The Uni Wheel is intended to gain the advantages of individual wheel drive without having to mount the motor directly to, or inside, the wheel. Instead, it subsumes the functions of constant-velocity joints, drive shaft and reduction gearing into a single system within the wheel. [1] The system has a central sun gear, linked by two articulated ...
It featured two "Scorpion" anti-tank missiles, wheels that were heat and puncture resistant, and a rear-mounted anti-aircraft cannon. [14] In 1993, it was recast and released as the Dino-Hunter Jeep , as part of the Dino-Hunter Mission Playset, which also included repainted versions of the figures Ambush and Low-Light .
Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs (called rollers) around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems.
Flat-blade jeweler's screwdrivers and the tips found in 1 ⁄ 4-inch or 6.4-millimeter drive sets are generally hollow-ground. Note that it is this typical chisel shape which allows 9 screwdriver sizes to drive 24 different slotted screw sizes, with the drawbacks of not fitting as closely as a hollow-ground screwdriver would, and increasing the ...
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
HICAS (/ h aɪ k æ s /; High Capacity Actively Controlled Steering) is Nissan's rear wheel steering system [1] [2] which was fitted to cars from approximately 1985 to 2010, including models ranging from the Skyline (R31, R32, R33, and R34) and Fairlady Z (Z32) to smaller vehicles like the Nissan Cefiro (A31), Silvia (S13 & S15)/240SX/180SX and Nissan Serena/Nissan Largo.
This is easily accommodated when the wheels are not connected, however it becomes more difficult for the drive wheels, since both wheels are connected to the engine (usually via a transmission). Some vehicles (for example go-karts and trams ) use axles without a differential, thus relying on wheel slip when cornering.
The purpose of four-wheel drive is to maintain optimal traction when manually selected. A vehicle has four-wheel drive when the front and rear driveshafts can be locked together to move at the same speed and send the same amount of torque to all four wheels. [5] Several four-wheel-drive vehicles have been built without a drive shaft between the ...
