Abstract
The invention discloses a signal collecting system of a diesel engine camshaft. The signal collecting system of the diesel engine camshaft comprises a camshaft timing gear, signal pins or signal holes, and a camshaft signal transducer. The camshaft timing gear is arranged on the camshaft, the signal pins or the signal holes are arranged at the axial outer end of the camshaft timing gear, and the camshaft signal transducer is axially arranged on the outer side of the camshaft timing gear and is used for collecting the signals of the signal pins or the signal holes which rotate along with the camshaft timing gear. The signal collecting system of the diesel engine camshaft is reasonable in structure, the signal pins or the signal holes which are arranged on the camshaft timing gear replace an original camshaft signal panel to be used as signal sources which are collected through the camshaft signal transducer, and thus the structure of the system is simplified. In addition, due to the fact that the camshaft signal transducer is axially arranged on the outer side of the camshaft timing gear, the influence of gear teeth of the camshaft timing gear on the collected signals is avoided, and collecting precision is improved.

The present invention is in order to overcome defect in above-mentioned prior art, provides a kind of simple and reasonable, and assembling difficulty is low, the cam shaft for diesel engine signal acquiring system that the signals collecting precision is high.
, for achieving the above object,, according to the invention provides a kind of cam shaft for diesel engine signal acquiring system, comprising:
Camshaft timing gear, cloth are contained on camshaft;
Signal pin or telltale hole, be laid in the axial outer end of camshaft timing gear;
The camshaft signal sensor, axially be laid in the outside of camshaft timing gear, is used for gathering the signal pin of following the camshaft timing gear rotation or the signal of telltale hole.
In technique scheme, signal pin is fitted on described camshaft timing gear by temperature differential method.
In technique scheme, signal pin is round pin or square cotter.
In technique scheme, when signal pin was round pin, its insertion end had the taper guide portion; When signal pin was square cotter, it comprised: cylinder inserting paragraph and square signal segment, the end of cylinder inserting paragraph has the taper guide portion.
In technique scheme, telltale hole is circular hole or square hole.
In technique scheme, signal pin or telltale hole are laid on the inner circumference of axial outer end face of camshaft timing gear according to the interval that needs of camshaft signal sensor collection signal.
Compared with prior art, the present invention has following beneficial effect: this cam shaft for diesel engine signal acquiring system is rational in infrastructure, by being laid in signal pin or the telltale hole on camshaft timing gear, use and replace original camshaft signal disk as the signal source that the camshaft signal sensor gathers, simplified system architecture; In addition, camshaft signal sensor cloth axially is laid in the outside of camshaft timing gear, has avoided the impact of the gear teeth of camshaft timing gear on collection signal, has improved acquisition precision.

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 mode of execution of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technological scheme of the present invention.
Cam shaft for diesel engine signal acquiring system of the present invention is rational in infrastructure, by being laid in signal pin or the telltale hole on camshaft timing gear, using, replaces original camshaft signal disk as the signal source that the camshaft signal sensor gathers, and has simplified system architecture; In addition, camshaft signal sensor cloth axially is laid in the outside of camshaft timing gear, has avoided the impact of the gear teeth of camshaft timing gear on collection signal, has improved acquisition precision.
Embodiment one:
As shown in Figures 2 and 3, the concrete structure of this cam shaft for diesel engine signal acquiring system comprises: camshaft timing gear 21, signal pin 22 and camshaft signal sensor, camshaft timing gear 21 cloth are contained on camshaft, signal pin 22 is fitted in the axial outer end of camshaft timing gear 21 by temperature differential method, can be laid on the inner circumference of axial outer end face of camshaft timing gear 21 according to the interval that needs of camshaft signal sensor collection signal, both belong to the whole supply of material camshaft timing gear 21 and signal pin 22.When camshaft arranges, only camshaft timing gear 21 need to be contained on camshaft and get final product, reduce the difficult problem of assembling.
As shown in Figure 4 and Figure 5, signal pin 22 is round pin or square cotter; When signal pin 22 was round pin, its insertion end had the taper guide portion; When signal pin 22 was square cotter, it comprised: cylinder inserting paragraph and square signal segment, the end of cylinder inserting paragraph has the taper guide portion.Signal pin 22 has versatility, can reduce the design of dedicated cam axis signal dish according to need to being used by other timing gear assemblies of camshaft signal sensor collection signal, has reduced design difficulty.
The camshaft signal sensor adopts the outside that axially is laid in camshaft timing gear 21, is used for gathering the signal of the signal pin 22 of following camshaft timing gear 21 rotations.Because camshaft timing gear 21 is positioned at camshaft timing gear 21 radially, its gear teeth are less on the impact of camshaft signal sensor collection signal, can improve the signals collecting precision of camshaft signal sensor.
