An auxiliary traction device (1) for a wheelchair (W), comprising a support structure (2) to which a drive wheel (3) is rotatably coupled, the drive wheel (3) comprising a wheel (31) operatively connected to an electric motor (32), an electronic control unit (4) configured to control the electric motor (32), a connection assembly (6) rotatably associated to the support structure (2), therefore, a steering axis (Y) of the supporting structure (2) and the driving wheel (3) is limited relative to the connecting assembly (6). The auxiliary traction device further comprises a hook-like body (7) defined coaxially with the steering axis (Y), rotatably coupled to the connection assembly (6), and the first end (7a) of which is integrally connected to the support structure (2). The hook-shaped body (7) is provided with a hook-shaped forming piece (71) at a second end (7b) opposite to the first end (7a), so that an external accessory device (200, 300, 400) provided with a reverse piece (205, 304, 401) complementary to the hook-shaped forming piece (71) is allowed to be hooked operatively.

    一种用于轮椅(W)的辅助牵引设备(1),包括支承结构(2)、电子控制单元(4)、连接组件(6),驱动轮(3)可旋转地联接到支承结构(2),驱动轮(3)包括可操作地连接到电动马达(32)的轮(31),电子控制单元(4)构造成控制电动马达(32),连接组件(6)可旋转地关联到支承结构(2),从而相对于连接组件(6)限定支承结构(2)和驱动轮(3)的转向轴线(Y)。该辅助牵引设备还包括钩状体(7),钩状体(7)与转向轴线(Y)同轴地限定,可旋转地联接到连接组件(6),并且其第一端(7a)一体地连接到支承结构(2)。这种钩状体(7)在与第一端(7a)相对的第二端(7b)处设有钩状成形件(71),从而允许设有与钩状成形件(71)互补的反形件(205、304、401)的外部附件设备(200、300、400)的操作性钩住。
