Accompanying drawing explanation
Fig. 1 is the circuit diagram of telescopic arm forklift transfer case shift control apparatus in the utility model embodiment.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Shown in Figure 1, the utility model embodiment provides a kind of telescopic arm forklift transfer case shift control apparatus, comprise ECU controller, selector switch SA9, gearshift controller, transfer case speed probe, low gear solenoid valve, high gear solenoid valve, gearshift tutorial light, relay K 14, gearshift put in place tutorial light and diagnostor, ECU controller is connected with gearshift controller by selector switch SA9, gearshift controller respectively with transfer case speed probe, low gear solenoid valve, high gear solenoid valve, gearshift tutorial light is connected, ECU controller is also connected by relay K 14 and the gearshift tutorial light that puts in place, diagnostor is connected with ECU controller, ECU controller is also connected with outside computer.
The utility model embodiment also provides a kind of telescopic arm forklift, comprise telescopic arm forklift transfer case and telescopic arm forklift transfer case shift control apparatus, telescopic arm forklift transfer case shift control apparatus comprises ECU controller, comprise selector switch, gearshift controller, transfer case speed probe, low gear solenoid valve, high gear solenoid valve, gearshift tutorial light, relay, gearshift put in place tutorial light and diagnostor, ECU controller is connected with gearshift controller by selector switch, described gearshift controller respectively with transfer case speed probe, low gear solenoid valve, high gear solenoid valve, gearshift tutorial light is connected, ECU controller is also connected by relay and the gearshift tutorial light that puts in place.Diagnostor is connected with ECU controller, and ECU controller is also connected with outside computer.
The utility model embodiment's working principle is elaborated as follows:
The utility model embodiment transmits tach signal by transmission system and passes on gearshift control panel, by gearshift control panel control gearshift valve member, drives shift cylinder, stirs transfer case shifting fork and realizes gearshift control; After gearshift, by shift fork, transmit position signal to ECU controller, by ECU controller, control the signal that puts in place of shifting gears, the safety locking state of gearshift is monitored in real time, guarantee the Security that telescopic arm forklift travels.When the program of ECU controller makes the 5th port of ECU controller have electrical signal, carry out parking control, transfer case gearshift puts in place, and the signal that will put in place passes to relay K 14, the protection of shifting gears.When gearshift puts in place, the transfer case gearshift sensor conducts that puts in place, makes relay K 14 have electricity, and break contact, makes the 5th port power-off of ECU controller; When gearshift is not when put in place, the transfer case level sensor of shifting gears disconnects, and relay K 14 does not have electricity, makes the 5th port of ECU controller have electrical signal, produces parking and controls.At this moment, need to again shift gears brake off, therefore reach the Security of car load running process and gearshift.
While shifting gears, control selector switch SA9 in practical operation, make the J1:23 interface of gearshift controller inside or J1:14 interface have electricity, produce gearshift control signal, transfer case speed probe passes the signal along to its inner control panel, by the conversion of chip, produces voltage signal.Suppose that VCC has electricity, signal passes to triode, and when transfer case has speed, voltage signal has electricity, and the emitter of triode and collector electrode disconnect; When transfer case speed is 0, voltage signal is 0, and the at this moment emitter and collector conducting of triode, has 24V voltage to open low gear solenoid valve, thereby drives shift cylinder to realize gearshift, by Control LED lamp, realizes gear and selects indication.Through experimental test, the utility model stable performance, use reliably, have met the travel requirement of car load under different pavement conditions preferably.
