The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
The present invention is made of the air pressure driver train.The air pressure driver train by compressed air source unit, advance/the reverse gear hand change over valve, the installation composition such as Pneumatic valve, Throttle Opening Control treadle valve, shuttle valve, Throttle Opening Control cylinder, engine throttle pull bar and pneumatic line.Source of the gas is provided by the air pump that is contained on the diesel engine, and is stored in the storage tank.Virgin state, switch valve 2 is in closed condition, and whole system there is not action, and the engine throttle pull bar is in raw bits.When vehicle need advance, at first toggle switch valve 2 is to the position of opening, be that switch valve commutates to left position, high pressure gas enter the pressure port of hand change over valve 4 by switch valve 2, and another road was clipped to the pressure port of Pneumatic valve 6 and Pneumatic valve 7 in 5 minutes through T-pipe joint 3 and T-pipe joint.When hand change over valve 4 is pulled D Drive (being that the left position of valve is connected), high pressure gas are through hand change over valve 4, one the tunnel enters the change speed gear box D Drive, another road enters the control mouth of Pneumatic valve 6, make this valve commutation, the blocking-up high pressure gas enter the Throttle Opening Control treadle valve 8 of operator's compartment, namely when advancing, only have the Throttle Opening Control treadle valve 9 of operator's compartment to work.At this moment, when stepping on the throttle control pedal valve 9, the plunger shaft that high pressure gas enter Throttle Opening Control cylinder 11 through Throttle Opening Control treadle valve 9, shuttle valve 10.The pushing piston motion, piston rod outwards ejects, and rocking arm 12 is take hinge as axial anticlockwise, and pulling push rod 13 is to left movement, thus the motion of pulling engine throttle pull bar, the control engine throttle increases gradually.When pin loosened the Throttle Opening Control treadle valve, high pressure gas were from the treadle valve off-load, Throttle Opening Control cylinder piston return under the effect of retracing spring, and rocking arm and push rod are got back to the initial position.In the process of slowly loosening, engine throttle is reduced to raw bits gradually.In like manner, when vehicle rollback, to advance/reverse gear hand change over valve 4 pulls backing car gear (be valve right position connect) down, high pressure gas are through hand change over valve 4, and one the tunnel enters the change speed gear box reverse, and another road enters the control mouth of Pneumatic valve 7, make this valve commutation, the blocking-up high pressure gas enter the Throttle Opening Control treadle valve 9 of operator's compartment, namely when reversing, only have the Throttle Opening Control treadle valve 8 in the operator's compartment to work.At this moment, when stepping on the throttle control pedal valve 8, the plunger shaft that high pressure gas enter Throttle Opening Control cylinder 11 through Throttle Opening Control treadle valve 8, shuttle valve 10.The pushing piston motion, piston rod outwards ejects, and rocking arm 12 is take hinge as axial anticlockwise, and pulling push rod 13 is to left movement, thus the motion of pulling engine throttle pull bar, the control engine throttle increases gradually.When pin loosened the Throttle Opening Control treadle valve, high pressure gas were from the treadle valve off-load, Throttle Opening Control cylinder piston return under the effect of retracing spring, and rocking arm and push rod are got back to raw bits.In the process of slowly loosening, engine throttle is reduced to raw bits gradually.
When so just having realized advancing, only have the Throttle Opening Control treadle valve 9 in the operator's compartment to work; During reversing, only have the Throttle Opening Control treadle valve 8 in the operator's compartment to work.Both satisfied the power control of bidirectional driving chamber, independence and the interlocking capability of Throttle Opening Control before and after having guaranteed again.
The hand change over valve that advances/move backward is three position five-way valve, and during meta, pressure port is obstructed, and two carry out mouth all is in unloading condition, and namely D Drive and reverse all do not have Output pressure, are in neutral.When commutation, D Drive or backward gear are connected.
The Throttle Opening Control treadle valve is proportional pressure-reducing valve, and the stroke that its delivery pressure and pedal are stepped on is proportional, and the angle of stepping on is larger, and the pressure of output is larger.
Switch valve is two-position three-way valve, and Pneumatic valve is two-bit triplet list Pneumatic valve.
The Throttle Opening Control cylinder is the proportional control cylinder, the proportional increase along with the increase of plunger shaft input pressure of piston rod delivery stroke.Thereby the ratio that has realized throttle increases and reduces.Piston rod and piston link together, and with the seal ring sealing, use seal ring seal between piston and the cylinder body.When high pressure gas enter plunger shaft by admission port, pushing piston and piston rod are to left movement, along with the rising of air pressure, overcome gradually retracing spring power, make different strokes, piston rod and rocking arm connect together, when piston rod during to left movement, promote rocking arm with hinge to anticlockwise, thereby the pulling pushrod movement, change the angle of accelerator rod, thereby change the size of engine throttle.
