Abstract
A bogie for a rail vehicle includes: two pairs of wheel sets arranged frontward and backward (51), axle boxes (52) respectively fixedly arranged at both ends of a central rotating shaft of the wheel set, and a frame arranged on two axle boxes on the same side (50), and further includes: a current collector mounting plate (53) that is fixedly mounted with a current collector, with both ends of the current collector mounting plate being respectively fixedly connected to the two axle boxes on the same side. In the bogie for the rail vehicle, the current collector is fixedly connected on the axle box, and thus has the same state of motion as the axle box, effectively reducing the displacements of the current collector in all directions relative to the third rail during operation, and reducing vibration and impact suffered by the current collector.
