Abstract:
A self-propelled amusement-park vehicle, adapted to ride on a pair of running rails and to drive itself on a drive rail located between the running rails, has a pair of units each comprising a rubber drive wheel engaging a respective lateral face of the drive rail, and mounted on an upright shaft which is connected at its upper end via a right-angle drive to the drive motor of the vehicle. Each drive unit is pivotal about an axis extending generally parallel to the drive rail which is parallel to the normal direction of travel of the vehicle, and a spring is provided which urges the lower end of the shaft mounting the wheel toward the drive rail so that the wheel is pressed against the respective face of the drive rail. The spring urging the drive wheel into engagement with the drive rail is received in a hollow shaft constituting the pivot axis for the support wheels. The vehicle has in each corner a pair of hyperboloidal support wheels which ride on the running rails of the system. Each pair of such wheels is mounted in a support which pivoted about the respective hollow shaft on the housing of the vehicle.
