    • A two-wheel and four-wheel driving change-over device for a vehicle is provided. A change-over unit intermittently performs power transmission for the power transmission mechanism. The change-over unit includes a driving shaft connected to a driving side, a driven shaft fitted to the driving shaft with an annular clearance therebetween. A plurality of engaging or disengaging members installed in a clearance between the driving shaft and driven shaft are engaged with or disengaged from the opposing surfaces for performing a connecting operation and a disconnecting operation between the driving shaft and driven shaft. A change-over mechanism is provided for selectively positioning the engaging or disengaging members between a position where the driving shaft and driven shaft are connected and a position where the driving shaft and driven shaft are disconnected.
    • 提供一种用于车辆的两轮和四轮驱动转换装置。 切换单元间歇地执行动力传递机构的动力传递。 转换单元包括连接到驱动侧的驱动轴,与驱动轴配合的从动轴,其间具有环形间隙。 安装在驱动轴和从动轴之间的间隙中的多个接合或分离构件与相对的表面接合或脱离,用于执行连接操作和驱动轴和从动轴之间的断开操作。 提供了一种转换机构,用于在接合或分离构件在驱动轴和从动轴连接的位置与驱动轴和从动轴断开的位置之间选择性地定位。

    • A drum brake includes a brake drum attached to an axle, and a brake panel. The brake drum includes a disc portion and a cylindrical portion extending from an outer peripheral end portion of the disc portion towards the brake panel. On an outer peripheral end portion of the cylindrical portion, there is mounted a seal member. The brake panel includes an annular flat surface portion, and a cylindrical projecting portion projecting from an outer peripheral end portion of the annular flat surface portion towards the brake drum so as to surround the seal member. The seal member has plural resilient axial sealing lips and at least one resilient radial sealing lip. The axial sealing lips are in sealing contact with the annular flat surface portion, and the radial lip is in sealing contact with an inner peripheral surface of the cylindrical projecting portion. Even if the brake drum is axially displaced away from the brake panel due to accidental bending of the axle, the radial sealing lip remains sealingly contact with the inner peripheral surface of the projecting portion.
    • 鼓式制动器包括附接到轴的制动鼓和制动面板。 制动鼓包括盘部分和从盘部分的外周端向制动盘延伸的圆柱形部分。 在圆筒部的外周端部安装有密封部件。 制动面板包括环形平坦表面部分和从环形平坦表面部分的外周端部向制动鼓突出以便围绕密封件的圆柱形突出部分。 密封构件具有多个弹性轴向密封唇缘和至少一个弹性径向密封唇缘。 轴向密封唇与环形平坦表面部分密封接触,并且径向唇缘与圆柱形突出部分的内周表面密封接触。 即使由于轴的意外弯曲使制动鼓轴向移动离开制动面板,径向密封唇保持与突出部分的内周表面密封接触。
