For achieving the above object, the technical solution adopted in the utility model is: road roller bi-directional synchronization actuation means, it is characterized in that: comprise universal synchronous link, described universal synchronous link comprises first connecting rod, second connecting rod and for connecting the third connecting rod of first connecting rod and second connecting rod, described first connecting rod middle part is provided with coaxial mounted the second rotating shaft of the first rotating shaft with the hydraulic pump pumpage swing arm of walking, part near two ends on described second connecting rod is all connected with band meta bidirectional handle by handle bracing wire, part near two ends on described first connecting rod is all connected with engine throttle arm-tie frame by acceleration cable.
Above-mentioned road roller bi-directional synchronization actuation means, is characterized in that: on described first connecting rod, offer a plurality of for connecting the first installing hole of acceleration cable.
Above-mentioned road roller bi-directional synchronization actuation means, is characterized in that: on described second connecting rod, offer a plurality of the second installing holes for connecting handle bracing wire.
Above-mentioned road roller bi-directional synchronization actuation means, is characterized in that: described first connecting rod, second connecting rod and the third connecting rod structure that is formed in one.
The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design, be easy to install.
2, the utility model not pipe racks meta bidirectional handle leave meta forward or backward, can make throttle, discharge capacity is from little increase, from reducing greatly, and throttle and pumpage are synchronously increase or synchronously reduce.
3, the utility model can be adjusted the elasticity of acceleration cable by connecting the first different installing holes, can adjust the elasticity of handle bracing wire by connecting the second different installing holes.
4, of the present utility model to realize cost low, and result of use is good, is convenient to promote the use of.

The specific embodiment
Road roller bi-directional synchronization actuation means as depicted in figs. 1 and 2, comprise universal synchronous link 3, described universal synchronous link 3 comprises first connecting rod 3-1, second connecting rod 3-2 and for connecting the third connecting rod 3-3 of first connecting rod 3-1 and second connecting rod 3-2, described first connecting rod 3-1 middle part is provided with coaxial mounted the second rotating shaft 3-6 of the first rotating shaft 6-2 with the hydraulic pump 6 pumpage swing arm 6-1 that walk, the upper part near two ends of described second connecting rod 3-2 is all connected with band meta bidirectional handle 4 by handle bracing wire 5, the upper part near two ends of described first connecting rod 3-1 is all connected with engine throttle arm-tie frame 1 by acceleration cable 2.
As shown in Figure 1, on described first connecting rod 3-1, offer a plurality of for connecting the first installing hole 3-4 of acceleration cable 2.By connecting the first different installing hole 3-4, can adjust the elasticity of acceleration cable 2.On described second connecting rod 3-2, offer a plurality of the second installing hole 3-5 for connecting handle bracing wire 5.By connecting the second different installing hole 3-5, can adjust the elasticity of handle bracing wire 5.
In the present embodiment, described first connecting rod 3-1, second connecting rod 3-2 and the third connecting rod 3-3 structure that is formed in one.
During use, controlling band meta bidirectional handle 4 pushes away forward, handle bracing wire 5 can pull universal synchronous link 3, described universal synchronous link 3 drives pumpage swing arm 6-1 to rotate by the second rotating shaft 3-6, thereby make the discharge capacity of road wheel hydraulic pump 6 from little increase, simultaneously universal synchronous link 3 can rotate and then make acceleration cable 2 pull engine throttle arm-tie frame 1 according to the motive force of handle bracing wire 5, makes throttle simultaneously also from little increase, and then accomplishes that throttle and pump delivery synchronously increase.In like manner, control band meta bidirectional handle 4 to pusher, also can realize throttle and pump delivery synchronously increases.Pipe racks meta bidirectional handle 4 does not leave meta forward or backward, drives pumpage swing arm 6-1 rotation, can make throttle, and discharge capacity is from little increase, from reducing greatly.This road roller bi-directional synchronization actuation means can stop any position to discharge capacity under any rotating speed, well avoided large throttle, small displacement, also fixedly throttle and the nonsynchronous problem of pumpage have well been solved, make to control to reach and answer to one's liking hand, also make complete machine have good solution treating the destruction of in unexpected deceleration, ground being caused.
