Abstract
The utility model provides an air valve tappet for an automobile engine, belongs to the field of automobile engines, and solves the problem that the lubrication between the conventional air valve tappet and a guide pipe wall is insufficient. The air valve tappet with an improved structure comprises a tappet body, wherein an oil storage trough and a plurality of oil guide grooves are formed in the arc side surface of the tappet body, and are distributed in the circumferential direction of the tappet; one end of each oil guide groove is communicated with the oil storage trough; and the other end of the oil guide groove extends to penetrate the top surface in the axial direction. As the oil storage trough is distributed in the circumferential direction of the tappet, the lubricant in the oil storage trough uniformly flows to the surface, which is in contact with the guide pipe wall, of the cylinder head during the movement of the air valve tappet, and the lubrication between the air valve tappet and the guide pipe wall is sufficient; and due to the arrangement of the oil storage trough and the oil guide grooves, the contact area between the air valve tappet and the guide pipe wall is reduced, the abrasion on the air valve tappet is reduced, and the service life of the air valve tappet is prolonged. Moreover, the air valve tappet has the advantages that the structure is simple and the working reliability is high.
Description
Technical field
The utility model belongs to the motor car engine field, relates to a kind of automotive engine valves tappet.
Background technique
In overhead camshaft engine, valve tappet is important part in the engine air distribution system, and valve tappet is arranged in the guide of cylinder head.The shape of valve tappet generally has straight cylinder type, waisting shape, T shape etc.The working state that valve tappet is arranged in guide is to move up and down and rotate; Mainly be influenced by the force of sliding friction between tappet and the guide wall during work, its action whether flexibly and area of contact and degree of lubrication between valve tappet and the guide wall very big relation is arranged.
Existing straight cylinder type valve tappet outer surface is generally made the light face, and the end face of valve tappet is provided with cam, and the oil droplets of splashing on the cam drops on the end face of valve tappet.Machine oil is along with the surface of contact that flows to valve tappet and guide wall that moves up and down and rotate of tappet is lubricated.Because it is the valve tappet of straight cylinder type and the area of contact of guide wall are big and lubricant oil gets into the surface of contact difficulty, to such an extent as to lubricated insufficient.
In order to address the above problem, Chinese utility model patent [ZL200820171415.1] discloses a kind of band oil guide slot valve tappet.This valve tappet is straight cylinder type, along the tappet outboard shafts to oil guide slot is set, in oil guide slot, be provided with oil guiding hole and spill port.This device has effectively reduced the area of contact between valve tappet and the guide wall; But because after lubricant oil comes out from oil guiding hole; Moving up and down and rotating along with tappet; Lubricant oil is lubricated along the oil guide slot inflow valve tappet of axial setting and the surface of contact of guide wall, will cause lubricant oil to be difficult for being evenly distributed on the surface of contact like this, thereby makes lubricated insufficient.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, proposed a kind of along with valve tappet with respect to the motion of guide wall, lubricant oil is easy to be evenly distributed on the surface of contact of valve tappet and guide wall, lubricates valve tappet more fully.
The purpose of the utility model can realize through following technical proposal: a kind of automotive engine valves tappet; Comprise columned cylinder; Described cylinder has end face and side, it is characterized in that, offers the oil storage tank that can be communicated with end face on the side of described cylinder.
Lubricant oil is dropped on the end face of valve tappet; Moving up and down and rotating along with tappet; Flow of lubricant in the oil storage tank of flow of lubricant on the valve tappet side, oil storage tank is lubricated on the surface of contact between the guide wall of valve tappet and cylinder head, makes fully lubricated.
In above-mentioned automotive engine valves tappet, described oil storage tank comprises that at least one is opened on the side and along the groove of the extending circumferentially of cylinder.
In above-mentioned automotive engine valves tappet, described groove is a circular groove.The edge of circular groove is the side of valve tappet; Flow of lubricant is in circular groove; Lubricant oil in the circular groove flows in the valve tappet movement process on the surface of contact of guide wall of valve tappet and cylinder head uniformly; Make lubricating fully between valve tappet and cylinder head, reduced the wearing and tearing of valve tappet, prolonged the working life of valve tappet simultaneously.
In above-mentioned automotive engine valves tappet, described oil storage tank comprises some oil guide slot, and described oil guide slot one end is communicated with groove, and the other end runs through end face.
Lubricant oil flow in the oil guide slot from the end face of valve tappet; Flow in the annular groove again; Be stored in that oil in the groove flows to the edge of groove and the motion through valve tappet is evenly distributed between valve tappet and the guide wall, carry out lubricious its surface of contact.
In above-mentioned automotive engine valves tappet, described oil guide slot axially is opened on the side along cylinder.
At above-mentioned automotive engine valves tappet, offer 2~8 oil guide slot on the described side.
Compared with prior art, this automotive engine valves tappet has the following advantages:
1, on the side, is provided with the groove of annular; Flow of lubricant is in circular groove; Lubricant oil in the circular groove flows in the valve tappet movement process on the surface of contact of guide wall of valve tappet and cylinder head uniformly; Make lubricating fully between valve tappet and guide wall, reduced the wearing and tearing of valve tappet, prolonged the working life of valve tappet.
2, be provided with vertically the some oil guide slot that distribute in the side, an end of oil guide slot is communicated with groove, and the other end runs through end face, facilitates like this by cam and splashes in flow of lubricant on the valve tappet end face in groove, has increased the efficient of lubricating.
3, this automotive engine valves tappet is provided with some oil guide slot of circumferential grooves distributed and axial distribution in the side; So just reduce the area of contact between the guide wall of valve tappet and cylinder head, reduced the friction between the guide wall of valve tappet and cylinder head.
