Description
Technical field
The invention belongs to automobile running system technology, be specifically related to a kind of McPherson automobile front suspension structure.
Background technology
Suspension is the force transmission connections between vehicle frame (or self-supporting body) and vehicle bridge (or wheel), its function road surface is acted on the moment that the vertical reaction (bearing force) on wheel, longitudinal counter-force (tractive force and braking force) and lateral reaction and these counter-forces cause all will be delivered on vehicle frame (or self-supporting body), to ensure the normal traveling of automobile.Suspension is as one of automobile chief component, and affecting the performances such as automobile ride, handling stability, crossing ability, is the key areas of automobile design, research.
The form of automotive suspension is divided into dependent suspension and independent suspension two kinds.
The wheel of dependent suspension is contained in the two ends of an overall axletree, when one side wheel bounce, affect opposite side wheel also to beat accordingly, make whole body vibrations or inclination, stationarity and the traveling comfort of automobile are poor, but because structure is comparatively simple, bearing capacity is large, still has the rear suspension of part car to adopt this pattern at present.
The axletree of independent suspension is divided into two sections, and every wheel coil spring is arranged on below vehicle frame (or vehicle body) independently, and when a sidecar wheel is beated, another side wheel is not involved, the stationarity of automobile and traveling comfort good.Modern Car fore suspension and rear suspension mostly have employed independent suspension, and has become a kind of development tendency.But this suspension structure is more complicated, and bearing capacity is little.
Independent suspension is different by version, can be divided into again wish-bone arm type, trailing arm type, multi link formula, candle formula and MacPherson type etc.
MacPherson strut is one of classical car suspension of american car engineer Mai Fuxun design, it comprises coil spring, telescopic shock absorber, lower swing arm and steering swivel, keystone configuration is simple is exactly that coil spring is sleeved on telescopic shock absorber and forms front standing pillar, the lower end of steering swivel is hinged by the termination, outside of ball end and lower swing arm, and the upper end of steering swivel is fixedly connected with the lower end of telescopic shock absorber by shock absorber support.To the phenomenon of front, rear, left and right skew when telescopic shock absorber can avoid coil spring stressed, restriction coil spring can only do the vibration of above-below direction, and by the stroke length of telescopic shock absorber and degree of tightness, can set soft or hard and the performance of suspension.McPherson strut is arranged because its structure is simple, maintainability is good, be conducive to car load space, and domestic market A, B level car front suspension frame great majority all adopt this kind of suspension frame structure.
But, compare with other forms of suspension frame structure, traditional McPherson strut structure also also exists shortcomings, wherein comprises following major defect: the toe-in value that traditional McPherson strut structure can only regulate four-wheel aligner middle by steering track rod, cannot adjust Kingpin inclination angle.
Summary of the invention
The object of the present invention is to provide a kind of McPherson automobile front suspension structure, realize the adjustable function of Kingpin inclination angle, so that steady adjustment grasped by car load.
McPherson automobile front suspension structure of the present invention comprises coil spring, telescopic shock absorber, lower swing arm, steering swivel and shock absorber support, and described coil spring is sleeved on telescopic shock absorber; Lower bulb hinged is passed through on the termination, outside of lower swing arm in the lower end of described steering swivel; This front suspension structure also comprises a connection bracket, described connection bracket is inverted U-shaped support, two pin of the lower end of described U-shaped support are that sit-astride is arranged and is hinged on lower swing arm, the horizontal support plate being provided with in the upper end of U-shaped support the perpendicular support plate protruded upward and stretching out outside vehicle body, the upper end of described steering swivel is connected to the end of described horizontal support plate by upper bulb, described telescopic shock absorber lower end is fixed on the perpendicular support plate of U-shaped support by shock absorber support; It is characterized in that: the horizontal support plate end of described U-shaped support is eccentric nut for connecting the nut assembled in the hole of upper bulb, described upper bulb is connected on described horizontal support plate with coordinating of eccentric nut by its ball end.
Further, two pin of described U-shaped support have relative pin-and-hole, arm body between the middle part of described lower swing arm and termination, outside has the through hole of corresponding matching, U-shaped support is hinged on lower swing arm through the pin-and-hole on U-shaped support two pin and the through hole on lower swing arm by a connecting pin.
Further, described shock absorber support has the c-shaped tubular suit portion of cross-sectional plane, and the lower end of bumper is enclosed within the tubular suit portion of shock absorber support; Two vertical edges in the tubular suit portion of shock absorber support extend two pieces of flat boards, the perpendicular support plate of described U-shaped pedestal upper end is installed between two pieces of flat boards, corresponding bolt hole is all had with on perpendicular support plate at two pieces of flat boards, by bolt, two flat boards are fixed together with perpendicular support plate, and bumper lower end and shock absorber support are locked.
The present invention has the following advantages: the horizontal support plate of U-shaped support is connected by eccentric nut with between upper bulb, by adjusting the eccentric orfice position of eccentric nut, the relative position that can realize between bulb and U-shaped support regulates, and then the relative position realized between steering swivel and U-shaped support regulates, thus indirectly achieve the effect of adjustment Kingpin inclination angle, be conducive to the adjustment of four wheel locating parameter, and then be conducive to realizing car load and grasp steady adjustment.
