Abstract

The invention provides an energy recovery device, and relates to the technical field of energy recovery. The energy recovery device comprises a hub motor, a case and a suspension device, an electric power storage device, a controller and a rectifier are fixedly arranged at the inner end of the case, the case is fixedly connected with the hub motor through the suspension device, the hub motor comprises a wheel hub, a first bearing seat, a second bearing seat, a rotor mounting frame, a stator mounting frame, a motor stator, a motor rotor, a rotating shaft, a magnetic encoder, an integrated control unit, a brake disc and a brake caliper, a rear bearing is arranged at the inner end of the first bearing seat, a front bearing is arranged at the inner end of the second bearing seat, the rotatingshaft is rotationally arranged at the inner ends of the front bearing and the rear bearing, and the rotor mounting frame is arranged between the first bearing seat and the wheel hub. By using the device, the energy generated in the braking or downhill process of the integrated motor of the electric automobile can be effectively recycled, and the recycling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to an energy recovery device. Background technique [0002] In order to protect the environment and save energy, the society is currently vigorously developing electric vehicle technology. Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Electric vehicles are mainly divided into three types. Category: battery electric vehicle (BEV), hybrid electric vehicle (HEV), fuel cell vehicle (FCEV). [0003] In order to better save energy, the current electric vehicles mostly use the hub motor with integrated electric power generation. The motor consumes power when accelerating, and the motor generates power when braking or going downhill. The working principle of the hub motor is a permanent magnet synchronous motor. "Wheel motor, hub motor" refers to t...
