Abstract
The utility model belongs to the technical field of automobile part tools, particularly relates to an air door rocker arm, and discloses the air door rocker arm. The air door rocker arm comprises a middle arm body, wherein a boss is arranged on the middle arm body, a rocker arm axle hole is formed in the boss, the rocker arm axle hole transmits to the boss through an arc surface, one end of the middle arm body is connected with an air valve rocker arm, the other end of the middle arm body is connected with a pivot rocker arm, a pivot connecting hole is connected with the end of the pivot rocker arm through an arc concave surface, and an interval between the rocker arm axle hole and the air valve rocker arm is larger than an interval between the pivot rocker arm and the rocker arm axle hole. The air door rocker arm is simple in structure and can reduce stress applied to a plate spring seat well, and use intensity of the air door rocker arm can be greatly improved, and use life of the air door rocker arm is prolonged.
Description
Technical field
The utility model belongs to auto parts apparatus technical field, relates in particular to a kind of valve rocker.
Background technique
Valve rocker is the part belonging in auto parts and components, be mainly used for coordinating camshaft in good time open door, complete air inlet and the exhaust of motor.Material nonhomogeneous hardness between valve rocker and controlling rod, driveshaft is larger, and long-time rubbing contact between valve rocker and controlling rod, driveshaft, causes for a long time valve rocker inordinate wear especially in the time that road conditions are poor.The unreasonable design of valve rocker also can make valve rocker stressed unreasonable, and valve rocker 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 rocker is provided, and its technological scheme is as follows:
A kind of valve rocker, it is characterized in that, described valve rocker comprises intermediate arm body, described intermediate arm body is provided with boss, on described boss, offer rocker shaft hole, between described rocker shaft hole and boss, pass through arc surface transition, one end of described intermediate arm body is connected with valve arm, the other end of described arm body is connected with fulcrum rocking arm, the end of described fulcrum rocking arm offers fulcrum attachment hole, in described fulcrum attachment hole, offer internal thread, between described fulcrum attachment hole and the end of fulcrum rocking arm, be connected by arc inner concave, spacing between described rocker shaft hole and valve arm is greater than the spacing between fulcrum rocking arm and rocker shaft hole.
The valve rocker that the utility model provides, when in use, is connected with controlling rod and uses as controlling whole valve rocker in rocker shaft hole.And fulcrum attachment hole is connected with driveshaft, driveshaft provides power.Valve arm is connected with valve.Pull moving up and down of fulcrum rocking arm.And the motion of fulcrum rocking arm is taking controlling rod as fulcrum, thereby valve arm is moved up and down, thereby reached the object of opening and sealing valve.Spacing between described rocker shaft hole and valve arm is greater than the spacing between fulcrum rocking arm and rocker shaft hole.Because the spacing between rocker shaft hole and valve arm is greater than the spacing between fulcrum rocking arm and rocker shaft hole, so make valve arm pull very quick, laborsaving of valve.
The utility model is simple in structure, can be good at reducing the stress that spring block is subject to, and can strengthen greatly working strength, increases working life.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of valve rocker, it is characterized in that, described valve rocker comprises that the intermediate arm body 1 described in intermediate arm body 1 is provided with boss 2 described in boss 2 and offers 2 of rocker shaft hole 3 boss described in rocker shaft hole 3 by arc surface transition, described intermediate arm body 1 one end is connected with intermediate arm body 1 the other end described in valve arm 4 and is connected with the fulcrum attachment hole 6 that fulcrum Rocker arm 5 end described in fulcrum Rocker arm 5 offers described in fulcrum attachment hole 6 and offers internal thread, between described fulcrum attachment hole 6 fulcrum Rocker arm 5 ends, be connected by arc inner concave, the spacing that described rocker shaft hole 3 valve arm is 4 is greater than the spacing of 3 of fulcrum Rocker arm 5 rocker shaft holes.
The valve rocker that the utility model provides, when in use, is connected with controlling rod and uses as controlling whole valve rocker in rocker shaft hole.And fulcrum attachment hole is connected with driveshaft, driveshaft provides power.Valve arm is connected with valve.Pull moving up and down of fulcrum rocking arm.And the motion of fulcrum rocking arm is taking controlling rod as fulcrum, thereby valve arm is moved up and down, thereby reached the object of opening and sealing valve.
