The invention discloses a bogie for a rail vehicle, the rail vehicle and a rail transit system. The bogie comprises an axle assembly, a straight first push rod and two straight second push rods, wherein one end of the straight first push rod is rotationally connected with the axle assembly, and the other end of the straight first push rod is rotationally connected with the vehicle body; one end ofeach straight second push rod is rotationally connected with the axle assembly, and the other end of each straight second push rod is rotationally connected with the vehicle body; elastic pieces arearranged at the rotating connection position of the straight first push rod and the axle assembly, the rotating connection position of the straight first push rod and the vehicle body, the rotating connection position of the straight second push rod and the axle assembly and the rotating connection position of the straight second push rod and the vehicle body. According to the invention, a traction mechanism of the bogie adopts the three straight push rods, transverse displacement of the vehicle body of the vehicle relative to the bogie can be released, and the transverse stability of the vehicle is good.
