Abstract

Official abstract text for this publication.

A transaxle includes a casing, an axle accommodated in the casing, an electric motor accommodated in the casing, a reduction gear train accommodated in the casing and transmitting an output of the electric motor to the axle, and a bull gear provided on the axle and coupled to the reduction gear train, in which the casing is configured such that a first casing and a second casing are separated and joined at a joint plane parallel to the axle, the bull gear and the axle are supported in the first casing, and the electric motor and the reduction gear train are supported in the second casing.

First claim

Opening claim text (preview).

What is claimed is: 1 . A transaxle comprising: a casing; an axle accommodated in the casing; an electric motor accommodated in the casing; a reduction gear train accommodated in the casing and transmitting an output of the electric motor to the axle; and a bull gear provided on the axle and coupled to the reduction gear train, wherein the casing is configured such that a first casing and a second casing are separated and joined at a joint plane parallel to the axle, the bull gear and the axle are supported in the first casing, and the electric motor and the reduction gear train are supported in the second casing. 2 . The transaxle according to claim 1 , wherein the axle includes a pair of left and right axles coupled in a differential manner by a differential gear mechanism provided on a rotational axis of the bull gear. 3 . The transaxle according to claim 1 , wherein the first casing is an upper housing which includes a mounting boss configured to attach the casing to a vehicle body and forms an upper side, and the second casing is a lower housing which forms a lower side. 4 . The transaxle according to claim 1 , wherein the electric motor is completely supported inside the second casing by a motor base portion formed in the second casing to hold the electric motor and a motor holding member detachably fixed to the motor base portion. 5 . The transaxle according to claim 1 , wherein a gear shaft of the reduction gear train is completely supported inside the second casing by a bearing base portion formed on the second casing to hold the gear shaft and a bearing holding member detachably fixed to the bearing base portion.
