Description
Technical field
The present invention relates to automobile suspension systems, and in particular, to after a kind of linear guiding using double spherical plain bearing rod ends
Suspension system.
Background technology
Suspension is to ensure that wheel either has elasticity between vehicle bridge and automobile bearing system (vehicle frame or monocoque body)
Load is contacted and can be transmitted, impact, decaying vibration are mitigated and adjusts the automobile related dress such as vehicle body position in the process of moving
The general name set.General suspension is mainly made of elastic element, damping device and guiding mechanism three parts.In some cases, certain
One parts and plays two kinds or three kinds, for example leaf spring is simultaneous plays elastic element and guiding mechanism.Wherein lead
Be to ensure that power all between wheel and vehicle body or vehicle frame and torque reliable delivery to the function of mechanism, and determine wheel relative to
The placement property of vehicle body or vehicle frame.The variation feelings of movement locus and wheel alignment parameter when guiding mechanism determines wheel hop
The position of roll center and trim center before and after condition and automobile, largely affect vehicle control stability and
Anti- trim ability.
The characteristics of according to guiding mechanism, automotive suspension can be mainly divided into rigid axle suspension and independent suspension two major classes.It is non-
Independent suspension is coupled between being typically characterized by left and right wheels by a buckstay or non-disconnected vehicle bridge, when unilateral wheel
When bounce, other side wheel is directly influenced.The stationarity of Non-separation suspension system and comfort are poor, but have again make simultaneously
The feature that valence is low, bearing capacity is big, the rear suspension of part pony car and lorry, motor bus are equipped with this suspension system at present.Solely
The wheel for being structurally characterized in that both sides of vertical suspension couples individually through resilient suspension with vehicle body or vehicle frame, and vehicle bridge makes disconnection
Formula.Therefore, independent suspension has the advantage that：1. both sides wheel can move alone and be independent of each other, improve handling；2. reducing
Nonspring carried mass is conducive to the ride comfort of automobile；3. using broken bridge of car, engine location can be reduced, reduces vehicle weight
The heart；4. wheel movement space is larger, suspension rate can be reduced, improves ride comfort.The above advantage makes independent suspension by widely
It applies on automobile, the deflecting roller of especially car all generally uses independent suspension, in order to improve driving safety, increasingly
The rear suspension of more sedan limousines also uses independent suspension.
In terms of the difference of suspension property, guiding mechanism accounts for very big factor, and the characteristics of motion of guiding mechanism directly affects vehicle
Take turns the variation of positional parameter.Although the structure of suspension is different, final purpose is all by various designs so that front-wheel
The variation of positional parameter during the motion is reasonable and small as possible.Currently, most widely used independent suspension is main on automobile
Have：McPherson strut, double cross arm independent suspension and multi-connecting-rod separated suspension.Generally speaking, current most economical applicable, sexual valence
It is MacPherson type than highest independent front suspension；It is multi link and double wish-bone arm type that high-performance adjustment and matched suspension, which can be done,；Knot
It is multi link formula that structure is most complicated, realizes function at most.
Although conventional independent suspension can functionally meet suspension design requirement at present, work as wheel hop
When, wheel alignment parameter can change.In practical applications, the variation of any positional parameter of wheel all can be to automobile operation stabilization
Property or other aspect performances have an adverse effect, such as wheelspan variation can cause automobile straight-line travelling ability decline, simultaneously
Also cause rolling resistance increase and the influence to steering；The variation of camber angle can cause abnormal tyre to wear.Mai Fu
It is inferior that damper lower fulcrum changes therewith with sideway arm swing, the oblique angle of main pin axis when being suspended in wheel and moving up and down, because
This its wheel alignment parameter has a greater change in Suspension movement.Double fork arm type equal suspensions, can by the upper lower cross arm of rational design
So that wheel and stub Parameters variation are little；It, cannot fundamentally solution portion but due to being limited by guiding mechanism motion principle
Positional parameter is divided to change excessive problem.It is essentially all complicated space curve that multi-link lever suspension fork movement locus is resonable, which to be referred to,
So that situation of change of wheel alignment parameter during wheel moves up and down is more outstanding than traditional McPherson suspension and double transverse arms
Frame etc. is more severe；And suspension adjustment and matched difficulty are big, and movement and power performance are very sensitive to structural parameters, if
It is improper to match, and the variation range of wheel alignment parameter can be very big.
When how to ensure wheel hop, it is in independent suspension structure innovative design that positional parameter, which will not change,
A key points and difficulties.In the composition of suspension guide rod in the prior art, hinge movement pair is more, alternatively, guide rod
It is longitudinally rigid poor along wheel for elastic rod, in short, the rod end of guide rod is turning joint connection, although hinge energy
It is enough preferably to bear the load along hinge radial direction, but when bearing along the load of hinge axial direction, performance is bad, is easy to make
At the friction and abrasion between guide rod and engaging lug or gasket.After longevity of service, it be easy to cause suspension guide rod
Gap is generated between engaging lug, work is undesirable, directly affects the performance and vehicle maneuvering performance of rear-suspension system entirety.
Invention content
