摘要:
A torque transmitting system including a torque converter or a fluid coupling. The system includes a torsional-vibration damper that is positioned within the housing of the fluid coupling and that serves to damp torsional vibrations. Several locations at which the torsional-vibration damper can be positioned are disclosed.

A hydrokinetic torque converter for use with a transmission in the power train of a motor vehicle has a housing rotatable by the engine and containing a pump, a turbine and at least one stator as well as a rotary output device connected to the input shaft of the transmission. The pump is normally rotatable by the housing; the turbine is rotatable (a) by the fluid which is circulated by the pump or (b) by the housing in response to engagement of a lockup clutch; and the stator can be connected to the stationary case of the transmission or is rotatable by the circulating fluid. First and second hubs are non-rotatably but axially movably mounted on the output member and are respectively connectable with the turbine and the stator by suitable clutches. The hubs can move axially relative to the output device between several positions in one of which the turbine can drive the input element of the transmission in a forward direction, in another of which the stator can rotate the input element in a direction to drive the vehicle rearwardly, and in a third of which the transmission is in neutral gear.

A friction clutch wherein a pressure plate is axially movably but non-rotatably coupled to a cover and is biased by a diaphragm spring to urge the friction linings of a clutch disc against a flywheel which is driven by the engine of a motor vehicle. The diaphragm spring is tiltable relative to a seat which is carried by the cover, and a second spring is provided to bias a portion of the seat against the diaphragm spring. The latter can be moved axially of the flywheel to compensate for wear upon the friction linings, particularly when the flywheel is idle or is driven at a relatively low speed. The device which compensates for wear upon the friction linings is installed between the diaphragm spring and the cover, and its purpose is to ensure that the bias of the diaphragm spring upon the pressure plate in engaged condition of the friction clutch remains at least nearly constant regardless of the extent of wear upon the friction linings and certain other parts including the diaphragm spring, the pressure plate, springs which form part of the clutch disc to urge two sets of friction linings axially and away from each other against the flywheel and the pressure plate, respectively, and leaf springs which connect the pressure plate to the cover.

摘要:
A device for hydraulic control of gas exchange valves of a reciprocating internal combustion engine which has slave cylinders in operative connection with one or more gas exchange valves and master actuators in operative connection with at least one cam provided with a basic and cam profile of a camshaft that is rotatably driven by the engine and can be hydraulically connected to the slave cylinders. The device also has a control device controlled by an actuating member, the device controlling the volume of hydraulic liquid fed to the slave cylinders, and at least one feed line, via which low pressure liquid from a pressure source can be fed to the device by means of at least one non-return valve. The actuators have displaceable vanes, a component carrying the vanes, and cells limited by walls. The vanes are in operative connection with the basic and cam profile of the cam.

An internal combustion engine comprises includes a turbo-compound and the known Föttinger-coupling is replaced by a torsion vibration damper. The Föttinger-coupling, which is used to transmit power, has high losses in power when it is necessary to have a differential rotational speed between the input side and the output side, that is, the appearance of a slip. The losses are not used in a torsion vibration damper which has at least the same quality as a Föttinger-coupling.
摘要:
A torsional vibration damper with at least two parts that are rotatable about an axis and can turn relative to each other against the opposition of at least one coil spring. Support shoes are provided between the spring and an outer wall of the damper structure and are arranged to slide along the outer wall with the spring as it undergoes compression and relaxation. The support shoes include roller bodies to reduce sliding friction between the support shoes and the outer wall.

In a vehicle with a gear-shift transmission of a kind that requires a torque-free state to shift gears, the riding comfort is improved by a method of shifting gears where a gear shift is preceded by the steps of: reducing the vehicle acceleration at a time t1 from an existing level (1) to a first acceleration level (3), maintaining the vehicle acceleration at the reduced level (3) for a predetermined time interval, and at the end point t3 of the predetermined time interval, reducing the acceleration further to a second acceleration level that is lower than the first level.
