A torque converter includes a cover assembly, an impeller assembly, a turbine assembly and a damper assembly. The impeller assembly includes an impeller shell drivingly connected with the cover assembly. The turbine assembly includes a shell with a clutch portion for selective driving engagement with the impeller shell. The damper assembly includes at least one cover plate, a flange for driving engagement with a transmission input shaft, and a first resilient element drivingly engaged with the at least one cover plate and the flange.

The present invention relates to a lock-up clutch of a torque converter. A cover (10) is separated to a pilot (48) and includes an opening (10-1) for installing the pilot (48). Before assembling a clutch driving portion such as a piston, a separator, drive plates, a seal ring, and driven plates, to the pilot (48), rivets (53) are press-fitted into the pilot (48), the cover (10) is abutted to respective head portions of the rivets (53), and the pilot (48) is installed in the cover (10) and is fixed to the cover (10) by welding. Thereafter, the piston, the drive plates and the driven plates are disposed between the separator and the cover (10), the seal ring is contact with the separator, the separator is press-fitted into projection ends of the rivets (53), and then projection portions (53-2) of the rivets (53) are crimped.

A torque transmission unit includes a first input side, a second input side, an output side, a hydrodynamic converter and a lock-up clutch. The first input side is configured to receive a first torque, and the second input side is configured to receive a second torque. The torque transmission unit has a freewheel. The freewheel is arranged downstream of the hydrodynamic converter, and the second input side is arranged downstream of the freewheel in a torque flow of the first torque from the first input side to the output side. The freewheel is designed to, in a first freewheel operating state, connects, in a torque-locking manner, the hydrodynamic converter to the output side for the transmission of the first torque from the first input side to the output side when the lock-up clutch is open. The freewheel is designed to, in a second freewheel operating state, decouple the hydrodynamic converter from the output side, to at least partially prevent a transmission of the second torque from the second input side into the hydrodynamic converter.

The hub defines a plurality of second holes circumferentially arranged in a second pattern that corresponds to the first pattern. Connectors are disposed in the first and second holes to connect the hub to the driven disc.

A force transmission device, in particular or power transmission between a drive engine and an output, comprising a damper assembly with at least two dampers, which can be connected in series, and a rotational speed adaptive absorber, wherein the rotational speed adaptive tuned mass damper is disposed between the dampers at least in one force flow direction through the force transmission device.

A torque transmitting device for transmitting torque between a first drive element and an output element, having a torque transmitting unit with a housing delimiting a first fluid chamber filled with a liquid, and a separating clutch arranged outside of the torque transmitting unit and the first fluid chamber in a second fluid chamber separated from the first chamber and which selectively transmits torque between the first drive element and the torque transmitting unit. The separating clutch has a clutch output that is connectable to a clutch input via a friction device and a clutch actuator that comprises a pressing element and an actuation element to which fluid pressure can be applied to move the actuation element. The pressing element is arranged within the second fluid chamber, and the actuation element is at least partly arranged within the first fluid chamber so that pressure is applied thereto by fluid pressure.

A flow channel structure forms a first flow channel which makes a first fluid chamber and a second fluid chamber communicate with each other therethrough. The flow channel structure includes first to third plates. The first plate includes a first through hole penetrating the first plate in a thickness direction to open to the first fluid chamber. The second plate includes a second through hole penetrating the second plate in the thickness direction to open to the second fluid chamber. The third plate includes a first connecting through hole penetrating the third plate in the thickness direction. The first connecting through hole is larger in flow channel area than each of the first and second through holes. The first and second through holes are disposed in different positions from each other as seen in the thickness direction. The first connecting through hole communicates with the first and second through holes.

A hydrodynamic torque converter is provided with a converter housing and a converter torus with a pump impeller, a turbine wheel which is driven hydrodynamically by the pump impeller by a converter fluid. In order to bridge the hydrodynamic drive, a converter lock-up clutch which is connected between the pump impeller and the turbine wheel by pressure loading of the converter fluid is arranged radially between an outer circumference of the converter housing and the converter torus. In order to provide the converter lock-up clutch with an increased transmission capacity, the turbine wheel is assigned at least one friction disc which can be prestressed axially between a pressure-loaded annular piston, which is hooked in an axially movable manner into the converter housing, and a mating friction surface of a converter housing section radially outside the converter torus.

A torque converter is provided. The torque converter includes a front cover including a front radially extending section and a front axially extending section extending axially from an outer radial end of the front radially extending section. The torque converter also includes a plurality of baffle assemblies each including a base connected to the front radially extending section and a support connected to the base. Each of the baffle assemblies includes a first baffle and a second baffle extending radially inward from the respective support. A method of forming a torque converter is also provided. The method includes providing a plurality of baffle assemblies each including a base, a support connected to the base and a first baffle and a second baffle extending from the support; and fixing the bases of the baffle assemblies to a radially extending section of the front cover such that the first and second baffles extend radially inward from the respective support.
