DIRECTIONAL ROLLER BEARING RINGS AND BOGIES FOR THE PARIS METRO

COURONNES D'ORIENTATION ET BOGIES DE METRO

The author explains that a new link-up between body and bogie has been tested with success on coaches of the Paris Metro. The orientation of the bogies in relation to the body is effected by means of a crossed roller bearing ring. Small-radius curves can be taken very easily, and wheel flange wear is avoided. The directional roller bearing rings, which are pre-stressed during manufacture, provide a rigid assembly which gives the body excellent lateral stability. This rigidity also enables the bogie thrust centre to be lowered to axle level, which limits the transmission of bogie hunting movement to the body, and increases the comfort of the coaches.
