Abstract
The utility model belongs to the technical field of automobile part tools, particularly relates to an air door rocker arm shaft, and discloses the air door rocker arm shaft. The air door rocker arm shaft comprises a fixing plate and a shaft lever, wherein the fixing plate is vertical to the shaft lever, the obverse side of the fixing plate is in rectangle shape, arc transition is formed at four corners of the rectangle shape, arc transition is formed between a circular groove and the outer wall of the shaft lever, the circular groove is clamped in an axle hole, an air inflow rocker arm groove is formed between the circular groove and an end face of the shaft lever, arc transition is formed between the air inflow rocker arm groove and the outer wall of the shaft lever, an exhausting rocker arm groove is located between the circular groove and the other end face of the shaft lever, and arc transition is formed between the exhausting rocker arm groove and the outer wall of the shaft lever. The air door rocker arm shaft has the advantages that structure is simple, stress applied to the air door rocker arm shaft can be reduced well, use intensity can be greatly improved, and use life is prolonged.
Description
Technical field
The utility model belongs to auto parts apparatus technical field, relates in particular to a kind of valve lever pin.
Background technique
Valve lever pin is the part belonging in auto parts and components, is mainly used for supporting rocking arm and uses.Rocking arm is the convenient size that regulates valve to open under the effect of valve lever pin.Material nonhomogeneous hardness between rocking arm and valve lever pin is larger, long-time rubbing contact, and poor in road conditions especially and Ackermann steer angle rocker torsion kinetic friction valve lever pin, causes valve lever pin inordinate wear for a long time.The unreasonable design of valve lever pin also can make valve lever pin stressed unreasonable, and valve lever pin occurs crackle from stress raiser, and prolonged exercise can rupture.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of valve lever pin is provided, and its technological scheme is as follows:
A valve lever pin, is characterized in that, described valve lever pin comprises fixed plate and axostylus axostyle, and described fixed plate and axostylus axostyle are perpendicular; Fixed plate front is the rectangle of foursquare arc transition, on described fixed plate, offer low groove, low groove parallels with the long limit of fixed plate, arc transition between described low groove and fixed plate, the place, two ends of described low groove is provided with cylindrical hole, the circular arc concentric of cylindrical hole and fixed plate corner location, the middle of the long side face on the long limit of fixed plate offers axis hole; Described axostylus axostyle is cylindrical body, the outer wall middle of axostylus axostyle offers circular groove, arc transition between circular groove and the outer wall of axostylus axostyle, and circular groove is arranged in axis hole, between end face of described circular groove and axostylus axostyle, be provided with intake rocker groove, arc transition between intake rocker groove and the outer wall of axostylus axostyle; Between described circular groove and axostylus axostyle other end, be provided with exhaust rocker arm groove, arc transition between exhaust rocker arm groove and the outer wall of axostylus axostyle.
The valve lever pin that the utility model provides, when in use, cylindrical hole and miscellaneous part that place, the two ends of low groove is provided with fix, thereby make whole valve rocker more stable.Intake rocker groove is to be connected with intake rocker, plays the effect of air inlet.Exhaust rocker arm groove is to be connected with exhaust rocker arm, plays the effect of exhaust.
The beneficial effects of the utility model are:
The utility model is simple in structure, can be good at reducing the stress that valve lever pin is subject to, and can strengthen greatly working strength, increases working life.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A valve lever pin, is characterized in that, described valve lever pin comprises fixed plate 1 and axostylus axostyle 2, and described fixed plate 1 and axostylus axostyle 2 are perpendicular; Fixed plate 1 front is the rectangle of foursquare arc transition, on described fixed plate 1, offer low groove 3, low groove 3 parallels with the long limit of fixed plate 1, arc transition between described low groove 3 and fixed plate 1, the place, two ends of described low groove 3 is provided with cylindrical hole 4, the circular arc concentric of cylindrical hole 4 and fixed plate 1 corner location, the middle of the long side face on the long limit of fixed plate 1 offers axis hole 5; Described axostylus axostyle 2 is cylindrical body, the outer wall middle of axostylus axostyle 2 offers circular groove 6, arc transition between the outer wall of circular groove 6 and axostylus axostyle 2, circular groove 6 is arranged in axis hole 5, between 2 one end faces of described circular groove 6 and axostylus axostyle, be provided with intake rocker groove 7, arc transition between intake rocker groove 7 and the outer wall of axostylus axostyle 2; Between described circular groove 6 and axostylus axostyle 2 other ends, be provided with exhaust rocker arm groove 8, arc transition between exhaust rocker arm groove 8 and the outer wall of axostylus axostyle 2.
The valve lever pin that the utility model provides, when in use, cylindrical hole and miscellaneous part that place, the two ends of low groove is provided with fix, thereby make whole valve rocker more stable.Intake rocker groove is to be connected with intake rocker, plays the effect of air inlet.Exhaust rocker arm groove is to be connected with exhaust rocker arm, plays the effect of exhaust.
