Problems solved by technology

The traditional multi-speed transmission gearbox has good acceleration performance, and can make the motor work in a high-efficiency working range, improving energy efficiency, but there must be power interruption when shifting gears, and the shifting comfort is poor
Although the single-motor single-stage drive gearbox can realize stepless speed change, its motor cannot always work in the high-efficiency working range, and the energy efficiency is low
In addition, the power of the single-motor drive gearbox is interrupted immediately after the motor fails, and the reliability is not high
The dual-motor power coupling gearbox is improved on the basis of

Abstract

The invention provides a double-motor compact transmission without power failure. The double-motor compact transmission without power failure comprises a motor A, a motor B, a planet row speed reduction device and a mechanical transmission module, wherein the planet row speed reduction device comprises sun gears, planet gears, planet carriers and gear rings; and the transmission module comprises an input shaft A, an input shaft B, four pairs of reduction gears and an output shaft. According to the transmission, through overall planning of the integral space of the motors and the transmission, the spatial size of the transmission is decreased, the light-weight design requirement is achieved, the economy of the transmission is improved, and three matched gears are achieved.

Description

technical field [0001] The invention belongs to the field of power transmission, and in particular relates to a double-motor compact gearbox without power interruption. Background technique [0002] With the increasingly serious environmental pollution and the beginning of energy depletion, it is imminent to reduce vehicle exhaust emissions and improve vehicle energy efficiency. Traditional vehicles that use petroleum derivatives as fuel cannot avoid harmful exhaust emissions, and the congested road conditions in cities make vehicles start and stop frequently, aggravating pollution. In order to solve this problem, pure electric vehicles came into being. Pure electric vehicles use electricity as energy, which has the advantages of energy saving, emission reduction, low noise and high efficiency. [0003] The existing mainstream pure electric drive solutions include: traditional multi-speed transmission, single-motor single-stage drive, dual-motor power coupling drive, etc. ...
