Abstract
The invention discloses a kingpin caster angle adjusting device. The kingpin caster angle adjusting device comprises a swing arm, wherein the end surfaces of the two ends of the swing arm are fixedly provided with swing arm revolving shafts which are symmetrically arranged, the swing arm revolving shafts are provided with support assemblies, combined type gaskets are arranged among the support assemblies and the swing arm revolving shafts and arranged in a group manner, the gaskets are of a multi-layer structure, the layers and the layers are dissociated so as to realize the change of the thicknesses of the combined type gaskets, and the relative positions among the support assemblies and the swing arm revolving shafts are changed. The kingpin caster angle adjusting device provided by the invention can perfectly combine steering sensitivity, portability and handling stability, and the handling property and the safe property are improved.
Description
Technical field
The present invention relates to the independent suspension field, relate 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.
Summary of the invention
Technical matters solved by the invention 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.
Technical matters solved by the invention 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 plug-in mounting realizing the variation of compound type pad thickness of two sides, and then the relative position that props up between seat assembly and the swing arm rotating shaft is changed.
In the present invention, between a seat assembly and swing arm rotating shaft, be provided with for the rubber bush that cushions.
Concrete principle of the present invention 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 present invention uses 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.

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
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 invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
