Abstract
The invention relates to a shifting device for a tandem vibratory roller. The device is characterized by comprising a shift control handle (1), a handle controller (2), a shift changeover switch (3) and a running variable pump proportional electromagnetic valve coil (4), wherein the input end of the shift changeover switch (3) is connected with the output end of the handle controller (2); the output end of the shift changeover switch (3) is connected with one end of the running variable pump proportional electromagnetic valve coil (4); the input end of the handle controller (2) is connected with the OUT+ end of the shift control handle (1); and the OUT- end of the shift control handle (1) is connected with the public end of the handle controller (2) and the other end of the running variable pump proportional electromagnetic valve coil (4). The invention ensures that a running hydraulic system of the tandem vibratory roller can realize changeover of shift under combination of a variable plunger pump and a quantitative plunger motor, and the cost of the quantitative plunger motor is only about half of that of the variable plunger pump. The design can effectively control manufacture cost, and realize shift requirement of a user on the tandem vibratory roller.
Description
(1) technical field
The present invention relates to a kind of vibratory roller, especially relate to a kind of shifting device for tandem vibratory roller.Belong to technical field of engineering machinery.
(2) background technology
The transforming gear of at present traditional double-steel wheeled vibratory roller is to realize through the displacement variation that changes running motor; The composition of vibration hydraulic system must be made up of Variable plunger pump+variable piston motor like this; Though such combination can be according to the different operating modes of double-steel wheeled vibratory roller; Carry out different gear switches, but its cost is high.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of shifting device for tandem vibratory roller that manufacturing cost is effectively controlled is provided.
The objective of the invention is a kind of shifting device for tandem vibratory roller of realization like this; Comprise speed change control crank, handle controller, gear switch switch and variable traveling pump; The input of said gear switch switch and the output of handle controller join; Proportion magnetic valve coil one end of the output of gear switch switch and variable traveling pump joins; And the OUT+ of the input of handle controller and speed change control crank end joins, the OUT-end of speed change control crank and the common port of handle controller and variable traveling pump the proportion magnetic valve coil other end join, so just formed the shifting apparatus of a double-steel wheeled vibratory roller.
The invention has the beneficial effects as follows:
Shifting device for tandem vibratory roller of the present invention; The vibration hydraulic system that makes double-steel wheeled vibratory roller is under the combination of Variable plunger pump+quantitative piston motor; Also can realize the conversion of gear, quantitatively the piston motor cost has only about half of variable piston motor.Such design one is that manufacturing cost is effectively controlled; The 2nd, realize the shift demand of user to double-steel wheeled vibratory roller.
(4) description of drawings
Fig. 1 is the theory diagram of shifting device for tandem vibratory roller of the present invention.
Reference numeral among the figure:
The proportion magnetic valve coil 4 of speed change control crank 1, handle controller 2, gear switch switch 3, variable traveling pump.
(5) specific embodiment
Referring to Fig. 1, Fig. 1 is the theory diagram of shifting device for tandem vibratory roller of the present invention.Can find out by Fig. 1; Shifting device for tandem vibratory roller of the present invention; The proportion magnetic valve coil 4 that comprises speed change control crank 1, handle controller 2, gear switch switch 3 and variable traveling pump; The output of the input of said gear switch switch 3 and handle controller 2 joins; The one B end of the coil 4 of the output of gear switch switch 3 and variable traveling pump proportion magnetic valve joins; And the OUT+ of the input of handle controller 2 and speed change control crank 1 end joins, and the OUT-end of speed change control crank 1 joins with the A end of the coil 4 of the common port of handle controller 2 and variable traveling pump proportion magnetic valve, has so just formed the shifting apparatus of a double-steel wheeled vibratory roller.
Its effect changes analog quantity electrical signal transfer to variable traveling pump proportion magnetic valve coil 4 signal of (control variables traveling pump discharge capacity) of speed change control crank 1 in same angle output mainly through 3 actions of gear switch switch.One timing of double-steel wheeled vibratory roller engine speed, when gear switch switch 3 was in rabbit crotch (shelves fast) position, speed change control crank 1 was when certain angle; The electric current of output is n (mA); At this moment the coil 4 of variable traveling pump proportion magnetic valve must be electric, and magnetic force pulling valve rod (the control variables traveling pump discharge capacity) action of generation changes the swash plate of variable traveling pump; Make variable walking pump delivery reach Q (ml/r), the travel speed of double-steel wheeled vibratory roller reaches V (km/h); When gear switch switch 3 switches to tortoise crotch (shelves at a slow speed) position; Speed change control crank 1 is when same angle, and the electric current of output is n/2 (mA), and at this moment the coil 4 of variable traveling pump proportion magnetic valve gets; Magnetic force pulling valve rod (the control variables traveling pump discharge capacity) action that produces; The swash plate of variable traveling pump is changed, make variable walking pump delivery reach Q/2 (ml/r), the travel speed of double-steel wheeled vibratory roller reaches V/2 (km/h).Through the gear switch switch, just realized the transforming gear process of double-steel wheeled vibratory roller like this.This device is the variation through pumpage, realizes a process of shift, and is simple and practical easy to operate.
