Abstract: A vehicle braking arrangement includes a braking plate and a link arm arranged to connect the braking plate to a vehicle. The braking plate is movable from a rest position to a braking position where contact is made with the ground. The braking plate is arranged for a first mode of operation, corresponding to the rest position, and a second mode of operation, corresponding to the braking position. In the first mode of operation, the braking plate has a first contact area arranged to face the ground, and in the second mode of operation, the braking plate has a second contact area arranged to face the ground. The second area exceeds the first area.

Abstract: A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arrangement. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes a low pressure container connected to the volume via a valve assembly. Air pressure in the low pressure container is below the air pressure of ambient air in the rest position of the braking plate. The valve assembly is arranged to be opened when the braking plate is in the braking position such that the pressure is lowered in the volume and the braking plate is pressed against the ground by a conferred pressure difference between air outside the volume and air in the volume.
