Abstract

The invention discloses an electric vehicle and a power driving device thereof, comprising a driving motor, a speed reducer and a braking mechanism integrated in a hub of the electric vehicle; Drivingmotor is disc motor with axial magnetic field; The reducer is used for transmitting the power on the motor shaft of the drive motor to the rim of the hub; The brake mechanism includes a hub flange fixedly connected to a wheel rim, a brake pad fixed to the hub flange, and a brake caliper for mating with the brake pad, the brake caliper being used for connecting with a brake actuating unit of an electric vehicle. The above pow drive device, By integrating the driving motor, the speed reducer and the braking mechanism into the hub of the electric vehicle, the torque output from the driving motorcan be directly transmitted to the hub only through the speed reducer, thereby avoiding the complicated transmission system, reducing the loss and waste of power in the transmission system and greatly improving the overall transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile drive, in particular to an electric automobile and its power drive device. Background technique [0002] Currently applied to the power drive device of the existing new energy electric vehicle, the torque output by the motor is generally transmitted to the hub through the transmission, the drive shaft, the differential, and the half shaft. The structure in the transmission system is complex, resulting in a large part of the overall transmission efficiency being wasted inside the transmission system, reducing the overall transmission efficiency. [0003] To sum up, how to solve the problem of low transmission efficiency of the power drive device of the electric vehicle has become a technical problem that those skilled in the art urgently need to solve. Contents of the invention [0004] The object of the present invention is to provide an electric vehicle and its power drive device to solve t...
