A drive assembly for a torque converter is provided. The drive assembly includes an axially movable turbine defining a piston of a lockup clutch; and a damper assembly including a first component including a plurality of first ramps and a second component including a plurality of second ramps, the first ramps configured for interacting with the second ramps to generate an axial force on the turbine during a coast condition of the torque converter, the damper assembly being arranged and configured to limit the axial force to prevent the piston from self-locking during the coast condition. A torque converter and a method of forming a drive assembly for a torque converter are also provided.

A differential assembly with a torque coupling unit. The differential assembly includes a first side gear connected to a first axle half shaft. A clutch can end piece is also connected to the first intermediate shaft. A clutch can is connected to the clutch can end piece. A first plurality of clutch plates extend from the clutch can.

A clutch for a vehicle includes a hub disposed on a rotary shaft such that a rotation thereof is restricted, a sleeve spline-coupled to an outer circumference of the hub, a clutch member disposed on the rotary shaft, and a clutch ring disposed between the clutch member and the hub, wherein the clutch ring is pressed against the clutch member by the sleeve and the hub, wherein the clutch ring comprises a pressed part to which an amount of force pressing against the clutch member is applied from the sleeve and the hub, the sleeve comprises pressing protrusions that transfer the axial driving force of the sleeve to the pressed part, and the hub comprises displacement converting portions that convert a relative rotational displacement with respect to the clutch ring into an axial linear displacement of the clutch ring.

A torque coupling unit for use with a differential assembly is provided. The torque coupling unit comprises a first member, a second member, a clutching assembly, and a clutch actuator. The first member is in driving engagement with a side gear of the differential assembly. The second member is in driving engagement with an output shaft. The clutch actuator assembly is disposed adjacent the clutching assembly and comprises a roller and ramp assembly. In response to a rotation of a portion of the clutch actuator assembly a portion of the roller and ramp assembly is driven in an axial manner to apply a force to the clutching assembly, causing a first portion of the clutching assembly to be at least variably frictionally engaged with a second portion of the clutching assembly.
