Liquid level detection system for a driveline component
The present disclosure relates to a detection system for detecting a liquid level in a rotating driveline component. The detection system may include a first sensor for detecting the liquid, a second sensor for detecting a rotational position of the driveline component, and a receiver for determining the liquid level based on the first and second sensors.
1. A liquid level detection system for a rotatable driveline component of a vehicle, the system including:
a sensing device configured to transmit a signal during a rotation of the rotatable driveline component, wherein the signal includes a liquid value from a first sensor and a rotation value from an accelerometer of a second sensor, the first sensor and the second sensor being positioned within the interior region of the rotatable driveline component; and
a receiver configured to receive the signal and to determine the liquid level in the interior region of the rotatable driveline component based on the liquid value and a rotational position of the rotatable driveline component based on the rotation value.
2. The system of claim 1 , wherein the receiver is operative to detect a complete rotation of the rotatable driveline component based on the rotation value and to determine the liquid level based on a plurality of readings from the first sensor taken during the complete rotation of the rotatable driveline component.
3. The system of claim 2 , wherein the receiver is operative to determine a portion of the complete rotation of the rotatable driveline component that the first sensor detects the liquid and to determine the liquid level based on the portion.
4. The system of claim 1 , wherein the receiver is operative to generate a warning signal upon the liquid level reaching a threshold level.
5. The system of claim 1 , wherein the sensing device includes an antenna operative to transmit the signal wirelessly to the receiver.
6. The system of claim 5 , wherein the antenna extends outside of the rotatable driveline component.
7. The system of claim 1 , wherein the sensing device is coupled to a wall of the rotatable driveline component, and the wall forms the interior region of the rotatable driveline component.
8. The system of claim 7 , wherein the sensing device includes a threaded plug having a hollow portion for receiving sensor components, and the wall of the rotatable driveline component includes a threaded aperture sized to receive the threaded plug to couple the sensing device to the rotatable driveline component.
9. The system of claim 1 , wherein the receiver is mounted to the vehicle remotely from the sensing device and is coupled to a communication network of the vehicle.
10. The system of claim 1 , wherein the rotatable driveline component includes a final drive coupled to a traction device of the vehicle, and the sensing device is operative to detect oil in the interior region of the final drive.
