Abstract:     The present invention provides an amusement ride having a self-propelled electric powered ride vehicle capable of maximum acceleration of about 0.3 to as much as about 1.1 G's in either direction using a unique pinch wheel drive system, and including an on board vehicle controller and peripheral equipment for controlling the vehicle. The pinch wheel drive system, which compresses driven wheel motor packages against a tractive surface, generates compression using a system which is independent of the vehicle's weight and motion. A master controller is provided for ride systems having multiple self-propelled vehicles on the same track for communicating with and coordinating the movement of the ride vehicles. This allows precise control of multiple ride vehicles to allow faster dispatch and shorter intervehicular spacings by implementing a floating zone control. Electric power compatible with the on board propulsion and controllers can be provided to the ride vehicles in a conventional manner using an electric bus bar mounted along the track. A ride vehicle of the present invention is capable of generating thrills not previously available in conventional roller coaster or powered vehicle rides, such as the ability to apply reverse propulsion and generate high performance maneuvers in reverse. Additionally, the pinch wheel drive system of the present invention provides the ability to generate electricity during deceleration or while coasting down hill. This enables the master controller to space ride vehicles so that some are consuming electricity while others are generating electricity, thus providing a highly efficient and economical ride. Further, because of the high accelerations possible, equivalent or superior thrill can be obtained using tighter horizontal curves and shorter hills, enabling use of a track having a smaller footprint than is possible using conventional components.

First Claim:
Show all 54 claims
What is claimed is:     1. A high performance amusement ride having a self-propelled ride vehicle capable of maximum acceleration of between about 0.3 G and about 1.0 G in either a forward or reverse direction, said amusement ride comprising:
  • a track having two substantially parallel, spaced apart load bearing rails and a substantially continuous drive fin mounted along said load bearing rails, said drive fin having a first and a second vertical tractive surface, said first and second tractive surfaces being substantially flat and substantially parallel to each other, said track being provided with at least one vertical, horizontal, or compound curve;
  • an electric power source disposed along said track; and,
  • at least one vehicle mounted for movement-along said track, said vehicle including
    • a frame,
    • at least one passenger compartment attached to said frame,
    • a plurality of load bearing wheels for engaging said load bearing rails of said track,
    • an electric pinch wheel drive for engaging and accelerating the vehicle above 0.3 G along the drive fin, said electric pinch wheel drive including
      • a first electric drive motor package pivotally mounted to said vehicle to engage said first tractive surface of said drive fin, a second electric drive motor package pivotally mounted to said vehicle to engage said second tractive surface of said drive fin, each said drive motor package having an electric motor with a motor output shaft which can rotate with substantially equal performance in either a clockwise or a counterclockwise direction, a transmission means for reducing the speed of the motor output shaft, a wheel attached for rotation to a transmission output shaft, said wheel including a tire for engaging said tractive surface,
      • a compressive coupler for simultaneously compressing the tire of the first electric drive motor package against the first tractive surface and the tire of the second electric drive motor package against the second tractive surface with sufficient force to enable the electric drive motor packages to move the vehicle along the fin, whereby the amount of compressive force generated by said compressive coupler is substantially independent of vehicle weight; and,
      • a motor controller electrically connected to each said motor for controlling the direction and speed of each motor output shaft;
  • a vehicle controller for determining the position of the vehicle on the track and for communicating with and controlling the motor controllers; and,
  • a conductor for drawing electrical power from the electric power source and delivering said electrical power to said electric drive motor packages, said motor controllers, and said vehicle controller.
