A guide wheel assembly (14), which can be preassembled as a single unit, is configured to be connectable to a guide frame (12) of a rail guided vehicle (10). The guide wheel assembly (14) generally includes a fixed component (18) connectable to the guide frame (12) and a rotating component (20) rotatably supported on the fixed component (18) by a bearing assembly (22). The elements of the fixed component (18), the rotating component (20) and the bearing assembly (22) are assembled on a shaft (24) of the fixed component (18) from a top or first end thereof. The shaft (24) includes a support member (40) secured at a second end of the shaft (24) and configured to prevent the rotating component (20) from detaching from the fixed component (18) in the event of bearing failure. Selon l'invention, on a agencé cet ensemble roues de guidage (14), que l'on peut préalablement assembler sous forme monobloc, de façon à pouvoir le raccorder à un châssis de guidage (12) d'un véhicule sur rail (10). Cet ensemble roues de guidage (14) comprend généralement un élément fixe (18) que l'on peut raccorder au châssis (12) ainsi qu'un élément rotatif (20) monté rotatif sur l'élément fixe (18) au moyen d'un ensemble palier (22). Les pièces de l'élément fixe (18), de l'élément rotatif (20) et de l'ensemble palier (22) sont assemblées sur un arbre (24) de l'élément fixe (18) à partir du sommet ou d'une première extrémité de celui-ci. Cet arbre (24) comprend un élément de support (40) fixé au niveau d'une seconde extrémité de l'arbre (24) et conçu pour empêcher l'élément rotatif (20) de se détacher de l'élément fixe (18) en cas de défaillance du palier.
