Automotive disk brake with good sealing performance

Abstract

The invention discloses an automotive disk brake with a good sealing performance. The automotive disk brake comprises a brake seat, a brake fluid guide tube is movably mounted at the upper end of thebrake seat, a pneumatic box is movably mounted at the upper end of the brake fluid guide pipe, a pneumatic piston is arranged in the brake fluid guide pipe, and a sealing pad for enhancing the sealingperformance is arranged between the pneumatic box and the pneumatic piston. A brake fluid flow guide tube is mounted at the upper end of the pneumatic box, a brake hydraulic cylinder is mounted at the upper end of the brake fluid flow guide tube, a pneumatic tube is movably mounted on one side of the pneumatic box, a cylinder is movably mounted on one side, far away from the pneumatic box, of thepneumatic tube, a pushing rod is fixedly mounted in the middle of one side, far away from the pneumatic tube, of the cylinder, and a brake pedal is fixedly mounted on one side, far away from the cylinder, of the pushing rod. In the use process, the automotive disk brake is more stable in brake, brake pressure is uniformly distributed, a brake arm can timely return after brake, a steel disc rubs with a brake pad to make a sound when the brake pad wears out, a driver is reminded to replace the brake pad, and the use process is optimized.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a disc brake for automobiles with better sealing performance. Background technique [0002] With the development of society, small cars have spread to every household. As people's first choice of transportation, the safety of cars has always been concerned. Unavoidable accidents will occur during the driving of cars. In order to reduce the occurrence of traffic accidents, it is necessary to A moving car performs emergency braking, but the existing disc brakes are simple in structure, and most of them are suspension disc brakes. After a long time of use, the brake arm will be stuck and difficult to return, causing serious damage to the brake disc. Wear and tear, brake pressure distribution is uneven, and the driver cannot be reminded in advance when the brake pads are about to wear out, which is prone to brake failure, which has certain dangers and reduces the performance of the de...

[0002] With the development of society, small cars have spread to every household. As people's first choice of transportation, the safety of cars has always been concerned. Unavoidable accidents will occur during the driving of cars. In order to reduce the occurrence of traffic accidents, it is necessary to A moving car performs emergency braking, but the existing disc brakes are simple in structure, and most of them are suspension disc brakes. After a long time of use, the brake arm will be stuck and difficult to return, causing serious damage to the brake disc. Abrasion, uneven brake pressure distribution, unable to remind the driver in advance when the brake pads are about to wear out, prone to brake failure, there is a certain risk, and the performance of the device will be reduced
