Abstract
A kingpin caster angle adjusting device comprises a swing arm, wherein swing arm rotating shafts are fixedly arranged on the end faces of two ends of the swing arm, the swing arm rotating shafts are symmetrically arranged, support assemblies are arranged on the swing arm rotating shafts, combined type gaskets distributed in set are arranged among the support assemblies and the swing arm rotating shafts, the combined type gaskets are of multi-layer structures, and separation in a pulling mode can be achieved among layers of the combined type gaskets to achieve thickness change of the combined type gaskets, and thus relative positions of the support assemblies and the swing arm rotating shafts are changed. The kingpin caster angle adjusting device perfectly combines flexibility of steering, convenience and handling stability, and improves handling performance and safety performance.
Description
Technical field
The utility model relates to the independent suspension field, relates in particular to a kind of kingpin caster angle regulating mechanism of double cross arm independent suspension.
Background technology
For the design and entrucking of independent suspension, how wheel alignment parameter is controlled at zone of reasonableness, meet the requirement of car load road-holding property is an important topic always.And generally speaking wheel alignment parameter refers to kingpin caster angle, Kingpin inclination angle, outward camber and toe-in, and wherein kingpin caster angle has very significant effects to ease of steering and the returnability of vehicle handling stability.
Present existing double cross arm independent suspension can't be adjusted kingpin caster angle, when vehicle and load-carrying variation, can't satisfy the requirement that tandem product changes kingpin caster angle, stub can not be adjusted the kind that had both increased product component, has increased product development and production cost again.
The utility model content
The technical matters that the utility model solves is to provide a kind of kingpin caster angle control apparatus, this kingpin caster angle control apparatus can be used for the double cross arm independent suspension structure, can carry out kingpin caster angle at the suspension of this structure and regulate, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The kingpin caster angle control apparatus, comprise swing arm, on its swing arm two ends end face the swing arm rotating shaft is arranged fixedly, described swing arm rotating shaft is that symmetry is installed, it is provided with a seat assembly, and is provided with the compound type pad of arranging in groups between a seat assembly and swing arm rotating shaft, and this pad is multiple-structure, and can detach between layer and the layer and the variation of plug-in mounting with realization space, compound type pad both sides, and then the relative position between a seat assembly and the swing arm rotating shaft is changed.
In the utility model, between a seat assembly and swing arm rotating shaft, be provided with the rubber bush for buffering.
Concrete principle of the present utility model can be expressed as: pad is adjusted kingpin caster angle mechanism in groups, comprises the rubber bush assembly, and a seat assembly, pad and upper and lower transverse arm are formed in groups.Guaranteeing under the constant situation of wheelbase, by changing the pumping arm action combination of pad in groups, changed the x coordinate of point in the car load system of axes in the upper and lower swing arm, thereby also changed the outer point coordinate of pumping arm action, namely reached and adjusted the purpose of kingpin caster angle, thereby satisfied different automobile types to ease of steering, steering gyrus positive force performance demands.
Beneficial effect: the utility model is used many-body dynamics simulation theory, optimization method, suspension system is carried out the simulation calculation analysis, determine the upper and lower swing arm place single-sheet thickness of pad in groups according to Calculation results, simultaneously, because the array mode of pad can have multiple in groups, can satisfy suspension to the requirement of different casterangles, so both reduced the kind of product component, product development and productive costs have been reduced again, improve ease of steering, the steering reversal performance of automobile simultaneously, improved maneuvering performance and safety performance.

Marginal data: 1-swing arm rotating shaft, 2-rubber bush assembly, 3-arm swing support assembly, the 4-swing arm, 5-is pad in groups, swing arm under the 6-.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the kingpin caster angle control apparatus of Fig. 1 ~ Fig. 2, because its installation position of pad in groups in upper and lower swing arm is equipped with two kinds of forms.Pad 5 is installed on the swing arm 4 side faces at both ends positions of swing arm rotating shaft 1 in groups in embodiment one, and in embodiment two, pad 5 is installed in arm swing support 3 outer ends in groups.In the structure of Fig. 1 and Fig. 2 kingpin caster angle mechanism mainly the array mode of pad 5 makes swing arm rotating shaft 1 move axially along its rotation axis by adjusting in groups, adjust interior some O1 of upper and lower swing arm 4 and O2 at the coordinate of vehicle axis system X-axis, changed the coordinate of the bulb center-point of upper and lower swing arm 4, i.e. the kingpin caster angle of swing arm rotating shaft 1 changes.
During adjusting, guaranteeing under the constant situation of wheelbase, several pads that only need take off on the pad in groups 5 of correspondence one side of upper and lower swing arm 4 are put into opposite side, can change the position of putting in the upper and lower swing arm 4 in vehicle axis system x direction, thereby change the casterangle of swing arm rotating shaft 1 stub, make suspension system meet the car load operating needs.
Owing to adopt the kingpin caster angle control apparatus of Fig. 1, Fig. 2, its central axis changes can be expressed as Fig. 3 and Fig. 4 respectively, and can release then: the initial casterangle design value of suspension is α
0, selected Top Crossbeam every thickness of pad in groups is a, and lower cross arm every thickness of pad in groups is b, and respectively there is N pad upper and lower transverse arm both sides.Pad taking-up of Top Crossbeam B side is installed to the A side, pad of lower cross arm A side is taken out be installed to the B side accordingly, then the kingpin caster angle increase is α
1If opposite sense is regulated pad, then kingpin caster angle is reduced to α
11And the like, m pad taking-up of Top Crossbeam B side is installed to the A side, m pad of lower cross arm A side taken out be installed to the B side accordingly, then the kingpin caster angle increase is α
mIf opposite sense is regulated pad, then kingpin caster angle is reduced to α
Mm
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
