Abstract

The invention relates to transformation of clutch platen assemblies and provides a labor-saving platen assembly structure capable of increasing the lever ratio. The labor-saving platen assembly structure capable of increasing the lever ratio is provided with a platen. A cover plate is installed on the platen through connecting pieces. A diaphragm spring is installed between the cover plate and the platen. A plurality of strip-shaped installation holes are formed in the diaphragm spring, and rivets are installed in the installation holes. The diaphragm spring is installed on the cover plate through the rivets which are located in the strip-shaped installation holes. A pressing ring is clamped between the diaphragm spring and the cover plate. A supporting ring is clamped between the diaphragm spring and pillow blocks of the rivets. The pressing ring and the supporting ring are installed outside column bodies of the rivets. Particularly, the diameter of the supporting ring is larger than that of the pressing ring. By the adoption of the labor-saving platen assembly structure capable of increasing the lever ratio, the problem that according to an existing vehicle clutch platen assembly, the separating force of a clutch is increased along with the increase of the pressing force between a diaphragm spring and a platen is solved; the labor-saving platen assembly structure capable of increasing the lever ratio is mainly used for transformation of the vehicle clutch platen assembly.

Description

Technical field: [0001] The invention relates to the transformation of a clutch pressure plate assembly, which is a pressure plate assembly structure with increased lever ratio and labor saving. Background technique: [0002] The leverage ratio of the pressure fulcrum between the diaphragm spring and the pressure plate in the prior art vehicle clutch pressure plate assembly is a definite value. The problem existing in the prior art vehicle clutch pressure plate assembly is that the diaphragm spring The greater the pressing force between the pressure plate and the clutch, the greater the separation force of the clutch. The application of this feature of the pressure plate assembly to the clutch of a heavy truck is that it takes a lot of effort to operate the clutch separation, and it is easy to cause the operator to drive for a long time. Fatigue puts forward new requirements for the transformation of the existing vehicle clutch pressure plate assembly. Invention content: ...
