Abstract
Presented are engine disconnect clutches, methods for making/using such clutch devices, and vehicles with an engine that is coupled to/decoupled from a transmission and motor via a disconnect clutch. A vehicle includes a transmission with an input shaft connected with a transmission gearing arrangement, and an output shaft connecting the gearing arrangement with the vehicle's wheels. A torque converter pump housing drivingly connects to the vehicle's traction motor. A turbine is mounted inside the pump housing in fluid communication with an impeller. A turbine shaft connects the turbine to the transmission's input shaft. A clutch hub of a disconnect clutch drivingly connects to the vehicle's engine and selectively attaches to the pump housing. The disconnect clutch selectively connects the engine to the motor and transmission by drawing oil from the transmission's oil sump, through a turbine shaft channel and a pump housing port, and into a clutch hub cavity.
