AUTOMATIC TRANSMISSION CASING

摘要

An automatic transmission of a trans-axle type in which an input shaft is disposed above a differential across an axle of a vehicle. A case for the transmission is divided into a differential case for mounting a differential and a transmission case for an automatic transmission device. A bearing plate is disposed between the differential case and the transmission case. A drive pinion formed on an end of a drive pinion shaft is engaged with a ring gear of the differential. The drive pinion shaft is rotatably mounted in the bearing plate by a bearing, and an oil pump is provided in the bearing plate around the input shaft.
