Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
Control system and 4 wheel driven truck below in conjunction with accompanying drawing description 4 wheel driven truck according to embodiments of the present invention.
Fig. 1 is the structured flowchart of the control system of 4 wheel driven truck according to an embodiment of the invention.
As it is shown in figure 1, the control system 100 of 4 wheel driven truck according to an embodiment of the invention, including: switching switch Q,
Low gear 4 wheel driven valve 110, high gear two are driven valve 120, first and are controlled switch K1 and the first parking brake switch S1.
Wherein, switching switch Q has the first contact Q0, the first double-throw contact Q1 and the second double-throw contact Q2, the first contact
Q0 is connected with on and off switch IG.One end of low gear 4 wheel driven valve 110 is connected with the first double-throw contact Q1 of switching switch Q, high gear two
The second double-throw contact Q2 of one end and switching switch Q of driving valve 120 is connected.First controls switch K1 has control end, the first control
The end that controls of system switch K1 is connected with the first double-throw contact Q1 of switching switch Q, and first controls one end of switch K1 respectively with low
The other end that the other end of gear 4 wheel driven valve 110 drives valve 120 with high gear two is connected, and first controls the other end ground connection of switch K1.The
It is in parallel that one parking brake switch S1 and first controls switch K1.
Wherein, low gear gas circuit route an i.e. low gear 4 wheel driven valve 110 of valve control with precursor gas, and high gear gas circuit is by a valve control
System i.e. high gear two drives valve 120.Two valves pass through a permutator, i.e. switching switch Q, it is achieved either-or control, thus realize
High gear two drives being switched fast between low gear 4 wheel driven.
The control system of the 4 wheel driven truck according to the present invention, it is possible to eliminate mechanical damage hidden danger and the peace of protection driver and crew
Entirely.
Shown in Fig. 2, switching switch Q can be hand control switch, and the first control switch K1 can be relay, i.e.
4 wheel driven guard relay K1.First parking brake switch S1 is chassis parking brake switch S1.
Shown in Fig. 1 and Fig. 2, the control system 100 of 4 wheel driven truck that the present invention implements as a example by the light truck-type of 4 wheel driven,
Its operation principle is: after on and off switch IG connects, when switching switch Q is from driving the second double-throw contact that valve 120 is connected with high gear two
When Q2 switches to the first double-throw contact Q1 being connected with low gear 4 wheel driven valve 110, make 4 wheel driven guard relay K1 obtain electric, and make four
Drive guard relay K1 internal switch K10In an ON state, i.e. connect low gear 4 wheel driven valve 110 loop, so that high gear two
Drive and switch to low gear 4 wheel driven；When switching switch Q switches to and high gear from the first double-throw contact Q1 being connected with low gear 4 wheel driven valve 110
Two when driving the second double-throw contact Q2 that valve 120 is connected, 4 wheel driven guard relay K1 obtain electric must not electricity, in 4 wheel driven guard relay K1
Portion switch K10It is off, after only closing the first parking brake switch S1, just can turn on high gear two and drive the loop of valve 120.Combine
Upper understand, switch S1 Guan Bi at the first parking brake, i.e. under parked state, use switching switch Q could realize high gear two drive with
Mutually switch between low gear 4 wheel driven.
As shown in table 1, at parked state, transferred under driving states and three kinds of duties of driving states by parked state,
When using switching switch Q, the high gear two of the control system 100 of 4 wheel driven truck drives handoff relation mutual with low gear 4 wheel driven.
Table 1
As shown in table 1, when being transferred to driving states by parked state, transferred to disconnection when the first parking brake switchs S1 by Guan Bi
After, when 4 wheel driven gently blocks as driven lower traveling high-grade two, it keeps transport condition to have transfer case latch-up structure to ensure.Four
Drive light truck-type as under low gear 4 wheel driven travel time, its keep transport condition be by first control open extension K1 obtain electric after, connect it
Loop, just can be maintained under low gear 4 wheel driven.
Under driving states, 4 wheel driven gently blocks as when high-grade two drive lower traveling, when using switching switch Q, wants to be cut
Shifting to low gear 4 wheel driven, due to the first parking brake switch S1 open circuit, high gear two is driven valve 120 loop and is not turned on, thus cannot be carried out switching,
High-grade two are kept to drive lower traveling continuation.When the light truck-type of 4 wheel driven such as traveling under low gear 4 wheel driven, when using switching switch Q
Time, wanting to switch it to top grade two drive, the first parking brake switch S1 driven in valve 120 loop due to high gear two is open circuit so that it is place
In not on-state, then 4 wheel driven gently card can drive lower traveling in low gear two.
Time under driving states, it is noted that high gear valve and the gas circuit trend keeping out valve.Table 2 is that transfer case is at different gas
Functional status implementation of conditions under line state.
Table 2
As shown in table 2, under driving states, when high tap position, high gear valve has gas, when keeping out valve depletion of QI, without tread flaking risk,
When keeping out, keeping out valve has gas, during high gear valve depletion of QI, without tread flaking risk.
Shown in Fig. 2, the control system 100 of 4 wheel driven truck, also include: power take-off valve R, power taking valve 130, second are controlled
System switch K2 and the second parking brake switch S2.
Wherein, one end of power take-off valve R is connected with on and off switch IG.One end of power taking valve 130 is with power take-off valve R's
The other end is connected.Second controls switch K2 has a control end, second control switch K2 control another of end and power take-off valve R
End is connected, and second one end controlling switch K2 is connected with the other end of power taking valve 130, and second controls another termination of switch K2
Ground.It is in parallel that second parking brake switch S2 and second controls switch K2.Second control switch K2 can be relay, and Fig. 2 shows it
For power taking guard relay K2.Second parking brake switch S2 can be that vehicle body parking brake switchs S2.
According to Fig. 2, the control system 100 of 4 wheel driven truck also includes: parking brake display lamp L and diode D.Parking brake indicates
One end of lamp L is connected with on and off switch IG.The negative electrode of diode D is connected with the other end of parking brake display lamp L, the sun of diode D
Pole is connected with the other end of power taking valve 130.In conjunction with as shown in Figure 2, power takeoff can power taking under all driving states.
Table 3 is power takeoff functional status implementation of conditions under different gas circuit states.
Table 3
As table 3 understands, only under working as at driving states, during Guan Bi power take-off valve, under power taking valve 130 has gas, there is wind
Danger, other devoids of risk.
Furthermore it is also possible to remote control oil door carries out power taking, its principle is as shown in Figure 3, it is known that, stop idling shape at car load
Under state, start long-range Throttle Opening Control switch, be controlled by long-range hand throttle, control engine speed range 750-3000r/
