Abstract: PURPOSE: An axial force reduction-type tripod constant velocity joint is provided to reduce vibration and noise generated in a vehicle by reducing axial force of the constant velocity joint by improving components. CONSTITUTION: An axial force reduction-type tripod constant velocity joint is composed of three axial track grooves axially formed to a housing(1) at regular intervals; a spider(2) mounted in the housing and formed with three protruded trunnions; and a needle roller(4) and a spherical roller(3) installed around the outer periphery of each trunnion. In addition, a disc bearing(8) and a bearing supporting bar(9) comprising a taper bearing and a ball bearing are installed between the needle roller and the spider. The spider for operating angle rotates with rolling-contacting on the disc bearing and the spherical roller is guided by the guide surface of the housing with being parallel to the axis of the housing. Accordingly, friction resistance generated between the track groove guide surface of the housing and the spherical roller is reduced.
Abstract translation: 目的：提供轴向力减小型三球架等速万向节，以通过改善部件减小等速万向节的轴向力来减少车辆产生的振动和噪音。 构造：轴向力减小型三球架等速万向节由三个轴向轨道槽构成，轴向轨道槽以规则的间隔轴向地形成到壳体（1）上; 安装在壳体中并形成有三个突出的耳轴的星形架（2） 以及安装在每个耳轴的外周周围的滚针（4）和球面滚子（3）。 此外，在滚针和蜘蛛之间安装有圆盘轴承（8）和包括锥形轴承和滚珠轴承的轴承支撑杆（9）。 操作角度的蜘蛛在圆盘轴承上滚动接触而旋转，球面滚子由壳体的引导表面平行于壳体的轴线引导。 因此，减小了在壳体的轨道槽引导表面和球面滚子之间产生的摩擦阻力。
