Automobile swing arm assembly is applied in the suspension of automobile chassis, and the structural style of automobile swing arm assembly is a lot, has different swing arm assembly structures for different automobile types.The open type automobile swing arm assembly of prior art, bulb assembly and bush assembly are generally installed on swing arm, the structure of bulb assembly is compared with Complex Assembly inconvenience, the easy clamping stagnation of bulb action, dust-proof unreliable, and the damping performance of bush assembly is poor, also have, swing arm is usually ironcasting or metal welding fitting, and Heavy Weight intensity is short of.
Summary of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide that a kind of simple in construction is easy to assembly, bulb flexible movements, has the open type automobile swing arm assembly of reliable damping dust-proof effect.
This utility model has adopted the following technical scheme that:
nullOpen type automobile swing arm assembly，Including strip swing arm，Bulb assembly is installed in the upper end of swing arm，Bush assembly is installed in lower end，It is characterized in that: swing arm is aluminum alloy die casting，The upper end of swing arm is provided with installing hole，Described bulb assembly includes ball seat、Ball stud and blanking cover，The bulb of ball stud loads upper installing hole from the backside openings of upper installing hole after loading ball seat together with ball seat，Then in upper installing hole, load described blanking cover，The bottom surface of ball seat is provided with cyclic spring groove，The backside openings of described upper installing hole is provided with after blanking cover and ball seat are compressed by in-flanges spacing in upper installing hole，The bearing pin of described ball stud passes outward from the front openings of upper installing hole，Bearing pin is by path axostylus axostyle、Big footpath cylinder and conical section are sequentially connected with composition，The little head end connecting ball head of cone，The outer round surface of big footpath cylinder is provided with draw-in groove，The front openings of described upper installing hole is covered by dust cover，In the lower port of dust cover embraces the annular groove being located at installing hole outer rim and carry out banding by lower collar，The upper port of dust cover is embraced in being located at described draw-in groove and carries out banding by upper collar，The root of path axostylus axostyle is fixed sheathed catch and is carried out protecting by the upper port of dust cover.
In technique scheme; bulb assembly is directly mounted in the upper installing hole of swing arm; it is not required to additionally arrange spherical shell; simple in construction, easy to assembly; and designed by optimization; it is provided with cyclic spring groove in the bottom surface of ball seat; so after blanking cover and ball seat are compressed by the in-flanges of installing hole backside openings; by the elastic deformation that ball seat is suitable, bulb can be made still to swing with the shaking moment set in ball seat, bulb flexible swinging; reliable in action; it addition, dust cover is protected, dust cover dust-proof reliably；Further, swing arm uses aluminum alloy die casting, and lightweight intensity is high.
As preferably, the outside of described dust cover is provided with protective cover, and the lower port flare of protective cover covers the lower port of described dust cover, and the inner side of the upper port of protective cover is provided with dividing plate, and the endoporus of dividing plate holds the path axostylus axostyle cylindrical being located at described bearing pin tightly.Above-mentioned design improves dust-proof effect.
As preferably, the lower end of swing arm is provided with lower installing hole, described bush assembly is made up of lining outer tube, lining inner tube, vulcanite and lining skeleton, lining outer tube press-fits and is fixed in described lower installing hole, lining skeleton is embedded in vulcanite, it is recessed that the two side ends face of the vulcanite between lining skeleton and lining outer tube is inwardly recessed formation first, and it is recessed that the two side ends face of the vulcanite between lining skeleton and lining inner tube is inwardly recessed formation second.Being designed by above-mentioned optimization, the resisting fatigue damping performance of bush assembly is more preferable, improves service life.
