    • A gear comprises a hub and a gear ring mounted thereon, each formed with peripherally spaced apertures and interlocking elements extending peripherally between adjacent apertures to hold the hub and gear ring against axial movement relative to each other. The apertures of the hub and gear ring register. Torque is transmitted between the hub and gear ring by a plurality of first abutments on the hub which have radially outwardly facing surfaces adjoining respective apertures therein, a plurality of second abutments on the gear ring which have radially inwardly facing surfaces adjoining respective apertures therein and radially aligned with respective outwardly facing surfaces, and a plurality of prestressed elastomeric spring elements disposed in the registering apertures. Each spring element engages the radially aligned surfaces and is retained in the apertures by a retaining disc secured to the hub and engaging the spring element on one side of the gear.
    • 齿轮包括安装在其上的毂和齿圈,每个形成有周向间隔开的孔和在相邻孔之间周向延伸的互锁元件,以保持轮毂和齿圈相对于彼此的轴向移动。 轮毂和齿圈的孔径注册。 扭矩通过轮毂上的多个第一邻接件在轮毂上传递,所述多个第一邻接件具有邻接其中相应孔的径向向外的表面;齿轮环上的多个第二邻接部,其具有邻接其中的各个孔的径向向内的表面, 与相应的向外表面对齐,以及设置在配准孔中的多个预应力弹性体弹簧元件。 每个弹簧元件接合径向对准的表面并且通过固定到轮毂并与齿轮的一侧上的弹簧元件接合的保持盘保持在孔中。

    • A drive for a road wheel mounted in the frame of a motor-assisted bicycle comprises a drive housing pivotal transversely to the plane of the wheel and connected to the frame by an interposed elastomeric sleeve deformable by the pivotal movement of the drive housing. An engine in the housing has a crankshaft and a drive shaft is non-rotatably connected to the crankshaft. A bevel wheel is non-rotatably mounted on the drive shaft and a pressure roller is aligned with the bevel wheel in the axial direction of the road wheel, the bevel wheel and pressure roller being engageable with the road wheel on opposite sides thereof. A spring arm secured to the housing and carrying the pressure roller normally urges the bevel wheel and pressure roller into engagement with the respective sides of the road wheel. A rotatable spreading cam pivoted to the housing and disposed between the housing and the spring arm is manually operable to move the spring arm away from the housing so as to move the roller out of engagement with the road wheel and a stop on the frame engages the spring arm on further manual operation of the cam to retain the spring arm to perform the pivotal movement of the housing under the elastic deformation of the sleeve to disengage the bevel wheel from the road wheel.
    • 用于安装在电动辅助自行车车架上的车轮的驱动器包括驱动壳体,其横向于车轮的平面枢转,并通过由驱动器壳体的枢转运动可变形的插入的弹性套筒连接到框架。 壳体中的发动机具有曲轴,并且驱动轴不可旋转地连接到曲轴。 斜齿轮不可旋转地安装在驱动轴上,压轮与轮轮在轴向方向上对准,斜齿轮和压力辊可与其轮的相对侧啮合。 固定在壳体上并承载压力辊的弹簧臂通常促使斜齿轮和压力辊与车轮的相应侧面接合。 枢转到壳体并且设置在壳体和弹簧臂之间的可旋转的撒布凸轮可手动地操作以使弹簧臂远离壳体移动,以便使辊移动离开与车轮的接合,并且框架上的止动件接合 弹簧臂进一步手动操作凸轮以保持弹簧臂,以在套筒的弹性变形下执行壳体的枢转运动,以使斜齿轮与车轮分离。
