and the first engaging tooth 431 and the second engaging tooth 432 which are uniformly spaced can be better matched with each other, so that the first rotating member 41 and the second rotating member 42 can be better matched with each other.

In one embodiment, the gear shifting mechanism in the present application can also use a one-way overrunning clutch, which has the same principle as the gear shifting mechanism provided in the present application; when the clutch is used, the clutch is connected with the inner ring of the one-way overrunning clutch, and the transmission is connected with the outer ring of the one-way overrunning clutch.
