Air bellow drive Valve unit ADD Coupling rod Parallel guide bar compl. Pan head Shock absorber Cable with terminals Overreach detection Insulator compl.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Base Frame The welded structure of the base frame is the basis of the pantograph. The component is coated for protection of environmental influences. The base frame is mechanically attached to the vehicle roof with insulators. The current is led from catenary to vehicle by the current connection at the base frame and the cabling from the vehicle.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Lower Frame The lower frame is a welded structure which is rotary mounted to the base frame. The component is coated for protection of environmental influences. The cams assure that the static contact force is constantly over the whole working range of the pantograph.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Upper Frame The upper frame is a welded structure made of steel tubes. The component is coated for protection of environmental influences. SB-038688_RS_Blatt1 Illustration 4: Upper frame All components of the Upper Frame are listed in the Spare Parts – List (...
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Air Bellow Drive The pantograph is raised with the air bellow drive. The air bellow drive is mounted between base frame and lower frame. The force of the bellow is transmitted by cables which are running in cams. The air bellow drive is connected with the valve unit ADD with a compressed air hose.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Valve Unit ADD The valve unit ADD (automatic dropping device) is used for monitoring the sliding strips to minimize damage of catenary and pantograph due to damaged sliding strips. If a sliding strip is damaged, a control pipe is opened and compressed air is releasing.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components ADD Activated The valve unit ADD is in ACTIVATED state when the pantograph is delivered. Therefore, monitoring of the sliding strips is enabled. D A N G E R Pantograph raised PNEUMATICALLY. Valve unit ADD responds, pantograph lowers.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components ADD Deactivated The valve unit ADD is in ACTIVATED state when the pantograph is delivered. Therefore, monitoring of the sliding strips is enabled. Activate ADD ( Chapter #4.2.5.1). A T T E N T I O N ADD ACTIVATED when performing leaking test.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Coupling Rod The coupling rod consists of a connection tube made of a stainless-steel round-tube and two bearing houses (equipped with grooved ball bearings) with left-hand-thread and right-hand-thread. By turning of the connection tube, the geometry of the pantograph will be adjusted and fine-tuned.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Parallel Guide The parallel guide bar prevents the pan head from distorting, while the pantograph is raised or lowered. The turning capacity of the pan head is adjusted by screwing-in and screwing-out the rod end of the parallel guide bar. This achieves equal wear on both sliding strips.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Pan Head The Pan Head is mounted onto a shaft, which in turn is located inside the cross tube of the upper frame. Leaf springs are used for the suspension of the sliding strips. The pan head springs (leaf springs) are affixed in the rocker boxes and they carry the sliding strips.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Shock absorber The shock absorber between lower frame and base frame compensates vibrations of the pantograph. The stages of compression and tension are designed to assure best contact behavior between sliding strips and catenary.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Cable with Terminals The cables with terminals consist of round braids with secured terminals at both ends. The cables are secured against twisting at these secured terminals when detaching / attaching cables. The cables with terminals are guided by the cable guide of the air bellow drive and at the cams of the lower frame.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Overreach detection The overreach detection is used to detect a lifting height. Function: The overreach detection is supplied with compressed air from the air bellow drive. When the lifting height is reached, the stop switches the 3/2-way valve and compressed air flows to the pressure safeguard.
Schunk Bahn- und Industrietechnik GmbH Pantograph Components Insulator The pantograph is mounted on supporting insulators. The supporting insulators provide the electrical insulation between the live pantograph and the roof of the vehicle.
