摘要： A rolling-element clutch assembly including a first race member, a second race member and a plurality of rolling elements. The first race member defines a first race surface having a first ratchet surface portion. The second race member defines a second race surface having a second ratchet surface portion. The first race surface and the second race surface define a raceway therebetween. A plurality of rolling elements are disposed in the raceway. The rolling elements provide rolling support between the first race member and the second race member when the first race member moves in a first direction relative to the second race member. At least one of the plurality of rolling elements engages the first and second ratchet surface portions when the first race member moves in a second direction relative to the second race member. The engagement of the rolling element with the first and second ratchet surfaces impedes relative motion between the first race member and the second race member, thereby providing load transmission capability. The profile of each sawtooth incline may be formed from one or more flat planes. A rolling element separator may be provided, the separator allowing the rolling elements to freely roll when the first race member moves in a first direction relative to the second race member and to freely pivot into engagement with or disengagement from the ratchet surfaces when the first race member moves in a second direction relative to the second race member.

摘要： The present invention is a planar one-way clutch comprising a first and second plate rotatable about a common axis. The first plate is the driving plate. The second plate is the driven plate. The coupling surfaces of each plate define at least one recess. The recess in the first plate includes a strut receiving portion and a spring receiving portion. At least one strut, pivotable between a first and second position is received in the strut receiving portion of the first plate. At least one spring, having a base and an arm, is received within the spring receiving portion of the first plate. The arm extends from the base and engages the pivotable strut applying a controlled spring force to urge the strut towards the driven plate. The base portion of the spring is shaped to prevent at least circumferential movement of the spring.
