Go out and be in contact with upper friction plate, upper friction plate continues to be pushed up to contacting, compressing with the upper surface of brake disc, then upper friction
Piece stops movement, and with further increasing for oil pressure, axis of the caliper by guider along brake disc moves upwards, to push
Lower friction plate, which is moved upwards, to be contacted with the lower surface of brake disc, compresses, and so far, upper and lower friction plate is compressed with brake disc respectively, from
And clamp brake disc and achieve the purpose that braking, braking effect are efficiently and safe, when not braking, oil pressure reduces, brake disc
Rotation forms a percussion to upper and lower friction plate, and friction plate is caused to generate a gap with brake disc.
Preferably, the guider include be threadedly coupled the guide pin that is fixed on holder and by guide pin with lead
The guide sleeve coordinated to hole, pivot bush unit between the guide sleeve and guide pin.The guide pin being threadedly coupled with holder is used
Direction is moved up and down in limitation caliper, prevents to deviate, is used for the guide sleeve that pilot hole is coordinated another to guide pin
The limit of one end and guiding role can more be used for dust-proof and sealing, guide pin protected not to be damaged.
Preferably, pivot bush unit between the guide sleeve and guide pin.The guide sleeve and guide pin of pivot bush unit, can
When ensureing that plunger shaft oil pressure increases, caliper and holder can be slided up and down smoothly along the direction of guide pin.
Preferably, the holder is fixedly connected by clamp mounting hole with transfer panel or vehicle frame.Be installed on transfer panel or
The supporting structure of vehicle frame is compacter, saves installation space, flexible and convenient to use.
Preferably, the caliper is additionally provided with bleed screw, the inner end of the bleed screw is connected with plunger shaft.It deflates
Screw is for releasing gas extra in caliper.
Preferably, the caliper is equipped with the free interface of clamp, the free interface of clamp is suitable for EPB, IPB interface.
The clamp interface of free interface is suitable for a variety of clamp, and the scope of application is more broad.
Preferably, the guide sleeve is also socketed with rubber stopper.Rubber stopper is for being sealed and preventing to guide sleeve end face
Dirt more can check work and the use state of internal guide pin by opening rubber stopper, be conducive to overhaul and safeguard.
Preferably, the caliper is inner clamp type, the opening of the caliper is towards the outside of brake disc.The caliper of inner clamp type
It is greatly reduced the installation space of brake entirety, structure is compacter.
Therefore, a kind of holder breakaway-element fixed guide pin brake of wheel hub motor of the invention has the following advantages：
First, holder uses breakaway-element, facilitates the installation and removal of clamp, can make caliper under the premise of not tearing holder open along brake disc
Radial direction removes, and is convenient for changing friction plate；Second, using the method for fixed guide pin, guide pin is connected through a screw thread fixation
On holder, guide sleeve is fixed on caliper, and when brake, guide sleeve is motionless, and caliper is moved along guide pin direction, system
Dynamic effect highly effective and safe.
