A method and apparatus for performing an assembly operation. A tool may be macro-positioned relative to an exterior of a fuselage assembly. The tool may be micro-positioned relative to a particular location on the exterior of the fuselage assembly. An end effector is removably associated with an external robotic device associated with an external mobile platform. The tool is removably associated with the end effector. An assembly operation may be performed at the particular location on the panel using the tool.

Implementations extend to a height adjustable single axle trailer. The trailer can be configured for efficient loading, transportation, and unloading of vehicles, such as side-by-side vehicles. In one implementation, the trailer's T-shape frame includes a longitudinal support with a latitudinal support (axle) affixed to the longitudinal support's rear end. The trailer further includes a hydraulic pump, a battery, and a remote control to operate the raising and lowering of the trailer. The trailer also features first and second suspension arms connected to the latitudinal support, each incorporating lower and upper housings, hydraulic rams, and springs housed within the lower and upper housings, thereby enabling flexible movement of the latitudinal support of the trailer. The hydraulic rams can be controlled to transition the latitudinal support between a lower loading position and an upper transport position.

A universal wishbone trailing arm and methods are provided for coupling a wheel to a vehicle chassis. The universal wishbone trailing arm comprises a wheel hub that fastenably receives the wheel. A cylindrical axle support supports one or more roller bearings whereby the wheel hub is rotatable. A first swing arm and a second swing arm extend forwardly from a joined swing arm. The cylindrical axle support is coupled to a rear of the joined swing arm. A first chassis mount hingedly couples the first swing arm to the vehicle chassis. A second chassis mount hingedly couples the second swing arm to an articulated mount which is configured to couple the second swing arm to the vehicle chassis. The articulated mount cooperates with the first second swing arms to change the camber of the wheel, such that a tracking of the wheels remains substantially unchanged during traveling over rough terrain.

An axle suspension has an axle support mounted in a swivel so as to rotate about an axis of rotation and a steering lever that is connected with the axle support in torque-proof manner and can be pivoted about the axis of rotation. The axle support accommodates at least one wheel axle and is mounted so as to be displaceable relative to the axis of rotation, in the wheel axle direction, on an adjustment path.

A method and apparatus for building a fuselage assembly for an aircraft. A number of fixtures may be drive across a floor to an assembly area to form an assembly fixture. The fuselage assembly may be built on the assembly fixture.

A utility vehicle including a frame, a body supported by the frame, a seating area supported by the frame, front and rear ground engaging members supporting the frame and the body, and a powertrain drivingly coupled to the front and rear ground engaging members. The powertrain includes a transmission and an engine having a plurality of cylinders. The engine includes an intake manifold, a throttle valve, and an exhaust. The intake manifold and throttle valve are positioned longitudinally forward of the plurality of cylinders and the exhaust is positioned longitudinally rearward of a forwardmost portion of the plurality of cylinders.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

A rotary shock absorber for a vehicle and a pneumatic spring, in particular for a rotary shock absorber, are disclosed. The rotary shock absorber for a vehicle comprises a first component and a second component, wherein the second component is rotatably arranged relative to the first component. The rotary shock absorber comprises a pneumatic spring that is adapted to provide an elastic force F against rotation of the second component relative to the first component. The second component forms a pneumatic cavity of the pneumatic spring. The second component forms a hydraulic cavity of the pneumatic spring. The hydraulic cavity comprises a toroidal section.
