Problems solved by technology

Because the speed range of the vehicle is large and the working conditions are complicated, the speed range and torque range of the motor are also very large. Therefore, when selecting a motor, a motor with a larger power is usually selected, so that the speed and torque of the motor cannot be reached under some working conditions. It can be fully utilized and cannot work in the high efficiency area, resulting in waste of power

Abstract

The invention discloses a mechanical motor optimization driving power unit, which comprises a motor power source and a speed-reducing torque-increasing assembly, wherein the motor power source comprises an outer stator fixed on a motor box body and a gear ring inner rotor assembly configuring a permanent magnet, or the motor power source comprises an inner stator fixed on a stator rotating shaft and a sun gear outer rotor assembly configuring a permanent magnet. The optimization, arrangement and combination of the motor rotor (inner or outer rotor), a gear ring (serving as a magnetic yoke of the motor) in a planetary reducer or a sun gear (serving as a magnetic yoke of the motor) are suitable for various operating conditions of an external load according to different speed ratio, so that the motor operates in a high efficiency region, and achieves the effect of saving energy.

Description

technical field [0001] The present invention relates to a drive unit, in particular to a mechanical electrode optimized drive power unit that provides power for traveling transport vehicles and traveling operation machines, and has low operating costs, energy saving and environmental protection. Background technique [0002] At present, in order to implement the national strategy of developing new energy vehicles, the main strategic orientation of new energy vehicles driven by pure electric vehicles, and under the general situation of focusing on the development of pure electric vehicles, various automobile manufacturers have launched different types of vehicles that serve various industries. Various cars. Among them, how to optimize the selection of drive units suitable for various purposes is placed in front of the host manufacturers. At present, most manufacturers use high-power motors with high torque and low speed to directly drive the final drive (drive axle). Because...
