Abstract
A single sided friction assembly is provided in which an annular ring of friction material is provided on only one side of a relatively heat conductive metallic core plate, with the rings facing the same direction, and the ring of friction material engaging the rear bare metal side of an adjacent disk. An actuator is provided to bring the assembly into frictional engagement. Modifications are made at one and preferably both ends of the assembly to accommodate thermal deformations of the disks.
Claims12
A friction assembly comprising a plurality of friction disks slidably mounted along a common axis with alternating adjacent disks being frictionally reactive, means for bringing said disks into frictional engagement, each friction disk comprising a metal core plate having a central opening and an annular ring of friction material secured to said plate only on one side thereof, said friction material rings facing in the same axial direction, a first outermost disk in said assembly having its bare core plate facing outwardly, a metal surface statically engageable with the bare metal core of said first disk, said first disk remaining cool relative to other friction disks upon engagement, with said other disks undergoing thermoelastic deformation relative to said first disk and causing uneven contact pressure between disks, and means for allowing said first disk to conform with the other disks during engagement.
A friction disk assembly, said assembly comprising a plurality of axially aligned friction disks, each of said friction disks comprising a metal disk and a ring of friction material secured to only one side of the metal disks with the ring of friction material of each disk facing in the same axial direction, and a bare metal surface on the other side of the disks, first and second end surfaces disposed at the ends of the assembly, one of said end surfaces being axially movable to bring the rings of friction material on each disk into frictional engagement with the bare metal surface of an adjacent disk, with alternating disks being rotable relative to adjacent disks to transfer energy upon engagement, a first and second disk in said series, the bare metal surface of said first disk not being engaged by an adjacent disk and being statically engaged by a metal surface and remaining cool relative to said second disk, which is thermally deformed upon engagement, and means associated with said first disk for allowing said first disk to conform to the thermally distorted second disk.
