Abstract
The utility model provides a camshaft signal disk structure and an engine, and solves the problems that the arrangement positions of a camshaft signal disk and a camshaft position sensor are limited because the space between the tail end of a camshaft and a cylinder cover is too small due to the limitation of the size of the overall engine and the mounting position of the camshaft. The camshaft signal disk structure comprises a VVT (variable valve timing) phaser assembly and a camshaft connected with the VVT phaserassembly, and furthercomprises a camshaft signal disk which is connected with one end, far away from the camshaft, of the VVT phaser assembly through a bolt structure. According to the engine disclosed by the utility model, the camshaft signal disk is fixed to the outer end surface of the VVT phaserassembly, so that the problem that the camshaft signal disk and the camshaft position sensor are arrangeddifficulty because of small space is solved; the reliabilityand the economic efficiencyof the engine are improved on the premise of accurately generating and picking a camshaft position signal of the engine.
Description
Technical field
The utility model relates to engine design technical field, particularly relates to a kind of camshaft signal disk structure and motor.
Background technique
Modern Engine, because Economy and the requirement of discharge environmental protection extensively adopt computer (ECU) and electronic fuel injection system to control, optimize the operating conditions of motor, needs the running state of Obtaining Accurate camshaft thus according to the working principle of motor.The current way of Modern Engine is: at engine cam end axial plane, press-fit the signal panel that rotate with camshaft, and on cylinder cap, arrange CMPS Camshaft Position Sensor.Because the restriction of motor complete machine size and camshaft mounting point causes between tail end of camshaft and cylinder cap space too small, the selection of sensor position suffers restraints, and available engine camshaft signal disk and CMPS Camshaft Position Sensor device are comparatively accurate, complicated, all higher to machining and assembling and setting technological requirement, the possibility breaking down in the cost of production rising bringing and actual using process increases, and assembles simultaneously and keep in repair also inconvenient.
Model utility content
The purpose of this utility model is to provide a kind of camshaft signal disk structure and motor, in order to solve available engine, causes the problem of camshaft signal disk and CMPS Camshaft Position Sensor difficult arrangement because of narrow space.
To achieve these goals, the utility model provides a kind of camshaft signal disk structure, comprise: Variable Valve Time VVT phase discriminator assembly and the camshaft being connected with described VVT phase discriminator assembly, also comprise: the camshaft signal disk being connected away from one end of described camshaft by bolt arrangement and described VVT phase discriminator assembly.
Wherein, described camshaft signal disk is by sheetmetal impact briquetting.
Wherein, the bolt aperture of described camshaft signal disk is identical with the bolt aperture of described VVT phase discriminator assembly.
Embodiment of the present utility model also provides a kind of motor, comprises camshaft signal disk structure as above.
The utility model embodiment has following beneficial effect:
The utility model embodiment's camshaft signal disk structure, camshaft signal disk and VVT phase discriminator assembly are passed through to VVT tightening the screw location, fastening away from one end of camshaft, there is very high positioning precision, solve available engine and caused the problem of camshaft signal disk and CMPS Camshaft Position Sensor difficult arrangement because of narrow space, guaranteeing under the prerequisite that engine cam shaft position signal is accurately produced and picks up, overcome assembling and setting technological requirement and the higher shortcoming of cost, improved reliability and the Economy of motor.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, below in conjunction with specific embodiment and accompanying drawing, be described in detail.
The utility model embodiment solves available engine and causes the problem of camshaft signal disk and CMPS Camshaft Position Sensor difficult arrangement because of narrow space, the utility model embodiment provides a kind of camshaft signal disk structure, as depicted in figs. 1 and 2, comprise: Variable Valve Time VVT phase discriminator assembly 3 and the camshaft 4 being connected with described VVT phase discriminator assembly 3, also comprise: the camshaft signal disk 2 being connected away from one end of described camshaft 4 with described VVT phase discriminator assembly 3 by bolt arrangement 1.
The utility model embodiment's camshaft signal disk structure, as shown in Figure 3, camshaft signal disk 2 is installed on to VVT phase discriminator assembly 3 one end away from described camshaft 4 by bolt arrangement 1, make camshaft 4 front ends abundant to the space between front end cover cap, camshaft-signal sensor position choice increases greatly, simplify the structure of corresponding valve mechanism cover and cylinder head simultaneously, reduced the weight of separate unit motor, reduced the cost of motor simultaneously.
In the utility model embodiment, described camshaft signal disk 2 is by sheetmetal impact briquetting, and further, the bolt aperture of described camshaft signal disk 2 is identical with the bolt aperture of described VVT phase discriminator assembly 3.
The utility model embodiment's camshaft signal disk structure, camshaft signal disk bolt aperture equals VVT phase discriminator assembly bolt aperture, then by bolt arrangement 1, is fixed, is located, and has very high positioning precision, concrete, described bolt arrangement can tight a bolt for VVT.
The utility model embodiment's camshaft signal disk structure, adopt sheetmetal impact briquetting, accurate positioning hole and VVT phase discriminator assembly 3 and camshaft 4 are set accurately locate, guaranteeing under the prerequisite that engine cam shaft position signal is accurately produced and picked up, overcome assembling and setting technological requirement and the higher shortcoming of cost, improved reliability and the Economy of motor.
The corresponding camshaft signal disk structure due to the utility model embodiment, be applied to motor, therefore, the utility model embodiment also provides a kind of motor, wherein, described in above-mentioned camshaft signal disk structure, realize in the embodiment that embodiment is all applicable to this motor, also can reach identical technique effect.
The utility model embodiment's camshaft signal disk structure and motor, solved the problem that causes camshaft signal disk, CMPS Camshaft Position Sensor difficult arrangement because of narrow space, and the utility model embodiment have lightweight, processing cost is low, assemble simple advantage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
