Bogie support for pref. railway vehicles

摘要

The vehicle has a body (91) and two bogies (92, 93) and a hydraulic working cylinder (51, 52) between them, with a stepped piston (31, 32), which is loaded on three faces. The spaces (1) above the piston rods are connected to each other and to the storage pocket (21) via a pipe line (11), forming a compound circuit. The space (2) above each piston is connected to that (3) below each piston and to the storage pocket (22, 23), via pipe lines (12, 13), forming a differential circuit. Each pipe line is connected to a storage pocket, and vehicle body resp. bogies carry e.g. mechanical rolling supports.
