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 transmissions, comprises electric control equipment, input secondary gear clutch, hydraulic control device, described hydraulic control device comprises two axle gearshift solenoid valves 6, secondary gear switch electromagnetic valve 5, variable speed pump 7, input secondary gear clutch comprises clutch plunger 9, active friction plate 11, driven friction disk 10, Compress Spring 12, described secondary gear switch electromagnetic valve 5 is connected with clutch plunger 9 by oil circuit and accessory, described input secondary gear clutch is installed on the intermediate input axle assembly 8 of planetary transmission, described electric control equipment comprises that two axles improve controller 4, gear approach switch 1, secondary gear switch electromagnetic valve 5, two axle gearshift solenoid valves 6, described gear approach switch 1 is connected with the input port that two axles improve controller 4 by wire harness, secondary gear switch electromagnetic valve 5, two axle gearshift solenoid valves 6 are connected with the output port that two axles improve controller 4 by wire harness respectively, described gear approach switch 1 is arranged in planetary transmission, and described two axles improve controller 4 and adopt single-chip microcomputer.
In conjunction with above-described embodiment, working procedure of the present invention and principle are described below:
Gear approach switch 1 in the present invention receives shift signal in real time, and signal is passed to two axles improvement controller 4, two axles improvement controllers 4 according to this signal judgement shifting state the control of shifting gears by wire harness.In use, secondary gear velocity transducer 2 in two hydrotransmitter planetary transmissions, engine speed sensor 3 also improve controller 4 with two axles and are connected, and to improve controller 4 by two axles, complete two corresponding detecting and control of parameters of hydrotransmitter planetary transmission.
When the state of gear lever handle is when neutral (N), two axles improve controller 4 output high level, thereby the secondary gear switch electromagnetic valve 5 in control hydraulic control device is to input secondary gear clutch feed, hydraulic oil flows in the oil duct of intermediate input axle assembly 8 by the oil duct in torque-converters housing, and then enters into the cavity between clutch plunger 9 and intermediate input axle assembly 8.
Increase along with hydraulic oil pressure, hydraulic oil promotes clutch plunger 9 Compress Springs 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, to input secondary gear 13 lockings, the input one-level gear 14 of now inputting secondary gear 13 and cooperation is with it static.
When gear lever handle is advanced to forward gear (F1) or retreats gear (R) from neutral gear (N), be that operator are while starting to carry out gear shift operation, two axles improve controller 4 output low levels (0V), now secondary gear switch electromagnetic valve 5 quits work, hydraulic oil stops entering into input secondary gear clutch, by variable speed pump 7, inhale the hydraulic oil coming and cannot pass through two axles gearshift solenoid valves 6 to two shaft clutch fuel feeding of planetary transmission inside, and hydraulic oil in input secondary gear clutch is owing to removing the reason of oil sources, hydraulic oil pressure reduces rapidly, under the effect of spring 12 restoring forces, promoting clutch plunger 9 moves right, route by the oil in cavity between clutch plunger 9 and intermediate input axle assembly 8 when oil-filled is discharged to two axles gearshift solenoid valves 6, by two axle gearshift solenoid valves 6, get back in the speed variator system oil sump in hydraulic control system.
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, thereby guarantee in shift process, gearbox input one-level gear 14 and input secondary gear 13 are always in static or lower-speed state, when gearshift finishes, input secondary gear throw-out-of clutch, realizes the normokinetic smooth transfer of planetary transmission.The engineering machinery that said process has been guaranteed the two hydrotransmitter planetary transmissions of the uses such as loader from neutral when advancing or retreat gear, it is a process from static to motion all the time that input one-level gear 14 in planetary transmission and input secondary gear 13 are taken turns, thereby has fundamentally solved the problem that gearshift is impacted.
