A torque-transmitting apparatus for motor vehicles includes a hydrokinetic torque converter with a housing connected to the driving shaft of an engine. The housing contains a pump and a turbine, the latter arranged to drive an input shaft of a power train. At least one damper is arranged in the power flow path between the turbine and a rotary output element of the apparatus. The damper has an input member constrained to rotate with the turbine and an output member connected to the rotary output element. The input member and the output member are rotatable relative to each other against the opposing forces of energy-storing devices arranged between the input member and the output member. The input member has a radially outer portion in form-locking engagement with the turbine.

Torque-transmitting apparatus

A clutch disc, particularly for use between a pressure plate and a counterpressure plate in a friction clutch which is installed in the power train of a motor vehicle, has two friction linings flanking resilient carriers mounted on a washer which has a hub connectable with a torque receiving part, such as the input shaft of a change-speed transmission. The carriers are connected with reinforcing sections of the friction linings by rivets in such a way that the friction linings and the washer are movable radially relative to each other. This reduces the likelihood of excessive wear upon the friction linings in response to repeated engagement and disengagement of the clutch.

Clutch disc

A torque-transmitting apparatus, particularly for motor vehicles, with a fluid coupling or a hydrodynamic torque converter and a damping system has an improved design providing the advantages of stress-free mounting of the damper, technical and cost improvements in the manufacture of the apparatus, modular assembly, capability to transmit large torque and attenuate rotational perturbations over a wide RPM range so as to minimize wear to prolong the useful life of the entire unit.

The invention relates to hydrodynamic torque converter comprising a pump wheel which is arranged inside of a housing, a turbine wheel, a stator, a torque converter lock-up clutch and a torsional vibration damper. The turbine wheel has a turbine hub which is axially and rigidly mounted on a drive hub of the torque converter in an axial direction to the drive hub by means of at least one axial bearing. The turbine hub is mounted in a radial direction by means of a radial bearing. A connection with circumferential backlash is provided between the turbine hub and the drive hub by means of a disengaging gear. The invention also provides a rotationally fixed connection by means of an engaging gear located between the input component of the torsional vibration damper and the turbine hub, whereby the engaging gear and the disengaging gear are arranged on an essentially same axial position and radially within one another.

Hydrodynamic torque converter

An improved apparatus and method for assembly of a hydrokinetic torque converter which comprises a hydraulic pump, a turbine, a stator, a driven hub, and a housing that is driven by the output element of an engine of a motor vehicle, and which functions to transmit torque to the hydraulic pump is disclosed. In such a torque converter the housing is coaxial with the pump and the turbine, and further defines an interior chamber, which encloses the turbine as well as a bypass or lockup clutch cooperating with a torsion damper having an input member and an output member. The present invention provides a positive interlocking connection between the output member of the torsion damper and the driven hub of the turbine by forming a circumferential array of staked protuberances in the driven hub to compressively engage a mating circumferential serration formed in the output member to prevent axial rotation thereof Thus, the inherently complex manufacturing processes required to form the internal and external splines conventionally utilized to interlock such components are eliminated thereby reducing the manufacturing costs of the torque converter. In addition, other components of the torque converter cooperating with the torsion damper are integrated into a single component to reduce space requirements of the torque converter.

Force transmitting apparatus

The hydrodynamic torque converter (,) comprises a pump wheel (,) in a casing (,), a turbine wheel (,) and a turbine distributor (,). There is also a bypass coupling (,) including an axially moving piston, a torsional oscillations absorber (,) with input and output parts rotating relative to each other in opposition to force accumulators. Its turbine wheel comprises a hub (,) housed axially on the torque converter output hub (,). A connection with the rotational clearance, the splines (,), is provided between the two hubs. A fixed connection, by splines (,) is between the input part of the absorber and the turbine wheel hub. The two sets of splines are in the same axial position radially one in the other.
