    • A bearing device for a wheel enabling a reduction in weight and size and the number of parts and capable of preventing rain water and dust from entering therein and differential gear oil from leaking, comprising an inside member (3) having a hub wheel (1) in which a bearing for the wheel is installed in an opening part between an axle tube (H) supported on the lower surface of a vehicle body and a drive shaft (D/S) inserted into the axle tube and the bearing for the wheel is formed integrally with a wheel mounting flange (6) at one end and a cylindrical part (7) is formed thereon and an inner ring (10) press-fitted into the cylindrical part (7), an outer member (4) inserted onto the inner member (3), and multiple rows of rolling elements (5) rollingly stored between the inner member (3) and the outer member (4). The inner ring (10) is prevented from coming off in the axial direction by a clamping part (13) formed by elastically deforming the end part of the cylindrical part (7) in the radial outer direction. A cap (9) formed of a steel plate core (9a) formed in a generally channel shape in cross section and an elastic member (9b) joined to the fitting part of the core (9a) is press-fitted into the inner diameter part of the wheel mounting flange (6).
    • 一种用于车轮的轴承装置,其能够减轻重量,尺寸和部件数量,并且能够防止雨水和灰尘进入其中,并且差速齿轮油不会泄漏,包括具有轮毂轮(1)的内部构件(3) 其中用于车轮的轴承安装在支撑在车身下表面的轴管(H)和插入车轴管的驱动轴(D / S)之间的开口部分和用于车轮的轴承 与其一端的车轮安装凸缘(6)一体形成,并且在其上形成有圆柱形部分(7),并且内圈(10)压配合到圆柱形部分(7)中,外部构件(4)插入到 内部构件(3),以及多列滚动体(5),其滚动地存储在内部构件(3)和外部构件(4)之间。 通过在圆筒部(7)的径向外侧弹性变形而形成的夹紧部(13),能够防止内圈10在轴向上脱落。 由形成为大致通道形状的钢板芯(9a)形成的盖(9)和与芯(9a)的嵌合部接合的弹性构件(9b)压配合到内径部 的轮安装法兰(6)。
