Abstract: Method of simulating the performance of a vehicle on a roadway on a power train test bed with the help of torque-controlled electric load machines mounted on the shafts of the power train of the vehicle and with the help of a computer with a vehicle model stored therein and a tire model simulating the slip-dependent friction, in which method the angular wheel speed is measured on at least one of the shafts, and the tire model determines a force transmitted from the tire to the roadway at this angular wheel speed on the basis of the tire model using a vehicle velocity and a tire normal force, and it also determines a setpoint torque for this force for the torque-controlled load machine mounted on this shaft, in such a way that a difference corresponding to the actual slip is established between the measured angular wheel speed and a nominal angular wheel speed value corresponding to the vehicle velocity used in the tire model and calculated in the vehicle model with feedback of the force transferred to the roa

Abstract: In a device for moving a loading tailgate or similar swivelable body on, for example, a loading platform (1) of a vehicle, the loading tailgate is connected to a drive (3) via struts (5, 6) or support struts. In this case, at least two struts (5, 6) are to have, on the one hand, separate linkage points (7, 52) with the loading tailgate (4) and, on the other hand, they are to be connected to coupling profiles (30, 31) of the drive (3) rotating about a longitudinal axis (11).

Abstract: The disclosure describes a method of automatically attaching an arrow label in the center hole of a ball, skein or package of yarn or thread wound onto a winding mandrel. The arrow label is coaxially aligned with the winding mandrel. During withdrawal of the ball of yarn from the winding mandrel the ball slides with its center hole onto the label. Subsequently, the ball of yarn is transported away together with the label by a conveyor means. A device for carrying out this method is provided with a movable label conveyor which positions the arrow labels one at a time and tip first at the winding mandrel. A movable gripping device then withdraws the ball of yarn from the winding mandrel, slides it over the shaft of the arrow label and transfers the labelled ball to ball conveyor.
