Vehicle noise reduction brake beam with remarkable noise reduction effect

Abstract

The invention discloses a vehicle noise reduction brake beam with a remarkable noise reduction effect, and particularly relates to the technical field of vehicle noise reduction. The vehicle noise reduction brake beam comprises a chassis, a brake pump is arranged on the front surface of the chassis, and two liquid outlets of the brake pump are respectively communicated with one ends of opposite surfaces of two brake liquid guide beams; and the back surfaces of the two brake liquid guide beams are fixedly connected with the front surface of the chassis. By arranging an inclined groove, a brakedrum and chamfers, the chamfers are arranged at two brake shoes and the two ends of silencing pieces on the surfaces of the brake shoes, and the chamfers at the two ends are stacked, so that when thebrake drum is used, the inherent sound frequency can be effectively changed through the structure in the brake drum; and friction piece powder caused by abrasion of the brake shoes can be effectivelyremoved from the inclined groove in the braking process, so that the situations that residues are accumulated in the brake drum, and consequently the brake drum is damaged due to the excessive accumulated dust in the brake drum are reduced, noise generated by the brake beam is reduced, and meanwhile the service life of the brake beam is guaranteed.

Description

Technical field[0001]The present invention relates to the technical field of vehicle noise reduction, and more specifically, the present invention relates to a vehicle noise reduction brake beam with significant noise reduction effect.Background technique[0002]The common car noises mainly include tire noise, road noise, wind noise, engine noise, braking noise, etc. Braking noise is a common type of noise during braking.[0003]The Chinese patent document (CN108860122A) discloses a new type of brake system vibration reduction and noise reduction modular bracket. It is also one of the latest research work by the engineers of major OEMs to reduce noise sources and reduce the noise level. As we all know, even for the passenger cars with air brakes produced by mainstream domestic passenger car manufacturers, such as the whole car adopts piston reciprocating air The compressor, due to the movement characteristics of the piston, will cause the "dada" noise of the dryer or condenser at the en...

AI Technical Summary

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.
