Rear drive assembly of mechanical intelligent self-adaptive automatic gearbox

Abstract

The invention discloses a rear drive assembly of a mechanical intelligent self-adaptive automatic gearbox, which comprises the gearbox and a power device which are arranged on a vehicle frame, wherein the power device outputs power through a transmission shaft of the gearbox and is backwards in transmission connection with a differential mechanism through a universal joint; and the differential mechanism is in transmission connection with rear wheels of a vehicle. The rear drive assembly has all advantages of the existing cam self-adaptive automatic gearbox, adopts a pre-arranged or centrally-arranged rear drive structure and is combined with a transmission structure of a spiral cam pair, and the radial size of the rear drive assembly is further reduced, so the volume is decreased, the adaptability is high and the service life is greatly prolonged; and the spiral structure transmits steadily, is stressed evenly and has incomparable stability and smoothness, so the work efficiency is further improved, better energy-saving and consumption-reducing effects are achieved, vehicle emissions are greatly controlled, the rear drive assembly is more suitable for being used on pure electric vehicles and tricycles, and the dynamic performance, the economical performance, the driving safety performance and the comfortable performance of the vehicles are greatly improved.

Description

technical field [0001] The invention relates to a drive assembly of a motor vehicle, in particular to a rear drive assembly of a mechanical intelligent self-adapting automatic transmission. Background technique [0002] In the prior art, tricycles or automobiles basically directly control the throttle or current to control the speed by manual or accelerator pedal, and the operation of the handle or accelerator pedal depends entirely on the driver's operation, often resulting in a mismatch between the operation and the driving conditions , causing the motor or engine to run unstable and stalled. [0003] When the motor vehicle is operated and controlled by the rider only based on experience without knowing the driving resistance, the following problems inevitably exist: 1. When starting, going uphill and with a large load, the motor or motor is forced to The engine speed drops to work in the low efficiency area. 2. Since there is no mechanical transmission to adjust the tor...

AI Technical Summary

Problems solved by technology

[0007] In view of this, the object of the present invention is to provide a rear drive assembly of a mechanically intelligent self-adaptive automatic transmission, which can not only adapt to changes in driving resistance without cutting off the driving force, but also automatically perform gear shifting, and solve the problem of motor torque-rotational speed. Small changes can not meet the problem of road use under complex conditions. It has good stability, further improves work efficiency, has better energy saving and consumption reduction effects, reduces volume, and further improves service life. It is more suitable for electric vehicles and other vehicles. And it has good adaptability to heavy-duty electric vehicles
