Description
Technical Field
The utility model belongs to the technical field of control arm opening bush, concretely relates to two power pole control arm opening bushes of non-.
Background
Rubber bushings are an important component of automotive suspension systems, and their main functions include: the force and moment of the control arm and the vehicle body are transmitted, the high-frequency vibration transmitted by the control arm is attenuated, noise is reduced, and better elastic dynamic control is achieved by matching the rigidity in all directions. With the increasing temperature of the medium-sized and large-sized SUV markets, the spring and the damper are limited by spatial arrangement, so that the durability requirement of the control arm bushing is improved, the opening bushing can meet higher durability requirement due to excellent durability, but the opening direction of the opening bushing is low in rigidity and needs to be far away from the maximum stress direction of the inner point and the outer point of the control arm, so that better durability is provided.
Disclosure of Invention
For better solution above-mentioned problem, the utility model provides a two power pole control arm opening bush of non possess pass power, fall make an uproar, the requirement of vibration isolation outside, possess than the more excellent durability of ordinary bush.
The utility model discloses a concrete technical scheme as follows:
the utility model provides a non-two power pole control arm opening bush, include with control arm interference fit's bush outer tube 1 and with sub vehicle frame fixed connection's bush inner tube 3, bush outer tube 1 include outer pipe wall and rubber layer 2, the rubber layer 2 laminating is on the internal diameter of outer pipe wall, the equipartition has inserted sheet 4 in the rubber layer 2, the outer pipe wall of bush inner tube 3 by the rubber layer 2 cladding, the axial of bush outer tube 1 on seted up opening 5, opening 5's tolerance be 3 °
The beneficial effects are as follows:
the utility model has the advantages of bulk strength, rigidity increase, processing technology are advanced, the shock attenuation buffering effect is good, when assembling closely the degree increase, the good practical life of pliability is long.
The utility model discloses a remove undergauge and reaming technology from after the bush vulcanizes, can directly the pressure equipment at the armed lever mounting hole, only produce a small amount of plastic deformation that leads to because the interference pressure equipment after the installation to can design bigger rubber compression volume, improve durability and better comfort.

Fig. 2 is a cross-sectional view of the control arm opening bushing of the present invention.
Fig. 3 is a schematic diagram of the force applied to the control arm opening bushing according to the present invention.
Detailed Description
The invention is described in further detail with reference to the figures and the detailed description.
As shown in fig. 1 and 2, the utility model provides a two power pole control arm opening bush of non-, include with control arm interference fit's bush outer tube 1 and with sub vehicle frame fixed connection's bush inner tube 3, bush outer tube 1 include outer pipe wall and rubber layer 2, the rubber layer 2 laminating is on the internal diameter of outer pipe wall, the equipartition has inserted sheet 4 in the rubber layer 2, the outer pipe wall of bush inner tube 3 by the cladding of rubber layer 2, the axial of bush outer tube 1 on seted up opening 5, opening 5's tolerance be 3 degree
The common bushing process comprises the following steps: vulcanization-diameter reduction-press fitting of the control arm-control arm assembly, the purpose of diameter reduction is to eliminate the stretching caused by the rebound of the cooled rubber after vulcanization, and if diameter reduction is not carried out, the rubber is in a stretched state, which can reduce the durability of the bush
The process of the opening bushing comprises the following steps: in the vulcanization-press mounting-control arm assembly, the diameter of the opening bushing does not need to be reduced, the rubber springback generated by cooling after vulcanization is naturally eliminated after the bushing is pressed and mounted into the control arm, the pressed rubber is naturally in a compression state, and the rubber durability is better in the compression state.
As shown in fig. 2, the bearing spring in the middle of the control arm, the spring force F1 is downward all the time, the opening bushing side is connected with the sub-frame, the bushing inner tube is connected with the sub-frame through a bolt, the bushing outer tube is in interference fit with the control arm, the sub-frame is fixed, which is equivalent to the fact that the bushing inner tube is fixed, the bushing outer tube applies downward force to the bushing inner tube, the bushing outer tube receives upward force from the bushing inner tube, the opening direction of the bushing outer tube is far away from the stress direction, so the opening direction is downward, the tolerance is ± 3%, after the whole vehicle strengthening bad road test, the bushing is not damaged, and the.
In a similar way, the other side is connected with the steering knuckle, the opening bushing is pressed into the steering knuckle, the bushing outer pipe is fixedly connected with the steering knuckle, the inner pipe is connected with the control arm through the bolt, the bushing inner pipe applies downward force to the bushing outer pipe, the bushing outer pipe bears downward force, the opening direction of the bushing is far away from the stress direction, so that the tolerance is +/-3 degrees in the direction close to the rear direction, and after the whole vehicle reinforced bad road test, the bushing is not damaged, and the rigidity loss is less than 30 percent. The utility model provides an opening bush and control arm cooperation need follow certain standard of relating to.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
