Abstract
An interlocking device between the vehicle and the power take-off includes a gas source, a relay valve, a directional valve, a cylinder, a manual valve, a relay valve and a composite brake chamber. The device is characterized in that: the gas source is respectively connected with the relay valve, the manual valve and the relay valve; the gas source is connected with the relay valve, the relay valve is connected with the directional valve, the directional valve is connected with the cylinder, the gas source is connected with the manual valve, the gas source is connected with the relay and the relay is connected with the composite brake chamber.
Description
Technical field:
The utility model relates to a kind of vehicle driving and power taking interlock.
Background technology:
At present, domestic goods carrying vehicle power taking all is to adopt manual control with the driving interlocking, like this when vehicle driving such as power takeoff work meeting bring danger to the operator.
Summary of the invention:
The purpose of this utility model has provided a kind of control in power taking increases by a relay valve in the gas circuit, control by air pressure with the generation of braking during standstill loop is related, but just power taking when realizing Parking, out-of-action a kind of vehicle driving of power takeoff and power takeoff interlock during driving are to overcome above-mentioned deficiency.
The purpose of this utility model is realized by following technical scheme:
A kind of vehicle driving and power taking interlock, comprise source of the gas, relay valve, change-over valve, cylinder, hand brake valve, relay valve, composite brakig air chamber, be characterized in: source of the gas is connected with relay valve, hand brake valve, relay valve respectively, source of the gas is connected with relay valve, relay valve is connected with change-over valve, and change-over valve is connected with cylinder, and source of the gas is connected with hand brake valve, source of the gas is connected with relay valve, and relay valve is connected with the composite brakig air chamber.
Adopt the utility model vehicle driving and the alternative original manual control of power takeoff interlock, improved the reliability of control, completely abolish maloperation, increased the safety of operating in the power takeoff process, in power takeoff control gas circuit, increase by a relay valve, produce related with the braking during standstill loop, when there is air pressure in the braking during standstill loop, there is not air pressure in the power takeoff control gas circuit, power takeoff can not be worked, when the braking during standstill loop does not have air pressure, in the power takeoff control gas circuit air pressure is arranged, this moment, power takeoff can be worked.
Description of drawings:
Fig. 1 is the signal of the utility model integral structure.
Below in conjunction with accompanying drawing the utility model is further described:
The specific embodiment:
Embodiment:
As shown in Figure 1, the utility model is made up of source of the gas 5, relay valve 6, change-over valve 7, cylinder 8, hand brake valve 9, relay valve 10, composite brakig air chamber 11, be characterized in: source of the gas 5 is connected with relay valve 6, hand brake valve 9, relay valve 10 respectively, source of the gas 5 is connected with relay valve 6, relay valve 6 is connected with change-over valve 7, and change-over valve 7 is connected with cylinder 8, and source of the gas 5 is connected with hand brake valve 9, source of the gas 5 is connected with relay valve 10, and relay valve 10 is connected with composite brakig air chamber 11.Source of the gas 5 is given hand brake valve 9, relay valve 10, relay valve 6 air feed respectively, and source of the gas 5, relay valve 6, change-over valve 7, relay valve 10 are contained on the vehicle longeron, and composite brakig air chamber 11 is contained on the back axle, and hand brake valve 9 is contained in the operator's compartment, and cylinder 8 is contained on the power takeoff.
During driving, hand brake valve 9 is in free state, and admission port (1 mouthful) communicates with air extractor duct (2 mouthfuls), and promptly the control mouth of relay valve 10 (4 mouthfuls) has air pressure, the admission port of relay valve 10 (1 mouthful) communicates with air extractor duct (2 mouthfuls), and there is air pressure the spring energy-storage chamber of composite brakig air chamber 11.This moment, the control mouth (4 mouthfuls) of relay valve 6 had air pressure, and the air extractor duct of relay valve 6 (2 mouthfuls) communicates (promptly communicating with atmosphere) with exhausr port (3 mouthfuls), and the admission port of 3/2 change-over valve 7 does not have air pressure, and power takeoff cylinder 8 can not be worked at this moment.
During Parking, the hand brake valve 9 of leaving behind, air extractor duct (2 mouthfuls) is that atmosphere communicates with exhausr port (3 mouthfuls), be the no air pressure of control mouth (4 mouthfuls) of relay valve 10, the air extractor duct of relay valve 10 (2 mouthfuls) communicate with exhausr port (3 mouthfuls) (promptly communicating) with atmosphere, the spring energy-storage chamber venting of composite brakig air chamber 11, automobile is in the Parking state.This moment relay valve 6 the no air pressure of control mouth (4 mouthfuls), the admission port of relay valve 6 (1 mouthful) communicates with air extractor duct (2 mouthfuls), then the admission port of 3/2 change-over valve 7 has air pressure, by controlling two positions of 3/2 change-over valve 7, whether the work of realization power takeoff cylinder 8 to be.
During power taking, identical when then the action of each valve is just with driving if will drive a vehicle and promptly unclamp hand brake valve 9, this moment, the power takeoff cylinder 8 quit work, and automobile enters driving states, locking the work of power takeoff.
