Abstract
The utility model discloses a piston dustproof cover for an automobile disc brake caliper, which comprises a barrel consisting of a framework and a rubber sleeve formed through vulcanization integration and coated outside the framework. The piston dustproof cover is characterized in that glue overflow pores are distributed on the lateral wall of the framework, an annular groove is arranged on the rubber sleeve at the bottom portion of the inner wall of the framework, the rubber sleeve portion at the upper end of the inner wall of the framework is composed of annular rings folded in wave folding form, the folding position of each annular ring is in the shape of an arc groove, and the bottom portion of the folding position is connected with a hemispherical annular projection. An annular spherical hoop is connected to the lower edge of the annular ring on the innermost side. The piston dustproof cover resolves the problems of framework exposure corrosion and assembly stickiness at the bent position of rubber bodies caused by framework external positioning, thereby increasing service life of products, and saving the treatment cost of exposure corrosion of the barrel-type framework.
Description
Technical field:
The utility model relates to a kind of automobile brake component, relates in particular to a kind of automobile disk-type braking pincers piston dust-proof cover.
Background technique:
The automobile disk-type braking pincers are when braking work, and friction plate compressed brake disc along piston in wheelcylinder piston promoted, and interior friction plate is again along the piston playback, so piston and dust-proof cover thereof directly influence the kinematic dexterity of brake calipers and the sensitivity of braking after the end of braking.Similar products are to adopt injection molding technique abroad, there is the skeleton positioning groove at position, product skeleton outer, the shortcoming that this technology is made product is: molding cycle is long, production efficient is low, the cost height, and the skeleton positioning groove is left in product skeleton outer, and skeleton is exposed in the air, very easily corrosion.
The content of model utility:
The utility model purpose is in order to remedy the defective of prior art, a kind of automobile disk-type braking pincers piston dust-proof cover is provided, the skeleton exposure corrosion problem and the rubber body bending part that have thoroughly solved skeleton outside location generation assemble the problem that is clamminess, improved the working life of product, saved cylindrical skeleton and exposed antirust processing cost.
The utility model is achieved through the following technical solutions:
A kind of automobile disk-type braking pincers piston dust-proof cover, include cylindrical shell, described cylindrical shell is made up of the skeleton rubber sleeve through the sulfuration one outer with being coated on skeleton, it is characterized in that: described skeleton sidewall is distributed with the glue aperture that overflows, on the rubber sleeve of described inboard wall of skeleton bottom annular groove is arranged, the rubber sleeve part of described inboard wall of skeleton upper end is made up of the folding annular ring of waveform, and the burst of described annular ring is a circular arc ditch shape, and the burst bottom is connected with hemispherical annular protrusion; Described being positioned at is connected with annular spherical hoop on the most inboard annular ring lower edge.
The edge of described cylindrical skeleton is coated fully by rubber, and the assembling back skeleton can not be exposed in the air.
The utility model adopts compression molding technology, solved injection technique to equipment requirement height, the fabricating cost height, the problem that manufacturing efficiency is low, the cylindrical skeleton sidewall design has equally distributed excessive glue aperture, the fluid sizing material overflows fast and fills up the entire die die cavity in the time of effectively guaranteeing to vulcanize, and can prevent that also skeleton is subjected to the extrusion-deformation of fluid sizing material when avoiding product to lack material.
The utility model has the advantages that: the utility model has improved the sealing characteristics of brake caliper piston, solved the skeleton exposure corrosion problem that the outside location of skeleton produces, the rubber body bending part assembles the problem that is clamminess, and in the working life of having improved product, has saved cylindrical skeleton and has exposed antirust processing cost.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model A-A structure sectional view.
Embodiment:
A kind of automobile disk-type braking pincers piston dust-proof cover, include cylindrical shell, described cylindrical shell is made up of skeleton 1 and the rubber sleeves 2 through the sulfuration one that are coated on outside the skeleton dual-side 3, skeleton 1 sidewall is distributed with the glue aperture 6 that overflows, on the rubber sleeve of described skeleton 6 inwalls bottom annular groove 5 is arranged, rubber sleeve 2 parts of described skeleton 1 inwall upper end are made up of the folding annular ring 4 of waveform, and the burst of described annular ring 4 is a circular arc ditch shape, and the burst bottom is connected with hemispherical annular protrusion 7; Described being positioned at is connected with the spherical hoop 10 of rubber annular on the most inboard annular ring lower edge.Rubber sleeve 2 external diameter positions are stuck on the draw-in groove of braking clamp body 8 inwalls, and rubber sleeve 2 endoporus positions are entrenched on the draw-in groove of piston 9 cylindricals.
