In above-mentioned engine gudgeon pin, the both ends of the surface of described rubber blanket all offer in the form of a ring and for storing the oil storage tank of lubricating oil, described oil storage tank is coaxial with rubber blanket.
Use above-mentioned structure, both rubber blanket can have been made the most readily to deform upon, the friction between rubber blanket and connecting portion and pressure ring can be reduced again, thus extend the time that rubber blanket contacts with connecting portion and pressure ring, improve the structural stability of this piston pin further.
In above-mentioned engine gudgeon pin, the two ends in described conquassation hole connect with two oil storage tanks respectively.
Use above-mentioned structure, enable rubber blanket to store more lubricating oil, extend the life-span of rubber blanket further, so that the purpose improving this piston pin structural stability stably realizes.
Compared with prior art, this engine gudgeon pin has the advantage that
1, the conical surface one and the conical surface two closely against, make between press section and body, to produce bigger friction, and under the effect of this friction, make press section and body form an entirety, thus be effectively improved the connective stability of pressure ring and body.
, by arranging rubber blanket between pressure ring and body and bolt shank is wrapped in rubber blanket, and rubber blanket can absorb, by the elastic deformation of self, the vibrations produced when sleeve occurs to rub, thus be prevented effectively from these vibrations and be transferred on bolt, bolt is made to be in locking state all the time, thus improve pressure ring and the stability of body connection further, to improve the structural stability of this piston pin.
, by offering the oil storage tank for storing lubricating oil in the both ends of the surface of rubber blanket, both rubber blanket can have been made the most readily to deform upon, the friction between rubber blanket and connecting portion and pressure ring can be reduced again, thus extend the time that rubber blanket contacts with connecting portion and pressure ring, improve the structural stability of this piston pin further.
