Abstract: The axle suspension for vehicles, particularly heavy and special vehicles, has an axle housing connection using two telescopic assemblies (26, 20, 21, 24, 87) each having a telescopic cylinder (6, 95) and a telescopic tube (2, 23, 43, 91) displaceable therein with a working piston (20, 44, 55, 82) at one end and a hinged connection (3) at the other. The telescopic cylinder (6, 95) as a mounting tube is fixed to the chassis (5) and the telescopic tube (2, 23, 43, 91) is connected in articulated manner to axle (4), in such a way that the axle is pivotable at right angles to the vehicle, but cannot be rotated about its own axis. The telescopic assemblies guiding the axle (4) accomplish the vehicle suspension, as well as vertical adjustment and slope compensation of the vehicle.
Abstract: A vehicle suitable for various uses in rough terrain. The vehicle has a platform or chassis (11) suspended within a flexible frame (14). The wheels (17, 18) are mounted at opposite ends of side members (23, 24) of the flexible frame (14). The platform connects to the neutral midpoints of the frame rails so as to minimize the movement of the platform or chassis out of the horizontal plane. Rotating drive shafts may enter or pass through hollow pivot pins at the midpoints of the members of the frame (14) thereby remaining on the same plane with one another and isolated from flexing from the frame. The platform may serve as a mounting for a seat (16) of the vehicle. It may also be utilized as a support for the engine (15) of the vehicle.
Abstract: A device and method that will safely elevate a wheel chair to a greater height, hold said wheel chair in a safe elevated position and allow a person confined to said wheel chair to achieve the height of that of a standing person. The feet of the wheel chair are first rotated outward and lowered onto the floor, the wheel chair is then elevated by air pressure to a desired height and locked off for safety. When the wheel chair is being elevated or lowered, it will automatically lock off if the chair becomes unlevel for any reason.
