Abstract

A suspension component includes a gas spring. The gas spring includes a cylinder, a rod movable relative to the cylinder, and a sensor having a shaft extending through the cylinder to the rod. The sensor is configured to provide a signal indicative of a ride height of a vehicle.

Claims (32)

1 . A suspension component for a vehicle, the suspension component comprising:

a gas spring including:

a cylinder;

a rod movable relative to the cylinder; and

a sensor having a shaft extending through the cylinder to the rod, wherein the sensor is configured to provide a signal indicative of a ride height of the vehicle.

2 . The suspension component of claim 1 , wherein the sensor is a linear variable differential transformer.

3 . The suspension component of claim 1 , further comprising an accumulator coupled to the gas spring, the accumulator including a rigid exterior and a movable component internal to the rigid exterior.

4 . The suspension component of claim 3 , wherein the movable component separates an interior of the rigid exterior into a first portion and a second portion, wherein the first portion is in gaseous communication with the cylinder, and wherein the second portion contains a gas.

5 . The suspension component of claim 4 , wherein the accumulator includes a port configured to facilitate adjusting a pressure of the gas within the second portion.

6 . The suspension component of claim 3 , wherein the movable component is a bladder.

7 . The suspension component of claim 3 , wherein the accumulator is configured to facilitate providing a multi-stage spring rate for the gas spring.

8 . A suspension component for a vehicle, the suspension component comprising:

an accumulator configured to couple to a cylinder of a gas spring, the accumulator including:

a rigid exterior defining a first chamber; and

a bladder disposed within the first chamber, the bladder separating the first chamber into (a) a first accumulator portion configured to be in fluid communication with a second chamber of the cylinder and (b) a second accumulator portion;

a sensor configured to provide a signal indicative of a ride height of the vehicle based on a status of the gas spring.

9 . The suspension component of claim 8 , further comprising the gas spring.

10 . The suspension component of claim 8 , wherein the accumulator includes a valve configured to be positioned between the first accumulator portion of the first chamber and the second chamber.

11 . The suspension component of claim 8 , wherein the accumulator includes a port in fluid communication with the second accumulator portion of the first chamber.

12 . The suspension component of claim 8 , wherein the sensor is a linear variable differential transformer having a shaft configured to extend at least partially through the gas spring.

13 . The suspension component of claim 8 , wherein the accumulator facilitates providing a multi-stage spring rate for the gas spring.

14 . The suspension component of claim 13 , wherein the multi-stage spring rate is adjustable by increasing or decreasing an initial gas pressure in the bladder.

15 . A suspension component for a vehicle, the suspension component comprising:

an accumulator configured to couple to a cylinder of a gas spring; and

a sensor configured to provide a signal indicative of a ride height of the vehicle based on a status of the gas spring;

wherein the accumulator is configured to facilitate providing a multi-stage spring rate for the gas spring; and

wherein the multi-stage spring rate is adjustable by increasing or decreasing an initial gas pressure in the accumulator.

16 . The suspension component of claim 15 , further comprising the gas spring.

17 . The suspension component of claim 15 , wherein the accumulator includes:

a rigid exterior defining a chamber; and

a bladder disposed within the chamber, the bladder separating the chamber into (a) a first accumulator portion in fluid communication with the cylinder and (b) a second accumulator portion.

18 . The suspension component of claim 17 , wherein the accumulator includes a port in fluid communication with the second accumulator portion of the chamber, the port configured to facilitate introducing or removing gas from the second accumulator portion.
