Highway-vehicle system with improved braking, enhanced stability and provisions for electric power take-off
First Claim
1. A highway-vehicle system, comprising:
- (a) a structure which defines a narrow slot and an elongated cavity with vertical sidewalls, the cavity being substantially wider in transverse cross-section than the slot, the slot communicating with the cavity and extending upwardly therefrom to the highway surface; and
(b) a projecting member which is mounted on the vehicle and is suspended downwardly therefrom, the projecting member having elongated support arms which are insertable into the slot;
the support arms having stabilizing means and braking means pivotally connected thereto which, after the support arms are inserted into the slot, are rotated into proximity with the vertical sidewalls;
the stabilizing means and braking means being positioned, during use, so as to engage the vertical sidewalls below the slot.

Abstract
A highway-vehicle system for high speed travel which comprises a below-ground structure defining a cavity and a narrow slot extending upwardly therefrom to the roadway surface. Each vehicle in the system is equipped with a projecting member which, in its folded configuration, can be lowered into the slot. The projecting member includes a pair of stabilization wheels and a pair of hydraulically or pneumatically-actuated brake shoes. Once the projecting member has been lowered into the cavity, the wheels automatically unfold, so that they assume horizontal positions and press against opposing sidewalls of the cavity. With the wheels so deployed, the vehicle can be safely driven during high speed cornering and under windy conditions. The wheels can also be used to automatically steer each vehicle. In addition, the wheels are used to conduct electricity in the cavity sidewalls as part of the power takeoff for an electric vehicle. Like the wheels, the brake shoes also unfold once the projecting member enters the cavity. When braking is needed, hydraulic or pneumatic cylinders attached to each brake shoe press the shoes against the cavity sidewalls. Since the cavity is shielded from the weather, the brakes are kept dry for maximum braking efficiency. This system not only can be used in situations in which each vehicle is driven independently but also can be easily upgraded for computerized vehicle travel.
