Embodiment Construction

[0021] Embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the same reference numerals in the drawings will denote the same or corresponding parts.

[0022] figure 1 is a sectional view of the automatic transmission 10 according to the embodiment of the present invention. Such as figure 1 As shown, an automatic transmission 10 is installed in a vehicle. The automatic transmission 10 is installed in an FF (Front Engine Front Drive) vehicle. In FF vehicles, the internal combustion engine is provided at the front of the vehicle and uses the front wheels as drive wheels.

[0023] The automatic transmission 10 includes a torque converter 11 , a shift mechanism 12 , and a differential mechanism 13 . The automatic transmission 10 is a transmission for a vehicle in which a shift mechanism 12 and a differential mechanism 13 are integrally provided.

[0024] The torque converter 11 transmits power from the engine...

Abstract

An automatic transmission (10) includes: a differential mechanism (13) which includes a ring gear (63); a case (75) which forms a differential chamber (21) that houses the differential mechanism (13); and an oil pan (73) which is fitted to the case (75), and which stores oil. The differential chamber includes a first space (26) in which the oil supplied from the oil pan is gathered, and a second space (27) which is formed on the opposite side of the first space with respect to the ring gear in the direction in which the rotational axis of the ring gear extends, and which is communicated with a space inside the oil pan. An oil passage (32), through which the oil is introduced from the first space to the second space, is formed in the case. The oil passage is formed in a bottom portion of the differential chamber.

Description

technical field [0001] The present invention generally relates to a transmission for a vehicle, and more particularly, the present invention relates to a transmission for a vehicle in which a shift mechanism and a differential mechanism are integrally provided. Background technique [0002] For example, Japanese Patent Application Publication No. 2004-36633 (JP-A-2004-36633) describes a housing for a conventional transmission for vehicles. By using such a housing in JP-A-2004-36633, the amount of lubricating oil in the housing is reduced, the lubricating oil is more properly supplied to the elements that need to be lubricated, and the resistance caused, for example, when the final drive gear stirs the oil is reduced . According to JP-A-2004-36633, a partition provided between the differential chamber and the oil pan chamber separates these chambers from each other. The differential chamber has a bottom and accommodates the differential unit. The oil pan chamber communicat...
