A positioning apparatus for positioning a tubular fluid container in an elongate carrier which is configured as a hollow profile. In order to simplify the positioning of the tubular fluid container, the positioning apparatus includes spring elements, by way of which the tubular fluid container is positioned in the elongate carrier.

The relates to an energy absorption element for a support frame of a motor vehicle and is characterized in that a cross-sectional profile is designed as a hollow profile which remains constant along a longitudinal direction of the energy absorption element having at least two closed chambers, so that the energy absorption element comprises at least two mutually separate chamber cavities and the at least two chamber cavities have an elongated shape along the longitudinal direction of the energy absorption element and each chamber cavity is open at two longitudinal ends of the energy absorption element and each chamber cavity is fluidly connected to a sound generator.

Ground vehicles that may include flight capability are described. In some examples, a vehicle frame may include a main support and at least two auxiliary supports, with the main support disposed substantially along the centerline of the vehicle, and the at least two auxiliary supports extending upward and outward from the main support. In some examples, vehicles may include an inflatable airfoil, such as a ram air parachute, that includes stiffeners on or about a leading edge of the airfoil. In some examples, vehicles may include a front wheelbase attached to the main support and/or auxiliary supports, a rear wheelbase attached to the main support and/or auxiliary supports, a ground steering mechanism connected to the front wheelbase and/or the rear wheelbase, a motor connected to a propeller, and a propeller shroud at least partially encircling the propeller.

A vehicle reinforcing member includes first and second pistons movable in an axial direction in a cylinder. An inside of the cylinder is sectioned into a gas chamber and a main liquid chamber by the first piston, and the main liquid chamber is sectioned into a first sub-liquid chamber and a second sub-liquid chamber by the second piston. Gas is sealed in the gas chamber, and liquid is sealed in the first and second sub-liquid chambers. A piston rod is coupled to the second piston. The cylinder and the piston rod are respectively coupled to two locations of a vehicle body. A communication path connects the first sub-liquid chamber to the second sub-liquid chamber. A moving amount of the liquid in the communication path is adjusted by an adjuster such that a moving load through the second piston is adjusted.

A hybrid energy storage and delivery device includes a plastic enclosure that establishes a first sealed chamber and a second sealed chamber. The first sealed chamber is configured as a fuel tank for storing a liquid fuel and the second sealed chamber is configured as a battery pack for storing electrical energy. Thus, the fuel tank and battery pack may be integrated together within a single enclosure in order to improve vehicle packaging efficiencies.

A recreational vehicle may include a chassis, at least one axle assembly, and a vehicle body. The vehicle body may be supported by the chassis. The axle assembly may be coupled to the chassis and may provide motive support and underbody clearance to the chassis. The chassis may include a plurality of longitudinal main rails that span at least a portion of a length of the recreational vehicle and define a length of at least one crawl space. The plurality of lateral crawl space cross members may extend between and interconnect the plurality of longitudinal main rails and define a width of the at least one crawl space. A floor of the recreational vehicle, the plurality of longitudinal main rails, and the plurality of lateral crawl space cross members may collectively define the at least one crawl space.
