Example Embodiment

The present invention will be further explained below in conjunction with the drawings.

As shown in the figure, the present invention includes a stator and a rotor. The stator includes a stator frame 4, a magnet frame 8, a magnet outer holder 7, and a permanent magnet 1. The rotor includes a rotor disc 9 and a flange 2. The rotor disc 9 and the flange 2 pass through a clutch device The clutch device is coaxially connected with the rotor disc 9; the permanent magnet 1 is fixedly connected to the magnet support 8. In order to make the permanent magnet 1 firmly connected, a stator gland 5 and a magnet pressing block 6 are also provided.

The clutch device of the present invention is composed of an air source 24, a cylinder tube 23, a piston 22, a friction plate compression sleeve 18, a return spring 19, a friction steel plate 17, a friction plate 16, a clutch bracket 15, and a rotor bracket 10; the cylinder tube 23 is fixedly connected On the magnet support 8 of the stator, one side ...

Abstract

The invention provides a pneumatic clutch control type permanent magnetism retarder, which relates to a permanent magnetism retarder which comprises a stator and a rotor, wherein, the stator comprises a stator frame, a magnet support, a magnet external holder, a permanent magnet; the rotor comprises a rotor disk and a flange, and the rotor disk and the flange are connected by a clutch device which has the same axis with the rotor disk; the permanent magnet is fixed on the magnet support. Under the normal driving state of a vehicle, the rotor disk does not rotate, does not generate eddy current which hinders the movement of a transmission shaft and does not generate heat. When speed is need to be lowered, the pneumatic clutch starts to work and the rotor disk rotates to realize speed slowing. By utilizing the pneumatic clutch to carry out control, the rotor does not rotate under non-working sate; therefore, the invention has the advantages of requiring no degaussing, no reverse braking torque when in no braking state, energy-saving, large torque moment, high reaction speed, compact structure, safety and long service life.

Description

Pneumatic clutch controlled permanent magnet retarder technical field The invention relates to an automobile retarder, in particular to a permanent magnet retarder. Background technique Automobile retarder is a kind of automobile braking auxiliary device that has been widely used in China in recent years. At present, it is mainly eddy current retarder. Other forms of retarder include hydraulic retarder, permanent magnet retarder, Generator retarder, exhaust brake retarder, etc. Among them, the permanent magnet retarder is gradually favored by users due to its advantages of light weight, no energy consumption, no loss, and maintenance-free. The permanent magnet retarder is an upgraded product of the eddy current retarder, which uses a permanent magnet to replace the coil and iron core used in the eddy current retarder to generate a magnetic field. The rotor disk rotates and cuts the magnetic field lines, thereby generating eddy currents and braking torques to achieve the...
