Problems solved by technology

The transmission is ingeniously conceived, and can obtain a low gear with a large gear ratio and a direct gear with a small gear ratio, which improves the power performance of the electric vehicle, but the gear shift speed difference of the gear is too large, which inevitably affects the gear shift quality, and Electric vehicle transmissions with only two gear ratios cannot well meet the complex and changeable power demands of vehicles

Abstract

The invention provides a double-input-shaft four-speed transmission which is mainly applied to electric vehicles and hybrid electric vehicles. The transmission can provide four advancing gears. The problem that an electric vehicle with the only single-level reduction ratio cannot give consideration to driving force and speed is solved. The transmission comprises a planetary gear row, gear selecting assemblies, a first input shaft, a second input shaft, an output shaft and the like. The two input shafts can be connected with two motors correspondingly. Different components of the planetary gear row are connected with the input shafts through the gear selecting assemblies so that reduction ratios with different speed ratios can be achieved.

Description

technical field [0001] The invention relates to the automobile transmission technology, in particular to a dual-input-shaft four-speed transmission. Background technique [0002] The driving conditions of the car are complex and changeable, and the driving resistance and driving speed change greatly. When accelerating rapidly and climbing a steep slope, a very large driving force is required to overcome the driving resistance. When driving at high speed, a high driving wheel speed is required. Electric vehicles driven by advanced single-stage reduction gearboxes often take care of one thing and lose another, and it is difficult to meet the complex and changeable power requirements of some working conditions that require a large driving force and some working conditions that require high speed. [0003] Some electric vehicles use more powerful motors to improve the vehicle's dynamic performance with greater reserve power. However, high-power motors directly increase the cost...
