Current collector i.e. trolley boom, for track-bound trolley bus, has contact shoe provided with wear reserve part, and support comprising advancing mechanism for implementing advancing movement of contact shoe

摘要

#CMT# #/CMT# The collector has a contact shoe (10) for producing electrical sliding contact with a contact line (F). A support (20) is provided for the contact shoe, and a connecting rod connects the support with a vehicle. A pressing unit for pressing the contact shoe to the contact line. The contact shoe is provided with a wear reserve part (V). The support comprises an advancing mechanism for implementing advancing movement (Z) of the contact shoe, where the advancing movement compensates wear of the contact shoe. #CMT#USE : #/CMT# Current collector i.e. trolley boom, for an electrically driven vehicle i.e. track-bound trolley bus. Can also be used for a rail-bound traction vehicle and a lorry with electrical or diesel electric drives. #CMT#ADVANTAGE : #/CMT# The contact shoe is provided with the wear reserve part, and the support comprises the advancing mechanism for implementing the advancing movement of the contact shoe, where the advancing movement compensates the wear of the contact shoe, thus realizing prolonged maintenance intervals of the current collectors while reducing overall maintenance costs of the current collectors. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a current collector with a support. F : Contact line V : Wear reserve part Z : Advancing movement 10 : Contact shoe 20 : Support.
