Abstract: An axle arrangement having an outer bevel gear arrangement and an inner bevel gear arrangement. Each bevel gear arrangement allowing large rotation of the axle shaft around a respective swing axis through the bevel gear arrangement, perpendicular to the axle shaft to permit the axle to swing through large angles with negligible impact on transmission of torque. The axle shaft having multiple portions connected in series between the bevel gear arrangements. Between two of the shaft portions is a slidable connection. Between two of the shaft portions is an inner rotatable coupling and between two of the shaft portions is an outer rotatable coupling. Both couplings are stabilised by hinged casings located relative to the bevel gear arrangements with a hinge axis through the rotatable coupling. Each hinge axis is perpendicular to the primary axis of the shaft portion(s) between the rotatable couplings and perpendicular to the respective swing axis.

Abstract: A vehicle (1) having: a chassis portion (2) and a tilting suspension arrangement (10) such that the chassis portion can tilt relative to ground; a tilt control arrangement (50) including at least a tilt controller and a tilt motor (48) to selectively apply a torque between the chassis portion (2) and at least one member (12) of the tilting suspension arrangement (10). The tilt controller has an active, tilt-controlled first mode (200) which adjusts a tilt angle (a) of the chassis towards an unstable equilibrium position using the tilt motor (48). The tilt controller has a primarily passive, free-tilt second mode (220) in which the tilt angle of the chassis is not adjusted for at least fifty percent of time. The tilt controller selectively permits a transition between the first mode and the second mode in dependence on at least one operating parameter of the vehicle.

Abstract: A tiltable motor vehicle having 3 or more wheels and at least one bridge having opposite first and second ends where first and second wheel hub assemblies are disposed. First and second wheels are mounted on the first and second wheel hub assemblies. First and second suspension guides are also associated with the first and second wheel hub assemblies, each being attached to a respective end of the at least one bridge such that the suspension guide is rotatable about at least a tilt axis relative to the at least one bridge. Each wheel hub assembly being movable along or across the respective suspension guide such that the wheels are movable relative to the at least one bridge during suspension action. Movement of the wheels and the wheel hub assemblies associated with suspension rebound and compression action and rotation of the bridges relative to the body associated with tilting action are both substantially independent of movement of the steering element.
