Abstract
The utility model provides a middle-rear axle brake shoe assembly for a mine car, which effectively avoids the dropping of a roller matched with a cam shaft. The middle-rear axle brake shoe assembly comprises an arc brake shoe for fixing and supporting, a brake lining sheet fixed at the outer surface of the brake shoe and a roller arranged at one end of the brake shoe, wherein the roller is rotationally fixed on the brake shoe by a roller shaft passing through the roller. The middle-rear axle brake shoe assembly is provided with the roller shaft matched with the roller, so the dropping of the roller is effectively avoided; the middle-rear axle brake shoe assembly further has larger brake moment for the worse mine environment; the brake lining sheet of the utility model can be made as the shape that two ends are thin, and the middle part is thick, thereby effectively using the frication materials on the brake lining sheet.
Description
Technical field
The utility model relates to back axle brake shoe assembly in a kind of mining car, in particular, relates in particular to back axle brake shoe assembly in the mining car that a kind of roller that can effectively avoid matching with camshaft comes off.
Background technique
The present about 410～420mm of the normally used brake shoe assembly diameter of the mining bridge of heavy truck, the about 180～220mm of brake shoe width, brake shoe assembly adopts this size, and braking effect is not good under the industrial and mineral environment; Roller remains on the brake shoe by return spring and camshaft, in use easily comes off; During using, brake lining has the drawback that wearing and tearing are inhomogeneous and friction material can not effectively be used.
Summary of the invention
The utility model is in order to overcome the shortcoming of above-mentioned technical problem, and back axle brake shoe assembly in the mining car that a kind of roller that can effectively avoid matching with camshaft comes off is provided.
Back axle brake shoe assembly in the mining car of the present utility model, comprised the arc brake shoe of fixing and supporting effect, the roller that is fixed on the brake lining of brake shoe outer surface and is arranged on brake shoe one end, its specialization is: described roller is rotatably fixed on the brake shoe by the roller shaft through himself.In the process of using, roller is used for matching with the camshaft of brake assembly, so that realize the corresponding sports of brake shoe; But because existing roller is embedded on the brake shoe, along with the prolonged exercise of roller on brake shoe, roller is more or less freely to come off from brake shoe, after roller is fixedly installed on the brake shoe by roller shaft rotationally, has just avoided coming off of roller effectively.
Back axle brake shoe assembly in the mining car of the present utility model, described brake lining are circular arc, and circular arc brake lining place diameter of a circle is 490～510mm; The width of brake shoe and braking plate is 230～240mm.The width of the length of brake lining and width and brake shoe has all carried out increasing to a certain degree, and helping increases the moment that break produced that adopts brake shoe of the present utility model, makes mining car have good braking ability.
Back axle brake shoe assembly in the mining car of the present utility model, the thickness of described brake lining neutral position is greater than the thickness at brake lining two ends.Brake lining employing two ends are thin, the structure of thick middle, help making full use of the friction material on the brake lining.
Back axle brake shoe assembly in the mining car of the present utility model, the other end of described brake shoe offer and are used for the fixed pin holes of brake shoe rotational fixation on the braking chassis.In the process of using, by cooperating of fixed pin holes and fixing pin, can be fixedly installed on brake shoe rotationally on the braking bottom board, realized the brake shoe mechanism stability effectively.
Back axle brake shoe assembly in the mining car of the present utility model offers the return spring fixed hole on the described brake shoe.In use, two brake shoes are oppositely arranged, and the return spring fixed hole on the two ends of return spring and two brake shoes fixes, so that realize the return of brake shoe.
The beneficial effects of the utility model are: the utility model has not only been realized being rotationally connected of roller and brake shoe by the roller shaft that matches with roller is set, and has also realized roller is securely fixed on the brake shoe, has avoided coming off of roller effectively; Size of the present utility model is bigger than the size of existing brake shoe, makes it have bigger braking moment, adapts to comparatively abominable industrial and mineral environment more; Brake lining in the utility model can make that two ends are thin, the shape of thick middle, has effectively utilized the friction material on the brake lining.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model;
Fig. 2 is the structural representation of looking up of the present utility model.
Among the figure: 1 brake lining, 2 brake shoes, 3 roller shafts, 4 rollers, 5 return spring fixed holes, 6 fixed pin holes.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As depicted in figs. 1 and 2, provided the structural representation of plan view of the present utility model and worm's eye view respectively, it comprises brake lining 1, brake shoe 2, roller shaft 3, roller 4, brake shoe 2 plays fixing and carrying effect, brake lining 1 is fixed on the brake shoe 2 by rivet, the outer surface of brake lining 1 is a friction material, so that realize better braking ability.One end of brake shoe 2 offers the fixed hole that matches with roller shaft 3, and roller shaft 3 merges through roller 4 by matching with this fixed hole, has realized being rotationally connected of roller 4 and brake shoe 2; The other end of brake shoe 2 has and fixed pin holes 6, and this fixed pin holes 6 cooperates with the respective fixation pin, can realize being rotationally connected of brake shoe 2 and braking bottom board, has guaranteed the stability of brake shoe 2 effectively.Also be provided with the return spring fixed hole 5 that matches with return spring on the brake shoe 2, so that realize fixation to return spring.
Brake lining 1 two ends are thin, thick middle, so that make full use of the friction material on the brake lining 1 and guarantee that brake lining has good braking ability.Circular arc brake lining place diameter of a circle is 490～510mm; The width of brake shoe and brake lining is 230～240mm, adopts this structure to help increasing the moment that break produced that adopts brake shoe of the present utility model, makes mining car have good braking ability.
