Abstract

The invention relates to a general welding steering support. Wherein, it comprises frame, wheels, axial suspender, vibration reducer, and basic brake. The suspender has axial tank pad plate. The vibration reducer has inner round spring and outer round spring; the top of spring has spring cap; two sides of spring are arranged with suspension rings; the lifter is between the suspender and spring; the frame is mounted with empty-heavy vehicle adjuster which uses valve lifter to mount adjust valve, and under the adjust valve, the suspender is mounted with sensor valve base.

Description

(1) Technical field: [0001] A welded bogie relates to a railway freight transport device, in particular to a bogie for railway freight cars. (2) Technical background: [0002] The existing welded bogies have unsatisfactory performances of the damping device and the adjusting device for empty-loaded vehicles, and the frame structure is unscientific, which affects the applicability of the bogies. (3) Contents of the invention: [0003] The problem to be solved by the present invention is to provide a vibration damping device and an empty-load truck adjustment device with good performance, scientific frame structure and good applicability to weld the bogie in view of the above deficiencies. Its technical scheme is: it comprises frame, wheelset, axle box suspension device, damping device and foundation braking device, and axle box backing plate is arranged on the axle box suspension device. The damping device has an inner circle spring and an outer circle spring, a spring cap...
