Wheel side retarder for trailer/semi-trailer and control method thereof

Abstract

The patent of the present invention relates to a wheel side retarder for a trailer / semi-trailer and a control method thereof, including a stator, a rotor disc, a control mechanism and a drive mechanism. The stator is composed of several permanent magnets, which are divided into inner and outer rings and are evenly arranged along the circumferential direction of the magnet fixing bracket; the rotor disc and the half shaft of the wheel are fixedly connected by a flange; the control mechanism is composed of a connecting sleeve, a guide disc, and a large gear; the driving mechanism is driven by a motor. The pinion gear is fixed on the output shaft, and the pinion gear meshes with the large gear in the control mechanism to output the rotational motion of the motor to the guide disc; by controlling the angular displacement of the motor, the control of the output braking torque of the wheel retarder is realized. The trailer / semi-trailer wheel side retarder of the present invention has simple structure and good control performance, overcomes the disadvantage of traditional wheel side retarder that consumes a large amount of on-board electric energy during use, saves vehicle energy consumption, and is beneficial to wheel side retarder Large-scale promotion and use of retarding devices.

Description

technical field [0001] The patent of the invention relates to the field of automotive brake-by-wire, in particular to a wheel side retarder for a trailer / semi-trailer. Background technique [0002] At present, when the vehicle is braked with friction brakes, the braking response time of the vehicle is relatively slow, and high-intensity braking will cause a large degree of wear on the brake shoes, and the braking efficiency of the friction brake will decrease with the continuous braking time. These shortcomings can be effectively remedied after the wheel retarder is installed. When the vehicle is in non-emergency working conditions such as high speed and long slopes, the wheel side retarder is first used to reduce the speed of the car, and then the friction brake is used to brake and stop. Since the wheel retarder bears a considerable part of the braking load, it can effectively reduce the number of times the friction brake is used, reduce the temperature of the friction br...
