Abstract: The invention is a drive system for rotating a wheel of an aircraft landing gear. The drive system includes a motor operable to rotate a drive pinion via a drive path, and a driven gear adapted to be mounted to the wheel. The drive system has a first configuration in which the drive pinion is capable of meshing with the driven gear to permit the motor to drive the driven gear via the drive path. The drive path has an input shaft having an axis of rotation spaced from an axis of rotation of an output shaft. The output shaft is operable to pivot about the axis of rotation of the input shaft. Also, an aircraft landing gear having a wheel and the drive system, where the driven gear of the drive system is mounted to the wheel.

Abstract: A system for providing control to a parking brake for an aircraft (10) having a power source includes a panel (28) accessible from an exterior of the aircraft (10) and a parking brake switch (32) disposed on the panel (28) providing control over the engagement and disengagement of the parking brake on the aircraft (10), a method operating such a system for providing control to a parking brake is also disclosed.

Abstract: A ground propulsion assembly for an aircraft includes an axle, a wheel rotatably connected to the axle, and a transmission. The transmission includes a housing mounted proximate the axle and a drive element disposed at least partially outside of the housing and operatively connected to a power input. A mounting bar extends between the axle and the transmission and a mounting bar first end is rigidly connected to the axle, and the transmission is pivotally connected to a mounting bar second end. A spring is disposed between the transmission and the axle and the spring is configured to urge the drive element out of engagement with the wheel. An actuator is operatively connected between the transmission and the axle, and is configured to selectively generate a force in opposition to the disengagement spring such that the drive element moves relative the wheel and operatively engages the wheel.

Abstract: A multi-vehicle arrangement for heavy haulage includes at least a first tractor unit mechanically connected with a second tractor unit, wherein each tractor unit forms a separately drivable tractor unit including a driver cab), a digital communication device, steering wheels, a braking system, and a power train comprising a power source, a friction clutch, and an automatic transmission, where the friction clutch is arranged to be disengaged or engaged for drive torque transmission from the power source to the automatic transmission, a digital communication link is provided between the tractor units by the digital communication devices, and a control system of the first tractor unit is arranged to control at least a clutch load of the friction clutch of each of the first and second tractor units for the purpose of reducing the risk of over-heating of any of the friction clutches during engagement or disengagement of the friction clutches.

Abstract: A grain cart capable of self-propulsion and receiving steering and propulsion inputs from a lateral extendable connector to a tractor for the grain cart so that the grain cart may be deployed close to the central chassis of a combine for unloading of grain.

Abstract: An aircraft tug includes a tow bar which extends from a chassis, the tow bar operable to autonomously attach with an aircraft main landing gear assembly and transfer electrical power therebetween.

Abstract: A reverse drive mechanism is configured to rotate at least one wheel of a multi-wheeled device in a reverse direction so that the device moves in that reverse direction. One particular application involves a motorcycle conversion assembly in which at least one of the rear wheels of the conversion assembly is driven in the reverse direction so as to back-up the motorcycle.

Abstract: An articulated vehicle is made up of two independently moveable vehicle bodies, for instance tracked vehicle bodies. The first vehicle body has an engine and the second one has a motor/generator. An articulation device connects them to allow the first vehicle body to drive the second vehicle body or vice versa or even for them to act together. A drive transmission that can be used in the vehicle allows power to be input from two shafts or for one of the shafts to be an additional power output. An articulation device that can be used in the vehicle allows quick alignment and/or coupling and decoupling of the two bodies.

Abstract: A split-frame vehicle in which the front and rear sub-frames may rotate relative to one another along a longitudinal axis that runs generally parallel to the ground. In one embodiment, the vehicle includes a locking mechanism operatively coupled between the front and rear sub-frames. The locking mechanism is operative between a locked position in which the sub-frames are rigidly coupled and an unlocked position in which the sub-frames are free to rotate relative to one another. In a second embodiment, the vehicle includes an axial rotator joint connected between the sub-frames. The joint includes a first bearing plate connected to the front sub-frame and a second bearing plate connected to the second sub-frame. The faces of each bearing plate bear on one another and define the rotational interface between the sub-frames. A drive shaft extends through an opening in the center of each bearing plate.
