Definitions
- the invention relates to a wheel suspension for motor vehicles according to the preamble of claim 1 .
- a wheel suspension such as this is shown, for example, in DE 38 43 613 A1 in which the lower and optionally the upper transverse arm of the wheel guidance are individual transverse arms which, in conjunction with a track rod which is articulated to the body or to the steering of the motor vehicle, form track-stable wheel guidance.
- the advantage of such a wheel suspension with detached transverse arms lies especially in formation of a virtual steering axle which, for the most part, can be designed independently of structural constraints so that favorable axle values such as camber, axle pin rake, roll radius, and the disturbing-force lever arm for the driven wheels (dimension a), etc. are adjustable.
- McPherson strut unit In conjunction with the spring system and damping of the motor vehicle there can be a McPherson strut unit with a telescoping shock absorber which is coupled in a structurally favorable manner to the forward lower transverse arm of the wheel suspension by way of a rubber-metal sleeve bearing.
- the object of the invention is to propose a wheel suspension of the generic type which is further improved with respect to driving comfort.
- At least the front lower transverse arm is arranged such that the coupling point of the McPherson strut unit on the transverse arm when the wheel is deflected, viewed in the transverse direction of the vehicle, runs parallel to the longitudinal axis of the McPherson strut unit.
- a design of the wheel suspension which is also advantageous with respect to the other driving properties of the motor vehicle consists in that the lower forward transverse arm is positioned essentially in the transverse direction of the motor vehicle and the rear lower transverse arm is positioned approx. 45° to the rear tilted inside thereto.
- the body-side bearing points of the lower transverse arms can be aligned essentially horizontally at the same height, with which unwanted migration of the indicated lower bearing point of the McPherson strut unit over the entire spring path of the wheel suspension is likewise advantageously avoided.
- the tilt of the McPherson strut unit can be approx. 5 to 10 degrees up to the rear and up to the inside in order to effect easily manageable matching of the wheel-guiding transverse arms to the McPherson strut unit, in addition to a structurally favorable arrangement of the McPherson strut unit.
- the horizontal plane defined by the two lower transverse arms can also be aligned perpendicular to the tilt of the McPherson strut unit viewed in the transverse direction of the vehicle by a suitable design of the wheel carrier-side coupling points.
- the body-side bearing of the forward lower transverse arm in the transverse direction of the motor vehicle can be made stiffer than in the direction of the longitudinal axis of the McPherson strut unit. This results in an additional improvement of driving comfort and the damping properties of the wheel suspension relative to the body of the vehicle without adversely affecting the guiding properties of the forward transverse arm.
- FIG. 1 shows, with one wheel carrier, two lower, detached transverse arms, a suggested track rod and a McPherson strut unit;
- FIG. 2 shows a side view S of FIG. 1 of the wheel suspension
- FIG. 3 shows a top view of the wheel arrangement as shown in FIGS. 1 and 2 .
- FIGS. 1 to 3 show the lower plane of the front left wheel suspension 10 for motor vehicles, which wheel suspension is composed essentially of two lower, individual transverse arms 12 , 14 , one wheel carrier 16 , a track rod 18 which is only suggested, and a McPherson strut unit 20 .
- the direction of travel of the motor vehicle is indicated by F.
- the wheel which is not shown is attached to the wheel flange 22 which is pivoted-mounted in the wheel carrier 16 .
- the transverse arms 12 , 14 are separate transverse arms which are coupled to the body of the motor vehicle which is not shown (or an auxiliary frame) via angularly movable rubber-metal sleeve joints 12 a , 14 a and to the wheel carrier 16 via ball joints 12 b , 14 b (compare FIG. 2 ).
- the third wheel guiding element located in the lower plane of the wheel suspension 10 is the track rod 18 which is connected via a ball joint 18 a to a steering means of the motor vehicle which is not shown and also is coupled to one steering arm 16 a of the wheel carrier 16 via a ball joint 18 b.
- the track rod 18 is coupled to the body as a further transverse arm.
- the McPherson strut unit 20 is conventionally composed of a telescoping shock absorber 24 and a helical compression spring or support spring 26 which coaxially surrounds the shock absorber.
- the piston rod 24 a of the shock absorber 24 is coupled via an absorber bearing which is not shown to a bearing bracket or directly to the body of the motor vehicle on which the upper end of the support spring 26 is also supported.
- the lower end of the support spring 26 is supported via a spring plate on the absorber cylinder 24 b of the shock absorber 24 .
- the absorber cylinder 24 b of the shock absorber 24 is furthermore coupled to the forward transverse arm 12 referred to as the support rod 12 below via a support part 24 c which is made slightly arc-shaped with a fork-shaped connecting part 24 d with interposition of a rubber-metal sleevejoint 12 c in the vicinity of the wheel carrier 16 .
- the axis of the sleevejoint 12 c is aligned like the pertinent attachment screw 17 in the longitudinal direction of the motor vehicle.
- the forward lower transverse arm or support rod 12 at this point is arranged such that the coupling point 12 c (center point of the sleeve joint 12 c ) of the McPherson strut unit 20 on the support rod 12 when the wheel is deflected (spring path s) viewed in the transverse direction of the vehicle (compare FIG. 2 ) runs at least approximately parallel to the longitudinal axis (dot-dash line 28 ) of the McPherson strut unit 20 .
- the longitudinal axis 28 of the McPherson strut unit 20 therefore changes only little over the deflection path of the wheel suspension 10 on 28 a and does not cause squeezing of the sleeve joint 12 c or unilaterally acting moments of the support spring 26 on the shock absorber 24 .
- the support rod 12 is positioned with a deviation of approx. 4 degrees (angle a), that is, more or less in the transverse direction of the motor vehicle (dot-dash line 30 ), and the rear lower transverse arm is positioned approx. 45 degrees (angle 3 ) to the rear tilted inside thereto.
- body-side bearing points 12 a , 14 a , and their rubber-metal sleeve joints 12 a , 14 a of the lower transverse arms 12 , 14 are aligned essentially horizontally at about the same height.
- the tilt of the McPherson strut unit 20 relative to the vertical is moreover 5 to 10 degrees up and to the rear and up to the inside, as is to be seen from FIGS. 2 and 3 .
- the two lower transverse arms are arranged skewed to one another. Their alignment is chosen such that parallel displacement of the lower rear transverse arm with the wheel-side articulation point 14 b into the articulation point 12 b of the support rod with the latter yields a plane which is almost perpendicular to the illustrated tilt (approx. 5 degrees) of the McPherson strut unit 20 viewed in the transverse direction of the vehicle 20 .
- the body-side bearing 12 a of the forward lower support rod 12 in the transverse direction 30 of the vehicle is designed to be stiffer than in the direction of the longitudinal axis 28 of the McPherson strut unit 20 (that is, in the vertical axis).
- These “spread” sleeve bearings are prior art and can have, for example, material-weakening lobes (in the vertical axis) or material-strengthening metal inserts (in the transverse axis), etc., and therefore are not shown.
