Description
Technical field
The utility model relates to a kind of roller, specifically a kind of automatic clutch Mechanical Driven single vibratory road roller.
Background technology
Mechanical drive road roller in industry all adopts the manipulation form of artificial foot-operated power-transfer clutch at present; There is following problem in the roller of this artificial foot-operated clutch control: 1, manually tramples power-transfer clutch and cut off power transmission, increase the labour intensity of chaufeur; 2, manual control transmission of power and cut-out, easily causes physical shock, affects handling comfort and operation quality; 3, the required power element of the operating mode of artificial foot-operated power-transfer clutch is more, and trouble point is many, has reduced whole aircraft reliability.
Summary of the invention
The utility model provides a kind of automatic clutch Mechanical Driven single vibratory road roller, without artificial override type power-transfer clutch, effectively reduces chaufeur labour intensity; Simultaneously, without peripheral hardware clutch operating device, promote whole aircraft reliability, effectively avoid the physical shock that causes because driver's operation is improper, guarantee operation quality.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automatic clutch Mechanical Driven single vibratory road roller, forms power drive system by driving engine, manual transmission, transmission shaft, drive axle; Also comprise elastic coupling, bar handle and compensator pressure pump; Manual transmission is flexible shifting change speed gear box, and the clutch end of driving engine is connected with the power intake of flexible change speed gear box by elastic coupling, and the power intake of drive axle is connected with the clutch end of flexible change speed gear box by transmission shaft; Compensator pressure pump is connected with a power taking mouth of driving engine, and the import and export of compensator pressure pump inner fluid are all connected with flexible change speed gear box; Bar handle connects and controls flexible shifting change speed gear box.
In flexible change speed gear box, there is a set of above liquid clutch.
Bar handle is automatically controlled shift handle, is connected with flexible change speed gear box by cable.
Compared with existing type of drive: the utility model has been set up: elastic coupling and compensator pressure pump; Roller is without override type power-transfer clutch, and control comfort, effectively reduces chaufeur labour intensity, without peripheral hardware clutch operating device, promotes whole aircraft reliability, can effectively keep away the physical shock causing because driver's operation is improper, guarantees operation quality.
Accompanying drawing explanation
Fig. 1 is the utility model structure principle chart.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model automatic clutch Mechanical Driven single vibratory road roller, forms power drive system by driving engine, manual transmission, transmission shaft, drive axle, also comprises elastic coupling, bar handle and compensator pressure pump; Manual transmission is flexible shifting change speed gear box, and the clutch end of driving engine is connected with the power intake of flexible change speed gear box by elastic coupling, and the power intake of drive axle is connected with the clutch end of flexible change speed gear box by transmission shaft; Compensator pressure pump is connected with a power taking mouth of driving engine, and the import and export of compensator pressure pump inner fluid are all connected with flexible change speed gear box; Bar handle connects and controls flexible shifting change speed gear box.
Further, in flexible change speed gear box, there is a set of above liquid clutch, provide variable pressure fluid by compensator pressure pump, act on inner piston operation clutch-lining and realize the flexible combination of power-transfer clutch.
Further, bar handle is automatically controlled shift handle, can export the electric signal of gearshift and gear selecting, and it is connected with the solenoid directional control valve of flexible change speed gear box by cable, to realize the function of gearshift and gear selecting.
The utility model implementation process:
1, idling
Engine running, outputting power is to flexible change speed gear box and compensator pressure pump, now flexible change speed gear box and the zero load of compensator pressure pump.
2, advance or retreat
Engine running, outputting power is to flexible change speed gear box and compensator pressure pump.Then, manual operation bar handle, makes the electric signal of its output gear selecting and gearshift to the solenoid directional control valve of controlling flexible change speed gear box, and electric signal is output in 1～2 second after manual operation instruction provides.The solenoid directional control valve of flexible change speed gear box obtains, after electric signal, making corresponding actions, control high-pressure oil flow that compensator pressure pump outputs to flexible change speed gear box to.Then, high pressure oil acts on the piston of flexible change speed gear box inside, operates corresponding clutch-lining and realizes flexible combination, realizes the power output of flexible change speed gear box.Finally, the power of being exported by flexible change speed gear box is delivered to drive axle by transmission shaft, carries out advancing or retreating of roller.In whole process, the clutch action of transmission of power completes automatically, and artificial manipulation handle can be realized the entire exercise that advances or retreat.
3, braking
When roller is in the time advancing or retreat, step on foot brake, drive axle braking.Meanwhile, foot brake passes to speed-slackening signal the solenoid directional control valve of flexible change speed gear box, cuts off flexible change speed gear box power output, and this process participates in without clutch.
