Rear suspension systems for laterally tiltable multitrack vehicles
First Claim
Patent Images
1. A rear suspension for a laterally tiltable, multitrack vehicle, comprising:
- first and second balancer systems extending transversely between and independently connecting first and second trailing arms to form first and second independent load paths, respectively,wherein the first balancer system creates a torque along the first load path to influence a leaning angle of the vehicle and the second balancer system suppresses a resonant vertical motion of the vehicle along the second load path.

Abstract
A rear suspension system for a laterally tiltable, multitrack vehicle may include first and second trailing arms. The rear suspension system may further include first and second balancer systems acting between the first and second trailing arms. The first balancer system may create a torque to influence a leaning angle of the vehicle when the suspension system is in use. The second balancer system may suppress a resonant vertical motion of the vehicle when the suspension system is in use.

16. A rear suspension for a laterally tiltable, multitrack vehicle, comprising:
-
first and second trailing arms, each of the first and second trailing arms extending between a rear wheel of the vehicle and a frame rail of the vehicle; a first balancer system extending transversely between and connected to each of the first and second trailing arms, the first balancer system being configured to create a torque to influence a leaning angle of a body of the vehicle and to provide a first load path for the torque; and a second balancer system extending transversely between and connected to each of the first and second trailing arms, the second balancer system being configured to provide a second load path for suspension and road loads and to suppress a resonant vertical motion of the body of the vehicle caused by the suspension and road loads, wherein each of the first and second load paths links the first trailing arm to the second trailing arm, and wherein the first balancer system is connected to each of the first and second trailing arms at a different location than the second balancer system such that the first load path is separate and distinct from the second load path. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method of stabilizing a tiltable, multitrack vehicle comprising a first rear wheel mounted to a first rear trailing arm and a second rear wheel mounted to a second rear trailing arm, the method comprising:
-
distributing a first load via a first balancer system during a roll motion of the vehicle to influence a leaning angle of the vehicle, the first balancer system being connected to each of the first rear trailing arm and the second rear trailing arm; and distributing a second load via a second balancer system during a jounce/rebound motion of the vehicle to suppresses a resonant vertical motion of the vehicle, the second balancer system being connected to each of the first rear trailing arm and the second rear trailing arm at a different location than the first balancer system such that a load path of the first balancer system, which links the rear trailing arms, is separate and distinct from a load path of the second balancer system, which links the rear trailing arms.

25. A rear suspension for a laterally tiltable, multitrack vehicle, comprising:
-
first and second balancer systems, the first balancer system comprising a first balancer control arm and the second balancer system comprising a second balancer control arm, the first and second balancer controls arms extending adjacent to one another in parallel transversely between and independently connected to each of first and second trailing arms, the first balancer system being configured to create a torque along a first load path to influence a leaning angle of the vehicle, and the second balancer system being configured to suppress a resonant vertical motion of the vehicle along a second, independent load path.
