Wheel suspension for motor vehicles

摘要

The invention relates to a wheel suspension for motor vehicles, with at least one upper transverse arm and two lower separated transverse arms per wheel, which are each arranged at a defined angle to one another and are articulated to the body of the vehicle and also to a wheel carrier, furthermore with a track rod which acts on the steering lever of the wheel carrier and with a McPherson strut unit which, aligned at a defined angle to the vertical, is coupled to the body of the vehicle and to the forward lower transverse arm via a rubber-metal sleeve bearing. To achieve improved driving comfort of the motor vehicle it is suggested that at least the forward lower transverse arm (12) is arranged such that the coupling point (12c) of the McPherson strut unit (20) on the transverse arm (12) when the wheel is deflected viewed in the transverse direction of the vehicle (30) runs parallel to the longitudinal axis (28) of the McPherson strut unit (20).

1. A wheel suspension for a motor vehicle, comprising:
a wheel carrier comprising a wheel flange; a first lower separate suspension link and a second lower separate suspension link (12, 14) per wheel carrier arranged at a defined angle to each other and articulated to the body of the motor vehicle and also to a wheel carrier (16), wherein the first lower suspension link comprises a forward lower transverse arm having a first end and a second end, the forward lower transverse arm first end pivotally connected to the wheel carrier at a first pivot point of the wheel carrier and located on or in proximity to a center vertical axis of said wheel flange and the wheel carrier, the forward lower transverse arm second end pivotally connectable to the body of the vehicle, the forward lower arm having a longitudinal centerline positioned essentially in a transverse direction of the motor vehicle relative to a transverse axis of the vehicle extending through the wheel flange; wherein the second lower suspension link comprises a rear lower transverse arm having a rear lower arm first end and a rear lower transverse arm second end, the rear lower transverse arm first end pivotally connected to the wheel carrier at a second pivot point of the wheel carrier, the rear lower transverse arm second end pivotally connectable to the body, the rear lower transverse arm having a longitudinal centerline set at a rearward angle relative to the centerline of the forward lower arm; the wheel carrier having opposed first and second sides, the wheel flange on the first side, the first and second pivot points on the second side; and a McPherson strut pivotally connected by a rubber metal sleeve joint to the forward lower transverse arm adjacent to the wheel carrier and connectable to the body, the McPherson strut being aligned with the center vertical axis of the wheel flange and the wheel carrier, wherein the McPherson strut is disposed relative to the forward lower transverse arm and the centerlines of the lower transverse arms are skewed relative to each other to be slightly out of a horizontal plane, and a plane that contains both lower transverse arm centerlines is disposed at or nearly perpendicular to a longitudinal centerline of the strut viewed in the transverse direction of the vehicle, wherein the front suspension link is arranged such that while the suspension is mounted on the vehicle and the wheel carrier deflects and/or is steered, a center point of the pivotal connection of the McPherson strut on the forward lower transverse arm viewed in a transverse direction of the vehicle is displaced along a line of travel disposed adjacent to the longitudinal centerline of the McPherson strut approximately parallel to the longitudinal centerline axis of the McPherson strut.
