Description

                   Passenger car brake

1 Description

1.1 The technical field to which the utility model belongs.

The utility model relates to the field of rail vehicles, in particular, to the brake equipment of passenger cars.

1.2 prior art

A brake device of a car is known, comprising a brake line connected through an air distributor to a spare reservoir and a brake cylinder, the piston of which is connected to the lever gear for controlling brake pads by its rod. (Patent RU 2464186 C1, 10.20.2012).

The disadvantage of such a braking device is that it does not allow the kinetic energy of a moving car to be converted into electricity for braking needs when braking.

1.3 Disclosure of utility model

The purpose of the utility model is to increase the efficiency of the braking device of the car and the partial conversion of the kinetic energy of the car during braking into electricity for the needs of the car.

This goal is achieved by the fact that the braking device of a passenger carriage contains a wind propeller coaxially connected with a generator generating electricity for the needs of the car, located in a niche of the ceiling part of the car, closed by two mirror-shaped covers of the U-shaped profile, which are pivotally attached to the central pillar of the niche on the one hand, and on the other, through the rods to additional pneumatic cylinders receiving power simultaneously with air supply to the brake cylinder.

1.4 Brief Description of the Drawings

In FIG. 1 presents a schematic diagram of the proposed brake device of a passenger car.

The brake device of a passenger car consists of a brake line (17) located under the car, an air distributor (14), a spare reservoir (15), a brake cylinder (13), the piston of which is connected to the lever gear (12) for controlling brake pads (16), pressed to the rolling surface of the wheelset (11), the wind drive (8), coaxially connected with the generator (10), generating electricity for the needs of the car. The wind propulsion device (8) is located in the niche (3) of the ceiling part (1) under the roof (2) of the car, which is closed by two mirror-shaped covers of the U-shaped profile (6), hinged (5) attached to the central pillar (4) of the special niche ( 3) on the one hand, and on the other, through the rods to additional pneumatic cylinders (9), receiving power simultaneously with the air supply to the brake cylinder (13). The brake device of a passenger car works as follows. During braking, air through the air distributor (14) from the spare reservoir (15) enters the brake cylinder (13) and pneumatic cylinders (9). The output of the rod of the brake cylinder (13) through the linkage (12) presses the pads (16) against the wheel surface of the wheelsets (11), and the output of the rods (7) of the additional pneumatic cylinders (9) opens the mirror-shaped covers of the U-shaped profile (6) ) within the limits of the approximation of buildings. The incoming air flow captured by one of the mirror-shaped covers of the U-shaped profile (6) drives the wind propulsion and generator (10) connected to the car’s power supply system. After braking is completed, air from the brake (13) and additional pneumatic cylinders (9) is discharged through the air distributor (14) into the atmosphere, and their springs return the rods (7) to their original position. Mirror-mounted covers of the U-shaped profile (6) of the niche (3) are closed.

Using the proposed braking device of a passenger car allows increasing the braking efficiency and at the same time turning part of the kinetic energy of the moving car into electricity for the car's needs, which will significantly reduce the energy and economic costs of operating the rolling stock.
