Description
Technical field
The utility model belongs to Automotive Steering Technology field, relates to a kind of lower swing arm assembly.
Background technology
Automobile lower suspension arm assembly, between auto body and wheel flutter, it is suspension main guide rod part, propelling rod effect can also be played, bear startup, braking, longitudinal force during turning and transverse force, it is one of major part determining vehicle performance, automobile lower suspension arm assembly end is connected with ball pin, ball pin is connected with other parts, the radical function of ball end realizes wheel bob and divertical motion, the leak tightness of dust boot affects very large on the wearing and tearing of ball end and fatigue life, but dust boots very much not most at present all adopts repeatedly bending to design, realize disperseing the stressed possibility reaching Reducing distortion, dust boot is the design of seldom taking after ball pin connects to reinforce, therefore in use rise and often can deform, dust is caused to enter ball end from fitting surface, on the wearing and tearing of ball end and impact fatigue life very large.
And because automobile to cause the vibration of wheel at rough road traveling, vibration easily makes existing lower swing arm assembly weld and does not closely locate distortion, and after long-time, lower swing arm there will be slight crack, affect the normal traveling of vehicle, reduces the safety of vehicle use.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides dust boot good airproof performance, lower swing arm assembly that lower swing arm weldment structural strength is high.
The utility model deal with problems adopt technical scheme be:
A kind of lower swing arm assembly, it comprises ball pin assembly, rubber bush and the lower swing arm connecting rod both connection, described ball pin assembly comprises ball pin, upper ball base and lower ball base is provided with bottom described ball pin, described upper ball base and lower ball base match and are formed with the container cavity holding ball pin, described upper ball base and lower ball base are placed on bottom, described upper ball base is outside equipped with housing, the clamping of dust boot one end on the housing and reinforced by large snap ring, the other end of described dust boot and ball pin top snug fit, and this end inside is provided with stage clip circle, the cross section of described dust boot is in " 7 " font, also protective cover is provided with outward at dust boot, the described dust boot back side is provided with the reinforced rib of a projection, this reinforced rib touches with protective cover contacted inner surfaces and coordinates, described lower swing arm connecting rod side is provided with brace panel.
In above-mentioned a kind of lower swing arm assembly, described lower swing arm connecting rod is symmetrically arranged with arch projection up and down, between two arch projections, forms a through hole.
In above-mentioned a kind of lower swing arm assembly, described brace panel is provided with knock hole.
In above-mentioned a kind of lower swing arm assembly, described knock hole has 2 at least.
The beneficial effects of the utility model are: the utility model is by being provided with stage clip circle at dust boot and ball pin junction, strengthen both laminating degree, and dust boot Cross section Design becomes 7 fonts, the dust boot back side is coordinated to be designed with the reinforced rib compressed mutually with protective cover inner face, make the laminating of dust boot and ball pin more stable and tightr, add the ground floor buffer action of exterior protection cover, effectively prevent dust from entering ball pin inside by fitting surface, reduce wearing and tearing, improve the service life of product, and, lower swing arm connecting rod is provided with brace panel, add the structural strength of connecting rod, arch projection on connecting rod can weaken the stressed probability causing being out of shape in side, multiple knock hole be designed to the stability strengthening connecting rod further, improve the use safety of vehicle.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the upward view of Fig. 1.
In figure: 1, rubber bush, 2, lower swing arm connecting rod, 21, brace panel, 22, knock hole, 23, arch projection, 24, through hole, 3, bottom, 4, lower ball base, 5, upper ball base, 6, large snap ring, 7, dust boot, 71, reinforced rib, 8, protective cover, 9, ball pin, 10, housing, 11, stage clip circle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail
As Fig. 1, shown in Fig. 2, a kind of lower swing arm assembly, it comprises ball pin assembly, rubber bush 1 and the lower swing arm connecting rod 2 both connection, described ball pin assembly comprises ball pin 9, upper ball base 5 and lower ball base 4 is provided with bottom described ball pin 9, described upper ball base 5 and lower ball base 4 match and are formed with the container cavity holding ball pin 9, described upper ball base 5 and lower ball base 4 are placed on bottom 3, described upper ball base 5 is outside equipped with housing 10, dust boot 7 one end to be connected on described housing 10 and to be reinforced by large snap ring 6, and this is the structure design of current most of lower swing arm assembly.
The improvement of this case is: the other end of described dust boot 7 and ball pin 9 top snug fit, and this end inside is provided with stage clip circle 11, strengthen the laminating degree of dust boot 7 and ball pin 9, the cross section of described dust boot 7 is in " 7 " font, protective cover 8 is also provided with outside dust boot 7, described dust boot 7 back side is provided with the reinforced rib 71 of a projection, this reinforced rib 71 touches with protective cover 8 contacted inner surfaces and coordinates, in use, this design can stop radially wobbling of ball pin 9, and strengthen the laminating degree of dust boot 7 and ball pin 9 further, add the ground floor buffer action of exterior protection cover 8, effectively prevent dust from entering ball pin 9 inside by fitting surface, reduce wearing and tearing, improve the service life of product.
