Description
Technical field
The invention belongs to engineering machinery and automation field, specifically, particularly relate to a kind of shift control apparatus based on two hydrotransmitter planetary transmission.
Background technique
Loader is mainly used in spading operation and loading operation, for ensure operation efficiently carry out need to carry out frequently starting to walk → stopping, advance → retreat and shift gears, therefore loading machine gearbox shift control system just seems particularly important, is such as contained in the engineering machinery such as the loader of planetary mechanical gear box.
Loader planetary mechanical gear box shift control system is generally primarily of gear lever handle, flexible axle, gearshift control valve, transmission system composition, loader is in gearbox shifting process, especially start to walk, in accelerating process, due to vehicle body weight, moment of torsion is large, in traditional shift process, when changing to another one gear from a gear, owing to experienced by neutral position, gearbox input one-level now, secondary gear assembly is under the driving of torque-converters two-stage turbine, be in High Rotation Speed, rotary inertia is larger, in target gear engagement process, gearbox input one-level, secondary gear assembly moment transferring power is on shift gear, therefore larger impact is created, the gearbox life-span is affected greatly, also had a strong impact on travelling comfort and handling simultaneously.
For solving the large problem of loader planetary transmission shift shock, the scheme of mainly mechanical local improvement conventional at present, namely by improving gear spring stiffness, optimize relating to and widening, shorten the series of measures such as oil charging-discharging oil duct of speed change valve inner pressure relief valve, although gear boosting characteristic curve is improved, the problem of shift shock is improved and not obvious.Current construction industry is good solution not.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment: a kind of shift control apparatus based on two hydrotransmitter planetary transmission, comprises electric control equipment, input secondary gear clutch, hydraulic control device, described hydraulic control device comprises variable speed pump 7, input secondary gear clutch comprises clutch plunger 9, active friction plate 11, driven friction disk 10, Compress Spring 12, described input secondary gear clutch is installed on the intermediate input axle assembly 8 of planetary transmission, described electric control equipment comprises two axis controllers 4, two axle gearshift solenoid valves 6, secondary gear switch electromagnetic valve 5, gear proximity switch 1, described secondary gear switch electromagnetic valve 5 is connected with clutch plunger 9 by oil circuit and accessory, described gear proximity switch 1 is connected by the input port of wire harness with two axis controllers 4, secondary gear switch electromagnetic valve 5, two axle gearshift solenoid valves 6 are connected respectively by the output port of wire harness with two axis controllers 4, described gear proximity switch 1 is arranged in planetary transmission, and described two axis controllers 4 adopt single-chip microcomputer.
In conjunction with above-described embodiment, to working procedure of the present invention and principles and methods as follows:
Gear proximity switch 1 real-time reception shift signal in the present invention, and signal is passed to two axis controller 4, two axis controllers 4 by wire harness judge shifting state according to this signal and carry out gearshift to control.In use, secondary gear velocity transducer 2 in two hydrotransmitter planetary transmission, engine speed sensor 3 are also connected with two axis controllers 4, to be completed the corresponding detecting and control of parameter of two hydrotransmitter planetary transmission by two axis controllers 4.
When the state of gear lever handle is in neutral (N), two axis controllers 4 export high level, thus the secondary gear switch electromagnetic valve 5 in hydraulic control control gear is to input secondary gear clutch feed, hydraulic oil is flowed in the oil duct of intermediate input axle assembly 8 by the oil duct in converter cover, and then enters into the cavity between clutch plunger 9 and intermediate input axle assembly 8.
Along with the increase of hydraulic oil pressure, hydraulic oil promotes clutch plunger 9 Compress Spring 12 and is moved to the left, until clutch plunger 9 compresses driven friction disk 10, and make it to compress with active friction plate 11, secondary gear 13 locking will be inputted, namely now input secondary gear 13 and the input one-level gear 14 that coordinates with it is static.
When gear lever handle is advanced to forward gear (F1) or retrogressing gear (R) from neutral (N), namely when operator start to carry out gear shift operation, two axis controller 4 output low levels (0V), now secondary gear switch electromagnetic valve 5 quits work, hydraulic oil stops entering into input secondary gear clutch, inhaling by variable speed pump 7 hydraulic oil come cannot by the two shaft clutch fuel feeding of two axles gearshift solenoid valves 6 to planetary transmission inside, and the hydraulic oil inputted in secondary gear clutch is owing to removing the reason of oil sources, hydraulic oil pressure reduces rapidly, under the effect of spring 12 restoring force, promote clutch plunger 9 to move right, oil in cavity between clutch plunger 9 and intermediate input axle assembly 8 is discharged to two axles along route time oil-filled to shift gears solenoid valve 6, got back in the speed variator system oil sump in hydraulic control system by two axle gearshift solenoid valves 6.
The present invention is by controlling the input secondary gear clutch on intermediate input axle assembly 8, realize the braking of gearbox two-stage turbine and throw off, thus guarantee in shift process, gearbox input one-level gear 14 and input secondary gear 13 are always in static or lower-speed state, at the end of gearshift, input secondary gear throw-out-of clutch, realizes the normokinetic smooth transfer of planetary transmission.Said process ensure that loader etc. uses the engineering machinery of two hydrotransmitter planetary transmission when from neutral to advance or retrogressing gear, input one-level gear in planetary transmission 14 and input secondary gear 13 take turns be all the time one from static to the process of motion, thus fundamentally solve the problem of shift shock.
