Abstract

A replacement indicator for a shock absorber includes a pressure sensor which monitors pressure of operating fluid inside the shock absorber. The replacement indicator includes an indicative mechanism operatively coupled with the pressure sensor. The indicative mechanism includes an indicator component coupled to the shock absorber. The indicator component gets displaced relative to an outer surface of the shock absorber when the pressure of the operating fluid drops below a threshold pressure.

Claims (13)

1. A replacement indicator for a shock absorber comprising:

a pressure sensor configured to monitor pressure of operating fluid inside the shock absorber; and

an indicative mechanism operatively coupled with the pressure sensor, wherein the indicative mechanism includes an indicator component coupled to the shock absorber, wherein the indicator component gets displaced relative to an outer surface of the shock absorber when the pressure of the operating fluid drops below a threshold pressure.

2. The replacement indicator of claim 1 , wherein the indicator component getting displaced relative to the outer surface of the shock absorber indicates replacement requirement of the shock absorber.

3. The replacement indicator of claim 1 , wherein the threshold pressure is defined as a minimum operating pressure required for functioning of the shock absorber.

4. The replacement indicator of claim 1 , wherein the pressure sensor is mechanical pressure sensor.

5. The replacement indicator of claim 1 , wherein the indicator component getting displaced relative to the outer surface of the shock absorber indicates that the shock absorber should be inspected.

6. The replacement indicator of claim 1 , wherein the indicator component getting displaced relative to the outer surface of the shock absorber indicates that the shock absorber should be replaced.

7. The replacement indicator of claim 1 , wherein the operating fluid is a gas, and the pressure sensor monitors a gas pressure.

8. The replacement indicator of claim 1 , wherein the shock absorber has a head end and a rod end, and the pressure sensor is disposed towards the head end.

9. The replacement indicator of claim 8 , wherein the indicative mechanism is disposed towards the head end.

10. The replacement indicator of claim 1 , wherein the shock absorber has a head end and a rod end, and the pressure sensor is disposed towards the rod end.

11. The replacement indicator of claim 10 , wherein the indicative mechanism is disposed towards the rod end.
