AI Technical Summary

Problems solved by technology

The current will increase the temperature of the collector head, and the high temperature phenomenon will easily soften and deform the rotating parts
Moreover, due to the sliding friction of the rotating parts when they rotate, under the action of current, electric sparks are likely to be generated between the relatively sliding surfaces, which will cause damage to the rotating parts

Abstract

The invention discloses a trolley head. The trolley head comprises an insulated fixing piece, a conductive piece, a rotating mechanism, a sliding seat and an electric connecting piece. A longitudinal shaft sleeve and a trolley pole fixing part are arranged on the insulated fixing piece; the conductive piece is arranged on the insulated fixing piece; and the conductive piece is not in contact with the longitudinal shaft sleeve. The rotating mechanism comprises a longitudinal shaft; the longitudinal shaft is inserted in the longitudinal shaft sleeve; the sliding seat is arranged on the rotating mechanism; and the sliding seat is made of a conductive material. The conductive piece is electrically connected with the sliding seat through the electric connecting piece. According to the trolley head disclosed by the invention, a conducting current formed on the rotating mechanism can be avoided; deformation and damage of the rotating mechanism can be prevented; the reliability of the trolley head can be enhanced and the service life of the trolley head can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of trolley buses, and relates to a power system of a trolley bus, in particular to a structure of a trolley bus collector. Background technique [0002] Trolleybus is a common transportation vehicle, which has the advantages of no pollution, low noise and high stability, and is widely used in cities with well-developed public transportation. Because trolleybuses usually need to continuously obtain power from the outside to ensure normal operation, the top of common trolleybuses is equipped with a power collection system. The current collecting system usually includes a collecting rod and a collecting head, and the collecting rod raises the collecting head so that the collecting head contacts the aerial cable above the road surface, thereby providing power for the trolleybus. [0003] Since the electric car often needs to merge and turn when driving on the road, its traveling direction cannot always be kept ...
