图1的上述说明也适用于根据本发明的轮轴承单元,其部分地在图2中被示出,并且仅有在图1中附图标记为34的区域不同于图1的轮轴承单元1。图2中示出了根据本发明的轮轴承单元的在图1中用附图标记34指示的区域。在以下描述中,图2的根据本发明的轮轴承单元对相对应的结构保持使用相同的附图标记。
在图2中部分示出的根据本发明的轮轴承单元具有轮毂10,第一滚动轴承12和第二滚动轴承(在图2中未示出)。所述滚动轴承12与轮毂的第一轴向端部相间隔、并与其相对布置。此外所述轮轴承单元还具有固定单元14,其与轮毂分开形成并与轮毂的轴向端部间隔地设置。
固定单元固持滚动轴承12,防止轮轴承单元的重心从轮毂中脱离。为了这个目的,该固定单元包括垫圈28,该垫圈28嵌入轮毂的凹槽26中,由此,垫圈形状配合地相对于所述轮轴承单元的轴向方向22而被固定在轮毂中。垫圈接触凹槽的底部。此外,所述固定单元具有角圈30,其贴靠在滚动轴承12的部件18的轴向端面32上。所述角圈从后面作用在垫圈上,并由此以形状配合的方式相对于轴向方向22被固定在轮毂上。所述部件18是滚动轴承12的内圈。通过将角圈贴靠在端面上,滚动轴承12通过固定单元以形状配合的方式相对于轴向方向22被固定在轮毂上。
所述固定单元由所述角圈和所述垫圈组成。因此,整个固定单元设置在滚动轴承12的轴向的端部区域24上和设置在轮毂内。角圈和垫圈均由金属制成。
固定单元被保持在上述的位置代表一种运输安全方法,其中,滚动轴承12被保持在它的位置并被固定在那。
