The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1 and Fig. 2.
Embodiment 1
A kind of loader-digger of automatically controlled shift control comprises actuating unit, and actuating unit is provided with automatically controlled shift operating device; Automatically controlled shift operating device has gear selector, control actuator, gearbox shifting valve; Central authorities' control box connects gear selector, control actuator, and central control box receives the gear selector signal, and the output control signal drives the control actuator, and the control actuator connects controls the gearbox shifting valve, carries out the automatically controlled gear shift of loader-digger.
The control actuator is high low velocity control actuator and direction control actuator.High low velocity control actuator has valve rod to be connected with direction control actuator to control the gearbox gear-shift valve.There is loader-digger to advance, retreat, stop hydraulic circuit in the gearbox shifting valve.Core of a cable is arranged, transmission of data signals between gear selector, central control box, control actuator.
The concrete structure of present embodiment and the course of work:
Present embodiment adopts automatically controlled shift control technology, and automatically controlled shifting operating device is installed on the loader-digger of traditional counter shaft gearbox, realizes the skill upgrading of hand shift to electronic gear shift with low cost; Utilize the central control system instruction, realize that the machine neutral gear starts.
Automatically controlled shifting operating device is mainly formed gear selector 1, central control box (ECU) 2, height speed control system actuator 3, direction are controlled actuator 4, wire harness 5, gearbox shifting valve 6.
As shown in Figure 2.Automatically controlled shift control: after system connects the DC24V power supply, automatically perform N retaining program (the gear selector places the N position), guarantee that promptly actuator output valve rod is in the stroke meta.
Driver control " gear selector " sends shift signal to " central control box (ECU) ", " ECU " driving " height speed control system/direction control actuator " motion, the conversion of " shift valve " stem position is controlled in the motion of " actuator ", thereby change the duty of " control valve gearbox " hydraulic circuit, the control loader-digger advances, retreats, stops and the gear of advancing.
As Fig. 1, gear selector is installed on the steering column, and the driver can carry out gear shift operation simply and easily.
When loader-digger began operation, system connected power supply, and central control box (ECU) is analyzed according to actuator position, and when actuator during not at the N gear, ECU sends instruction to actuator, and system enters the N shelves automatically and awaits orders.Pull the gear selector handle by front and back and change direction, push away forward, pull back to falling back to advancing.End by rotation gear selector handle changes travel speed.
The electronic shift control system of loader-digger, because of inductive switch is installed in the selector, ECU provides different instructions to be sent to actuator according to different switch on and off, actuator is handled gearbox shifting valve stem movement, make machine be in F or R position, behind selection N retaining, actuator still arrives meta according to the order of speed change after the commutation earlier with actuator motions; Thereby can easily realize automatically controlled self-shifting function accurately.Quoting of this electric shifter makes steering force drop to 6N by 30N, and control run drops to about 40mm from 80mm.And drive range is more accurate.Making common mechanical gear shift gearbox can finish the function of electrically controlled gearbox on the basis cheaply, improved the cost performance of machine greatly like this.
