First Claim
Patent Images
1. A suspension system for a laterally tiltable, multitrack vehicle, comprising:
- first and second steering knuckles;
a first set of control arms connected to the first steering knuckle;
a second set of control arms connected to the second steering knuckle, each of the first and second sets of control arms comprising upper and lower control arms,wherein the upper control arm of each set is parallel to the lower control arm of each set;
a spring/damper element extending between and connected to each of the lower control arms and/or each of the upper control arms of the first and second sets of control arms; and
a balancer system,wherein the balancer system is configured to provide a first load path for torque and the spring/damper element is configured to provide a second load path, which differs from the first load path, for suspension and road loads.

Abstract
A laterally tiltable, multitrack vehicle suspension may include first and second steering knuckles. The suspension may also include a first set of control arms connected to the first steering knuckle and a second set of control arms connected to the second steering knuckle. Each of the first and second sets of control arms may include upper and lower control arms. The suspension may further include a spring/damper element acting between the first and second sets of control arms and a balancer system.

13. A suspension system for a laterally tiltable, multitrack vehicle, comprising:
-
first and second steering knuckles respectively disposed within internal spaces of first and second front wheels of the vehicle; a first set of control arms connected to the first steering knuckle and extending between the first steering knuckle and a frame rail of the vehicle; a second set of control arms connected to the second steering knuckle and extending between the second steering knuckle and a frame rail of the vehicle, wherein each of the first and second sets of control arms comprises an upper control arm connected to an upper end of the respective steering knuckle and a lower control arm connected to a lower end of the respective steering knuckle; a spring/damper element extending between and connected to each of the lower control arms and/or each of the upper control arms of the first and second sets of control arms, wherein the spring/damper element is parallel to the lower control arms and/or the upper control arms; and a balancer system configured to create a torque to influence a leaning angle of the vehicle, wherein the balancer system is configured to provide a first load path for the torque and the spring/damper element is configured to provide a second load path, which differs from the first load path, for suspension and road loads. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of stabilizing a tiltable, multitrack vehicle, the method comprising:
-
distributing a first load along a first load path during a roll motion of the vehicle; and distributing a second load along a second load path during a jounce/rebound motion of the vehicle, the second load path differing from the first load path, wherein distributing the first load influences a leaning angle of the vehicle, and wherein distributing the second load enables vertical wheel motion and suppresses a resonant vertical motion of the vehicle. - View Dependent Claims (21, 22)
