Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure and be benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technical scheme of the present invention.
Crankshaft rotation speed signal panel of the present invention adopts and is assemblied in the forward type structure on crankshaft vibration damper, and cost is low, long service life; And adopt and on its disk body circumference, lay groove double wedge interphase structure, make its cutting crankshaft rotational speed sensor magnetic line of force, change its magnetic flux, produce the sinusoidal induced voltage be directly proportional with it and export to ECU (Electrical Control Unit) ECU by the coil that is wrapped in sensor internal, to improve the signals collecting reliability.
As shown in Figure 1 to Figure 3, this crankshaft rotation speed signal panel adopts the moulding of thinner thickness steel plate punched, and its concrete structure comprises: disk body 1, and be arranged on tach signal collection section and the location division on this disk body 1.Wherein, disk body 1 assembles and is positioned on crankshaft vibration damper by location division, be rigidly attached to again on bent axle, make " 0 " scale of crankshaft rotation speed signal panel and sensor to timing, bent axle the first cylinder is in the first cylinder top dead centre, then, by cutting crankshaft rotational speed sensor magnetic line of force of the tach signal collection section on it, changes its magnetic flux, produce the sinusoidal induced voltage be directly proportional with it and export to ECU (Electrical Control Unit) ECU by the coil that is wrapped in sensor internal, so that speed of crankshaft is gathered.Disk body 1 adopts the moulding of thinner thickness steel plate punched, and thickness is generally (1.5-3.5) mm, simple in structure, quality is light, is convenient to be assemblied on crankshaft vibration damper, reduces simultaneously the bent axle rotating load, has improved the reliability of speed of crankshaft signals collecting.
Tach signal collection section comprises: be disposed on collection groove 21 and toothless portion) 22 on disk body 1 circumference, and gathering the collection double wedge 23 formed between groove 21.Gather that groove 21 is spaced apart to be located on disk body 1 circumference, between adjacent collection groove 21, separate by gathering double wedge 23, form the interphase structure that gathers groove 21 and gather double wedge 23, when this crankshaft rotation speed signal panel rotates with crankshaft vibration damper, alternate collection groove 21 and the collection double wedge 23 cutting crankshaft rotational speed sensor magnetic lines of force, change its magnetic flux.The variation of magnetic flux, produce the sinusoidal induced voltage be directly proportional with it and export to ECU (Electrical Control Unit) ECU by the coil that is wrapped in sensor internal.The quantity that gathers groove 21 is 58, and each width that gathers groove 21 equates, is generally (5-8) mm, and the included angle B of two adjacent collection grooves 21 or collection double wedge 23 is 6 °.
In addition, the arranged outside that gathers groove 21 and collection double wedge 23 has the rib limit 24 of width (2-4) mm, makes to gather groove 21 and gather double wedge 23 to keep enclosed construction, with the rigidity of raising crankshaft rotation speed signal panel.Certainly, when crankshaft rotation speed signal panel rigidity was enough, rib limit structure can be cancelled, and namely teeth groove is open type.
Toothless portion) 22 is positioned at the collection groove 21 of alternate setting and gathers the bottom right discontinuities of double wedge 23, it is long groove structure or the long toothing (as shown in Figures 2 and 3) that gathers of gathering, the induced voltage of the induced voltage of toothless portion) 22 cutting crankshaft rotational speed sensor magnetic line of force outputs and all the other collection grooves 21 and the 23 cutting crankshaft rotational speed sensor magnetic line of force outputs of collection double wedge is distinguished to some extent, rotates the number of turns for ECU judgement bent axle.ECU, by analyzing induced voltage signal, is translated into the speed of crankshaft signal.
As shown in Figure 4, during the collecting crankshaft tach signal, this crankshaft rotation speed signal panel is assemblied on crankshaft vibration damper, then is rigidly attached on bent axle.By interfix hole 11 and dowel hole 13, determine " 0 " scale position, to timing, bent axle the first cylinder is in the first cylinder top dead centre when " 0 " scale and sensor.Crankshaft rotational speed sensor 3 is arranged on a side of this crankshaft rotation speed signal panel, its signal output part is connected with engine electric-controlled unit ECU4, and the speed of crankshaft signal by crankshaft rotational speed sensor 3 by the crankshaft rotation speed signal panel collection passes to engine electric-controlled unit ECU4.
Wherein on crankshaft rotation speed signal panel, alternate collection groove 21 and collection double wedge 23 cuts the crankshaft rotational speed sensor magnetic lines of force, changes its magnetic flux.The variation of magnetic flux, produce the sinusoidal induced voltage be directly proportional with it and export to ECU (Electrical Control Unit) ECU by the coil that is wrapped in sensor internal.The induced voltage of the induced voltage of the toothless portion) 22 cutting crankshaft rotational speed sensor magnetic line of force outputs on signal panels and all the other collection grooves 21 and the 23 cutting crankshaft rotational speed sensor magnetic line of force outputs of collection double wedge is distinguished to some extent, rotates the number of turns for ECU judgement bent axle.ECU, by analyzing induced voltage signal, is translated into the speed of crankshaft signal.
To sum up, this crankshaft rotation speed signal panel adopts and is assemblied in the forward type structure on crankshaft vibration damper, and cost is low, long service life; And adopt and on its disk body circumference, lay groove double wedge interphase structure, make its cutting crankshaft rotational speed sensor magnetic line of force, change its magnetic flux, produce the sinusoidal induced voltage be directly proportional with it and export to ECU (Electrical Control Unit) ECU by the coil that is wrapped in sensor internal, to improve the signals collecting reliability.
Above disclosed be only several specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
