Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, the address that the front end of camshaft is well known to those skilled in the art, exactly, one end camshaft being provided with timing gear or timing belt pulley is front end, and the other end relative with front end is rear end.
As shown in Figure 1, the utility model provides a kind of cam assembly, and this cam assembly comprises camshaft body 10, and this camshaft body 10 is provided with functional part 20.
This camshaft body 10 can be monolithic construction, that is, cam shaft blank machining can be gone out multiple for driving the cam of the opening and closing of intake valve and exhaust valve.
Functional part 20 can be the parts realizing camshaft additional function of any appropriate, and such as, as shown in Figure 3, can be oil pump driving cam 21 and phase place inductance loop 22, the utility model limit this.
Therefore by adopting split-type design, camshaft body 10 is installed the functional part 20 of needs, and therefore camshaft body 10 and functional part 20 can adopt different material manufactures, meet the different demands of various functional part 20, and simplified processing process, improving production efficiency.
Preferably, for driving oil pump, as shown in Figure 4, this functional part 20 can be oil pump driving cam 21, therefore oil pump can be driven to rotate to promote plunger reciprocates by oil pump driving cam 21, thus drive operation of oil pump, so that burning will be participated in fuel oil spirt firing chamber to drive motor.
For the benefit of space is arranged, as shown in Figure 4, this oil pump driving cam 21 is arranged on the rear end of this camshaft body 10, namely, with camshaft body 10, contrary one end of timing gear or timing belt pulley is installed, thus can avoids and produce Steric clashes between timing gear or timing belt pulley.
For gathering rotation angle and the tach signal of camshaft body 10, as shown in Figure 3, described functional part 20 is phase place inductance loop 22, therefore can be matched by phase place inductance loop 22 and CMPS Camshaft Position Sensor, the rotation angle of the camshaft body 10 gathered and tach signal are inputted electronic control unit, to determine time of ignition and oil injection time.
Similarly, for the benefit of space is arranged, as shown in Figure 3, this phase place inductance loop 22 is arranged on the rear end of this camshaft body 10, and principle is identical with above-mentioned oil pump driving cam 21 mounting point, does not repeat at this.
Preferably, for realizing driving oil pump motion simultaneously, and can gather the rotational parameters of camshaft body 10, described functional part 20 is oil pump driving cam 21 and phase place inductance loop 22.
Further, for the benefit of space is arranged, as shown in Figure 1, described oil pump driving cam 21 and described phase place inductance loop 22 are all installed to the rear end of this camshaft body 10, and this oil pump driving cam 21 is positioned at the inner side of this phase place inductance loop 22.Due to camshaft body 10 axle journal from the inside to the outside diameter reduce gradually, therefore oil pump driving cam 21 is arranged on the inner side of phase place inductance loop 22, the frictional force of axle journal and oil pump driving cam 21 can be increased, be more conducive to drive oil pump.
It should be noted that herein, refer to that deep is outward, and particularly, is inner side in the middle part of camshaft body 10, and towards camshaft body 10 end is outside in axial centre is relative to " interior " and " outward " of this type of axle class.
Existing cam assembly cannot adapt to the demand of versatility, a kind of cam assembly can only adapt to a kind of engine model, for the platform of planning many moneys motor, if adopt existing design, even if local some variation also there will be multiple camshaft, increase production management cost, reduce manufacturing efficiency.
And in this preferred implementation, a kind of camshaft body 10 goes for the cam assembly of additional function not of the same race, that is, when needs drive oil pump, only on camshaft body 10, install oil pump driving cam 21, uneasiness is pretended an inductance loop 22; When needing the rotational parameters gathering camshaft body 10, only on camshaft body 10, install phase place inductance loop 22, and uneasy oil loading pump driving cam 21.
Namely, by leaving the mounting point of additional functional part 20 on camshaft body 10, such as oil pump driving cam 21 and phase place inductance loop 22, can optionally install according to demand, therefore, it is possible to meet Car design hardware and software platform and modular requirement, reduce and design and develop cost, Parts Purchasing cost, production management cost, the design and development that can realize more product type with lower design cost is produced.
In addition, the utility model also provides a kind of motor, and this motor comprises above-mentioned cam assembly.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
