A track installation for vehicles of a transport installation comprises a track supporting the vehicles at their vehicle carriages and possessing an inbound side and an outbound side for the vehicles. A conveyor is operatively associated with the track and contains entrainment members for entraining coaction with the vehicles. The track constitutes a generally or essentially horizontal track structure and extends along the complete length of the conveyor. Vehicle stops defining stop or parking positions for the vehicles are distributively arranged along the track. Each stop is provided with an actuation element and each stop or parking position has a vehicle sensor as well as an interrupter for disabling the entrainment of the there parked vehicle by the conveyor. The vehicle sensor of each stop or parking position is connected with the actuation element of the stop and also with the interrupter of the preceding or upstream located stop or parking position viewed in the vehicle conveying direction. Each interrupter is structured to act upon an entrainment connection between an entrainment member of the conveyor and a vehicle to disable vehicle conveyance.

Track installation for the vehicles of a transport installation,

The switching device which interconnects a substantially linear primary track with a curved branch track, wherein each such track possesses a travel rail and in a plane above each of the travel rails a guide track, comprises two pivotable or swivelable travel rail sections and a curved pivotable or swivelable guide rail section. The pivotable or swivelable travel rail sections are alternatively movable out of rest positions into travel positions in which such are located in recesses formed by stationary travel rail sections. The movable rail sections are mutually interconnected with one another and with an actuation rod by toggle levers or toggle joint structures and thus commonly actuatable. These toggle levers or toggle joint structures coact with abutments and enable locking the movable rail sections in their travel positions. The switching device affords quiet travel of the vehicles of the overhead cable transport installation and prevents derailing thereof.

Switching device for an overhead cable transport

At each station of the overhead cable transport installation the vehicles which have been released or unclamped from the conveying cable are decelerated or accelerated by pneumatic wheels. Between the V-belt drive and the hub of each pneumatic wheel there is arranged a free-wheeling clutch or slip coupling equipped with a pre-biased restoring or return spring. The free-wheeling clutch transmits in one direction the torque or rotational moment from the V-belt drive to the pneumatic wheel without play. In the opposite direction such free-wheeling clutch rotates against the restoring moment of the pre-biased restoring spring. As a result there is eliminated the slip and the resultant wear of the pneumatic wheels upon the friction plate with which they come into contact during such time in which two neighboring pneumatic wheels engage with the friction plate.
