Abstract

The double-wire powering trolleybus bow with damping spring barrel used in city public traffic includes bottom frame, lower arm rod, pull rod, upper arm rod, balance rod, head seat cross rod, cylinder, damping spring barrel, top cross rod, electrically conducting top sliding board, insulating seat, insulating rod and top spring. The six parts including bottom frame, lower arm rod, pull rod, upper arm rod, balance rod and head seat cross rod constitute two duplex planar quadric crank mechanisms with rods connected flexibly. The electrically conducting top sliding board is separated by the middle insulating rod into two current collectors fixed via the insulating seat on the top cross rod; and the top cross rod is connected flexibly to the head seat cross rod, with two ends being connected via the top spring. When the low arm rod is oscillated by the cylinder on the bottom frame via the damping spring barrel, the electrically conducting top sliding board will ascend or descend. The present invention has good contact performance, etc.

Description

technical field [0001] The invention relates to a trolley bus pantograph, in particular to a trolley bus double-wire receiving type pantograph with a spring damping cylinder, which belongs to the field of urban public transportation. Background technique [0002] At present, the trolley bus used for urban public transportation has the characteristics of low noise, no emission pollution, quick start and fast uphill, but due to the existence of overhead power supply contact wire network, roof collector pole and collector slipper, it makes the The tram cannot overtake the tram, and if there is an accident on the high-jump wire of the collector sliding shoe during driving, it will easily lead to traffic jams and affect the landscape above the city streets; the charging type trolleybus in the station area that uses large-capacity batteries or capacitors to store energy and stop for fast charging can Most of the overhead power supply catenary network is canceled, and only a specia...
