Abstract

A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.
