New description: [New technical field] This new type has a kind of driving device, especially a driving device for electric vehicles. [Prior Art] The driving devices of the conventional electric vehicles are mostly composed of a motor stator fixed to the motor main pump, a motor rotor housed on the motor main shaft, a speed reduction mechanism that is coupled with the motor rotor, and a clutch wheel and the like. And the clutch crying is generally installed on the motor main shaft or on the hub. Since the two clutches are installed at the low speed end of the speed reduction mechanism, the torque of the clutch is 4 to 5 times of the high speed end, thus It will accelerate the wear of the clutch, or the clutch snoring will occur when the load is heavy, and the existing dream of the car will be dangerous. Therefore, there is still room for improvement in the design of the electric early-end and the moving device. [New content] Therefore, the purpose of this new type is to improve the electric vehicle drive device that is easy to damage and stable. Therefore, the driving device of the electric vehicle of the present invention is suitable for driving a fish wheel, and the driving device comprises a motor vehicle, a dry wheel, a motor stator, and a motor rotor that can drive the rotating rotor. ... The mechanism that is attached to the 5 mechanism and the wheel hub by the horse mechanism, and a bouncer A, the motor rotor includes a gear seat and one or seven structures. The clutch is used to mount the motor rotor between the fixed seat and the gear base, and a hub and mesh with the gear base. The mechanism is fixed to the wheel. [Embodiment] 5 M349343, the above-mentioned and other technical contents, features and effects of the present invention are as follows. A detailed presentation of two preferred embodiments of the drawings is presented. "A" will be described in detail before the present invention is described in detail, and similar elements are denoted by the same reference numerals in the following description. Figure 7F of the washing machine of the present invention The following::: drives the wheel of an electric vehicle (not shown). The driving device: a hollow hub 2 coaxially fixed to the wheel, the left and right extension sleeves are pivotally connected to the hub 2 and are located at the wheel rotation. The main shaft 3 of the center, the motor stator 4 disposed in the wheel 2 and sleeved and fixed to the main shaft 3, can be pivotally pivoted relative to the main shaft 3 on the main shaft 3 and spaced around the radial outer side of the motor stator* The ring motor rotor 5, the clutch mechanism 6 provided in the hub 2 and mounted on the motor rotor 5, and the speed reduction mechanism 7 provided in the hub 2 and mounted between the wheel 2 and the clutch mechanism 6. 4 can be energized to drive the motor rotor 5 to rotate in a predetermined direction. The mechanism by which the motor rotor 5 rotates the motor rotor 5 is a conventional motor technology, and is not a modification of the present invention, so the clutch mechanism will not be described in detail. 6 includes a coaxial sleeve pivoted to the main The fixing seat 6 on the shaft 3 and fixed to the right side of the motor rotor 5 is sleeved on the radially outer side of the fixing base 61, and the outer peripheral surface radially protrudes from the gear seat 62 of the plurality of latching teeth 62〇, and is tightly fixed to the gear The inner peripheral surface of the seat 62 is unidirectionally pivotally biased against the clutch 63 of the outer peripheral surface of the fixed seat 61. The fixing base 61 has an annular fixed 6 M349343 portion 611 fixed to the right side of the motor rotor 5, and a self-fixing portion. The inner circumference of the 611 protrudes to the right and is pivotally disposed on the interlocking tube portion 612 outside the main shaft 3. The clutch stomach sleeve is a one-way bearing that is sleeved against the outer peripheral surface of the linking tube portion 612, and only the fixed seat motor rotor When the interlocking is pivoted, the card is locked against the outer peripheral surface of the interlocking (four) 612, and is synchronously pivoted by the fixed seat 61, and the gear holder 62 fixed to the outer peripheral surface thereof is synchronously pivoted. Since the type of the clutch 63 is numerous and the improvement target of the present invention is not improved, the n-thrust + the arrester is ten; the detailed structure of the δ 63 is not described in detail 'and the type of the clutch 63 is not implemented. This is limited to this. The speed reduction mechanism 7 includes a set of mounting shafts 71 fixed to the right side of the main shaft 3 and located on the right side of the clutch mechanism 6 , a fixed shaft 72 ′ that is eccentrically fixed to the mounting seat and extending to the left and right, and is pivotally mounted on the fixed shaft 72 . a transmission gear 73 that is coupled to the gear tooth 620 of the gear wheel, and a tooth tooth that is fixed to the inner circumferential surface of the hub 2 and has a number of days to engage with the transmission gear force:: internal tooth % 74 'and The internal ring gear 74 can be driven by the transmission gear 73 to drive the hub 2 to pivot 'and thereby drive the wheel to rotate. In the case of Bellow, the inner diameter of the inner ring 74 is larger than the outer diameter of the transmission gear 73: the outer diameter of the transmission gear 73 is larger than the outer diameter of the gear base 62, and the number of turns of the inner ring 74 is 93, and the value is not 4 4α transmission return wheel The number of teeth of the 73 is 33, and the number of teeth of the gear seat is 28, 'the design of the tooth through the inner ring 74 and the transmission gear is 'the design' can achieve the purpose of decelerating the wheel speed much less than the motor rotation + 5 speed. However, the design of the number of teeth of the actual 7, the gear base 62, the transmission gear 73 and the inner ring is not limited thereto. When the drive unit # Η 主 main 吏 ’ ’ ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” When the motor rotor 5 is driven, 'At this time, the center of rotation of the fixing base 61 is rotated synchronously against the connecting portion 612, and the (four) clutch 63 is locked by the locking card and transmitted through the gear holder 62. According to the 63 and the gear base 62, the synchronizing ring 74 rotates, and the interlocking wheel is forwarded by the two gears 73 and the inner electric vehicle. The wheel is rotated to drive the motor stator 4 to be unenergized. 5盥 The electromagnetic effect between the stator and the stator 4 will be discussed. The motor 疋 法 法 + + i + + + + 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子 子Electric car... When the drive is turned off without power, the hub 2 will drive the think-down mechanism 7_gear base 62, this day, the miscellaneous a# d hard rotor 5 is rotated in the forward direction The % clutch 63 is loose from the fixed seat 辏, mw μ: the person 疋 6i and is pivoted by the gear base 02. Therefore, the clutch 63 helmet 5 kinetic sill 61 rotates synchronously, and the motor is obtained at 5 and does not relative to each other. The motor 钤M 疋4 rotates to produce an electromagnetic effect that prevents the soap wheel from rotating. In the case of not starting the car # * f moving device, pushing the electric drive early, the wheel can still be rotated by the ball reduction mechanism 7 and the clutch gear 62 and the clutch 63 are rotated by the same, so that the electric 7 is still smoothly broken. Since the clutch is caught on the gear holder 62 and is located at the south speed end of the reduction mechanism 7, the 11-fold of the rotation of the clutch yoke 63 can be relatively reduced to slow the wear of the clutch 63. Further, the clutch is stretched to prevent the clutch 63 from slipping. (4): The second preferred embodiment of the driving device of the present electric vehicle is inferior to the first embodiment only in that: the clutch The structure of the mechanism 6 is set to 8 M349343. For convenience of explanation, the following faces are described in the following. In the present embodiment and the first embodiment, the fixed seat 61 of the clutch mechanism 6 is only used. The lock is fixed to the motor rotor and has a lock-like fixing portion 611. The clutch 63 is fastened and fixed to the outer peripheral surface of the gear holder 62, and the outer peripheral surface thereof is abutted against the solid portion 611. Closed, but only one-way frame relative to the fixed portion 611 Shishi, the above-mentioned clutch structure 6 design, the clutch 63 is also worn by the speed reduction mechanism 7; t;, φ _ Hume women show, so it can still relatively reduce the clutch I bearing I torque ' and The electric vehicle can be smoothly pushed forward before driving the electric vehicle. The electric vehicle can still be moved to the (four) 3 embodiment. The speed reduction mechanism 7 is only provided with the transmission gear 73, and only a plurality of transmissions can be eccentrically arranged on the 6-hai mount 71. The gears 73' and the transmission gears 73 are respectively sprayed between the inner ring gear 74 and the gear base 62 to more effectively drive the hub 2 to rotate. In the above, by placing the clutch mechanism 6 on the motor rotor 5, the structural design of the speed reducer cover 7 + ancient, A & , „. can greatly reduce the clutch '63 The torque of the party can be used to extend the service life of the clutch a and can improve the stability of the clutch 63. The slipping occurs. The clutch can be designed by the one-way clutch to make the drive not When it is moved, the electric car can still be smoothly pushed forward, which is quite convenient and practical. This can indeed achieve the purpose of this new type; at the same time, the above-mentioned clutch 63 months"* makes it easier to slide the vehicle, but Increase the cruising range; also prevent,, and a hope to damage the motor components; also avoid the vehicle reverse when the motor rotor $ is abnormally reversed. 9 M349343 However, the above is only the second preferred embodiment of the present invention. For example, the scope of the novel implementation cannot be limited by this, that is, the simple equivalent changes and modifications made by the novel patent application scope and the new description content are still within the scope of the novel patent. simply say 1 is a side cross-sectional view of the electric vehicle of the present invention; and FIG. 2 is a side cross-sectional view of the electric vehicle of the present invention.
