Abstract:
Disclosed is a gearbox with two driver gears that are phase shifted 180 degrees with respect to a driven gear so that counter-rotation of the driver gears combine to rotate the driven gear together. The gearbox can be used to couple a counter-rotating, coaxial wind turbine rotors by coupling the driver gears to the counter-rotating rotors and the driven gear to a generator so that the counter-rotating rotors on the wind turbine rotate the driven gear in the same direction. The driven gear can be coupled to a generator to produce electricity.
Abstract:
The invention concerns a control device for adjusting equipment elements belonging to a motor vehicle, in particular elements for a motor vehicle seat, and comprising an electrical control motor (10) including a control motor shaft (12) and an endless screw (14) set against the shaft, a mechanical adjusting device comprising at least a worm wheel (16) co-operating with the endless screw (14) a coupling unit and an output unit. The invention is characterised in that the coupling unit comprises at least two couplings (28) located on at least an auxiliary shaft (18) coupled rotation-free to the worm wheel (16) and which couple the control motor (10) at the level of at least two output elements (54) of the output unit independently of each other.
Abstract:
Die vorliegende Erfindung betrifft ein Verteilergetriebe zur Verteilung eines Antriebsmoments einer Antriebseinheit eines Kraftfahrzeugs auf eine erste Achse und eine zweite Achse des Kraftfahrzeugs. Das Verteilergetriebe umfasst ein Gehäuse, eine der Antriebseinheit zugeordnete Eingangswelle sowie eine der ersten Achse zugeordnete erste Abtriebswelle und eine der zweiten Achse zugeordnete zweite Abtriebswelle, die bezüglich der Eingangswelle parallel versetzt ist. Ferner umfasst das Verteilergetriebe einen Versatztrieb zur Übertragung von Antriebsdrehmoment von der Eingangswelle auf die zweite Abtriebswelle, wobei der Versatztrieb ein zu der Eingangswelle oder zu der Abtriebswelle koaxiales Zahnrad umfasst. Das Zahnrad ist an einem Abschnitt des Gehäuses des Verteilergetriebes drehbar gelagert.
Abstract:
A powertrain with a disconnecting rear drive axle generally includes a prime mover including an output that rotates about a rotational axis. A transmission includes an output that rotates about a rotational axis. The rotational axes of the outputs are substantially parallel to a longitudinal axis of the powertrain. A front driveline is operable to direct rotary power from the prime mover to front vehicle wheels. A rear driveline includes a propeller shaft that provides rotary power to a first shaft member and a second shaft member through a pinion and a ring gear. The first shaft member and the second shaft are operable to connect to rear vehicle wheels. A power switching mechanism has an engaged condition and a disengaged condition. The power switching mechanism is operable to direct the rotary power from the transmission to the rear driveline in the engaged condition. A torque transfer device has an engaged condition and a disengaged condition. The power switching mechanism and the torque transfer device in the disengaged condition are operable to only transmit rotary power to the first vehicle wheels. The torque transfer device in the disengaged condition prevents the first shaft member and the second shaft member from back-driving the ring gear and the pinion of the rear driveline. The power switching mechanism in the disengaged condition prevents the transmission from driving the propeller shaft.
Abstract:
Es wird ein Verfahren zum Umbau eines Verteilergetriebes für mehrere Abtriebe beschrieben, die an einen gemeinsamen Antriebstrang über Zwischenzahnräder (3, 4) angeschlossen sind, deren Lagergehäuse (7) die axial ausbaubaren Radachsen (6) aufnehmen, wobei die einzelnen Abtriebe vom gemeinsamen Antriebstrang abgekoppelt und an Einzelantriebe angeschlossen werden. Um einfache Umrüstbedingungen zu schaffen, wird vorgeschlagen, dass die Radachse (6) zumindest eines Zwischenzahnrads (3, 4) in der Antriebsverbindung zwischen dem jeweiligen Abtrieb und dem gemeinsamen Antriebstrang durch eine über exzentrische Stirnzapfen (10) vorzugsweise exzentrisch in Lagerdeckeln (11) gelagerte Stellachse (8) ausgewechselt wird, bevor das Zwischenzahnrad (3, 4) durch ein Drehen der Stellachse (8) um die Stirnzapfen (10) außer Eingriff geschwenkt wird.
Abstract:
A dual speed drive system (10) for alternatively driving a pair of parallel output shafts (12) at one or the other of two different speeds, comprises a pair of parallel idler shafts (14a, b) interposed between the output shafts (12). A first gear train for mechanically couples the idler shafts (14a, b) to each other and to the output shafts (12). An input shaft (20) is aligned coaxially with and rotatable independently of one of the idler shafts (14a, b), and first and second drive gears (22,26) are respectively received on and are rotatable relative to the input shaft (20) and the one idler shaft (14a, b). A second gear train mechanically couples the first drive gear (22) to the second drive gear (26). The second gear train is configured and arranged to effect rotation of the second drive gear (26) in the same direction as and at a different speed from that of the first drive gear (22).
Abstract:
A power multiplier having a housing which houses a gear assembly having four gear sets each having input gears affixed to each other by an off-set input axle, output gears affixed to each other by an off-set output axle and linkages which connect the off-set input axles to the off-set output axles thereby allowing the input gears to transfer rotational force to the output gears The gear sets are connected to each other by central input axles and central output axles The placement of the off-set output and off-set input axles progressively differs by ninety degrees clockwise going from the first gear set to the fourth gear set The placement of the off-set output and off-set input axles in this manner allows for an equal distribution of rotational force around the central output axles thereby creating additional torque
