The invention discloses a current collector which comprises a current collecting sliding shoe, a rocker arm and an elastic component. The current collecting sliding shoe is used for being in sliding fit with a supply rail, one end of the rocker arm is used for being hinged to a bogie framework, the other end of the rocker arm is hinged to the current collecting sliding shoe, and the elastic component is arranged between the rocker arm and the bogie framework so as to adjust contact pressure between the current collecting sliding shoe and the supply rail. The current collector further comprises an auxiliary rocker arm parallel to the rocker arm. The auxiliary rocker arm is hinged between the current collecting sliding shoe and the bogie framework, and the distance L12 of hinge points of the rocker arm is equal to the distance L14 of hinge points of the auxiliary rocker arm. Compared with the prior art, the characteristic of translation of the current collecting sliding shoe hinged to the rocker arm and the auxiliary rocker arm during rotating of the rocker arm and the auxiliary rocker arm of a parallelogram mechanism at the same angular speed is utilized, the problem of current collecting instability of the current collector caused by eccentric wear of the current collecting sliding shoe is solved, and train working safety and stability can be guaranteed. On the basis, the invention further discloses a rail transit vehicle comprising the current collector.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit vehicle and a current collector thereof. Background technique [0002] With the development of my country's urbanization process and the rapid expansion of central cities, urban rail transit represented by subways and light rails has been listed as key construction projects in major and medium cities. Compared with overhead catenary, steel-aluminum composite contact rail (or conductive Rail, third rail) power supply system has the advantages of long service life, reliable operation, less and easy maintenance, easy management, small power loss and beautiful appearance, so it is adopted by more and more design units and users. More and more attention has been paid to the current collector as a matching contact rail to ensure the reliability of vehicle power supply and operation. [0003] The current receiver refers to a set of dynamic current receiving equipment...
