Embodiment Construction

[0025] Embodiments of a vehicle drive device will be described with reference to the drawings.

[0026] In the following description, "rotating electrical machine" is used as a concept that also includes a motor (electric motor), a generator (generator) and, if necessary, a motor generator that realizes both the functions of the motor and the generator.

[0027] In addition, "drive coupling" refers to the state in which two rotating members are coupled so that a driving force can be transmitted. This concept includes a state in which two rotating members are connected to rotate integrally, and a state in which two rotating members are connected so that driving force can be transmitted via one or more transmission members. Such transmission components include various components (shafts, gear mechanisms, belts, chains, etc.) that transmit rotation at the same speed or at variable speeds, and may also include devices that selectively transmit rotation and driving force (friction ...

Abstract

A vehicular driving apparatus (1) of the present invention comprises a rotary electric machine, an output member (O), and a planetary gear unit (PG2) for speed reduction. The output member (O) and the planetary gear unit (PG2) for speed reduction are arranged coaxially and side by side. The planetary gear unit (PG2) for speed reduction has a third rotary element (R2) that is selectively fixed to a case (2) through an engagement device (65). A support bearing (82) that supports the third rotary element (R2) in a rotatable state is supported by the output member (O) in a radial direction.

Description

technical field [0001] The invention relates to a driving device for a vehicle. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 6-339248 (Patent Document 1) discloses a drive device for a vehicle including a rotating electric machine, a planetary gear device for reduction, and a case for accommodating them. In the device of Patent Document 1, the ring gear of the deceleration planetary gear unit is always fixed to the case, but it is considered that an engaging device is interposed between the ring gear and the case so that the fixing of the ring gear can be released. . [0003] Japanese Patent Application Laid-Open No. 2017-197128 (Patent Document 2) discloses a structure in which the ring gear can be selectively fixed to the case by such an engaging device. In the device of Patent Document 2, when the fixation of the ring gear [second ring gear 22] is released, the ring gear and the member supporting it [ring gear flange 221] are rota...
