摘要： A tracking device includes an external member and an internal member rotatable relative to the external member. A motor is attached to the internal member and includes a rotor shaft attached to the external member. A pair of target sensors that sense a phenomenon such as a magnetic field, sound, light or RF radiation, provide input to a controller that controls rotation of the motor. Angular acceleration of the internal member will cause an equal and opposite angular acceleration of the external member and the tracking device will roll toward the target. The tracking device may hop by suddenly stopping the rotation of the internal member or by suddenly decreasing or increasing the acceleration of the motor or by inserting a linkage fixed to the external member into the rotation path of the internal member.

摘要： An omni-directional wheel for an omni-directional vehicle that exhibits constant ride height, low vibration, and reduced maximum ground contact pressure is disclosed. The invention consists of a wheel assembly rotatably connected to the omni-directional vehicle chassis. The wheel assembly includes a hub on which free spinning rollers are rotatably mounted at an angle to the wheel axis. Constant ride height and low vibration operation are accomplished by configuring the rollers with an exterior profile, thickness, material properties and surface grooving to achieve constant deflection of the roller contact surface at all wheel rotation angles.

摘要： A vehicular snow ski steering keel bar having a recessed surface portion extending at least partially along the length in the side surfaces of the bar. A lower side surface portion below the recessed surface portion includes lateral extensions extending beyond the recessed surface potion to collect and/or compact snow and/or material coming in contact with the steering keel bar. An upper side surface portion has lateral extensions that further direct snow into the recessed surface portion during turning and cornering of the bar. The cross-sectional shape of the bar includes a basic hourglass shape with curved and/or flat surfaces. Various cross-sectional shapes can be used along the length of the bar to fine-tune the turning characteristics of the steering keel bar. Different configurations or shapes can be utilized for the sides of the bar to vary the turning characteristics between left and right turns.

摘要： A drive for a vehicle traversing rough terrain including first and second drive units and first and second pairs of tires. The first drive unit includes a first differential and axle. The second drive unit includes a second differential and axle. A secondary drive shaft synchronizes the second and first differentials. Each tire is divided into first and second segments. The center of the first segment is the rotational center of the tire so as to allow it to roll when in contact with the rough terrain. The first segment extends 240° and the second segment extends 120°. The radius of curvature of the second segment is greater than that of the first segment so as to allow it to be only slightly curved and almost flat, and as a result thereof, pointed areas are formed that bite into, and allow the second segment to grip, the rough terrain.

摘要： In a transmission for a steerable drive wheel (4) of a forklift, which transmission is pivotable around a vertical axle (8) and contains a spur gear stage (24, 26) and a second reduction stage formed by a pinion shaft (28, 30) and a bevel wheel (36), the second reduction stage is designed as hypoid wheel set (30, 36) with positive axle offset. Unlike the designs known already, it is hereby possible, by adhering to preset limits of the outer dimensions and a preset reduction ratio, to obtain a toothing of more supporting capacity and a thicker pinion shaft (28) so that the loads of the tooth flanks are canceled and it is possible to use a design of a high loaded pinion bearing (34) having more supporting capacity.

摘要： A class of transporters for carrying an individual over ground having a surface that may be irregular. Various embodiments have a motorized drive, mounted to the ground-contacting module that causes operation of the transporter in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered. Methods of controlling the transporter are described that allow the dynamic behavior of the transporter to more closely match preferences of a rider. These methods include providing preferential responsiveness to change in pitch angles and pitch rates.

摘要： A propulsion system for a vehicle comprised of two wheels, both of which are in the shape of hemispheres. Each of the hemisphere wheels is mounted through a bearing on a fork with two pivots attached to the inner race of the bearing, allowing the wheel to rotate around two perpendicular accesses. The center of each wheel is attached to the shaft through a double universal joint or a flexible shaft. By rotating the hemisphere wheel around the fork pivots the diameter of the wheel engaged with the ground is increased or decreased allowing the vehicle speed and/or direction to very.

摘要： An all-terrain bicycle is comprised of a bicycle frame having a front and a rear fork to which is removably secured a front and a rear wheel. Each wheel has a circular rim which is interconnected to the hub by spokes. The rear wheel has sprockets secured to the central hub and which is interconnected to a driving sprocket by a chain or other such belt-like drive connector. Each of the rims is provided with a surface engaging support shoes assembly to provide support of the bicycle on a surface. Such bicycles are particularly useful for riding on soft and also irregular surfaces which are deformable such as sand, snow or the like.
