Example 3
As shown in fig. 2, the present embodiment discloses a driving mechanism of a rack vehicle, which adds a new component on the basis of embodiment 1, wherein the new added component comprises a horizontal tooth 25 capable of meshing with a rack, and the horizontal tooth 25 is horizontally arranged and vertical to the vertical tooth 19. The cross gear 25 is in meshing transmission connection with the ninth gear 18 through a transmission component.
As shown in fig. 2 and 8, the transmission assembly connecting the cross-teeth 25 with the ninth gear 18 comprises: sixth gear 12, seventh gear 13, first bevel 20, second bevel 23 and fourth clutch 22.

When the driving part and the driven part of the fourth clutch 22 are disconnected, the transmission path between the second bevel teeth 23 and the cross teeth 25 is disconnected; when the driving and driven parts of the fourth clutch 22 are engaged, the transmission path between the second bevel teeth 23 and the cross teeth 25 is engaged.
As a preferable aspect of the present embodiment:
the transmission assembly further comprises a vertical shaft 24, and the driven part of the fourth clutch 22 is in transmission connection with the cross teeth 25 via the vertical shaft 24.

That is, the vertical teeth 19 can be meshed with the rack independently, and can also be meshed with the rack simultaneously with the horizontal teeth 25.
Furthermore, the top end of the vertical shaft 24 of the embodiment can be additionally provided with a brake 21.
