Abstract

The invention relates to a transmission, a power drive system and a vehicle. The transmission comprises a double clutch and a planetary gear mechanism. The double clutch is provided with a first end and a second end, wherein the second end comprises a first shaft and a second shaft, the first shaft of the double clutch is connected to a first moving part of the planetary gear mechanism, and the second shaft of the double clutch is connected to a second moving part of the planetary gear mechanism.

Description

technical field [0001] The present disclosure relates to a transmission, a power drive system and a vehicle. Background technique [0002] The transmission is one of the main assemblies of the car transmission system. The actual use of the car is very complicated, such as starting, idling stop, low or high speed driving, acceleration, deceleration, climbing and reversing, etc., which requires the driving force and speed of the car to be able to change within a considerable range. The output torque and rotational speed of the piston engine widely used at present have a relatively small variation range. Set the transmission in. For new energy vehicles driven by electric motors, although the rotational speed of the electric motor has a large range, in order to match the high-efficiency area of ​​the electric motor, it is necessary to install a transmission in the transmission system in some cases. The transmissions in the prior art are generally complex in structure and rela...
