An electric bicycle drive unit fixing structure (50) by which an electric mid-motor drive unit (30) is floatingly attached to a drive receptacle (21) of a bicycle frame (20) wherein the drive receptacle (21) comprises two mutually parallel frame flanges (211, 212) fixed to the frame and vertical, and wherein a drive unit housing (34) comprises two parallel and vertical housing flanges (41, 42), wherein one housing flange (41) is attached to one frame flange (211) and the other housing flange (42) is attached to the other frame flange (212), respectively defining a pair of flanges, and wherein two pairs of flanges respectively comprise at least one rubber bearing (80) through which the frame flanges (211, 212) are connected in a floating and rubber elastic manner to the associated housing flange (41, 42), the housing flanges (41, 42) are arranged such that the housing flanges (41, 42) do not directly abut against the corresponding frame flanges (211, 212) in each case but are spaced apart from the corresponding frame flanges (211, 212) by a spacing gap (58) having a gap dimension X of at least 0.3 mm.

    一种电动自行车驱动单元固定结构(50),通过该结构,电动中置马达驱动单元(30)浮动地附接到自行车车架(20)的驱动容座(21),其中该驱动容座(21)包括两个相互平行的固定到车架且竖直的车架凸缘(211、212),其中驱动单元壳体(34)包括两个平行且竖直的壳体凸缘(41、42),其中一个壳体凸缘(41)附接到一个车架凸缘(211)且另一壳体凸缘(42)附接到另一车架凸缘(212),分别限定凸缘对,并且其中两个凸缘对分别包括至少一个橡胶支座(80),车架凸缘(211、212)通过该橡胶支座以浮动且橡胶弹性的方式连接至相关联的壳体凸缘(41、42),使得壳体凸缘(41、42)在每种情况下不直接抵靠对应的车架凸缘(211、212),而是通过具有至少0.3mm的间隙尺寸X的间隔间隙(58)与对应的车架凸缘(211、212)间隔开。
