Abstract:
Es wird ein Verfahren zum Betreiben eines geländegängigen Fahrzeuges (1) mit Knicklenkung (2) beschrieben, das antreibbare Fahrzeugachsen (3 bis 5) aufweist, die über ein stufenlos sperrbares Längsdifferential (8) miteinander in Wirkverbindung stehen. Im Bereich jeder antreibbaren Fahrzeugachse (3 bis 5) ist ein stufenlos sperrbares Querdifferential (9 bis 11) vorgesehen. Im Betrieb des Fahrzeuges (1) werden Ist-Drehzahlen der Räder (3A bis 5B) über Drehzahlsensoren (3C bis 5D) sowie ein aktueller Ist-Lenkwinkel über einen Lenkwinkelsensor (2A) messtechnisch ermittelt. Zusätzlich wird eine Ist-Fahrzeuggeschwindigkeit über einen Geschwindigkeitssensor messtechnisch ermittelt oder eine Soll-Fahrzeuggeschwindigkeit in Abhängigkeit einer Ist-Ausgangsdrehzahl des Getriebes (7) berechnet und gleich der Ist-Fahrzeuggeschwindigkeit gesetzt. Unter Berücksichtigung des Ist-Lenkwinkels sowie des Abstandes (32G, 42G, 52G) der Fahrzeugachsenmitten (3G, 4G, 5G) in Fahrzeuglängsrichtung von der Knicklenkung (2) und der Spurbreiten der antreibbaren Fahrzeugachsen (3 bis 5) werden in Abhängigkeit der Ist-Fahrzeuggeschwindigkeit Soll-Drehzahlen der Räder (3A bis 5B) berechnet. Bei Vorliegen positiver Abweichungen zwischen den Ist-Drehzahlen und den Soll-Drehzahlen der Räder (3A bis 5B) größer als ein Schwellwert werden die Übertragungsfähigkeiten der reibschlüssigen Schaltelemente der Querdifferentiale (9 bis 11) jeweils auf ein die Abweichung auf werte kleiner oder gleich dem Schwellwert führendes Niveau eingestellt.
Abstract:
A powertrain system (70) for a mobile machine (10) is disclosed. The powertrain system may have a power source (34), a plurality of traction devices (28), and a differential (32) operatively connecting an output of the power source with the plurality of traction devices. The powertrain may also have a manual input device (38) movable by an operator to generate a first signal indicative of a desire to lock the differential, at least one sensor (74, 76) configured to generate a second signal indicative of a parameter the mobile machine, and a controller (72) in communication with the at least one sensor, the manual input device, and the differential. The controller may be configured to inhibit locking of the differential based on the first signal when the second signal indicates the parameter deviating from an acceptable range.

Abstract:
An arrangement and method for enabling rotation movement between a tandem or caterpillar axle and a body of a vehicle. This type of vehicle comprises at least one body part (1, 5) that is provided with a tandem or caterpillar axle (3, 7). At least one body part (1, 5) comprises a main body (9, 9b) and an auxiliary body (11, 11 b) connected to it to rotate around the longitudinal axis (10) of the vehicle or an essentially parallel axis thereto. The tandem or caterpillar axle is connected substantially rigidly to said main body, and the body part (1, 5) has at least one actuator (12, 12b) for controlling the rotation movement between the main body (9, 9b) and auxiliary body. This way, changes in the position and motion status of the auxiliary body especially in relation to the rotation around the longitudinal axis (10) of the vehicle are arranged to cause in the actuator (12, 12b) a pushing or pulling motion that steers the auxiliary body (11, 11b) to a rotation movement for the purpose of arranging the auxiliary body to a substantially horizontal position.
Abstract:
A method of controlling a dual powertrain machine (10) includes propelling the dual powertrain machine (10) by transmitting power from a first engine (66) of a primary electronically controlled powertrain (62) to a first set of ground engaging elements (22), and transmitting power from a second engine (82) of a secondary electronically controlled powertrain (64) to a second set of ground engaging elements (38). The method also includes identifying a runout condition of the primary electronically controlled powertrain (62), and limiting a power output of the secondary electronically controlled powertrain (64) responsive to the runout condition.
Abstract:
The present invention relates to a method for controlling a differential configuration (40; 400) for at least two for differential drive arranged drive wheels of a motor vehicle (1; 2; 3), said differential drive being arranged to assume a locked and an open position respectively comprising the step of in a condition keeping at least on differential drive in an essentially locked position, comprising the steps of: - in a normal case of prevalent vehicle drive keeping (S1) the differential configuration (40; 400) in a locked condition for securing the traction capability; and - controlling (S2) the differential configuration to an non-locked condition by deviations from said normal case of prevalent vehicle drive represented by predetermined vehicle parameters for continued securing of the traction capability of the vehicle. The present invention also relates to a system for controlling a differential configuration (40, 400). The present invention also relates to a differential configuration. The present invention also relates to a motor vehicle. The present invention also relates to a computer program and a computer program product.

The arm has a compartment formed in the arm and an opening extending through the arm at a base of the compartment. The cylinder actuator includes a piston connected to a rod, and is positioned substantially in the compartment of the arm. The rod extends toward the opening of the arm, and the rod moves through the opening during operation of the cylinder actuator. Also, the first protrusion extends from the arm in a first direction and the second protrusion extends from the arm in a second direction.

The present invention relates to a transmission assembly (48) comprising an input shaft (64) and an output shaft (66). The transmission assembly (48) comprises a planetary gear assembly (68) which in turn comprises a ring gear (70), a first and a second sun gear (72, 74) and a planet gear connecting assembly connecting the ring gear (70) to each one of the first and second sun gear (72, 74). The planet gear connecting assembly (76) comprises a radially outward planet gear (78) and a radially inward planet gear (80) meshing with the radially outward planet gear (78). The radially outward planet gear (78) and the radially inward planet gear (80) are connected to one another via a common planet carrier (82). The input shaft (64) is connected to the common planet carrier (82). The first sun gear (72) meshes with the radially outward planet gear (78) and the second sun gear (74) meshes with the radially inward planet gear (80). Each one of the second sun gear (74) and the ring gear (70) is selectively and individually connectable to the output shaft (66).
