STARTER-GENERATOR SET OF VEHICLE

摘要

FIELD: automotive industry.SUBSTANCE: proposed starter-generator set of vehicle comprises a reversible electrical machine comprising a stator (1) connected to the housing (2) of the internal combustion engine, a rotor (3) connected by the threaded fasteners to the shaft (4) of the engine, a casing (5) attached to the housing (2) of the engine. The stator is connected by the electric circuit to the accumulator battery. The rotor is made in the form of a toroidal bowl having at the periphery the windows (6) separated by partitions formed by long curvilinear blades (7), (8) located on the concave surface of the bowl facing the stator (1). Part of the partitions between the windows in the bowl is formed by long blades (7), and the other equal part of the partitions - by short blades (8) located between the long blades (7). The bowl is attached to the hoop (9) surrounding the stator (1). In the hoop (9) in front of the stator an elastic cylindrical ring (10) of resin-bonded magnet is inserted. In the casing (5) along the axis of the electrical machine there are two rows of ventilation openings (11) and (12) separated by a tapered ridge (13) made on the inner surface of the casing opposite the rotor and protruding towards the said hoop (9).EFFECT: ensuring effective cooling of the starter-generator set for compliance with optimum thermal mode of its operation.2 cl, 2 dwg
