[0002] For the reverse gear mechanism of large-displacement motorcycles, since the reverse gear mechanism needs to be newly added on the original basis, the realization of space and function often becomes the main limitation. The reverse gear mechanism of motorcycles currently on the market is usually a shift fork type reverse gear mechanism. The shift fork type reverse gear mechanism generally realizes the disconnection and connection function of the power between the shafts by moving the shift fork back and forth on the shift fork shaft. This method is relatively mature and stable, but it has a large space requirement in terms of overall layout and structure, and the structure is also relatively complex. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model aims to provide a motorcycle, whose reverse gear structure is compactly arranged and simple in structure.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Furthermore, the guide rail slider structure includes a first position and a second position. The driving motor changes the rotation direction to place the guide rail slider structure in the first position or the second position. When the guide rail slider structure is in the first position, the output shaft and the speed change assembly are separated. When the guide rail slider structure is in the second position, the output shaft and the speed change assembly are transmission connected.

[0009] Furthermore, the driving member is configured as an elastic member, and the guide rail slider structure also includes a third position. Along the front-to-rear direction of the reverse gear system, the third position is located between the first position and the second position.

A through hole is provided on the connecting plate, and the eccentric motor shaft at least partially passes through the through hole. A protrusion is also provided on the connecting plate, and the protrusion is at least partially located in the driving member.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the utility model.

[0024] like Figure 1 A motorcycle 100 is shown, and the motorcycle 100 includes a frame 11, a body cover 12, a running assembly 13, a powertrain 14, and a transmission system 15. The frame 11 constitutes the basic framework of the motorcycle 100, and the frame 11 is used to carry other components of the motorcycle 100. The body cover 12 is at least partially disposed on the frame 11, and the body cover 12 is used to protect the internal parts of the motorcycle 100. The running assembly 13 is used to drive the motorcycle 100 to move, and the running assembly 13 includes a front wheel 131 and a rear wheel 132 disposed below the frame 11. The powertrain 14 is at least partially disposed on the frame 11, and the powertrain 14 is used to provide power for the motorcycle 100.

[0025] like Figure 2 and Figure 3As shown, the power assembly 14 includes a housing 141, which is used to carry and protect the internal parts of the power assembly 14. The power assembly 14 also includes an engine 142 and a speed change mechanism 143. The engine 142 and the speed change mechanism 143 are arranged in the housing 141. The engine 142 includes a crankshaft 1421, and the speed change mechanism 143 includes a main shaft 1431 and a secondary shaft 1432. The main shaft 1431 is transmission-connected to the crankshaft 1421, so that the engine 142 can transmit power to the speed change mechanism 143. The main shaft 1431 is also transmission-connected to the secondary shaft 1432. The main shaft 1431 and the secondary shaft 1432 are respectively provided with mutually meshing gear sets. The transmission ratio between the main shaft 1431 and the secondary shaft 1432 can be changed by changing the relative position between the main shaft 1431 and the secondary shaft 1432, so that the main shaft 1431 can be controlled to transmit power to the secondary shaft 1432. The power assembly 14 transmits driving force to the secondary shaft 1432, so that the secondary shaft 1432 can rotate in a preset direction, thereby driving the motorcycle 100 forward. Further, the secondary shaft 1432 is drivingly connected to the front wheel 131 and / or the rear wheel 132 of the motorcycle 100, so that the engine 142 outputs power to the front wheel 131 and / or the rear wheel 132 through the speed change mechanism 143. The motorcycle 100 also includes a reverse gear system 15, and the secondary shaft 1432 is drivingly connected or disconnected from the reverse gear system 15. Specifically, the reverse gear system 15 also includes a reverse gear power mechanism 151 and a reverse gear transmission mechanism 152. The reverse gear power mechanism 151 and the reverse gear transmission mechanism 152 are transmission-connected. The reverse gear power mechanism 151 is used to provide power for the reverse gear system 15, thereby driving the motorcycle 100 to reverse. The reverse gear transmission mechanism 152 is used to transmit the power generated by the reverse gear power mechanism 151 to the speed change mechanism 143, and transmit it to the front wheel 131 and / or the rear wheel 132 through the speed change mechanism 143. In the present application, the reverse gear power mechanism 151 can be set as a reverse gear motor. When the reverse gear power mechanism 151 is finally set to be transmission-connected with the secondary shaft 1432, it can drive the secondary shaft 1432 to move in a direction opposite to the preset direction, thereby causing the traveling component 13 of the motorcycle 100 to move backward, thereby realizing the reverse function. When the motorcycle 100 is in a reversing state, the reverse gear system 15 is in transmission connection with the secondary shaft 1432. At this time, the main shaft 1431 and the secondary shaft 1432 are in a separated state. The reverse gear system 15 outputs power to the secondary shaft 1432 through the reverse gear power mechanism 151, so that the secondary shaft 1432 rotates in a direction opposite to the preset direction, thereby changing the rotation direction of the front wheel 131 and / or the rear wheel 132 of the motorcycle 100, thereby realizing the reversing function of the motorcycle 100. When the motorcycle 100 is in a forward state, the reverse gear system 15 is separated from the speed change mechanism 143. At this time, the main shaft 1431 and the secondary shaft 1432 are in a transmission connection state, and the motorcycle 100 can travel forward normally. The reverse gear system 15 will not interfere with the normal travel or gear shifting of the motorcycle 100.

[0026] like Figure 4 As shown, the reverse gear system 15 further includes a driving mechanism 153 and a switching mechanism 154. The switching mechanism 154 is at least partially disposed between the reverse gear transmission mechanism 152 and the secondary shaft 1432. The switching mechanism 154 is also arranged in transmission connection with the driving mechanism 153. The switching mechanism 154 can control the connection and disconnection of the driving force between the reverse gear transmission mechanism 152 and the secondary shaft 1432 under the drive of the driving mechanism 153. Specifically, the driving mechanism 153 can provide the switching mechanism 154 with power for translation in a certain direction, so that the switching mechanism 154 can translate in the direction or in the direction opposite to the direction. Specifically, the switching mechanism 154 includes an input shaft 1541 and an output shaft 1542, the input shaft 1541 and the output shaft 1542 are connected by splines, the driving mechanism 153 and the output shaft 1542 are connected in driving connection, the output shaft 1542 is arranged between the secondary shaft 1432 and the input shaft 1541, and the output shaft 1542 can move axially relative to the input shaft 1541, so that the switching mechanism 154 can be engaged or disengaged with the gear of the secondary shaft 1432, thereby realizing the driving connection or disengagement of the reverse gear system 15 and the speed change mechanism 143. Through the above arrangement, the reverse gear system 15 can be made independent of the transmission system 15 of the motorcycle 100 on the basis of realizing the reverse function of the motorcycle 100 by driving the switching mechanism 154 through the driving mechanism 153, so as to avoid the reverse gear system 15 interfering with the gear shifting of the motorcycle 100 during normal driving of the motorcycle 100.

[0027] In addition, the switching mechanism 154 is also connected to the reverse gear transmission mechanism 152 in a transmission connection, so that the power generated by the reverse gear power mechanism 151 can be transmitted to the switching mechanism 154, and then transmitted to the secondary shaft 1432 through the switching mechanism 154, thereby changing the rotation direction of the secondary shaft 1432 and realizing the reverse of the motorcycle 100. Among them, the reverse gear transmission mechanism 152 also includes a transmission chain 1521, and the reverse gear transmission mechanism 152 and the input shaft 1541 are connected in a transmission connection through the transmission chain 1521. Through the above arrangement, the chain transmission has a simple structure, a high transmission efficiency, and can also bear a large load, thereby improving the connection strength and connection stability of the reverse gear transmission mechanism 152 and the switching mechanism 154, and further improving the working life of the reverse gear system 15.

[0028] like Figure 5As shown, as an implementation method, the driving mechanism 153 includes a driving motor 1531 and a driving member 1532, the driving member 1532 is at least partially arranged on the driving motor 1531, the driving member 1532 rotates along the rotation axis 101 of the driving member 1532, the driving motor 1532 rotates along the rotation axis 102 of the driving motor 1531, and the rotation axis 101 of the driving member 1532 and the rotation axis 102 of the driving motor 1531 are basically parallel. Specifically, an eccentric motor shaft 1531a is provided on the driving motor 1531. The "eccentric" mentioned above means that the axis of the eccentric motor shaft 1531a is parallel to but not coincident with the rotation axis 102 of the driving motor 1531, and the axis of the eccentric motor shaft 1531a rotates along the rotation axis 102 of the driving motor 1531. The eccentric motor shaft 1531a is at least partially located in the driving member 1532, so that when the driving motor 1531 drives the eccentric motor shaft 1531a to rotate, the eccentric motor shaft 1531a can also drive the driving member 1532 to rotate. The driving mechanism 153 also includes a guide rail slider structure 1533, which has a degree of freedom of movement along the axis direction of the output shaft 1542. The guide rail slider structure 1533 connects the driving member 1532 and the output shaft 1542; when the driving motor 1531 rotates, the eccentric motor shaft 1531a controls the output shaft 1542 to move along the axis direction through the driving member 1532. Through the above arrangement, in the prior art, the driving mechanism 153 controls the movement of the shift fork through the gear rack structure, so that the reverse gear transmission mechanism 152 and the switching mechanism 154 are connected in transmission, so as to realize the reverse function of the motorcycle 100. This reverse gear control method makes the reverse gear system 15 complex in structure and large in size, occupies a large space in the housing 141, and affects the arrangement of other components in the power assembly 14. In the present application, the driving motor 1531 can directly control the movement of the switching mechanism 154 through the driving member 1532 and the guide rail slider structure 1533 to realize the transmission connection or separation between the switching mechanism 154 and the secondary shaft 1432, thereby simplifying the structure of the reverse gear system 15 and reducing the occupied area of ​​the reverse gear system 15 in the housing 141, and optimizing the working process of the reverse gear system 15 and improving the working efficiency of the reverse gear system 15.

[0029] As an optional implementation method, a connecting plate 1534 is arranged between the eccentric motor shaft 1531a and the driving member 1532. The connecting plate 1534 can rotate along the rotation axis 101 of the driving member 1532, that is, the connecting plate 1534 has a rotational freedom along the rotation axis 101 of the driving member 1532, and a through hole 1534a is arranged on the connecting plate 1534. The eccentric motor shaft 1531a is at least partially penetrated by the through hole 1534a, wherein the through hole 1531a can be set as a waist-shaped hole, and a protrusion 1534b is also arranged on the connecting plate 1534, and the protrusion 1534b is at least partially located in the driving member 1532. When the eccentric motor shaft 1531a rotates, the eccentric motor shaft 1531a drives the connecting plate 1534 to rotate and drives the driving member 1532 to rotate along the rotation axis 101 of the driving member 1532 through the protrusion 1534b. Through the above arrangement, the connecting plate 1534 can make the eccentric motor shaft 1531a drive the driving member 1532 to rotate more stably, and the waist-shaped hole design makes the connecting plate 1534 and the driving member 1532 swing back and forth only within a certain angle during the rotation of the eccentric motor shaft 1531a, thereby reducing the volume of the driving mechanism 153 and improving the compactness of the structure of the driving mechanism 153. In addition, the protrusion 1534b on the connecting plate 1534 can also make the swing of the driving member 1532 more stable and controllable, thereby improving the working stability of the driving mechanism 153.

[0030] like Figure 6 and Figure 7As shown, in this embodiment, the guide rail slider structure 1533 includes a first position and a second position. The driving motor 1531 changes the rotation direction to make the guide rail slider structure 1533 in the first position or the second position, thereby driving the output shaft 1542 to move. When the guide rail slider structure 1533 is in the first position, the output shaft 1542 and the secondary shaft 1432 are separated. When the guide rail slider structure 1533 is in the second position, the output shaft 1542 and the secondary shaft 1432 are connected in transmission. In the prior art, the output shaft 1542 and the secondary shaft 1432 are always in a meshing state, and the reverse function of the motorcycle 100 is realized by changing the connection state of the input shaft 1541 and the output shaft 1542 through the driving mechanism 153, that is, when the reverse gear transmission mechanism 152 is connected to the output shaft 1542, the reverse gear transmission mechanism 152 can transmit torque to the output shaft 1542, so that the output shaft 1542 drives the secondary shaft 1432 to change the rotation direction and rotate in a direction opposite to the preset direction. When the reverse gear transmission mechanism 152 is separated from the output shaft 1542, the secondary shaft 1432 rotates in the preset direction, and the output shaft 1542 rotates together with the secondary shaft 1432. This connection method makes the output shaft 1542 always in a rotating state. After the motorcycle 100 is used for a long time, the output shaft 1542 is severely worn, thereby causing the reverse gear system 15 to malfunction. Through the above arrangement, in the present application, the output shaft 1542 is always in meshing state with the reverse gear transmission mechanism 152, and the reverse function of the motorcycle 100 is realized by changing the transmission connection or separation between the output shaft 1542 and the secondary shaft 1432. When the reverse gear system 15 is working, the position of the output shaft 1542 is changed to make the output shaft 1542 and the secondary shaft 1432 mesh. When the reverse gear system 15 is not working, the output shaft 1542 is completely separated from the secondary shaft 1432, so that when the reverse gear system 15 is not working, the output shaft 1542 can be separated from the transmission system 15 of the motorcycle 100, avoiding overwork and wear of the output shaft 1542 due to long-term operation, thereby improving the service life and working stability of the reverse gear system 15. In addition, the separation of the switching mechanism 154 and the secondary shaft 1432 can also avoid designing a complex lubricating oil circuit for the switching mechanism 154, thereby facilitating the layout of the lubricating oil circuit.

[0031] As an optional implementation, the driving member 1532 is configured as an elastic member, and the guide rail slider structure 1533 also includes a third position, and along the front-to-back direction of the reverse gear system 15, the third position is located between the first position and the second position. When the guide rail slider structure 1533 is in the third position, the output shaft 1542 and the secondary shaft 1432 abut against each other, and the driving member 1532 stores the preload force and releases the elastic potential energy in a preset direction. In the present application, the driving member 1532 is configured as a torsion spring, and both ends of the torsion spring are connected to the guide rail slider structure 1533. The eccentric motor shaft 1531a moves one end of the torsion spring during the rotation process to drive the guide rail slider structure 1533 to move, and the other end of the torsion spring undergoes elastic deformation during the rotation of the torsion spring and generates an elastic force to drive the guide rail slider structure 1533. Specifically, the gears on the output shaft 1542 and the secondary shaft 1432 abut against each other, that is, the gears on the output shaft 1542 and the secondary shaft 1432 are stuck, and the gears of the output shaft 1542 and the secondary shaft 1432 are blocked and cannot be in meshing state, and the reverse gear system 15 cannot normally engage in gear. During the process of the eccentric motor shaft 1531a driving one end of the torsion spring to rotate, the other end of the torsion spring stores elastic force due to its own elastic deformation and is converted into a thrust applied to the moving direction of the guide slider mechanism, thereby applying a thrust to the output shaft 1542. In this case, the driver can move the motorcycle 100 forward and backward to rotate the secondary shaft 1432 or start the reverse gear power mechanism 151 to rotate the output shaft 1542, so that the output shaft 1542 can engage with the secondary shaft 1432, so that the motorcycle 100 can engage in reverse gear. Through the above arrangement, when the top gear of the reverse gear system 15 is stuck, the driving member 1532 can use its own elastic force to drive the output shaft 1542 to engage with the speed change mechanism, so that the motorcycle 100 can be engaged in the reverse gear position, thereby avoiding the top gear from being stuck and improving the working stability of the reverse gear system 15. It can be understood that the torsion spring is only a preferred embodiment in the embodiment of the present application, and the driving member 1532 can also be set as other elastic members.

[0032] like Figure 5 As shown, the switching mechanism 154 includes a connecting rod 1543, and the connecting rod 1543 is respectively fixedly connected to the guide rail slider structure 1533 and the output shaft 1542. Specifically, a mounting groove 1542a is provided on the switching mechanism 154, and the connecting rod 1543 is fixedly connected to the output shaft 1542 through the mounting groove 1542a. Through the above arrangement, the connecting rod 1543 connects the guide rail slider structure 1533 and the output shaft 1542, so that the output shaft 1542 can be driven to move during the movement of the guide rail slider, thereby realizing the transmission connection or separation of the output shaft 1542 and the secondary shaft 1432, and the connecting rod 1543 can also improve the connection stability between the output shaft 1542 and the guide rail slider structure 1533.

[0033] like Figure 5As shown, the driving motor 1531 is also provided with a sensor 1531b for detecting the position of the guide rail slider structure 1533. The sensor 1531b is basically set at a first position and a second position. The sensor 1531b is electrically connected to the dashboard of the motorcycle 100 to send reverse gear status information to the driver. Specifically, when the sensor 1531b detects that the guide rail slider structure 1533 is in the first position, the sensor 1531b outputs the state information that the reverse gear of the motorcycle 100 is disengaged to the instrument panel; when the sensor 1531b detects that the guide rail slider structure 1533 is in the second position, the sensor 1531b outputs the state information that the motorcycle 100 is in the reverse gear to the instrument panel; when the sensor 1531b detects that the guide rail slider structure 1533 is neither in the second position nor in the first position, the output shaft 1542 and the secondary shaft 1432 are stuck in the top gear, and the sensor 1531b outputs the information that the reverse gear state is abnormal to the instrument panel, reminding the driver to start the reverse gear power mechanism 151 or move the vehicle forward and backward to solve the problem of the top gear stuck in the reverse gear system 15. Through the above settings, the setting of the sensor 1531b can make the driver more aware of the state of the reverse gear system 15, thereby improving the driving experience of the driver and the driving safety of the motorcycle 100.
