Abstract

The invention discloses a double-clutch planetary electric differential mechanism, and relates to the technical field of vehicles. The double-clutch planetary electric differential mechanism comprises a main differential mechanism, a double planet wheel planet row, a left torque distribution planet row, a right torque distribution planet row, a deceleration planet row, a power clutch, a torque distribution clutch and a motor. Switching of different working modes is realized by controlling the connection and the disconnection of the torque distribution clutch and the power clutch. The double-clutch planetary electric differential mechanism is compact in structural design; the defect of low passage capacity, on a damaged pavement, of a vehicle is overcome; directional distribution of the output torque of a drive shaft is realized; the problems of poor acceleration performance and limited climbing capability of the vehicle in the low speed region are solved; the power performance and the economic performance of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a double-clutch planetary electric differential. Background technique [0002] As one of the key components of a car, the differential can make the left and right drive wheels roll at different angular velocities when the car is turning or driving on uneven roads, thereby ensuring pure rolling motion between the drive wheels on both sides and the ground. Conventional differentials usually distribute the torque equally between the two driving wheels. When the driving wheel on one side of the car is on a road with a low adhesion coefficient, such as ice, snow or muddy roads, the driving torque of the wheel on this side is very small, and the differential is averaged. The nature of distributing torque tends to make the opposite drive wheel stand still. The limited-slip differential can solve this problem to a certain extent, but it requires a reliable and high-precision differe...
