Abstract:
Ein Verteilergetriebe für Kraftfahrzeuge besteht aus einem Gehäuse (1, 2), einer Primärwelle (4) und einer Sekundärwelle (7), wobei eine aus einem mit der Primärwelle drehfest verbundenen Aussenteil (11) und aus einem Innenteil (12) bestehende Reibungskupplung (8) von der Primärwelle (4) Drehmoment abzweigt und über den Innenteil (12) und einen Versatztrieb (18, 19, 22) der Sekundärwelle (7) zuführt. Um unter allen Bedingungen eine ausreichende Versorgung mit Schmieröl sicherzustellen, ist im Gehäuse (1, 2) zwischen Kupplung (8) und Versatztrieb (18, 19) ein die Rampenringe (25, 26) teilweise umgreifendes Ölreservoir (30) befestigt, dessen Boden (31) mindestens eine erste Öffnung (40) hat, die an einen oberen Teil des Umfanges der Rampenringe (25, 26) anschließt, und hat das Ölreservoir (30) mindestens eine in den Schleuderbereich des Versatztriebes (18, 19) reichende Leiteinrichtung (36), durch die abgeschleudertes Schmieröl in das Reservoir (30) gelangt.
Abstract:
The present invention relates to a limited slip differential with friction using a pressure generating device for performing a slip differential function of a vehicle and simultaneously, by limiting a portion of the slip differential function for movement of the vehicle when a big slip differential occurs, for rotating both wheels smoothly comprising a body section (12) having a fixed cover (11), a first side pinion gear (14) arranged inside of said body section (12) and connected with a driving shaft of a vehicle , a second side pinion gear (13) rotatably connected with a driving shaft of vehicle opposite to said first side pinion gear (14), a pair of differential pinion gears (15, 16) each of which is rotated in engagement with said first side pinion gear (14) and second side pinion gear (13), friction plates arranged at rear sides of said first side pinion gear (14) and second side pinion gear (13), and a pressure generating device (20) constructed such that its cover gear (22) and piston gear (25) engage with said second side pinion gear (13) and first side pinion gear (14), respectively, and can be displaced away from each other in a longitudinal direction of said device.
Abstract:
Die Erfindung betrifft eine Lamelle (19) und eine Herstellungsverfahren für ein solche. Um Rubbeln der Lamellen zu vermeiden, wird eine Schrägverzahnung (30a, 30b) vorgeschlagen. Diese kann als Laufverzahnung ausgeführt sein, so dass mit der selben Verzahnung zusätzlich eine Zahnradpaarung ausgeführt ist. Um bei einer solchen Schrägverzahnung zu verhindern, dass die Schrägverzahnung der Welle die Verzahnung der Lamelle im Kantenbereich zerdrückt, werden die Zähne der Lamelle verdreht ausgeführt, so dass die Zähne flächig an der Schrägverzahnung anliegen. Anwendungsbeispiel ist ein kombiniertes Lastschlagelement/Zentraldifferential eines Allrad-Antriebsstranges, wobei die Funktion eines Lastschlagelementes massgeblich davon abhängt, dass die Zähne der Lamelle kein Spiel zur Welle aufweisen.
Abstract:
A differential mechanism (1) includes a carrier housing (2) adapted to be rotatably driven about a longitudinal axis (3). A pair of independent coaxial parallel side gears (4, 5) are supported for rotation about the axis (3). The carrier housing (2) includes two inner peripherally spaced part-spherical recessed pinion cavities (6) defining respective inwardly directed housing thrust surfaces (7). Two floating bevel pinions (8), each in a meshing engagement with the side gears (4, 5), have respective pinion outer and inner thrust surfaces (9, 10). The outer thrust surfaces (9) are adapted for frictional rotation within the recess cavities (6). A cubic thrust block (12) is supported generally within the carrier housing (2) by a cross shaft (11) and defines four outwardly directed thrust directed thrust surfaces (13, 16).
Abstract:
A differential mechanism, of either the locking or limited slip type, including a gear case (11) rotatably disposed within an outer housing (H) and means (37) to limit rotation of side gears (23,25) relative to the gear case (11), this means (37) including a member (41) which is axially moveable between a first position ( FIG. 2 ) and a second position ( FIG. 5 ). The mechanism incudes a sensor assembly (95) and a sensor element (97) disposed adjacent the gear case (11). The axially moveable member (41) includes a sensed portion (89) surrounding an annular outer surface (11S) of the gear case, and disposed between the annular outer surface (11S) and the sensor element (97). Movement of the sensed portion (89) corresponding to changes within the mechanism between, for example, the unlocked and locked conditions, results in the sensor assembly (95) transmitting either a first or second electrical output. Thus, the present invention permits the vehicle control logic to know the condition of the differential mechanism and control certain other parts or functions of the vehicle accordingly.
Abstract:
An axle assembly with an electronic locking differential that employs a locking mechanism having components that are fixed to one another along an axis such that they co-translate with one another when the actuator that effects the locking and unlocking of the differential is operated. A method for assembling a differential is also provided.
Abstract:
The present invention relates to a differential gear equipped with a selectively controllable locking device. Said locking device is self energizing, i.e. it utilizes the differentiation energy (i.e. the possible torque imbalance) to self- lock on its own accord. The control signal is therefore not needed to lock the locking device but rather to selectively control it not to lock itself. Said control signal is designed to, separately for each of the two possible differentiation directions, allow or not allow the locking device to lock. In this way the differential gear will get four different working modes. Said working modes are respectively; open regardless of differentiation direction; open in one differentiation direction but self-locking in the other direction; open in the other direction but self-locking in the first one; self-locking regardless of differentiation direction. A control unit is supplied with sensor data of the present 'driving situation'. Said control unit has a steering strategy. With the right steering strategy it can regulate the control signal so as to admit the differential gear to equalize the torque at each output shaft for as long as possible but still to practically eliminate the risk of one wheel spin.
