A vehicle noise reduction brake beam with remarkable noise reduction effect

Abstract

The invention discloses a vehicle noise reduction brake beam with remarkable noise reduction effect, specifically relates to the technical field of vehicle noise reduction, including a chassis, the front of the chassis is provided with a brake pump, and two outlets of the brake pump The openings are respectively connected with the opposite ends of the two brake fluid guiding beams, and the backs of the two brake fluid guiding beams are fixedly connected with the front of the chassis. By setting the chute, the brake drum and the chamfer, since both ends of the two brake shoes and the sound-absorbing sheet on the surface of the brake shoe are provided with chamfers, and the chamfers at both ends are piled up with each other, when using the brake drum , the structure inside the brake drum can effectively change the natural sound frequency. During the braking process, the friction powder that appears when the brake shoe is worn can be discharged from the chute for cleaning, thereby reducing the accumulation of residues in the brake drum. As a result, the brake drum is damaged due to excessive accumulation of dust, thereby reducing the noise of the brake beam and ensuring the service life of the brake beam.

Description

technical field [0001] The invention relates to the technical field of vehicle noise reduction, and more specifically, the invention relates to a vehicle noise reduction brake beam with remarkable noise reduction effect. Background technique [0002] Common car noise mainly includes tire noise, road noise, wind noise, engine noise, brake noise, etc. Brake noise is a common noise when a car is braking. [0003] Chinese patent document (CN108860122A) discloses a new type of brake system vibration and noise reduction modular bracket. It is also one of the latest research work of the engineers of major OEMs to reduce various noise sources and reduce the noise level. As we all know, even the passenger cars with air brakes produced by domestic mainstream bus manufacturers, if the whole vehicle uses piston reciprocating air The compressor, due to the movement characteristics of the piston, will cause the noise of the dryer or condenser at the end of the air pumping circuit. The s...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vehicle noise-reducing brake beam with remarkable noise-reducing effects. The hydraulic cylinder discharges the liquid into the brake disc, so that the liquid pushes the brake friction wheel inside the brake disc to contact the brake wheel connected in the wheel, thereby increasing the friction force when the brake wheel rotates. At this time, the brake The wheel will be locked due to the friction between the friction wheel and the friction wheel, but the hard friction method will not only greatly shorten the service life of the friction wheel and the brake wheel, but also easily affect the rest of the car due to the high temperature generated during friction. At the same time, because the friction wheel will make a loud noise due to friction during braking, it will not only cause a certain amount of noise pollution to the environment, but also frighten and affect the surrounding pedestrians.
