The utility model by traditional next door that gear ring is changed to gear ring that is positioned at, and fixes the position of punching press dish with gear ring, and is formed with telltale hole and signal starter hole by punching press on the outer shroud of punching press dish.The punching press dish is sleeved on the bent axle, and starting electrical machinery drives punching press dish and crankshaft rotating by gear ring, makes drive plate realize starting function; Offer telltale hole and signal starter hole on the punching press dish, wherein telltale hole is equal to the tooth root of signal teeth on the classical signal dish, between the two adjacent telltale holes not the part of stamping-out be equal to the tooth top of signal teeth on the classical signal dish, the punching press dish correspondingly has the function of transmitting crankshaft rotation signals like this, when the punching press dish rotates with bent axle, between the telltale hole of punching press dish and the two adjacent telltale holes not the part of the stamping-out signal that passes to crankshaft position sensor be different, the crankshaft position sensor not part of the stamping-out counting that liquidates between the telltale hole of platen and the two adjacent telltale holes, to obtain crankshaft rotation signals, the signal starter hole is used to indicate the initial position of each circle counting.
The utility model is compared with the structure that conventional ADS driving dish and signal panel are installed separately separately, and structure is simpler, compact, and it is more easy to process, and effectively reduces cost of production; The utility model only needs assembling once to get final product on bent axle, has cancelled the operation of other installation signal panel, assembles simplyr, and workman's efficiency of assembling height, labor intensity are little.
The utility model is compared with the structure that conventional ADS driving dish and signal panel are combined, and processing and assembling are easy, and total quality and rotary inertia are little, and not only cost of material is few, and has avoided the oil consumption increase, has ensured the acceleration performance of petrol engine.
For the ease of the accuracy of punch process and the transmission of assurance signal, above-mentioned telltale hole is a square hole, and the signal starter hole is the elongated rectangular shape hole, and the width in this elongated rectangular shape hole equates with the width of square hole.
Beneficial effect: the utility model can be realized transmitting crankshaft rotation signals simultaneously and start function, has simple in structure, easy processing, easy to assembly, characteristics such as cost of production is few, rotary inertia is little, is applicable to all kinds of electronic injection gasoline engines.
