Abstract

The invention discloses a brake generator of an electric vehicle. The brake generator comprises a stator and a rotor which are embedded in a brake hub, wherein inner ring teeth are arranged at an inner side end of the rotor, outer ring teeth are arranged at an inner side end of the stator, annular frames are arranged at the inner side ends of the stator and the rotor, 3-6 planetary gears meshed with the inner ring teeth and the outer ring teeth are mounted on an outer side of the annular frames, a brake ring is arranged on an outer edge of the annular frame, two brake cylinders fixedly installed on a shaft base and communicated with a brake oil pipe are arranged in the brake ring, each brake cylinder comprises two brake piston rods and an electric brush piston rod, brake shoes are connected with the brake piston rods, and electric brushes corresponding to collector rings at the inner side end of the stator are connected with the electric brush piston rods. The brake generator is advantaged in that the brake generator is reasonable in structure, stable in performance and capable of effectively recovering braking energy.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle manufacturing, and in particular relates to a braking generator for an electric vehicle. Background technique [0002] Since the beginning of the 21st century, energy and the environment have had an increasing impact on human life and social development. Energy-saving and emission-reduction technologies for transportation tools are becoming more and more prominent, energy recovery technology for vehicles has been given full attention, and braking energy recovery systems are widely used in electric vehicles and hybrid vehicles. [0003] At present, the basic principle of braking energy recovery for vehicles with braking energy recovery system is: during the braking process, the motor is used to generate electricity, and at the same time, the electric energy is stored in the power battery to realize the recovery and utilization of braking energy. At present, the structure of the braking en...
