A soil cultivating roller

Kushnir V.G.

Abstract

Structure and operation principle of an improved soil cultivating roller are given. Interaction between teeth and perforations on roller plates and cultivated soil prevents the displacement of soil particles to one of roller side faces. It ensures the uniformity of both cultivation depth and soil density, which are necessary for further high-quality sowing.

The problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices

Shipilevskiy G.B.

Abstract

Approaches to the problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices were examined. It is noted that well-timed shift should increase tractor velocity and a “successful” algorithm should not worsen its usability. Possible criteria were analyzed.

Performance and power inputs of machine and tractor aggregate

Antipin V.P., Vlasov Y.N., Karshev G.V., Kulikov V.N., Yepifanova A.Y.

Abstract

Results of analytical investigation of gear reduction rate and transmissive sequence choice for К-744Р-05 tractor transmission are presented. Regular transmission is estimated. Two methods of hyperbolic curve division into segments are examined, taking into account that product of tangential tractive effort and velocity is the constant and condition of an obligatory reserve of engine power for temporary overloads overcoming is fulfilled. Specified gear boxes types for different machine and tractor aggregates are recommended.
