20090054186 | Tensioner - A tensioner comprising a base, a pivot arm rotationally connected to the base, a pulley journalled to the pivot arm, a torsion spring engaged between the base and the pivot arm for biasing the pivot arm, a damping member non-rotatingly engaged with the base, a thrust plate rotationally moveable in conjunction with the pivot arm, and the torsion spring exerting an axial force directly upon the thrust plate and thereby upon the damping member, pressing the damping member into frictional engagement with the pivot arm and with the thrust plate. | 02-26-2009 |
20090075768 | Tensioner - A tensioner comprising a base, a pivot arm rotationally connected to the base, a pulley journalled to the pivot arm, a torsion spring engaged between the base and the pivot arm for biasing the pivot arm, a first damping member and a second damping member, each engaged with the base such that each cannot rotate with respect to the base but can move axially, a friction member connected to and rotationally moveable with the pivot arm, the friction member disposed between the first damping member and the second damping member, and the torsion spring exerting a normal force directly upon the first damping member, thereby pressing the first damping member and the second damping member into frictional engagement with the friction plate. | 03-19-2009 |
20090163312 | Tensioner - A tensioner comprising a base comprising a first portion, an arm comprising a second portion, the arm pivotally connected to the base, a pulley journalled to the arm, a resilient member compressively disposed between the first portion and the second portion, the resilient member comprising a gap within which the first portion and the second portion are disposed, and the resilient member comprising a bore, the bore engaging the arm. | 06-25-2009 |
20090239696 | Tensioner - A tensioner comprising a base, a pivot arm pivotally engaged with the base, a torsion spring engaged between the base and the pivot arm for biasing the pivot arm, a first damping member and a second damping member disposed between the pivot arm and the base, the first damping member wedgingly engagable between the pivot arm and the second damping member, and the second damping member frictionally engaged between the first damping member and the base. | 09-24-2009 |
20130157794 | CVT SPIDER LOCK - This disclosure generally includes description of a clutch for a continuous variable transmission (CVT), more particularly to the drive clutch of a CVT for immovably coupling a spider portion to a CVT shaft during reverse rotation or acceleration or deceleration of the CVT shaft. | 06-20-2013 |
