Abstract

The invention discloses a vehicle retarder braking plier of a novel structure. The vehicle retarder braking plier comprises a braking plier body. An extending arm is arranged at the front of the braking plier body, a braking track is fixed to the extending arm, an extended edge is arranged on the part, close to the lower part, of the front side of the extending arm, and the edge extends to a position below a track head of the braking track. By applying the vehicle retarder braking plier of the novel structure, the strength of the fatigue fracture position of the braking plier is greatly improved, the service life of the braking plier is guaranteed, and a retarder is guaranteed to meet the use requirement of large axle load vehicles.

Description

The car retarder brake clamp of new structure
Technical field
The present invention relates to a kind of rolling stock retarder, particularly relate to a kind of car retarder brake clamp of new structure.
Background technology
Car retarder is vehicle ground speed control device, is arranged in hump marshalling station wire harness or station track, coordinates with control system, carries out speeds control to the vehicle in rolling.
As shown in Fig. 1 a, Fig. 1 b, Fig. 1 c, brake clamp is the key components and parts of car retarder and main stressed member, since Heavy-Haul Railway development, the accidental crackle of the brake clamp even phenomenon of rupture of retarder, mainly concentrates on the stepped portions that retarder brake clamp installs braking rail.And the shape at this position is relatively determined, reason is as follows: 1. retarder braking rail adopts the 60kg/m rail of standard or 75kg/m rail to process usually, material hardness, the resistance to abrasion of standard rail are good, and material conformability is high, meet the high strength requirement of braking rail.But Standard Guage profile is unified, and its installation site shape is determined relatively.2. the requirement of gauge in car retarder professional standard, is limited in the profile design of brake clamp within very little scope.Based on above reason, its shape of brake clamp installation braking rail position all compares in all directions to be determined, has been difficult to comparatively quantum jump.Occurring that axle heavily strengthens, when Strength Safety surplus deficiency, the measure that can take is limited.
Summary of the invention
The object of this invention is to provide that a kind of fatigue crack-resistant is strong, the car retarder brake clamp of the new structure of long service life.
The object of the invention is to be achieved through the following technical solutions:
The car retarder brake clamp of new structure of the present invention, comprise brake clamp body, the front portion of described brake clamp body is provided with extension arm, described extension arm is fixed with braking rail, the position on the lower, front of described extension arm is provided with the edge stretched out, and described edge reaches the below of the rail head of described braking rail.
As seen from the above technical solution provided by the invention, the car retarder brake clamp of the new structure that the embodiment of the present invention provides, because position on the lower, the front at extension arm is provided with the edge stretched out, described edge reaches the below of the rail head of described braking rail, when not changing existing car retarder professional standard gauge and standard braking rail, substantially improve the intensity of brake clamp at fracture by fatigue position, ensure that the life-span of brake clamp, ensure that retarder adapts to the operating needs of heavy axle load car.

In figure: 1, extension arm, 2, edge, 3, braking rail.
Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
The car retarder brake clamp of new structure of the present invention, its preferably detailed description of the invention as shown in Fig. 2 a, Fig. 2 b, Fig. 2 c:
Comprise brake clamp body, the front portion of described brake clamp body is provided with extension arm, and described extension arm is fixed with braking rail, and the position on the lower, front of described extension arm is provided with the edge stretched out, and described edge reaches the below of the rail head of described braking rail.
Described brake clamp body and extension arm and edge are integral type structure.
The length at described edge and the length of described extension arm identical or different.
Described braking rail adopts railway standard 60kg/m rail or 75kg/m rail.
As shown in Figure 1 d, in prior art, brake clamp only body reaches below braking rail, and extension arm does not reach below braking rail.
As shown in Figure 2 d, the car retarder brake clamp of new structure of the present invention, still adopt railway standard 60kg/m rail or 75kg/m rail, but local structure adopt the edge stretched out, reach below braking rail rail head, this structure substantially improves the intensity of brake clamp at fracture by fatigue position, ensure that the life-span of brake clamp.Ensure that retarder adapts to the operating needs of heavy axle load car.
The structure commonality of this kind of band edge is good, all can apply in each model retarder brake clamp, portable good.
Whether the length at edge is not limited to same long with brake clamp extension arm.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
