Description of the Invention: [Technical Field of the Invention] The present invention relates to a handling facility (4), and more specifically to a self-propelled handling vehicle. [Prior Art] Please refer to the first figure. The truck 100 used to carry goods in the workplace is used to move the truck 100 by manual pushing and pulling. However, the method of manual pushing and pulling is not only laborious, but also long-term. It will also cause the user's muscle soreness to cause more occupational injuries. In order to improve the above disadvantages, please refer to the second figure. A manufacturer has invented a self-propelled truck 200, which is provided with a power source 212 on the vehicle body 210 to drive the wheels 214 under the vehicle body 2 (7), and utilizes the control device. 216 controls the power output of the power source 212, thereby allowing the wire to be driven by the secret force, thereby driving the body 210 to move, thereby making the handling work more labor-saving and safe. However, since the self-propelled transport vehicle 200 uses the power source 212 to simultaneously drive the two wheels 214 at the rear end of the vehicle body 210, the radius of gyration of the self-propelled transport vehicle during the fine turn is excessive. In other words, when the space around which the self-propelled transport vehicle can move is small, or when the travel path encounters an obstacle, the self-propelled transport vehicle 200 cannot be steered. Moreover, when the power source 212 is changed to drive the two wheels 218 at the front end of the vehicle body, the above disadvantages are also generated. In addition, the wheel 214 of the self-propelled truck 200 that is driven to rotate is fixed at the same level. That is, when the self-propelled truck 200 passes through the pitted road surface in 201208964, the wheel 2U at the pit is idling, which causes the traveling path of the self-propelled truck to shift. Or through the road with the bumps (4), the body 21 will cause a large tilt and the risk of overturning. Therefore, the above-mentioned self-propelled transport vehicle 2 is still not perfect and needs to be improved. SUMMARY OF THE INVENTION In view of the above, it is a primary object of the present invention to provide a self-propelled transport vehicle that can be tilted and thinned in a vehicle body in the same direction as the vehicle. In order to achieve the above object, the self-propelled truck provided by the present invention comprises a vehicle body to a V-assisted wheel, two power wheels, two connecting machines, and a control device. The towel, the bribe paste _ minute ^ segment, the middle segment and the - rear segment ' and has a load-bearing portion for hiding articles; the at least the support wheels are respectively disposed in the front and rear portions of the vehicle body; the two power wheels are The wheel surface gamma is on the surface; the second _ knot mechanism is the second power wheel and the scale body, and the Wei two power touches the middle section of the scale, and the wonderful ^ power shots are close to or _ scales In the movement, the two motors are disposed on the vehicle body for respectively driving the control devices, and the ribs are respectively rotated and lying. [Embodiment] 201208964 In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the accompanying drawings. The self-propelled van 1' of the first preferred embodiment of the present invention includes a vehicle body 10, four auxiliary wheels 2, two connecting mechanisms 30, and two The power wheel 40, two shock absorbers, two motors 6A, and a control device 70. Among them: The body ίο is divided into a front section 1〇a, a middle section i〇b and a • rear & 1〇 according to the direction of travel. And having a carrying portion 12, a lifting device Μ and two pedals I6. The carrying portion 12 is a platform, and the ribs are placed for articles to be transported. The lifting device 14 is disposed under the carrying portion 12 for changing the height of the carrying portion 12 to make it more convenient when the article is taken or placed. The two pedals 16 are available for the user to step on and stand for the user to move with the body 10. In addition, the vehicle body 1G can be folded when not in use, and the design can facilitate the storage of the vehicle body 10, so that the space can be more flexible. • The four auxiliary wheels 20 are disposed under the vehicle body 10 to maintain the balance of the vehicle body 10. The four auxiliary wheels 2〇 are divided into two front auxiliary wheels 2〇a and two rear auxiliary wheels 20b, wherein the two front auxiliary wheels 2〇a are disposed on the front side of the vehicle body 1a and the rear auxiliary wheel 2% is set in the rear of the car. Of course, in the design, only the 1G can be used to maintain the balance. It can also be used as the sixth and seventh figures. Referring to the eighth figure, the two connecting mechanisms 30 respectively have a bracket 31, and the two brackets 31 are pivoted on the two sides of the scale 1G surface. This item] 5 201208964 The force wheel 4 is pivoted on the two brackets by the pivot shaft 32, and is located at the middle section 10b of the vehicle body 10, which is located on the two sides of the body 1 In this way, the two power wheels 4 can use the connection mechanisms 3 to perform the Wei or Yuan 1G money according to a predetermined path. The purpose of this design is that the Tianzi truck 1 has a slanting ground (9) as shown in the ninth figure, or has a slanting ground such as the tenth riding 151. The wheel 4 is immediately approached or away from the vehicle body according to the road condition, so that the wheel surface can be attached to the ground at any time, so as to avoid the self-propelled transporter driving on the uneven ground. The tread 4〇a cannot be touched to the ground and idling, resulting in a misaligned lion. In addition, it is possible to avoid the danger that the body 10 is inclined and pure due to unevenness of the ground. The second shock absorber 5G includes an upper sleeve 5, a post 52, a lower sleeve 53, a spring 54, and a damping oil 55, respectively. The upper sleeve is pivotally connected to the material (4), and (10) is provided with a % of the oil; the pillar 52 is end-scaled in the upper sleeve S1, and the other end is fixed to the lower sleeve 53; The lower sleeve 53 is connected to the bearing shaft 33 of the connecting mechanism 3; the spring 54 is disposed on the support rod 52, and the two ends thereof are in contact with the upper sleeve 51 and the 7 sleeve 53. Thereby, the spring force generated by the magazine 54 and the force generated by the damping 5 are used to reduce the vibration generated when the power wheel 4 () is approaching or moving away from the reciprocating motion of the body. In addition, the two shock absorbers 50 can further utilize the spring 53 to increase the speed of the second power wheel to move closer to or away from the vehicle, so that the corresponding road surface can be adjusted in time for the purpose of 201208964. Of course, in terms of design, in addition to using the above-mentioned other fields, the village will be fine-grained; The fine structure is a conventional belt. The belt is _ _ _ the power wheels 40 ‘of course, the design can also be · chain storage wheel ··· etc. Transmission belts for the purpose of the power transmission wheel. The control device 70 is disposed on the vehicle body
