Transmission e.g. automatic transmission, for e.g. passenger car, has air circulation device provided with air inlet opening of housing portion for admitting air in receiving space and air outlet opening for discharging air from space

摘要

The transmission (10) has a coupling device e.g. hydrodynamic coupling, for introducing rotational torque and rotation speed of an aggregate (36) into the transmission. The coupling device is arranged in a receiving space partly limited by a housing portion (14) of the transmission. An air circulation device (26) is provided with an air inlet opening (28) i.e. hood, of the housing portion for admitting air in the receiving space and an air outlet opening (30) i.e. diffuser, of the housing portion for discharging the air from the space. The inlet opening is arranged in a region (32).
