Abstract

The invention belongs to the technical field of unit brake cylinders, in particular to a unit brake cylinder with automatic parking function. The technical solution is: a unit brake cylinder with automatic parking function, including a cylinder body, a limit mechanism is fixed in the middle of the cylinder body, a brake piston and a parking piston are respectively arranged in the cylinder body, and the brake piston and the parking piston are respectively located in the On both sides of the limit mechanism, the brake piston is connected with an adjustment mechanism, and the adjustment mechanism is connected with a push rod; the parking piston is connected with a parking piston rod, and the other end of the parking piston rod is fixed with a spring retaining ring, and the spring retaining ring A parking spring is connected with the cylinder body, and a manual relief mechanism is connected to the spring retaining ring. A parking step for pushing the adjustment mechanism to move is provided on the side of the manual relief mechanism away from the parking piston. The invention provides a unit brake cylinder with automatic parking function.

Description

technical field [0001] The invention belongs to the technical field of unit brake cylinders, and in particular relates to a unit brake cylinder with an automatic parking function. Background technique [0002] Due to structural limitations, engineering vehicles often use a highly integrated unit cylinder structure. The unit cylinder generally has functions such as braking, automatic compensation of brake shoe clearance, and automatic parking. At present, the most commonly used parking technology of engineering vehicle unit cylinder is hand brake and spring parking technology. Compared with ordinary hand brake, the spring parking technology can greatly reduce the labor intensity of the operator, and there will be no forgetting to release the parking brake. Therefore, more and more construction vehicles adopt the more intelligent spring parking technology. However, when the hand brake is used for parking braking, a separate operation is required, and automatic parking braking...
