    • A vehicle wheel bearing apparatus which reduces weight, size and number of parts prevents ingress of rain water or dusts and leakage of differential gear oil is structured as a unit with a wheel hub (1,14) and a double row rolling bearing (2, 15). An inner member (3, 16) includes the wheel hub (1, 14) integrally formed with a wheel mounting flange (6) on one end. The wheel hub inner circumferential surface includes a serration (8). An axially extending cylindrical portion (7) extends from the flange (6). One or more inner rings (10) are press-fit onto the cylindrical portion (7) of the wheel hub (1, 14). The inner rings are formed on their outer circumferential surface with at least one of the inner raceway surfaces (10a). An outer member (4) is arranged around the inner member (3, 16). The outer member (4) is formed with double row outer raceway surfaces (4a) on its inner circumferential surface opposite to the inner raceway surfaces (10a). Double row rolling elements (5) are arranged between the inner and outer raceway surfaces (10a, 4a) of the inner member (3, 16) and the outer member (4). A cage (11) freely rollably holds the rolling elements (5). Seals (12) seal an annular space between the inner member (3, 16) and the outer member (4). A partition wall (9) is integrally formed on the wheel hub (1, 14), at its outboard side, to close a central bore of the wheel hub (1, 14).
    • 减轻重量,尺寸和数量的车轮轴承装置防止雨水或灰尘的进入以及差速齿轮油的泄漏被构造为具有轮毂(1,14)和双列滚动轴承(2, 15)。 内部构件(3,16)包括在一端与轮安装凸缘(6)一体形成的轮毂(1,14)。 轮毂内周面包括锯齿(8)。 轴向延伸的圆柱形部分(7)从凸缘(6)延伸。 一个或多个内圈(10)压配合到轮毂(1,14)的圆柱形部分(7)上。 内环在其外圆周表面上与至少一个内滚道表面(10a)形成。 外部构件(4)围绕内部构件(3,16)布置。 外部构件(4)在与内侧滚道面(10a)相反的内周面上形成有双列外侧滚道面(4a)。 双列滚动元件(5)设置在内部构件(3,16)和外部构件(4)的内部和外部滚道表面(10a,4a)之间。 可自由滚动地保持滚动元件(5)的保持架(11)。 密封件(12)密封内部构件(3,16)和外部构件(4)之间的环形空间。 隔离壁(9)在其外侧一体地形成在轮毂(1,14)上,以封闭轮毂(1,14)的中心孔。
