Abstract
The invention discloses an automotive bush. The automotive bush comprises an inner metal barrel, an outer metal barrel, rubber and an inner framework, wherein the rubber is positioned between the inner metal barrel and the outer metal barrel; the inner framework is trapezoidal; included angles between both sides of the inner framework and the axle center of the inner metal barrel are 30-60 degrees; the inner framework is arranged in the inner metal barrel; the outer metal barrel is provided with a flange; the inner metal barrel, the outer metal barrel, the inner framework and the rubber are all revolving bodies. The automotive bush is simple in structure; the included angle between the inner framework and the axle center of the inner metal barrel is set to be 30-60 degrees, and the outer metal barrel is provided with the flange, so that bonding of the metal barrels and the rubber is facilitated, and reduction of the yield caused by mold contraction is avoided.
Description
Technical field
The present invention relates to auto parts and components, especially a kind of automobile lining.
Background technique
Lining is widely used in automobile, construction machinery industry, especially automobile industry, as automobile balance bars, control arm, pull bar and autobody sheet etc., automobile lining plays sealing, buffer function, during existing lining is produced, for rubber bushing, adopt Shooting Technique, injection moulding adopts thermoplastics type, and particle enters mould through high-pressure flow, now shrink serious, some bush inside are metal, and outside is rubber, and adhesion of rubber to metal needs uniform temperature and time response, this kind of structure lining is not easily produced, and rate of good product is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of automobile lining, and new structure makes the lining rate of good product of production high.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of automobile lining, comprise interior metal cylinder, outer metal cylinder and rubber, described rubber is between interior metal cylinder and outer metal cylinder, also comprise inner frame, described inner frame is trapezoidal, and both sides and the interior metal cylinder axle center angle of described inner frame are 30 ° ~ 60 °, and shown inner frame is arranged in interior metal cylinder, described outer metal cylinder is provided with flange, and interior metal cylinder, outer metal cylinder, inner frame and rubber are solid of rotation.
Further, described outer metal cylinder is shorter than rubber, and wherein, outer metal cylinder flange place and rubber one end distance are 15mm ~ 20mm, and outer metal cylinder opposite side and rubber the other end distance are 10mm.
Preferably, described inner frame is quality of rubber materials or metal.
The invention has the beneficial effects as follows:
Structure of the present invention is simple, and inner frame and interior metal cylinder axle center angle are set to 30 ° ~ 60 °, and outer metal cylinder arranges flange, facilitates the bonding of metal cylinder and rubber, and the rate of good product avoiding mold shrinkage to bring reduces.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is a kind of automobile lining of the present invention schematic diagram.
Fig. 2 is that a kind of automobile lining of the present invention A-A is to sectional view.
In figure: 1, outer metal cylinder, 2, rubber, 3, interior metal cylinder, 4, inner frame.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, the present invention discloses a kind of automobile lining, comprise interior metal cylinder 3, outer metal cylinder 1, inner frame 4 and rubber 2, described rubber 2 is between interior metal cylinder 3 and outer metal cylinder 1, described inner frame 4 is trapezoidal, both sides and the interior metal cylinder 3 axle center angle of described inner frame 4 are 30 ° ~ 60 °, in the present embodiment, angle is 60 °, shown inner frame 4 is arranged in interior metal cylinder 3, described outer metal cylinder 1 is provided with flange, and interior metal cylinder 3, outer metal cylinder 1, inner frame 4 and rubber 2 are solid of rotation.
As shown in Figure 2, described outer metal cylinder 1 is shorter than rubber 2, and wherein, outer metal cylinder 1 flange place and rubber 2 one end distance are 15mm ~ 20mm, and outer metal cylinder 1 opposite side and rubber 2 the other end distance are 10mm.
Described inner frame 4 is quality of rubber materials or metal.
Designed by the flange of outer metal cylinder 1, and the angle design of inner frame, make aborning, the automobile lining that the method adopting injection moulding to combine with casting is produced, rate of good product is high.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
