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.
本发明公开了一种用于轨道车辆的转向架、轨道车辆及轨道交通系统,转向架包括:车桥总成;直型第一推杆,直型第一推杆的一端与车桥总成转动连接,直型第一推杆的另一端与车体转动连接;两个直型第二推杆,每个直型第二推杆的一端均与车桥总成转动连接,每个直型第二推杆的另一端均与车体转动连接;直型第一推杆与车桥总成的转动连接处、直型第一推杆与车体的转动连接处、直型第二推杆与车桥总成的转动连接处、直型第二推杆与车体的转动连接处均设有弹性件。本发明的转向架的牵引机构采用三根直型推杆,车辆的车体相对转向架的横向位移可以得到释放,车辆的横向平稳性较好。
