Rear suspension systems with rotary devices for laterally tiltable multitrack vehicles
First Claim
Patent Images
1. A suspension system for a laterally tiltable, multitrack vehicle, comprising:
- a balancer system extending transversely between and connected to each of first and second trailing arms; and
a rotary device acting between and connected to each of the first and second trailing arms at a different location than the balancer system,wherein one of the balancer system and the rotary device is configured to provide a torque to influence a leaning angle of the vehicle and a first load path linking the first and second trailing arms for the torque, and the other of the balancer system and the rotary device is configured to provide a second load path linking the first and second trailing arms, which is completely separate and distinct from the first load path, for suspension and road loads and to suppress resonant vertical motion of the vehicle caused by the suspension and road loads.

Abstract
A suspension system for a laterally tiltable, multitrack vehicle may include a balancer system extending between first and second trailing arms. The suspension system may further include a rotary device acting between the trailing arms. One of the balancer system and the rotary device may be configured to provide a torque to influence a leaning angle of the vehicle and the other of the balancer system and the rotary device may be configured to suppress resonant vertical motion of the vehicle.

17. A rear suspension system 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 balancer system extending transversely between and connected to each of the first and second trailing arms, the 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 rotary spring/damper element acting between and connected to each of the first and second trailing arms at a different location than the balancer system, the rotary spring/damper element being configured to provide a second load path, which is completely separate and distinct from the first 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. - View Dependent Claims (18, 19, 20)

21. A rear suspension system 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 balancer system extending transversely between and connected to each of the first and second trailing arms, the balancer system being configured to provide a first load path for suspension and road loads and to suppress a resonant vertical motion of a body of the vehicle caused by the suspension and road loads; and a rotary actuator acting between and connected to each of the first and second trailing arms at a different location than the balancer system, the rotary actuator being configured to create a torque to influence a leaning angle of the body of the vehicle and to provide a second load path, which is completely separate and distinct from the first load path, for the torque. - View Dependent Claims (22)

23. 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, during a roll motion of the vehicle, via a first mechanism positioned within a rear suspension of the vehicle to influence a leaning angle of the vehicle; and distributing a second load, during a jounce/rebound motion of the vehicle, via a second mechanism positioned within the rear suspension of the vehicle to suppress a resonant vertical motion of the vehicle, wherein the second mechanism is connected to each of the first rear trailing arm and the second rear trailing arm at a different location than the first mechanism such that the second mechanism provides a completely separate and distinct load path, which links the rear trailing arms, from the first mechanism. - View Dependent Claims (24, 25)
