One parking brake switch S1 is in parallel with the first control switch K1.
Wherein, it is low gear 4 wheel driven valve 110 that low gear gas circuit and precursor gas, which route a valve control, and high gear gas circuit is by a valve control
System is that high gear two drives valve 120.Two valves realize one or the other control, to realize by a change-over switch, i.e. switching switch Q
High gear two drives being switched fast between low gear 4 wheel driven.
The control system of 4 wheel driven truck according to the present invention can eliminate mechanical damage hidden danger and protect the peace of driver and passenger
Entirely.
As shown in connection with 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.
Referring to figs. 1 and 2, the control system 100 for the 4 wheel driven truck that the present invention is implemented by taking 4 wheel driven light truck vehicle as an example,
Its working principle is that: after power switch IG is connected, when switching switch Q drives the second double-throw contact that valve 120 is connected from high gear two
When Q2 switches to the first double-throw contact Q1 being connected with low gear 4 wheel driven valve 110, obtain 4 wheel driven guard relay K1 electric, and make four
Drive guard relay K1 internal switch K10In an ON state, that is, 110 circuit of low gear 4 wheel driven valve has been connected, to make high gear two
Drive switches to low gear 4 wheel driven；When switching switch Q is switched to and high gear from the first double-throw contact Q1 being connected with low gear 4 wheel driven valve 110
Two when driving connected the second double-throw contact Q2 of valves 120,4 wheel driven guard relay K1 obtain it is electric must not electricity, in 4 wheel driven guard relay K1
Portion switch K10It is in an off state, after being only closed the first parking brake switch S1, just can turn on the circuit that high gear two drives valve 120.It is comprehensive
It is upper it is found that be closed in the first parking brake switch S1, i.e., under parked state, using switching switch Q be just able to achieve the drive of high gear two with
Mutually switch between low gear 4 wheel driven.
As shown in table 1, in parked state, three kinds of working conditions of driving states and driving states are switched to by parked state under,
When using switch Q is switched, the high gear two of the control system 100 of 4 wheel driven truck is driven and the mutual handoff relation of low gear 4 wheel driven.
Table 1
As shown in table 1, when switching to driving states by parked state, when the first parking brake switch S1 switchs to disconnect by being closed
Afterwards, 4 wheel driven light truck such as top grade two drive downward driving when, keep driving status have transfer case locking structure guarantee.Four
Light truck vehicle is driven such as in low gear 4 wheel driven downward driving, keep driving status be opened by the first control extension K1 obtain it is electric after, connect it
Circuit can be just maintained under low gear 4 wheel driven.
Under driving states, 4 wheel driven light truck such as when top grade two drives downward driving, when using switch Q is switched, is wanted to be cut
Low gear 4 wheel driven is shifted to, due to the first parking brake switch S1 open circuit, high gear two is driven 120 circuit of valve and is not turned on, thus can not switch over,
To continue that top grade two is kept to drive downward driving.In 4 wheel driven light truck vehicle such as in low gear 4 wheel driven downward driving, when using switching switch Q
When, want to switch it to top grade two drive, driving the first parking brake switch S1 in 120 circuit of valve due to high gear two is open circuit, is made at its
In not on-state, then 4 wheel driven light truck can drive downward driving in low gear two.
When under driving states, it is noted that the gas circuit of high gear valve and low gear valve is moved towards.Table 2 is transfer case in different gas
Functional status implementation of conditions under line state.
Table 2
As shown in table 2, under driving states, in high tap position, high gear valve has gas, when low gear valve is without gas, no tread flaking risk,
In low gear, low gear valve has gas, when high gear valve is without gas, no tread flaking risk.
As shown in connection with fig. 2, the control system 100 of 4 wheel driven truck, further includes: power take-off valve R, power taking valve 130, second are controlled
Make switch K2 and the second parking brake switch S2.
Wherein, one end of power take-off valve R is connected with power switch IG.One end of power taking valve 130 is with power take-off valve R's
The other end is connected.Second control switch K2 has control terminal, and the control terminal of the second control switch K2 is another with power take-off valve R's
End is connected, and one end of the second control switch K2 is connected with the other end of power taking valve 130, another termination of the second control switch K2
Ground.Second parking brake switch S2 is in parallel with the second control 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 vehicle body parking brake switch S2.
According to Fig.2, the control system 100 of 4 wheel driven truck further include: parking brake indicator light L and diode D.Parking brake instruction
One end of lamp L is connected with power switch IG.The cathode of diode D is connected with the other end of parking brake indicator light 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 the power taking under all driving states.
Table 3 is functional status implementation of conditions of the power takeoff under different gas circuit states.
Table 3
Such as table 3 it is found that when being closed power take-off valve, having wind in the case where power taking valve 130 has gas only under driving states
Danger, other devoids of risk.
Furthermore it is also possible to which remote control oil door carries out power taking, principle is as shown in figure 3, it is found that stop idling shape in vehicle
Under state, start long-range throttle control switch, controlled by long-range hand throttle, controls engine speed range 750-3000r/
min.The control system of 4 wheel driven truck according to an embodiment of the present invention can eliminate mechanical damage hidden danger and protect driver and passenger's
