Wear indicating friction disc
First Claim
Patent Images
1. A wear indicating friction disc assembly, comprising:
- a friction disc;
a first wear indicating element that is positioned within a portion of the friction disc that is engageable with an opposing friction member to transmit torque between the friction disc assembly and the opposing friction member, a height of the wear indicating element being set so as to engage the opposing friction member at a predetermined wear level of the friction disc assembly and thereby emit a first detectable vibratory signal upon sliding engagement with the opposing friction member; and
a second wear indicating element that is positioned within a portion of the friction disc that is engageable with the opposing friction member, a height of the wear indicating element being set so as to engage the opposing friction member at a second further predetermined wear level of the friction disc assembly and thereby emit a second detectable vibratory signal upon sliding engagement with the opposing friction member.

Abstract
A wear indicating friction disc assembly includes at least two friction discs and may include a plurality of clamping assemblies positioned around a circumference of the friction discs to clamp at least two of the friction discs together. At least one of the clamping assemblies may include a wear indicating washer with a wear indicating portion extending into a portion of one at least one of the friction discs. A height of the wear indicating portion is set to engage the opposing friction member at a predetermined wear level of the friction disc assembly and to emit a detectable signal upon sliding engagement with the opposing friction member.

15. A clutch, comprising:
-
a plurality of friction disc assemblies in axial alignment and engageable with one another to transmit torque;
each friction disc assembly comprising;a friction disc; at least one wear indicating element that is positioned within a portion of the friction disc that is engageable with an opposing friction disc assembly to transmit torque between the friction disc assembly and the opposing friction disc assembly, a height of the wear indicating portion being set so as to engage the opposing friction disc assembly at a predetermined wear level of the friction disc assembly and to emit a detectable vibratory signal upon sliding engagement with the opposing friction disc assembly; wherein the at least one wear indicating element for each friction disc assembly is constructed and arranged to emit a predetermined unique detectable vibratory signal upon sliding engagement with the opposing friction disc assembly so that the specific friction disc assembly in the clutch exhibiting wear can be identified. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
