Embodiment Construction

[0042] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0043] like Figure 1-5 As shown, the present invention provides a liquid-cooled disk permanent magnet eddy current flexible retarder for a direct push vehicle, which includes: a first stator 110, a guide optical axis 120, a second stator 130, a rotor 140, and a direct push arm 150 , the actuator, the transition frame 210 , the retarder frame 220 and the bearing support block 230 . Both ends of the guide light shaft 120 are fixedly connected to the retarder frames 220 arranged opposite to each other at intervals. The first stator 110 is in the shape of an annular disk, and the first stator 110 is axially disposed on the guide optical axis 120; the second stator 130 has the same structure as the first stator 110 and is similar to the Subs 110 are coaxially spaced on the guide ...

Abstract

The invention discloses a liquid-cooled disc permanent magnet eddy current flexible retarder applied to a direct-push type vehicle. The retarder comprises a guiding optical shaft which is connected with retarder frames which are oppositely arranged at intervals, first and second stators which are arranged on the guiding optical shaft respectively and capable of axially moving along the guiding optical shaft, a rotor coaxially arranged between the first stator and the second stator, a straight pushing arm which is provided with vertically inclined arc-shaped guide chutes and can be supported onthe retarder frames by sliding vertically. Protrusions which are accommodated in the arc-shaped guide chutes are arranged in the peripheries of the first stator and the second stator. The retarder further comprises an actuator which is connected with the straight pushing arm. The actuator drives the straight pushing arm to move to drive the first stator and the second stator to simultaneously beclose to or away from the rotor. The liquid-cooled disc permanent magnet eddy current flexible retarder applied to the direct-push type vehicle, which is provided by the invention, has the advantagesof simple structure, less driving force, being uniformly stressed and good structural stability.

Description

technical field [0001] The invention belongs to the technical field of automotive retarders, in particular to a direct-pushing vehicle liquid-cooled disk permanent magnet eddy current flexible retarder. Background technique [0002] The retarder is a safety auxiliary device for service braking, which applies the braking force to the transmission parts of the vehicle to reduce the speed of the vehicle. At present, the retarders commonly used at home and abroad mainly include hydraulic retarders and eddy current retarders. The hydraulic retarder has a complex structure, long lag time between engagement and separation, and power loss when it is not working; the eddy current retarder has better overall braking effect, but it also has large size, heavy body, power consumption and is affected by the surrounding environment. The disadvantage of large temperature effect is currently only applicable to large commercial vehicles. The permanent magnet retarder forms a magnetic field ...
