Abstract

The invention discloses a rock arm assembly. The rocker arm assembly is arranged on a cylinder cover of a cylinder of an engine, and comprises rocker arms and a connecting portion, wherein the connecting portion comprises a base fixedly connected with the cylinder cover and a connecting shaft arranged on the base; the rocker arms are pivoted to the connecting shaft. The rocker arm assembly is simple in structure, has high integration degree, can be independently applied to the cylinder cover of the cylinder, and is convenient to assemble and disassemble. The interference during assembling of the rocker arms of each cylinder is avoided effectively, and the working performance of each cylinder is ensured reliably. On the basis, an engine applying the rocker arm assembly is further provided.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a rocker arm assembly. In addition, the invention also relates to an engine using the rocker arm assembly. Background technique [0002] The rocker arm system is applied to the cylinder of the engine and is one of the important parts of the engine work. Each rocker arm assembly in the rocker arm system is supported on the cylinder head of the cylinder through its rocker arm seat, and the rocker arm in the rocker arm assembly reciprocates to transmit the power from the tappet to the valve to open the engine valve. Therefore, the rocker arm of the rocker arm assembly needs to correspond accurately to the valve of the corresponding cylinder to ensure the reliable working performance of the engine. [0003] Currently, if figure 1 As shown, the integrated rocker arm system 10' is widely used on the engine. Taking a four-cylinder engine as an example, each rocker arm assembly 100' ...
