[0002] The function of motorcycle clutch is to transmit or cut off the power transmission between the crankshaft of motorcycle engine and gearbox. The motorcycle clutch includes clutch pressure plate and operating arm. The operating arm controls the separation or closing of pressure plate by the separation pull rod, thereby realizing the disconnection or connection between engine and transmission system. The motorcycle clutch has built-in compression spring. After the compression spring shifts gears, the pressure plate automatically resets and closes, making the pressure plate in a normally closed state.

[0003] Chinese patent document CN207830411U discloses a motorcycle clutch, including a clutch cover, a clutch release sleeve is arranged at the center of the cover, a driven gear A and a driven gear B are arranged on the outer end surface of the clutch cover and the clutch release sleeve respectively, a clutch center sleeve is arranged in the clutch cover, a plurality of spring accommodating windows are evenly distributed on the body end surface of the driven gear A, a buffer spring is arranged in the spring accommodating window, and the buffer spring is in contact with the outer end surface of the clutch cover.

[0004] The prior art has the following deficiencies: In the prior art, the clutch is separated and engaged by a clutch actuator through electrical or hydraulic control, and when a control system fails, the gear cannot be shifted, causing a safety accident. Summary of the invention

[0006] In order to facilitate independent manual operation, a connecting head is provided at the connecting end of the pull rod and the manual operating arm. The connecting head is connected to the pull rod through a connecting rod. A storage space for accommodating the connecting head is provided in the manual operating arm, and the connecting head only moves in the storage space.

[0007] In order to avoid the automatic operating arm interfering with the manual operating arm when the clutch is automatically controlled, there is a movable gap at the end of the pull rod in the manual operating arm, and the distance of the gap is greater than or equal to the displacement of the pressure plate. When the automatic operating arm rotates to push the push rod and the pull rod to move axially, the movable gap provides the pull rod with movement space in the manual operating arm, thereby avoiding interference with the manual operating arm during automatic operation.

[0008] Preferably, the push rod and the pull rod are coaxially arranged in the clutch main shaft.

[0009] Preferably, a limiting step is provided on the pull rod, the pull rod passes through the through hole of the clutch pressure plate, the limiting step is arranged toward the automatic operating arm, and the limiting step pushes the clutch pressure plate to move axially toward the manual operating arm.

[0010] Preferably, a connecting hole is provided at the connecting end of the pull rod and the push rod, and the end of the push rod is inserted into the connecting hole.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model can be operated separately through two sets of operating mechanisms. In automatic gear shifting, the clutch is controlled to engage and disengage by axially pulling the pull rod through the automatic operating arm; in manual gear shifting, the clutch is controlled to engage and disengage by axially pulling the pull rod through the manual operating arm. It can realize both electronically controlled fully automatic clutch operation and manual clutch operation. Manual control and automatic control can independently complete the control of the clutch without interfering with each other, thereby improving the controllability of the motorcycle, improving the fault tolerance during use, and improving the safety during driving.

[0013] 2. The overall structure is compact, and the engine installation space is not increased while increasing the functions, meeting the miniaturization of the motorcycle structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 It is a cross-sectional view of the engine clutch operating mechanism of the utility model. DETAILED DESCRIPTION

[0016] The following is further described in detail through specific implementation methods:

[0017] 1. The reference numerals in the drawings of the specification include: clutch main shaft 1, push rod 2, pull rod 3, automatic operating arm 4, manual operating arm 5, clutch pressure plate 6, circular connector 7, connecting rod 8, accommodating space 9, movable gap 10, limiting step 11, through hole 12, annular groove 13, connecting hole 14, clutch assembly 15.

[0018] Example 1

[0019] like Figure 1 and 2 As shown, an engine clutch operating mechanism includes a clutch main shaft 1, a push rod 2, a pull rod 3, an automatic operating arm 4 and a manual operating arm 5. The right end of the push rod 2 pushes against the side of the lower part of the automatic operating arm 4, the left end of the push rod 2 contacts the right end of the pull rod 3, the left end of the pull rod 3 is connected to the lower part of the manual operating arm 5, the pull rod 3 is connected to the clutch pressure plate 6 in the clutch assembly 15, and a return spring is built in the clutch assembly 15. The return spring makes the clutch pressure plate 6 in a normally closed state. When shifting is required, in the automatic state: the upper part of the automatic operating arm 4 rotates to push the push rod 2 and the pull rod 3 to move axially together in the direction of the manual operating arm 5, and the clutch pressure plate 6 is separated for shifting; in the manual state: the upper part of the manual operating arm 5 rotates to pull the pull rod 3 axially alone, and the clutch pressure plate 6 is separated for shifting. The return spring built in the clutch assembly 15 is a conventional setting, which will not be described in detail here.

[0020] A circular connector 7 is provided at the connecting end of the pull rod 3 and the manual operating arm 5, and the circular connector 7 is connected to the pull rod 3 through a connecting rod 8. A receiving space 9 for receiving the circular connector 7 is provided in the manual operating arm 5, and the receiving space 9 has a movable gap 10. The circular connector 7 only moves in the receiving space 9; the distance of the gap is equal to the displacement of the pressure plate. When the upper part of the automatic operating arm 4 rotates to push the push rod 2 and the pull rod 3 to move axially, the movable gap 10 provides the pull rod 3 with movement space in the manual operating arm 5, and the manual operating arm 5 is always in a stationary state, thereby avoiding interference with the manual operating arm 5 during automatic operation.

[0021] When the clutch pressure plate 6 is in the normally closed state, the circular connector 7 is on the right side of the accommodating space 9, and the left side is the movable gap 10. When the upper part of the automatic operating arm 4 rotates and shifts to push the push rod 2 and the pull rod 3 to move axially, the circular connector 7 moves to the leftmost side of the accommodating space 9 without interfering with the manual operating arm 5; when the upper part of the manual operating arm 5 rotates and shifts, it directly pulls the push rod 2 to move axially without interfering with the automatic operating arm 4.

[0022] The push rod 2 and the pull rod 3 are coaxially arranged in the clutch main shaft 1 .

[0023] A limiting step 11 is provided on the pull rod 3, and the pull rod 3 passes through a through hole 12 at the center of the clutch pressure plate 6. An annular groove 13 cooperating with the limiting step 11 is provided at the through hole 12. The limiting step 11 is arranged toward the direction of the automatic operating arm 4, and the limiting step 11 pushes the clutch pressure plate 6 to move axially toward the manual operating arm 5.

[0024] A connecting hole 14 is provided at the connecting end of the pull rod 3 and the push rod 2, and the end of the push rod 2 is inserted into the connecting hole 14. The size of the connecting hole 14 is slightly larger than the size of the end of the push rod 2, which facilitates the pull rod 3 to move alone and the push rod 2 to push the pull rod 3 to move.
