Stabilising means

A gyroscopic vehicle stabilising means comprising a pair of rotors, a pair of cradles, each cradle supported from a mounting such that the cradles are in a generally side by side relationship with respect to each other, each cradle comprising a pair of spaced supports, each rotor only being rotatably supported by the supports of a respective one of the cradles, each rotor being rotatably supported such that the rotor is able to rotate about a first axis of rotation, a respective drive supported from each of the cradles and coupled to a respective one of the rotors so as to the enable each rotor to rotate about its respective first axis of rotation at a substantially constant angular velocity, the rotation of the rotors being in opposite directions, each cradle rotatably supported from the mounting through only a single bearing located to one side of the first axis of rotation of each rotor so that the cradle is rotatable around a second axis of rotation which is perpendicular to the first axis of rotation of the rotor, the mounting intended in use to be fixed to the vehicle such that when the rotors are rotating the mean orientation of the first and second axes are substantially perpendicular to the direction of the axis of stabilisation.
