A clutch device includes an input rotor, a first clutch, a second clutch, a first drive mechanism and a second drive mechanism. A first clutch is disposed switchably between a first transmitting state of transmitting power and a first blocking state of blocking power transmission. A second clutch is disposed switchably between a second transmitting state of transmitting power and a second blocking state of blocking power transmission. The first drive mechanism includes a first drive support member and the second drive mechanism includes a second drive support member. A drive clearance is configured to be produced axially between the first drive support member and the second drive support member in the first blocking state and the second blocking state. The drive clearance is less than a sum of the first stroke and the second stroke.

Clutch device

A clutch device includes an input rotor, a rotation support mechanism, a first pressure plate, a second pressure plate, a first clutch disc assembly and a second clutch disc assembly. The input rotor includes a first disc portion and a second disc portion disposed away from the first disc portion at a predetermined space. The rotation support mechanism supports the input rotor for allowing the input rotor to be rotated with respect to a first input shaft and a second input shaft.

A clutch device includes a first clutch, a second clutch, a diaphragm spring and an intermediate spring. The diaphragm spring transmits a pressing force to the first clutch and the second clutch. The intermediate spring applies a coupling maintaining force to the first clutch and the second clutch so that minimally power transmitted states of the first clutch and the second clutch are maintained while a pressing force is not being applied to the first clutch and the second clutch.

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 rotor disposed in a fluid retarder which includes a annular shell having a semicircular cross section and a plurality of blades, each blade being composed of a semicircular blade body and a rib bent from an arcuate edge of the blade body and fixed to an inside of the shell. The annular shell and the blades are composed of sheet metal. The blades are arranged at regular intervals in the circumferential direction of the shell and are welded into place. Because the annular shell and the blades are composed of sheet metal and are brazed together, the cost of manufacturing the rotor can be reduced without reducing its performance.
