The utility model is provided with a pressure piece, the contact area between the lower bottom surface of the pressure piece and the piston is increased, and the force area of the upper end surface of the piston is increased, so that the force of the piston is uniform and the piston is protected The whole device is divided into the installation part, the connection part and the stress part. The overall volume of the connection part is small, so as to save raw materials and reduce production costs.
【技术实现步骤摘要】
一种排气门摇臂
本技术涉及发动机
,具体为一种排气门摇臂。
技术介绍
气门摇臂的作用是配合凸轮轴适时的打开门,完成发动机的进气和排气;排气门的摇臂一般是如图4所示,摇臂自身有较小的面积与活塞接触,这会导致活塞受力不均匀,长期以往活塞的上表面容易出现凹凸不平的现象。
技术实现思路
本技术的目的在于提供一种排气门摇臂,旨在改善摇臂自身有较小的面积与活塞接触,这会导致活塞受力不均匀的问题。本技术是这样实现的:一种排气门摇臂,包括摇臂主体、轮轴和压件,所述摇臂主体包括安装部、连接部和受力部,所述连接部位于安装部和受力部的中部,所述安装部上开设有安装孔,所述受力部包括空心部和实心部,所述空心部共设置有两个,所述实心部位于两个空心部之间,所述压件包括定位销、压块和泡棉,所述压块的上端通过定位销固定安装在下方的空心部的内部,所述压块的下端面固定有泡棉。进一步的,上方的所述空心部的内部通过轮轴安装有滚轮,且滚轮的上端突出于受力部的上端面。进一步的,所述连接部为两端较粗中间较细的沙 ...
