The control assembly is connected with the compressed air reservoir. A piston is arranged inside the fuel-cutoff cylinder. The protruding end of the piston is connected with the fuel-cutoff handle which pushes a throttle lever, and the other end thereof communicates with the control assembly. The fuel-cutoff shutdown device adopts the fuel-cutoff cylinder to drive the fuel-cutoff handle to control the fuel supply of the oil pump of the engine and adopts the compressed air as driving power for the fuel-cutoff handle, and has the advantages of flexible stroke of the push rod, good adaptability and sufficient power.
Description
Technical field
The utility model relates to a kind of engine shutdown device, relates in particular to a kind of oil-break arresting gear that uses the electric control element.
Background technique
At present, vehicular engine uses pure electric halt mode mostly.The device of this pure electric halt mode, mainly by coil and unshakable in one's determination the composition, coil gets during work; iron core stretches out forward under the effect of Ampere force; in order to produce the power of stretchy throttle control handle, coil is done greatlyyer usually, just can make iron core that bigger pulling force is arranged.Because of at first in a flash the need bigger electric current of bigger coil in this device action generation, circuit then may transship and burn if protection is improper.A little fuel oil that high temperature, the spark that circuit burnout produces even the Engine Surface of might igniting splash causes the firing accident of car load, causes great potential safety hazard.
Summary of the invention
In order to overcome the above-mentioned defective of prior art, the motor oil-break arresting gear that provides a kind of operating current little, safe is provided the purpose of this utility model.
For achieving the above object; the utility model provides a kind of motor oil-break arresting gear; comprise control unit, oil-break cylinder, oil-break handle and compressed air reservoir; described control unit is connected with described compressed air reservoir; be provided with piston in the described oil-break cylinder; the external part of this piston connects the oil-break handle that promotes throttle control handle, and the other end is connected with described electric controling assembly.Described control unit is controlled this oil-break cylinder, spurs this oil-break handle to the oil-break position, makes oil pump for engine stop oil spout.
Described control unit comprises solenoid valve, control switch and the power supply that connects with serial fashion, and described solenoid valve is by the intracavity inter-connection of pneumatic tube, air inlet transit joint and described oil-break cylinder.
Be provided with suction port on described oil-break cylinder, described suction port is connected with described air inlet transit joint.
Described solenoid valve is a two-position three way magnetic valve.Described control switch is the oil-break control switch.
The utility model motor oil-break arresting gear is controlled compressed-air actuated turnover with solenoid valve, uses the driving force of air pressure as throttle control handle.Driving the oil-break handle with the oil-break cylinder and control the oil pump for engine fuel cut-off, is oil-break lever drive power with pressurized air, and the stroke of push rod is comparatively flexible, and adaptability is strong, the power abundance.Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, the operating current of whole device only need drive solenoid valve, does not need directly to drive fuel cut-off handle, and required operating current is less;
2, can under situation about losing efficacy, guarantee Security;
3, with pressurized air be the throttle control handle driving force, the stroke of push rod is comparatively flexible, and adaptability is strong, the power abundance.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3; the utility model motor oil-break arresting gear; comprise control unit, oil-break cylinder 1, oil-break handle 8 and compressed air reservoir 9, control unit comprises solenoid valve 3, control switch 5 and the power supply that connects with serial fashion, and solenoid valve is a two-position three way magnetic valve.A blowing mouth of solenoid valve 3 is communicated with and then is communicated with oil-break cylinder 1 inner chamber by pneumatic tube, air inlet transit joint (not shown) with suction port 10 on the oil-break cylinder 1, and the suction port of solenoid valve 3 is connected with compressed air reservoir 9.Compressed air reservoir 9 provides pressurized air by solenoid valve 3 to oil-break cylinder 1.
Be provided with pistons reciprocating pull bar 6 in the oil-break cylinder 1, the external part of this piston pulling rod 6 connects the oil-break handle 8 that promotes throttle control handle.Control unit is controlled this oil-break cylinder 1, spurs this oil-break handle 8 to the oil-break position, makes oil pump for engine stop oil spout.
When automobile need be shut down; closed control switch 5; solenoid valve 3 coils are in "on" position; iron core in the middle of the coil is blocked relief opening 2 under the effect of Ampere force, open suction port 7 simultaneously; pressurized air enters oil-break cylinder 1 and promotes piston pulling rod 6 and moves (Fig. 3 shows that pull bar is toward moving right) toward oil-break cylinder direction in the gas holder 9; this piston pulling rod 6 spurs oil-break handle 8 then to the oil-break position, makes oil pump stop oil spout, engine misses.
After treating that motor is flame-out fully, open control switch 5, solenoid valve 3 coil blackouts, iron core resets under the effect of spring, blocks suction port 7, opens relief opening 2.Gas is discharged from relief opening 2.After gas is discharged, be subjected to oil-break cylinder medi-spring pulling force, the piston in the oil-break cylinder drives pull bar 6 direction outside cylinder and moves, and oil-break handle 8 is got back to initial position.
Wire harness plug 4 above the oil-break cylinder 1 is connected to power supply, and solenoid valve 3 and power supply and control switch 5 are connected with serial fashion.As shown in Figure 3, a cylinder air inlet 10 is arranged on the oil-break cylinder 1, the air inlet transit joint is installed on the cylinder air inlet 10, and solenoid valve is connected by air inlet transit joint and oil-break cylinder 1, with compressed air delivery in the gas holder 7 in the oil-break cylinder.The oil-break arresting gear generally is installed on the oil pump, fixes with support.Pull bar 6 and oil-break handle 8 tighten by bolt and link to each other, so that pull bar pulling oil-break handle during work.
Because the electric current of whole system only need drive solenoid valve, required electric current is less, has solved the defective of common oil-break arresting gear, realizes using little electric current just can drive the oil-break arresting gear of oil-break handle, and the Security of system improves greatly; Simultaneously, use compressed air, the stroke of pull bar is comparatively flexible, and adaptability is strong.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
