Pump-adjuster of braker with pressure-releasing valve

Abstract

A brake subpump adjuster with a pressure-relief valve comprises a cylinder, a lever, a push rod, an intake valve and a pressure-relief valve. The cylinder has first and second ends and at the first end is disposed a fixed piece. One end of the lever is set at the second end of the cylinder and the other end has a joint. The push-rod movable passes through the cylinder and the handle. At one end of the push-rod is disposed a support piece to press the subpump and at the other end is disposed a handle to rotate the push-rod. The intake valve is disposed on one side of the lever to make the piston move, so as to make the push-rod shift. The pressure-relief valve is set on the other side of the lever for relasing high-pressure gas from the cylinder to pull back the push-rod to the initial position.

Description

technical field [0001] The invention mainly discloses a brake cylinder regulator, in particular, a brake cylinder regulator with a pressure release valve. Background technique [0002] At present, the brake cylinder of automobiles will gradually protrude as the brake pads wear and become thinner. When the brake pads are worn to a certain extent and must be replaced, the cylinder shaft must be rotated and pressurized to return to the original distance. Replace with new brake pads. [0003] However, the structure of the traditional sub-pump adjuster (as shown in Figure 1 and Figure 2) approximately includes a screw rod 1, 1a, one end of which is provided with a handle 5, the other end is provided with a resisting piece 4, a fixing piece 2, and a There is a nut 3 on the side to allow the screw 1 to pass through, so as to achieve the effect of pressing the sub-pump 6 in. However, the general disc brake sub-cylinder is shared with the hand brake, and some sub-cylinders use righ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the brake cylinder regulator with a pressure relief valve in the present invention is that the rotation of the screw of the known cylinder regulator must consider the rotation direction of the screw teeth of the cylinder for corresponding use, so maintenance personnel need to At the same time, two kinds of screw rotation directions are prepared for use together, which is more inconvenient for maintenance.
