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-clutch three-speed transmission which is mainly applied to an electric automobile. The transmission can provide three forward gear ratios, and the problem that driving force and the speed cannot be both considered in an electric automobile with the single reduction ratio is solved. The double-clutch three-speed transmission comprises a first clutch, a second clutch, an input shaft, a first output shaft, a second output shaft and a gear selecting assembly. The input shaft and the first output shaft select a first variable-speed gear pair or a third variable-speed gear pair through the gear selecting assembly to transmit motion and torque, and the input shaft and the second output shaft transmit motion and torque through a second variable-speed gear pair.

Description

technical field [0001] The invention relates to the automobile transmission technology, in particular to a dual-clutch three-speed transmission. Background technique [0002] The driving conditions of the car are complex and changeable, and the driving resistance and driving speed vary greatly. The rolling resistance and wind resistance when moving forward at a constant speed on a straight road are small, but the climbing resistance or acceleration resistance is very high when climbing a steep slope or accelerating rapidly. Large, the required driving force is several times or even ten times different. In addition, the car must meet the requirements of special road sections to crawl slowly at a speed of several thousand kilometers per hour or even slower, and at the same time, it must be able to drive at a speed of more than one hundred kilometers per hour or even faster. Driving at a fast speed requires the drive wheels to run in a fairly wide range of speeds. Gasoline engi...
