Abstract
The invention relates to an adjusting device of a kingpin caster angle of a double wish-bone arm type front suspension system, which comprises at least one adjusting inserting piece (3) which is inserted and fixed between attaching surfaces wherein an upper swinging arm shaft is connected a fixed bracket (5) of a frame. Connecting points comprises front connecting points and rear connecting pints; when the inserting piece (3) is inserted into the front connecting points, the kingpin caster angle is reduced, and when the inserting piece (3) is inserted into the rear connecting points, the kingpin caster angle is increased. By setting the inserting piece, the kingpin caster angle is adjusted within the design requirements, thereby the errors of processing technique is made up, and vehicles retain the capability of linear running or quick restoration of a steering wheel after steering in the process of running.
Description
Technical field
Invention relates to a kind of setting device and control method of kingpin caster angle of double wish-bone arm type front suspension.
Background technology
In non-freestanding steel spring front suspension system, the knuckle pin angle of propons generally can not be regulated, mainly realize the variation of kingpin caster angle during the car load design by the relative position that changes leaf spring holder and stub, kingpin caster angle is a determined value after the propons entrucking, its levels of precision has only by processing technology and guarantees, if real vehicle kingpin caster angle and design value error are bigger, some vehicle can adopt increase wedge cushion block to change casterangle between steel spring and bridgework.
Manned vehicle field, front suspension are independent suspension substantially, and stub is a virtual axis, but still are main positional parameters of front-wheel, will cause running out the way more greatly with the design value error or return plus effect relatively poor.Because of the stub of this suspension is a virtual axis, regulate comparatively difficulty.So particularly all do not have the control apparatus of kingpin caster angle on the vehicle of MacPherson strut in most of vehicle, the angle of stub mainly guarantees by the working accuracy of parts.
Summary of the invention
The present invention is for having control apparatus and the method for adjustment that double wish-bone arm type front suspension system provides a kind of simple in structure, easy to operate kingpin caster angle.
The control apparatus of the kingpin caster angle of double wish-bone arm type front suspension system of the present invention comprises that at least one adjusts inserted sheet, and it is inserted and secured on the top link axle or down between arm shaft and the binding face that fixed support on the vehicle frame connects.
Wherein, point of attachment and back point of attachment before top link axle and described support bracket fastened point of attachment comprise, when preceding point of attachment inserted the adjustment inserted sheet, kingpin caster angle reduced, and when inserted sheet was adjusted in back point of attachment insertion, kingpin caster angle increased.
Preceding point of attachment or point of attachment place, back have bolt, looser a bolt the adjustment inserted sheet is inserted, and bolt are tightened with the fixing inserted sheet of adjusting again.
At least one adjustment inserted sheet is made by the material such as the 65Mn of high strength, high hardness and high-wearing feature, and its thickness is identical or different, can be at least a or multiple of 1mm, 1.5mm and three kinds of thickness of 2mm.
The control method of the kingpin caster angle of double wish-bone arm type front suspension system of the present invention may further comprise the steps: detect kingpin caster angle whether in the design value scope; When kingpin caster angle is not in the design value scope, need the thickness and the quantity of the adjustment inserted sheet of employing according to the deviation selection of detected kingpin caster angle; At least one that need are adopted adjusts that inserted sheet is inserted and secured on the top link axle or down between arm shaft and the binding face that fixed support on the vehicle frame connects.
Technique effect of the present invention is when going up the four-wheel position finder detection after car load rolls off the production line, if detect kingpin caster angle not in the design value scope, can adjust inserted sheet in this device by regulating, and the kingpin caster angle of front-wheel is reached within the scope of designing requirement.Thereby can remedy errors of processing technique, make the ability of vehicle maintenance straight-line travelling in the middle of travelling or turn to the back steering handwheel to return positive ability rapidly.
Description of drawings
Fig. 1 is the main parts size and the fit scheme drawing of setting device.
Fig. 2 is for adjusting the inserted sheet constructional drawing.
The specific embodiment
In the double wish-bone arm type front suspension system, virtual stub is the line at pumping arm action ball pin center, as long as change top link or following swing arm ball pin center X can realize the change of kingpin caster angle to coordinate.
The control apparatus of the kingpin caster angle of double wish-bone arm type front suspension system of the present invention and fit are as shown in Figure 1, the principle of adjusting is that the X at the center of swing arm ball pin under keeping is constant to coordinate, and the X of change top link ball pin 1 realizes the change of kingpin caster angle to coordinate.Concrete scheme is that the adjustment inserted sheet 3 of increase different-thickness specification between top link axle 1 and binding face that fixed support 5 on the vehicle frame connects is achieved, two places that the front and back distribution is arranged because of point of attachment, when preceding point of attachment increases inserted sheet, kingpin caster angle will reduce, otherwise, when the back point of attachment increases inserted sheet, kingpin caster angle will increase.
The control method of the kingpin caster angle of double wish-bone arm type front suspension system may further comprise the steps: detect kingpin caster angle whether in the design value scope; When kingpin caster angle is not in the design value scope, need the thickness and the quantity of the adjustment inserted sheet of employing according to the deviation selection of detected kingpin caster angle; At least one that need are adopted adjusts that inserted sheet is inserted and secured on the top link axle or down between arm shaft and the binding face that fixed support on the vehicle frame connects.
Only bolt 4 preceding or the back point of attachment need be unscrewed several teeth during concrete the adjusting and be about to the inserted sheet insertion.The inserted sheet shape as shown in Figure 2, handgrip part 6 is left with handled easily in its top, will insert mouthfuls 7 when inserting inserted sheet and aim at bottom bolts 4 are depressed into, and attachment bolt 4 as prescribed moments is tightened again, thereby finishes the operating process of whole adjusting.Because of there are frequent high-intensity oscillation in top link axle 1 and vehicle frame before, so to the requirement of inserted sheet material be: high strength, high hardness and wear resisting property are good, as are 65Mn.
In the control apparatus of the present invention, the thick inserted sheet of front or rear point of attachment every increase 1mm, knuckle pin angle can reduce or increase by 0.4 degree.Inserted sheet is designed to 1mm, 1.5mm and three kinds of thickness specifications of 2mm, so car load can be judged inserted sheet thickness and the quantity that needs employing after the deviation that detects kingpin caster angle on the four-wheel position finder, puts in place thereby can once regulate.
