The second driving wheel 101 and the second driven wheel 102 are respectively mounted on both end surfaces of the lower vehicle body 100. Two baffles 301 are disposed on two sides of the cargo area 300, and the region between the two baffles 301 is the cargo area 300. A fork 302 is also provided in the cargo area 300 for picking and placing cargo. The two first driven wheels 202 are independently mounted on the lower vehicle body 100, and the two second driven wheels 102 are independently mounted on the upper vehicle body 200, without interfering with other structures.
The upper vehicle body 200 is also provided with a motor 203, a speed reducer 204 connected with the output end of the motor, a first gear box 205, a second gear box 206 and an intermediate transmission shaft 207 connected with the first gear box 205 and the second gear box 206. The first gearbox 205 and the second gearbox 206 are mounted outside the same baffle 301.
As shown in fig. 4 and 5, the first gear box 205 includes a first gear 208 coaxially connected to the output shaft of the speed reducer, a second gear 209 engaged with the first gear 208, and a third gear 210 engaged with the second gear 209. The third gear 210 is located below the second gear 209, and the third gear 210 is coaxially connected to one of the first driving wheels 201 to drive the first driving wheel 201 to rotate. The second gear box 206 includes a fourth gear 211, a fifth gear 212 positioned below the fourth gear 211 and engaged with the fourth gear 211, a sixth gear 213 positioned beside the fifth gear 212 and engaged with the fifth gear 212, a first bevel gear 214 coaxially connected with the sixth gear 213, a second bevel gear 215 engaged with the first bevel gear 214, and a bevel gear shaft 216 carrying the second bevel gear 215. The second gear 209 is coaxially connected to a fourth gear 211 via an intermediate transmission shaft 207. The fifth gear 212 is coaxially connected to the other first driving wheel 201.
The bevel gear shaft 216 is coaxially connected to a second driving wheel 101 by a first timing belt arrangement. The first timing belt device includes a first pulley 401 coaxially connected to one end of the bevel gear shaft 216, a second pulley 402 coaxially connected to one of the second driving wheels 101, and a timing belt 403 wound around the first pulley 401 and the second pulley 402. The other end of the bevel gear shaft 216 is coaxially connected to an extension shaft 217, which extension shaft 217 is coaxially connected to the other second driving wheel 101 by a second timing belt means. The second timing belt device includes a third pulley 404 coaxially connected to the extension shaft 217, a fourth pulley 405 coaxially connected to the other second driving wheel 101, and a timing belt 406 wound around the third pulley 404 and the fourth pulley 405. The connecting shaft between the second pulley 402 and the second driving wheel 101 passes through the upper vehicle body 200. The upper vehicle body 200 is provided with an opening (not numbered) through which the connecting shaft passes, and the opening does not interfere with the connecting shaft when the second driving wheel 101 moves up and down with respect to the upper vehicle body, so that the second pulley 402 can move up and down along with the second driving road 101. The connecting shaft between the fourth pulley 405 and the other second driving wheel 101 also passes through the upper body, which is likewise provided with an opening (not numbered) through which the connecting shaft passes.

The transmission principle in the above structure is that the motor 203 and the speed reducer 204 output power to drive the first gear 208 to rotate, the first gear 208 drives the second gear 209 and the third gear 210 to rotate (the third gear rotates to drive one first driving wheel 201 to rotate), the rotation output of the second gear 209 is transmitted to the fourth gear 211 through the intermediate transmission shaft 207, and the fourth gear 211 drives the fifth gear 212 and the sixth gear 213 to rotate. The fifth gear 212 rotates the other driving wheel 201. The sixth gear 213 drives the second bevel gear 215 and the bevel gear shaft 216 to rotate through the first bevel gear 214, so that the bevel gear shaft 216 drives one second driving wheel 101 to rotate through the first synchronous belt device, and the bevel gear shaft 216 simultaneously drives the other second driving wheel 101 to rotate through the extension shaft 217 and the second synchronous belt device. Thus, through the transmission path, the rotation output of the motor 203 can drive the two first driving gears 201 and the two second driving gears 101 to synchronously rotate.
In the embodiment, the motor can be used for driving the walking of the secondary road and the primary road of the four-way shuttle car only through one motor, so that compared with the double-motor walking driving of the existing four-way shuttle car on the market, one motor is saved, the cost is lower, and the control is simpler. And the motor drives the four-way shuttle vehicle to walk on the primary road and the secondary road, so that the power of the whole vehicle is lower, and the requirement on the capacity value of the battery is reduced. The requirement of the shuttle in the prior art is that the lower vehicle body can be lifted up and down relative to the upper vehicle body through the lifting mechanism so as to enable the wheels of the upper vehicle body or the wheels of the lower vehicle body to contact with the rails for reversing, so that the first synchronous belt device and the second synchronous belt device are connected with the second driving wheels in the embodiment, when the second driving wheels move up and down relative to the motor and the second gear box, the first synchronous belt device and the second synchronous belt device can keep the connection relation between the second driving wheels, the second gear box and the extension shaft through the flexible transmission characteristic of the synchronous belt, and the lifting movement of the second driving wheels can not lose the rotating power.
