Description
technical field [0001] The invention belongs to the technical field of charging systems for rail vehicles, and in particular relates to a current receiver and a rail vehicle. Background technique [0002] The current collector is usually installed on the bogie of the rail vehicle to dynamically take current from the rigid power supply rail for the rail vehicle to meet the power demand of the rail vehicle. [0003] For existing receivers, refer to the attached figure 1 , including cylinder 2, swing mechanism and sliding shoe 4. The swing mechanism includes a main swing link 31 , an auxiliary swing link 32 , an adapter seat 33 , a swing link support 34 and an extension spring 1 . The main swing link 31, the auxiliary swing link 32, the adapter seat 33 and the swing link support 34 form a four-bar linkage mechanism. Auxiliary fork 32 has auxiliary fork crank, one end of extension spring 1 is connected on the auxiliary fork 32 of auxiliary fork 32, and the other end is fixed ...
