Abstract
A carriage, driven along a carriage rod, rests on the carriage rod at carriage V-bearings. The V-bearing connection is open at the bottom. A magnetic preloader applies a magnetic force biasing the carriage toward the carriage rod. A roller coupled to the carriage runs along a track surface away from the carriage rod. At high slew velocities, a local discontinuity, such as a bump, encountered by the roller causes an acceleration of the roller away from the track surface. The upward rotation causes a torque rotating the carriage around the carriage rod. A magnetic restoring torque is applied in the vicinity of the roller to keep the roller running smoothly along the track surface.
