Disc brake device for automobile braking

Abstract

The invention relates to the technical field of machine manufacturing, and discloses a disc brake device for automobile braking. The disc brake device for automobile braking comprises a brake caliperand a brake disc, a brake groove is formed in the bottom of the middle of the brake caliper, friction plates are movably installed at the two sides of the brake groove, and rotating blades are annularly, evenly and fixedly installed at the outer rings of the two ends of the brake disc; air collecting grooves are formed in the middle positions, located at the bottoms of the two sides of the brake groove, of the brake caliper, screw rods are movably installed in the air collecting grooves, air blowing holes are evenly formed in one side of the brake caliper in a vertical strip shape, and a transmission cavity is formed in the position, located at the tops of the air collecting grooves, in the brake caliper; and a rotating shaft is movably installed at the position, close to the middle of thebrake caliper, of the top of the transmission cavity, and rotating spiral blades are movably mounted in the positions, located in the middles of the air blowing holes, of the transmission cavity. According to the disc brake device, the surface of the brake disc is kept clean through cooperation of the screw rods, the air blowing holes and other structures, the brake effect is guaranteed, meanwhile, heat dissipation is facilitated, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a disc brake device for automobile braking. Background technique [0002] The current car brakes are divided into two categories, one is drum brakes, and the other is disc brakes. Drum brakes are cheaper than disc brakes, but disc brakes are more convenient to work with the ABS system. It is more safe to use, so now many cars are beginning to install disc brakes, but there are still some problems in the actual use of disc brakes: [0003] 1. The brake disc is always exposed to the external environment, so when it is driving on a rainy day or a muddy road, some small solid particles will adhere to the surface of the brake disc, so that the brake pad and the brake disc will be pressed when braking. These small particles will wear the surface of the brake disc to a large extent during braking, resulting in a decrease in the subsequent braking effect, and there are ...

Problems solved by technology

[0003] 1. The brake disc is always exposed to the external environment, so when it is driving on a rainy day or a muddy road, some small solid particles will adhere to the surface of the brake disc, so that the brake pad and the brake disc will be pressed when braking. These small particles will wear the surface of the brake disc to a large extent during braking, resulting in a decrease in the subsequent braking effect, and there are certain potential safety hazards. At the same time, when the friction plate and the brake disc brake It will wear out the friction plate, and the friction plate will be ground with a lot of powdery small particles, which cannot be removed well only by a heat sink, and may also cause blockage, which will aggravate the wear situation

[0004] 2. Frictional braking between the friction plate and the brake disc will cause loss, which will cause the distance between the friction plate and the automatic disc to increase, so that the same braking effect will be required for subsequent braking, but it will take longer The braking path, that is, after the loss of the friction plate, it cannot automatically make up for this part of the loss, so that the braking effect is reduced. For users with high braking frequency, it is necessary to maintain and replace the friction plate frequently.
