Abstract:
The present invention relates to a method for preventing rollover of a tractor unit (2) of a working machine (1), the working machine (1) comprising the tractor unit (2) and a trailer unit (4) pivotally connected to each other by a joint arrangement (15) allowing mutual rotation of the tractor unit (2) and the trailer unit (4) around a geometrical axis (302) having a horizontal component in the longitudinal direction of the working machine, wherein the working machine comprises a longitudinal differential gearing arrangement (308) interconnecting a tractor unit drive shaft (306, 402) of the tractor unit (2) and a trailer unit drive shaft (310) of the trailer unit (4); wherein the method comprises the steps of receiving (S1) a signal indicative of an upcoming rollover situation of the tractor unit (2) of the working machine (1); and in response to the received signal, positioning (S2) the longitudinal differential gearing arrangement (308) in a lock-up mode for preventing mutual rotation between said tractor unit drive shaft (306, 402) and said trailer unit drive shaft (310); rotatably fixating (S3) said tractor unit drive shaft (306, 402) to said tractor unit (2) for preventing rotation of said tractor unit drive shaft (306, 402) and said tractor unit (2) relative to each other; and rotatably fixating (S4) said trailer unit drive shaft (310) to said trailer unit (2) for preventing rotation of said trailer unit drive shaft and said trailer unit relative to each other. The invention also relates to a corresponding control unit and a working machine.
Abstract:
Die Erfindung betrifft ein Verfahren zur querdynamischen Stabilisierung eines einspurigen Kraftfahrzeugs während einer Kurvenfahrt, - bei dem das Vorliegen eines in Fahrzeugquerrichtung instabilen Fahrzustandes detektiert wird und - abhängig davon zur Stabilisierung des Kraftfahrzeugs wenigstens eine Düse angesteuert wird, durch welche ein Medium senkrecht zur Radebene eines Fahrzeugrades austritt.
Abstract:
A controller for providing user input of a desired direction of motion or orientation for a transporter. The controller has an input for receiving specification by a user of a value based on a detected body orientation of the user. User-specified input may be conveyed by the user using any of a large variety of input modalities, including: ultrasonic body position sensing; foot force sensing; handlebar lean; active handlebar; mechanical sensing of body position; and linear slide directional input. An apparatus that may include an active handlebar is provided for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle.
Abstract:
An ultra-narrow automobile is comprised of a body (10) with an enclosed cabin (11), a pair of tandem seats (12, 13) inside the cabin, four wheels (14) at the corners of the body, a propulsion system (15) driving at least some of the wheels, and ballast (16) positioned in the body for stability. The cabin is preferably narrow enough to enable two of such automobiles to travel side-by-side on a lane. The ballast is heavy enough and positioned low enough for providing a low center of gravity and a high rollover threshold of preferably about 50 degrees or more. The propulsion system is preferably comprised of an electric motor powered by a fuel cell, and the ballast is preferably comprised of a tank of metal hydride for fueling the fuel cell. The ballast may include dead weight for providing a desired rollover threshold when the batteries are not heavy enough, or when the motor is not an electric motor.
Abstract:
Three or four wheeled vehicle which leans into corners so as to remain stable even when the vehicle has a narrow track. The steering mechanism is such that leaning of the vehicle to either respective side of the vertical causes the front steering wheels (10) to turn in the same steering direction, e.g. a lean to the left causes an anticlockwise, when viewed from above, turning of the front wheels (10). The front wheels (10) can be supported on a parallelogram linkage system (17, 18) so that the steering axis (16) of the wheels (10) remain parallel with the vehicle body as the vehicle leans. Steering can be controlled through a steering wheel (14) which, disregarding the influence of body lean, turns the front wheels (10) in a steering direction relative to the turn of the steering wheel which is opposite in sense, e.g. an anticlockwise turn of the steering wheel (14) produces a clockwise turn, when viewed from above, of the front wheels (10). In order to produce a predetermined steering characteristic the ratio between the angle of lean of the vehicle and the responsive angle of turn of the front wheels (10) varies with the forward velocity of the vehicle.
Abstract:
An ultra narrow enclosed motor vehicle has a chassis (2, 5) supported by a road running wheels (3, 6), which includes a main section (2) pivotally connected to a sub-section (5) whereby pivotal movement can take place between the two sections along a pivotal axis (8) extending in the longitudinal direction of the vehicle. A closed-in body structure mounted on one of the chassis sections (2 or 5) provides for accommodation for at least one person. The drive means for the vehicle is mounted on the other one of the chassis sections. Control means are provided for enabling variable selection of the amount and sense of relative pivotal movement between the two chassis sections.
