  • Patent number: 6227120
    Abstract: An amusement ride vehicle capable of generating a natural “wheelie” motion with minimal acceleration is provided. Air springs are used to balance the vehicle about a predetermined center of gravity after passenger loading. The amount of balancing required is minimized by using a link, such as a pivoting control arm, to connect the front wheels of the vehicle to the front end of the chassis, thus enabling the chassis to be automatically balanced independent of the weight of the front wheels, without the need for computer control. Upon acceleration of as little as 0.5 Gs in a forward direction, the front end of the chassis rises smoothly and naturally into a upward arc while the front wheels remain engaged with the trackway. The amount of upward movement is limited by the length of the control arms, and can be further limited using stops, such as jounce and rebound bumpers.
