Abstract
Abstract An independent suspension for steered wheels of motor vehicles in which the wheel carrier that serves for the guidance of the wheel during spring and steering movements is connected with the vehicle superstructure in its lower area by means of a cross guide member and in its upper area by way of two individual guide members for achieving an ideal steering axis; the symmetry line with respect to the two upper guide members thereby subtends in the straight driving position of the wheel--as viewed in plan view--an acute angle to the wheel axis and is located to the rear of the wheel axis as viewed in the driving direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
An independent wheel suspension for a steered wheel of a motor vehicle, comprising wheel carrier means, means for guiding the wheel during spring and steering movements including transverse guide means operatively connecting the lower area of the wheel carrier means with a vehicle superstructure and two individual guide members operatively connecting the upper area of the wheel carrier means with the vehicle superstructure, the wheel being pivotal about an ideal instantaneous pivot axis which results from line of intersection of the two planes that are defined respectively by the lower pivot paint at the wheel carrier means and the two axes of the upper guide members, characterized in that--as viewed in plan view--the symmetry line with respect to the upper two guide members subtends in the straight driving position of the wheel an acute angle to the wheel axis and is located to the rear of the wheel axis as viewed in the driving direction.
Claim 2
Dependent Claim
155 words
An independent wheel suspension for a steered wheel of a motor vehicle, comprising wheel carrier means, means for guiding the wheel during spring and steering movements including transverse guide means operatively connecting the lower area of the wheel carrier means with a vehicle superstructure and two individual guide members operatively connecting the upper area of the wheel carrier means with the vehicle superstructure, the wheel being pivotal about an ideal instantaneous pivot axis which results from line of intersection of the two planes that are defined respectively by the lower pivot paint at the wheel carrier means and the two axes of the upper guide members, characterized in that--as viewed in plan view--the symmetry line with respect to the upper two guide members subtends in the straight driving position of the wheel an acute angle to the wheel axis and is located to the rear of the wheel axis as viewed in the driving direction.
Claim 3
Dependent Claim
23 words
A wheel suspension according to claim 1, characterized in that both upper guide members are located to the rear of the wheel axis.
Claim 4
Dependent Claim
75 words
A wheel suspension according to claim 1 or 2, characterized in that the symmetry line with respect to the two upper guide members corresponding to the straight driving position of the wheel is approximately perpendicular to the wheel center plane of the wheel deflected maximum toward the outside of the curve--as viewed in plan view--and extends approximately parallel to the wheel center plane of the wheel when deflected maximum toward the inside of the curve.
