Embodiment 1

[0048] Figure 1 Is a diagram illustrating the structure of the electric vehicle 10 of the present invention is appropriately applied. Electric vehicle 10 has an electric motor (rotating motor) 12 driving power as a driving force source to drive a pair of front wheels (multiple wheels) 14L, 14R front wheel drive device (vehicle drive) 16. as Figure 1 As shown, the front wheel drive device 16 is provided with an electric motor 12, the driving force from the electric motor 12 is transmitted to the left and right pairs of front wheels 14L, 14R power transmission mechanism 18, containing electric motor 12 and power transmission mechanism 18 and the containment housing 20 and the left and right pair of front wheels 14L, 14R together with the drive shaft 22L, 22R. Further, in the power transmission mechanism 18 is provided with a differential device 24 and a reduction gear mechanism 26, the differential device 24 through the drive shaft 22L, 22R can transmit power to the left and right ...

Abstract

The present invention provides a vehicle drive device capable of appropriately reducing the number of components in a vehicle drive device that selectively locks or unlocks wheels. The switching mechanism is capable of selectively connecting the drive gear to one of the receiving housing as a non-rotating member and the input shaft using an actuator and a disconnect sleeve that is controlled by the actuator in the first axis of rotation. Drive in the direction to selectively disconnect or connect the drive gear and the input shaft. Thus, when the vehicle is not driven, that is, when the drive gear and the input shaft are disconnected, the drive gear is connected to the housing case as a non-rotating member to lock the left and right pair of front wheels. The device and the disconnect sleeve can be appropriately reduced in the number of parts constituting the drive unit for the front wheels.

Description

Technical field [0001] The present invention relates to a technique for appropriately reducing the number of components constituting the vehicle drive device in the wheel selectively locked or unlocked. Background [0002] It is known that there are the following vehicle drives, having: (a) rotating motors, the rotating motor becomes a driving force source for a plurality of wheels; (b) the input shaft, the input shaft and the rotating motor capable of transmitting power is connected, and is provided to be able to rotate around the first axis of rotation; (c) and the countershaft, the countershaft is provided to be able to rotate around the second axis of rotation parallel to the first axis of rotation, (d) via the input shaft and the countershaft from the driving force from the rotating motor is transmitted to the plurality of wheels to drive the plurality of wheels. For example, the vehicle drive device described in patent document 1 is such a vehicle drive device. Further, in ...
