In a clutch manufacturing method, inner peripheral portions of drum members, of two clutches are connected to a sleeve member, and a piston, a seal plate and a return spring are provided between the drum members, an insulator to apply electric isolation between the piston and the drum member or between the seal plate and another drum member is attached to either the piston or the seal plate. Then, the drum member, to which the electric isolation with the insulator is not applied, is connected to the sleeve member. Then, the piston, return sprig and seal plate are assembled to the sleeve member to which the drum member has been connected. Finally, the drum member, to which the electric isolation with the insulator has been applied, is connected to the sleeve member with electric welding.
A manufacturing method of a clutch for an automatic transmission which comprises two clutches provided on an input side of a transmission mechanism to conduct connection/disconnection between of an input shaft and the transmission mechanism, inner peripheral portions of respective drum members of which are connected to a sleeve member connected to the input shaft at different positions in an axial direction, a piston provided between the both drum members on an outer periphery side of the sleeve member, the piston forming an oil-pressure chamber of one of the clutches with the drum member of said one of the clutches, a seal plate provided between the drum member of the other of the clutches and said piston, the seal plate forming a centrifugal balance oil-pressure chamber of said one of the clutches, and a return spring provided between said piston and said seal plate to bias said piston toward the drum member of said one of the clutches in a state in which one end of thereof is received by the drum member of said other of the clutches via the seal plate, the manufacturing method comprising:
A manufacturing method of a clutch for an automatic transmission which comprises two clutches provided on an input side of a transmission mechanism to conduct connection/disconnection between of an input shaft and the transmission mechanism so as to be disposed side by side in a radial direction, inner peripheral portions of respective drum members of which are connected to a sleeve member connected to the input shaft at different positions in an axial direction, a piston provided between the both drum members on an outer periphery side of the sleeve member, the piston forming an oil-pressure chamber of an outer clutch of the clutches with the drum member of the outer clutch, a seal plate provided between the drum member of an inner clutch of the clutches and said piston, the seal plate forming a centrifugal balance oil-pressure chamber of the outer clutch, and a return spring provided between said piston and said seal plate to bias said piston toward the drum member of the outer clutch in a state in which one end of thereof is received by the drum member of the inner clutch via the seal plate, the manufacturing method comprising:
An automatic transmission, comprising:
An automatic transmission, comprising:
