In at least one embodiment, a drive device (1) for an electric bicycle (100) has a shaft (3) and a reversing transmission (2). The reversing transmission is configured to be coupled to the electric motor on one side and to the shaft on the other side such that torque can be transmitted from the electric motor to the shaft via the reversing transmission. The reversing transmission has a first transmission element (21) which can be rotated about a first axis (A1) and a second transmission element (22) which is coupled to the first transmission element. The second transmission element (22) is rotatable about a second axis (A2) running obliquely to the first axis. The drive device is configured for transmitting torque from the first transmission element to the shaft by coupling between the first transmission element and the shaft, and is further configured for rotating the shaft relative to the first transmission element in a first rotational direction. The first transmission element is also axially movable parallel to the first axis within a predetermined limit relative to the second transmission element, wherein the transmission elements remain coupled to each other within the predetermined limit.

    在至少一个实施方式中,用于电动自行车(100)的驱动设备(1)具有轴(3)和换向变速器(2)。换向变速器配置用于一方面与电动机耦联并且另一方面与轴耦联,使得扭矩能够从电动机经由换向变速器传递到轴上。换向变速器具有能够围绕第一轴线(A1)旋转的第一传动元件(21)和与第一传动元件耦联的第二传动元件(22)。第二传动元件(22)能够围绕倾斜于第一轴线伸展的第二轴线(A2)旋转。驱动设备配置用于通过在第一传动元件和轴之间的耦联将扭矩从第一传动元件传递到轴上,并且还配置用于将轴沿第一旋转方向相对于第一传动元件旋转。第一传动元件还能够平行于第一轴线在预定的界限内相对于第二传动元件轴向移动,其中在预定的界限内传动元件保持彼此耦联。
