FIELD: transport.
SUBSTANCE: invention relates to machine building. Wheeled version of caterpillar tractor comprises drive wheels and portal axle. Drive wheels are driven by engine via two double-flow transmission and double-flow drive axle by hydraulic clamping couplings. Portal axle with turning wheels interconnected by transverse tie rods are provided with turning wheel axle pins in inclined journals. Said journals are fitted in portal axle tubular beam to be extended as required. Every journal moves about tubular beam axle to vary its inclination and lock said position. Axle pin is articulated with centering hydraulic cylinder so that said cylinder has minimum length while its axial line runs along turning wheel axle. Cavities of centering hydraulic cylinder are communicated via hydraulic lock with cavities of hydraulic cylinder built in trapezoid cross beam and with tractor hydraulic control valve. Rod end of centering hydraulic cylinder communicates with hydraulic throw-in/out control valve and brake throw-in hydraulic cylinder.
EFFECT: decreased radius of turn.
