20120221195 | METHOD AND A SYSTEM FOR TESTING THE BRAKING CAPACITY OF ONE OR MORE BRAKE ELEMENTS OF A VEHICLE - A method and a system are provided for testing the braking capacity of one or more brake elements of a vehicle, where the vehicle includes a power source for propulsion of the vehicle and at least one ground engagement element driven by the power source, and at least one brake element arranged for braking the vehicle by acting on a rotation component of the vehicle. At least one brake element is automatically activated by applying a predetermined brake force, and a predetermined decision torque level is applied to the rotation component by means of the power source, wherein the decision torque level is indicative for the braking capacity of said at least one brake element when said predetermined brake, force is applied. It is determined whether or not there is a motion of the vehicle and/or of said at least one ground engagement element when the decision torque level is applied in order to decide on the braking capacity of said at least one brake element. | 08-30-2012 |
20120097822 | SEAT SUSPENSION ARRANGEMENT AND METHOD FOR PRESTRESSING A GUIDE ASSEMBLY - A seat suspension arrangement includes an upper structure for receiving a seat and a lower structure for mounting the seat in a work machine or vehicle. The tipper structure and the lower structure are interconnected by at least one intermediate structure and displaceable towards and away from each other. The seat suspension arrangement includes a guide rail and a guided member which is connected to the intermediate structure and arranged at the guide rail. The guided member is arranged to be displaced forwards and backwards along the guide rail when the upper structure and the lower structure are displaced relative to each other. | 04-26-2012 |
20110301781 | METHOD FOR CALIBRATING AN ANGLE SENSOR AND VEHICLE WITH AN ANGLE SENSOR - A method for calibration of at least one angle sensor sensing an angular position of a pivotable element rotatable from a first position to a maximum position is provided, wherein during an operation time of the pivotable element at least one adjustable angle corresponding to an extreme value of the angle sensor is automatically maintained or updated depending on at least one measured angle determined by the at least one angle sensor. | 12-08-2011 |
20100036568 | METHOD FOR OPERATING A WORKING MACHINE AND A WORKING MACHINE WITH AN IMPROVED ABILITY TO MEET TRANSIENT LOADS - A working machine and a method for operating a working machine are provided. The working machine includes a power source and a plurality of driving wheels; a working hydraulic system including at least one hydraulic pump powered by the power source for moving an implement on the working machine and/or for steering the working machine; a transmission line arranged between the power source and the driving wheels for transmitting torque from the power source to the driving wheels. The method includes detecting at least one operational parameter indicative of a load exerted on the working hydraulic system, determining if torque needs to be added, in addition to a torque delivered by the power source, on the basis of a magnitude of the detected operational parameter in order to reduce the a load on the power source, and adding torque in case additional torque is determined to be needed. | 02-11-2010 |
