Description

[0001] The invention relates to a torsion bar bearing for arranging a torsion bar on a vehicle section, comprising a bearing section that at least partially surrounds the torsion bar, and a holder that holds the bearing section on the vehicle section.

[0002] Torsion bar bearings, also known as stabilizer bushings, are used in motor vehicles to improve cornering stability. When cornering, which is controlled by the steering system, one of the wheels tends to lose or even lose contact with the road. This roll can be reduced or, ideally, prevented by the interaction of the torsion bar with a torsion bar bearing or stabilizer bushing. The torsion bar bearing can hold the torsion bar stationary relative to a section of the vehicle – thus preventing translational movement – ​​while a torsional movement of the torsion bar can absorb roll, particularly when cornering.

[0003] From EP 3 530 500 A1, a torsion bar bearing is known that prevents translational movement of the torsion bar relative to the vehicle body when cornering, but unfortunately also allows little or no torsion of the torsion bar. Here, the torsion bar itself has to absorb the torsional movement, which can lead to increased stress on the mechanism when cornering.

[0004] From JP 6368728 B2, a torsion bar bearing is also known which holds the torsion bar in the radial direction with respect to the vehicle body, but also hardly allows any torsion without a mechanical load on the torsion bar in its free, unsupported area. That is, translational movement of the torsion bar is prevented without allowing torsional movement.

[0005] According to WO 2007 / 126359 A1, a mounting for a torsion bar on a vehicle body is proposed, in which two different bearing sections are provided. Here, the torsion bar itself is purely cylindrical in one section and has a constriction at another, which corresponds to a bulge on the bearing section. This also provides a translationally rigid or stiff mounting, which is advantageous. However, during torsional movements of the torsion bar, hardly any additional clearance can be provided within the bearing.

[0006] A corresponding torsion bar bearing is also known from JP 2012-162171 A, which has the same properties as the prior art discussed above, i.e., in addition to a desired translational stiffness of the bearing, a high torsional stiffness is also offered in an undesirable way.

[0007] The state of the art described above thus has in common that, on the one hand, a high stiffness is provided in the radial direction in order to minimize translational movement of the torsion bar relative to the vehicle section, and on the other hand, a disadvantageously high stiffness is also required in the torsion bar bearing for torsional movements, which does not tolerate rolls.

[0008] According to the invention, an improved torsion bar bearing is to be provided.

[0009] According to the invention, a torsion bar bearing with the features of claim 1 is provided, wherein the torsion bar bearing according to the invention has a torsion bar movement tolerance section configured to allow torsional movement of the torsion bar, but which is relatively stiff with respect to translational movement of the torsion bar relative to the vehicle body. The torsion bar movement tolerance section comprises a torsional tolerance geometry that accommodates torsional movement of the torsion bar.

[0010] This means that a torsion bar bearing according to the invention allows the torsion bar to absorb torsional twisting, while reducing radial movement of the torsion bar in relation to the vehicle body, thereby reducing vehicle roll.

[0011] Advantageously, the torsional tolerance geometry provides at least one clearance that extends section by section and / or partially around the cylinder axis of the torsion bar. This means that torsion of the torsion bar can be compensated within this clearance, while at the same time translational movement of the torsion bar is reduced and ideally prevented by stops. In this case, the torsion bar itself can be relieved of torsion, and the ground contact of the vehicle's wheels can be intensified. This can mitigate body roll.

[0012] The arrangement of one or more clearances between an area associated with the torsion bar and an area associated with the support at specific points, which movably accommodate stops acting in the translational direction but in the torsional direction, is of lesser importance. What is more important is that the clearances, with their respective stops that have a limiting effect in the translational direction, provide torsional freedom to the area of ​​the torsion bar bearing associated with the torsion bar. The pattern of the clearances and their respective stops acting in the translational direction around the torsion bar is, within limits, arbitrary. These clearances and stops can be uniformly or unevenly distributed around the circumference of the torsion bar, or, for example, to accommodate specific loads acting on the torsion bar, they can be more numerous in the lower region of the torsion bar bearing.The arrangement can also be triangular, square, etc. in cross-section.

[0013] Advantageously, at least one translational movement limiting element is assigned to the torsion bar, which can advantageously be designed as a stop within the torsion bar bearing or on the torsion bar itself.

[0014] According to one embodiment, the bearing section can advantageously be connected to the torsion bar, for example by bonding, with the free space being provided in the torsion bar bearing holder, i.e., in a retaining clamp. The holder or retaining clamp fixes the torsion bar bearing according to the invention to the vehicle itself. The translational movement limiting element, for example a stop, can be arranged on an outer circumference of the bearing section facing the retaining clamp, or vice versa.

[0015] The clearance(s) are provided on or within the bearing section, while the translational movement limiting element(s) can be located on the torsion bar or on a component connected to it, for example, bonded. Advantageously, the torsion bar bearing according to the invention comprises a damping section, for example, a damping sleeve, which is made of a damping material and is inserted between the torsion bar and the support, for example, a clamp. Rubber or a plastic can be used here. A corresponding damping section or damping sleeve can also consist of several layers that are intermediately mounted at different radial distances around the torsion bar and thus between the torsion bar and the support, for example, a clamp.

[0016] With regard to the invention, it can be seen that by providing a free space for the torsion bar that acts in the direction of torsion, a torsional movement of the torsion bar can be completely or partially compensated, while the entire construction of the torsion bar bearing according to the invention greatly reduces and, in the best case, prevents a translational movement of the torsion bar, i.e., a movement of the torsion bar from the vehicle body outwards, inwards, upwards or downwards.

[0017] Another embodiment according to the invention replaces the aforementioned clearance and stop with the rigidity of a bearing sleeve, in particular a rubber sleeve, which is connected to the torsion bar, especially by bonding. This rubber sleeve is selectively blocked radially and in any case axially with respect to the torsion bar, i.e., the material of the rubber sleeve cannot deflect or flow, at least in the axial direction. Thus, the desired torsional movement takes place within the material of the rubber sleeve, while deflection of the material in the axial direction of the torsion bar is blocked, which provides the desired stiffness against translational movements and combines this with the highly advantageous freedom from torsional forces.The rubber sheath thus provides the space that allows for torsional movement, while the at least axial encapsulation of the rubber sheath material blocks the advantageous radial stiffness by axially and, if necessary, radially preventing any evasive movement of the rubber material of the rubber sheath connected to the torsion bar. The axial blocking section also contributes to preventing translational movements of the torsion bar.

[0018] Advantageously, additional torsional flexibility can be provided in the bearing shell for the torsion bar by distributing clearances symmetrically or asymmetrically around the circumference of the torsion bar within the bearing shell. To enable the most uniform torsional movement possible through the bearing shell, particularly a rubber shell, these clearances should be distributed symmetrically around the circumference of the torsion bar.

[0019] TPE material could also be used in combination with rubber or separately instead of rubber.

[0020] The present invention is explained in more detail below with reference to the accompanying figures. Reference numerals denote identical or at least functionally equivalent components of the torsion bar bearing according to the invention.

The Fig. 5a shows a side view of the embodiment according to Fig. 5 in the direction of the cylinder axis of the torsion bar. Fig. 5b shows a section BB through the representation according to Fig. 5a. Fig. 5c shows a section AA through the embodiment according to the Fig. 5a.

[0021] In general, with reference to all embodiments discussed below, it can be disclosed that the Shore hardness of the rubber or TPE plastic material to be used can be in the range of 42 to 65 ShA for bearing and damping components. Mounts, clamps, and housings can be made of metal or harder plastic.

[0022] The figures show the components of embodiments according to the invention in an uncompressed, i.e., uncalibrated, state, in which some manufacturing-related overlaps are visible, which disappear in the installed state. Thus, a torsion bar bearing may comprise a larger volume of permanently elastic material than is available to it in the installed state. This means that the permanently elastic material is compressed during installation, since the installation space of a bracket or clamp for the torsion bar bearing according to the invention is smaller than the torsion bar bearing itself in its uncompressed state.

[0023] For the sake of clarity, a torsion bar 12 is shown in the figures only as a section. This local section is the area of ​​the torsion bar 12 that also interacts with the torsion bar bearing.

[0024] The Fig. Figure 1 shows a torsion bar bearing according to the invention, generally designated by reference numeral 10. The torsion bar bearing 10, also called a stabilizer bushing, comprises a torsion bar 12 surrounded by a damping sleeve 24. The damping sleeve 24 can be made of a permanently elastic material, such as rubber, TPE, or the like, to absorb vibrations and thus dampen and suppress noise. Two half-shells 16 are integrated into the damping sleeve 24, each having stops 18a and 18b that prevent translation of the torsion bar 12 in the direction R. (Direction R points in Fig. (1 upwards) The stops 18a and 18b are received in torsional tolerance geometries 20, which are designed here as clearances. A clamp 14 is arranged around the outside of the damping jacket 24, which holds the torsion bar bearing 10 according to the invention to a vehicle body (not shown) by means of bolts, for example screw bolts.

[0025] The free spaces 20 can also be formed next to the stops in the damping shell, as long as a desired functional relationship is provided. This relationship exists between the translational limiting function provided by the stops 18a, 18b and the torsional freedom of movement of the torsion bar to be accommodated by the free spaces 20, which is not or only partially accommodated by the material of the damping shell 24.

[0026] The damping sheath 24 is rigidly connected to the torsion bar, for example by gluing, so that relative movements between the two components are not possible, while torsion is enabled by the free spaces 20 within these, with the stops 18a, 18b defining the rotational movement free space in the direction of a rotational movement.

[0027] The Fig. Figure 1a shows a longitudinal section through the embodiment of a torsion bar bearing 10 according to the invention. Fig. 1 through the section plane AA. The clamp 14 is held on a vehicle body (not shown) via mounting holes 22, through which bolts, such as screw bolts (not shown), are passed.

[0028] The torsion bar 12 is in the Fig. 1 to Fig. 1b, usually connected to the damping jacket 24 and the half-shells, for example by gluing and / or connecting via bolts.

[0029] Regarding the Fig. 1a It should also be noted that the fastening holes 22 are only recognizable because the components of the clamp 14, which have the fastening holes 22, are shown in a top view.

[0030] The sectional view, which is positioned in the longitudinal direction of the torsion bar 12, i.e. along the cylinder axis Z of the torsion bar 12, reveals both the half-shells 16 and the stops 18a, 18b, which are incorporated in the tolerance geometries 20 to allow a torsional movement.

[0031] The half-shells 16 divide the damping shell 24 such that two spring components 24a and 24b are generated from the damping shell, providing the desired translational stiffness and torsional freedom. These bearing properties can be adjusted by the thickness of the two spring components and the choice of material.

[0032] In all figures, references to axial directions refer to the axis Z and references to a radial direction refer to the outward direction from the torsion bar 12 along the arrow R in Fig. 1.

[0033] The respective side boundaries 26 hold the components of the torsion bar bearing 10 together in a fixed position in the direction of the cylinder axis Z of the torsion bar according to the invention.

[0034] In the Fig. 1c and Fig. 1d a hemisphere 16 is recognizable, as shown in the Fig. 1 to 1b are used. A stop 18a on the half-shell 16 is shown both in the front view according to Fig. 1c as well as in the perspective view according to Fig. 1d recognizable.

[0035] The front view according to Fig. Figure 2 shows another embodiment of a torsion bar bearing 10' according to the invention.

[0036] The torsion bar bearing 10' includes a clearance that corresponds to a torsion bar section 12. In its end position, the torsion bar section 12 is connected or bonded to a damping sleeve 24, which can be composed of two halves. The halves of the damping sleeve 24 are provided with clearances 20. The stops 18a support the torsion bar 12 in the translational direction and impart high stiffness to the torsion bar in the radial direction R, i.e., the torsion bar can hardly or not at all deflect in the direction R during operation, resulting in high stiffness against translational movements of the torsion bar 12. Cylindrical clearances 20 are shown schematically. The stops are formed here by means of a Fig. 2a and Fig. 2d shown groove 21 in the clamp 14 provided.

[0037] The open spaces 20 interact with the grooves 21 (see Fig. 2a, Fig. 2d) trained stops in the clamp 14 according to Fig. 2a together, which make a section AA through the embodiment according to Fig. 2 represents.

[0038] The damping jacket 24 is attached to the torsion bar section 12 according to Fig. 2a are glued on, or otherwise permanently connected to it. The stops 18a work together to create torsional freedom, which allows the torsion bar section 12 to be provided with freedom of movement in the torsional direction.

[0039] The BB cut according to Fig. 2b, whose location in Fig. Figure 2 also shows the torsion bar 12, which is fixedly connected to the damping sleeve 24. The clamp 14 is also visible, specifically in the upper area of ​​the Fig. 2b in perspective.

[0040] In Fig. Figure 2c shows the stops 18a and 18b of the clamp 14 in perspective. The entire torsion bar bearing 10' can be attached to a vehicle via mounting holes 22 in the clamp 14 to keep the torsion bar (not shown here) translationally rigid and capable of torsional movement.

[0041] The Fig. Figure 2d shows the bell 14 in a perspective view, with the stops 18a, 18b again shown schematically in perspective.

[0042] Another embodiment of a torsion bar bearing 10" is described in the Fig. 3 shown in a front view.

[0043] In this embodiment, a torsion bar 12 is also held rotationally fixed in direction R during operation, but can perform a torsional movement within limits.

[0044] In plan view according to Fig. 3. Clear spaces 20 are visible, extending around the torsion bar 12. The clear spaces 20 are molded together with the torsion bar 12 into a material, preferably rubber, wherein the clear spaces 20 are assigned respective stops 18a, 18b, which can be designed as extensions 18a and 18b of the torsion bar 12.

[0045] As in Fig. 3a, a section AA according to Fig. 3, as can be seen, the torsion bar has 12 stops 18a, 18b which interact with the associated clearances 20 and enable a torsional movement in the torsional direction of the torsion bar. The area 29 according to Fig. 3 represents a manufacturing-related clearance. Area 31 is a marking recess 31, which can, for example, contain a manufacturer's note, a date of manufacture, or the like, and which can contain extra material. The clearance 29 is reduced or even completely eliminated by the installation and the resulting calibration.

[0046] The free spaces 20 are separated by material of the damping jacket 24 (see Fig. 3b) are arranged in relation to the stops 18a, 18b, but are functionally related to each other. That is, torsions of the torsion bar can be absorbed by the free spaces, while the stops 18a, 18b prevent translational movements.

[0047] The Fig. 3b shows a section BB according to Fig. 3, where the torsion bar 12 shows a recess 15 in this view. In this area, the torsion bar 12 can be supported by a bearing. The position of the half-shells 16 is also visible and provides partial decoupling in order to provide two spring elements 24a, 24b for the damping sleeve, which are intended to achieve the desired radial stiffness and torsional freedom. The spring element 24b of the damping sleeve is preferably bonded to the torsion bar 12 or mechanically fixed in some other way.

[0048] In Fig. Figure 3c shows the design of the torsion bar 12 in embodiment 10" of the torsion bar bearing according to the invention. The torsion bar 12 comprises a constriction 12a with a stop 18a, which is part of the torsion bar 12. The constriction 12a is filled with the damping jacket 24 in the finished torsion bar bearing. Fig. 3D shows the rotating bar 12 again in a perspective view.

[0049] In Fig. Figure 4 shows a further embodiment of a torsion bar bearing 10''', wherein a torsion bar 12 is shown schematically, surrounded by a damping sleeve 24, which preferably represents a rubber spring. The damping sleeve 24 is connected to the torsion bar 12, in particular by bonding. According to the embodiment, the clamp 14 is Fig. 4 realized by an upper clamp 14a as upper support and a lower clamp 14b as lower support.

[0050] The clamp 14 usually comprises an upper clamp 14a and a lower clamp 14b, which can be assembled, for example by being snapped or glued together.

[0051] The damping sleeve 24 can be made of a rubber material or a TPE material. Axial blocking sections 30 are provided at the ends of the clamp 14 in the direction of the cylinder axis Z of the torsion bar 12, preventing axial deflection of the damping sleeve material 24. Thus, the resulting force conditions allow torsional movement, while preventing outward (and inward) rotation of the torsion bar 12 in the radial direction R.

[0052] In the perspective representation according to Fig. 4a shows the axial blocking section 30 again more clearly. In this embodiment, the clamp 14 is designed such that the damping jacket 24 is formed according to Fig. 4 not radially blocked. However, a radial blockage of the damping jacket 24 may also be expedient in a supplementary manner, in which case the clamp 14 and the axial blocking sections 30 would form a tighter boundary around the damping jacket 24.

[0053] The Fig. Figure 4b shows again the damping jacket 24 in a section AA according to Fig. 4, wherein the blocking sections 30 are recognizable at the respective ends of the clamp 14. In Fig. 4 and Fig. 4c The hatching overlaps in an area located between the damping sleeve 24 and the clamp 14. The rubber material used is to be pre-tensioned in this area.

[0054] According to Fig. 4c is a section BB according to Fig. 4 before, where the formation of the damping sheath 24 around the torsion bar 12 can be seen again.

[0055] The torsional movement takes place in the damping jacket, which is preferably made of rubber, the hardness of which is chosen such that a relatively high radial (in direction R according to Fig. 4) Stiffness is present while torsion is permitted in the material of the damping shell 24. A material used for the bearing shell can be selected to be particularly soft in order to achieve a soft torsional bearing stiffness. The high radial bearing stiffness is achieved by the axial block sections. The hardness is preferably in the range of 42 to 65 ShA.

[0056] The embodiment 10'''' according to Fig. 5 preferably corresponds to a variant of the embodiment according to Fig. 4.

[0057] The embodiment 10'''' shows an isometric view of the in the Fig. Components shown in 4 to 4c include additional free spaces 20 in the damping jacket 24.

[0058] These are shown in the representation according to Fig. 5 is provided evenly along the circumference of the torsion bar in the damping sleeve 24. The damping sleeve 24, which consists of two sections, is assembled around the torsion bar 12, whereby a manufacturing-related clearance 29 may remain.

[0059] Here too, axial blocking sections 30 block the damping jacket 24 in the cylindrical-axial direction with respect to the torsion bar 12.

[0060] In addition to a material selection as specified in the embodiment according to the Fig. 4 to 4c are used, in addition to a selection of the hardness of the damping or rubber sheath 24, the free spaces 20 are provided to provide a torsional connection within the damping sheath 24.

[0061] In the Fig. 5a is a side view of the torsion bar bearing 10'''' according to Fig. Figure 5 shows that blocking sections 30 are arranged above and below the torsion bar 12, which in themselves already help to prevent translational movements of the torsion bar 12. In the damping sleeve 24, four free spaces 20 are provided symmetrically around the torsion bar 12, which allow additional torsional movements of the torsion bar, which can be rigidly connected to the parts of the damping sleeve 24, for example, by gluing.

[0062] In the Fig. 5b, which shows a section BB through the embodiment according to Fig. 5 or through the Fig. Figure 5a shows the position of the clearances 20 within the damping sleeve 24 around the outer circumference of the torsion bar 12 in greater detail. The material of the damping sleeve 24 can be selected such that its hardness and flexible properties already accommodate a torsional movement of the torsion bar relative to the torsion bar bearing itself. The additional clearances 20 can provide further torsional freedom of movement of the torsion bar relative to the bearing 14a, 14b.

[0063] The Fig. 5c shows section AA through the embodiment according to Fig. 5a, which essentially represents the features already included in the Fig. 4b can be seen, since the embodiment according to the Fig. 4 to 4c is an embodiment on which the embodiment according to the Fig. builds up to 5c.

[0064] According to the embodiment of the Fig.In sections 5 to 5c, the free spaces 20 in the axial direction of the torsion bar are not continuous through the damping shell 24. That is, depending on the thickness of the damping shell 24, they extend only 10 to 25% of the thickness of the damping shell 24 in the axial direction of the torsion bar 12 into the damping shell 24 in order to ensure the stability of the damping shell 24.
