Brake caliper device for train

Abstract

The invention relates to a train braking clamp device. The train braking clamp device comprises a rack, installing plates, sliding rails, braking air cylinders and brake pads. The rack comprises a left clamping plate and a right clamping plate. The upper portion and the lower portion of the left clamping plate and the upper portion and the lower portion of the right clamping plate are provided with the sliding rails correspondingly. The installing plates are arranged on the inner side of the left clamping plate and the inner side of the right clamping plate correspondingly and can be fixed tothe sliding rails in a sliding manner. The brake pads are symmetrically arranged on the opposite sides of the two installing plates. The braking air cylinders are circumferentially arranged on the outer side of the left clamping plate and the outer side of the right clamping plate. The two layers of braking air cylinders are arranged on the outer side of the left clamping plate and the outer sideof the right clamping plate, and the number of the inner-layer braking air cylinders is larger than the number of the outer-layer braking air cylinders. By means of the braking clamp device, a brake disc can be evenly abraded and emit heat in the braking process, and the service life is prolonged; and the structure is simple, the maximum weight is only 56 kg, the weight is obviously reduced, and the weight reduction ratio reaches 34%.

Description

technical field [0001] The invention belongs to the field of brake caliper devices, in particular to a brake caliper device for trains. Background technique [0002] Train braking can be divided into common braking and emergency braking according to the purpose. At present, the common braking methods of trains can be divided into two types, one is brake shoe braking, and the other is disc braking. The brake disc is usually divided into two ways of being installed on the axle and on the side of the wheel web. The existing brake caliper moves through the telescopic action of the brake cylinder, so that the brake lever is supported by the shafts on both sides of the lever hanger to rotate. , so that the brake pads can clamp the brake disc or loosen the brake disc to realize the process of braking and loosening the brake. However, due to the different circumferences of the inner and outer rings of the brake disc, the brake disc wears and heats unevenly, and the existing brake cl...

AI Technical Summary

Problems solved by technology

The present invention relieves oil flow, releases oil and brakes, and is safer. There is a manual gap adjustment mechanism in the oil cylinder, which has a simple structure, is not prone to failure, and is also quite simple to maintain. The parts of the caliper mechanism are simple geometric bodies, which are easy to assemble. High strength, no deflection with the brake disc, the same invention can not solve the problem of brake disc wear and uneven heating
