Abstract
The utility model relates to a drum-type brake shoe assembly, in particular to a light truck drum-type brake shoe assembly which mainly solves the problems that due to the fact that in the prior art, an existing brake shoe assembly uses a common friction plate, the existing brake shoe assembly is not environmental-friendly, heavy and short in service life, can damage and abrade dual sheets, and cannot be used in a light truck or others. The light truck drum-type brake shoe assembly comprises a leading shoe (1) and a trailing shoe (2), and is characterized in that the leading shoe (1) and the trailing shoe (2) are shaped like half circular arcs which are mutually symmetrically arranged, the outer surface of the leading shoe (1) and the outer surface of the trailing shoe (2) are respectively fixedly provided with a leading shoe friction plate (3) and a trailing shoe friction plate (4), the leading shoe friction plate and the trailing shoe friction plate are made of metal friction materials, the width of the leading shoe friction plate (3) is smaller than that of the leading shoe (1), and the width of the trailing shoe friction plate (4) is smaller than that of the trailing shoe (2).
Description
Technical field
The utility model relates to a kind of brake shoe for drum brake assembly, 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, and the neck hoof be fixed with respectively from the outer surface of hoof the neck shoe friction plate with from shoe friction plate, lead shoe friction plate, make for few metallic friction material 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.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.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, the length of described neck shoe friction plate is greater than the length from shoe friction plate.
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, and the neck hoof be fixed with respectively from the outer surface of hoof neck shoe friction plate 3 with from shoe friction plate 4, the neck shoe friction plate, make for few metallic friction material from shoe friction plate, the width of neck shoe friction plate 3 is less than the width of neck hoof 1, from the width of shoe friction plate 4 less than the width from hoof 2.The length of neck shoe friction plate is greater than the length from shoe friction plate 4.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.
