Abstract
The utility model discloses a radial type control arm rubber hydraulic bush which comprises an outer aluminum piece, a bush body and a flow channel. The outer aluminum piece is of an annular structure and wraps the periphery of the bush. The bush body comprises an inner pipe, a rubber body and an outer circle from the inside to the outside in sequence. The flow channel is arranged between the inner pipe and the outer circle. According to the radial type control arm rubber hydraulic bush, the damping peak value of the hydraulic bush can reach more than 60 degrees, damping and noise-removing effect is greatly enhanced, and the noise, vibration and harshness (NVH) characteristics of a suspension system are improved.
Description
Technical field
The utility model relates to the automobile shock technical field, particularly relates to a kind of radial mode control arm rubber hydraulic bushing.
Background technique
NVH (Noise, Vibration, Harshness) noise, vibration and sound vibration roughness are global questions weighing the automobile making quality.In recent years, the NVH characteristic is increasing to the influence of automobile, it is to realize by lining that irs control arm is connected with vehicle body, existing general lining is in the imbalance excitation of control road surface or wheel, drag angle was generally below 10 ° when especially low frequency and large amplitude encouraged, can not well reach vibration damping de-noising function to some vehicle of having relatively high expectations, and increase drag angle if adjust prescription, then can have influence on other important performances of product.
The model utility content
The technical problem that the utility model mainly solves provides a kind of radial mode control arm rubber hydraulic bushing, can make the damping peak value of hydraulic bushing can reach more than 60 °, has greatly strengthened the vibration-damping noise-reducing effect, has improved the NVH characteristic of suspension system.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of radial mode control arm rubber hydraulic bushing is provided, comprise: outer aluminum component, lining and runner, outer aluminum component is loop configuration and the periphery that is coated on lining, and described lining is followed successively by from inside to outside: interior pipe, rubber body and outer ring, between pipe and the outer ring, described runner was radial runner knot in described runner was arranged at.
In preferred embodiment of the utility model, described outer ring and interior pipe are cast aluminium forming.
In preferred embodiment of the utility model, be filled with viscous liquid in the described runner, described viscous liquid is polyethyleneglycol.
In preferred embodiment of the utility model, described rubber body adopts caoutchouc vulcanization to form.
The beneficial effects of the utility model are: the utility model has used the radial flow passage structure in control arm rubber hydraulic bushing, when the imbalance excitation of control road surface and wheel, make drag angle reach desirable scope, reduced vibration and noise, improved the NVH characteristic of automobile.
