Abstract
本发明涉及商用车制动间隙自动控制技术领域，公开了一种多连杆机构自动调整臂，包括壳体，壳体的下部贯通开设有蜗轮腔，蜗轮腔内部转动设置有蜗轮；壳体的上部贯通开设有蜗杆安装孔，蜗杆安装孔内转动设置有蜗杆，蜗杆为同轴一体结构，蜗杆中部为螺旋齿段，蜗杆的两端为光轴段，蜗轮与蜗杆的螺旋齿段啮合传动；壳体的上部还设有与蜗杆安装孔垂直的轴向组件安装孔，轴向组件安装孔为非贯通孔，轴向组件安装孔内设置有芯轴组件，芯轴组件包括轴向穿过轴向组件安装孔并可以在轴向组件安装孔内转动的芯轴。本发明蜗轮齿不用借助工具，保养时随手实现新齿进入啮合位置，达到负载均摊目的，延长使用寿命。控制臂新解决方案使蜗轮蜗杆模数增加更便捷，从而提升重载能力，工况适应性更强。
