Description

Wear-proof coupler knuckle

Technical Field

The utility model relates to a connecting device between railway vehicle especially relates to a coupler knuckle of abrasionproof decreases.

Background

The coupler knuckle is a key part for realizing the coupling and transmission of traction force and impact force between locomotives and vehicles or between vehicles, and the coupler knuckle is required to bear the action of bending moment besides the action force of random and alternating traction force, compression force, impact force and the like in the application, and particularly in shunting operation, the coupler knuckle is often subjected to very large impact force, so the use condition of the coupler knuckle is very bad, and faults such as cracks, deformation, abrasion, bad tri-state action and the like are frequently generated at each part, wherein the abrasion is the most common fault, and the abrasion is a slow process, so that the coupler knuckle is difficult to find in time, has larger potential safety hazard, can not be repaired due to serious abrasion, can be directly scrapped, and huge economic loss is caused.

Disclosure of Invention

According to the technical problem above, the utility model provides a coupler knuckle of abrasionproof decreases, it is protruding including coupler knuckle body, S face, pinhole, first extension, second extension, first arch, second, coupler knuckle body head end is equipped with the S face, coupler knuckle body tail end is equipped with the pinhole, the S face both sides of coupler knuckle body are equipped with first extension and second extension respectively, be equipped with first arch on the first extension, it is protruding to be equipped with the second on the second extension, first arch is convex structure with the second arch.

Further, the thickness of each of the first extension part and the second extension part is greater than 10 mm.

Furthermore, the number of the first bulges and the number of the second bulges are respectively N, and N is more than or equal to 1.

Furthermore, the first protrusion and the second protrusion are symmetrically arranged relative to the center line of the coupler knuckle body.

Furthermore, the first protrusions and the second protrusions are arranged in a staggered mode relative to the center line of the coupler knuckle body.

Furthermore, the height range of the first protrusions and the second protrusions protruding from the S surface is 2mm-4 mm.

The utility model has the advantages that: the utility model relates to a knuckle of abrasionproof decreases, through first extension and the second extension that sets up thickness and be greater than 10mm in knuckle body both sides, can strengthen the intensity of knuckle body in weakest S face department, set up quantity more than or equal to 1' S first arch on first extension and second extension respectively, the second is protruding, when two knuckle bodies are mutually supported, first arch on the two knuckle bodies, the second arch is contradicted respectively rather than the complex extension on, thereby it has small clearance to make to correspond between the S face of direct friction originally, under the safe firm prerequisite of assurance cooperation, effectively reduced wearing and tearing, the life of knuckle body has been prolonged, the economic loss who leads to because of knuckle wearing and tearing are serious has been reduced.

Drawings

Fig. 1 is a main structure diagram of the present invention.

As shown in the figure, the coupler knuckle body-1, the S surface-2, the pin hole-3, the first extension part-4, the second extension part-5, the first bulge-6 and the second bulge-7.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: the utility model relates to an abrasion-proof coupler knuckle, which comprises a coupler knuckle body 1, an S surface 2, a pin hole 3, a first extending part 4, a second extending part 5, a first bulge 6 and a second bulge 7, wherein the head end of the coupler knuckle body 1 is provided with the S surface 2, the tail end of the coupler knuckle body 1 is provided with the pin hole 3, two sides of the S surface 2 of the coupler knuckle body 1 are respectively provided with the first extending part 4 and the second extending part 5, the thicknesses of the first extending part 4 and the second extending part 5 are both larger than 10mm, the first bulge 6 is arranged on the first extending part 4, the second bulge 7 is arranged on the second extending part 5, the number of the first bulge 6 and the second bulge 7 is N respectively, N is larger than or equal to 1, the first bulge 6 and the second bulge 7 are symmetrically arranged or staggered relative to the central line of the coupler knuckle body 1, the height range of the first bulge 6 and the second bulge 7 on the S surface 2 is 2mm-4mm, the first protrusion 6 and the second protrusion 7 are arc-shaped structures.

The working principle is as follows: set up quantity more than or equal to 1' S first arch 6, second arch 7 on first extension 4 and second extension 5 respectively, first arch 6 is not overlapped with the protruding 7 position of second on two mutually supporting coupler knuckle bodies 1, thereby guarantee during the cooperation first arch 6 on two coupler knuckle bodies 1, second arch 7 contradicts respectively rather than the complex extension on, and first arch 6, second arch 7 is the setting of convex structure, avoid hard friction, thereby make originally to have small clearance between the S face 2 that should the direct friction, under the safe firm prerequisite of assurance cooperation, effectively reduced wearing and tearing, through set up first extension 4 and second extension 5 that thickness is greater than 10mm in coupler knuckle body 1 both sides, can strengthen the intensity of coupler knuckle body 1 in weakest S face 2 department. The utility model discloses can effectively prevent wearing and tearing, prolong the life of coupler knuckle body, reduce because of the coupler knuckle serious economic loss who scraps and lead to that wears.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
