Abstract
Via providing a set of electric controlling and operating throttle control devices for a throttle operating lever and a pressure reduction valve operating lever, an internal combustion engine is caused to have three oil supply states corresponding to the norm rotation speed, the idle speed and the stoppage; therefore, the engine can be remotely controlled. A throttle actuating mechanism is composed of an electric motor, a couple of engaged gears and a crank connecting rod mechanism. A control return circuit adopts two blocks of controlled silicon to control the electric motor to positively rotate and reversely rotate to enhance the throttle or throttle down the throttle. A transistor is near the switch to be used for stopping the electric motor. The controlling circuit has the function of sequential control; the stoppage only can be carried out after the engine lies in the idle speed.
Description
The utility model relates to the throttle control of internal-combustion engine, particularly a kind of throttle control by electric wiring and mechanical composition.
Existing internal-combustion engine all is by manual operation, realizes shutting down, starts shooting and the control accelerator open degree.For vibration roller road roller one class machine, because of the vibration roller apart from each other at operator cabin and rear portion, driver must before and after the operation of running, very inconvenient.
The purpose of this utility model is the accelerator control device that a kind of electric control operation will be provided, and explosive motor is had and rated speed, idling and the corresponding three kinds of fuel feeding states of shutdown, thereby can control motor easily at a distance.
Solution of the present utility model is: QUADRANT and decomp lever to existing internal-combustion engine are set up a cover control gear, and it has:
(1) throttle operation mechanism

(3.4) time delay relay is used for breaking circuit electromagnet is resetted.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is an electric wiring schematic diagram of the present utility model.
Fig. 2 is an overall structure schematic representation of the present utility model.
Fig. 3 is the Throttle Opening Control mechanism map.
Fig. 4 is the view of Fig. 3 along the A-A section.
Referring to Fig. 1, motor 1 is controlled startup respectively by controllable silicon 3,4, and is shut down near switch 8,10 controls by transistor.After connecting power supply, be on state near switch 8, the J1 make contact.And near switch 10 and limiting stopper opposite position at off state, J2 opens the contact.Strengthen instruction for throttle of controllable silicon 3 trigger electrodes through signal input part 31, the controllable silicon conducting, the normally opened contact closure of J3, normally-closed contact is opened simultaneously, cuts off another road power supply.To power cathode, start working by motor 1 through J3, motor 1, J4 for electric current, after worm and worm gear slow down, as shown in Figure 3, drives small gear 20 and gearwheel 21 rotations again.The connecting rod of adjustable eccentric distance is housed on the gearwheel, and wherein connecting rod 11 drives QUADRANT 12 swings, and throttle is opened greatly.When gearwheel 21 turns over several angle, when throttle reaches the precalculated position, when the spacing slug 14 on it and transistor contactless proximity switch 8 are relative, disconnect near switch 8, J1 opens the contact, circuitry cuts, motor stall.Like this, motor just is in rated speed state, proper functioning.At this moment controllable silicon 3 blocking-up, the J3 contact resets.After limiting stopper on the gearwheel left, near just conducting of switch 10, the normally opened contact closure of J2 was cut off shutdown circuit simultaneously.
When operation mechanism need quit work, should make diesel engine be in idling mode, turn down the throttle instruction at this moment for 32 1 of governor circuit input ends, controllable silicon 4 triggering and conducting then, the normally opened contact closure of J4, normally-closed contact is opened.Be on state near switch 10, J2 normally opened contact closure, motor counterrotating work.Drive aforesaid operations mechanism throttle turned down, when spacing slug 14 with, turn-off when relative near switch 10 near switch 10, the disconnection of J2 contact, motor quits work, controllable silicon 4 is blocked, the J4 contact resets, motor is in idling mode.All are returned to original state, and the J2 normally opened contact links to each other the conducting shutdown circuit with time delay relay SJ.
Engine misses are shut down, give a shutdown command, controllable silicon 5 triggering and conducting by signal input part 33.Electric current by time relay coil SJ and contactor J5 in parallel, makes J5 normally opened contact closure again through normally-closed contact, the controllable silicon 5 of time delay relay SJ, electromagnet 9 actions.Time relay sj picks up counting simultaneously, and the time-delay back disconnects.Electromagnetic actuation drags leverage 15 and drives 16 swings of speed regulator decomp lever, and oil pressure reduces, and fuel cut-off makes diesel engine 17 flame-out shutdown.
Among Fig. 2, electric wiring 19 and reducing gear 70 are contained on the support of diesel engine 17, and power supply is introduced by the instrument panel 18 of diesel engine 17.
Throttle Opening Control mechanism as shown in Figure 3, Figure 4.Motor drives worm and gear (not drawing among the figure) slows down through gear 20,21 again.Gearwheel 21 is equipped with an eccentric mounting 22 as crank disc on it, eccentric mounting is provided with positioning hole 23, is used to adjust throw of eccentric.In the connecting rod 11 1 end patchholes 23, the other end links to each other with QUADRANT 12.Metal limiting stopper 14 also is housed on the gear 21, and 8,10 of transistor contactless proximity switch are contained on the fixed plate 24 of gear side.Can adjust the position along a straight trough near switch.The adjusting of throttle size mainly by the throw of eccentric coarse adjustment with realize jointly near the fine setting of switch.When motor driven gear 21 slowly rotated, connecting rod 11 just drove 12 swings of throttle operation bar, and throttle is opened greatly gradually.When the limiting stopper on the gear 21 14 forwards to and when relative, cuts off electric motor loop near switch near switch 8, this moment, diesel engine was in the rated speed state.After triggering controllable silicon 4, the motor reversing turns down throttle, and when limiting stopper 14 and cut-out electric motor loop when relative near switch 10, diesel engine is in idling mode at this moment.It is to utilize its self-locking property to prevent that gear 21 is rotated further because of inertia that reducing gear 70 adopts worm drive.
This programme can be by wireless or wired input instruction, with the Wireless remote control machine or directly with automatically controlled knob command signal is imported control loop.Be specially adapted to the remote operation throttle for IC engine and open greatly, turn down and shut down, can make things convenient for, control in time the working state of motor.Control circuit has the sequence control function, and shutdown can only be carried out after motor is in idling mode.Motor gets rid of load back and shuts down, and unlikely machine is caused damage.
