Problems solved by technology

[0008] After checking and investigation, at present, there is no domestic manufacturer of this kind of second-speed automatic transmission for new energy vehicles. At present, the motor-driven powertrain of pure electric vehicles in China uses a deceleration mechanism with a fixed speed ratio, which does not fully meet the characteristics of the motor.

Abstract

The invention belongs to the technical field of new energy automobiles and relates to an automobile gearshift mechanism, in particularly to a wet type two-gear automatic transmission. The wet type two-gear automatic transmission comprises a rear outer casing; a front outer casing is connected to the rear outer casing; an input end of the rear outer casing is provided with a power oil pump; one end inside the rear outer casing, which is opposite to the power oil pump, is provided with a wet type variable speed changing clutch; an output end of the power oil pump is connected with a power input shaft; power of the power input shaft is input to the wet type variable speed clutch; power of the wet type variable speed clutch is output to the power output shaft; the power input shaft is supported to the rear outer casing in a rotary mode; one end of the power input shaft is extended to the front outer casing; the power input shaft extends to the front portion of the front outer casing and is connected with a motor connecting disc; the power output shaft is supported to the rear outer casing in a rotary mode; the power input shaft and the power output shaft are arranged in a parallel mode. The wet type two-gear automatic transmission is small in size, light in weight, high in rated rotation speed and large in rated driving torque.

Description

technical field [0001] The invention belongs to the technical field of new energy automobiles, and relates to an automobile shift mechanism, in particular to a wet-type second-speed automatic transmission. Background technique [0002] As early as the "Eighth Five-Year Plan" in my country, electric vehicles were listed as key research and development projects. During the "Ninth Five-Year Plan", electric vehicles were listed as major scientific and technological industrial projects. Adhere to the "three vertical and three horizontal" R & D layout, "Eleventh Five-Year Plan" and set up "863 plan" energy-saving and new energy vehicles major projects to continue to fund the research and development, application and promotion of new energy vehicles. [0003] At present, compared with foreign models of the same type, domestic electric vehicles still have problems such as compact vehicle structure and loose coordination between various assemblies. In order to solve these problems, m...
