Description
Technical field
The present invention relates to a kind of bearing arrangement as described in the preamble according to claim 1, it is for particularly as the composite braces axle of the vehicle of the back axle of self-propelled vehicle, and a kind of composite braces axle as described in the preamble according to claim 4, it comprises the such bearing arrangement for it being connected with structure and/or the subframe of vehicle.In addition, the present invention relates to a kind of vehicle being equipped with such composite braces axle with the feature of claim 5.
Background technology
Composite braces reel structure becomes the parts of the wheel suspension assembly of vehicle, usually used as back axle.Its vibrational power flow has two portait rockerarms, and two portait rockerarms are rotatably provided with the wheel of axletree respectively.Portait rockerarm is interconnected to bending resistance substantially by the torsion section bar extended transverse to vehicle longitudinal direction.Wherein, reverse section bar and be constructed as follows, namely it self can reverse in the compression of one of portait rockerarm with when upholding.Therefore achieve the simple design structure of axletree, in this axletree, reverse section bar can be used as stabilizing device simultaneously.
In order to make composite braces axle connect movingly with vehicle structure, use has gone up in bearing arrangement group that is suitable, such as hub form.These bearing arrangements are usually designed to rubber-metal bearing, although also can adopt other structural form.In order to realize connecting of composite braces axle and vehicle structure, be usually provided with two such bearing arrangements.They be spaced apart from each other and in usually laying respectively between portait rockerarm and vehicle structure layout, they form a structural rotation axis, and portait rockerarm and therefore whole composite braces axle can rotate around this rotation axis.Finally, the desired performance of the part of the realization like this on chassis and shock absorber and chassis spring matching coordinative.
The well-known characteristic of composite braces axle when curve driving is the inclination of its trend oversteer.This point substantially can owing to the property of can be movable relatively of composite braces axle relative vehicle structure.Wherein, its movement is substantially based on the resilient flexibility of bearing arrangement.Its structure arranges medial branch fixed bearing element and lateral branch fixed bearing element usually, and these supporting members are respectively with composite braces axle or be connected with vehicle structure.At this, it is particularly arranged on the elastic support body between two supporting members, and this supporting mass makes the limited movement of medial branch fixed bearing element opposite exterior lateral sides supporting member become possibility.Supporting mass is usually made up of elastic body or comprises such elastic body.Wherein, the existence of such elastic part in the bearing arrangement of monomer meets expectation completely, because its decoupling effect reduces noise transmission and totally improves comfort level.
First but not merely concentrate on the textural of bearing arrangement itself in order to tackle the well-known oversteer trend of composite braces axle, had diversified structure possibility to be well-known in the prior art, but these structure possibilities.
Like this by the known a kind of composite braces axle of DE 10 2,006 033 755 A1, this composite braces axle attempts the oversteer behavior by using additional parts to avoid common composite braces axle.Propose: the portait rockerarm by reversing the interconnective carrying wheel of section bar is connected with work done connecting rod for this reason.The work done connecting rod extended between two portait rockerarms causes portait rockerarm in curve driving both by reversing section bar also by this work done link supporting.Decrease in this way portait rockerarm inwardly and to inner rotary and thus whole composite braces axle around the restricted rotational movement of vertical pivot, thus decrease the inclination tending to oversteer.
On the other hand, DE 10 2,009 043 552 A1 for be the structure of bearing arrangement in composite braces axle.This document is pointed out: the selection of supporting mass and particularly its each material behavior comprises the conflict relating to himself pliable and tough or hard structure aspect.Design that is comfortable like this, vibration damping needs to use pliable and tough material, but this material restriction riding stability.On the other hand, riding stability can be improved by using harder material, and this again the sense of hearing with the driving comfort of machinery on pay a price.In order to eliminate this goal conflict or at least make this goal conflict minimize, the substantially spherical structure of medial branch fixed bearing element is proposed.Therefore improve effectiveness in vibration suppression and the universal-joint (Kardanik) of bearing arrangement, can also service life be improved in this way except high flexibility and good universal-joint performance (Kardanizitaet).
Also should be able to realize the improvement to bearing arrangement in the following way according to CN 101 607 572 A, namely medial branch fixed bearing element and lateral branch fixed bearing element all have be positioned on respective identical side, around flange.In two supporting members are interweaved the state that arranges, their flange is spaced apart from each other by gap.Wherein, till the supporting mass be arranged between medial branch fixed bearing element and lateral branch fixed bearing element can be set between two flanges always.When the load of bearing arrangement is axial along it on the flange of medial branch fixed bearing element by its flange bearing side bearing element outside.Therefore bearing arrangement is achieved particularly along the high rigidity of its axis.
GB 1 259 802 A illustrates a kind of elastic component, and this elastic component is by power supply or the elastic behavior changing it when there being magnetic field.The elastic component within it illustrated utilizes the characteristic of electric viscosity or magnetic viscosity fluid, and these fluids solidify to a certain extent when having magnetic field or electric current and therefore improve its shearing resistance.The so possible activation of this fluid relate to a reversible process, thus makes desired shearing resistance depend on the height of each selection of magnetic field or intensity of current.
Then by US 5,609,353 A are known a kind of bearing arrangement variable in its rigidity, it is used in self-propelled vehicle when using the fluid of magnetorheological (magnetorheologisch) that can activate.
DE 10 2,007 040 600 B4 also illustrates controollable fluid bearing, and this fluid bearing is substantially for the vibration damping in certain frequency range.These fluid bearings of bearing as liquid-springing such as can be used as the chassis bearing in self-propelled vehicle.In order to minimum by causing the transmission of vibration of noise to be reduced to, propose in such fluid bearing, abandon normally used uniform, relevant to the activation of magnetorheological fluid magnetic field.
EP 0 784 163 B1 proposes a kind of bearing arrangement equally, but this bearing arrangement comprises magnetorheological supporting mass to change its rigidity.Supporting mass has advantage with magnetorheological fluid-phase ratio, and namely this supporting mass has intrinsic rigidity in unactivated state, and then this rigidity can reversibly change in the magnetic field that need produce.In addition, reduce or completely eliminate otherwise the sealing expense required when magnetorheological fluid.
In prior art, well-known bearing arrangement has made the dynamic conditioning of the continuous operation at each vehicle become possibility.Therefore its rigidity can change explicitly with desired motoring condition.Wherein, the activation of magnetorheological fluid or magnetorheological supporting mass causes particularly medial branch fixed bearing element opposite exterior lateral sides supporting member radially to be strained in the location at its usual center.Result can control the elastomeric movement that two supporting members are mutual explicitly with the intensity of the selection of magnetic field or intensity of current.
In this way, such as, when curve driving flexibly, fiercer tuning (Abstimmung) can be selected as follows, i.e. the magnetic field that is applied in by it of the rigidity of bearing arrangement or correspondingly improved for electro activation.On the other hand, if such as in order to provide a kind of vibration damping with comfortable driving mode under mainly slight curve driving, can by reducing until disconnect magnetic field or electric current reduces its rigidity again.
But still show: affected like this bearing arrangement can not the well-known oversteer trend of complete equilibrium composite braces axle.In addition, the enhancing transmission of the rigidity allowable vibration of the raising of bearing arrangement, this point particularly has an impact to sending noise except driving comfort.
In the face of well-known advantage, in its rigidity, therefore the affected bearing arrangement of energy still also has the space of improvement in any case in addition like this.
Summary of the invention
The object of the invention is in this context, as follows further exploitation a kind of for composite braces axle, the vehicle of the bearing arrangement with magnetorheological materials and a kind of such composite braces axle and a kind of corresponding outfit, namely the transformable characteristic of bearing arrangement realizes better balancing the oversteer trend of composite braces axle.
According to the present invention, the concrete part of this object by have the feature of claim 1, the bearing arrangement for composite braces axle and the composite braces axle by such, that there is claim 4 feature and corresponding outfit, the vehicle of the feature with claim 5 is achieved.Other structure useful especially of the open the present invention of each dependent claims.
It is to be noted: the feature elaborated separately in explanation hereafter and method can mutually combine with arbitrarily, in technical elements reasonable manner and show further structure of the present invention.Specification sheets further describes and describes the present invention in detail, particularly combines with accompanying drawing.
Hereafter the bearing arrangement for composite braces axle is illustrated according to the present invention.Wherein, composite braces axle arranges and is used for vehicle, and in this vehicle, it is in particular as back axle.Above-mentioned bearing arrangement is a transom be made up of a few part, can be connected movingly by this transom composite braces axle with the structure of corresponding vehicle and/or subframe.
Bearing arrangement had both comprised lateral branch fixed bearing element also bag medial branch fixed bearing element for this reason.Supporting member is configured for being connected with composite braces axle on the one hand and the structure of another aspect and vehicle and/or subframe are connected.Wherein specify: medial branch fixed bearing element or lateral branch fixed bearing element are connected with composite braces axle, and on the structure that other supporting member can be fixed on vehicle and/or subframe.
In order to realize at least limited movement of composite braces axle relative vehicle, be similar to rotatably, bearing arrangement is constructed as follows, and namely its supporting member is coupled to each other movingly.Medial branch fixed bearing element is arranged in lateral branch fixed bearing element at least partly for this reason.In order to realize connection that is lasting as far as possible and particularly vibration damping, two mutual resilient connection of supporting member.Wherein, between the first supporting member and the second supporting member, be provided with magnetorheological supporting mass, its rigidity can change when applying magnetic field.
Surrounded annularly by medial branch fixed bearing element at this supporting mass, wherein, medial branch fixed bearing element is such as arranged on the center in lateral branch fixed bearing element, and supporting mass circumferentially extends around above-mentioned medial branch fixed bearing element as the collar closed.Even supporting mass here only can with medial branch fixed bearing element and/or lateral branch fixed bearing element localized contact, preferred supporting mass is by being placed on the complete surface of these supporting members.Can absorb all sidedly in this way and continue to be delivered in the power needing between medial branch fixed bearing element and lateral branch fixed bearing element to be transmitted by supporting mass, this can not only make full use of intrinsic rigidity better, and can also make full use of better by activating the rigidity improved.
According to the present invention, support structure is as follows, and namely this supporting mass is divided into the first support region and the second support region.Wherein, the support region of supporting mass has the shape of ring segment.Therefore the supporting mass of ring-type is divided at least two ring segments, and these ring segments form the supporting mass surrounding medial branch fixed bearing element jointly.Although supporting mass can be divided into plural support region and therefore ring segment, preferably this supporting mass has only two support regions.Wherein, supporting mass can by two construct all-in-one-piece respectively, ring segment that form is support region combines.Supporting mass also can be configured to one generally, make support region and particularly ring segment only define boundary to each other, surmount the activation that these boundaries are not implemented each support region.So the one that ring segment and therefore support region such as also can become material identical with support structure, and can realize them separated from each other can activity.
Specify explicitly with the division of supporting mass of the present invention: the respective rigidity of the first support region and the second support region can change independently of one another.Wherein, the above-mentioned division of supporting mass does not require the tangible separation to this supporting mass, although this separation is admissible within the scope of the invention.This separation of supporting mass is still interpreted as the change separately from each other of supporting mass in the respective rigidity of its support region more precisely.In other words, be preferably configured to can the support region of separate activation at least two of supporting mass subregions between medial branch fixed bearing element and lateral branch fixed bearing element accordingly.Can activating and mean in meaning of the present invention: can control in its rigidity each several part region when applying magnetic field.
Wherein, be arranged on as follows by support region between the lateral branch fixed bearing element of bearing arrangement and medial branch fixed bearing element, namely medial branch fixed bearing element and/or lateral branch fixed bearing element can be bearing on the first support region along opposite directions or be bearing on the second support region.In this way, support region is relatively arranged, and make medial branch fixed bearing element such as press to the first support region when the load of the travel direction of sensing vehicle, and the second support region is removed load.On the other hand, if medial branch fixed bearing element is pointed in load trailing moverment direction in this example, the first support region is gone load and the second support region by application of load.
Therefore, achieve the activation of the support region to difference application of load in an ideal way, support region corresponding thereto then keeps non-activity in its intrinsic rigidity.Only activate the support region that in fact that should overcome the possible motion of composite braces axle so in a beneficial manner respectively.On the other hand, respectively the support region of non-activity keeps its more pliable and tougher characteristic, to maintain the advantage of vibration damping at least in the subregion of supporting mass and stress release treatment.
By therefore can different adjustment, support region respect to one another in their respective rigidity, can reach in addition: the reason due to unactivated support region achieves its compression targetedly.Produce other advantage thus according to structure, these advantages are particularly owing to the structure of composite braces axle relative vehicle and/or the obliquity that can so control of subframe.
The special advantage of the structure of supporting mass of the present invention is: the possible change of its rigidity no longer forcibly comprises its whole object now, but such as only comprises subregion as required, one of support region being similar to it.Therefore now it is likely that supporting mass is only activated local by applying magnetic field, and other region keeps their unactivated intrinsic rigidity (non-activity).Particularly can the achieving bearing arrangement and can adapt to each load condition targetedly by activity of separation of each support region of supporting mass.
Therefore one of supporting mass such as during curve driving the support region of application of load can be improved in its rigidity targetedly by activating, and not have or the support region of only faint application of load keeps non-activity in its intrinsic rigidity.The compression of support region can be overcome by being activated when needed in this way, and on the other hand non-activity still continue to maintain the effect of its vibration damping and therefore stress release treatment with therefore more pliable and tougher support region.
Particularly by activating the support region of on-load pressure respectively targetedly, the motion of reason overcome the relative vehicle of composite braces axle in bearing arrangement, that form oversteer.This is the result produced by the rigidity improved as required of the support region be activated, support region no longer elastic deformation or at least now only owing to acting on the reason of the load on it and limited elastic deformation now.
Pressure load on the support region of the supporting mass addressed here is particularly based on curve driving.In this possible side force by being arranged on tire on composite braces axle and wheel is delivered on medial branch fixed bearing element or lateral branch fixed bearing element, the supporting member elastic movement that and then supporting member of application of load is relatively other like this.In order to the obliquity of the structure and/or subframe that at least limitedly overcome composite braces axle relative vehicle, need such motion is reduced to minimum or stops completely.
Owing to can activate now each support region of supporting mass dividually, balance that the variable like this characteristic of bearing arrangement makes the improvement of the oversteer trend to composite braces axle, that can apply targetedly there and control becomes possibility.
Such as can change independently of one another in the rigidity of support region as follows, namely arrange two that be separated from each other, for generation of the device in magnetic field.Device like this for generation of magnetic field can act on a support region respectively.Targetedly desired magnetic field is applied on each support region in this way, only to activate this support region and therefore to change this support region in its rigidity.
Certain support region also can have material behavior different from each other, makes these support regions have intrinsic rigidity such as different from each other.So such as loading the higher support region of load in curve driving in a typical manner can construct rigidity is stronger from the beginning.
Therefore can consider within the scope of the invention: the first support region and the second support region are when having identical rigidity without magnetic field or without when respective magnetic field.Also can consider: support region is when having identical volume without magnetic field or without when respective magnetic field.Achieve simple installation in this way, because bearing arrangement need not be arranged with joining with directional correlation.Therefore processing also generally, efficiency is higher, and this particularly gives the credit to identical material and/or shape.
According to particularly preferred structure, the first support region and/or the second support region can by apply magnetic field or respective changes of magnetic field they/its volume.In other words, the present invention specifies: the volume of each support region can by increasing its activation targetedly.
In this way composite braces axle directed in provide the control be highly profitable.The support region expanded preferably by its activation like this with its opposed support region non-activity while be activated.So medial branch fixed bearing element can press to the support region of non-activity due to the expansion of a support region, this causes moving targetedly of its opposite exterior lateral sides supporting member.So composite braces axle can according to the degree ground like this tilt adjustments consciously of the load in curve driving, i.e. its oversteer trend of its complete equilibrium or completely understeer.
Utilize this handle produce for composite braces axle ACTIVE CONTROL, at continuous operation with minimum material consumption, brand-new possibility.Eliminate the well-known shortcoming of composite braces axle so to a certain extent, wherein composite braces axle can run as active chassis parts now.Due to bearing arrangement for its rigidity and the control therefore suited the requirements to inner side and lateral branch fixed bearing element position each other, now can well-known oversteer trend in complete equilibrium composite braces axle.In addition, the possibility for only partly improving the rigidity of bearing arrangement allows to reduce transmission of vibration significantly compared with the situation in its in the prior art completely radial structure strained.The present invention of such introduction not only to driving comfort, but also produces favorable influence to sending noise.
In addition, the present invention is directed to a kind of composite braces axle, this composite braces axle particularly comprises at least one foregoing bearing arrangement.
Particularly preferably composite braces axle of the present invention can with in vehicle, the f-w-d combination particularly in self-propelled vehicle.
Composite braces axle of the present invention can comprise two portait rockerarms be spaced apart from each other usually, and these portait rockerarms are used to connect wheel respectively.In the assembled state of composite braces axle, portait rockerarm is arranged essentially parallel to longitudinal direction or the travel direction extension of corresponding vehicle.In addition, above-mentioned portait rockerarm is interconnected by the torsion section bar extended between these portait rockerarms.Two portait rockerarms are preferably designed for rigidity by the connection of reversing section bar.Reverse section bar at this and can be used as stabilizing device, wherein, the resistance that it can overcome by structural limitations reverses voluntarily.Except as except the structure of hollow profile, particularly U-shaped or the cross-sectional plane of T-shaped be suitable for reversing section bar.
In order to the structure or subframe that make composite braces axle and vehicle are connected, be provided with two foregoing bearing arrangements in a beneficial manner.The structure example of vehicle is as being the vehicle frame of carrying or the region of subframe or the relative configurations from self-supporting body.
Bearing arrangement can spaced setting of turning up the soil in a beneficial manner, and wherein, the bearing arrangement of monomer is connected with each in portait rockerarm.Arrange bearing device at this and form swivel bearing respectively, each portait rockerarm can be connected with the structure of vehicle and/or subframe rotationally around the rotation axis of this swivel bearing.Wherein, the rotation axis of two bearing arrangements is usual but extend on common axis optionally, makes these bearing arrangements mutually to center.
Supporting mass due to each bearing arrangement is divided into the first support region and the second support region, and composite braces axle of the present invention can guide now ground targetedly or limit structure and/or the subframe motion of ground relative vehicle completely.So the present invention also provides a kind of half initiatively (semi-aktiv) composite braces axle of bearing arrangement with having a magnetorheological part, to balance the typical oversteer trend of well-known composite braces axle.
