Double-helix double-overrunning integrated intelligent adaptive electric driving front drive system

Abstract

The invention discloses a double-helix double-overrunning integrated intelligent adaptive electric driving front drive system, which comprises a motor, an adaptive transmission assembly and a front drive power output mechanism, wherein the motor comprises a stator, a rotor and a motor shaft assembly, the motor shaft assembly comprises a motor hollow shaft, a power transmission flange and an outerend mounting flange, the motor hollow shaft is fixed to the inner side of the rotor through the power transmission flange and the outer end mounting flange, and the power transmission flange transmitspower to the front drive power output mechanism through a power output speed reduction assembly and the adaptive transmission assembly in sequence. By the adoption of the technical scheme, the structure is extremely compact, the integration degree is high, the transmission route is short, the transmission efficiency is high, the arrangement of a power mechanism is facilitated, and the influence on dynamic balance of wheels is reduced; through the design of a differential mechanism and related parts, power output of front-engine front-drive layout can be achieved, and the transmission efficiency of the whole transmission axle is high; and through the mounting of the power transmission flange and the outer end mounting flange, the overall balance is better.

Description

technical field [0001] The invention relates to the technical field of electric drive systems, in particular to a double-helix double-transcendence integrated intelligent self-adaptive electric drive precursor system. Background technique [0002] With the increasingly stringent environmental protection regulations, it is the general trend that new energy vehicles represented by pure electric vehicles, motorcycles and tricycles will replace traditional fuel vehicles. [0003] At present, the electric drive systems of automobiles, motorcycles and tricycles powered by pure electricity are composed of two independent parts, the motor and the reduction box (gearbox or transmission box). Not only the transmission efficiency is not high enough, but also the layout of the mechanism is affected. [0004] Moreover, due to the limitations of its transmission structure, the existing electric vehicle is completely controlled by the driver based on experience when the driving resistance ...

Problems solved by technology

[0003] At present, the electric drive systems of automobiles, motorcycles and tricycles powered by pure electricity are composed of two independent parts, the motor and the reduction box (gearbox or transmission box). Not only the transmission efficiency is not high enough, but also the layout of the mechanism is affected.

[0004] Moreover, due to the limitations of its transmission structure, the existing electric vehicle is completely controlled by the driver based on experience when the driving resistance cannot be accurately known during the driving process. Therefore, it is often inevitable that the motor working state and traffic The actual driving conditions of the tool 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. directly affect the battery life

For models with high economic requirements such as electric logistics vehicles, the traditional variable speed transmission structure obviously cannot better meet their use requirements
