Abstract
The invention provides a sound insulation pad for a rear hub wrap of a car. A body is of a thin shell shape and is attached with the inner wall of the rear hub wrap. The sound insulation pad is characterized in that: the body is of a layered structure which is formed by combining an upper layer and a lower layer; the body is provided with multiple mounting sinking platforms; a through hole is formed at the bottom of each mounting sinking platform; and each through hole is correspondingly matched with a projection welding stud arranged on the rear hub wrap and is fixed on the rear hub wrap through a nut. According to the invention, as an acoustic packing part, namely a sound insulation pad for a rear hub wrap is additionally provided, the noise generated by rear wheels is reduced in the running process of the car; and meanwhile, the sound insulation pad provided by the invention has a simple structure and lowers the cost.
Description
Technical field
The present invention relates to a kind of car parts, be specifically related to a kind of car rear-wheel hub bag sound insulating pad.
Background technology
Along with developing of automobile industry, people are more and more higher to the requirement of " safety, traveling comfort, the feature of environmental protection " of car, and the standard-required to " sound insulation, vibration isolation, anticorrosion, noise control " in the car cabin also improves constantly.Regulate sound quality in the car, can be by changing design, the change body construction realizes that this just need reach this purpose by revising even scrapping the car body component die, spended time is long, increase cost height; Can also carry out sound-absorbing, sound insulation to sound pollution source, existing at present Vibration absorber of car device, front and back enclosure sound heat insulating mattress, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass etc. make vibration and noise in the car passenger cabin obtain the actv. improvement.The employing noise insulation block reduces the noise in the rear wheel cover in CN 201045030Y patent, and the present invention regulates sound quality in the car by increasing wheel hub bag sound insulating pad.
Summary of the invention
The purpose of this invention is to provide a kind of car rear-wheel hub bag sound insulating pad, it can reduce the automobile noise that trailing wheel produces in driving process, and can reduce the noise in the car.
A kind of car rear-wheel hub bag sound insulating pad of the present invention, the profile of body is the shell shape, fits with the inwall of rear-wheel hub bag, and it is characterized in that: body is a laminar texture, is combined by the upper and lower; On body, be provided with a plurality of installation heavy stands, be provided with a through hole in each bottom that heavy stand is installed, each through hole be located at the projection welding double-screw bolt corresponding matching that rear-wheel hub is wrapped, and be fixed on rear-wheel hub by nut and wrap.
Described a kind of car rear-wheel hub bag sound insulating pad, the material on its described upper strata is the EVA material, the material of described lower floor is the acoustical cotton felt.
Preferred scheme: the material on described upper strata is the thick EVA material of 3.5mm, and the material of described lower floor is the thick acoustical cotton felt of 6.5mm.
Beneficial effect of the present invention:, reduced the automobile noise that trailing wheel produces in driving process by increasing acoustics packing part-rear-wheel hub bag sound insulating pad; Improved the NVH performance of car load under the situation that does not change body structure, the present invention simultaneously is simple in structure, has reduced cost.
