Problems solved by technology

In addition, especially when starting immediately after the vehicle is started at a low temperature, since the oil temperature is low, the viscous resistance of the oil is large, and there is a problem that the responsiveness of the hydraulic brake 128 cannot be improved.
[0007] In addition, in the driving device 100 described in Patent Document 1, since one electric motor 102 is distrib

[0132]

[0133] figure 2 10A and 10B are left and right axles on the rear wheel Wr side of the vehicle, and are coaxially arranged in the vehicle width direction. The reducer case 11 of the drive device 1A is formed in a substantially cylindrical shape as a whole, and inside it, motors 2A and 2B for driving axles and planetary gear reducers 12A and 12B that reduce the driving rotation of the motors 2A and 2B are arranged. On the same axis as the axles 10A, 10B. The electric motor 2A and the planetary gear reducer 12A control the left rear wheel LWr, the electric motor 2B and the planetary gear reducer 12B control the right rear wheel RWr, the electric motor 2A and the planetary gear reducer 12A, the electric motor 2B and the planetary gear The type speed reducer 12B is arranged in the speed reducer housing 11 to be bilaterally symmetrical in the vehicle width direction. and, as Image 6 As shown, the reduction gear case 11 is supported by the support parts 13a and 13b of...

[0145] Next refer to Figure 4 and Figure 5 A drive device according to a second embodiment of the present invention will be described. It should be noted that the drive device of the second embodiment has the same structure except that the arrangement of the drive device 1A, the hydraulic brake, and the one-way clutch of the first embodiment is different, so the same or equivalent parts are denoted by the same or equivalent symbols. , and its description is omitted.

[0146] Figure 4 In this figure, 10A and 10B are the left and right axles on the rear wheel Wr side of the vehicle, which are arranged coaxially in the vehicle width direction. The reducer case 11 of the drive device 1B is formed in a substantially cylindrical shape as a whole, and inside it, motors 2A and 2B for driving axles and planetary gear reducers 12A and 12B that reduce the driving rotation of the motors 2A and 2B are arranged. On the same axis as the axles 10A, 10B. The electric motor 2...

Abstract

A drive device (1A) provided with electric motors (2A, 2B) for outputting driving power and also with planetary gear type reduction gears (12A, 12B) arranged between axles (10A, 10B) connected to circular tube shafts (16A, 16B) serving as the output shafts of the electric motors (2A, 2B) and to rear wheels (LWr, RWr). The drive device (1A) is also provided with a unidirectional power transmitting means provided in a transmission route from the electric motors (2A, 2B) to the axles (10A, 10B) and transmitting the unidirectional rotational power of the electric motors (2A, 2B) to the axles (10A, 10B) and with a bidirectional power transmitting means for transmitting the bidirectional rotational power of the electric motors (2A, 2B) to the axles (10A, 10B).

Description

technical field [0001] The invention relates to a drive device and a vehicle with the drive device. Background technique [0002] As a driving device for a vehicle, a proposal has been proposed in which the left and right axles of the vehicle are connected to a differential device, and a motor arranged coaxially on the outer periphery of one axle shaft transmits a driving force to the differential device via a reduction mechanism (for example, Refer to Patent Document 1). [0003] like Figure 16 As shown, the driving device 100 has an axle driving motor 102, a planetary gear reducer 112 for decelerating the driving rotation of the motor 102, and an output of the planetary gear reducer 112 distributed to the left and right axles 110A of the vehicle. In differential device 113 of 110B, planetary gear reducer 112 and electric motor 102 are arranged coaxially on the outer peripheral side of one axle 110B coupled to differential device 113 . Moreover, the sun gear 121 and the ...
