Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
182 words
An annular friction member for a brake or clutch comprising a ring which has lugs on one peripheral edge for effecting torquetransmitting engagement with related brake or clutch structure and a series of individual arcuately shaped facing plates supported by and on opposite sides of such ring, and segments of nonwearing heat-absorbing material between the plates and separate from them; the resulting assembly being characterized in that: a. said facing plates have lugs on one edge registering with and fastened to the torque-transmitting lugs on said ring; and b. said facing plates have portions extending away from said lugs generally in the plane of said ring which portions collectively define two annular opposing friction faces of said friction member; and c. said facing plates are staggered on opposite sides of said ring so that each facing plate arcuately overlaps the adjoining portions of two corresponding facing plates on the opposite side of the ring; and d. each facing plate is connected to the two overlapped portions of its opposing facing plates by two fasteners which extend through said segments of heat-absorbing materials.
Claim 2
Dependent Claim
182 words
An annular friction member for a brake or clutch comprising a ring which has lugs on one peripheral edge for effecting torquetransmitting engagement with related brake or clutch structure and a series of individual arcuately shaped facing plates supported by and on opposite sides of such ring, and segments of nonwearing heat-absorbing material between the plates and separate from them; the resulting assembly being characterized in that: a. said facing plates have lugs on one edge registering with and fastened to the torque-transmitting lugs on said ring; and b. said facing plates have portions extending away from said lugs generally in the plane of said ring which portions collectively define two annular opposing friction faces of said friction member; and c. said facing plates are staggered on opposite sides of said ring so that each facing plate arcuately overlaps the adjoining portions of two corresponding facing plates on the opposite side of the ring; and d. each facing plate is connected to the two overlapped portions of its opposing facing plates by two fasteners which extend through said segments of heat-absorbing materials.
Claim 3
Dependent Claim
35 words
An annular friction member according to claim 1 in which said arcuately shaped facing plates are all of identical size and shape so that they can be used interchangeably on opposite sides of said ring.
Claim 4
Dependent Claim
36 words
An annular friction member according to claim 1 in which said segments of heat-absorbing material are all of identical size and shape but proportioned so that each arcuate facing plate axially abuts tWo of said segments.
