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 three-speed transmission provided with two input shafts. The three-speed transmission provided with the two input shafts is mainly used for electric automobiles. The transmission can provide three advancing gears, and the problem that an electric automobile only with a single-stage reduction ratio cannot take the driving force and the speed into consideration is solved. The three-speed transmission provided with the two input shafts comprises a planetary gear row, gear selecting assemblies, the first input shaft, the second input shaft and the like. The two input shafts are connected with two sets of motors correspondingly. Through the two gear selecting assemblies, a sun gear or a gear ring of the planetary gear row is used as an input component, and a planetary carrier is used as an output component so that three different gear ratios can be obtained. The three-speed transmission provided with the two input shafts has the advantages of being compact in structure, low in weight, high in transmission efficiency, reliable in transmission and the like and is particularly suitable for the electric automobiles.

Description

technical field [0001] The invention relates to the automobile transmission technology, in particular to a double-input-shaft three-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 c...
