Abstract
The utility model relates to a brake caliper piston which comprises a piston body and a piston cavity which is formed in the front end of the piston body, wherein the piston cavity is of a frustum shape, the inner diameter of the front end of the piston cavity is larger than the inner diameter of the bottom of the piston cavity, an arc groove is formed in the bottom of the piston cavity, an annular groove with a U-shaped cross section is formed in the side wall, close to the front end opening of the piston cavity, of the piston body, and a chromium coating coats the surface of the piston body. The brake caliper piston is simple in structure, the annular groove is formed in the piston body so that the piston body and a transmission assembly can be connected but not to be easily separated, meanwhile, the chromium coating coats the surface of the piston body so that the surface of the piston body is high in rigidity and not prone to rusting, and the service life of the brake caliper piston is prolonged.
Description
Technical field
The utility model relates to a kind of brake caliper piston.
Background technique
Brake piston is the heart of automobile brake, bears mechanical load and the heat load of alternation, is one of worst key components and parts of operating conditions in the brake caliper.The function of piston is to bear fluid pressure, the pressure that brake-fluid provides by brake pump promotes the piston of clamp, piston (internal spiral, can play the effect of limiting displacement) the promotion push rod, push rod pushes friction plate again, friction plate contacts the generation friction and brakes with friction disk, friction disk and integral body generally are positioned front-rear axle.The forward and backward brake caliper piston that the brake system of automobile comprises clamp, cooperates with clamp; And existing brake caliper piston is low working life.
The model utility content
The technical problems to be solved in the utility model provide a kind of simple in structure, connect closely and the brake caliper piston of long service life.
In order to solve the problems of the technologies described above, the utility model provides a kind of brake caliper piston, comprise: piston only, be located at the piston cavity of piston only front end, described piston cavity is taper type, and the piston cavity front inner diameter is greater than the internal diameter of this piston cavity bottom, and the bottom of described piston cavity is provided with one for the arc groove of depositing hydraulic oil, the sidewall of the adjacent front end mouth of described piston only is provided with the circular groove that a cross section takes the shape of the letter U, and this circular groove is used for guaranteeing stable connection between piston only and transmitting assemblies.
The plated surface of described piston only is useful on antirust, wear-resisting chromium coating, and the thickness of chromium coating is 0.1-0.2mm.
Technique effect of the present utility model: brake caliper piston of the present utility model is simple in structure, by at piston only circular groove being set, makes being connected between piston only and transmitting assemblies be difficult for breaking away from; Simultaneously, be coated with chromium coating on the piston only surface, make piston only surface hardness height, be difficult for getting rusty, strengthened the working life of brake caliper piston.
Description of drawings
The utility model is described in further detail below in conjunction with specific embodiment:
Fig. 1 is the structural drawing of brake caliper piston of the present utility model.
Embodiment
Such as Fig. 1-2, the brake caliper piston of present embodiment, comprise: piston only 1, be located at the piston cavity 2 of piston only 1 front end, described piston cavity 2 is taper type, and piston cavity 2 front inner diameter are greater than the internal diameter of these piston cavity 2 bottoms, and the bottom of described piston cavity 2 is provided with one for the arc groove 3 of depositing hydraulic oil, the sidewall of the adjacent front end mouth of described piston only 1 is provided with the circular groove 4 that a cross section takes the shape of the letter U, and this circular groove 4 is used for guaranteeing stable connection between piston only 1 and transmitting assemblies.
The plated surface of described piston only 1 is useful on antirust, wear-resisting chromium coating, and the thickness of chromium coating is 0.1-0.2mm.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
