Abstract

A shock absorber system can includes a shock tube and a piston slidably mated to an end of the shock tube. The system can include a first mount on the piston for attaching to a first point on a motor vehicle. A second mount can be positioned on the shock tube near an end of the shock tube opposite the piston. The second mount can be positioned offset from an axial centerline of the shock tube. In some cases, the system can include a stabilizing device connected to the second mount. The system can include a heat sink reservoir. The heat sink reservoir can be connected to the shock tube via a valved fluid connection.

Claims (34)

1. A shock absorber system comprising:

a shock tube having a first end, a second end, a central axis extending through the first and second ends, and an outer wall extending between the first and second ends of the shock tube;

a piston rod extending at least partially into the shock tube through the second end of the shock tube, the piston rod having a first end positioned within the shock tube and a second end positioned outside of the shock tube, the piston having a longitudinal axis parallel to the central axis of the shock tube and extending through the first and second ends of the piston rod, the second end of the piston rod configured to connect to a first mounting point on a vehicle;

a tube mount offset from the central axis of the shock tube and connected to the outer wall of the shock tube between the first and second ends of the shock tube, the tube mount configured to connect to a second mounting point on a vehicle;

a stabilizing device connected to the tube mount and comprising:

a first arm connected to the tube mount and extending away from the tube mount in a first direction; and

a second arm connected to the first arm at a first connection point and to the outer wall of the shock tube at a second connection point, the second arm having a fixed length;

wherein the second arm is configured to maintain a fixed distance between the first connection point and the second connection point to inhibit or prevent movement of the shock tube in a direction perpendicular to a line perpendicular to the central axis of the shock tube and passing through the central axis of the shock tube and though the tube mount.

2. The system of claim 1 , wherein a length of the first arm is adjustable.

3. The system of claim 1 , wherein the piston rod is configured to reciprocate over a stroke length, wherein the stroke length is at least 70% of a length of the shock tube.

4. The system of claim 1 , wherein the tube mount is positioned at a vertical distance from the second end of the shock tube, and wherein the vertical distance is between about ⅗ and 19/20 of the length of the shock tube.

5. A shock absorber system comprising:

a shock tube having a first end, a second end, a central axis extending through the first end and the second end of the shock tube, and a tube volume;

a piston rod having a first end and a second end and slidably connected to the second end of the shock tube, the first end and second end of the piston rod lying on the central axis of the shock tube;

a piston head connected to the first end of the piston rod and positioned within the tube volume;

a piston mount connected to the second end of the piston rod and lying on the central axis of the shock tube, the piston mount configured to connect to a first position on a motor vehicle;

a tube mount connected to an outer sidewall of the shock tube and positioned offset from the central axis of the shock tube, the tube mount configured to connect to a second position on the motor vehicle; and

a stabilization device connected to the tube mount and configured to reduce movement between the tube mount and the second position of the motor vehicle when the tube mount is connected to the second position of the motor vehicle,

wherein the stabilization device comprises a first arm connected to the tube mount and a second arm connected to the first arm and to the shock tube.

6. The system of claim 5 , wherein the tube mount is positioned between the first and second ends of the shock tube.

7. The system of claim 5 , comprising a rod guide positioned at least partially within the tube volume, the rod guide configured to slidably engage the piston rod and to inhibit misalignment of the piston rod with respect to the central axis of the shock tube.

8. The system of claim 5 , wherein the first arm extends along an axis perpendicular to the central axis of the shock tube and perpendicular to a line passing through the central axis of the shock tube and a center of the tube mount.

9. The system of claim 8 , wherein the second arm extends along an axis parallel to the line passing through the central axis of the shock tube and the center of the tube mount.

10. The system of claim 9 , wherein the axis of extent of the first arm is substantially perpendicular to the axis of extent of the second arm.

11. The system of claim 10 , wherein the axis of extent of the first arm is substantially perpendicular to the line passing through the central axis of the shock tube and the center of the tube mount.

12. The system of claim 8 , wherein the axis of extent of the first arm is substantially perpendicular to the line passing through the central axis of the shock tube and the center of the tube mount.

13. The system of claim 5 , wherein a length of the first arm is adjustable.

14. The system of claim 5 , wherein a length of the second arm is adjustable.

15. The system of claim 5 , comprising an end cap on the first end of the shock tube, wherein the tube mount is not connected to the end cap.

16. The system of claim 5 , wherein the piston head is configured to reciprocate over a stroke length, wherein the stroke length extends over at least 70% of a length of the shock tube.

17. The system of claim 16 , wherein the stroke length extends over at least 80% of the length of the shock tube.

18. The system of claim 5 , wherein the tube mount is positioned at a vertical distance from the second end of the shock tube, and wherein the vertical distance is less than a length of the shock tube between the first and second ends of the shock tube.

19. The system of claim 18 , wherein the vertical distance is between about ⅗ and 19/20 of the length of the shock tube.

20. The system of claim 5 , further comprising one or more nuts positioned on at least one of the first arm, the second arm, the tube mount, or the shock tube to tighten or loosen corresponding connection points.
