Problems solved by technology

However, the higher spring rate renders the damper ineffective for two-cylinder models
Namely, the shock absorber is too stiff in two-cylinder mode due to the higher spring rate, some undesired vibrations go through the shock absorber

Abstract

A torque converter is disclosed and includes a cover for receiving torque; a pump non-rotatably connected to the cover; a turbine including a turbine shell; a turbine clutch including a portion of the turbine shell; a first torsional vibration damper including a first input plate non-rotatably connected to the turbine shell, a cover plate, an output flange arranged to non-rotatably connect to an input shaft for a transmission, and a plurality of springs, each spring in the plurality of springs engaged with the first input plate, the cover plate, or the output flange; a second torsional vibration damper including a second input plate, an output plate arranged to non-rotatably connect to the input shaft, and a spring engaged with the second input plate and the output plate; and a lock-up clutch including an axially displaceable piston plate arranged to non-rotatably connect the cover and the second input plate.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application 61 / 925,913, filed January 10, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a torque converter having parallel torsional dampers and associated clutches. Torque is transmitted through individual or parallel shock absorbers via associated clutches. The torque converter includes three fluid circuits arranged to enable independent operation of associated clutches. Background technique [0004] It is known to use a single torsional damper or a series of torsional dampers in a torque converter. The foregoing configuration provides a torque path from the torque converter's cover through the damping device to the output of the torque converter. Typically, the shock absorber is tuned according to the expected torque load on the shock absorber. For exam...
