Abstract

The invention relates to railway vehicles, namely to the brake equipment of truck of the car. The system of the brake equipment on each truck contains an air control valve, an auxiliary reservoir (4), an empty/load valve (3) and brake cylinders (12). The cylinders (12) exert a force directly on cross arms (10) with the brake shoes (9). The improved mounting of pneumatic brake devices on truck at preservation of demanded dimensions is offered. It provides independent transfer of brake efforts to the executive mechanism of each truck according to conditions of its operation. Increase of efficiency of braking of vehicles, reception of stable brake characteristics and operational reliability is reached.

Claims

1. The brake equipment system of the rolling stock with the pneumatics devices on each truck comprising:

a) an air distributor, b) an auxiliary reservoir, c) a load-dependent brake valve and d) at least one brake cylinder, which provides for transmission by means of linkage of the brake effort onto the truck actuating mechanism, meanwhile said devices are connected by the air pipes, characterized in that said system contains auxiliary reservoir in such a way that one (two) reservoir (s) are located in the body of truck bolster, two two- (three-)piston or double brake cylinders, synchronously acting upon the brake shoes of the wheelsets through the cross arms and located under the respective groove in the truck bolster on each side on the holders of the side frames so that the overall dimensions limits in the loaded truck state are not surpassed, meanwhile, the air distributor and load-dependent brake valve fixed on the truck bolster, also the brake cylinders and auxiliary reservoirs located on the trucks ensure the independent transmission of brake forces via the cross arms of actuating mechanism onto the wheels brake shoes of each truck in accordance with its operation conditions.

2. The system according to claim 1, characterized in that at said cross arm located on the side of the load-dependent brake valve have the sloping platform with a to top raised edge distant from the truck bolster, on which the lever of the load-dependent brake valve is put to compensate for the change in its vertical position in connection with the change of the position of the brake shoe on the wheel due to its wear and possible deviation of the wheel diameter.

3. The system according to claim 1, characterized in that two double brake cylinders are multi-piston cylinders and the air distributor has a built-in load-dependent brake valve.
