Compact self-adaptive automatic speed change system

Abstract

The invention discloses a compact self-adaptive automatic speed change system, which comprises a motor, a shared speed reduction mechanism, a forward gear speed change system and a transmission axle used for outputting power. The compact self-adaptive automatic speed change system adopting the above technical scheme is novel in structure and easy to implement. Left and right front wheels of a vehicle can be directly driven to rotate by a first transmission shaft and a second transmission shaft, power output of front-engine, front-wheel drive layout is achieved, and the whole transmission axleis high in transmission efficiency and simple, stable and reliable in structure. Moreover, the motor can directly transmit power to a forward gear speed change system and a reverse gear speed change system of the speed changer through cooperation of the shared speed reduction mechanism, the number of parts is reduced, the structure of the speed change system is simplified, the size of the speed change system is reduced, the speed change system is more compact, and meanwhile, the assembling difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a compact adaptive automatic transmission system. Background technique [0002] Due to the limitations of its transmission structure, the existing electric vehicles are completely controlled by the driver based on experience when the driving resistance cannot be accurately known during driving. The actual driving conditions do not match, causing the motor to stall. Especially when the vehicle is under low-speed and heavy-load conditions such as starting, climbing, and headwind, the motor often needs to work at low efficiency, low speed, and high torque, which is likely to cause accidental damage to the motor and increase maintenance and replacement costs. It directly affects the cruising range of the battery. For models with high economic requirements such as electric logistics vehicles, the traditional variable speed transmission structure obviously cannot better meet th...
