Periphery and arc-shaped bent plate and the brake block for being fixed on bent plate outer surface, existing bent plate are using sheet metal mostly
Punching shaping is bent, in forming process, processes bent plate according to the radian of design requirement, but due to stress problem, assembling
When, the radian of bent plate is difficult accurately preferably to cooperate with web and brake block, influence installation accuracy, meanwhile, bent plate it is strong
It spends poor, causes the stability for the brake block for being fixed on its outer surface also poor.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model be intended to provide a kind of heavy vehicle brake it is total
At can improve the intensity of bent plate, overcome the problems, such as the problem of the difference of assembly precision caused by bent plate stress.
To achieve the above objectives, the present invention adopts the following technical solutions:
The brake assembly of heavy vehicle, including brake backing plate, two brake-shoes being oppositely arranged, two brake-shoe
One end is rotatably connected on brake backing plate, the other end is respectively formed a free end, and brake-shoe includes web, is located at outside web
The bent plate of periphery and the brake block for being fixed on bent plate outer surface, the inner surface of bent plate are provided with multiple first convex ribs and second
Convex ribs, multiple first convex ribs extend along the length direction of bent plate, and multiple second convex ribs extend along the width direction of bent plate, and the
One convex ribs and the intersection of the second convex ribs make multiple first convex ribs and the second convex ribs constitute reticular structure.
The outer peripheral edge of web is provided with the recess for the insertion of the second convex ribs.
The section semicircular in shape of first convex ribs and the second convex ribs.
Brake block is fixedly connected by multiple rivets with bent plate.
There are two pivot pins, one end of the web of two brake-shoes is articulated on two pivot pins respectively for setting on brake backing plate, and
Web is simultaneously rotatably assorted with pivot pin, and a tension spring is mounted between the web of two brake-shoes.
The utility model has the beneficial effects that:
Compared with the prior art, the utility model improves assembly precision, during brake operation, due to bent plate with
Fit-up gap between brake block and web is small, the time of the brake response of shortening, improves the performance of brake simultaneously, and
One convex ribs and the second convex ribs can increase the integral strength of bent plate, and effectively reducing brake, bent plate occurs in use
A possibility that deformation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In the following, being further described in conjunction with the drawings and specific embodiments to the utility model:
As shown in Figure 1, a kind of brake assembly of heavy vehicle for the utility model comprising brake backing plate 10,
Two brake-shoes, two brake-shoes are oppositely arranged and are located at the two sides of brake backing plate 10;One end of two brake-shoes is equal
Be rotatably coupled on brake backing plate 10, the other end is respectively formed a free end, particularly, two brake-shoes include abdomen
Plate 20, bent plate 21 and brake block 22, wherein bent plate 21 is arc-shaped and is weldingly fixed on the outer peripheral edge of web 22, and brake block 22 is then
It is fixed on the outer surface of bent plate 21, two pivot pins 30 parallel to each other, the web of two brake-shoes are set on brake backing plate 10
22 upper end is articulated in respectively on two pivot pins 30, and web 20 and pivot pin 30 rotatably cooperate;In the utility model, curved
Multiple first convex ribs 211 and the second convex ribs 212 are provided on plate 21, the first convex ribs 211 and the second convex ribs 212 are to be located at bent plate
21 inner surface can be through the stamping process, by the outer surface punching press bent plate 21 of bent plate 21, in the inner surface shape of bent plate 21
At, multiple first convex ribs 211 are the length direction extensions along bent plate 21, and multiple second convex ribs 212 are then along bent plate 21
Width direction extends, and the first convex ribs 211 and the second convex ribs 212 intersect, i.e., multiple first convex ribs 211 and the second convex ribs
212 bent plate 21 inner surface form a reticular structure.Brake block 22, which can be, is fixed on bent plate 21 by multiple rivets 23
On.
First convex ribs 211 and the second convex ribs 212 are set on bent plate 21 in the utility model, bent plate 211 can be enhanced in length
The bending resistance in direction and width direction is spent, and after forming according to design requirement, the first convex ribs 211 and the second convex ribs
212 can eliminate influence of the stress to bent plate 21, spring back bent plate 21 will not, ensure that the assembly progress of bent plate 21, make
The radian of bent plate 21 can adapt to the radian of 22 inner surface of radian and brake block of 20 outer peripheral edge of web, improve assembly essence
Degree, during brake operation, since the fit-up gap between bent plate 21 and brake block and web is small, the braking of shortening is anti-
The time answered improves the performance of brake simultaneously, and the first convex ribs 211 and the second convex ribs 212 can increase the entirety of bent plate 21
Intensity effectively reduces brake bent plate a possibility that deformation occurs in use.
In order to be positioned while being reduced fit clearance in assembly, the outer peripheral edge of above-mentioned web 20 is also set up
There are multiple recess 201, multiple second convex ribs 212 on bent plate 21 arrange in for 201 embedded in multiple, in this way, increasing curved
The contact area of plate 21 and web 20 then increases the bonding area of the two.First convex ribs 211 and the second convex ribs 212
Cross sectional shape preferably can be semicircle, it is of course also possible to be other shapes, such as it is taper, rectangular.
In the utility model, a tension spring 40 is also set up between two above-mentioned brake-shoes, the tension spring 40 is for preventing web
21 are detached from pivot pin 30, specifically, tension spring 40 is arranged between two brake-shoe webs 21, i.e. the both ends of tension spring 40 mount two respectively
The web 21 of brake-shoe.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations;Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that, it still can be to preceding
