Abstract: A selectable one-way clutch includes pawl members provided to a held plate rotatably via a spindle; a selector plate rotatable between a lock position where the pawl members are protrudable from the held plate and a release position where the pawl members are kept in a state the pawl members are housed in the held plate side by contacting a non-formation portion where no aperture is formed; and a device which restricts an operation of the pawl members by using volume change of material whose volume changes according to temperature change, so that the pawl members are more restricted to protrude from the first plate as an environmental temperature gets lower.

Abstract: An electromagnetic clutch includes a wrap spring being wound around to be in a pressure bonding state relative to an outer peripheral surface of a tubular portion of a driving-side rotation member. A first end of the wrap spring connects to a driving arm of a driving member, which connects to a driven-side rotation member. A second end of the wrap spring connects to a rim portion of an operating member formed in a disc form. The operating member is rotatable relative to the driven-side rotation member about the rotation axis as the center and movable along the rotation axis. After a rotation of the operating member is restrained, the driving member is restrained from rotation, which operates the wrap spring to twist and cancels the pressure boding state of the wrap spring relative to the driving-side rotation member, which in turn provides a power cutoff state.

The electromagnet is operable to attract the fixing pin to separate the fixing pin from the tire when the electromagnet is powered on. The elastic member is disposed between the electromagnet and the fixing ping, and pushes the fixing pin into the fixing hole when the electromagnet is powered off.

Abstract: A coil spring (50) for use in an overrunning spring clutch assembly having a central arbor (16) for centering and supporting the coil spring (50) in an overrunning operating mode. The coil spring (50) includes teaser coils (52) disposed at each end thereof, central coils (54) disposed intermediate the teaser coils (52), and transition coils (56) disposed between and adjoining the teaser coils (52) and the central coils (54). The coil spring (50) is characterized by each of the transition coils (56) having an interface surface (56.sub.IS) being substantially complementary to a corresponding external bearing surface (16.sub.ES) defined by the central arbor (16) of the spring clutch assembly. Such substantially complementary relationship limits the radial deflection of the transition coils (56) in the overrunning operating mode, thereby reducing vibratory bending stresses in the coil spring (50).

Abstract: The invention relates to a locking device 4 for a freewheeling unit 1 of a non-directly driven axle of a motor vehicle driven by a directly driven axle. To lock the freewheeling unit 1 there is provided a first drive element 2 with a number of circumferentially distributed apertures 15 holding radially displaceable locking elements 16. The locking elements, for the purpose of establishing a non-rotating connection between the first drive element 2 and the second drive element 3, may partially enter recesses 17 of the second drive element 3 corresponding to the apertures. Radial displacement of the locking elements 16 is achieved by a spring loaded axially movable control element 10. Displacement of the control element 10 is achieved by radially outward displacement of centrifugal masses 20.

Abstract: A temperature responsive clutch has a first arcuate inward facing clutch member, which can be a housing, secured to a rotating shaft. A second arcuate outward facing clutch member is mounted on the shaft radially inward from the first member and rotates independent of the first member. At least a portion of the second clutch member is adapted to move into and out of engagement with the first member. In the engaged position, the first and second members rotate in unison to rotate a fan attached to the second member. A temperature responsive device, such as a wax pill motor, is located so air passes thereover. The temperature responsive device will move a portion of one of said members radially into engagement with the other member when the temperature of the passing air signals that additional cooling is needed.
