A wheel unit with a disengageable drive for an electric vehicle comprises: a wheel support (4); a hub (1) rotatably supported by the wheel support (4); and a wheel pin (5) carried by a component driven by an electric motor and rotatably mounted in the hub (1) by means of two rolling bearings (19, 20). A coupling device (15) releasably connects the driven part (6) to the hub (1). Two rolling bearings (19, 20) rotatably supporting the wheel pin (5) have respective outer rings (19A, 20A) mounted by interference fit in a centrally open cylindrical wall (7) of the hub and respective inner rings (19B, 20B) rigidly connected together by means of a spacer sleeve (21) of strictly predetermined length. A wheel-hub (1) unit (M) with two rolling bearings (19, 20) and a spacer sleeve (21) can be assembled prior to being mounted on the wheel pin (5).
用于电动运载工具的具有可断开接合的驱动器的轮单元包括:轮支承件(4);轮毂(1),其由轮支承件(4)可旋转地支承;以及轮销(5),其借助于两个滚动轴承(19、20)来由被电动马达驱动并且可旋转地安装于轮毂(1)内的部件承载。联接装置(15)使所述从动部件(6)以可释放方式连接到轮毂(1)。旋转地支承轮销(5)的两个滚动轴承(19、20)具有通过干涉配合来安装于毂的中心开口的柱形壁(7)内的相应的外环(19A、20A)和借助于具有严格地预确定的长度的间隔套筒(21)来刚性地连接在一起的相应的内环(19B、20B)。具有两个滚动轴承(19、20)和间隔套筒(21)的轮‑毂(1)单元(M)可在安装于轮销(5)上之前被组装。
