Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle clutches, in particular to a clutch chassis structure and molding processing equipment. Background Art

[0002] Motorcycles are a common means of transportation. They are loved by consumers because of their small size and high maneuverability, but their safety is relatively poor. The motorcycle clutch is an indispensable working part when the motorcycle is started. The structure of the friction plate clutch includes an outer cover and a driven member assembly. The driven member assembly includes components such as an active friction plate, a driven friction plate and a compression spring. The active friction plate is fixedly matched with the outer cover in the circumferential direction. The outer cover is connected to the power output end of the power machinery. The power is input from the outer cover through the active friction plate and the driven friction plate, and is output from the driven disc assembly in which the driven friction disc is fixedly matched in the circumferential direction.

[0003] When the motorcycle clutch is working, when the engine is starting, accelerating rapidly at medium speed, or running at high speed and high load, the protruding plate of the active friction plate and the tooth plate on the clutch cover will generate instantaneous impact force, which can easily wear out the tooth plate. The chassis and tooth plate of the existing motorcycle clutch cover are mostly one-piece structures. If other parts are intact, it is easy to cause the entire clutch cover to be scrapped, which greatly increases the cost of use and even causes a waste of resources. Utility Model Content

[0004] The utility model aims to provide a clutch chassis structure and molding processing equipment, aiming to optimize the design of the chassis structure of the motorcycle clutch cover under the existing technology, reduce the use cost and reduce the waste of resources.

[0005] To achieve the above-mentioned purpose, the utility model provides a clutch chassis structure, including a chassis body and an auxiliary device;

[0006] The chassis body has a cross installation cavity, and the cross installation cavity is arranged below the chassis body in an annular manner;

[0007] The auxiliary device includes an input gear, a connecting pin, an arcuate tooth piece and a locking assembly. The input gear is fixedly connected to the chassis body and is located below the chassis body. The connecting pin is fixedly connected to the chassis body and is located below the chassis body. Positioning protrusions are symmetrically arranged at the bottom of the arcuate tooth piece. The arcuate tooth piece is fixedly connected to the connecting pin and is located on the connecting pin. The locking assembly is arranged on the side of the connecting pin close to the arcuate tooth piece.

[0008] Wherein, the connecting pin has a cross limiting portion, the cross limiting portion cooperates with the cross mounting cavity and is located at the bottom of the connecting pin.

[0009] There are heat dissipation holes on the arc-shaped tooth piece, and the heat dissipation holes penetrate the arc-shaped tooth piece and are vertically arranged on the arc-shaped tooth piece.

[0010] Wherein, the locking assembly includes a locking nut and a lock nut, the locking nut is threadedly connected to the connecting pin and is located on the side of the connecting pin close to the arc-shaped tooth plate; the lock nut is threadedly connected to the connecting pin and is located above the locking nut.

[0011] Wherein, a wear-resistant layer is arranged on the inner arc surface of the arc-shaped tooth piece.

[0012] Among them, a clutch chassis molding and processing equipment can process and manufacture the clutch chassis structure.

[0013] The utility model discloses a clutch chassis structure and forming processing equipment. A cross installation cavity is annularly arranged on the chassis body, which is convenient for installing and setting a connecting pin. An input gear is installed below the chassis body. An arc-shaped tooth piece is installed on the connecting pin through a locking assembly. During use, the arc-shaped tooth piece and the chassis body are arranged as a detachable structure.

Figure 3 is a schematic diagram of the opening position of the cross mounting cavity 102, Figure 4 It is a structural schematic diagram of an arc-shaped tooth piece 105. The utility model provides a clutch chassis structure: including a chassis body 101 and an auxiliary device, the chassis body 101 has a cross mounting cavity 102, the auxiliary device includes an input gear 103, a connecting pin 104, an arc-shaped tooth piece 105 and a locking assembly, the connecting pin 104 has a cross limiting portion 106, the arc-shaped tooth piece 105 has a heat dissipation hole 107, and the locking assembly includes a locking nut 108 and a locking nut 109. The above scheme can realize the optimization design of the chassis structure of the motorcycle clutch cover under the prior art, reduce the use cost, and reduce the waste of resources. It can be understood that the above scheme can realize the optimization of the clutch cover chassis structure.

[0024] In this embodiment, the chassis body 101 can be formed by stamping a steel plate.

[0025] The chassis body 101 has a cross installation cavity 102, and the cross installation cavity 102 is arranged at an annular interval below the chassis body 101; the cross installation cavity 102 is arranged at an annular interval to share the torque force borne by the installation bolt after the connecting pin 104 is installed.

[0026] The auxiliary device includes an input gear 103, a connecting pin 104, an arcuate tooth piece 105 and a locking assembly. The input gear 103 is fixedly connected to the chassis body 101 and is located below the chassis body 101. The connecting pin 104 is fixedly connected to the chassis body 101 and is located below the chassis body 101. Positioning protrusions 110 are symmetrically arranged at the bottom of the arcuate tooth piece 105.
