Abstract
A device for detecting undesirable vibrations in a vehicle drive line utilizes a sensor that communicates with a controller to indicate undesirable vibrations in a drive line component. In one example, a temperature sensor is placed in a central portion of a universal joint. The temperature sensor preferably is supported within a single housing along with a transmitter that is responsive to the temperature sensor to transmit a signal to a remotely located receiver without using a hardwire connection between the transmitter and receiver. Packaging the temperature sensor, transmitter and a power source within a single housing provides the ability to seal off or close a series of lubrication channels that extend through the universal joint. In another example, a contact-based sensor provides a signal whenever a vibration of a drive line component occurs. The contact-based sensor signal preferably is processed to monitor the number of vibrations over time and a vehicle operator is provided with an indication of the level of vibrations as desired.
