一种重型越野汽车前转向驱动桥用整体式转向节结构
本技术涉及一种重型越野汽车零部件,尤其涉及一种重型越野汽车前转向驱动桥用整体式转向节结构。
技术介绍
国内现有的重型越野汽车转向驱动桥主要采用斯太尔技术,其转向节、轴头、轴叉、主销、桥壳及其他组件组成了转向驱动桥的转向机构。其中,转向节与轴头、轴叉与桥壳分别采用螺栓连接,转向节绕主销旋转,以实现转向驱动桥的转向功能。这种结构有一些缺点,如结构复杂、装配工艺冗繁,同时由于轴叉及桥壳连接螺栓的限制造成桥壳法兰处成为应力集中点,影响整桥的总体承载能力。
技术实现思路
本技术是针对现有技术所存在的不足,而提供了一种结构简单、设计合理,整体强度高,且装配工艺简单、易操作的一种重型越野汽车前转向驱动桥用整体式转向节结构。为了实现上述目的,本技术提供了一种重型越野汽车前转向驱动桥用整体式转向节结构,包括整体式转向节及一体式前驱动桥壳,一体式前驱动桥壳连接上主销及下主销,整体式转向节绕上下主销转动;整体式转向节及一体式前驱动桥壳中部贯穿万向传动轴,万向传动轴采用滚针轴承支撑;上主销与一体式桥壳之间有调整垫片;整体式转向节与转向节臂上有通气孔 ...
