摘要:
A snow plough arrangement comprising a least one snow plough unit and related to a system for driving an electrically propellable vehicle along a roadway. The vehicle has three sources of power: a vehicle-related power generator, a set of batteries and vehicle-external electric stations. The vehicle is provided with a current collector which is displaceable up and down and sideways in relation to the direction of transportation, in order to be brought into mechanical and electrical contact with elongated tracks positioned below the roadway and comprising a conductor adapted to be connected with an electric station. The snow plough unit is rotatably fastened to the contact means in an upper area thereof about a horizontally oriented axis of rotation and adapted to clear loose obstacles from the track and yield to solid obstacles. The snow plough unit and the axis of rotation are movably disposed in a vertical direction by means of a resilient member. The snow plough unit comprises a forwardly directed edge portion oriented in the direction of travel, the edge portion comprising a point, which may be brought into contact with the bottom of the track and/or the conductor.

The present invention relates to a transportation system using an electric automobile. The transportation system using the electric automobile comprises the electric automobile and an electricity-supply unit which supplies electricity to the electric automobile. The electric automobile charges a battery included when the electricity is supplied from an external source in motion, using some or all of the electricity and is driven by the electricity of the battery when the electricity supply to the automobile in motion is stopped.

A device is described with which electrical energy can be transferred from a power cable running along a stationary rail of a transport system to a moving element that can be driven along the rail. Each moving element has for this purpose a transfer head which works inductively together with the power cable. The power cable is attached with the aid of carrier profile which extends substantially along the entire length of the rail and is fixed in a releasable manner to the rail, which element has at least one a trough-like holder open to the side in which the power cable is laid. The power cable is thus relatively easily and accurately laid, avoiding hanging loops of cable which could be damaged by abrasion by the passing transfer heads of the moving elements.

A machine for laying a catenary cable or a contact wire of an overhead line extending above a track comprises a machine frame supported on undercarriages for mobility along the track, a storage drum mounted on the machine frame and carrying a reel of the catenary cable or contact wire to be paid out from the storage drum, and a guiding device for the paid-out catenary cable or contact wire. The guiding device is pivotable about a horizontal axis extending in the longitudinal direction of the machine frame and comprises a supporting mast having a longitudinal axis, a guide roller mounted to the supporting mast and arranged to be engaged by the paid-out catenary cable or contact wire, a drive for vertically adjusting the guide roller, and a drive for pivoting the guiding device about the horizontal axis. The guide roller is designed for adjustment relative to the supporting mast in a direction extending perpendicularly to the longitudinal axis thereof and transversely to the longitudinal direction of the machine frame, and a drive is provided for transversely adjusting the guide roller relative to the supporting mast.
摘要:
A transportation system for use with a roadway including conductive sections on the roadway so that electric vehicles having contact members thereon may contact the conductive sections. The sections extend in the direction of travel along the roadway and have spaces therebetween and the vehicle has at least three contact members spaced on the vehicle so that at least two of the contact members are always in contact with oppositely poled sections with unidirectional current flow means between each conductor and the motor.

A conductor rail is made of an aluminum conductor bar covered with a stainless steel contact cap. The cap is pressed against the top of the conductor bar during assembly and is permanently clamped to the bar by integral ears deformed over and down onto doubled over edges the side legs of the contact cap, holding the outer legs of the contact cap in tension, holding the cap against the top of the conductor bar.
摘要:
A fluid levitated generally convex support member particularly useful in supporting a pallet, plate or belt such that the pallet, plate or belt load may be moved in an air powered track system, the system including at least one concave track with means for supporting and guiding the convex member and the pallet, plate or belt thereabove on a thin film of pressurized air jetting from nozzles in the track. The support member includes a generally tubular, flexible and partly deformable outer member and means for internally stressing the outer member so that under load there will be controlled deformation thereof. The deformed member will be closely complementary to the track surface to maximize load carrying capacity while minimizing fluid support power requirements and the detrimental effect of track deformities. Of particular significance is the ability of the support assembly covering to vibrate at high frequency at the track surface in response to the track jets and the wedge flow of the fluid support film to provide a pumping action which propagates and augments the pressure of the support film. Also, the small air film provides a controlled air gap which permits the use of electromagnetic propulsion means installed as part of the track for reaction with suitable secondary devices included in the support member. Under load removal there will be controlled recovery of the shape of the outer member. The support member exhibits excellent wear, cleanliness, cushioning, manufacturing, and select frequency response and damping characteristics.
