Multi-disc clutch assembly

Abstract

The invention discloses a multi-disc clutch assembly. The multi-disc clutch assembly comprises an assembly base plate, an internal spline pressure plate and a thrust limit spiral cam, wherein the assembly base plate is connected with the internal spline pressure plate in a mutual embedding manner, a through hole is formed in the middle of the assembly base plate, a group of guiding posts are symmetrically arranged around the periphery of the through hole, and a plurality of outer tooth friction plates and inner tooth lining plates are arranged alternately on the outer side of the assembly base plate in an overlapping manner. A protruding part which extends out of the through hole and round hole parts in clearance fit with the guiding posts are arranged on the internal spline pressure plate. One side of the thrust limit spiral cam is fixed with the assembly base plate, and a cam is arranged at the end part of the other side, and springs are further arranged on the guiding posts and between the internal spline pressure plate and the thrust limit spiral cam. The multi-disc clutch assembly has the advantages of having infinitely increased friction area, good joint surface, fast separation, no impact, stable torque force values and the like after being used for transmitting torques, reducing axial pressure in comparison with the prior art to facilitate smooth and steady mechanical transformation of driving and climbing, and further having higher sensitivity, low cost and more reliable structure.

Description

technical field [0001] The invention relates to the field of electric vehicle driving devices, in particular to a multi-disc clutch assembly used in an electric vehicle self-adaptive automatic torque-increasing energy-saving drive assembly. Background technique [0002] At present, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current to control the speed through the speed control handle or the accelerator pedal, or use the manual mechanical automatic transmission mechanism to realize the speed change. The operation of the handle or the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. In motor vehicles, when the rider does not know the driving resistance, the speed change device is only operated and controlled based on experience, which inevitably has the following problem...
