Problems solved by technology

[0005] However, in the vehicular drive device of Patent Document 1, although the driving force source (2L, 2R) and the planetary gear mechanism (30A, 30B) are drivingly connected through the idler gear, it is sometimes impossible to obtain sufficient power in the idler gear. Reduction ratio
In order to increase the reduction ratio, it is considered to install a reverse gear mechanism instead of the idler gear, but in general, if the reverse gear mechanism is used, the vehicle drive device tends to become larger in the radial direction

Embodiment Construction

[0026] Hereinafter, the vehicle drive device 100 according to the embodiment will be described with reference to the drawings. Such as figure 1 as well as figure 2 As shown, the vehicle driving device 100 includes a first rotating electric machine 1A, a second rotating electric machine 1B, a first output member 2A drivingly connected to the first wheel W1, a second output member 2B drivingly connected to the second wheel W2, and a power source. Delivery device 3. In this embodiment, these are accommodated in case CS. In addition, a part of the first output member 2A and the second output member 2B is exposed outside the case CS.

[0027] Here, "drive connection" in this application refers to a state in which two rotating members are connected in a manner capable of transmitting a driving force, including a state in which the two rotating members are connected to rotate integrally, or the two rotating members A state in which members are connected so that driving force can...

Abstract

The present invention provides a vehicle drive device capable of ensuring a sufficient reduction ratio and capable of suppressing an increase in the size in the radial direction. Two drive power sources (1A, 1B) are disposed on a first shaft (X1), two output members (2A, 2B) are disposed on a second shaft (X2), and two counter gear mechanisms (5A, 5B) are disposed on a third shaft (X3). The planetary gear mechanism (6) is configured so as to transmit rotation from the two counter gear mechanisms (5A, 5B) to the respective output members (2A, 2B), and is disposed so as to overlap both of the two counter gear mechanisms (5A, 5B) in an axial view along the axial direction (L).

Description

technical field [0001] The present invention relates to a vehicle drive device including a first driving force source, a second driving force source, a first output member drivingly connected to a first wheel, and a second output member drivingly connected to a second wheel. Background technique [0002] An example of such a vehicle drive device is disclosed in Patent Document 1 below. Hereinafter, in the description of this background art, reference numerals of Patent Document 1 are quoted in parentheses. [0003] The vehicle driving device of Patent Document 1 includes a first driving force source (2L), a second driving force source (2R), a first output member (65c) drivingly connected to a first wheel (61L), and a second wheel ( 61R) drives the coupled second output member (65c), planetary gear mechanism (30A, 30B) and idler gear. The rotation shafts of the first driving force source (2L) and the second driving force source (2R) are arranged coaxially, and the rotation ...
