Summary of the invention
The utility model mainly is that the signal panel phase place that solves the prior art existence is transmitted technical problems such as inaccurate, and a kind of direct reading type signal panel that can accurately judge phase place are provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of direct reading type signal panel are provided, these signal panel are one and adopt the rammed disk of steel plate, be installed on the camshaft, its periphery particularly in these signal panel is provided with several signal teeth that varies in size and grooves, described signal teeth and groove are mutual dissymmetrical structure, the bottom of groove and be located between the through hole of disc centre and form annular matrix, side of this annular matrix extends to the outer rim of signal teeth.Asymmetric signal teeth and groove can provide digital voltage signal to engine control module in the process that signal panel rotate a circle, and determine the firing order of motor with this.
As preferably, described signal teeth comprises two large-signal teeth and two small-signal teeth, wherein be processed as little groove between two large-signal teeth, be processed as big groove between two small-signal teeth, be processed as big groove and little groove between small-signal tooth and the large-signal tooth respectively.This kind arrangement mode not only can transmit turn signal exactly and produce also more convenient.
As preferably, the tooth in the described large-signal tooth prolongs corresponding with the compression top center of first cylinder.It is unique rotating the side tooth edge of having only this large-signal tooth in the week at signal panel, thereby can not produce the possibility of transmitting error signal.
As preferably, the plane at the place, edge of described signal teeth is by the core of signal panel.This kind design can make the signal panel structure more reasonable, firmer, convenient for production.
As preferably, the formed circle of the outer rim of described signal teeth and the concyclic heart of annular matrix, and the ratio of the radius of described through hole and the radius of signal panel is 1: 1.8-1: 2.2.Described large-signal tooth is 1 with the ratio of the radian of big groove: 0.9-1: 1.1; The small-signal tooth is 1 with the ratio of the radian of little groove: 0.9-1: 1.1.The width of described annular matrix is 1 with the ratio of the height of signal teeth: 2.1-1: 2.5.These some suitable sizes can be strengthened the soundness of signal panel.
As preferably, the extending body of a side of described annular matrix connects in little groove processing and is breach.
As preferably, described annular matrix inner side surface is provided with a rectangular recess.This little rectangular recess can make things convenient for signal panel to be installed on the rotatingshaft.
As preferably, described direct reading type signal panel are connected with sensor, and sensor sends digital voltage signal to engine control module, thereby determine the firing order of motor.Petrol engine carries out the IGNITION CONTROL of motor by the acting in conjunction of signal panel, sensor, engine control module.
Therefore, the utlity model has rational in infrastructurely, cost is low, characteristics such as convenient for production, the firing order that a kind of asymmetric signal teeth can the effective recognition difference cylinder especially is provided, transmits camshaft phase information exactly, improve the stationarity of engine running.
