Problems solved by technology
However, as the railway continues to vigorously advance towards high-speed and heavy-duty directions, the wheel-rail relationship further deteriorates
When the locomotive is passing the curve, the locomotive body drives the frame to continue to maintain the original direction of motion due to inertia, while the wheelset is forced to run along the track due to the guiding effect of the track, especially the first axis has an angle of attack, and the wheel flange contacts the front of the tread contact, the wear of the wheel rim and the side of the rail increases, and the wheels are easy to climb the rails, so it is difficult to meet the needs of safe and smooth operation of the ever-growing locomotive

The invention provides a locomotive radial bogie mechanism and a railway locomotive bogie. A bogie shaft box is hinged to a frame through shaft box pull rods. The shaft box pull rods are symmetrical about the transverse center face of a locomotive and have a drift angle. Joints of the two symmetrically-distributed shaft box pull rods are correspondingly connected to form an isosceles trapezoid, and substantially, the frame, wheel pairs and the two shaft box pull rods form a four-link mechanism. Under the effect of the four-link mechanism, the wheel pairs are pushed to be located in the radialpositions, the interaction between wheel rails is reduced, the curve passing performance of the locomotive is remarkably improved, and the running safety and stability of the locomotive are improved.
Description
technical field [0001] The invention relates to the technical field of locomotive vehicle structure design, in particular to a locomotive radial bogie mechanism and a railway locomotive bogie. Background technique [0002] The harmonious high-power AC transmission electric locomotive independently designed and produced in my country uses pull rods for positioning the axle boxes. Its structure is simple, the longitudinal stiffness is large, and the transverse stiffness is small. It has been widely used due to its advantages such as mechanical performance, wheel-rail adhesion utilization, and improvement of locomotive dynamic curve passing. However, as the railway continues to vigorously advance towards high-speed and heavy-duty directions, the wheel-rail relationship further deteriorates. When the locomotive is passing the curve, the locomotive body drives the frame to continue to maintain the original direction of motion due to inertia, while the wheelset is forced to run al...
