Patent ID: 7984915

Claim:
A vehicle suspension comprising: a hub for supporting a vehicle wheel; a trailing arm secured to the hub and also secured to the body of the vehicle; a first lateral arm located, relative to the vehicle, rearward of the rotational axis of the wheel, said first lateral arm being secured to the hub and also secured to the vehicle body and being generally transverse to the longitudinal axis of the vehicle; a second lateral arm located, relative to the vehicle, upward of the rotational axis of the wheel and upward of the first lateral arm, said second lateral arm being secured to the hub and also secured to the vehicle body and being generally transverse to the longitudinal axis of the vehicle; a third lateral arm located, relative to the vehicle, forward of the rotational axis of the wheel, said third lateral arm being secured to the trailing arm and also secured to the body of the vehicle and comprising a variable stiffness actuator; wherein the variable stiffness actuator includes a hydraulic circuit with an electronically controlled orifice where the open state of the orifice provides a fluid flow state in the actuator such that the third lateral arm is in a least stiff state, thus, affecting toe properties of the vehicle wheel.
