Abstract
The utility model relates to a drum-type brake shoe, in particular to a drum-type brake shoe assembly based on an aramid fiber based fiction material. The drum-type brake shoe assembly based on the aramid fiber based fiction material mainly solves the technical problems that in the prior art, a brake shoe is not environment-friendly in use, large in proportion, short in service life capable of damaging friction couple and the like due to the fact that a common friction piece is adopted by the brake shoe assembly. The drum-type brake shoe assembly based on the aramid fiber based fiction material comprises two brake shoes arranged symmetrically and is characterized in that each brake shoe comprises a brake shoe body (1) bent to a round semi-arc shape and an installation edge (2) connected with the middle portion of the brake shoe body. An aramid fiber based friction piece (3) is fixed on the outer surface of the brake shoe body. Through holes (4) are formed in the installation edge.
Description
Technical field
The utility model relates to a kind of brake shoe for drum brake, especially relates to a kind of brake shoe for drum brake assembly based on the aramid fiber base frication material.
Background technique
Automobile drum brake is by hydraulic wheel cylinder brake shoe to be opened, and is pressed on the brake drum, realizes slowing-down brake in the mode of friction.Drum brake also can double as Parking Brake usefulness simultaneously, compares with disk type braker, and the longer service life of friction plate, the vehicle maintenance cost is low.Therefore present economy car all adopts the mode of braking of rousing behind the shroud.Chinese patent discloses a kind of brake shoe assembly (notice of authorization number: CN 201963775U), it comprises the brake shoe weld assembly of semicircle drum type, the week of brake shoe weld assembly is provided with brake lining laterally, the brake shoe weld assembly is provided with wear indicator, it is concordant with the wear limit position of brake lining that one end of wear indicator is suspend shape and its end, and the wear indicator the other end is connected with the sensor of automobile ECU control system; Wear indicator comprises straight bar section, and an end of straight bar section is revealed in the outer end of brake shoe weld assembly and concordant with the wear limit position of brake lining, and the other end of straight bar section is kink shape and its termination section is welded on the brake shoe weld assembly; The kink of wear indicator is " 5 " font, and the afterbody of kink is connected with straight bar section, head is concordant with the profile line of brake shoe weld assembly; Wear indicator is that the tabular stainless steel material bending of bar forms.But this brake shoe assembly adopts general friction plate, more not environmental protection during use, and proportion is heavier, and working life is shorter, can damage friction pair.
The model utility content
The utility model provides a kind of brake shoe for drum brake assembly based on the aramid fiber base frication material, it mainly is to solve the existing brake shoe assembly of prior art to adopt general friction plate, more not environmental protection during use, and proportion is heavier, working life is shorter, can damage the technical problem of friction pair etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Brake shoe for drum brake assembly based on the aramid fiber base frication material of the present utility model, comprise symmetrically arranged two brake shoes, described brake shoe comprises the mounting edge that the brake shoe body that bends to semicircular arc and brake shoe body middle part connect, the outer surface of brake shoe body is fixed with aramid fiber base frication material sheet, has through hole on the mounting edge.Mainly use cruel or other fiber (carbon, pottery etc.) of glass fibre, the cruel fiber of fragrant adoption to be used as reinforcement material without asbestos organic substance type braking material, its performance depends primarily on type and other interpolation mixture of fiber.And the friction factor of aramid fiber base frication material sheet is higher, and wear resistance is better than asbestos friction material, particularly close with semimetal friction material of at high temperature wear resistance.Friction material and hoof face combination also are different from common bonding or riveted joint, and adopt the combination of " sticking+riveting ", the Safety performance of bonded brake shoe is fully ensured, also improved the riveted type Brake shoe lining and easily become flexible and the shortcoming of generation abnormal sound.
As preferably, the both sides of described brake shoe body are provided with 3 pairs of grooves.Utilize groove can change easily aramid fiber base frication material sheet.
Therefore, brake shoe for drum brake assembly of the present utility model adopts aramid fiber base frication material sheet, comparatively environmental protection during use, and light specific gravity, non-corrosive can not damage friction pair, and intensity is higher, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1;
Accompanying drawing 3 is perspective view of the present utility model.
Component, position and numbering among the figure: brake shoe body 1, mounting edge 2, aramid fiber base frication material sheet 3, through hole 4, groove 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the brake shoe for drum brake assembly based on the aramid fiber base frication material of this example, such as Fig. 1, Fig. 2, Fig. 3, comprise symmetrically arranged two brake shoes, brake shoe comprises the mounting edge 2 that the brake shoe body 1 that bends to semicircular arc and brake shoe body middle part connect, the outer surface of brake shoe body is fixed with aramid fiber base frication material sheet 3, has through hole 4 on the mounting edge.The both sides of brake shoe body are provided with 3 pairs of grooves 5.
During use, whole brake shoe for drum brake assembly is encased in the break of automobile and gets final product.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
