The utility model discloses an innovative design to the ripple cover interlude for the ripple cover interlude atress extends earlier or compresses when the dust cover moves, thereby has avoided the whole distortion of dust cover, and the while is improving the assembly firmness with the bumper shock absorber at the radial flanging of big footpath assembly portion shaping, is difficult for droing.
Description
Technical Field
The utility model relates to a prevent shock absorber dust cover of motion deformation belongs to the automobile parts field.
Background
The dust cover of the automobile shock absorber is a part arranged on the shock absorber of an automobile chassis, and mainly plays roles of dust prevention, impurity prevention, water isolation, temperature isolation and noise isolation, and the quality of the dust cover directly influences various working states of the shock absorber, so that the sealing performance and the noise level of the whole automobile are influenced. The assembly of bumper shock absorber dust cover is on chassis bumper shock absorber, and telescopic motion is along with the bumper shock absorber, and distortion appears easily in current bumper shock absorber dust cover to produce abnormal sound and wear out and decrease, reduce and even lose sealed isolation effect, current bumper shock absorber dust cover is not firm enough with the bumper shock absorber assembly simultaneously, drops easily under dynamic operating mode, exists not enoughly.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned insufficiency, the utility model provides a shock absorber dust cover that prevents motion deformation, the utility model discloses a technical scheme as follows:
a shock absorber dust cover for preventing motion deformation comprises a corrugated cover, a large-diameter assembly part and a small-diameter assembly part, wherein the large-diameter assembly part and the small-diameter assembly part are integrally formed at two ends of the corrugated cover in a blow molding mode; the wall thickness of the wave trough of the corrugated cover is greater than that of the wave crest of the corrugated cover, the inner diameter of the wave trough of the middle section of the corrugated cover is less than that of the wave troughs at two ends of the corrugated cover, the axial distance of the waves at the middle section of the corrugated cover is greater than that of the waves at two ends of the corrugated cover, and the wall thickness of the waves at the middle section of the corrugated cover is less than that of the waves at two ends of the corrugated cover; the end face of the large-diameter assembly part is integrally blow-molded with a radial outward flanging.
Further, 4 oblong holes are circumferentially and equidistantly formed in the side wall of the large-diameter assembling portion.
Further, 4 hook-shaped grooves and 4 circular grooves are arranged on the port of the small-diameter assembling portion in a circumferentially equidistant and crossed mode.
Furthermore, the side wall of the small-diameter assembly part is circumferentially and equidistantly provided with concave reinforcing structures with rhombic orthographic projections.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a do the innovative design to ripple interval, wall thickness and the trough degree of depth of ripple cover interlude for the earlier atress of ripple cover interlude extends earlier or compresses when the telescopic movement is along with the bumper shock absorber, thereby has avoided the whole distortion of dust cover. The utility model discloses a at the radial flanging of big footpath assembly portion shaping, when the spring upper support with the bumper shock absorber with fill up the pressure equipment on, the interference degree is big, the pressure equipment area is big to improved the assembly firmness with the bumper shock absorber, be difficult for droing.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic sectional view of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1-2, a shock absorber dust cover for preventing motion deformation includes a bellows 1, and a large-diameter fitting part 2 and a small-diameter fitting part 3 integrally blow-molded at both ends of the bellows 1; the wall thickness of the wave trough of the corrugated cover 1 is greater than that of the wave crest of the corrugated cover 1, the inner diameter of the wave trough of the middle section 10 of the corrugated cover 1 is less than that of the wave troughs at two ends of the corrugated cover 1, the axial distance of the corrugations of the middle section 10 of the corrugated cover 1 is greater than that of the corrugations at two ends of the corrugated cover 1, and the wall thickness of the corrugations of the middle section 10 of the corrugated cover 1 is less than that of the corrugations at two ends of the corrugated cover 1; the end surface of the large-diameter assembly part 2 is integrally blow-molded with a radial outward flange 20.
Further, 4 oblong holes 21 are circumferentially and equidistantly arranged on the side wall of the large-diameter assembling part 2.
Further, the port of the small-diameter fitting portion 3 is provided with 4 hook-shaped grooves 30 and 4 circular grooves 31 which are circumferentially and equidistantly intersected.
Further, the side wall of the small-diameter assembling portion 3 is circumferentially provided with concave reinforcing structures 33 with regular projections in a diamond shape at equal intervals.
The utility model discloses a do the innovative design to ripple interval, wall thickness and the trough degree of depth of ripple cover interlude for the earlier atress of ripple cover interlude extends earlier or compresses when the telescopic movement is along with the bumper shock absorber, thereby has avoided the whole distortion of dust cover. The utility model discloses a at the radial flanging of big footpath assembly portion shaping, when the spring upper support with the bumper shock absorber with fill up the pressure equipment on, the interference degree is big, the pressure equipment area is big to improved the assembly firmness with the bumper shock absorber, be difficult for droing.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
