The power unit of drawbar category 1.4 tractors with integrated starter-generator

摘要

the tractor power unit comprises an internal combustion engine 1, the clutch 3, a transmission 2, the electric machine 4, a rotor position sensor 5. (FIG. 1). Electrical machine, placed between the internal combustion engine and clutch, enables starting of the engine and electric energy onboard the tractor network. A toothed rotor laminations 12 is placed on the flywheel 13 (Fig. 3). The power transmitted in both directions, up to 8 kW. Starter-generator replaces tractor drawbar class 1.4 (for example MTZ models LGZ) and the starter generator and internal combustion engine starting. The power source in the motor mode battery 9 are energy intensive and the capacitor 8 (Fig. 2). The proposed design of the starter-generator unit in the tractor provides optimum thermal conditions of the electrical machine by means of coolant circulating through the annular groove (Fig. 5) in the housing, the spacer 10 of the stator 11 (FIG. 3), and the damping crankshaft torsional vibrations ICE and electric drive tractor units.
