Problems solved by technology
The unreasonable design of the rocker arm for automobiles will also cause unreasonable force on the valve rocker arm, and cracks will appear on the valve rocker arm from the stress concentration point, and it will break after long-term movement
Moreover, the current automobile rocker arm is easily damaged due to the large friction between the automobile rocker arm and the bearing after being used for a period of time, and it is troublesome to refuel and lubricate.

The invention belongs to the technical field of automobile parts and tools, and particularly relates to a rocker arm for an automobile. The rocker arm for the automobile comprises a middle arm body, wherein the two end parts of the middle arm body are connected with two connecting shaft rods corresponding to each other; connecting holes are formed in axial directions of the connecting shaft rods; oil feed grooves are formed in the two sides, of a connection column, of the middle arm body; one end of each oil feed groove penetrates through the connection column and then is communicated with a through hole; the other ends of the oil feed grooves are positioned at the two end parts of the middle arm body; and the oil feed grooves are formed in parallel to straight edges with the equal lengths as those of the oil feed grooves. The rocker arm for the automobile has the beneficial effects that the rocker arm for the automobile is reasonable in structure; the service time can be prolonged well; and oiling for lubrication can be performed very conveniently.
Description
technical field [0001] The invention belongs to the technical field of automobile parts and appliances, and in particular relates to a rocker arm for automobiles. Background technique [0002] The rocker arm for automobile 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 rocker arm and the control rod and the drive rod for automobiles is large, and the long-term frictional contact, especially between the valve rocker arm, the control rod and the drive rod under poor road conditions, will cause abnormal wear of the valve rocker arm for a long time. The unreasonable design of the rocker arm for automobiles will also cause unreasonable force on the valve rocker arm, and cracks will appear on the valve rocker arm from the stress concentration point, and it will break after long-term movement. Moreover, the current rocking arm f...
