Ural car

Ural vehicles have three independent brakes: a service brake with a hydropneumatic drive on all wheels, a parking brake with a mechanical drive acting on the transmission, and an auxiliary compression type installed on the pipelines of the gas exhaust system

Compressor (Fig. 1) piston type, indirect flow, two-cylinder, single-stage compression

Air from the engine air filter enters the compressor cylinders through the vane inlet valves.

The pressure regulator is designed to regulate the pressure of compressed air supplied from the compressor

The two-section brake valve (Fig. 1) is designed to control the actuators of the vehicle’s service brake system, as well as to control the trailer brake drive valve

Service brakes are disassembled during maintenance and troubleshooting (oiling, wear and tear of brake pad linings, wear or damage to the sealing collars of wheel cylinders, breakage of the tension spring, etc.)

Drum-type parking brake with mechanical drive (Fig. 1)

The parking brake drive is connected by lever and rod to lever 13 of the brake valve, which ensures that when the vehicle is braked with the parking brake, the service brake system of the trailer (semi-trailer) is activated.
