Problems solved by technology
In the past structure of the brake cylinder, the cylinder block is mostly designed with an oil inlet directly on the top. This structure has no dust-proof device, and it is easy for dust and moisture to enter the cylinder block after long-term use, resulting in piston jamming and oil leakage. Waiting for failure

The invention discloses an automatic adjusting structure of a hub gap of a rear brake slave cylinder, comprising a cylinder body, wherein the cylinder body is internally provided with an oil cavity which is internally provided with a left piston and a right piston; the rear end of the left piston is provided with an installing hole with internal threads; the internal threads of the installing hole are connected with an adjusting screw; the rear end of the adjusting screw is fixedly provided with an adjusting ratchet wheel; a gap adjusting claw is matched outside the adjusting ratchet wheel; the rear end surface of the left piston is fixedly provided with an L-shaped connecting piece; the upper end of the connecting piece is fixedly provided with a fastener; the side wall of the cylinder body is fixedly provided with a supporting spring; and the other end of the supporting spring is hooked in the fastener. In the automatic adjusting structure, the axial displacement for the pistons is realized by the pre-tensioning force of the spring, the structure is simple, the volume is small, the installation and the use are easy and the use performance of the brake cylinder is improved.
Description
technical field [0001] The invention relates to the field of automobile rear brake pumps, in particular to an automatic adjustment structure for wheel hub clearances of rear brake cylinders. Background technique [0002] The brake cylinder is an indispensable part of the braking system. Its main function is to push the brake pads, and the brake pads rub against the brake drum to reduce the speed of the vehicle and stop it. After stepping on the brakes, the master cylinder generates thrust to push the hydraulic oil down to the brake cylinders. Under the pressure of the pistons in the pump body, the brake oil pipes are squeezed out of the oil pipes and flow to each brake cylinder for braking function. when the brake pedal is released. The oil outlet in the brake master cylinder will be closed, and the oil inlet will be opened, so that the brake oil will flow back from each brake sub-cylinder into the brake master cylinder and return to the original state. In the past struct...
