Abstract
The invention relates to an upper swinging arm structure of a suspension frame. The upper swinging arm structure comprises an upper swinging arm body and a bush installing hole fixedly connected with the upper swinging arm body, wherein the upper swinging arm body is of an integrated structure. A fork-type upper swinging arm structure is formed at a steering-knuckle installing hole of the upper swinging arm body; one end surface of the long edge of the upper swinging arm body is overturned towards the other end surface.
Description
Technical field
The invention belongs to auto body field, refer to a kind of Motor Vehicle Independent Suspension System, refer to especially a kind of suspension top link structure.
Background technology
After suspension, top link is the distinctive structure of independent suspension, and its effect is to determine wheel Installation posture together with lower swing arm.
Excessive or meet on the way while jolting at suspension system bearing load, spring generation deformation causes vehicle body and wheel relative position to change, and wheel self also can deform, for the wheel that guarantees that automotive suspension can meet operating needs, need top link to drive together with lower swing arm to be arranged on steering swivel rotates around the centre of gration of suspension.
As shown in Figure 1, traditional suspension top link is that inside also will be welded brace panel 4 and be guaranteed its intensity by upper plate 3 and 2 two pressing sheet material weld togethers of lower plate, and on then press-fiting in lining mounting hole 1, lining and ball pin realize and pivoting.Traditional suspension top link is by two or multi-sheets weld together after punch forming, and its shortcoming is that processing technology is complicated; It is more that a large amount of weld seams of welding process expend the energy; The pollution that welding process causes is more; Because sheet material use amount is larger, weight is heavier.
Summary of the invention
The object of the invention is the manufacture of traditional suspension top link to propose to improve technical scheme, adopt a sheet material, the techniques such as punching press without through numerous and diverse, have reduced energy consumption.
The present invention is achieved by the following technical solutions:
A suspension top link structure, includes top link body and the lining mounting hole being fixedly connected with top link body; Described top link body is structure as a whole.
Described top link body forms V shape top link structure from steering swivel mounting hole place; An end face on the long limit of described top link body is to other end turnup.
In the curve that radial section after described top link body turnup forms, when steering swivel mounting hole extends to lining mounting hole direction, the mean curvature of its curve increases.
After described top link body turnup, from steering swivel mounting hole, to lining mounting hole direction, the distance between the both ends of the surface of top link body reduces.
After described top link body turnup, from steering swivel mounting hole, to lining mounting hole direction, the curve that radial section forms is changed to sub-circular by approximate ellipsoidal.
Steering swivel mounting hole place in described top link body, the turnup amount of nearly steering swivel one end face is greater than the turnup amount of steering swivel one end face far away.
The described top link body part course of processing successively operation of process includes blanking, moulding, trimming, crimping, shaping, punching and hole flanging.
The invention has the beneficial effects as follows:
The benefit that the present invention directly brings, for having reduced component weight, has reduced operation and the energy resource consumption in production process, has reduced disposal of pollutants.
The present invention follows the principle of circular cross section, guarantees the intensity of swing arm.

The specific embodiment
By specific embodiment, describe technical scheme of the present invention in detail below, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As shown in Figures 2 to 5, the top link body base portion course of processing of the present invention only need to be passed through following operation successively: blanking, moulding, trimming, crimping, shaping, punching, hole flanging etc., because top link body only has a sheet material (as shown in Figure 2), without repeatedly processing respectively.
A suspension top link structure, includes top link body 5 and the lining mounting hole 7 being fixedly connected with top link body 5; Described top link body is structure as a whole.The top link body base portion course of processing does not need welding, has directly reduced the discharge of pollution and waste.
Described top link body forms V shape top link structure from steering swivel mounting hole 6 places; An end face on the long limit of described top link body is to other end turnup.Turnup in the present embodiment refers to by operations such as aforesaid blanking, moulding, trimming, crimping, shaping, punching, hole flangings, realizes the curly course of sheet material.
In the curve that radial section after described top link body turnup forms, when steering swivel mounting hole extends to lining mounting hole direction, the mean curvature of its curve increases, and sees respectively Fig. 3, Fig. 4 and Fig. 5.
After described top link body turnup, from steering swivel mounting hole, to lining mounting hole direction, the distance between the both ends of the surface of top link body reduces, and sees respectively Fig. 3, Fig. 4 and Fig. 5.
After described top link body turnup, from steering swivel mounting hole, to lining mounting hole direction, the curve that radial section forms is changed to sub-circular by approximate ellipsoidal, sees respectively Fig. 3, Fig. 4 and Fig. 5.
Steering swivel mounting hole place in described top link body, the turnup amount of nearly steering swivel one end face is greater than the turnup amount of steering swivel one end face far away.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
