Operating principle As shown in FIG. 3, when the vehicle tries to change the direction, the rear drive wheel 2 is rotated in the opposite direction, and a constant driving force is obtained through the rotation of the pullback gear in the pullback type drive unit 103. When the device is released, the drive gear box output gear 202 starts to rotate, and the drive gear box output gear 202 and the clutch teeth 203 mesh with each other, so that the drive gear box output gear 202 is interlocked with the rotation.

When the driven wheel 204 starts to rotate, the driven wheel 204 and the transmission gear A205 mesh with each other, the transmission gear A205 and the transmission gear 206 mesh with each other, and the transmission gear 206 and the transmission gear B207
The first connection gear 208 and the transmission gear B209 mesh with each other, and the second connection gear 210 and the eccentric steering gear 211 mesh with each other. Therefore, the second connection gear 2
The eccentric steering gear 211 starts to rotate in conjunction with the rotation of 10, and the driven wheel 204
Since the tooth diameters of the first connecting gear 208 and the second connecting gear 210 are smaller than those of a plurality of sets of transmission gears, the degree of rotation of the gears can be reduced without impairing the movement of the device, and when steering. As shown in FIG. 7, when the eccentric steering gear 211 starts to rotate, the speed of the eccentric steering gear 211 is reduced to prevent the device from tipping over due to the steering speed being too high.
When the engaging lever 212 rotates in conjunction with the eccentric steering gear 211, when the engaging lever 212 rotates until it is perpendicular to one side of the steering connecting rod 213, the steering connecting rod 213 is steered by a certain angle. Since the steering connecting rod 213 is connected to the front steering wheel shaft 104, the front steering wheel 105 is also steered, whereby the front steering wheel 105 moves according to the S-shaped path and is steered as shown in FIG. When the connecting rod 213 swings and the return spring 106 is driven by the steering connecting rod 213 to change the torque and the pullback car body 1 is stationary, if the steering connecting rod 213 is not in a state perpendicular to the horizon, steering is performed. The connecting rod 213 swings so as to be in a vertical state by the action of the torque of the return spring 106, thereby rotating the front steering wheel 105 straight, and further, the total number of gears in the steering unit 2. By changing the number of gear teeth, it has the effect of running on other curves. For example, if you have a circular running type pullback car or an 8-shaped running type pullback car and you need to run the device in a straight line, the lifting lever When the 216 is moved to the second connection gear 210 side, the elevating lever 216 moves to the low end side of the elevating and tilting table 217 while the eccentric steering gear 211 is loaded, and the eccentric steering gear 21
When 1 moves until it is no longer coupled with the second connecting gear 210, the eccentric steering gear 211
Stops rotating and then continues to move the elevating lever 216 toward the second connecting gear 210 until the slide lever 218 and the curved slide base 219 are coupled, whereby the eccentric steering gear 211 is fixed and the device S Switching from character shape to straight running is realized.
