A freight vehicle has a frame defining a support surface for the goods to be transported, a plurality of rubberized wheel assemblies with suspensions, the height of which can be adjusted to shift the support surface between a lowered loading position and a raised transport position, and a driver's cab arranged beneath said support surface; the cab being coupled to, and overhanging, the frame by means of an articulated quadrilateral transmission unit and being shifted by pneumatic actuators configured to vertically move the whole cab in relation to the support surface between two extreme end positions, one approaching the support surface and one spaced apart from said support surface, and to arrange the cab in a cushioned intermediate position for the transport of the goods.

A self-stabilizing vehicle includes a mass gyroscope which is fixed at an occupant compartment chassis corresponding to a portion where occupants sit. The occupant compartment portion may tilt outwards in response to the centrifugal force. If the vehicle has three or more wheels, the load is evenly distributed on the left wheel and the right wheel which move oppositely up and down about an effectively centrally-mounted shaft pin. Further, the present disclosure proposes a method for operating the self-stabilizing vehicle. According to the self-stabilizing vehicle and the operating method thereof, a vehicle having a narrow body may be used. When the vehicle undergoes external forces such as the centrifugal force and the crosswind, the occupant compartment can maintain the vertical stability even though the wheels may slide sideways.

A separated anti-collision car includes a frame and an independent passenger cabin, wherein the independent passenger cabin is arranged on the frame separately, a connected part between a front part of the independent passenger cabin and the frame is provided with a wedge-shaped slope mutually matched with the two, the slope is provided with a damping supporting rod separating the independent passenger cabin from the frame during collision, one end of the damping supporting rod is fixed on the frame, and the other end is connected to the independent passenger cabin; and a back part of the independent passenger cabin is hinged with the frame through an elastic expansion rod.

Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

An electromagnetic vehicle chassis that is configured with an upper portion and a lower portion wherein the upper portion is movable to a second position and supported therein with an electromagnetic field. The vehicle of the present invention includes a frame having the upper portion movable so as to reduce the overall vehicle weight and as such require less propulsion force resulting in reduced energy consumption. The upper portion of the frame of the present invention is moved into its second position utilizing hydraulic cylinders. Electromagnets present on both the upper portion and lower portion maintain the upper portion in its second position. A battery compartment having a plurality of batteries is operably coupled to the lower portion of the frame. The body of the vehicle includes a plurality of photovoltaic cells electrically coupled to the plurality of batteries.
