Title: Torque converter disconnect and bypass clutch structure for automatic mechanical transmission

Abstract

This patent describes a torque converter and clutch structure for a drive system of the type comprising a torque converter drivingly interposed a prime mover and the input shaft of a mechanical change gear transmission. The torque converter has an impeller input member adapted to be driven by the prime mover and a turbine output member fluidly driven by the input member. The torque converter and clutch structure are characterized by: a connecting member fixed for rotation with the input shaft of the mechanical change gear transmission; a first friction clutch selectively engagable and disengagable to drivingly connect and disconnect, respectively, the output member to the connecting member; a second friction clutch selectively engagable and disengagable to drivingly connect and disconnect, respectively, the input member to the connecting member. The first friction clutch consists of at least one first friction member carried for rotation with the connecting member and the second friction clutch comprising at least one second friction member carried for rotation with the connecting member; the first friction clutch providing the sole driving connection between the output member and the input shaft with the second friction clutch in the disengaged condition; and means to independently engage and disengagemore » the first and second friction clutches.« less
