Normally engaged wet type clutch

Abstract

The invention is applicable to various vehicles, and particularly relates to a normally engaged wet type clutch used on a car. The normally engaged wet type clutch comprises a motive power output shaft, an input shaft, a driven clutch hub, a driving clutch hub, a driven friction sheet, an active friction sheet and a thrust disc, wherein the motive power output shaft and the input shaft are respectively arranged on a casing and an end cover through bearings, the driven clutch hub and the driving clutch hub are respectively and fixedly arranged on the output shaft and the input shaft, the driven friction sheet is connected onto the driven clutch hub, the driving friction sheet is connected onto the driving clutch hub, the thrust disc is leaned and arranged on the end surface of the driven friction sheet, a diaphragm spring is arranged on the outer side of the thrust disc and is butted and connected onto the outer wall of the diaphragm spring through a pre-tightening screw bolt which is used as a lever fulcrum and is fixedly arranged on the driven clutch hub, a piston arranged on the input shaft diameter is butted and connected onto the inner edge of the diaphragm spring through the thrust bearing, and in addition, the pre-tightening screw bolt is regulated so that the driving and driven friction sheets are in the normally engaged states. The range of the torque transmitted by the wet type clutch is greater, the service life of the clutch can be prolonged, and the driving comfort is better.

Description

technical field [0001] The invention relates to a constantly engaged wet clutch suitable for various vehicles, especially passenger cars. Background technique [0002] Clutch is an important part in the power transmission process of the transmission system. It has gone through nearly a hundred years of history with the birth and development of the vehicle. The main functions of the clutch include ensuring the smooth start of the car, realizing smooth shifting, and preventing the overload of the transmission system. It is one of the main components of the transmission. The clutch is divided into dry type and wet type according to the working environment of the friction surface. [0003] In the automotive mechanical transmission system powered by an internal combustion engine, the clutch is at the head end of the transmission system and is an important part of the vehicle transmission system. It is also a frequently used component that is frequently engaged and slipped during ...
