The invention discloses an automatic transmission for an electric vehicle. The automatic transmission comprises a driving shaft, a first-gear first-level driving gear, a first-gear first-level driven gear, a first-gear second-level driving gear, a first-gear second-level driven gear, a second-gear driving gear and a second-gear driven gear. The first-gear first-level driving gear is arranged on the driving shaft and engaged with the first-gear first-level driven gear. The first-gear second-level driving gear is integrated with the first-gear first-level driven gear and engaged with the first-gear second-level driven gear. The first-gear second-level driven gear and the second-gear driving gear are both coaxial with the driving shaft, and the second-gear driving gear is engaged with the second-gear driven gear. The rotating speeds of rotating components of the automatic transmission are optimized, and the range of the input rotating speed of the automatic transmission is widened; meanwhile, gear shifting time is shortened, and gear shifting quality is improved. In addition, the stress state of the gears is improved, the service life of the gears is prolonged, and transmission noise of the gears is lowered.
Description
technical field [0001] The invention relates to the field of transmissions, in particular to an automatic transmission for electric vehicles and the vehicle. Background technique [0002] Pure electric vehicle (Battery Electric Vehicle, referred to as BEV) refers to a new generation of clean energy vehicles that use vehicle-mounted power supplies as power and drive wheels with motors to drive with minimal impact on the environment. In a single-gear pure electric vehicle, the transmission ratio is fixed, and the output speed can only be controlled simply by changing the motor speed, while the motor speed is controlled by changing the current, which has high requirements on the motor and will affect the motor speed. service life. When the driving motor parameters are determined, the range of output torque and output speed is small, so the maximum speed and climbing performance are limited. Therefore, the two-speed transmission can solve the above-mentioned problems. There a...
