Two convex ribs are stamped on the plane of the outer connecting sleeve, the area of each convex rib is small, the flatness is easy to guarantee, the upper planes of the two convex ribs are attached to the plane of the vehicle body sheet metal part during loading, and abnormal sound caused by uneven attachment of a large plane is effectively avoided; meanwhile, the planeness of the matching surface is easily ensured by the optimized outer connecting sleeve, a rubber gasket is omitted, the part cost and the assembly labor cost of the part are reduced, and the production efficiency is improved.
Description
Technical Field
The utility model relates to a shock absorber technical field especially relates to a front strut assembly of outer coupling sleeve structure and independent suspension shock absorber.
Background
As shown in fig. 3, when the independent suspension type front pillar assembly is loaded, the plane of the outer coupling sleeve is required to be completely attached to the plane of the sheet metal part of the vehicle body, so that abnormal sound caused by uneven attachment in the driving process can be avoided. In fact, the external coupling sleeve and the sheet metal part cannot be absolutely flat, so that a rubber gasket is additionally arranged between the external coupling sleeve and the sheet metal part to eliminate abnormal sound generated by uneven fitting, as shown in fig. 1 and 2. But this construction directly increases the cost of a rubber gasket. Therefore, the external coupling sleeve structure is improved. The flatness of the matching surface of the existing external connecting sleeve is difficult to ensure, and a rubber gasket needs to be assembled, so that the cost is high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defects, the utility model aims to provide a rubber gasket which is cancelled, thereby meeting the loading performance; when loading, the upper planes of the two convex ribs are attached to the plane of the sheet metal part of the vehicle body, so that the flatness is ensured, and the outer coupling sleeve structure and the front pillar assembly of the independent suspension shock absorber, which generate abnormal sound due to uneven attachment of a large plane, are effectively avoided.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the technical scheme is that the outer coupling sleeve structure comprises an outer coupling sleeve; symmetrical convex ribs are arranged on the joint surface of the outer coupling sleeve and the sheet metal part of the automobile body.
Preferably, the two ribs are centrosymmetric.
Further preferably, the convex rib is perpendicular to the connecting axis of the two connecting bolt holes on the outer coupling sleeve.
More preferably, the rib is arc-shaped.
More preferably, the rib is formed by press forming.
Further preferably, the height of the convex rib is not more than 0.5mm, and the width of the upper plane of the convex rib is not more than 2 mm.
Another aspect provides an independent suspension shock absorber front strut assembly including the above outdrive configuration.
The beneficial technical effects are as follows:
two convex ribs are stamped on the plane of the outer connecting sleeve, the area of each convex rib is small, the flatness is easy to guarantee, the upper planes of the two convex ribs are attached to the plane of the vehicle body sheet metal part during loading, and abnormal sound caused by uneven attachment of a large plane is effectively avoided; meanwhile, the planeness of the matching surface is easily ensured by the optimized outer connecting sleeve, a rubber gasket is omitted, the part cost and the assembly labor cost of the part are reduced, and the production efficiency is improved.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In an embodiment, as shown in fig. 4 and 5, the present invention is an outer sleeve structure, including an outer sleeve 1; symmetrical convex ribs 3 are arranged on the binding surface of the outer coupling sleeve 1 and the sheet metal part of the vehicle body.
The two convex ribs 3 are centrosymmetric.
The convex rib 3 is vertical to the connecting axis of the two connecting bolt holes on the outer coupling sleeve 1.
The convex rib 3 is arc-shaped.
The convex rib 3 is formed by punching.
The height of protruding muscle 3 is not more than 0.5mm, and the last plane width of protruding muscle 3 is not more than 2mm, and protruding muscle 3 area is little, guarantees the plane degree easily, with two protruding muscle on the plane laminate with automobile body sheet metal component plane during the loading.
The front pillar assembly of the independent suspension shock absorber comprises the outer coupling shaft sleeve structure.
In the independent suspension type shock absorber for the vehicle, the function of the external connecting sleeve is as follows: the shock absorber is fixed with a vehicle body sheet metal part through a connecting bolt, so that the upper connection of the shock absorber and the vehicle body is realized. The improved outer connecting sleeve 1 is used for stamping two convex ribs 3 on the upper plane, the area of each convex rib 3 is small, the flatness is easily guaranteed, the upper planes of the two convex ribs are attached to the plane of a sheet metal part of an automobile body during loading, and abnormal sound caused by uneven attachment of the large planes is effectively avoided. Meanwhile, the planeness of the matching surface is easily ensured by the optimized outer connecting sleeve, a rubber gasket is omitted, the part cost and the assembly labor cost of the part are reduced, and the production efficiency is improved.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
