Abstract

The invention provides an electric bridge system, comprising: a first driving motor for driving vehicle hubs to rotate; a planet gear mechanism, wherein an input shaft of the planet gear mechanism isconnected with an output shaft of the first driving motor, and the planet gear mechanism is used for driving the hubs to rotate; a driving mechanism connected with the planet gear mechanism and used for selectively driving the planet gear mechanism to rotate so as to adjust the speed of the hubs. The first driving motor cooperates with the planet gear mechanism to transmit power; the driving mechanism selectively drives the planet gear mechanism to rotate so as to selectively increase the output speed of the planet gear mechanism; the first driving motor and the driving mechanism cooperate with the planet gear mechanism so that the output speed of the planet gear mechanism is adjusted under fixed tooth ratio to adjust vehicle speed; therefore, the requirement on highest speed of the motoris lowered.

Description

technical field [0001] The invention relates to the technical field of drive, in particular to an electric drive axle system. Background technique [0002] The drive system of new energy vehicles generally consists of an electric drive axle composed of a motor and a reducer. The motor converts electrical energy into mechanical energy to provide power for the vehicle, and then reduces the speed of the motor through the reducer, and at the same time amplifies the output torque of the motor to achieve the effect of deceleration and torque increase, so that the vehicle can run within a certain speed range and under a certain driving force . At present, the electric drive system in new energy vehicles is generally composed of a motor and a reducer with a fixed gear ratio. In order to meet the maximum speed of the vehicle, the motor speed needs to be adjusted within a wide range. The high-power motor is matched with the whole vehicle. [0003] However, the adjustment of the spe...
