Below with reference to Fig. 1-Fig. 3, the thrust structure 4 for engine cam 1 according to the embodiment of the present invention is described, thrust structure 4 can prevent camshaft 1 along its axial motion, thus make the cooperation between cam and valve more stable, and then achieve the normal operation of motor.
As shown in Figure 1, the thrust structure 4 for engine cam 1 of embodiment according to a first aspect of the present invention, motor comprises cylinder cap 2 and is located at the valve chamber cover 3 at cylinder cap 2 top, and camshaft 1 is between cylinder cap 2 and valve chamber cover 3.Such as in the example of fig. 1, cylinder cap 2 and valve chamber cover 3 limit holding space jointly, and camshaft 1 can flatly be arranged in holding space.
Thrust structure 4 is located between cylinder cap 2 and valve chamber cover 3, and thrust structure 4 coordinates with one of them in cylinder cap 2 and valve chamber cover 3 axial motion along camshaft 1 preventing camshaft 1 by locating stud 5.That is, thrust structure 4 can be coordinated with cylinder cap 2 by locating stud 5, or thrust structure 4 is coordinated with valve chamber cover 3 by locating stud 5.When thrust structure 4 and cylinder cap 2 join and time, camshaft 1 is between thrust structure 4 and cylinder cap 2, and when thrust structure 4 coordinates with valve chamber cover 3, camshaft 1 is between valve chamber cover 3 and thrust structure 4.Alternatively, locating stud 5 is straight pin.
Such as in one of them example of the present invention, camshaft 1 is provided with two extension parts, two extension parts being axially spaced apart from each other at camshaft 1, alternatively, each extension part is from periphery wall the extending radially outwardly along camshaft 1 of camshaft 1, the distance that two extension parts are spaced apart from each other can equal the thickness of thrust structure 4, during assembling, thrust structure 4 is arranged between two extension parts, in the working procedure of motor, because thrust structure 4 is fixedly connected on cylinder cap 2 or valve chamber cover 3 by locating stud 5, and by only using instead between two sides of thrust structure 4 and two extension parts, now two sides of thrust structure 4 are thrust surface, the surface engagement that two thrust surfaces are relative with two extension parts respectively, thus effectively prevent the axial motion of camshaft 1 along camshaft 1.Thus, by arranging independent component and thrust structure 4, thrust structure 4 is more easily processed, and the distance between two thrust surfaces also can be more accurate, and thrust gap also more easily ensures, thus prevents camshaft 1 along its axial motion better.
By adopting locating stud 5 such as straight pin, thrust structure 4 is arranged on cylinder cap 2 or valve chamber cover 3, not only can securely thrust structure 4 be fixedly connected on cylinder cap 2 or valve chamber cover 3, and the accurate location that can realize between thrust structure 4 and cylinder cap 2 or valve chamber cover 3, avoid cooperation place and occur distortion, thus extend the working life of thrust structure 4, cylinder cap 2 or valve chamber cover 3.
Due to the overall compact assembling structure of thrust structure 4 and cylinder cap 2 or valve chamber cover 3, thus thrust structure 4 can be arranged on the arbitrary position along its axis of camshaft 1, and arrangement is more flexible.
According to the thrust structure 4 for engine cam 1 of the embodiment of the present invention, thrust structure 4 is arranged on cylinder cap 2 or valve chamber cover 3 by locating stud 5, effectively ensure that the assembly precision of thrust structure 4 and cylinder cap 2 or valve chamber cover 3, and make overall engine compact structure, save space, flexible arrangement and reduce cost.
