Abstract

The invention discloses a torque auxiliary two-gear mechanical automatic transmission. The transmission comprises an input shaft, an intermediate shaft I, an intermediate shaft II and an output shaft,wherein an auxiliary gear driving gear, a first-gear driving gear and a second-gear driving gear are sequentially arranged on the input shaft, an auxiliary gear driven gear is arranged on the intermediate shaft I, a clutch is arranged between the intermediate shaft I and the intermediate shaft II, a first-gear driven gear, a synchronizer, a second-gear driven gear and a main speed reducer drivinggear are sequentially arranged on the intermediate shaft II, and a differential mechanism and a main speed reducer driven gear are sequentially arranged on the output shaft. According to the transmission, a torque auxiliary gear is added, the problem of power interruption of the two-gear mechanical automatic transmission in the gear shifting process is solved, a dynamic property of an automobileis improved, the torque auxiliary gear can be additionally arranged on the basis of the two-gear mechanical automatic transmission, and the cost is further reduced.

Description

technical field [0001] The invention relates to a torque-assisted two-speed mechanical automatic transmission, which belongs to the technical field of automobile transmissions. Background technique [0002] Pure electric vehicles rely on batteries to provide power and are driven by motors. They have the advantages of zero emissions and low noise, and are an effective way to alleviate current energy consumption and environmental pollution. Different from the internal combustion engine used in traditional vehicles, the drive motor used in pure electric vehicles has the characteristics of wide speed range, constant torque at low speed and constant power at high speed. Due to these excellent characteristics of the drive motor, to a certain extent, clutches and transmissions can be omitted in pure electric vehicles. At present, the power system of pure electric vehicles mostly adopts the scheme of drive motor with fixed speed ratio reducer. This scheme needs to use a high-power ...
