What is the composition of the valve train?

The valve train consists of valve train, camshaft and components, rocker shaft and components, valve push rod, valve, cylinder head, valve seat, valve sleeve, valve spring, valve lock piece and components, and valve adjusting screw. The following is the related introduction: camshaft: it is the main component of the valve drive group, and its function is to control the opening and closing of the valve and the change law of its lift. Lower camshaft engine: Camshafts are also used to drive gasoline pumps, oil pumps, power distributors and other equipment. Stud: The function is to transfer the driving force generated when the camshaft rotates to the push rod (lower and middle camshaft) or the valve (overhead camshaft). The cone is generally made of alloy steel or alloy cast iron with good wear resistance. Push rod: There is a slender push rod in the valve mechanism of the lower camshaft. The function of push rod is to transfer the driving force of cam from tappet to rocker mechanism. Rocker: its function is to change the direction of the force of the push rod or cam, and then transfer the force to the valve to open it. The rocker arm assembly is mainly composed of rocker arm, rocker arm shaft, bearing seat, valve clearance adjustment screw and other parts.
