摘要:
A power or current collector of an aerial trackway vehicle has an arm which is movable in accordance with the change of displacement of the current carrying cable with respect to a trackway by which the vehicle is suspended. A speed controller which is sensitive to the movement of the arm controls the speed of the vehicle and/or other vehicular functions.

A sensor arrangement features a rolling element and cam groove arrangement which induces a displacement via which a switch may be closed to indicate that torque is being applied via a steering wheel to an upper section of a steering shaft arrangement and which provides an essentially instantaneous drive connection between the upper and a lower section of the steering shaft arrangement thus maintaining a desirable degree of torsional rigidity.

A vehicular power steering system has on/off control means for controlling a hydraulic fluid pump in accordance with steering effort applied on a steering wheel. On the other hand, a sensing means senses vehicle speed. Judging means is connected with the on/off control means and the vehicle speed sensing means, and produces an actuating signal when the control means produces a control signal to drive the fluid pump and at the same time the sensed vehicle speed is below a predetermined speed. A solenoid valve is connected with the judging means. The solenoid valve is arranged to open and close a bypass passage which allows an air fuel mixture to bypass a throttle valve for an intake air flow control of the engine. Thus, the supply of an air fuel mixture to the engine is increased in response to the actuating signal, and the engine idling speed is stabilized.

A vehicle suspended from a trackway of an aerial trackway system is provided. The vehicle comprises a front traction unit having a supporting wheel and a rear traction unit having a supporting wheel. These traction units support a vehicle body of the vehicle and are rotatable relative to the vehicle body such that the supporting wheels may follow the trackway without slip. Apparatus is provided for linking the front and rear traction units such that a moment at the center of gravity of the front traction unit about its axis of rotation relative to the vehicle body and a moment at the center of gravity of the rear traction unit about its center of rotation relative to the vehicle body are balanced.

A guide arm is mounted via a ball joint to a support structure. A guide linkage, connected to the arm and foldable at its mid point, is also connected by a ball joint to the support structure. A second guide linkage guides the arm to a near vertical storage position when a motor folds the first linkage.
摘要:
A cable holder device for holding current-carrying cables spaced apart but biased to maintain contact with two current-collecting shoes. The shoes are mounted on a self-propelled cable car having an electric drive motor connected to the shoes and driven apparatus constructed as a driven pulley for suspending the cable car on a suspension cable from which the cable car is suspended and on which it travels. The holder maintains positive contact between the current-carrying shoes and the current-carrying cables regardless of the swaying of the cables and the cable car.
