Various materials can be used to construct the vehicles in a QuickStick HT transport system.
Any material that is used must be able to carry the payload without deflecting while support-
ing the magnet array in the correct relationship to the motors. In general, use a lighter weight
vehicle to maximize the acceleration capability of the system for moving the payload.
Wheels or rollers are used to support the vehicles on the guideway while allowing the vehicles
to move freely upstream and downstream. They also maintain a consistent space between the
magnet array that is attached to the vehicle and the QSHT motors (Vehicle Gap). Wheel and
roller materials affect the frictional resistance, which affects the amount of thrust that is
required to move a vehicle. The selected material must be hard enough to provide a low roll-
ing resistance but, depending on the environment the system is used in, soft enough to mini-
mize excess noise when traversing the joints between guideway sections.
Vehicles can have one or two magnet arrays that are attached to the surface closest to the
motors based on the use of the vehicle and the design of the guideway. Typically, when vehi-
cles travel guideways with curves they have two independent magnet arrays to help maintain
maximum alignment of the arrays with the motors while traveling through the curve as shown
in
Figure 3-32 .
