Problems solved by technology

The material hardness difference between the valve rocker arm and the control rod and the drive rod is large, and the long-term frictional contact, especially between the valve rocker arm, the control rod and the drive rod when the road conditions are poor, will cause abnormal wear of the valve rocker arm for a long time
The unreasonable design of the valve rocker arm will also cause unreasonable force on the valve rocker arm, and the valve rocker arm will crack from the stress concentration point, and it will break after long-term movement

Embodiment Construction

[0008] Combine below figure 1 Specific description embodiment:

[0009] A valve rocker arm, characterized in that the valve rocker arm includes the intermediate arm body 1 described in the intermediate arm body 1 provided with the boss 2 described in the boss 2 opened with the rocker shaft hole 3 described in the rocker Arm shaft hole 3 and boss 2 are transitioned through a circular arc surface. One end of the intermediate arm body 1 is connected to the air valve rocker arm 4. The other end of the intermediate arm body 1 is connected to the fulcrum rocker arm 5. 5. The end is provided with a fulcrum connection hole 6. The fulcrum connection hole 6 is provided with an internal thread. The fulcrum connection hole 6. The ends of the fulcrum rocker arm 5 are connected by an arc-shaped inner concave surface. The shaft hole of the rocker arm 3. The distance between the rocker arms 4 of the air valve is greater than the distance between the shaft holes 3 of the rocker arm 5 of the f...

Abstract

The invention belongs to the technical field of automobile part tools, and particularly relates to a valve rocker arm. The valve rocker arm comprises a middle arm body, wherein a boss is arranged on the middle arm body, a rocker arm shaft hole is formed in the boss, the rocker arm shaft hole and the boss are in transition through a circular-arc-shaped surface, internal threads are formed in a supporting point connecting hole, the supporting point connecting hole is connected with the end of a supporting point rocker arm through an arc-shaped inwards-concave surface, and the separation distance between the rocker arm shaft hole and an air valve rocker arm is larger than the separation distance between the supporting point rocker arm and the rocker arm shaft hole. The valve rocker arm is simple in structure, stress borne by a leaf spring seat can be well reduced, use intensity can be greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile parts and appliances, and in particular relates to a valve rocker arm. Background technique [0002] The valve rocker arm is a part of the auto parts, and it is mainly used to cooperate with the camshaft to open the door in time to complete the intake and exhaust of the engine. The material hardness difference between the valve rocker arm and the control rod and the drive rod is large, and the long-term frictional contact, especially between the valve rocker arm, the control rod and the drive rod when the road conditions are poor, will cause abnormal wear of the valve rocker arm for a long time. The unreasonable design of the valve rocker arm will also cause unreasonable force on the valve rocker arm, and the valve rocker arm will crack from the stress concentration point, and it will break after long-term movement. Contents of the invention [0003] The purpose of the present invention is t...
