Definitions

  • This invention refers to internal combustion engines for motor vehicles provided with an electric starter and a current generator.
  • One of the primary requirements in the designing of motor vehicles, in particular for so called “city cars”, is to reduce the overall weight of the vehicle so that it can be driven using less power and therefore with less fuel consumption and less pollution.
  • the aim of this invention is to combine in a single electronic device the functions of the starter and of the current generator, simplifying at the same time the connection system to the combustion engine, as shown in document US-A-5 097 140. This and other aims are reached with an internal combustion engine according to claim 1.
  • Figure 1 is a partial cross section view of an internal combustion engine provided with an electric motor according to the invention.
  • Figure 2 is a cross section view of the electric motor manufactured in order to be mounted according to Figure 1.
  • the numeral 1 indicates an internal combustion engine (partially shown) provided with a crankshaft (3), and connecting rods (4) and pistons (5).
  • the crankshaft rotates in the engine block (7) on smooth bearings (8).
  • a gear (12) is splined, devoted to the operation of the engine distribution (camshaft).
  • a casing (14) is positioned around the end (10) of the crankshaft (3), fixed in a known way by means of bolts (not shown), which incorporates an inlet (15) for the feeding of lubricating oil into the engine.
  • Said casing (14) is made in the form of a circular shell, coaxially mounted to the crankshaft to form, with the windings (17) integrally mounted, the stator (18) of a brushless permanent magnet motor, in which the polarity can be inverted at any moment.
  • a second circular shell (22) is splined, coaxially to the casing (14), through the interposition of a seal (24), on the crankshaft (3) of the internal combustion engine (1), the shell of which rotates together with the crankshaft and carries on its periphery a series of permanent magnets (26) (facing, at work, the windings (17) ) and forms the rotor (27) of the electric motor.
  • Both components (14, 22) are cup shaped, positioned with their cavities facing each other and both components have an internal peripheral frontal rim, respectively (32) and (33), which cooperate to form, in counter rotation, a labyrinth seal for the protection of the motor (20).
