Compact Wheel Direct Drive for EVs
IEEE Industry Applications Magazine, 1996Concerning the application of slotless axial-flux PM motor (AFPMs) in electric vehicle drives, this article deals with the development of a 16-pole AFPM prototype which is used in the propulsion system of an electrical scooter. The proposed AFPM prototype has 45 Nm peak torque and 6.8 kg mass of active materials, and it is coupled directly to the ...

Comparisons on the Mechanics of Six-wheeled Drive and Four-wheeled Drive Prime Mover
The Planter, 2002An initial attempt was made to investigate the possibility of designing and developing a multipurpose, all terrain six-wheeled prime mover for the oil palm plantation in Malaysia. Comparisons were made on the mechanics of the six-wheeled drive with the commonly used four-wheeled drive prime mover in varied stimulated terrain conditions.

SAE Technical Paper Series, 1930
<div class="htmlview paragraph">ENGINEERING considerations leading to the former almost universal practice of steering with the front wheels and driving and braking with the rear wheels are reviewed, and the desire for bodies lower than can be made with conventional design is given as the main reason for the present interest in front drives.

In-wheel brushless DC motor for a wheel chair drive
2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010A gear-less drive for a wheel chair based on brushless DC motor is presented. The motor has external rotor equipped with neodymium-based permanent magnets and the inner stator is attached to the wheel axle. The performance of the motor is determined using three-dimensional FEM modeling. They are validated by the experimental measurements carried out on

Four-Wheel Drives for Six-Wheel Chassis
SAE Technical Paper Series, 1929<div class="htmlview paragraph"><b>M</b>ANY interesting problems in design are presented in the application of four-rear-wheel drive to a six-wheel vehicle. As axle design is intimately related to the rest of the chassis construction, the axle builder is concerned with the type of spring mounting, the method of taking the torque, and ...

Preview of Driving Surface Unevenness in Wheeled Mobile Driving Simulators
2018 21st International Conference on Intelligent Transportation Systems (ITSC), 2018Wheeled Mobile Driving Simulators (WMDS) have a theoretically unlimited range of motion and therefore bear a high potential for the simulation of complex driving scenarios. Vertical excitations due to non-perfectly even ground are one of the main challenges concerning the concept.

Vibrations in All-wheel Drives
ATZ worldwide, 2015The charging of internal combustion engines leads to a higher rotational irregularity of the torque output. This nonuniformity can stimulate the downstream drivetrain vibrations. This is, particularly rotational oscillations have been found to be relevant to the acoustic behaviour inside the vehicle.

Four-wheel drive or rear-wheel drive for high power farm tractors
Journal of Terramechanics, 1968Abstract The paper considers the relative merits of two or four wheel drive for agricultural tractors. It is based on a set of typical tyre performance characteristics obtained on four types of agricultural soils ranging from dry loam to wet clay loam.

ALL-WHEEL AND FOUR-WHEEL-DRIVE VEHICLE SYSTEMS
SAE Technical Paper Series, 1995<div class="htmlview paragraph">The purpose of this paper is three fold: to serve as a tutorial for engineers new to the field of drivetrain; to function as a reference manual for those who wish to retrieve some information on a topic they have not visited for some time; and to show the direction that four-wheel-drive technology should be taking.&
