Abstract:
A torque transmission device comprising:a torque tube having an inner diameter surface;a plurality of stator type friction discs mounted on the torque tube;an axle which extends coaxially relative to and within the torque tube for rotatably supporting a rotatable member which has associated therewith a plurality of rotor type friction discs arranged with said rotor discs each interposed between a successive pair of stator discs in a disc assembly which is axially compressible for torque transmission between the torque tube and the rotatable member;an annular spacer member having an outer diameter surface which extends radially between the axle and torque tube to provide radial support between the torque tube and axle, the outer diameter surface of said annular spacer member being in frictional engagement with the inner diameter surface of said torque tube;axially spaced abutment surfaces which axially locate the spacer member; andspring means between at least one of said abutment surfaces and a confronting surface of the spacer member to provide an axial force resiliently to load the confronting surfaces of the spacer member and the abutments surfaces.
