Abstract:
A vehicle is disclosed. The vehicle may include a base portion and a modular portion. The base portion may be a four wheel vehicle having an operator area with seating for at least two occupants in a side-by-side arrangement. The modular portion may be coupled to the base portion resulting in a six wheel vehicle. The wheels of the modular portion may be powered by an engine of the base portion.
Abstract:
An output transfer group is disclosed for use with a mobile machine. The output transfer group may have a housing, and an input yoke extending from the housing and configured to receive an input torque. The output transfer group may also have a first output yoke extending from the housing and configured to provide a first output torque, a second output yoke extending from the housing and configured to provide a second output torque, and a plurality of gears disposed within the housing and connecting the input yoke to the first and second output yokes. The output transfer group may further have a disk stack operatively connected to two of the plurality of gears, and an actuator configured to selectively compress the disk stack to vary a split of the input torque between the first and second output yokes. The actuator may be maintained in contact with the disk stack during operation of the output transfer group.
Abstract:
This patent discloses a climbing vehicle capable of high payload to weight ratio and capable of climbing surfaces with geometric variations and traveling along a single dimension. More specifically, this invention applies to a vehicle well adapted to climbing non-planar surfaces such as pipes or other structural members while traveling along a single dimension, for example traveling parallel to the axis of the pipe. The climbing vehicle makes contact with the climbing surface through drive wheels and a trialing arm. The adhering members are aligned with the primary axis and are rigidly attached or contained in a suspension that is able to conform to a large range of surface irregularities while providing push and pulling forces between the adhering members and the climbing vehicle chassis to uniformly distribute the climbing loads on the adhering members. The result is a climbing machine that can accommodate large surface irregularities while maximizing the climbing payload with a minimum number and size of adhering members.
Abstract:
An omnidirectional mobility apparatus. The current invention is an omnidirectional, remote-controlled mobility apparatus, similar to a wheelchair, which allows the transport of an individual or object(s). The device includes a cubic-shaped base with wheel wells on each vertical side of said base. Within each wheel well is a wheel set, such that the front and rear wheel sets face each other and the left and right wheel sets face each other. The circumference of each wheel set includes a plurality of transverse-facing, smaller wheels disposed incrementally within each wheel set along the circumference of each wheel set, such that a portion of the smaller wheels protrude outside the circumference of each wheel set. This allows the mobility apparatus to propel in any direction. Also included in the device are an adjustable, interchangeable footrest and chair assembly.
Abstract:
A multi-unit mobile robot comprising a plurality of separate carriages or units linked together by linkages. Each unit comprises hinged first and second segments which facilitates pitch relative motion between the segments, and accordingly the units. By controlling actuators to the hinges, one can cause the robot to coil around and compress against the exterior, or compress against the interior, of an object to be traversed. The linkage between mobile units facilitates at least one of lateral pivot or yaw relative motion between units, and optionally roll.Each hinged platform is carried by a pair of Mecanum wheels, which facilitate movement of the unit in any direction. Preferably, alternating units are of differing widths, and the wheels on the units are sufficiently large that they capable of overlapping, thereby enabling the robot to navigate very sharp edges or corners in the surface of an object being traversed by the robot, with the wheels always maintaining contact with the surface being traversed.Among other possible uses, the multi-unit mobile robot can be used to service windmill blades and towers, and carrying cargo up and down windmill towers by directing a multi-unit mobile robot to wrap around the and traverse the tower.
Abstract:
A drive axle assembly is provided that improves lubrication to the components of the drive axle assembly. As the wheel differential rotates, lubricant is splashed and lubricates bearings and other associated components of the differential assembly. In addition, lubricant is pumped by rotation of the first and second spur gears and is fed to the radial face of a forward bearing through a lubrication passage through a plurality of passages.
Abstract:
A floor curing apparatus is disclosed, including a housing, an ultraviolet lamp, and an offset wheel arrangement including a pair of inner drive wheels configured to rotate and alternately be driven about a first common axis and a pair of outer drive wheels configured to rotate and alternately be driven about a second common axis. Each of the pair of outer drive wheels are positioned a first predetermined distance outward from each of the pair of inner drive wheels, and the first axis is offset from said second axis by a second predetermined distance. The floor curing apparatus also includes a shutter device a linear actuator configured to drive a support element in a direction away from the ultraviolet lamp, the support element affixed to a plurality of rods configured to draw the shutter device away from the ultraviolet lamp.
Abstract:
A method of operating a transmission device comprising at least one input shaft and at least two output shafts. Torque that is present at the input shaft can be distributed between the two output shafts with a variable degree of distribution which can be changed according to the operating state depending on a transmission capability of at least one shift element. When a request to set a predefined degree of distribution is received, a mechanical self-locking torque of the transmission device—which influences the degree of distribution between the output shafts and is dependent upon the torque present at the input shaft—is determined, and a difference between the mechanical self-locking torque and a target overall locking torque of the transmission device that is equivalent to the required degree of distribution is determined. The transmission capability of the at least one shift element is set depending on this difference.
Abstract:
The device for crossing obstacles for a motorized vehicle includes a chassis connected to n (n≧3) wheels on each side, and a driver suitable for rotating the wheels. Each side of the chassis includes a mechanism comprising n−1 arms hingedly connected two-by-two about a shared pivoting axis on which the n wheels are distributed, respectively a front wheel, n−2 intermediate wheels, and a rear wheel. The mechanism allows each wheel to pivot relative to the axis of each adjacent wheel.
Abstract:
An omni-directional wheel assembly for a vehicle that includes a wheel, at least one lower suspension link and an upper attachment joint. Both the at least one lower suspension link and the upper attachment joint are attachable to the vehicle. The wheel is able to rotate at 360°, to steer the vehicle, around a pivot line positioned by the at least one lower suspension link and the upper attachment joint once attached to the vehicle. A projection of the pivot line onto a vertical projection plane comprises a vertical axis passing through a contact point between the wheel and ground defining a caster angle with the vertical axis, where whatever the orientation of the projection plane, the omni-directional wheel assembly includes an adjustment means able to adjust the caster angle within a predetermined range.
