Active vehicle suspension system
First Claim
Patent Images
1. An active suspension system for a vehicle comprising:
- a linear electromagnetic actuator comprising a stator and an armature that is movable relative to the stator, the stator being substantially rigidly attached to a frame of the vehicle; and
a control rod having a first end that is attached to the armature and having a second end that is attached to a wheel of the vehicle such that a movement of the armature causes the wheel of the vehicle to move relative to the frame of the vehicle;
wherein the linear electromagnetic actuator is substantially mechanically decoupled from a lateral motion of the wheel of the vehicle.

Abstract
An active suspension system for a vehicle includes an active suspension element that is substantially rigidly attached to a frame of the vehicle such that a motion of an armature of the active suspension element is mechanically decoupled from a lateral motion of a wheel of the vehicle. A control rod is attached between the active suspension element and the wheel of the vehicle.

14. An active suspension system for a vehicle comprising:
-
a linear electromagnetic actuator comprising a stator and an armature that is movable relative to the stator, the stator being substantially rigidly attached to a frame of the vehicle; and a control rod having a first end that is attached to the armature and having a second end that is attached to a wheel of the vehicle such that a movement of the armature causes the wheel of the vehicle to move relative to the frame of the vehicle; wherein the control rod comprises a bent portion.

15. A linear electromagnetic actuator for an active suspension system of a vehicle, the actuator comprising:
-
a stator; an armature that is magnetically coupled to the stator; a first bearing that is mechanically coupled to the armature, the first bearing maintaining an air gap between the armature and the stator; and a second bearing that is mechanically coupled to the stator and substantially mechanically decoupled from the armature, the second bearing absorbing suspension related bending loads, thereby minimizing the suspension related bending loads on the armature. - View Dependent Claims (16)
