Abstract

The utility model discloses a brake caliper assembly, which comprises a shell body, a plunger and a dustproof cover. An inner ring arranged on the opening of the shell body is provided with a circle of a dustproof slot. The dustproof cover is embedded in the dustproof slot, and an inner ring of the dustproof cover is in contact with an outer surface of the plunger. The dustproof cover comprises a rubber body and a metal framework, wherein the metal framework is covered by the rubber body. An end of the exposed metal framework is in contact with the dustproof slot. The brake caliper assembly adopts the technical scheme to avoid a problem that water flows to a side of the dustproof cover and the dustproof slot, reduce a blocking of the plunger, prolong service life of the plunger, and improve safety when an automobile is braked.

Description

Brake caliper assy
Technical field
The utility model relates to a kind of brake caliper assy, especially the forced piston dust-proof cover of brake caliper assy.
Background technique
Figure 1 shows that the no jump ring structure piston dust-proof cover brake caliper assy of tradition, traditional piston dust cover structure mainly contains band jump ring, two kinds of structures of no jump ring.As shown in Figure 2, not 360 degree snap-fit between jump ring 4 and the dust-proof cover 3, do not tighten the position and be easy to into water, as shown in Figure 3, magnitude of interference by rubber parts between no jump ring structure dust-proof cover 3 and the dustproof groove 11 reaches sealing effect, also can't eliminate the water inlet phenomenon and take place, thereby cause between piston dust-proof cover 3 and the rectangular seal 5 the cylinder hole to get rusty generation piston catching phenomenon.
The model utility content
Technical problem to be solved in the utility model provides a kind of brake caliper assy, can improve sealing effect, reduces the piston catching phenomenon.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: brake caliper assy, comprise housing, piston, dust-proof cover, the inboard of the opening of described housing is equipped with a collar dustproof groove, described dust-proof cover embeds described dustproof groove, and the inner ring of described dust-proof cover contacts with described outer surface of piston, and described dust-proof cover comprises rubber body and metal frame, described metal frame is wrapped up by described rubber body, and the end of described metal frame exposed parts contacts with described dustproof groove.
As preferably, be interference fit between described dust-proof cover and the described dustproof groove.
As preferably, described outer surface of piston is equipped with a circle draw-in groove, and the inner ring of described dust-proof cover is provided with dop, and described dop snaps in the described draw-in groove.
The utility model has been owing to adopted technique scheme, eliminated the intake generation of phenomenon of dust-proof cover and dustproof groove one side, reduced the piston catching phenomenon, prolonged piston working life, the Security when having improved automobile brake.
