Abstract

A case structure to accommodate a driving apparatus including a first motor and a second motor includes a first case, a second case, a first joint portion, an intermediate case, a positioning portion, and a first end portion of a second rotor or a second rotary shaft of the second motor. A stator of the first motor is to be attached to the first case. The second case is joined to the first case. The first joint portion is provided by joining a first end surface of the first case and an end surface of the second case together. The intermediate case is disposed on an inner diameter side of the first joint portion and attached to a stator of the second motor and to the first case. The intermediate case is positioned at the positioning portion with respect to the second case.

Description

technical field [0001] The present invention relates to a housing structure of a driving device, the driving device includes: a first motor including a rotor rotating together with a first rotating shaft and a stator arranged on the outer peripheral side of the rotor; a second motor including a second A rotor that rotates together with a rotating shaft and a stator disposed on the outer peripheral side of the rotor, the second rotating shaft is disposed on the same axis as the first rotating shaft; and a housing that accommodates the first motor and the second motor . Background technique [0002] Conventionally, there is a driving device for a hybrid vehicle including an engine and a motor. In such a drive device for a hybrid vehicle, as shown in Patent Document 1, for example, there is a structure in which, in addition to an engine as a drive source, an electric motor mainly for generating electricity, that is, a generator motor; An electric motor that functions as a dri...
