Technical field
The spindle guide that the present invention relates to a kind of auto body coupling connection that is used to make back axle and automobile is to bearing.The invention still further relates to a kind of twist-beam rear axle with this spindle guide to bearing.
Background technology
The composite braces axle is current also to be coupling connection pull rod shaft under broad sense, is widely used in the car as back axle because it is simple in structure and functional characteristic good.Its example particularly can be known by DE195 07 397 A1 or DE 197 17 276 A1.
These back axles generally include: two longitudinal ties that stretch along automobile longitudinal more or less; And make the counter-bending crossbeam that but can reverse of these longitudinal tie bonded assemblys, these longitudinal ties swingably before the end section coupling be associated on the auto body.On the section of the rear end of these longitudinal ties, respectively be provided with an automotive wheel.
By means of so-called spindle guide to bearing with back axle swingably coupling be associated on the auto body, described spindle guide is to bearing rubber-and-metal bearing normally.These bearings had both affected the traveling comfort of back axle, affected the ride characteristic at desirable rotation aspect of performance of back axle again.But both are difficult to take into account.In order to make driving very comfortable, and make axle on sound, realize good decoupling zero with auto body, wish that elastic stiffness (Federsteifigkeit) is lower, and, make preferably that again elastic stiffness is higher in order to realize good driving dynamics characteristic and higher life-span.Therefore, common spindle guide generally all is the compromise of described these requirements to bearing.This spindle guide is for example known by DE 43 11 090 A1 to bearing.This spindle guide to bearing comprise the metallo-inner sleeve, with the concentric metallo-outer tube of this inner sleeve and be arranged in rubber bodies between these sleeve pipes.
Summary of the invention
At axle back and forth during springing, because relative motion can produce noise at spindle guide in bearing region.The objective of the invention is, provide ancillary method at this.
Employing according to claim 1 be used to make the spindle guide of back axle and auto body coupling connection to bearing, can realize this purpose.Spindle guide of the present invention comprises to bearing: be used for the outer tube with back axle coupling connection; Be used for being arranged in still the internals on the auto body, these internals are inserted in the outer tube; And being used between outer tube and internals is supported on outer tube the rubber bodies on the internals swingably.This spindle guide particularly is to the feature of bearing: internals have stop washer, and this stop washer is spaced apart at the axial end portion section of axial and outer tube; Rubber bodies is connected securely with stop washer.
Axle is under steam during elastic movement thus, relative motion can not occur between rubber bodies and static parts are current stop washer, thereby have prevented noise and wearing and tearing.So just saved and given the axial contact surface of rubber bodies lubricated, just required so as common rubber-and-metal bearing.
Rubber bodies is current not only can be the natural rubber body, and can be elastic body commonly used in rubber-and-metal bearing.
Content described in other claim is the favourable improvement of spindle guide to bearing.
The stop washer of the internals that body side is fixing preferably stretches out diametrically, is positioned at the opposite of the axial end portion section of outer tube until this stop washer, and spaced apart by rubber bodies with this axial end portion section.Rubber bodies thereby radially extend in the zone between stop washer and outer tube axial end portion section.So although rubber bodies is fixed on the static stop washer, axle still can be swung with respect to auto body.Consider the material behavior of employed elastomeric material, the spacing between stop washer and outer tube axial end portion section can not influence rubber bodies attached on the stop washer through suitably selecting, making.
Affact the direct part between outer tube axial end portion section and stop washer by rubber bodies of side force on the back axle, be transmitted in the stop washer, and then be transmitted in the auto body.So just can realize very directly response to side force.
In addition, can make automobile longitudinal and transversely elastic stiffness decoupling zero to a certain extent.
The preferred rubber body forms the projection of annular radially for this reason, and this protruding external diameter is greater than the internal diameter of outer tube.
The preferred rubber body is connected with stop washer all sidedly.Under the situation of compact dimensions, realize best adhering to thus.
According to another favourable design, outer tube has radially flange at it on the end section of stop washer, and rubber bodies just abuts on this flange.This can make that side force imports to the rubber bodies from outer tube swimmingly.
In addition, rubber bodies can be connected with outer tube securely, so that also can avoid noise and wearing and tearing here.
Internals have kernel, and kernel extend in the outer tube and with stop washer and is connected.According to a kind of favourable design, kernel and stop washer are jointly made integratedly.But stop washer also can be spaced apart with interior pipe in the axial direction, and tighten with automobile.
As known by DE 197 17 276 A1, the bearing rigidity of axle pull bar bearing transverse to the longitudinal axis of outer tube at least first direction and with the direction of this first direction contrary on vary in size.Preferred bearing rigidity affacts under the situation on the back axle situation greater than the power acting in opposition in power along the travel direction that advances.Also can take opposite set-up mode when needed.For example can utilize reniform depression, the unsymmetric structure of kernel, the unsymmetric structure of outer tube or the combination of these measures of different sizes on the rubber bodies, realize different rigidity.
Preferably on twist-beam rear axle, use the spindle guide of two aforementioned manner to bearing.These spindle guides all are positioned to bearing on the travel direction that advancing of two longitudinal ties that stretching on the automobile longitudinal basically and are positioned on the fwd end section, and join with the auto body coupling swingably.Oscillating axle essentially horizontally and extend substantially transversely to the travel direction that advances and stretch.
Description of drawings
By the embodiment that is shown specifically in the accompanying drawing, at length introduce the present invention below.Shown in the figure:
Fig. 1 is the schematic top plan view according to the embodiment of twist-beam rear axle of the present invention; With
Fig. 2 is the horizontal cross of spindle guide of the present invention to bearing.
The specific embodiment
Twist-beam rear axle 1 shown in Fig. 1 comprises two longitudinal ties 2 that stretch along automobile longitudinal basically, and these longitudinal ties connect by crossbeam 3.Crossbeam 3 is counter-bending according to known mode, but can reverse (torsionsweich).The wheel carrier that is used to support automobile back wheel 4 is positioned at the rear end section of each longitudinal tie 2.In addition, the front end section of each longitudinal tie 2 all joins to bearing 5 and auto body 6 couplings by spindle guide.
In the embodiment shown, spindle guide stretches transverse to the automobile longitudinal or the travel direction on even keel that advances to the oscillating axle of bearing 5.But also can be with this towards different, and make still all to have with respect to automobile longitudinal with respect to horizontal direction and be no more than about 25 ° drift angle.
In Fig. 2, at length show spindle guide to bearing 5.It comprises: be used for the outer tube 7 with back axle 1 coupling connection; Be used for being arranged in still the internals 8 on the auto body 6; And being used between outer tube 7 and internals 8 is supported on outer tube 7 rubber bodies 9 on the internals 8 swingably.
Outer tube 7 has columniform sleeve pipe section 10, forms the flange 12 of radially projection on the axial end portion section 11 of this sleeve pipe section.But sleeve pipe section 10 and flange 12 also can be made into initial divided portion, and then interconnect.But they also can make a part.Under confined state, outer tube 7 is permanently connected with longitudinal tie 2 or bearing body.This outer tube is preferably made of plastic, but also can be made of metal.
Internals 8 have kernel 13 and stop washer 14.Stop washer 14 is arranged in here on the axial end portion section for the kernel 13 of tubulose.This stop washer or be fixed on for example is welded on the kernel 13, or makes integratedly with kernel 13.
In the deformation design of this embodiment, stop washer 14 also can that is to say before being disposed axially in kernel 13, and is spaced apart with this kernel.So two parts 13,14 only connect by rubber bodies 9.In this case, stop washer 14 can specially for example be fixed on and be tightened on the auto body, is pressed on the auto body but also can pass the screw axial that kernel 13 extends with kernel 13 and rubber bodies 9.
As shown in Figure 2, the internals 8 with kernel 13 extend among the outer tube 7, and on the contrary, stop washer 14 is spaced apart with the axial end portion section 11 of outer tube 8 in the axial direction.Current, the external diameter of stop washer 14 is greater than the internal diameter of outer tube 7.In the embodiment shown, the external diameter of stop washer 14 provides the permanent seat of broad thus also greater than the external diameter of flange 12 for the rubber bodies 9 of following detailed introduction.
Rubber bodies 9 comprises that first section 15 and second section, 16, the first sections are positioned at the inside of outer tube 7, and second section axially stretches out from outer tube 7 in stop washer 14 1 sides.Second section has occupied the zone between the axial end portion section 11 of stop washer 14 and outer tube 7, and it has formed a kind of projection 17 of annular, and the external diameter of projection is greater than the internal diameter of outer tube 7.The projection 17 of annular abuts on the flange 12 of stop washer 14 and outer tube 7 in the axial direction.
For fear of between the static section of rubber bodies 9 and auto body, occurring relatively moving, make rubber bodies 9 and stop washer 14 be permanently connected for example prevulcanization (anvulkanisiert).The preferred rubber body is not fixed on the stop washer 14 with having air gap all sidedly.Internals 8 and stop washer 14 itself are arranged on the auto body still., and then cause when longitudinal tie 2 is swung with respect to auto body that spindle guide mainly is out of shape to the rubber bodies 9 of bearing 5 at back axle 1 elastic movement in the zone of second section 16.But owing to be permanently connected, wearing and tearing neither can occur, also can not produce interference noise with stop washer 14.
Rubber bodies 9 also is connected with outer tube 7 in its contact area securely, for example prevulcanization, thus when back axle 1 elastic movement, wearing and tearing equally neither can appear between rubber bodies 9 and outer tube 7, can not produce interference noise yet.
At decoupling zero on sound and comfortable rolling on the one hand, and good on the other hand driving dynamics characteristic, spindle guide depends on that to bearing 5 direction is provided with different bearing rigidities.Under power and situation about acting on the back axle 1 with advancing the travel direction contrary, the situation that the rigidity C1 of rubber bodies 9 acts on travel direction less than power (rigidity C2).As in Fig. 2, exemplarily illustrating, particularly can utilize the depression 18 and 19 of the different sizes on first section 15 of rubber bodies 9 to realize different rigidity, wherein before kernel 13, be provided with bigger depression 18 along the travel direction that advances at less rigidity C1, and at bigger rigidity C2 in the past the mode of sailing be that benchmark is provided with less depression 19 after kernel 13, depression perhaps not is set.But also kernel 13 and/or outer tube 7 be can asymmetricly dispose, rigidity C1 different on the automobile longitudinal and C2 are implemented in thus, perhaps that measures first mentioned is combined.Rigidity C1 and C2 with respect to travel direction also can have other towards, for example with illustrated embodiment towards opposite.
Mainly second section 16 by rubber bodies 9 supports side force, and the rigidity of this rubber bodies is represented with C3 in Fig. 2.In addition, the size of this rubber bodies makes that through suitably selecting rubber bodies 9 can not cut off by stop washer 14 when back axle 1 flexibly moves.
At length set forth the present invention by embodiment above.But the present invention is not limited thereto, but comprise all design plans that are defined by the claims.
