MULTIPURPOSE VEHICLE Russian patent published in 2008 - IPC B60F1/00 B60F1/02 

FIELD: transport engineering.

SUBSTANCE: invention relates to vehicles which can move along roads and offroads and along railway tracks. Proposed multipurpose vehicle has body with power mounted on chassis and furnished with twin front steerable and rear driving wheels with tires with elastic disk placed between wheel disks. Tires of steerable and rear wheels arranged from outer side of each twin wheel have normal and side rigidity less than that of tires of inner wheels, and rigid disk is installed between disk of wheels. Said rigid disk has equal thickness over external generatrix and is made with profile adequate to profile of outer surface of rail head. Said disk plays part of wheel flange to permit operation of vehicle on rail track at reduced inner pressure of outer wheel tire relative to inner tire of inner wheel, or with possibility of movement along different roads and offroads with higher inner pressure of outer wheel tire relative to pressure of inner wheel tire.

EFFECT: simplified design, increased reliability.
