Abstract:
An articulated vehicle with first (1)and second (2) parts, each has a least one road wheel (5), (15) and a longitudinal axis substantially parallel to its intended direction of travel. The first part (1) is pivotally connected to a connecting member at two spaced apart points (17) to pivot about a first axis relative to the connecting member and the second part (2) is pivotally connected to the connecting member at two spaced apart points (18) to pivot about a second axis relative to the connecting member. The first and second axes are substantially perpendicular and intersect at a pivot point. A first drive shaft (28) is rotatably mounted to the first part (1) and extends in a direction substantially perpendicular to the longitudinal axis of the first part, a second drive shaft (26) is rotatably mounted to the second part (2) and extends in a direction substantially perpendicular to the longitudinal axis of the second part. The first and second drive shafts are connected by a universal joint (32) which allows the two shafts to pivot relative to each other about the pivot point.
Abstract:
An articulated vehicle (10) is provided including a stabilization system (56) configured to resist roll-over of a trailer portion (16) of the vehicle. A stabilizer (56) is operably coupled to the chassis of the trailer portion (16) to restrict pivoting movement in response to a condition sensed by a vehicle condition sensor.
Abstract:
An articulated dump truck (1) has a front tractor unit (2) connected to an associated rear trailer unit (3) with a tipping container (12) by an articulated coupling (4). The articulated coupling (4) is operable to allow the front tractor unit (2) and rear trailer unit (3) to pivot about a vertical pivot axis (22), rams (20) being provided to turn the front tractor unit (2) and rear trailer unit (3) about the pivot (22) to steer the dump truck (1). The articulated coupling (4) also allows the front tractor unit (2) and rear trailer unit (3) to rotate relative to each other about a longitudinal axis of the dump truck (1). In addition, the front tractor unit (2) has a front chassis (6) mounted on a pair of wheels (5) by an independent suspension system.
Abstract:
The present invention refers to an arrangement and a method for calibrating a hinge angle sensor (110) on a vehicle (100) comprising a first part (100b) and a second part (100a) connected by a hinge (107) provided with a hinge angle sensor (110) for measuring a hinge angle (α) between the first part (100b) and the second part (100a). In accordance with the invention, the following steps are involved: placing the vehicle (100) so that the hinge angle (α) is roughly 0° and a hypothetical sight line (120) points towards an object (124), in which connection the hinge angle sensor (110) indicates a measured hinge angle; beaming of a medium from a beam-generating device (121) so that the medium generates an image; projection of the image on the object (124); determination of the first position of the image(125) on the object (124); movement of the vehicle (100) towards or away from the object (124) so that the hinge angle sensor (110) continues to display the same measured hinge angle; determination of the second position of the image(126) on the object (124); and adjustment of the zero position of the hinge angle sensor (110).
Abstract:
A tracked vehicle of narrow aspect suitable for unmanned operation both in hazardous environments and on routes normally accessible only to pedestrians, comprises two identical vehicle units (1, 2) each having an independently drivable, full width track (3), the units being interconnected in tandem configuration by an articulation mechanism (9) permitting relative rotation about a yaw axis (Y). In one aspect the articulation mechanism is passive, being arranged with an offset yaw axis, thereby permitting steering by application of a velocity differential to the two tracks. In a second aspect the articulation mechanism is active being powered by an actuator (94) to provide articulation steering. The articulated units may also be secured in parallel configuration for conventional skid-steering operation.
Abstract:
A tracked vehicle with a rearwardly extending ram (13) and an energizing means (14) for the ram, for assisting the vehicle in mounting precipitous objects. A preferred vehicle configuration uses only three, track direction changing rollers (6, 7, 8) so as to locate the centre of gravity (16) of the vehicle as far forward as possible.
Abstract:
Es wird ein Nutzfahrzeug, insbesondere ein Fahrzeug zum Verkehrswegebau, mit einer Fahrerkabine (7) und einer mehrere Trittstufen aufweisenden Einstiegstreppe (9) unterhalb einer Fahrerkabinentür (13) sowie einer Seitenverkleidung (8) beschrieben, welche im Bereich der Einstiegstreppe (9) eine geschlossene Außenfläche (12) bildet. Die Außenfläche (12) weist unterhalb der Fahrerkabine (7) einen sich nach unten vergrößernden Versatz zum Fahrzeug hin auf. Die Außenkanten der Trittstufen stehen aus der Außenfläche (12) unter Bildung der treppenartigen Abstufung in der Weise hervor, dass die unterste Trittstufe am weitesten aus der Außenfläche (12) hervorsteht.

Abstract:
A method for stabilizing at least one frame part of a forest work unit involves determining a moment applied by a payload of the forest work unit to a frame part to be supported and determining a magnitude and direction of at least one support moment needed at least for stabilizing the frame part on the basis of the moment applied by the payload to the frame part to be supported. An arrangement for stabilizing at least one frame part of a forest work unit comprises means for carrying out said determinations.
