Abstract

The invention discloses a rocker arm assembly. The rocker arm assembly comprises a rocker arm shaft, and a rocker arm body is installed on the circumferential face of the rocker arm shaft, one end, far away from the rocker arm shaft, of the rocker arm is provided with an ejection column, a cam shaft is arranged on the right side of the rocker arm, and a cam is arranged on the circumferential faceof the cam shaft in an installing mode, and a valve rod is arranged below the cam; a valve spring and a valve base are installed on the circumferential face of the valve rod, a spring base is arrangedbelow the rocker arm shaft, an installing groove is formed in the rocker arm, and a rocker arm spring is installed between the spring base and the installing groove. According to the rocker arm assembly, the phenomena of untight air valve closing and air leakage are effectively prevented, and the contact occurred between the rocker arm body and the air valve in an oscillating environment is avoided, the working reliability of an air distribution mechanism is ensured, and the noise during working of the air distribution mechanism is reduced.

Description

technical field [0001] The invention relates to the field of rocker arms, in particular to a rocker arm assembly. Background technique [0002] The rocker arm is one of the important parts of the engine mechanism. Its main function is to transmit the rotational motion of the camshaft to the valve through the rocker arm, so as to control the opening and closing of the valve according to a certain rule. The use of the rocker arm can also make the arrangement of the camshaft and the adjustment of the valve clearance setting very convenient. When the engine is working, in order to prevent the related parts of the valve and the rocker arm from being heated and elongated, the valve is not closed tightly, and there is a certain gap between the end of the valve stem and the rocker arm, which is called the valve clearance. Due to the existence of the valve clearance, the rocker arm and the valve will collide frequently in a oscillating environment, resulting in rapid wear of the con...
