Abstract
The utility model relates to a shock absorption device for motor vehicles, particularly, the improvement of the structures of a dustproof vibration damper, etc. The shock absorption device for motor vehicles mainly solves the technical problems that the fabrication of the existing bumping block and a dustproof cover are separated in the prior art; dust can fall into a vibration damper from a gap between the bumping block and the dustproof cover; the fabrication of the shock absorber is relatively cockamamie, and the assembly of the shock absorber is relatively complicated, etc. The utility model comprises a cylinder body (1), wherein the inner side of the cylinder body (1) is provided with a piston rod (2); one end of the cylinder body (1) is connected with a dustproof cover (3); the outer side of the cylinder body (1) is connected with a pressure spring (4); a rod body of the piston rod (2) is accompanied by the bumping block (5); the outer side of the bumping block (5) is provided with a casing (6); one end of the piston rod (2) is connected with an outer joining sleeve (7). The utility model is characterized in that one end of the dustproof cover (3) is connected to the bumping block (5).
Description
Technical field
The utility model relates to a kind of Motor Vehicle shock-absorption device, especially relates to a kind of to the dustproof isostructural improvement of vibration damper.
Background technique
Automobile absorber comprises the cylinder body of being with piston cylinder, the end cap that cooperates with cylinder body, one end places piston rod and close-fitting wiper seal of piston rod and the guide holder in the cylinder body, and the rectangular seal that cooperates with guide holder is positioned at the lining of asking of guide holder and piston rod etc.Chinese patent discloses a kind of automobile absorber (publication number: CN 2178807Y), it includes cylinder body, one end places the piston rod in the cylinder body, the end cap equipped with cylinder body, place be contained in the cylinder body on the piston rod with the close-fitting wiper seal of piston rod, guide holder, be pressed on the lining in the guide holder, the preceding guide holder that is contained on the piston rod is arranged between end cap and wiper seal, the front lining before being pressed in the guide holder.Chinese patent discloses a kind of dust prevention of vibration absorber sheath (publication number: CN 2414939Y) again, its composition comprises body, body is that macromolecular material is made, perpendicular to the sectional shape in the section of body center line be annular, its outer surface matches with vibration damper loam cake endoporus, and have with vibration damper on the annular ditch that is nested of the projection that covers, it is consistent that the last hole and the shock absorber piston of body connects the pavilion diameter, the lower end diameter of body is sealed up lid with shock absorber fluid and is matched.But these two kinds of structures are assembled more complicated because the buffer stopper of vibration damper the inside separates making with dust-proof cover, and dust can be fallen into vibration damper inside from the slit between buffer stopper and the dust-proof cover, and production is more loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides a kind of dustproof vibration damper, it mainly is to solve the existing in prior technology buffer stopper to separate making with dust-proof cover, dust can be fallen into vibration damper inside from the slit between buffer stopper and the dust-proof cover, and production is more loaded down with trivial details, the technical problem of assembling more complicated etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Dustproof vibration damper of the present utility model, comprise cylinder body, be provided with piston rod in the cylinder body, cylinder body one end is connected with dust-proof cover, cylinder body is externally connected with stage clip, and with buffer stopper, buffer stopper is provided with housing outward on the body of rod of piston rod, piston rod one end is connected with outer joint sleeve, it is characterized in that an end of described dust-proof cover is connected on the buffer stopper.Outer connection puts and is provided with bolt, is convenient to vibration damper and is installed on the vehicle suspension.Dust-proof cover and buffer stopper are joined together to form the integrated type press resistant pillar, make comparatively simply, help to prevent that dust from entering vibration damper inside.
As preferably, stage clip one end is connected on the cylinder body, and the other end is connected on the housing.Stage clip can not have influence on the dust-proof cover torsional deformation when compression.
As preferably, be connected with plane bearing between described housing and the outer joint sleeve, reduced the inter deterioration of vibration damper.
Therefore, the utlity model has buffer stopper and dust-proof cover is made into one, dust can not fallen into vibration damper inside from the slit between buffer stopper and the dust-proof cover, and characteristics such as production, assembling are fairly simple, and be rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the dustproof vibration damper of this example, as Fig. 1, there is an end to be provided with the cylinder body 1 of stop collar, be provided with piston rod 2 in the cylinder body, the piston rod end is connected with outer joint sleeve 7 by bolt, and outer connection puts and is connected with bolt.With buffer stopper 5, an end of the dust-proof cover 3 of tubular is connected on the buffer stopper 5 on the body of rod of piston rod 2, forms the integrated type press resistant pillar.Be provided with housing 6 outside the buffer stopper 5, be connected with plane bearing 8 between housing 6 and the outer joint sleeve 7, can prevent the vibration damper wearing and tearing.Be connected with stage clip 4 on the outer wall of cylinder body 1, stage clip 4 the other ends are connected on the housing 6.
During use, outer joint sleeve 7 is installed on the automotive suspension injection pressure oil in the cylinder body 1.When Motor Vehicle is given a shock, stage clip 4 compressions, because the effect of buffer stopper, vibration damper can be eliminated vibrations.Because dust-proof cover 3 becomes the integrated type press resistant pillar with buffer stopper 5 integral manufacturings, can prevent that dust from entering vibration damper inside.
