Abstract
Official abstract text for this publication.
A vehicle automatic transmission of a multistage type having a plurality of shift stages selectively established depending on a combination of engagement and release of multiple engagement elements, comprises: a torque converter coupled to an input rotating member of the automatic transmission; an oil pump coupled to a pump side of the torque converter, at least one of the multiple engagement elements being a meshing engagement element, and the meshing engagement element being at least partially disposed on an inner circumferential side of at least one of the torque converter and the oil pump.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle automatic transmission of a multistage type having a plurality of shift stages selectively established depending on a combination of engagement and release of multiple engagement elements, comprising: a torque converter coupled to an input rotating member of the automatic transmission; and an oil pump coupled to a pump side of the torque converter, at least one of the multiple engagement elements being a meshing engagement element, and the meshing engagement element being at least partially disposed on an inner circumferential side of at least one of the torque converter and the oil pump, wherein the meshing engagement element includes a portion which is located inwardly of the at least one of the torque converter and the oil pump in a radial direction perpendicular to an axis of the vehicle automatic transmission, and which overlaps with the at least one of the torque converter and the oil pump in an axial direction parallel to the axis of the vehicle automatic transmission. 2. A vehicle automatic transmission of a multistage type having a plurality of shift stages selectively established depending on a combination of engagement and release of multiple engagement elements, comprising: a torque converter coupled to an input rotating member of the automatic transmission; and an oil pump coupled to a pump side of the torque converter, at least one of the multiple engagement elements being a meshing engagement element, and the meshing engagement element being at least partially disposed on an inner circumferential side of at least one of the torque converter and the oil pump, the vehicle automatic transmission further comprising an output rotating member; and a planetary gear device configured to transmit power inputted to the input rotating member, to the output rotating member, wherein the meshing engagement element is disposed between the input rotating member and a rotating element of the planetary gear device, and is configured to selectively engage the input rotating member and the rotating element.
