Abstract

The invention belongs to the technical field of unit brake cylinders, and particularly relates to a unit brake cylinder with an automatic parking function. According to the technical scheme, the unit brake cylinder with the automatic parking function comprises a cylinder body, wherein a limiting mechanism is fixed to the middle of the cylinder body, a brake piston and a parking piston are arranged in the cylinder body and arranged on the two sides of the limiting mechanism respectively, an adjusting mechanism is connected into the brake piston, and a push rod is connected into the adjusting mechanism; a parking piston rod is connected to the parking piston, a spring check ring is fixed to the other end of the parking piston rod, a parking spring is connected between the spring check ring and the cylinder body, a manual relieving mechanism is connected to the spring check ring, and a parking step used for pushing the adjusting mechanism to move is arranged on the side, away from the parking piston, of the manual relieving mechanism. The invention provides a unit brake cylinder with an automatic parking function.

Description

technical field [0001] The invention belongs to the technical field of unit brake cylinders, in particular to a unit brake cylinder with automatic parking function. Background technique [0002] Due to structural limitations, engineering vehicles often adopt a highly integrated unit cylinder structure. Unit cylinders generally have functions such as braking, automatic compensation of brake shoe clearance, and automatic parking. At present, the most commonly used parking technology for the unit cylinder of engineering vehicles is the hand brake and spring parking technology. Compared with ordinary hand brakes, the spring parking technology can greatly reduce the labor intensity of the operator, and there will be no chance of forgetting to release the parking brake and running with the brake Therefore, more and more construction vehicles adopt spring parking technology with higher intelligence. But, when adopting handbrake to carry out parking brake, need to operate separatel...
