Abstract
A hybrid drive system includes a dual mass flywheel having an input side adapted for connection to a crankshaft of an internal combustion engine and an output. A dry damper assembly having an input flange is connected to an output of the dual mass flywheel and an output flange. An electric motor having a fixed mounted stator and a rotor is provided, and the output flange is connected to the rotor. A torque converter having a torque converter input is connected to the rotor and a torque converter output flange is adapted for connection to a downstream drive input shaft.
Claims14
A hybrid drive system, comprising:
- a dual mass flywheel having an input side adapted for connection to a crankshaft of an internal combustion engine and an output;
- a dry damper assembly having an input flange connected to an output of the dual mass flywheel and an output flange rotatably supported on the input flange;
- an electric motor having a fixed mounted stator and a rotor, and the output flange is connected to the rotor;
- a torque converter having a torque converter input connected to the rotor and a torque converter output flange adapted for connection to a downstream drive input shaft;
- and
- wherein the dual mass flywheel, the dry damper assembly, the rotor, and the torque converter are arranged about a common axis.
A dry damper assembly for use in a P1 hybrid drive system, the dry damper assembly comprising:
- an input flange adapted for connection to an output of a dual mass flywheel connected to an internal combustion engine;
- an output flange rotatably supported on the input flange;
- a plurality of springs located between the input flange and the output flange to damp a rotational movement between the input flange and the output flange;
- axially extending projections on an outer surface of the output flange that are adapted to be received in complementary recesses in a rotor or a rotor carrier of a hybrid motor;
- and
- axially extending projections on an outer surface of the input flange that are adapted to engage in recesses of the output of the dual mass flywheel.
