Abstract

A suspension system of an associated vehicle. The suspension system comprises an outer reservoir tube extending along an axis between a first end and a second end and defining a chamber. A piston assembly is at least partially located in the chamber. The piston assembly includes a piston rod and a piston head. A solenoid assembly is connected to the piston rod. The solenoid assembly comprises a core including a core head and a core body. A spool extends about the core body and defines a space. A coil is wrapped around the spool within the space. An induction plate is at least partially located between the spool and the core head. As the input current is modulated the induction plate promotes the induction of eddy currents opposing the field induction attenuating the force ripples of the magnetic field buildup and decay.

First claim

What is claimed is:

1. A solenoid assembly for a suspension system of an associated vehicle, the solenoid assembly comprising:
a core including a core head and a core body, wherein the core head extends radially outwardly from the core body;
a spool extending about the core body and located in abutment with the core body and defining a space;
a coil wrapped around the spool within the space; and
an induction plate at least partially located between the spool and the core head, wherein the induction plate includes a top ring portion located between the spool and the core head and abutting the core body and the core head, wherein the top ring portion includes an inner diameter that is located radially inwardly from an inner diameter of a wrapping of the coil, and an outer diameter that is located radially outwardly from an outer diameter of the wrapping of the coil.

2. The solenoid assembly as set forth in claim 1 , wherein the induction plate includes a bridge portion extending from the top ring portion in hugging engagement around the core head.

3. The solenoid assembly as set forth in claim 2 , wherein the induction plate further includes a hook portion extending radially outwardly from the bridge portion.

4. The solenoid assembly as set forth in claim 3 , wherein a space is defined between the hook portion and the bridge portion and wherein an O-ring is located in the space.

5. The solenoid assembly as set forth in claim 1 , wherein a weld interface is located between and connects the induction plate and the core.

6. The solenoid assembly as set forth in claim 1 , wherein the induction plate is formed of a material having a conductivity of at least 1,100,000 Siemens/m.

7. The solenoid assembly as set forth in claim 1 , wherein the induction plate is formed of Copper.

8. The solenoid assembly as set forth in claim 1 , wherein the induction plate is formed of Aluminum.

9. The solenoid assembly as set forth in claim 1 , wherein the induction plate is formed of stainless steel.

10. The solenoid assembly as set forth in claim 9 , including a body extending about the spool, the core, and the induction plate, wherein the body includes a collar portion defining a collar channel for accommodating a provided cable to electrically connect to the coil.

11. A suspension system of an associated vehicle, the suspension system comprising:
an outer reservoir tube extending along an axis between a first end and a second end and defining a chamber;
a piston assembly at least partially located in the chamber, the piston assembly including a piston rod and a piston head;
a solenoid assembly connected to the piston rod, the solenoid assembly comprising:
a core including a core head and a core body;
a spool extending about the core body and defining a space;
a coil wrapped around the spool within the space; and
an induction plate at least partially located between the spool and the core head,
wherein the induction plate includes a top ring portion located between the spool and the core head, wherein the top ring portion includes an inner diameter that is located radially inwardly from an inner diameter of a wrapping of the coil, and an outer diameter that is located radially outwardly from an outer diameter of the wrapping of the coil.

12. The solenoid assembly as set forth in claim 11 , wherein the induction plate includes a bridge portion extending from the top ring portion in hugging engagement around the core head towards the piston head.

13. The solenoid assembly as set forth in claim 12 , wherein the induction plate further includes a hook portion extending radially outwardly from the bridge portion.

14. The solenoid assembly as set forth in claim 13 , wherein a space is defined between the hook portion and the bridge portion and wherein an O-ring is located in the space.

15. The solenoid assembly as set forth in claim 11 , wherein a weld interface is located between and connects the induction plate and the core.

16. The solenoid assembly as set forth in claim 11 , wherein the induction plate is formed of at least one of Copper, Aluminum, or stainless steel.

17. A solenoid assembly for a suspension system of an associated vehicle, the solenoid assembly comprising:
a core including a core head and a core body;
a spool extending about the core body and defining a space;
a coil wrapped around the spool within the space; and
an induction plate at least partially located between the spool and the core head, wherein a weld interface is located between and connects the induction plate and the core.

18. The solenoid assembly as set forth in claim 17 , wherein the induction plate is formed of at least one of Copper, Aluminum, or stainless steel.

19. The solenoid assembly as set forth in claim 17 , wherein the induction plate includes a top ring portion located between the spool and the core head.

20. The solenoid assembly as set forth in claim 19 , wherein the induction plate includes a bridge portion extending from the top plate portion in hugging engagement around the core head.
