Tramway and urban railway bogie - in which articulated body ends are carried on plate held on bogie frame by springs avoiding kinematic problems

摘要

The bogie is for tramways and urban railways with articulated bodies. The bogie supports the end of two body sections. The bogie has two axles (3) between its frame (2) and the two bodies is a plate (7) carrying two pivots (8), supporting the body ends. The plate is carried on four springs (5) which are associated with a shock absorber each. There are sliding support shoes (10) on top of the plate (7). The bodies are thus not supported on a single point but the bogie is also immune from kinematic problems due to absence of turning effort on the springs.
