Vibration sensing and diagnostic system for transmission assembly
First Claim
1. A combined transmission and monitoring system for indicating an operating condition of the transmission comprising:
- a transmission including a case, an input shaft extending within said case, an output shaft extending within said case, and a plurality of components supported on said case for connecting said output shaft for rotation at a predetermined speed relative to said input shaft;
a sensor responsive to vibration of a portion of said transmission 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 transmission when said signal from said sensor deviates from said predetermined signal characteristic by more than a predetermined amount.

Abstract
A combined transmission assembly and monitoring system for indicating the operating condition of the transmission assembly includes a transmission assembly having an input shaft, an output shaft, and a plurality of components for connecting the output shaft for rotation at a predetermined speed relative to the input shaft, a sensor attached to a portion of the transmission assembly, the sensor being responsive to vibration of the portion of the transmission assembly for generating signals indicative of the sensed vibration, and a controller for receiving the signals from the sensor and generating an indication of the operating condition of the transmission assembly based on the vibration of the portion of the transmission assembly. Preferably the sensor is adapted to detect both the frequency and magnitude of vibration of the transmission assembly and to generate signals indicative of the sensed frequency and magnitude of vibration.

11. A combined transmission and monitoring system for indicating an operating condition of the transmission comprising:
-
a transmission including a case, an input shaft extending within said case, an output shaft extending within said case, a plurality of gears supported on said case for connecting said output shaft for rotation at a plurality of predetermined speed relative to said input shaft, a shift lever for selecting a desired one of said plurality of gear ratios, and a shift tower assembly mounted on said case for supporting said shift lever; a sensor mounted on said shift tower assembly and responsive to frequency and magnitude of mechanical vibration of said transmission 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 the operating condition of said transmission when said signal from said sensor deviates from said predetermined signal characteristic by more than a predetermined mount. - View Dependent Claims (12, 13, 14, 15, 16, 17)
