The suspension mounting (58) has a parallelogram rod linkage with two or more guide rods (60, 62) and a tensioner (68) inbetween. A servo motor (70) engages on the guide rods parallel to the tensioner and an energy accumulator (72) can be mounted between a guide rod and the motor. the motor can be formed as a simple-acting pressurised medium cylinder and the tensioner can be a spring acting opposite same.
