Abstract: A method and a system for effecting a specific transmission ratio in a motor vehicle between a first shaft of a gearbox and that a shaft of a power take-off, wherein rotary motion is transmitted from a first motion-transmitting element on the first shaft to a third motion-transmitting element on the third power take-off shaft via a second motion-transmitting element situated between them. The method and the system are characterised in that the motion-transmitting element is selected with a diameter such that it is situated at a predetermined first between-centres distance from the second motion-transmitting element which is substantially equal to a second between-centres distance (y) between the first and second motion-transmitting elements. The present invention also relates to a bearing bracket which at least partly houses the motion-transmitting element and which is characterised by at least one spacing element intended to be situated between the flange and the gearbox.

Abstract: The invention relates to an arrangement for the suspension of a forwardly tippable cab on a vehicle frame with at least one spring means and one movement restrainer arranged between the cab and the frame, said spring means being adapted to absorb the oscillations of the cab and the restrainer being adapted for restricting the vertical movement of the cab relative the frame.When tipping the cab on the kind of vehicle mentioned above, the center of gravity of the cab is moved, whereby the weight of the cab is successively transferred to the spring means. The latter then contracts and the necessary play between the vehicle drive unit and lower portions of the cab necessary for tipping the cab decreases, resulting in that the cab can collide with the drive unit.
