Abstract
Official abstract text for this publication.
A wheel suspension for a vehicle, comprising: at least one wheel guiding element which connects a steering knuckle to a vehicle bodywork, and a spring-based and/or vibration-based damping element functioning like a shock-absorber strut or a suspension strut or a spiral spring, wherein the spring-based and/or vibration-based damping element is connected to the steering knuckle, wherein the wheel guiding element has a through-opening in the vehicle vertical direction, and wherein the spring-based and/or vibration-based damping element is located such that it protrudes through the through-opening.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wheel suspension for a vehicle, comprising: a first wheel guiding element which connects a wheel carrier to a vehicle body, the first wheel guiding element being i) arranged in a lower link plane positioned below a wheel rotation axis, ii) oriented at least approximately in a vehicle transverse direction, and iii) arranged in front of a wheel center axis in a vehicle direction of travel when viewed during forward travel, a second wheel guiding element, which is i) arranged in the lower link plane positioned below a wheel rotation axis, ii) oriented at least approximately in the vehicle transverse direction, and iii) arranged behind the wheel center axis in the vehicle direction of travel when viewed during forward travel, and a spring and/or a vibration damper element in the form of a damper strut or a spring strut or a helical spring, wherein the spring and/or vibration damper element is connected to the wheel carrier from below the connection of the first wheel guiding element to the wheel carrier when viewed in a vehicle vertical direction, wherein the first wheel guiding element comprises a passage opening in a vehicle vertical direction, and, wherein the spring and/or the vibration damper element is arranged projecting through the passage opening. 2. The wheel suspension according to claim 1 , wherein the spring and/or vibration damper element, which projects through the first wheel guiding element, is a damper strut, and wherein a helical spring is connected to the second wheel guiding element. 3. The wheel suspension according to claim 1 , wherein the passage opening on the first wheel guiding element is configured such that the spring and/or vibration damper element project through the passage opening in a freely moveable manner during any spring and/or steering movements.
