[0036] figure 1 It is a schematic diagram showing the overall structure of a vehicle equipped with the drive device 1 of the present invention. use figure 1 The structure related to the driving device 1 will be briefly described.

[0037] Such as figure 1 As shown, in the vehicle, for example, a drive device 1 , a control unit 2 and a battery unit 3 are arranged. In addition, although the example in which the control unit 2 and the battery unit 3 are not included in the drive device 1 is shown here, the control unit 2 and the battery unit 3 may be included in the drive device 1 .

[0038] The drive device 1 serves to drive a drive wheel 4 . The drive device 1 is mounted on a vehicle body (not shown). The drive device 1 operates with electric power from the battery unit 3 , and drives the drive wheels 4 via a first output shaft 5 (an example of an output shaft) and a second output shaft 6 . A first gear portion 7 is provided on the first output shaft 5 . A sec...

[0065] The structure of the second embodiment is basically the same as that of the first embodiment except for the structure of the rotation transmission structure 117 . Therefore, here, the description of the same configuration as that of the first embodiment will be omitted, and only the configuration different from that of the first embodiment will be described. In addition, the same code|symbol as 1st Embodiment is attached|subjected to the same structure as 1st Embodiment.

[0066] The rotation transmission structure 117 selectively transmits the rotation of the rotor 22 to the first output shaft 5 . The rotation transmission structure 17 is disposed in the inner space S of the casing 10 .

[0067] For example, the rotation transmission structure 117 has a planetary gear mechanism 118 . The rotation transmission structure 117 also has an electromagnetic clutch 119 .

[0068] In the internal space S of the casing 10 , the planetary gear mechanism 118 is arranged between...

Abstract

The invention provides a drive device for a vehicle, which can properly transmit the drive force of a motor to an output shaft. A vehicle drive device (1) transmits drive force to an output shaft (5).A vehicle drive device (1) is provided with a housing (10), an electric motor (13), a torque converter (15), and a rotation transmission structure (17). An electric motor (13) is provided with: a first stator (21) affixed to a housing (10); and a rotor (22) configured to be rotatable with respect to the first stator (21). When the rotor (22) rotates in a first rotational direction, the torque converter (15) transmits rotation of the rotor (22) to the output shaft (5). When the rotor (22) rotates in a second rotation direction opposite to the first rotation direction, the rotation transmissionstructure (17) transmits rotation of the rotor (22) to the output shaft (5).

Description

technical field [0001] The present invention relates to a vehicle drive device, and more particularly to a vehicle drive device for transmitting drive force to an output shaft. Background technique [0002] A conventional vehicle drive device includes an electric motor (electric motor) and a torque converter (see Patent Document 1). In this structure, the driving force of the electric motor is transmitted to the output shaft through the torque converter. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-231857 [0004] In a conventional drive device for a vehicle, when the vehicle moves forward, the electric motor rotates in the forward direction, and the driving force of the electric motor is transmitted to the output shaft through the torque converter. On the other hand, when the vehicle reverses, the electric motor is reversed, and the driving force of the electric motor is transmitted to the output shaft through the torque converter. [0005] In this conf...
