Description

Tooth shaft type shorting-out device

Technical field

The utility model relates to a kind of diesel engine shorting-out device, a kind of tooth shaft type shorting-out device of more specifically saying so.

Background technique

As everyone knows, the flame-out of diesel engine is the throttle swing handle that spurs on its oil pump, by the complicated mechanical transmission device, promotes the tooth axle and does axial motion, thereby drive the rotation of each oil nozzle gear, blocks the fuel feeding tank circuit of oil nozzle, makes diesel engine flame-out.For the diesel engine on the automobile, the mode of pulling throttle swing handle pulls with shorting-out device draws two kinds.Pull and connect a stay cord exactly on the throttle swing handle, the other end of stay cord is fixed in the operator cabin, goes pulling by the driver with hand when flame-out, and its drawback is the original backwardness of mode of operation.It is exactly to adopt motor or electromagnetic induction to produce pulling force that shorting-out device draws, remove to spur the throttle swing handle by stay cord, go control by the driver by electric switch when flame-out, though this kind mode goes a step further before pulling, but its deficiency is: the distance that the throttle swing handle moves when 1, flame-out, from idling to closing the distance of throttle about will mobile 3cm fully; 2, stay cord is long, needs the long stay cord of 50cm-100cm to come transmission; 3, the pulling force loss is big, and shorting-out device will overcome the complicated gearing friction power and the elastic force of return spring, the power that approximately will consume 40N-70N.These above-mentioned deficiencies cause shorting-out device have consumed power big, take up room big and the drawback of trouble be installed.

Summary of the invention

The purpose of this utility model provide a kind of energy-conservation, take up room tooth shaft type shorting-out device little.

In order to realize above-mentioned purpose, the tooth shaft type shorting-out device that is provided, comprise the electromagnetic valve body that has a central bore, the electromagnetic coil that is wrapped on the coil rack is housed in the electromagnetic valve body, its structural feature is the soft iron bar that return spring is housed in central bore and is abutted against with return spring, the overhanging end of this soft iron bar is connected oil pump tooth axle, a side of oil pump tooth axle is provided with a tooth, the axle tooth can mesh with the spindle gear that is contained on the oil nozzle mandrel, electromagnetic coil is connected on the output terminal of controller, and this controller is to provide power supply by automobile storage battery, the electronic switching circuit of control signal is provided by the automobile flameout signaling line.

Above-mentioned axle tooth is to be distributed on the side of oil pump tooth axle by section, and the quantity of section is identical with the quantity of oil nozzle.

Above-mentioned electronic switching circuit comprises power control circuit and the electromagnetic coil circuit for controlling electricity turning that is connected with power control circuit, the coil of first relay that includes power supply switch tube in the power control circuit and connect and the self-holding contact of first relay with this power supply switch tube, the coil of second relay that includes electromagnetic coil power-on switch pipe in the electromagnetic coil circuit for controlling electricity turning and connect with this electromagnetic coil power-on switch pipe, the normally opened contact of second relay is connected in the current supply circuit of electromagnetic coil, the coil of electromagnetic coil power-on switch pipe and second relay be connected in series a little on be connected to delay circuit, the output terminal of this delay circuit is connected with the silicon controlled trigger electrode, controllable silicon is connected between the output terminal of the base stage of power supply switch tube and electromagnetic coil power-on switch pipe, and the base stage of the coil of first relay and electromagnetic coil power-on switch pipe constitutes with the automobile flameout signaling line and is electrically connected.

The working principle of tooth shaft type shorting-out device provided by the utility model is: behind the automobile starting, maintain positive voltage on the automobile flameout signaling line, this positive voltage gets the coil of first relay, its self-holding contact closure, automobile storage battery is to power supply switch tube and the power supply of electromagnetic coil power-on switch pipe, power supply switch tube conducting this moment, and electromagnetic coil power-on switch pipe is to be ended by the high petential that the automobile flameout signaling line provides owing to its base stage, the coil losing electricity of second relay, its normally opened contact is in off state, no current passes through in the electromagnetic coil, do not produce induction field, soft iron bar and oil pump tooth axle still remain on the state that throttle is opened under the effect of return spring; After flame-out signaling line is left in the rotation of automobile key inhour, the base stage of electromagnetic coil power-on switch pipe becomes low potential, the conducting of electromagnetic coil power-on switch pipe, electric, its normally opened contact closure that the coil of second relay gets, there is electric current to pass through in the electromagnetic coil, produce induction field, this induction field attracts the soft iron bar to move inward, driving oil pump tooth axle synchronous shift rotates, oil pump tooth axle drives the oil nozzle mandrel by spindle gear and rotates, cut off the path of oil hole and oil duct groove, close throttle, finish flame-out; The conducting of electromagnetic coil power-on switch pipe, electric capacity in the delay circuit is charged, when the voltage on the electric capacity is charged to the silicon controlled trigger voltage value, the controllable silicon conducting, the base stage of power supply switch tube becomes high petential, power supply switch tube ends, the coil losing electricity of first relay, its self-holding contact disconnect, the cut off the electricity supply power supply of switching tube and electromagnetic coil power-on switch pipe, make the entire controller outage, no current passes through in the electromagnetic coil, and soft iron bar and oil pump tooth axle remain on the state that throttle is opened again under the effect of return spring.

Learn by above narration, tooth shaft type shorting-out device provided by the utility model, because the axle tooth on the oil pump tooth axle can mesh with the spindle gear that is contained on the oil nozzle mandrel, this tooth shaft type shorting-out device can be fixed on the oil pump, because the soft iron bar directly links to each other with oil pump tooth axle, under the control of controller, finish flame-out action again, therefore have following beneficial effect: 1, compact structure, it is little to take up room, easy for installation; 2, simplified driving mechanism, reduced frictional force, compared with the dragline type shorting-out device, the electric energy loss of flame-out operation reduces more than 50%, and energy-saving effect is remarkable.
