Embodiment Construction

[0017] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, a rail car braking device shown in the first embodiment of the present invention is installed on the wheel frame of the rail car wheel set, and the rail car braking device includes a brake frame 13 installed on the wheel frame, so that the brake The device maintains a relatively stable relative position with the track rail 11. The brake frame 13 includes a rail sleeve 15 with a T-shaped groove inside and can half-embrace the steel rail 11, so that the cross-sectional shape of the brake frame 13 is an ancient Chinese character with a half opening in the middle of the bottom. The rail sleeve 15 is set on the periphery of the rail 11, and the top, left side, right side, left bottom, right bottom and the rail 11 inside the rail sleeve 15 are all provided with brakes 16 fixedly connected to the rail sle...

Abstract

The invention discloses a braking device for a railcar. The braking device is arranged on a wheel carrier of a wheel set of the railcar. The braking device for the railcar comprises a braking frame arranged on the wheel carrier, wherein the braking frame comprises a rail sleeve capable of half-encircling a steel rail; a T-shaped groove is formed in the rail sleeve; brakes fixedly connected to the rail sleeve are arranged between the inner top, the left side part, the right side part, the left bottom and the right bottom of the rail sleeve and the steel rail. The steel rail is half-encircled by the T-shaped groove of the rail sleeve, the T-shaped groove turns to the bottom side of the steel rail, the brakes are arranged on the inner side of the rail sleeve, and are positioned between the rail sleeve and the steel rail, and gaps are formed between the brakes and the steel rail when the railcar normally runs, and are pneumatically expanded to drive the brakes to be closely attached to the steel rail to encircle the steel rail from the top, the left side part, the right side part, the left bottom and the right bottom in case of emergency braking, so that the railcar is synchronously braked under equal pressure in five gears and five points in emergency, derailment and tailgating are avoided, damage to the steel rail at low gears is avoided, safety is ensured by sacrificing the steel rail at high gears, and higher reliability of braking within a visual distance is achieved.

Description

technical field [0001] The invention relates to braking technology, in particular to a rail vehicle braking device. Background technique [0002] At present, rail transit (such as high-speed railway, light rail and subway, etc.) has gradually become an important means of transportation in and between cities, carrying a large number of citizens' daily travel, and rail transit safety has naturally become the most important issue. Existing rail vehicle braking device all is to use wheel braking. The most common braking method used by rail locomotives is brake shoe braking. The tile-shaped brake blocks made of cast iron or other materials hold the wheel tread tightly during braking and stop the wheel through friction; The new braking method adopts disc brake, which is to install the brake disc on the axle or on the side of the wheel spoke plate, and use the brake caliper to make the two brake pads made of synthetic materials press the side of the brake disc tightly. Braking fo...
