Description
Technical field
The utility model relates to a kind of energy conservation of motor, is related specifically to a kind of engine valve actuating mechanism ball tappet.
Background technique
Along with the development of modern economy society, thousands upon thousands family come into by automobile.National legislation requires also improving constantly to various types of vehicles fuel consume and emission limit, reduce motor fuel consume and improve the key technology task that emission performance has become Engine Industry.In order to the fuel consume reducing motor can improve from many aspects, the friction consumption wherein reducing engine pack is also a wherein important ring.Friction this consumption ratio between engines distribution cam and tappet is higher, and be sliding friction between common tappet and cam, also larger to the wearing and tearing of cam and tappet during engine operation, therefore design a kind of novel tappet, realize being rolling friction between valve cam and tappet, significant.
Summary of the invention
For solving the problem of sliding friction between prior art engines distribution cam and common tappet, the utility model proposes a kind of engine valve actuating mechanism ball tappet.
The purpose of this utility model is achieved through the following technical solutions:
Feature of the present utility model is: comprise the large end of tappet, tappet small end, locating stud, ball, special bolts, jump ring; The large end head of described tappet is provided with special hole; The special nose end of the large end head of described tappet is provided with tapped hole, and tapped hole end is provided with restraining groove; The large end afterbody of described tappet is provided with tapped hole, is radially provided with positioning hole; Described tappet small end is linked together by screw thread and pin and the large end of tappet; There is screw thread described tappet small end one end; On described tappet small end, thread section is provided with positioning hole; Described locating stud is located in the positioning hole of tappet large end afterbody positioning hole and tappet small end; Described ball is arranged in the special hole of the large end head of tappet; Described special bolts is arranged in the tapped hole of the large end head of tappet; Described jump ring is located in the restraining groove of the large end of tappet.
Above-mentioned special bolts head is provided with opening groove, is convenient to installing/dismounting; Described special bolts is provided with oil duct vertically.
Above-mentioned tappet small end is provided with oil duct vertically.
Above-mentioned locating stud is located in the positioning hole of the large end afterbody of tappet and tappet small end threaded end by interference fit.
The Advantageous Effects of the utility model engine valve actuating mechanism ball tappet on cam contact surface, realizes rolling friction by the ball of ball tappet.Further, structure is simple, assemble, safeguard simple and reliable, practical.
