Description
Technical field
The utility model belongs to absorber technical field, and specifically, the utility model relates to a kind of Dustproof device of shock absorber.
Background technique
Common two kinds of the damper structure of car rear axle: one is end band suspension ring, and the other end is connected to vehicle body by nut; Another kind is two ends is all suspension ring structure, is connected respectively by the structure of suspension ring with wheel shaft with vehicle body.Usually, the vibration damper of the second structure is produced at car load and was assembled in title, simple and easy, fast, and easy accessibility during maintenance.
For two suspension ring vibration damper, adding the technique man-hour welding procedure of dust-proof cover and cover cap and damper surface being made to protective layer, generally take the practice of first four spot welding, rear spraying at present both at home and abroad.Because welding will be conducted electricity, therefore the dust-proof cover inner and outer surface of low carbon steel can not make conservation treatment, but after welding; because spraying can only be sprayed onto the surface of dust-proof cover; therefore the inwall of dust-proof cover is not having in surface-treated situation, outside being exposed to, does not meet the life requirements of product.And this technique must be possess four spot welding machines and spraying equipment.
Model utility content
The utility model provides a kind of Dustproof device of shock absorber, and object improves quality.
To achieve these goals, the technological scheme that the utility model is taked is: a kind of Dustproof device of shock absorber, the cover cap comprising dust-proof cover and insert in dust-proof cover, described dust-proof cover comprises cover body and bound edge portion, the sidewall of cover body is provided with and protrudes towards inner side and bulge loop to described cover cap axial limiting, the end edge that bound edge portion is located at cover body along and compress cover cap.
Described bulge loop is the ring of the whole circumference extension along described cover body, and bulge loop is near the end of cover body.
The inner side surface of described bulge loop is arc surface.
The outer side surface place of described bulge loop forms the groove of a ring.
Described bound edge portion is the structure of whole end edge along extension and for bending towards described cover cap place along described cover body.
The end that described cover cap inserts in described cover body has chamfering.
The utility model Dustproof device of shock absorber, by arranging bulge loop and bound edge portion matches on dust-proof cover, cover cap is fixed on dust-proof cover, both connect reliable, the dust guard quality formed is good, press mounting structure fully can ensure the coaxality of dust-proof cover and cover cap and dust-proof cover and damper main body, and is convenient to optimization and the improvement of preparation process; And adding man-hour, can cancel spraying process, dust-proof cover by making internal surface and outer surface all form protective layer from the mode of swimming, thus can improve the working life of product.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail embodiment of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technological scheme, and contribute to its enforcement.
As shown in Figures 1 to 4, a kind of Dustproof device of shock absorber of the utility model, the cover cap 4 comprising dust-proof cover 3 and insert in dust-proof cover 3, dust-proof cover 3 comprises cover body 31 and bound edge portion 33, the sidewall of cover body 31 is provided with and protrudes towards inner side and bulge loop 32 to cover cap 4 axial limiting, the end edge that bound edge portion 33 is located at cover body 31 along and compress cover cap 4.Bound edge portion 33 is axial for being oppositely arranged along cover body 31 with the bulge loop 32 in cover body 31, both match and can be fixed on dust-proof cover 3 by cover cap 4, guarantee that cover cap 4 is connected with dust-proof cover 3 reliably, cover cap 4 is beated less and good stability, ensure the coaxality that cover cap 4 and dust-proof cover 3 assemble to improve the quality of product of dust guard.
Specifically, the cover body 31 of dust-proof cover 3 is the circular tube shaped component that length is longer, and the sidewall of cover body 31 has certain rear end, near the position of end arranging bound edge portion 33 on the sidewall that bulge loop 32 is positioned at cover body 31.
As preferably, as shown in Figure 3, bulge loop 32 is the ring extended along the whole circumference of cover body 31, and stretches out towards cover body 31 center for the radial direction along cover body 31.The minimum diameter at bulge loop 32 place is less than the external diameter of cover cap 4, thus can play position-limiting action.Bulge loop 32 adopts to produce the mode that dust-proof cover blank extrudes, and the inner side surface of the bulge loop 32 of corresponding formation is arc surface, and forms the groove of a ring at the outer side surface place of bulge loop 32.
As preferably, as shown in Figure 3, bound edge portion 33 is the structure of whole end edge along extension and for bending towards cover cap 4 place along cover body 31, and corresponding bound edge portion 33 is solid of rotation, the internal surface of the circular arc in bound edge portion 33 and the outer surface of cover cap 4 are fitted, and are pressed in cover body 31 by cover cap 4.
Bound edge portion 33 on dust-proof cover 3 is press-fiting in cover cap 4 process, is extruding simultaneously to the end of dust-proof cover blank, after suppressing bound edge portion 33, cover cap 4 can be pressed on dust-proof cover 3.
As shown in Figure 1, cover cap 4 is enclosed within the piston rod 2 of damper main body, adjacent with suspension ring 1 position of piston rod 2 end.As shown in Figure 4, cover cap 4 is solid of rotation, and it comprises cone part 43, annular portion 42 and trunk portion 41, the structure of cone part 43 in taper type, the structure of annular portion 42 in ring, the cylindrical structure of trunk portion 41, annular portion 42 is between cone part 43 and trunk portion 41, and three is coaxial.The inward flange of annular portion 42 and the bigger diameter end edge conjunction of cone part 43, the outward edge of annular portion 42 is connected with one end of trunk portion 41, and is arc transition between annular portion 42 and trunk portion 41.
The inner diameter equal and opposite in direction of the outer diameter size of the trunk portion 41 of cover cap 4 and the cover body 31 of dust-proof cover 3, trunk portion 41 is inserted in cover body 31, further ensures the coaxality of dust-proof cover 3 and cover cap 4.As shown in Figure 2, the bound edge portion 33 on dust-proof cover 3 contacts with cover cap 4 with the arc transition position between trunk portion 41 in the annular portion 42 of cover cap 4, is convenient to bound edge portion 33 on the one hand compressing, guarantees that cover cap 4 is installed reliably on the other hand.
As shown in Figure 4, the outer side surface place, end of the trunk portion 41 of cover cap 4 has chamfering 44, and cover cap 4 contacts with bulge loop 32 at chamfering 44 place.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; Or without improvement, above-mentioned design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model.
