Abstract

The utility model discloses a brake lever, belonging to the technical field of railway vehicles and machineries. The brake lever comprises a lever main body, an upper pin hole, a lower pin hole and a middle pin hole; wherein a flexible liner is arranged in each of the upper pin hole, the lower pin hole and the middle pin hole. The brake lever is simple in manufacturing and convenient to exchange; the brake lever can be installed according to different requests, therefore, the assembling efficiency in the production is enhanced; the uneven brake caused by bias of the brake beam is reduced in the brake process, and the consumption of the brake power is avoided; the maintaining time is prolonged, and the repairing cost is reduced. Therefore, the brake lever is widely used in the brake system of each railway vehicle.

Description

Brake lever

Affiliated technical field

The utility model relates to a kind of guideway vehicle parts, especially brake component, belongs to guideway vehicle and field of mechanical technique.

Background technology

At present, guideway vehicle safely and steadily runs, and its stable performance, safe and reliable brake system are absolutely necessary.Along with the heavily stressed development of railway high speed, the consumption of the wearing and tearing of brake system, the eccentric wear of brake beam, braking force also becomes increasingly conspicuous.In the brake system of deflection angle was arranged, the deflection and the eccentric wear of brake beam were more serious.

The utility model content

To above-mentioned deficiency, the utility model provides a kind of can reduce brake system worn-down brake lever.

The utility model solves the technical scheme that its technical matters adopted: brake lever, and comprise lever main body, go up pin-and-hole, following pin-and-hole and middle pin-and-hole, be provided with flexible liner in last pin-and-hole, following pin-and-hole, the middle pin-and-hole.

The beneficial effect of the utility model is that manufacturing is simple, changes conveniently, can install according to different needs, improves the packaging efficiency of production; It is uneven in braking procedure, to reduce the braking that the lateral deviation of brake beam causes, avoids the consumption of braking force; Prolong maintenance time, reduce maintenance cost.Can be widely used in the brake system of various guideway vehicles.

Parts and numbering among the figure:

The 1-lever main body, the last pin-and-hole of 2-, pin-and-hole under the 3-, pin-and-hole among the 4-,

The 5-lining, the outer ball cover of 5-1-, ball cover in the 5-2-, 5-3-lining outer ring, 5-4-lining inner ring, 5-5-rubber bodies.

The specific embodiment

Below in conjunction with embodiment the utility model is further specified.

Embodiment one:

Referring to Fig. 1,2, brake lever comprises lever main body 1, goes up pin-and-hole 2, pin-and-hole 3 and middle pin-and-hole 4 down, last pin-and-hole 2, descends in pin-and-hole 3, the middle pin-and-hole 4 to be provided with flexible liner 5.

Lining 5 is made up of outer ball cover 5-1 that cooperatively interacts and interior ball cover 5-2.Interior ball cover 5-2 ball cover 5-1 outside is interior with small angle deflection.Abrasion between lining and the brake lever are reduced.

Embodiment two:

Referring to Fig. 1,3, brake lever comprises lever main body 1, goes up pin-and-hole 2, pin-and-hole 3 and middle pin-and-hole 4 down, last pin-and-hole 2, descends in pin-and-hole 3, the middle pin-and-hole 4 to be provided with flexible liner 5.

Lining 5 is made up of lining outer ring 5-3, lining inner ring 5-4 and the rubber bodies 5-5 that is clipped between the two.Rubber bodies 5-5 can be with small angle deflection.Abrasion between lining and the brake lever are reduced.

Last pin-and-hole 2, whether pin-and-hole 3, middle pin-and-hole 4 can select mounting bush according to concrete needs down.
