Problems solved by technology

In this way, in some special heavy-duty transportation conditions where the size of the axle is limited, and the braking force is required to be large enough, the axle that does not have the dust-proof function and uses the brake chamber for braking cannot meet the use requirements.

Abstract

The invention relates to a hydraulic brake oil cylinder assembly for a heavy-loaded vehicle bridge. The hydraulic brake oil cylinder assembly is arranged in the middle of the heavy-loaded vehicle bridge; the hydraulic brake oil cylinder assembly is connected with two cam swing arms on the inner side of the vehicle bridge through a brake fork connection assembly, and the cam swing arms are directly connected with a drum brake inside a rim; an installing fork is arranged at the top of the hydraulic brake oil cylinder assembly; the installing fork is fixedly connected with the brake fork connection assembly through a pin; a pushing rod is arranged on the upper side inside the hydraulic brake oil cylinder assembly; the pushing rod is connected with the installing folk through threads in a fastened mode. The hydraulic brake oil cylinder assembly for the heavy-loaded vehicle bridge has the advantages that the structure of the hydraulic brake oil cylinder assembly can be changed so as to be applied to the heavy-loaded vehicle bridge With the braking force required to be large enough and the size limited; meanwhile, compared with the vehicle bridge using a brake chamber, the hydraulic brake oil cylinder assembly has the advantages of being good in dustproof effect, convenient to install and the like.

Description

technical field [0001] The invention relates to a hydraulic brake oil cylinder assembly for a heavy-duty vehicle axle. Background technique [0002] The maximum working pressure of the hydraulic cylinder is set by the relief valve, the working pressure of the hydraulic cylinder is set by the pressure reducing valve, and the cylinder head can be used to clamp the workpiece. When the piston of the hydraulic cylinder goes down, a certain stable value lower than the set pressure of the relief valve is obtained through the pressure reducing valve, and the oil in the upper cavity of the hydraulic cylinder can be returned to the oil tank through the one-way valve during the return stroke. The maximum working pressure of the hydraulic cylinder is set by the relief valve. The outlet pressure of the pressure reducing valve is set by the valve itself. When the remote control port of the valve is connected to the valve port, the outlet pressure of the valve is set by the valve body. T...
