摘要

The bogie (1-9) frame has projecting side arms, connected to a transverse stretcher, and located between wheels sets resp. wheel pairs (6). The vehicle body has side support elements, which project downwards under the arms of the bogie frame. The body is suspended from the bogie frame via spring elements, which are cardanically joint between the arms of the bogie frame and the support elements. The spring elements consist of steel springs. They have parallel hydraulic damper elements. The vehicle body is also joint to the bogie frame via additional horizontal hydraulic damper elements. USE/ADVANTAGE - Bogie on railway vehicle has wear-proof secondary suspension, which also supports passive track curve-dependant body control.
