ABSTRACT:
A vehicle includes a carriage suspended with wheels from an overhead track. A suspension mechanism supports a passenger or cargo car from the carriage. The suspension mechanism includes horizontal pivot joint that allows the car to swing about a horizontal axis when traversing bends. A sliding connection between the car and the pivot joint permits the car to displace horizontally relative to the pivot axis. A motor rotates a screw thread mechanism to produce such displacement. A sensor detects inclination of the car relative to vertical in response to uneven weight distribution or wind forces, but is not responsive to centrifugal forces and normal swinging of the car at bends. The sensed inclination of the car may be displayed on a monitor, and controls permit the motor to be actuated to displace the car in a direction in which gravity applies a torque to the car that reduces undesired inclination.
