Abstract

The invention relates to a hybrid transmission coolant flow management system. A transmission assembly including a housing, an electric motor, and a baffle is provided. The housing may include first and second drainage channels. The electric motor may be disposed within the housing adjacent the drainage channels and a torque converter. The baffle may be disposed within the housing upon a housing inner surface, and may define an opening to the first and second drainage channels. The baffle may include a baffle flange sized for positioning adjacent the torque converter to minimize contact of oilwithin the housing to the torque converter. The housing may define first and second partition walls each partially extending over one of the first and second drainage channels. The baffle may furtherinclude first and second seal features each disposed at one of two baffle ends.

Description

Technical field [0001] The present disclosure relates to a coolant flow management system for a hybrid power transmission device of a vehicle. Background technique [0002] Vehicle torque converters usually operate in a dry environment. The torque converter of a hybrid power transmission device usually operates in a wet environment. Packaging constraints between the torque converter and the transmission may limit cooling oil emissions. For example, oil may accumulate around electric motors and torque converters. Such oil accumulation may cause rotational loss of the torque converter. Summary of the invention [0003] A transmission device assembly includes a housing, an electric motor and a baffle. The housing includes a first discharge channel and a second discharge channel. The electric motor is disposed in the housing adjacent to the first discharge passage, the second discharge passage, and the torque converter. The baffle is disposed on the inner surface of the housing ...
