Abstract

A permanent magnet retarder, with a bracket, a stator, a rotor drum and a drive shaft; the stator has an end plate and an inner ring cage and an outer ring cage fixed on the end plate, and the rotor drum has an end plate And the shaft sleeve, inner ring body and outer casing fixed on the end plate; the transmission shaft is fixedly connected with the shaft sleeve of the rotor drum, and two symmetrically distributed fixing seats are fixed on the outer surface of the end plate of the stator, each fixing seat A push-pull rod is connected to the top of the bracket, and an electric push rod is fixed on one of the fixed seats on the top plate of the bracket, and the electric push rod is connected with the corresponding push-pull rod; The outer ring cage of the stator can be inserted into the annular cavity between the inner ring body and the outer shell of the rotor drum. The electric push rod of the present invention controls the overlapping degree of the stator and the rotor drum, that is, it can realize the stepless control of the permanent magnet retarder, and the multi-layer overlapping of the stator and the rotor can greatly increase the braking torque.

Description

Technical field [0001] The invention relates to a permanent magnet retarder. Background technique [0002] When the car is decelerating or going down a long slope, the retarder can be activated to smoothly decelerate and avoid the wear and heat caused by using the brake. The permanent magnet retarder uses permanent magnets for excitation. The magnetic field generated by the permanent magnet is limited, so the generated braking torque is small, and can not provide different braking torques; and because of the use of permanent magnet rare earth materials, the heat dissipation effect is poor. Chinese Patent Publication No. CN101009456A (Patent Application No. 200710019389) invention application discloses a permanent magnet retarder involving stepless adjustment of braking torque. It includes a stator and a rotor, and also includes at least one elastic mechanism. The rotor is placed on the outside of the stator. The stator is composed of a magnet holder, a magnet bracket, a stator ...
