Embodiment Construction

[0021] figure 1 It is a structural schematic diagram of the present invention, figure 2 It is a structural schematic diagram of the limiting block of the present invention, image 3 It is a structural schematic diagram of the rocker arm of the present invention; Figure 4 It is a structural schematic diagram of the rocker arm seat of the present invention. As shown in the figure, the valve rocker arm assembly of this embodiment includes a rocker arm seat 1 and a rocker arm 3; the rocker arm 3 is supported on the rocker arm seat 1 and forms a The rocker arm 3 is a matching pair that swings relative to the rocker arm seat 1. The rocker arm 3 is provided with a limit block 5 that makes it swing and cooperate with the rocker arm seat 1 in a single degree of freedom. The rocker arm 3 can swing through the matching pair. It is directly supported on the rocker arm base 1, so there is no need to use rocker shafts and other parts to rotatably connect the rocker arm 3 to the rocker a...

Abstract

The invention discloses a valve rocker arm assembly. The valve rocker arm assembly comprises a rocker arm support and rocker arms, wherein the rocker arms are supported on the rocker arm support and form a cooperation pair for enabling the rocker arms to swing relative to the rocker arm support; the rocker arms are horizontally limited relative to the rocker arm support. According to the valve rocker arm assembly provided by the invention, the rocker arms are in direct contact with the rocker arm support, are supported on the rocker arm support, and are rotatably connected with the rocker arm support without rocker arm shafts, so that the assembly process of an engine is greatly simplified, and the number of parts of the valve rocker arm assembly of the engine is decreased; on the other hand, the rocker arms are horizontally limited relative to the rocker arm support, so that the rocker arms are guaranteed to swing in the planes of a valve and a valve push rod all the time, and abrasion of valve parts such as the valve push rod is avoided during the working process of the rocker arms.

Description

technical field [0001] The invention relates to the field of engine components, in particular to a valve rocker arm assembly and an engine thereof. Background technique [0002] The valve rocker arm is an important component of the engine valve rocker arm assembly. Its function is to drive the valve to open through its reciprocating swing. The traditional engine valve rocker arm assembly (including valve rocker arm, valve bolt, and valve adjustment nut) is installed in the following ways: The rocker arm seat is installed on the cylinder head, and the rocker arm is installed on the rocker arm seat through the rocker shaft, resulting in more parts in the traditional valve rocker arm combination, and the rocker arm seat structure is more complicated and usually needs to be fixed by three to four bolts. The rocker arm seat is installed on the cylinder head, the cost is high, the installation is more complicated, and the processing cost of the cylinder head is greatly increased. ...
