A split-type adaptive automatic torque-increasing energy-saving drive assembly for electric vehicles

Abstract

The invention discloses a split self-adaption automatic torque adding and energy saving driving assembly for an electric vehicle. The assembly comprises a box, a main shaft, a power input gear, a gear shaft, a clutch assembly, a gear base, a first-grade gear, a transmission unit, a one-way gear and a one-way limiting spiral cam. The split multi-clutch assembly is adopted to transmit the torque, and has such advantages as simple structure, fast assembly, easy machining, capability of infinitely increasing the friction area, good combining surface, fast separation, no impact and stable torque value. Different torque demands are adapted through adjusting the numbers of outer tooth friction pieces and inner tooth lining plates and / or adjusting torque adjusting nuts; and in addition, a thrust limiting spiral cam is pushed by the one-way limiting spiral cam to release the outer tooth friction pieces from the inner tooth lining plates, so that the axial infinite pressurization is limited, the axial pressure of the main shaft is lower than 5000 N, and the damage of a bearing on the main shaft is prevented. The assembly reduces the axial pressure, and has such advantages as stable driving-climbing mechanical conversion and high sensitivity.

Description

technical field [0001] The invention relates to the field of electric vehicle driving devices, in particular to a split-type self-adaptive 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 the following problems: 1. Due to the incre...
