Detailed Description

As shown in fig. 1 and 2, fig. 1 is a schematic structural view of a lightweight plastic bushing for an automobile according to the present invention, and fig. 2 is a schematic structural view of a lightweight plastic bushing for an automobile according to the present invention as viewed from above.

Referring to fig. 1 and 2, the present invention provides a lightweight plastic bushing for an automobile, including: a sleeve body 1;

the sleeve body 1 is of a cylindrical structure made of engineering plastics, a plurality of grooves 2 distributed annularly are formed in the outer wall of the sleeve body 1, a plurality of bulges 3 distributed annularly are formed in the inner wall of the sleeve body 1, and each groove 2 corresponds to one bulge 3.

In this embodiment, the proposed lightweight plastic bushing for an automobile has a cylindrical structure made of engineering plastic, the outer wall of the bushing body is provided with a plurality of annularly distributed grooves, the inner wall of the bushing body is provided with a plurality of annularly distributed protrusions, and each groove corresponds to one protrusion. Through above-mentioned lightweight plastics bush for car of optimal design, simple structure, the contour machining of being convenient for adopts the engineering plastics that contains glass fiber to replace metal material, through recess and bellied rational arrangement on the lateral wall, has effectively alleviateed the weight, satisfies the intensity requirement of use operating mode simultaneously.

In the using environment of the bushing, the requirement on the mechanical strength of the bushing is high, and the requirement on the dynamic and static rigidity needs to be met, so that in the specific material selection, the bushing body 1 is made of PA66 containing 25% -35% of glass fiber, and can be integrally formed by injection molding during processing.

In the specific embodiment of the sleeve body structure, the outer wall of the sleeve body 1 is provided with a plurality of annularly distributed concave parts, and each concave part is provided with a plurality of grooves 2; set up a plurality of depressed areas along the circumference on the cover body, every depressed area has a plurality of recesses, is convenient for according to the cover body service behavior, designs the groove distribution of different positions, guarantees to support intensity and elastic balance.

In a further embodiment, a plurality of grooves 2 are distributed in an array along the axial direction of the jacket body 1.
