Abstract

The invention discloses a three-clutch transmission device for an electric vehicle. The three-clutch transmission device is characterized by comprising an input shaft (1), a K1 clutch (2), a K2 clutch (3), a K3 clutch (4), a first-gear gear (5), a second-gear gear (6), a third-gear gear (7), an output shaft (10), a conduction device (11) and a gear controller, wherein the K1 clutch (2), the K2 clutch (3) and the K3 clutch (4) are respectively connected with the first-gear gear (5), the second-gear gear (6) and the third-gear gear (7); the gear controller automatically controls the output shaft (1) to be switched into different shifts through different clutches; and the output shaft (10) is connected with a gear-shifting gear through the conduction device (11). The three-clutch transmission device for the electric vehicle can be used for the electric vehicle and has the advantages of power gear shifting, short gear shifting time, good gear shifting quality, simple structure, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a three-clutch transmission device for the electric vehicle and the electric vehicle. Background technique [0002] In the development of electric vehicles, the single-stage reducer scheme is mostly used, and the speed regulation characteristics of the motor are used for stepless speed regulation. The single-stage reducer scheme is well applied to small electric vehicles, because small electric vehicles have lower power requirements than traditional internal combustion engine vehicles. However, when expanding the serialization of models and developing the electric drive system of mid-to-high-end cars, it is difficult for the single-stage deceleration scheme to take into account the contradiction between the maximum vehicle speed and the maximum gradient; and if the traditional multi-speed gearbox structure is relatively complicated, and Since the motor has a wider spee...
