The invention belongs to the technical field of brake maintenance tools, and particularly relates to a pneumatic brake cylinder resetting tool which comprises a sleeve and a screw rod. The outer wallof the sleeve is provided with two clamping grooves with flat end faces. The screw rod penetrates through the axial direction of the sleeve and is in threaded connection with the sleeve, a handle containing cavity for containing a handle is arranged in the screw rod, and a handle connecting head is fixed at one end of the screw rod. The hollow screw rod is arranged, the handle is accommodated in the hollow screw rod, the handle can be pulled out when in use, the force borne during rotation is carried through the handle connecting head, and the storage space can be greatly reduced when the hollow screw rod is stored. A base plate capable of being directly clamped through the clamping grooves, therefore, the base plate can be directly and conveniently installed, the base plate is provided with anti-skid lines which are in fit with a bearing face to increase friction force, and operation reliability is ensured. Therefore, when a user uses the tool, the user can rapidly, conveniently and reliably use the tool for resetting a cylinder piston.
Description
technical field [0001] The invention belongs to the technical field of brake maintenance tools, and in particular relates to a pneumatic brake cylinder reset tool. Background technique [0002] The brake cylinder is an indispensable chassis brake part of the brake system. Its main function is to push the brake pads, and the brake pads rub against the brake drum. Slow down and stop the vehicle. After the brake is stepped on, the master cylinder generates thrust to press the hydraulic oil to the sub-cylinder, and the piston inside the sub-cylinder starts to move under the hydraulic pressure to push the brake pads. The hydraulic brake is composed of the brake master cylinder and the brake oil storage tank. They are connected to the brake pedal at one end and the brake hose at the other end. Brake fluid is stored in the brake master cylinder, and has an oil outlet and an oil inlet. [0003] The existing brake sub-cylinder tools are large in size, which is not conducive to sto...
