MILLING SNOW-REMOVING MACHINE Russian patent published in 1995 - IPC

FIELD: winter highways, streets, runways service. SUBSTANCE: milling snow-removing machine has base chassis 1 with separate drive of right and left side propelling devices 2, provided with driving semiaxes 5 and 6, and working organ in the form of mill, mounted on frame 11 with capability to rotate. Working organ is made of two coaxial to each other semi-mills 18 and 19 with separate drive in the form of increasing kinematic transmissions 20 between each of semi-axes 5 and 6 and corresponding semi-mill 18 and 19. Each increasing kinematic transmission 20 has chain with driven sprocket 21, fixed on outer end of semi-mill, and driving sprocket 22, rigidly linked with semi-axis of propelling device 2 of corresponding side of base chassis 1. Frame 11 of mill is mounted so as to be capable to turn in vertical plane in respect to semi-axes 5 and 6 of propelling devices of right and left sides. Transverse beam 12 of frame 11 is located between branches of chain transmissions 20 of semi-mills 18 and 19 drive. Differentiation of speeds of base chassis right and left sides propelling devices 2 in case of curvilinear movement of milling snow-removing machine is accompanied by corresponding automatic differentiation of semi-mills 18 and 19 rotation speeds. EFFECT: milling snow-removing machine is used in winter highways, streets, runways service. 3 cl, 3 dwg
