Description
Technical field
The utility model relates to mechanical technique, particularly relates to a kind of camshaft signal acquisition system.
Background technique
In camshaft signal acquisition system, the general signal by camshaft signal sensor collection signal tooth, and the signal of collection is sent to engine electric-controlled unit, to ensure the smooth running of motor.
Fig. 1 is the structural representation of prior art cam axis signal acquisition system.Wherein, signal teeth 12 is fitted in the axial outer end of camshaft timing gear 11, according to camshaft signal sensor collection signal need carry out interval laying.Due to, camshaft signal sensor collection signal is quite strict, and require that the gap between the head of camshaft signal sensor and signal teeth is 1 ± 0.2mm, therefore, camshaft signal sensor must be arranged on engine timing cover.
But, existing camshaft signal acquisition system, on the one hand, in the process of camshaft timing gear work, signal teeth easily gets loose, and makes jitter; On the other hand, because engine timing cover is generally plastic casing, there is no enough intensity and thickness, make motor in running, camshaft signal sensor is often shifted, and causes camshaft signal sensor to be easy to produce and to lose the phenomenon that toe joint can not receive signal.Therefore, the reliability of existing camshaft signal acquisition system is lower.
Model utility content
The utility model provides a kind of camshaft signal acquisition system, in order to improve the reliability of its collection signal.
The utility model provides a kind of camshaft signal acquisition system, comprising: camshaft, camshaft signal sensor, signal teeth and cylinder head, wherein:

Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The sectional drawing of the camshaft signal acquisition system that Fig. 2 provides for the utility model embodiment, Fig. 3 is the structural representation of Fig. 2 convexity wheel shaft, Fig. 4 is the structural representation of Fig. 2 cam axis signal sensor, as shown in figs 2-4, the utility model embodiment provides a kind of camshaft signal acquisition system, comprise camshaft 13, camshaft signal sensor 14, signal teeth 12 and cylinder head 15, wherein, signal teeth 12 is arranged on camshaft 13; Camshaft signal sensor 14 is fixedly connected with cylinder head 15 by linkage structure, and this camshaft signal sensor 14 is oppositely arranged, for the signal of collection signal tooth 12 with signal teeth 12; This cylinder head 15 is located on camshaft 13.
Camshaft signal sensor 14 and signal teeth 12 are oppositely arranged, make the gap between the head of camshaft signal sensor 14 and signal teeth 12 be 1 ± 0.2mm, to improve stability and the acquisition precision of signals collecting.Because cylinder head 15 has very high intensity and thickness, by linkage structure, camshaft signal sensor 14 is fixed in cylinder head 15, camshaft signal sensor 14 can be avoided to be shifted, improve the installation reliability of camshaft signal sensor 14 with this, prevent the jitter owing to gathering or the phenomenon causing engine misses or limp-home such as discontinuous.
The camshaft signal acquisition system that the utility model embodiment provides, camshaft signal sensor is fixedly connected with the cylinder head be located on camshaft by linkage structure, and be oppositely arranged with the signal teeth be arranged on camshaft, effectively prevent getting loose of signal teeth or camshaft signal sensor from the phenomenon of displacement occurring with this, improve the reliability of signals collecting.
In the present embodiment, as shown in Figures 2 and 3, camshaft 13 is one-body molded with signal teeth 12, signal teeth 12 is arranged on the intermediate portion of camshaft 13, adopts identical materials and process to cast, then process.Camshaft 13 and signal teeth 12 are integrated into a part, not only can greatly reduce production process, save installing space, reduce the difficulty and cost of production of assembling, and getting loose of signal teeth can be avoided, ensure that the installation reliability of signal teeth.
In the present embodiment, linkage structure comprises fixing bolt, to make the dismounting between camshaft signal sensor 14 and cylinder head 15 convenient.
In the present embodiment, camshaft signal sensor 14 is Hall transducer, it will be appreciated by those skilled in the art that, camshaft signal inputs in engine electric-controlled unit by camshaft signal sensor 14, to start function smooth running, wherein, camshaft signal can be such as camshaft-position signal.
In the present embodiment, the quantity of signal teeth 12 can be one or more, in the application process of reality, can arrange according to the control planning in engine electric-controlled unit, for the choosing of occurrence of signal teeth quantity, the present embodiment is not particularly limited at this.It will be understood by those skilled in the art that, when camshaft 13 there being multiple signal teeth 12, the placement of multiple signal teeth 12 is relevant with crankshaft signal tooth, and during cam axle, camshaft signal sensor 14 gathers the signal of multiple signal teeth 12 successively.
Last it is noted that above each embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technological scheme.
