Abstract

An exemplary energy delivery system includes a housing. The housing includes a linear motor including a translational member and an electromagnetic field generating member. Energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor. The housing further includes a first cylinder including a first chamber and a movable first piston and a second cylinder including a second chamber and a movable second piston. The first and second cylinders are coupled in-line with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction opposite the first direction.

First claim

What is claimed is:

1. An energy delivery system, comprising:
a housing, the housing including
a linear motor including a translational member and an electromagnetic field generating member, wherein energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor;
a first hydraulic cylinder including a first chamber and a movable first piston, the first chamber enclosing a hydraulic fluid;
a second hydraulic cylinder including a second chamber and a movable second piston, the second chamber enclosing a hydraulic fluid; and
a controller in communication with the linear motor;

wherein the first and second hydraulic cylinders are coupled with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction such that the first and second pistons act on the hydraulic fluid enclosed within the first and second hydraulic cylinders to change an amount of hydraulic fluid contained in each of the first and second hydraulic cylinders and the controller generates a control signal indicative of a position adjustment of the translational member such that the position adjustment adjusts a suspension dynamics setting of a vehicle.

2. The energy delivery system of claim 1 , wherein the first hydraulic cylinder is coupled to a first suspension component of a vehicle and the second hydraulic cylinder is coupled to a second suspension component of a vehicle.

3. The energy delivery system of claim 1 , wherein the first and second pistons are integral with the translational member of the linear motor.

4. The energy delivery system of claim 3 , wherein the second direction is opposite the first direction such that a volume of the first chamber increases when a volume of the second chamber decreases.

5. An automotive vehicle, comprising:
a suspension system including an adjustable suspension component;
an energy delivery system coupled to the adjustable suspension component, the energy delivery system comprising
a housing, the housing including
a linear motor including a translational member and an electromagnetic field generating member, wherein energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor;
a first cylinder including a first chamber and a movable first piston; and
a second cylinder including a second chamber and a movable second piston; and

a controller in electronic communication with the energy delivery system;
wherein the first and second cylinders are coupled in-line with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction such that the adjustable suspension component is adjusted from a first position to a second position.

6. The automotive vehicle of claim 5 , wherein the first chamber encloses a hydraulic fluid and the second chamber encloses a compressible member.

7. The automotive vehicle of claim 6 , wherein the compressible member is a spring coupled on one end to the second piston.

8. The automotive vehicle of claim 5 , wherein each of the first and second chambers encloses a hydraulic fluid.

9. The automotive vehicle of claim 5 , wherein the controller is in electronic communication with the linear motor and transmits a control signal to the linear motor to adjust a position of the translational member.

10. The automotive vehicle of claim 9 , wherein the control signal indicates a change in a selective energization of the electromagnetic field generating member.

11. An energy delivery system, comprising:
a housing, the housing including
a linear motor including a translational member and an electromagnetic field generating member, wherein energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor;
a first cylinder including a first chamber and a movable first piston, the first chamber enclosing a hydraulic fluid; and
a second cylinder including a second chamber and a movable second piston;

wherein the first cylinder is coupled to a first suspension component of a vehicle and the second cylinder is coupled to a second suspension component of the vehicle and the first and second cylinders are coupled with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction such that the first and second pistons act on the hydraulic fluid enclosed within the first cylinder to change an amount of hydraulic fluid contained in the first cylinder.

12. The energy delivery system of claim 11 , wherein the first and second pistons are integral with the translational member of the linear motor.

13. The energy delivery system of claim 12 , wherein the second direction is opposite the first direction such that a volume of the first chamber increases when a volume of the second chamber decreases.

14. The energy delivery system of claim 11 , wherein the first chamber encloses the hydraulic fluid and the second chamber encloses a compressible member.

15. The energy delivery system of claim 14 , wherein the compressible member is a spring coupled on one end to the second piston.

16. The energy delivery system of claim 11 , wherein the energy delivery system includes a controller.

17. The energy delivery system of claim 16 , wherein the controller generates a control signal indicative of an adjustment of a position of the translational member such that the position adjustment adjusts a suspension dynamics setting of a vehicle.
