Embodiment Construction

[0025] figure 1 A tie rod 1 of the wheel suspension is shown. The wheel suspension itself is not shown. The operation and connection of the tie rod 1 is well known, so its details will not be repeated here.

[0026] The tie rod 1 is formed from two rod parts 2 and 3 . The rod part on the left in the plane of the drawing, ie the first rod part 2, has a compensation space 4 which, viewed in radial section (for example towards the right-hand side of the plane of the drawing), has a cylindrical design and one end Open your mouth.

[0027] The compensation space 4 is filled with a compensation medium, preferably a fluid, more preferably hydraulic oil. To seal off this compensation space 4 a cap-shaped end cap 6 is provided, which will be described in more detail below.

[0028] The other right-hand end in the plane of the illustration, that is to say the engagement end of the second rod part 3 , passes through the end cap 6 and into the compensation space 4 .

[0029] For exa...

Abstract

The invention relates to a wheel suspension for a motor vehicle, which has a tie rod (1) formed from two rod parts (2, 3). In order to achieve speed-dependent adaptation of the compliance of the tie rod, the proposal is that the first rod part (2) have a compensating space (4) filled with a compensating medium, in which the other, second rod part (3) is arranged by means of the engagement end (7) thereof, the compensating space (4) being connected to a, preferably pressurized, medium reservoir (18) via a switching element (17) arranged at a connecting element (19).

Description

technical field [0001] The invention relates to a wheel suspension of a motor vehicle having a tie rod formed from two rod parts. Such wheel suspensions are used in motor vehicles, for example on output axles. Background technique [0002] There are many aspects to consider when designing this type of wheel suspension. On the one hand, there should be very precise steering feel at low or moderate vehicle speeds. For this purpose, relatively stiff tie and thrust rods with little elasticity or flexibility would be required. However, this results in overresponsive steering at high vehicle speeds, making the steering relatively too sensitive, which is an unpleasant experience for the user. So at high speeds it would be better if the tie rods were more flexible and the thrust rods had better elasticity or flexibility. The ideal wheel suspension thus falls within the range between good steering responsiveness at low vehicle speeds and high stability at high vehicle speeds. ...
