Abstract
The invention aims to provide an upper oscillating arm assembly of an automobile double-wishbone suspension, which has the advantages of light weight, simple structure, low manufacture cost and convenience for installation. The upper oscillating arm assembly of the automobile double-wishbone suspension comprises an upper oscillating arm body provided with a ball pin assembly and is characterized in that two free ends of the oscillating arm body are connected by bolts; the upper oscillating arm body is subjected to punch forming by a single layer of steel plate; the cross section of the upper oscillating arm body is of a groove shape of which the opening faces upwards or downwards; and the opening of the groove shape is gradually reduced to free ends on two ends from the ball pin assembly.The upper oscillating arm assembly of the automobile double-wishbone suspension has the advantages of simple and reasonable structure, light weight, low manufacture cost and convenience for install and is very suitable to apply for low and medium-grade automobiles.
Description
Technical field
The invention belongs to the technical field of automobile front suspension, specially refer to a kind of pair of yoke suspension top link assembly.
Background technology
Existing pair of fork arm type equal suspension top link assembly mainly contains following several form: 1, a kind of to be the top link body formed by two metal plate punching seam up and down, top link body one side links to each other with the ball end assembly by bolt, opposite side press-fits by the mandrel of two bush Assemblies and forging molding, also need machine to add 2～3 mounting holes on the mandrel simultaneously, link to each other with vehicle body (or vehicle frame) by 2～3 bolts again; Adopt the top link assembly quality of this mode heavy, processing technology is complicated, and assembly process is loaded down with trivial details, and the non-suspended mass of suspension is relatively heavier, and the distortion of welding assembly is difficult to control, causes homogeneity of product poor.2, the second is that the top link body adopts casting processing, the ball end base is directly processed at the foundry goods body, the relative the first of this structure, punching press and welding deformation have been eliminated, but core shaft structure is not done any change, exist equally quality heavy, the shortcoming such as the relatively heavier and processing technology of the non-suspended mass of suspension is complicated.3, the third is that the top link body adopts cast aluminium or wrought aluminium, also cancelled simultaneously mandrel, although this structure can reduce quality and the non-suspended mass of product itself, but because domestic technique is still immature, and the processing technology difficulty is large, cost is high, be mainly used at present on the high-grade limousine, can't popularize at low and middle-grade cars temporarily.
Summary of the invention
The objective of the invention is to propose that a kind of quality is light, simple in structure, easy for installation, the automobile double yoke suspension top link assembly of low cost of manufacture.
Automobile double yoke suspension top link assembly of the present invention comprises the top link body that the ball end assembly is installed, and key is that two free ends of described top link body are bolted.The top link body has been cancelled the traditionally mandrel with mounting hole of swing arm structure, directly adopt an overbolt to link to each other with vehicle body (or vehicle frame), simplified the top link assembly structure, further reduced top link weight, manufacturing procedure and assembly technology have been simplified simultaneously, reduce the parts manufacturing cost, promoted car load production efficiency.
Further, described top link body adopts the moulding of individual layer steel plate punched, and the cross-sectional plane of top link body is opening upwards or downward flute profile, and the opening of this flute profile is reduced to the free end at two ends gradually by ball end assembly place.For the top link of body butt-welding type about one piece casting type reaches, weight can significantly reduce, and has reduced non-suspended mass, has promoted handling stability and the traveling comfort of vehicle.Opening upwards or downward flute profile can strengthen intensity and the rigidity of the vertical direction of top link body in addition, by optimizing how much patterns of top link body, can make the top link body form different the flexural factor of sections, under the prerequisite in proof strength, rigidity and service life thereof, make how much patterns at each position of top link body and the load Proper Match that is subject to.
Specifically, the cross sectional shape of the top link body at described ball end assembly place is flute profile, and a side of described bottom land has an additional groove, and this additional groove can further be strengthened the bearing capacity at ball end assembly place; The cross sectional shape of the top link body between ball end assembly place and the free end is flute profile, and the top of the both sides cell wall of described flute profile tilts to flute profile central authorities, with improve this place's fore-and-aft direction and left and right sides to intensity and rigidity; The cross sectional shape of the top link body of free end is circular, and described circle has breach, and therefore stressed maximum herein is designed to each and can satisfies its force request to the strongest circle of bending resistance.
Further, two free ends of described top link body adopt the interference mode to be pressed with lining, to improve the NVH performance of automobile.
Further, the lining that two free ends of described top link body are installed is coaxial, so not only can guarantee the smooth installation of bolt, has optimized simultaneously the motion characteristics of whole suspension system.
Automobile double yoke suspension top link assembly structure advantages of simple of the present invention, light, easy for installation, the low cost of manufacture of quality are fit to be applied to low and middle-grade automobiles very much.

The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
Shown in Fig. 1～5, the automobile double yoke suspension top link assembly of present embodiment comprises the top link body 2 that ball end assembly 1 is installed, two free ends of top link body 2 adopt respectively the interference mode to be pressed with front lining 5, back bush 3, and utilizing an overbolt 4 to connect, front lining 5, back bush 3 are coaxial.
Shown in Fig. 1～8, top link body 2 adopts the moulding of individual layer steel plate punched, and the cross-sectional plane of top link body 2 is the flute profile that Open Side Down, and the opening of this flute profile is reduced to the free end at two ends gradually by ball end assembly 1 place.Wherein, the cross sectional shape of the top link body 2 at ball end assembly 1 place is flute profile, and a side of bottom land has an additional groove 6, and this additional groove 6 can further be strengthened the bearing capacity at ball end assembly place; The cross sectional shape of the top link body 2 between ball end assembly 1 place and front lining 5, back bush 3 places is flute profile, and the top of the both sides cell wall of this flute profile tilts to flute profile central authorities, with improve this place's fore-and-aft direction and left and right sides to intensity and rigidity; The cross sectional shape of the top link body 2 at front lining 5, back bush 3 places is circular, and this circle has a very little breach, and therefore stressed maximum herein is designed to each and can satisfies its force request to the strongest circle of bending resistance.
