Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] control figure 1 —3. The dual-disc permanent magnet retarder for vehicles of the present invention is mainly composed of a rotor and a stator, and the rotor can rotate around the center of the stator. The rotor is composed of two left and right rotor discs 3 and a rotating shaft 11. The left and right rotor discs 3 are symmetrically placed on both sides of the stator and installed on the rotating shaft 11. The rotor disc 3 is connected with the automobile transmission shaft through a screw hole 9. The rotor disc 3 is provided with cooling fins 4, and the rotating shaft 11 is connected with the rotor disc 3 through a spline 10, and the two ends of the rotating shaft 11 are fixed with nuts. A third air gap adjusting gasket 12 is provided between the rotor disk 3 and the rotating shaft 11, and the air gap between the rotor disk 3 and the stator is ...

Abstract

The invention discloses a double disc type permanent magnet retarder for a vehicle. The double disc type permanent magnet retarder for the vehicle is mainly composed of a rotor and a stator, the rotor is composed of a left rotor disc, a right rotor disc and a rotary shaft. The stator is mainly composed of a magnetic pole piece support provided with magnetic pole pieces and a permanent magnet body support provided with permanent magnet bodies. The permanent magnet body support and the magnetic pole piece support are arranged between the left rotor disc and the right rotor disc in parallel, the permanent magnet body support is installed on a hollow shaft through a sliding bearing, the hollow shaft is installed on the rotary shaft through a rolling bearing, the magnetic pole piece is installed on the hollow shaft and is fixedly connected with a bearing cover of the rolling bearing, the outer side edge of the magnetic pole piece support is connected with an air cylinder component, a rocker arm is arranged on the outer side edge of the permanent magnet body support, and the rocker arm is driven by the air cylinder component. The double disc type permanent magnet retarder for the vehicle is simple in structure, exquisite in design and low in manufacturing cost, and the brake torque can be adjusted through the control over the swinging angle of the permanent magnet body support.

Description

technical field [0001] The invention relates to an auxiliary brake device for automobiles, in particular to a double-disc permanent magnet retarder for vehicles, which is axially excited by NdFeB permanent magnets, and two left and right rotating rotor disks generate braking torque. Background technique [0002] The permanent magnet retarder for vehicles is a new type of non-contact driving auxiliary braking device, which is mainly installed on the transmission system of the vehicle. When the vehicle is driving down a long slope in a mountainous area, long-term frictional braking will heat up the wheel hub, resulting in thermal degradation of the braking system, reduced braking torque, or even failure, which seriously affects the driving safety of the vehicle in mountainous areas. The retarder acts the braking torque on the transmission system, and plays a role in reducing and stabilizing the vehicle speed without using or using less friction brakes, reducing the frequency a...
