Description

Technical Field

[0001] The utility model belongs to the technical field of gear shifting mechanisms, in particular to a gear shifting mechanism for a motorcycle. Background Art

[0002] In the international gear, pressing the starter lever downward controls the downshifting effect, while pulling or pushing it upward controls the upshifting effect. However, there are many types of motorcycles, and the design requirements for the engine connecting rod are diverse. When the rider is not sure about the use of the vehicle, pressing the starter lever downward may upshift or downshift. When using different motorcycles, if the shift direction of the motorcycle is due to habit, the gear switching error may occur. For most motorcycles, the operation of the shift lever is relatively consistent. Pressing the shift lever downward usually achieves downshifting, that is, switching the motorcycle from a high gear to a low gear, so that the engine speed increases. Pulling or pushing the shift lever upward will achieve upshifting, that is, switching the motorcycle from a low gear to a high gear, reducing the engine speed. However, some motorcycle models or manufacturers may adopt a different shifting method from the traditional one, which may be due to their specific technical needs, market trends or preferences. When using motorcycles with different shifting methods, riders may shift gears incorrectly because they are not sure about the vehicle's shifting method, or they may shift gears incorrectly due to long-term riding habits. Utility Model Content

[0003] In order to solve the problem in the above-mentioned prior art that when using a motorcycle with different gear shifting methods, the rider may make a gear shift error due to uncertainty about the vehicle's gear shifting method or due to long-term riding habits, the utility model proposes a motorcycle gear shifting mechanism that can conveniently switch the rotation direction of the gear shift pedal corresponding to upshifting and downshifting.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a motorcycle shift mechanism, including a fixed plate, a pedal mounting plate, a shift pedal, a first push rod, a push rod connecting plate and a second push rod;

[0005] The fixing plate is mounted on a fixing tube on a frame of a motorcycle, the footrest mounting plate is mounted on the fixing plate by screws, a footrest is provided on one side of the footrest mounting plate, the push rod connecting plate and the shift pedal are both mounted on the other side of the footrest mounting plate away from the footrest by screws, and both the push rod connecting plate and the shift pedal are rotatable;

[0006] The push rod connecting plate comprises a first mounting tube, a first extension plate and a second extension plate, the center of the first mounting tube is provided with a through hole for screws to pass through, when the push rod connecting plate is mounted on the pedal mounting plate, the shift connecting rod of the engine is located above the first mounting tube, and the second extension plate is located above the first mounting tube and deviates to one side;

[0007] The two ends of the first push rod are rotatably connected to the first extension plate and the shift pedal respectively, and when the shift pedal rotates, the push rod connecting plate can be driven to rotate by the first push rod;

[0008] The two ends of the second push rod are rotatably connected to the second extension plate and the shift connecting rod respectively. When the push rod connecting plate rotates, the shift connecting rod can be driven to rotate by the second push rod. Rotating the shift connecting rod can switch the gear of the engine.

[0009] When the shift link is not rotating, the axis of the rotational connection between the shift link and the second push rod is at the same level as the axis of the shift link when it is rotating;

[0010] The push rod connecting plate can be removed and the direction of the first mounting tube can be reversed and reinstalled on the pedal mounting plate, so that the second extension plate is biased to the other side. When the shift pedal is stepped on or lifted, the shift pedal drives the push rod connecting plate to rotate through the first push rod. When the push rod connecting plate rotates clockwise, if the push rod connecting plate is biased to the left, the push rod connecting plate pushes the end of the shift connecting rod upward through the second push rod to rotate the shift connecting rod. If the push rod connecting plate is biased to the right, the push rod connecting plate pulls the end of the shift connecting rod downward through the second push rod to rotate the shift connecting rod in the other direction. The operation required for switching upshift or downshift can be changed by simply reversing the direction of the push rod connecting plate, so that upshift when the shift pedal is stepped on is changed to downshift when the shift pedal is stepped on, or downshift when the shift pedal is stepped on is changed to upshift when the shift pedal is stepped on.

[0011] Furthermore, two second extension plates are provided on the push rod connecting plate, and when the push rod connecting plate is installed on the pedal mounting plate, the two second extension plates are biased to different sides, and the end of the second push rod is rotatably connected to one of the second extension plates. The rotation direction of the shift pedal corresponding to upshifting and downshifting can be switched by simply connecting the second push rod to the other second extension plate without removing the push rod connecting plate.

Remove the screw used to connect and fix the second extension plate to the first mounting tube, rotate the second extension plate so that the positioning hole coincides with the threaded hole on the other limiting plate, and the second extension plate is deviated to the other side at this time, and then screw in the screw to fix it, so that the rotation direction of the shift pedal corresponding to upshift and downshift can be switched.

[0013] Further, the shift pedal is provided with a second mounting tube, the center of the second mounting tube is provided with a through hole, a screw passes through the second mounting tube to mount the shift pedal on the foot mounting plate, the second mounting tube and the first mounting tube are located at the same horizontal position, the shift pedal rotates around the second mounting tube, a third extension plate is provided at the bottom of the second mounting tube, and the first push rod is rotatably connected to the third extension plate of the shift pedal. When the shift pedal rotates, the push rod connecting plate and the shift pedal rotate in the same direction.

[0014] Furthermore, both ends of the first push rod and both ends of the second push rod are provided with connecting pieces, and both ends of the first push rod are connected to the first extension plate and the shift pedal through the connecting pieces, and both ends of the second push rod are connected to the second extension plate and the shift connecting rod through the connecting pieces.

[0015] Furthermore, the connecting member is provided with a rotating sleeve and a connecting column, the rotating sleeve is provided with a cylindrical groove, one end of the connecting column is provided with an external thread, the first extension plate, the second extension plate and the third extension plate are all provided with threaded holes, one end of the connecting column provided with the external thread is screwed into the threaded hole, and the other end of the connecting column is inserted into the groove on the rotating sleeve, and the connecting column and the rotating sleeve can rotate relative to each other.

[0016] Furthermore, the connecting piece is made of rubber, which has a certain elasticity and can adapt to the error of the diameter of the connecting column, making it more convenient to disassemble and install.

[0017] The beneficial effects of a motorcycle shift mechanism of the utility model are as follows: when the shift pedal is stepped on or lifted, the shift pedal drives the push rod connecting plate to rotate through the first push rod. When the push rod connecting plate rotates clockwise, if the push rod connecting plate deviates to the left, the push rod connecting plate pushes the end of the shift connecting rod upwards through the second push rod to rotate the shift connecting rod. If the push rod connecting plate deviates to the right, the push rod connecting plate pulls the end of the shift connecting rod downwards through the second push rod to rotate the shift connecting rod in the other direction. The rotation direction of the shift pedal corresponding to upshifting and downshifting can be switched by turning the direction of the push rod connecting plate. Before driving a new motorcycle, the shift direction of the motorcycle is adjusted to the direction the rider is accustomed to, so as to avoid shifting errors affecting riding and provide a better driving experience. Two second extension plates are provided on the push rod connecting plate, and the push rod connecting plate is installed on the pedal When the two second extension plates are mounted on the mounting plate, the two second extension plates are biased to different sides. There is no need to remove the push rod connecting plate.

The second extension plate can rotate around the first mounting tube. A positioning hole is provided on the second extension plate. The first mounting tube is provided with two limit plates. Both limit plates are provided with threaded holes. When the second extension plate is rotated until the positioning hole coincides with the threaded hole on one limit plate, a screw is provided to pass through the positioning hole and be screwed into the threaded hole to connect and fix the second extension plate to the first mounting tube. The screw used to connect and fix the second extension plate to the first mounting tube is removed.

The screw is then screwed in to fix it, and the rotation direction of the shift pedal corresponding to upshifting and downshifting can be switched. BRIEF DESCRIPTION OF THE DRAWINGS

When the shift pedal 3 is stepped on or lifted, the shift pedal 3 drives the push rod connecting plate 5 to rotate through the first push rod 4. When the push rod connecting plate 5 rotates clockwise, if the push rod connecting plate 5 deviates to the left, the push rod connecting plate 5 pushes the end of the shift link 7 upwards through the second push rod 6 to rotate the shift link 7. If the push rod connecting plate 5 deviates to the right, the push rod connecting plate 5 pulls the end of the shift link 7 downwards through the second push rod 6 to rotate the shift link 7 in the other direction.
