construction and road-building machinery; pneumatic wheel excavators. SUBSTANCE: pneumatic wheel running gear has running gear frame with support and slewing gear coupled with frame of two axles, one of which is secured on frame by means of hinge joint for turning in horizontal plane under action of control cylinder. Other axle secured on frame for turning in horizontal plane is connected with first axle by tie-rod to form articulated four-member mechanism. EFFECT: simplified steering and wheel rotation drive system, reduced radius of turning at reliable control of turning even on rough terrains. 5 dwg
