Definitions

  • a belt drive for an internal combustion engine which has a crankshaft and a starter-generator.
  • the crankshaft is provided with a first pulley and the starter generator with a second pulley.
  • a belt spans the two pulleys.
  • the drive system according to the invention is characterized in that a power electronics unit is integrated space-saving in the drive system.
  • a power electronics unit is integrated space-saving in the drive system.
  • the integrated design also leads to an improvement in the electromagnetic compatibility, since only short electrical lines are needed. This is particularly favorable in modern vehicles, which usually include a large number of electrical components, such as control units.
  • drive systems which have a large bell housing and which designed for a high starting torque are an inventive design more space or volume for a power electronics unit available.
  • the electric machine 3 can also be operated as a motor and support the internal combustion engine 1, for example during acceleration of the motor vehicle (so-called boosting).
  • a power electronics unit 7 is provided, which according to the invention in the free space 6 between the internal combustion engine 1 and the transmission 2 is arranged.
  • This electronic power unit 7 comprises the usual, required for operating an electrical machine 3 components, such as converters consisting of semiconductor switches (eg transistors) or power semiconductors, freewheeling diodes, additional power semiconductors, possibly a power supply or power source, any circuit breakers and electric lines.
  • the power semiconductors used are preferably MOSFETs and / or IGBTs.
  • As the electric machine 3, a three-phase machine is usually used. Each phase or each rotor strand of the electric machine 3 is typically driven by power semiconductors, which are connected as a half-bridge.
  • the power electronics unit 7 is preferably designed such that it is at least partially annular and the drive shaft 4 and / or the transmission shaft 5 at least partially encloses.
  • An unillustrated housing of the power electronics unit 7 is preferably formed accordingly.
  • the flexibility in the design of a vehicle series can be increased, for example, by the use of different electrical machines. So is the volume or the size of the free space 6 is preferably selected such that when using an integrated electric machine instead of a belt-driven electric machine 3, this can be integrated into the free space 6 in addition to or instead of the power electronics unit 7.
  • This flexible utilization of the free space 6 allows for example to use different systems for realizing a start-stop operation within a vehicle series. In addition to packaging advantages, this also leads to cost advantages, since a restructuring of a drive train or drive system can be avoided, which would cause high costs.
  • a second, not shown, electric machine may be provided in the free space 6, which preferably serves to start the internal combustion engine 1.
  • This second electric machine is also referred to as additional starter.
  • the second electric machine is preferably connected in a form-fitting manner to the power electronics unit 7.
  • the power semiconductors or semiconductor elements required for driving this second electrical machine, in particular a converter, can be integrated in the power electronics unit.
  • the second electric machine is preferably at the radially farthest furthest from the drive shaft 4 and the transmission shaft 5, respectively, at the radially farthest point farthest side of the power electronics unit 7.
