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.
The invention has the object of counteracting the cab sinking during the tipping sequence, and the invention is distinguished in that both the spring means and the movement restrainer each has a support mounting in the carrying parts of the cab and that the support mounting of the movement restrainer is arranged forward of the support mounting of the spring means.
