The shaft base 31 has a rocker 311 and a base body 312 attached to the lower edge of the rocker 311. The front end of the rocker 311 has a shaft end 31U disposed at the lower end of the rear arm seat 23, so that the whole The shaft base 31 is rotated by the shaft end 3111. The rocker rod 311 is provided with a pivoting ear portion 3112 at a position above the corresponding base body 312. The base body 312 is internally provided with a speed reducing mechanism. (not shown), the outer side of the wheel 32a of the drive wheel 32 is pivotally fixed, so that the position of the drive wheel 32 is located at the center of gravity of the center of the vehicle body 2'. In the present embodiment, the driver 33 is An electric motor is fixedly disposed at a rear side of the base body 312, and can just drive the speed reduction mechanism inside the base body 312 to operate, and then drive the drive wheel U through the speed reduction mechanism. The front wheel unit 40 has a front link 41 disposed at a rear of the vehicle body 2, a front wheel 42 disposed at a lower end of the front link 41, and a front link 41 and a hinge seat 31. First buffer element 43. The front link 41 enters the inside of the forearm plate base 22 and protrudes above the shaft seat 31, and a pivot point fixed to the inside of the forearm plate base 22 is provided at a middle portion thereof, so that the front link 41 is a fulcrum shaft 411. The front end of the front connecting rod 41 is provided with a cylindrical sleeve 4丨2 for fixing the front wheel 42, and a pivoting portion 413 is disposed at the rear end of the front connecting rod 41. The lower end of the cushioning member 4 3 is pivotally connected to the rocker. The cushioning member 43 is a spring shock absorber. The upper end is pivotally connected to the pivoting portion 413 of the front link 41, and the pivoting ear of the 311 is balanced. The workpiece 43 can cushion the impact bounce force of the front wheel 42 and provide the front wheel 42 with a lower buckling recombination force, and at the same time, the drive wheel 32 can be pressed down in conjunction with the shaft base 31. 1301756 The rear wheel unit 50 has a rear connecting rod 51 which is arranged in the front of the vehicle body 2〇 and can be swung in a four-bar type, and a rear connecting rod 51 which is disposed at the lower end of the rear connecting rod 51: rear:: 52, one connected to the rear connecting rod A second buffer element between the 51 and the vehicle body 2: 53, and a cup 54 pivotally coupled between the rear link 51 and the shaft base. The rear link 51 enters the inside of the rear arm plate base 23 and protrudes above the rotating shaft seat 31, and a pivot shaft 5U fixed to the rear arm plate seat ZZ is provided at the middle thereof, so that the rear connecting rod 51 is provided. With the fulcrum shaft 511 as the center of rotation, the lever oscillates, and the rear end of the rear link 51 is provided with a cylindrical sleeve 512 for the rear wheel to be inserted and fixed. 513, and the rear link .51 is provided at the front end - the shaft portion ^. In the embodiment, the second cushioning member 53 also uses a cage shock absorber, so that the rear end of the second cushioning member 53 is pivotally connected to the rear connecting rod. Η 接 = (1), the front end is pivotally fixed inside the rear arm seat 23, which can suppress the jumping motion of the rear wheel 5.2, and also restricts the upward travel of the driving wheel 32, and the second member 53 provides the rear wheel 52 with the lower The buckling force is applied to the pivoting portion 514 of the rear link 51, and the lower end is pivotally coupled to the first buffer element 43 on the pivoting ear portion 3112 of the rocker 311, such as The rotating shaft seat 31 can be driven down by the actuating rod 54. Dry 1 or more is an overview of the shape and combined space type of each component of the scooter having the transmission suspension system of the present invention; then, the action of the present invention is explained; and the expected effect can be achieved as follows: At the time of the second, when: the driving wheel 32 is walking on a protruding road surface (10), the 刖 link 41 of the early το 40 is subjected to the first cushioning element, and the point axis 411 is rotated in the clockwise direction. The pendulum is placed so that the front wheel 42 1301756 is pressed against the ground. The rear link 5i of the rear wheel unit 5G is rebounded by the first punching member 53, so that the rear wheel 52 is turned to the center. The counterclockwise rotation and the lower pressing are applied to the ground, whereby the front wheel 42, the driving wheel 3 2 and the rear wheel 4^ γ are in the same temple to maintain contact with the ground, so as to achieve a smooth walking effect of the two rounds. A drawing of the present invention, when the driving wheel 32 of the present invention is traveling on the low-lying road surface _ =, the front connecting rod 41 of the river wheel unit 4 is pressed by the front wheel 42 so that the front connecting cup 41 is counterclockwise with the pivot axis 4U as the center of rotation. The direction of the swinging, the front link 41 is controlled by the cushioning element 43 to provide a downward pressure to the driving wheel 32, so that the bowing wheel 32 can be brought into contact with the depressed road surface, and the rear link 51 of the rear wheel unit 50 is subjected to The rear vehicle is swung in the clockwise direction of the rear link 51 with the fulcrum axis as a center, and the rear link 51 provides a downward pressure to the drive wheel 32 by the actuating lever 54, thus ensuring the drive wheel μ and the ground. Keep contact with the residual space and make a three-wheeled flat walking effect. In summary, the present invention has the problem of the brake of the transmission suspension system. In order to solve the problem that the drive wheel unit 12 of the conventional electric scooter 1G is easy to turn around, the technical means of the present invention mainly utilizes the front wheel unit 40 and the rear. The wheel unit % and the intermediate driving wheel 32 are in an interactive linkage relationship. When the current and the rear vehicles 42 and 52 are walking on the uneven terrain, the driving wheel 32 is driven to perform an appropriate pressing action in the same time. 1. In addition to providing the function of buffering the shock absorber, the second buffering members 43 and 53 further provide elastic pressing force to the front and rear wheels 42, 52, so that the front and rear wheels can maintain contact with the ground. When the driving wheel 32 receives the material, the rear wheel unit is swayed, and the lower house is driven by the connecting rod, the driving wheel 32 can be kept in contact with the ground, 10 13〇1756. Thus, the invention can maintain the state of three-wheeled walking, the positive U » ^ '干月丨i ffi drive ^ ▼ The car body 20 travels, the travel process is quite smooth, safe and smooth. In addition, the drive wheel 32 is installed at the center of gravity of the car body 2〇, which helps the car body 20 to maintain One straight line Advancing, and the relative distance between the front and rear wheels 52 and the driving wheel 32 is shorter than that of a general vehicle, and the turning radius of the new car body 20 can be effectively smashed. Therefore, the handling of the present invention is quite sensitive, the turning ability is good, and the driving is extremely convenient. Travel effect. The above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the application of the present invention: the simple equivalent change of the scope of the invention and the description of the invention. And modifications are still within the scope of the invention patent.
