Abstract
The utility model relates to a drum-type brake shoe assembly, in particular to a light truck drum-type brake shoe assembly. The light truck drum-type brake shoe assembly aims to resolve technical problems that in the prior art common friction plates are adopted by an existing brake shoe assembly, environmental protection can not be achieved when the existing brake shoe is used, proportion is large, service life is short, friction objects can be damaged, and can not be used in a light truck. The light truck drum-type brake shoe assembly comprises a leading shoe (1) and a trailing shoe (2). The light truck drum-type brake shoe assembly is characterized in that the leading shoe (1) and the trailing shoe (2) are semi-circular arcs which are arranged perpendicular to each other, a leading shoe friction plate (3) and a trailing shoe friction plate (4) are respectively arranged on the outer surface of the leading shoe (1) and the outer surface of the trailing shoe (2), and the length of the leading shoe friction plate is larger than that of the trailing shoe friction plate.
Description
Technical field
The utility model relates to a kind of brake shoe for drum brake, especially relates to a kind of pick up truck brake shoe for drum brake assembly.
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, can't be used in pick up truck.
The model utility content
The utility model provides a kind of pick up truck brake shoe for drum brake assembly, it mainly is to solve the existing brake shoe assembly of prior art to adopt general friction plate, more not environmental protection during use, proportion is heavier, working life is shorter, can the damage friction pair, can't be used in the technical problem of pick up truck etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Pick up truck brake shoe for drum brake assembly of the present utility model, comprise the neck hoof with from hoof, described neck hoof be mutual symmetrically arranged semicircular arc from hoof, the neck hoof, from the outer surface of hoof be fixed with respectively the neck shoe friction plate, from shoe friction plate, wherein lead the length of shoe friction plate greater than the length from shoe friction plate.Friction plate 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 width of described neck shoe friction plate is less than the width of neck hoof, from the width of shoe friction plate less than the width from hoof.The width of friction plate is less than the neck hoof, from the width of hoof, prevent friction plate extend to the neck hoof, outside hoof, impact is used.
As preferably, described neck hoof, be provided with groove from the both sides of hoof.By groove can be easily renewal of facing renewal more.
Therefore, brake shoe for drum brake assembly of the present utility model can be applied on the pick up truck, 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 left brake shoe of the utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1;
Accompanying drawing 3 is a kind of structural representations of the utility model right braking hoof;
Accompanying drawing 4 is B-B cross-sectional view of Fig. 3.
Component, position and numbering among the figure: the neck hoof 1, from hoof 2, the neck shoe friction plate 3, from shoe friction plate 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 pick up truck brake shoe for drum brake assembly that this is routine, such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, comprise neck hoof 1 with from hoof 2, the neck hoof be mutual symmetrically arranged semicircular arc from hoof, neck hoof 1, from the outer surface of hoof 2 be fixed with respectively neck shoe friction plate 3, from shoe friction plate 4, wherein lead the length of shoe friction plate greater than the length from shoe friction plate.The width of neck shoe friction plate is less than the width of neck hoof, from the width of shoe friction plate less than the width from hoof.The neck hoof, be provided with groove 5 from the both sides of hoof.
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.
Claims (3)
1. pick up truck brake shoe for drum brake assembly, comprise the neck hoof (1) with from hoof (2), it is characterized in that described neck hoof (1) and be mutual symmetrically arranged semicircular arc from hoof (2), neck hoof (1), from the outer surface of hoof (2) be fixed with respectively neck shoe friction plate (3), from shoe friction plate (4), wherein lead the length of shoe friction plate greater than the length from shoe friction plate.
