The utility model has the benefits that the signal feedback device has high precision and reliability, the accuracy for the sensor to collect the signal is improved, and the cost is reduced.
Description
Technical field
The utility model relates to DENG suction and discharge and oil spout control gear, is specifically related to a kind of novel camshaft gear wheel, carries out the oil spout of feedback control fuel pump by camshaft control intake and exhaust signal through the gear face gusset.
Background technique
Present most of DENG is to sell through on the camshaft gear wheel disc, by specific angle in correct time induction being installed, and four cylinder engine is installed five induction pins usually, seven induction pins of six cylinder engine installation; Induction pin through the sensor sensing signal, sends signal to ECU along with the camshaft gear wheel rotation, and ECU is through the opportunity of identification signal control Injection Pump to the in-cylinder injection fuel oil.This structure is the hole that on the camshaft gear wheel disc, drills and reams, and is transferred on the camshaft gear wheel with manufactured straight pin interference again, increased the positional error of pin after its assembling, causes sensor readings not accurate enough, influences the opportunity of fuel injection in the cylinder; The operation of extra increase has also increased the manufacture cost of camshaft gear wheel.
Summary of the invention
The utility model provides a kind of novel camshaft gear wheel, effectively solves the above-mentioned technical problem that existing signal panel package assembly exists.
Take following technological scheme for realizing above-mentioned functions the utility model: DENG new type of cam shaftgear is made up of magnetometric sensor (1), ECU (2), Injection Pump (3), cylinder (4) and camshaft gear wheel (5); On the camshaft gear wheel disc (6) of camshaft gear wheel (5), has similar gusset (7) signal feedback device; Signal feedback device has the signal pin (10) that directly forges by specific angle; Said DENG is four cylinders, has five signal pins (10) on its camshaft gear wheel disc (6); The angle of the timing marks tooth (8) of said signal pin (10) and camshaft gear wheel (5) along arranged clockwise is: 86 ° 29 ' 24 ", 176 ° 29 ' 24 ", 251 ° 29 ' 24 ", 266 ° 29 ' 24 ", 256 ° 29 ' 24 "; Said signal pin (10) position error can be controlled in the 0.4mm; It is 15 degree～60 degree that said similar gusset (7) has the tilt angle with camshaft gear wheel disc (6), and the tilt angle best angle is 45 °.
The utility model is helpful to be: improved the precision and the reliability of signal feedback device, improved the degree of accuracy of sensor pickoff signals; Omit operations such as boring, fraising, dress pin; Reduced the manufacture cost of camshaft gear wheel.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 2 is signal panel card figure.
Illustration: magnetometric sensor 1, ECU 2, Injection Pump 3, cylinder 4, camshaft gear wheel 5, camshaft gear wheel disc 6, similar gusset 7, timing marks tooth 8, telltale hole 9, signal pin 10.
Embodiment
As shown in Figure 1, DENG new type of cam shaftgear is made up of magnetometric sensor 1, ECU 2, Injection Pump 3, cylinder 4 and camshaft gear wheel 5; On the camshaft gear wheel disc 6 of camshaft gear wheel 5, have similar gusset 7 signal feedback devices; Similar gusset 7 has the tilt angle that 15 degree～60 are spent with camshaft gear wheel disc 6; The tilt angle best angle is elected 45 ° as; Select this angle, engine structure is the compactest, and little, reduction engine weight takes up room.
As shown in Figure 2, signal feedback device has the signal pin 10 that directly forges by specific angle; For four cylinder DENGs; Have five signal pins 10 on its camshaft gear wheel disc 6, along arranged clockwise be with the angle of the timing marks tooth 8 of camshaft gear wheel 5: 86 ° 29 ' 24 ", 176 ° 29 ' 24 ", 251 ° 29 ' 24 ", 266 ° 29 ' 24 ", 356 ° 29 ' 24 "; Signal pin 10 position errors can be controlled in the 0.4mm.
As shown in Figure 1; In engine operation process; When signal plate 6 ran to the induction range of magnetometric sensor 1, magnetic force induction device 1 changes the magnetic force change into signal passed to ECU2, and ECU2 receives the instruction back through calculating, analysis; Injection Pump 3 is passed in instruction, and Injection Pump 3 begins oil spout in cylinder 4 after receiving instruction.
