The specific embodiment:
As shown in Figure 1 and Figure 2, walking main pump 1, vibration main pump 5 place on the road roller chassis, preceding running motor 3 and preceding vibrating motor 7 are located on the front frame 11, active wheel 10 motions before can driving, and drive eccentric vibrating shaft 18 rotations, establish after running motor 4 behind the single-drum road roller on the vehicle frame 15, and establish after running motor 4 and after vibration motor 8 behind the dual-steel wheel road roller on the vehicle frame 15, can drive 14 motions of back active wheel and drive eccentric vibrating shaft 18 and rotate, each motion of mechanism is by HYDRAULIC CONTROL SYSTEM.The utility model single-drum road roller hydraulic system comprises walking main pump 1, preceding running motor 3, after running motor 4, vibration main pump 5, preceding vibrating motor 7, described walking main pump 1, preceding running motor 3, after running motor 4 is formed the complete machine vibration hydraulic systems, and vibration main pump 5, preceding vibrating motor 7 is formed vibratory hydraulic systems, it is characterized in that being provided with in vibration hydraulic system a walking transfer valve 2, this transfer valve is in parallel with walking main pump 1, and joins with preceding running motor 3 and after running motor 4 respectively, formation can be gone here and there, and the vibration hydraulic system that switches, by the residing state of motion decision vibration hydraulic system of walking transfer valve 2 spools; 5 of vibration main pumps and preceding vibrating motor 7 join in the described vibratory hydraulic system.As shown in Figure 3, the utility model double-steel wheeled vibratory hydraulic system is made up of vibration main pump 5, preceding vibrating motor 7 and after vibration motor 8, one vibration transfer valve 6 is set in this system, transfer valve 6 with join with preceding vibrating motor 7 and after vibration motor 8 respectively after vibration main pump 5 is in parallel, the motion by vibration transfer valve 6 spools decides the residing state of vibratory hydraulic system.
The utility model is a flow speed control valve 9 all in parallel on after running motor 4 and after vibration motor 8.The effect of flow speed control valve 9 is flows of regulating each motor in vibration hydraulic system, the vibratory hydraulic system, and active wheel 10 is consistent with back active wheel 14 speeds of travel before making, and guarantees that " bat is shaken " phenomenon does not appear in two vibrating wheels.
The utility model transmission process: motor 17 drives walking main pump 1, vibration main pump 5 rotates respectively, two pumps pump hydraulic oil respectively, the two-way hydraulic oil enters vibration hydraulic system connection in series-parallel transfer valve 2, vibratory hydraulic system connection in series-parallel transfer valve 6 by pipeline, these two valves are being controlled hydraulic system and are being in still state in parallel of series connection, (hydraulic state shown in Figure 3 is in state in parallel), when transfer valve 2,6 was in the another location, hydraulic system was in series connection.The two-way hydraulic oil is flowed through behind the hydraulic system transfer valve 2,6, running motor 3, after running motor 4 before flowing into respectively, and preceding vibrating motor 7, after vibration motor 8 make running motor, vibrating motor rotation.Running motor drives the active wheel rotation by walking driver plate 19, and generation is advanced, setback.Vibrating motor drives the rotation at a high speed of eccentric vibrating shaft 18 by shaft coupling 16, produces dither.
Vibration hydraulic system is in state in parallel during compacting operation, and vibrational system is selected series and parallel or state in parallel then according to the requirement of actual compacting material to vibration frequency.This mainly is according to soil vibration frequency to be required decision.This moment, drive system required to have bigger moment of torsion, lower speed, and parallel system can satisfy this characteristics just.When shifting the building site, need higher travel speed, the lower pressure of system requirements this moment, and higher operating rate, hydraulic system switches to train by transfer valve 2, can guarantee the pressure that system is certain, higher operating rate.When a certain driving shaft wheel of road roller is absorbed in mud ground, when occurring trackslipping, traditional hydraulic system in parallel is because its equalization of pressure characteristic, this moment, hydraulic system pressure foot in parallel depended on the wheel load that trackslips, this moment, adhesive power was similar to 0, system pressure is very low, driving torque is approximately 0, road roller can not climb out of from mud ground, and after this moment, hydraulic system switched to train, can guarantee hydraulic system pressure according to each situation coupling of taking turns load, the driving moment that the assurance system is enough is hauled out road roller from mud ground.
