Abstract
The invention belongs to the field of automotive part processing and particularly relates to a sound insulation device of an automotive damper. The sound insulation device comprises a sound insulation cover and a sound insulation cover fixation platform, wherein the sound insulation cover is arranged on the sound insulation cover fixation platform which is arranged on a shell of the automotive damper. The sound insulation device of the automotive damper is capable of effectively insulating noises produced by the damper and improving the integral qualities of a vehicle and driving safety and reliability.
Description
Technical field
The invention belongs to auto-parts technical field, relate in particular to a kind of sound arrester of automobile absorber.
Background technique
Concussion when vehicle shock absorber is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, therefore the harder vibration damper of the general employing of heavier car.
Generally, vibration damper is arranged between vehicle body and wheel, and wherein the upper end of piston rod is fixed to vehicle body, and urceolus or outer tube are fixed to wheel side.For this reason, the upper end of piston rod is provided with the upper mounting structure that can be fixed to vehicle body, and simplified lower end is provided with the knuckle support that is connected to wheel shaft.
Vehicle shock absorber is an important mechanism that connects automobile suspension system and automobile chassis, common vibration damper is provided with the compression system of spring or hydraulic pressure or its combination, the impact force of utilizing the stretchability of vibration damper compression system can absorb suspension system to pass to automobile chassis, effect is the vibration that buffering vehicle produces in the time of rugged road traveling.Vehicle shock absorber can produce certain noise in perseveration process, due to vibration damper and generally reserved matching hole position, vehicle body joint, aperture is larger, vibration damper impacts like this noise and air-flow acoustic capacitance are easily delivered in compartment by this hole, the travelling comfort of taking is exerted an influence, noise not only can disperse driver's attention, also can make driver produce sense of fatigue.
For solving this technical problem, some high-quality vehicles adopt the mode of filling binding site to carry out isolation damper noise, general packing is frothing foam or polyurethane foam, but need to consider packing and coordinating of component around, its construction cycle is long, cost is high, and need checking to increase the negative effect that these component bring.Prior art, under the restriction of the links such as design research and development, manufacturing process, cost of production, for reducing costs, is not carried out technical finesse to common vehicle with regard to this problem.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of sound arrester of automobile absorber.The sound arrester of this vibration damper can effectively be isolated the noise that vibration damper part produces, and the quality of lifting vehicle entirety has increased the safety and reliability of driving.
A sound arrester for automobile absorber, the sound arrester of described automobile absorber comprises sound-insulating cover, sound-insulating cover fixed platform, described sound-insulating cover is arranged in described sound-insulating cover fixed platform, in described sound-insulating cover fixed platform, is arranged on the shell of automobile absorber.
Preferably, described sound-insulating cover comprises outer sound-insulating cover and internal sound insulation cover.
Preferably, sound insulation by filling material in the spatial transition in described outer sound-insulating cover and described internal sound insulation cover besieged city.
Preferably, the lower edge of described outer sound-insulating cover and internal sound insulation cover is provided with lobe, and the corresponding position of described sound-insulating cover fixed platform is provided with groove, and the described lobe of described outer sound-insulating cover and internal sound insulation cover engages with described groove or be bonding.
Preferably, in described sound-insulating cover fixed platform, be provided with flange, described sound-insulating cover fixed platform can engage with car body by described flange.
