Abstract

An improved electrically operated transportation vehicle and an electrified roadway over which the vehicle may operate and which supplies electric current to the vehicle are disclosed, in which hot power lines are located overhead of vehicles and neutral lines are deposited on the surface of the roadway. In addition, a high voltage AC line, extending continually along the roadway, is separated from a segmented low voltage AC or DC line. An improved electrical pickup is also disclosed to facilitate engagement and disengagement of a vehicle from a power supply line.

Claims

1. An electrical vehicle transportation system, comprising:

1) an electrified roadway having at least one traffic lane, and at least one stationary electrical conductor means associated with the roadway and extending along and coextensive with the roadway, wherein each said conductor means comprising at least two conductive lines extending along said roadway, of which at least one said conductive line is disposed in an overhead location above vehicles on said roadway (overhead conductive line) and at least one said conductive line is disposed on the roadway (on-road conductive line),

2) a steerable electrically powered vehicle having wheels riding on said roadway for movement of said vehicle along and laterally of said roadway, comprising;

a. an electrical propulsion motor means,

b. a battery means,

c. an electrical pickup means, comprising a first electrical contact means on said vehicle contacting said overhead conductive line,

d. an eduction means, comprising a second electrical contact means on said vehicle contacting said on-road conductive line,

whereby said battery means is de-charged and said motor means operates on battery power when the pickup means is disengaged from said electrical conductor means, and said battery means is re-charged and said motor means operates on power from said electrical conductor means when the pickup means is engaged with said electrical conductor means.

2. The electrical vehicle transportation system as defined in claim 1, wherein said overhead conductive line is a hot line, which carries high voltage, and said on-road conductive line is a neutral line.

3. The electrical vehicle transportation system as defined in claim 1, wherein said electrically powered vehicle further comprises an outlet for re-charging said battery means with outside electrical power source.

4. The electrical vehicle transportation system as defined in claim 1, wherein said electrical pickup comprises at least one contacting head, at least one protrudable arm, at least one insulation sheath, at least one transmission wire, and moving means,

wherein said transmission wire transmits electricity from said contacting head to an electrical motor in a vehicle,
