Wheel suspension for motor vehicles

Abstract

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 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.

1 . A wheel suspension for motor vehicles, with two lower separate transverse arms per wheel, which are arranged at a defined angle (β) to one another and are articulated to the body of the vehicle and also to a wheel carrier, furthermore 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 coupling point wherein at least the forward lower transverse arm is arranged such that the coupling point of the McPherson strut unit on the transverse arm when the wheel is deflected and/or steered viewed in the transverse direction of the vehicle runs within an angle between 0 and 5 degrees, to the longitudinal axis of the McPherson strut unit. 
   
   
       2 . The wheel suspension according to  claim 1 , wherein the lower forward transverse arm is positioned essentially in the transverse direction of the motor vehicle and the rear lower transverse arm is positioned substantially 45 degrees to the rear tilted inside thereto. 
   
   
       3 . The wheel suspension according to  claims 1  wherein the body-side bearing points of the lower transverse arms are aligned essentially horizontally and substantially at the same height. 
   
   
       4 . The wheel suspension according to  claim 1  wherein the tilt of the McPherson strut unit relative to vertical is aligned within a range of 5 to 10 degrees up to the rear and up to the inside. 
   
   
       5 . The wheel suspension according to  claim 4 , wherein the horizontal plane defined by the two lower transverse arms is aligned almost perpendicular to the tilt of the McPherson strut unit viewed in the transverse direction of the vehicle. 
   
   
       6 . The wheel suspension according to  claim 1 , wherein the body-side joint of the forward lower transverse arm in the transverse direction of the vehicle is designed to be stiffer than in the direction of the longitudinal axis of the McPherson strut unit.
