In the preferred embodiment typical structure schematic diagram that a kind of directional vibration of road roller provided by the invention shown in Figure 1 is taken turns; When the second power transmission shaft II and synchronous backward gear 5 manufacture same part, (be that structure merges here; Function merges); " nutating " when eccentric shaft 8 rotated in the middle of the Meshing Pair gap of adopting between the second power transmission shaft II and the middle eccentric shaft 8 (being the free deflection value that flexible connector allows) must increase to and be enough to isolate and the coaxiality error between synchronous backward gear 5 and the middle eccentric shaft 8 destroy the interference of synchronous backward gear 5; The second power transmission shaft II also can manufacture same part with middle eccentric shaft 8; At this moment; The Meshing Pair gap of adopting between the second power transmission shaft II and the synchronous backward gear 5 (being the free deflection value that flexible connector allows) also must increase to above-mentioned numerical value; Can the first power transmission shaft I and driven wheel 1 (or left avertence axle 7 or right avertence axle 9) be manufactured same part equally, this equivalents also is feasible, and universal driving shaft III can process same part with travelling gear 3 or synchronous transmission gear 4; As long as can guarantee synchronous any connected mode between rotation, travelling gear 3 and the synchronous transmission gear 4 in the same way of travelling gear 3 and synchronous transmission gear 4 all can select; Different choice, universal driving shaft III according to the connected mode between travelling gear 3 and the synchronous transmission gear 4 can omit sometimes; Travelling gear 3 can also be processed coaxial two-gang gear with synchronous transmission gear 4.
The course of work of the preferred embodiment of the directional vibration wheel of a kind of road roller provided by the invention is: vibrating motor 11 drives right avertence axle 9, driven wheel 1 and left avertence axle 7 simultaneously through the coupling 10 and the first power transmission shaft I, makes right avertence axle 9 and left avertence axle 7 do synchronously rotation in the same way; Driven wheel 1 Drive-Axle Gears 2, axle gear 2 drive travelling gears 3, travelling gear 3 through universal driving shaft III drive synchronous transmission gear 4, synchronous transmission gear 4 drive synchronous backward gear 5, synchronous backward gear 5 drive through the second power transmission shaft II in the middle of eccentric shaft 8; Eccentric shaft 8 is done and the rotation of left avertence axle 7 synchronous backwards in the middle of making; The centrifugal force that left avertence axle 7 produces when rotating at a high speed with middle eccentric shaft 8 is directly passed to steel wheel housing 21 through vibration bearing 12 and left vibrating shaft bearing 131, left vibrator housing 14, because the eccentric throw of middle eccentric shaft 8 equals the eccentric throw sum of left avertence axle 7 and right avertence axle 9; Owing between right avertence axle 9 and the middle eccentric shaft 8 gear-box 6 has been installed, therefore can accomplish to make L again
