Abstract

The invention discloses a concave-convex wheel rocker arm type valve distribution mechanism. The concave-convex wheel rocker arm type valve distribution mechanism comprises a cylinder cover, wherein a vertical shaft and two rocker arm frames are arranged on the cylinder cover; a concave-convex wheel is arranged on the vertical shaft; conical teeth are arranged at the top of the concave-convex wheel; conical gears are arranged on the conical teeth and are located on a horizontal shaft; the gear ratio of the conical teeth to the conical gears is 2 to 1; the two rocker arm frames are respectively arranged on two radial positions of the concave-convex wheel; the inclined angle between the two radial positions is 90 DEG; and T-shaped rocker arms are arranged on the rocker arm frames. An internal combustion engine matched with the concave-convex wheel rocker arm type valve distribution mechanism is provided with concave-convex wheel rocker arm type valve distribution mechanisms with the same number as cylinders; the horizontal shafts of the valve distribution mechanisms are integrally connected, are located on shaft frames and are connected with crankshafts through driven chain wheels, chains and drive chain wheels; and the driven chain wheels have the same tooth number as the drive chain wheels. The concave-convex wheel rocker arm type valve distribution mechanism is simple in structure and convenient to manufacture, is reliable in performance and can tightly close and easily open the valve, is less in internal consumption, high in efficiency and more oil-saving, and can fully open the valve for conveniently sucking and exhausting air.

Description

Technical field [0001] The invention relates to a gas distribution mechanism and a matching internal combustion engine, in particular to a convex-concave wheel rocker arm type gas distribution mechanism and a matching internal combustion engine. Background technique [0002] The current internal combustion engine still uses the original valve mechanism composed of cams and valve springs. The mechanism is composed of camshafts, cams, valve springs, valves and other components. The cam is arranged on the camshaft, the cam wheel is pressed on the top of the valve, the valve spring is sleeved on the valve, the camshaft is driven by the crankshaft, and the cam rotates with the camshaft. When the cam rotates, the convex part and the circumference of the cam will Alternately turn to the top of the valve. When the convex portion turns to the top of the valve, the valve spring will be pressed to open the valve. When the circumference turns to the top of the valve, the valve spring will re...
