The purpose of this utility model can be realized by the following technical scheme: a kind of caliper piston, including have interior
The ontology of chamber, one end of the ontology are the open ports being connected with inner cavity, which is characterized in that the outer wall of the ontology has
There are an anti-all rotation structures that can prevent ontology from having enough to meet the need when ontology axial displacement, the inner wall of the inner cavity is equipped with for open ports
Side exhaust air discharge duct, the ontology in one end of open ports side be equipped with several around ontology axis it is circumferentially uniformly distributed
Radiate blind hole.
This caliper will not be had enough to meet the need by anti-all rotation structures in axial displacement braking with piston, to prevent ontology week
The problem of turning avoids ontology from causing to wear to friction plate, extends the service life of friction plate；When braking, in brake fluid inflow
In chamber, air discharge duct facilitates the air in inner cavity to be discharged, and avoids air extrusion and causes brake lag, improves braking effect；It dissipates
The setting of hot blind hole alleviates the weight of ontology, meets light-weight design requirement, and in braking process, and heat is blind by radiating
Hole distributes, and not will lead to the brake fluid temperature at ontology and rises, ensure that braking effect.
In a kind of above-mentioned caliper piston, anti-all rotation structures include the axial extension that body outer wall has
Guide groove, the outer end of the guide groove penetrates through to ontology in the end of open ports side, and the inner end of guide groove extends into ontology
The center of outer wall.
In a kind of above-mentioned caliper piston, the inner end of the guide groove is bonded with rubber pad.Rubber pad plays
Buffer function, when ontology being avoided to reset, guide groove inner end and key block issue the noise collided.
As another situation, in a kind of above-mentioned caliper piston, anti-all rotation structures include that this is external
The guiding rib of axial extension and evagination that wall has, the outer end for being oriented to rib are connected to ontology in the end of open ports side, are oriented to rib
Inner end extend into the center of body outer wall.The pilot hole inner wall of caliper, which has, cooperates sliding slot for guiding rib, to prevent this
Body has enough to meet the need in braking.
In a kind of above-mentioned caliper piston, the inner cavity include into ontology successively deeply arrangement and aperture according to
The quantity of installation cavity one, installation cavity two, installation cavity three and the placed cavity of secondary diminution, the air discharge duct is for multiple tracks and circumferentially equal
Cloth, the air discharge duct axial extension and the inner wall for being connected to both installation cavity two and installation cavity three.It is reasonable in design in this way, just
It is assembled in components such as swivel nuts, air discharge duct is easy to be vented.
In a kind of above-mentioned caliper piston, the ontology is radially through with the gas vent being connected to placed cavity.
When rubber sheet gasket is put into placed cavity, the air between rubber sheet gasket and placed cavity is discharged from gas vent, so that rubber sheet gasket is installed
It is smooth, braking effect will not be influenced because of surface undulation.
In a kind of above-mentioned caliper piston, the radial section of the heat dissipation blind hole is poroid in kidney-shaped.It dissipates in this way
Heat area is more than circular heat dissipation blind hole, and heat dissipation effect is more preferable.
Compared with prior art, the problem of will not having enough to meet the need when this caliper piston deceleration, prevent Wear Friction piece, extends
The service life of friction plate, and the air discharge in inner cavity is smooth, and good heat dissipation effect ensure that braking effect.
