Vibration sensing and diagnostic system for vehicle drive train components
First Claim
1. A combined drive train assembly and monitoring system comprising:
- a drive train assembly including a power distribution device for distributing rotative power within the drive train;
a sensor responsive to vibration of said power distribution device for generating a signal which is representative thereof; and
a controller responsive to said signal from said sensor for comparing said signal from said sensor with a predetermined signal characteristic and for generating an indication of an operating condition of said power distribution device when said signal from said sensor deviates from said predetermined signal characteristic by more than a predetermined amount.

Abstract
A drive train assembly and monitoring system for indicating the operating condition of the drive train assembly includes a drive train assembly having a power distribution device for distributing rotative power within the drive train. A sensor is attached to a portion of the drive train assembly, the sensor being responsive to the vibration of the portion or component of the drive train assembly for generating signals indicative of the sensed vibration. A controller receives the signals from the sensor and generates an indication of the operating condition of the drive train assembly based on the vibration of the portion of the drive train assembly. Preferably the sensor is adapted to detect both the frequency and magnitude of vibration of the drive train assembly and to generate signals indicative of the sensed frequency and magnitude of vibration.
