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.

First claim

What is claimed is:

1 . A rear suspension system for a laterally tiltable, multitrack vehicle, comprising:
first and second trailing arms; and first and second balancer systems acting between the first and second trailing arms, wherein the first balancer system creates a torque to influence a leaning angle of the vehicle when the suspension system is in use, and wherein the second balancer system suppresses a resonant vertical motion of the vehicle when the suspension system is in use.

2 . The suspension system of claim 1 , wherein the first and second trailing arms are parallel to one another.

3 . The suspension system of claim 1 , wherein, when the suspension system is in use, the first and second trailing arms are each configured to extend between a rear wheel of the vehicle and a frame rail of the vehicle.

4 . The suspension system of claim 1 , wherein the first balancer system comprises a first balancer control arm, a first hinged control arm connected to the first balancer control arm, and an actuator attached to the first hinged control arm.

5 . The suspension system of claim 1 , wherein the second balancer system comprises a second balancer control arm and at least one spring/damper element.

6 . The suspension system of claim 5 , wherein the at least one spring/damper element comprises a shock absorber and a coil spring.

7 . The suspension system of claim 5 , wherein the second balancer system comprises two vertical spring/damper elements connected to opposite ends of the second balancer control arm.

8 . The suspension system of claim 5 , wherein the second balancer system further comprises a second hinged control arm connected to the second balancer control arm, and wherein the at least one spring/damper element is connected to the second hinged control arm.

9 . The suspension system of claim 1 , wherein the second balancer system comprises two link arms and a lateral spring/damper element operating between the link arms.

10 . The suspension system of claim 1 , wherein the second balancer system comprises a leaf spring.

11 . The suspension system of claim 1 , wherein each of the first and second trailing arms has about a 90 degree angle.

12 . The suspension system of claim 11 , wherein the first balancer system comprises an actuator, and wherein the first and second trailing arms are configured to reposition the actuator with respect to a body of the vehicle.

13 . The suspension system of claim 11 , wherein the second balancer system comprises a lateral spring/damper element, and wherein the first and second trailing arms are configured to reposition the spring/damper element with respect to a body of the vehicle.

14 . A rear suspension system for a laterally tiltable, multitrack vehicle, comprising:
first and second trailing arms, each trailing arm extending between a rear wheel of the vehicle and a frame rail of the vehicle; a first balancer system acting between 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 a second balancer system acting between the first and second trailing arms, the second balancer system being configured to suppress a resonant vertical motion of the body of the vehicle.

15 . The suspension system of claim 14 , wherein the first balancer system comprises a first balancer control arm, a first hinged control arm connected to the first balancer control arm, and an actuator attached to the first hinged control arm.

16 . The suspension system of claim 14 , wherein the second balancer system comprises a second balancer control arm and at least one spring/damper element.

17 . The suspension system of claim 14 , wherein the second balancer system comprises two link arms and a lateral spring/damper element operating between the link arms.

18 . The suspension system of claim 14 , wherein the second balancer control system comprises a leaf spring.

19 . The suspension system of claim 14 , wherein each of the first and second trailing arms has about a 90 degree angle.

20 . A method of stabilizing a tiltable, multitrack vehicle, the method comprising:
distributing a first load via a first balancer system during a roll motion of the vehicle; and distributing a second load via a second balancer system during a jounce/rebound motion of the vehicle, the second balancer system differing from the first balancer system, wherein distributing the first load influences a leaning angle of the vehicle, and wherein distributing the second load suppresses a resonant vertical motion of the vehicle.
