Abstract

The invention relates to the related field of transmissions and discloses an electric automobile transmission. The electric automobile transmission comprises an input shaft assembly, wherein the input shaft assembly is in driving connection to an output shaft assembly; the output shaft assembly is connected to a shift selecting mechanism assembly; the input shaft assembly is connected to a driving motor; and the output end of the output shaft assembly is connected to a differential mechanism assembly. By arranging the shift selecting mechanism assembly, two-shift driving of the driving motor can be realized so as to improve the effective working range of the driving motor. By virtue of a shift selecting mechanism, stable shifting can be quickly realized; by virtue of pure electric driving, purposes of simplifying the structure of a transmission device and alleviating the weight of the transmission device are achieved, so that the shifting mechanism is further simplified; by arranging a shift selecting drum, the driving gear and the parking gear can be realized in the same shift selecting mechanism, and various gears can be selected, so that energy integrated optimization of the whole system can be realized in various working conditions.

Description

technical field [0001] The invention relates to the related field of transmissions, in particular to an electric vehicle transmission. Background technique [0002] Existing electric vehicle transmissions are usually divided into two types: single-speed transmission and multi-speed transmission. Among them, in the existing single-speed transmission, the high-efficiency working range of the motor matched with it is narrow, and the driving transmission route is single, which makes it difficult to meet different working conditions. Vehicle requirements at different speeds. However, the gear selection and shift mechanism of the existing multi-speed transmission is complicated in structure, and the gear selection and shift time is long, so it is difficult to meet the requirements of fast gear shifting and ride comfort of electric vehicles. In addition, due to the arrangement of components such as clutches and hydraulic torque converters in traditional power vehicles, there are p...
