The preloading and retraction device (10, 10 ') of the wheel assembly comprises: a linear guide (11); an inner slide (12) and an outer slide (13) movable along the linear guide (11); a linear elastic member (14) arranged to connect the two sliders (12) (13); a first wheel support arm (15) integral with the inner slider (12); and a second wheel support arm (19) integral with the outer slide (13) wherein the outer slide (13) carries an actuated weight support wheel (20) and the inner slide (12) carries a traction wheel (16) which is in contact with the rolling surface with a preload force dependent on the geometry of the system. The use of the device (10, 10 ') is particularly advantageous for supporting the wheels of a self-propelled cart (100) of the type adapted to move along a railway track for inspecting the underbody of a railway vehicle, this is because the device greatly facilitates mounting automation of the self-propelled cart (100) on the rail and at least partially mounting the self-propelled cart on the rail.

    轮组件的预加载及缩回装置(10、10’)包括:线性的引导件(11);能够沿着线性的引导件(11)移动的内部滑动件(12)和外部滑动件(13);被布置成将两个滑动件(12)(13)连接的线性的弹性构件(14);与内部滑动件(12)成一体的第一轮支撑臂(15);以及与外部滑动件(13)成一体的第二轮支撑臂(19),其中,外部滑动件(13)承载有被致动的重量支撑轮(20),并且内部滑动件(12)承载有牵引轮(16),该牵引轮以与系统的几何形状有关的预加载力与滚动表面接触。该装置(10、10’)的使用特别有利于对适于沿着铁路轨道移动以用于对铁路交通工具的车身底部进行检查的类型的自推进式推车(100)的轮进行支撑,这是因为该装置大大促进将自推进式推车(100)安装在铁轨上并且至少部分地使自推进式推车安装在铁轨上的安装自动化。
