Abstract

A torque converter is provided, comprising: an impeller (33) having an impeller housing having a first surface; an axially displaceable turbine-piston (36), the turbine-piston (36) is hydraulically drivable by the impeller and includes a turbine-piston housing and a turbine-piston flange having a second surface; and a clutch plate (80) interposed between the first and second surfaces and opposite to At least one of the first and second surfaces is axially displaceable. The turbine-piston is axially movable relative to the impeller to move a second surface of the turbine-piston flange toward and away from the first surface to position the torque converter in lockup mode and a disengaged mode in which the first and second surfaces and the clutch plate surface frictionally interlock with each other such that the impeller is mechanically locked to the turbine-piston and relative to the The turbine-piston is non-rotatable.

Description

technical field [0001] This invention relates generally to torque converters and hydrodynamic torque couplings, and more particularly, to torque converters and hydrodynamic torque couplings including turbine-piston lock-up clutches for mechanical Connect the drive shaft and the driven shaft ground. Background technique [0002] Typically, vehicles with automatic transmissions are equipped with a hydrodynamic torque coupling for fluidly coupling the drive shaft of the engine to the driven shaft of the transmission. Lock-up clutches are known for mechanically coupling a drive shaft and a driven shaft under certain operating conditions. Lock-up clutches and their operation are described, for example, in US Patent 8,276,723 and US Patent 7,191,879. [0003] While hydrodynamic torque couplings with lock-up clutches have proven useful for vehicle driveline applications and conditions, improvements are possible that could enhance their performance and cost. [0004] As taught he...
