Separate multi-piece type clutch assembly

Abstract

The invention discloses a separate multi-piece type clutch assembly. The separate multi-piece type clutch assembly is provided with a spline assembly seat and a thrust limiting spiral cam which sleeve a spindle; a plurality of external tooth friction plates and internal tooth lining plates are arranged on the outer side of the spline assembly seat in an alternately overlapped manner; one end of the trust limiting spiral cam is connected with the spline assembly seat while the other end of the thrust limiting spiral cam is provided with a cam; disc springs which press the external tooth friction plates and the internal tooth lining plates on the spline assembly seat are arranged on one side, which is away from the thrust limiting spiral cam, of the spline assembly seat; and a torque adjusting nut is further arranged at the outer end of each disc spring and is used for adjusting the pressing force of the disc spring. The separate multi-piece type clutch assembly has the advantages of simple structure, speedy assembly, easiness in machining, capability of increasing friction area infinitely, good joint surface, high separation speed, zero impact, stable torque force value and the like; axial infinite pressure boosting is limited effectively; and damage of bearings on the spindle is avoided. To sum up, by the separate multi-piece type clutch assembly, axial pressure is reduced, so that switching of driving climbing machines is stable, and sensitivity is relatively high.

Description

technical field [0001] The invention relates to the field of driving devices for electric vehicles, in particular to a split multi-disc clutch assembly of a split-type self-adapting automatic torque-increasing energy-saving drive assembly for electric vehicles. 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 ...
