The invention discloses a trolley
bus power receiving
system, wherein the lower end of a lower arm rod is articulated with a
chassis, and the upper end is articulated with an upper arm rod; an upper end of that tie rod is articulate with a lower end of the upper arm rod; a bow head charger is arranged at the upper end of the upper arm rod; It also includes a
force transducer and a
balance spring.One end of the
balance spring is hinged with the force transmitting member, and the other end is fixed on the
chassis; a low end of that tie rod is articulated with a force transmit member, and the force transmitting member is articulate with a
chassis; the invention also comprises a ceiling arranged horizontally, a side
canopy arranged perpendicular to the ceiling, a power supply rail installed on the inner wall of the side
canopy, and a bow head charger slidable along the ceiling. Before the bow charger abuts on the ceiling, the force transfer member is balanced by the pull rod and the
balance spring, and does not rotate relative to the chassis. The invention requires low parking position accuracy of the driver, does not need to adjust the relative position of the bow head charger and the power supply rail, saves the
operation time, leaves more charging time, improves the efficiency of the vehicle entering and leaving the
station, and does not affect the appearance of the city.
