BAFFLE FOR AUTOMOTIVE TRANSMISSION

摘要

A transmission in a vehicle includes a gearbox and a differential. Torque is transferred from an output of the gearbox to an input of the differential via a drive member. This transfers torque to enable the differential to distribute the torque amongst wheels of the vehicle. A transmission housing and a torque converter housing are mounted to one another to at least partially house the gearbox and the differential, respectively. A transmission fluid sump is provided between the housings where transmission fluid gathers. A fluid pump pressurizes the fluid and distributes it amongst working parts in the transmission. A baffle assembly partially contains the drive member and segregates the fluid sump from the drive member. One of the baffles in the assembly includes a lip engaging a portion of an outer flange of the pump to provide a seal between the fluid pump and components within the transmission.

1. A transmission comprising:
a torque converter housing; a fluid pump mounted to the torque converter housing and having an outer flange about a portion of a perimeter of the fluid pump; and a baffle having a base and a lip extending generally transverse from the base, the lip contacting a portion of the outer flange to provide a seal between the fluid pump and components within the transmission.
