Abstract
The utility model relates to a reducing-valve distribution cam, comprising a distribution cam body. The reducing-valve distribution cam is characterized in that a pressure-reducing spindle groove and a stress platform are arranged on the distribution cam body, and the pressure-reducing spindle groove is tangent with the end surface of the stress platform. According to the reducing-valve distribution cam disclosed by the utility model, the pressure-reducing spindle groove and the stress platform are arranged on the distribution cam body, and the pressure-reducing spindle groove is tangent with the end surface of the stress platform, thus the structure is simple, the process is easy, the stability of a spindle is improved, and the operation reliability of the pressure-reducing valve is improved.
Description
Technical field
The utility model relates to a kind of valve cam, is specifically related to the valve cam that a kind of motorcycle engine or universal machine motor are used.
Background technique
Along with industry and Agricultural Development; Requirement for the motorcycle transport capacity increases day by day, and big discharge capacity more and more is not used person's favor, but this type motor starts defectives such as difficult, that the electric starting system reliability is low because cylinder presses height to exist pin; To this situation, this mechanism of reduction valve has appearred.Reduction valve mechanism on the Motorcycle Market only is confined to chain making machine at present; Because chain making machine is that overhead cam and cam and cam mandrel are integral type; And being underlying cam and cam, the push rod machine separates manufacturing with the cam mandrel; Can not make one on the push rod machine and be similar to the integral type camshaft of using on the chain making machine, therefore, reduction valve also can not get using on the push rod machine always.
The model utility content
The purpose of the utility model is to provide a kind of reduction valve valve cam that is applicable to the push rod machine.
The purpose of the utility model is to realize like this; A kind of reduction valve valve cam; Comprise the valve cam body, it is characterized in that: said valve cam body is provided with decompression mandrel groove and stressed platform, and the front end of said decompression mandrel groove and the end face of said stressed platform are tangent.
The utlity model has following beneficial effect; The utility model is provided with decompression mandrel groove and stressed platform on the valve cam body; And the front end of decompression mandrel groove and the end face of said stressed platform are tangent, not only simple in structure, easy processing; And improved the stability of mandrel, and then improved the functional reliability of reduction valve.
