Title:
FRICTION DISC APPARATUS AND RELATED TORQUE CONVERTER ASSEMBLIES FOR USE WITH VEHICLES
Document Type and Number:
WIPO Patent Application WO/2021/256708
Kind Code:
A1
Abstract:
Friction disc apparatus and related torque converter assemblies for use with vehicles are disclosed. A disclosed assembly includes a torsional vibration damper including a plate. The assembly also includes a clutch operatively coupled to the torsional vibration damper. The clutch includes a friction disc having a tab coupled to a distal portion of the friction disc and extending axially away from the distal portion. The clutch also includes a piston configured to urge the friction disc into engagement with a torque converter cover to transfer torque from the torque converter cover to the torsional vibration damper. The tab includes a first segment directly contacting a spring member or a spring seat of the torsional vibration damper and a second segment, between the first segment and the distal portion of the friction disc, configured to slide against a guide surface of the plate to provide radial guidance to the friction disc.
