Problems solved by technology

Therefore, the slotted design will not only increase the axial deformation of the thrust plate and the casing, but also make the actuator need to bear extra load at the moment when it starts to work, so that the actuator cannot work normally
Therefore, this solution cannot be adopted when the above two characteristics cannot appear.

Embodiment Construction

[0020] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0021] Such as figure 1 , 2 As shown, the diaphragm spring described in this embodiment is a disc-shaped structure, including: a disc spring part 1, an engaging finger part 2 and a stress release hole 3, wherein: several engaging finger parts 2 with the same structure are connected by a diaphragm spring The center of the circle 4 is symmetrical to the center, and the outer end of the engaging finger part 2 is fixedly connected with the disc spring part 1, and several stress release holes 3 are arranged on the disc spring part 1 along the circumferential direction.

[0022] The positions of the stress release hole...

Abstract

The invention relates to a diaphragm spring for a normally open type clutch, belonging to the technical field of the automatic clutch of the automobile. The diaphragm spring is of disc-shaped structure and comprises a disc-spring part, a plurality of jointing finger parts and a plurality of stress releasing holes, wherein the plurality of jointing finger parts with the same structure are centrally symmetrical by the center of a circle of the diaphragm spring; and the outer ends of the jointing finger parts are fixedly connected with the disc-spring part which is provided with the plurality of stress releasing holes along the peripheral direction. The diaphragm spring not only reserves the advantages of being capable of reducing resilience force and having zero rigidity in a wearing route of a frictional plate, but also overcomes the problem of overlarge pressure, thus leading the elastic deformation of a thrust plate and a housing to decrease, leading the starting operation of an executive device to become easy and leading the load borne in the process of the executive device to obviously decrease.

Description

technical field [0001] The invention relates to a structural part of a clutch device in the technical field of automobile engineering, in particular to a diaphragm spring for a normally open clutch. Background technique [0002] According to the arrangement of the diaphragm spring in the clutch, the clutch can be divided into two types: normally closed and normally open. The classification is based on whether the pressure plate is pressed against the friction plate or not in contact with the friction plate when the actuator is not working. Although the normally closed clutch has the advantage that the actuator has no energy consumption when the car is running, when the clutch is fully engaged and the actuator cannot work normally, the disadvantage that the clutch cannot be disengaged in time according to the driver's request is obvious. This not only increases the difficulty of parking, but also increases the traffic safety hazard. The normally open clutch can effectively s...
