FIELD: transport engineering. SUBSTANCE: proposed system contains support frame 11 formed by two legs 17, 18 hinge intercoupled for turning around two end axles 21, 22. Two inclined guide rollers 14 moving along guide rail 8 are installed on each leg. Support frame 11 is installed for displacement in longitudinal direction relative to wheel axle of vehicle, thus providing reversing of automatically controlled movement under action of power reversing drive 15. Support frame 11 can be lifted by lifting mechanism acting onto levers of support frame after releasing of guide rollers 14 from contact with guide rail 8. Wheel axle is automatically controlled in direction of movement by means of subsystem 9 operated by support frame 11. Controlled subsystem 9 provides possibility of deflection in cross direction from behind around point of turning located in close vicinity to front guide rollers. Proposed possibility of reversing is expedient for vehicles whose movement is controlled by guide rail. EFFECT: prevention of derailment of guide rollers from guide rail in motion. 20 cl, 12 dwg |
