An actuator for driving a release mechanism of a clutch includes a motor, an output member, a ball screw mechanism, a trapezoidal screw mechanism and a power transmission mechanism. The output member is coupled to the release mechanism, and is movable in an actuation direction of the release mechanism. The ball screw mechanism is configured to convert rotation of the motor in one direction into movement of the output member in a first axial direction. The trapezoidal screw mechanism has a self-lock function against a reverse driving force from the release mechanism, and is configured to convert rotation of the motor in the other direction into movement of the output member in a second axial direction. The power transmission mechanism is configured to selectively transmit rotation of the motor to the ball screw mechanism or the trapezoidal screw mechanism.

Clutch actuator

An impellerconfigures a fluid chamber and includes impeller bladesand an annular impeller hub. A turbineis disposed to face the impellerand includes turbine bladesand an annular turbine hubdisposed at an inner peripheral side of the turbine blades. A ball bearingis disposed between an inner peripheral surface of the impeller huband an outer peripheral surface of the turbine hub. A first stop ringthat engages with a first grooveand an engagement groovefixes the ball bearingwith respect to the impeller hubdue to the ball bearingand the impeller hubbeing brought into close proximity to each other in the axial direction. A second stop ringengaged with a second groovefixes the ball bearingand the turbine hub

Fluid coupling and method of manufacturing fluid coupling

A method of manufacturing a double wrap brake band having three bands, friction facings fastened to each band, and a connecting member connecting outside bands of the three bands with an intermediate band of such bands. A first bracket member is secured to both outside bands, and a second bracket member secured to the intermediate band. The three bands, the connecting member, and the first and second bracket members are all made of sheet metal. Edges, receiving a piston, or an anchor, at their backsides, are integrally formed on the first and second bracket members. The connecting member and the first and second bracket members are secured to the three bands by rivets. The second bracket member is provided with wing-shaped reinforcing members which stretch integrally from both sides of a portion secured to the intermediate band at the backside of the edge toward a lateral direction of both outside bands to cover both outside bands, and extend integrally in a circumferential direction to both front side protions of the edge.
