A hybrid drive system, electrical drive module and the cooling arrangement

摘要

The present invention relates to a a hybrid drive system, an electrical drive module and the cooling arrangement. The electrical drive module comprises a hollow housing, an electric motor, a cooling arrangement and a coupling, whereby the electric motor and the clutch in the hollow housing are mounted, the cooling arrangement a bottom wall and a extending from the bottom wall and with it an integrated cooling liquid sleeve, the cooling arrangement for example, by means of fastening bolts at one end of the body and is fastened by means of a sealing ring in the cooling arrangement is mounted, in addition, the bottom wall has an opening, and the actuator of the clutch is mounted on the opening. The electrical drive module according to the invention simplifies the production of the housing of the electrical drive module, increases the rigidity of the electrical drive module, reduces the axial length of the electrical drive module and increases the degree of utilisation of the production materials.
