Charging knife assembly, charging equipment and rail vehicle

Abstract

The invention discloses a charging knife assembly, charging equipment and a rail vehicle. The charging knife assembly comprises a mounting bracket, a swing arm, a pivot shaft, a bushing and a chargingknife. The mounting bracket is provided with an assembly hole, the swing arm is provided with a pivot hole, the pivot shaft penetrates through the pivot hole to be arranged in the assembly hole, andthe swing arm can rotate around the central axis of the pivot shaft. The bushing comprises an annular elastic piece, the elastic piece can be elastically deformed, the bushing is arranged outside thepivot shaft in a sleeving mode and located in the pivot hole, the bushing is in contact with the inner wall of the pivot hole, and the charging knife is arranged on the swing arm. According to the charging knife assembly, the charging knife can rotate around the pivot shaft along with the swing arm. Therefore, the problem that the charging knife and a charging groove are not aligned due to assembly errors can be solved. Moreover, when the charging knife swings left and right along with the rail vehicle, the charging knife can be correspondingly rotated and adjusted through the pivot shaft, sothat the charging knife and the charging groove always keep surface contact, and the charging stability and charging efficiency of the rail vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a charging knife assembly, charging equipment and a rail vehicle. Background technique [0002] Rail vehicles usually use flexible catenary to take power, and use pantograph-catenary or shoe-rail contact charging. This power-taking method arranges power grids along the entire line, and the investment cost of power-taking methods is generally high. The development potential of transport electric locomotives is huge. [0003] In the related technology, the new energy vehicle adopts a groove on the road surface to charge the vehicle. The technical solution is actually a concave arc surface groove installed under the road surface groove, and the receiver is charged in contact with the arc surface groove. The contact effect between the charging current receiving contactor and the arc surface groove is poor, which affects the current receiving area, resulting in poor charging sta...
