Illuminating coating for an element of a suspension assembly
The suspension assembly may include a suspension element operably coupling a chassis to a wheel assembly of the vehicle, and a coating operably coupled to an exposed portion of the suspension element that is compressed or displaced responsive to a suspension event. The coating when powered may emit light to illuminate the suspension element and an area proximate to the suspension element.
1. A suspension assembly of a vehicle, wherein the suspension assembly comprises:
a suspension element operably coupling a chassis to a wheel assembly of the vehicle; and
a coating operably coupled to an exposed portion of the suspension element that is compressed or displaced responsive to a suspension event,
wherein the coating when powered emits light to illuminate the suspension element and an area proximate to the suspension element.
2. The suspension assembly of claim 1 , wherein the suspension element is a coil spring, a leaf spring, a pneumatic spring, a stabilizer bar, a torsion spring, control arm, steering hub, suspension sleeve, suspension bellows, suspension cover, or a suspension bushing.
3. The suspension assembly of claim 1 , wherein the light is emitted based on an electroluminescent property of the coating.
4. The suspension assembly of claim 1 , wherein the coating is powered by a wired connection to one or more onboard power sources of the vehicle.
5. The suspension assembly of claim 1 , wherein the coating is powered via a piezoelectric element.
6. The suspension assembly of claim 1 , wherein the coating is powered via a radio frequency (RF) power element.
7. The suspension assembly of claim 1 , wherein the suspension element further comprises integrated circuitry embedded within the coating.
8. The suspension assembly of claim 7 , wherein the integrated circuitry includes one or more electrical connections to other components of the vehicle, and
wherein the one or more electrical connections are disposed at a substantially stationary portion of the suspension element.
9. The suspension assembly of claim 7 , wherein the integrated circuitry is formed via conductive ink printing.
10. The suspension assembly of claim 7 , wherein the integrated circuitry further comprises a sensor,
wherein the sensor provides active suspension telemetry data in real-time to a control module of the vehicle.
11. The suspension assembly of claim 10 , wherein the sensor is a strain gauge.
12. The suspension assembly of claim 1 , wherein an intensity of the light varies responsive to the suspension event.
13. The suspension assembly of claim 12 , wherein the intensity of the light varies proportionally with the suspension event.
14. The suspension assembly of claim 13 , wherein the suspension event is an amount of displacement or compression of the suspension element.
15. The suspension assembly of claim 1 , wherein the suspension element is a spring,
wherein the coating adjusts a multi-rate spring characteristic of the spring, and
wherein the multi-rate spring characteristic is a change in spring rate as the spring is displaced.
16. The suspension assembly of claim 15 , wherein a thickness of the coating adjusts the multi-rate spring characteristic.
17. The suspension assembly of claim 1 , wherein the coating is an elastic coating.
18. The suspension assembly of claim 1 , wherein the coating provides corrosion resistance for the suspension element.
19. A suspension element for operably coupling a chassis to a wheel assembly of a vehicle, the suspension element comprising:
a first interface portion in contact with a chassis component;
a second interface portion in contact with a wheel assembly component;
a reaction portion disposed between the first interface portion and the second interface portion to be displaced or compressed responsive to a suspension event;
an exposed portion externally visible when the suspension event occurs; and
a coating operably coupled to the exposed portion of the suspension element that is displaced or compressed responsive to the suspension event,
wherein the coating when powered emits light to illuminate the suspension element and an area proximate to the suspension element.
20. The suspension element of claim 19 , wherein the reaction portion and the exposed portion at least partially overlap.
