Abstract
A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arm. 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 an expandable chamber formed between a lower plate, at least one connecting side wall and an upper plate, which chamber is connectable to the volume. Upon activation, the chamber's volume is expanded by movement of the lower plate away from the upper plate. Then the pressure is lowered in the volume which results in that the braking plate is pressed against the ground. In this way, a retaining force is obtained.
