Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
As accompanying drawing 1,2, shown in 3, the utility model is a kind of novel engine valve lift operating mechanism, comprise valve spring 6, valve 7, described novel engine valve lift operating mechanism also comprises control motor 1, shift fork 2, roller sliding sleeve 3, roller 4, valve roller back shaft 5, sleeve track groove 8, described control motor 1 is connected with shift fork 2, sets out the sleeve track groove 8 of long groove shape on the roller sliding sleeve 3 of hollow, and valve roller back shaft 5 two ends are provided with roller 4, roller 4 is installed in the sleeve track groove 8, described shift fork 2 ends are provided with draw-in groove structure 9, and draw-in groove structure 9 contacts with valve roller back shaft 5, and described valve roller back shaft 5 is connected with valve 7, pocketed springs 6 on the valve 7, and described stepper motor is connected with Engine ECU.
Described control motor 1 is connected with the shift fork 2 of " Y " shape structure, one end of the band draw-in groove structure 9 of shift fork 2 is arranged in the roller sliding sleeve 3 of cylinder-like structure, shift fork 2 the other ends extend roller sliding sleeve 3 outsides, be connected with control motor 1, the roller 4 at described valve roller back shaft 5 two ends is arranged on can be along the free movable structure of the structure of sleeve track groove 8, and the sleeve track groove 8 of described trough type is set to the structure with 10 one-tenth angles of roller sliding sleeve end face of roller sliding sleeve 3.
