The invention relates to a coaxial wheel assembly which comprises a wheel set base, a walking wheel assembly, a guide wheel assembly, an inter-wheel axial position adjusting assembly, a common shaft, a wheel shaft axial position adjusting assembly, a locking spacer bush, a locking and locknut and a common shaft fixing block. The guide wheel assembly, the inter-wheel axial position adjusting assembly, the walking wheel assembly and the locking spacer bush are sequentially connected in a sleeved mode and axially fastened to the common shaft through the locking and anti-loosening nut, the common shaft is fixedly connected into the wheel set base through the common shaft fixing block, and the axial position of the common shaft on the wheel set base can be adjusted through the wheel shaft axial position adjusting assembly. The traveling wheel assembly and the guide wheel assembly are coaxially mounted on the obliquely arranged common shaft, so that the purposes of simplifying the structure of the wheel assembly, reducing the weight, reducing the manufacturing and mounting difficulty of a wheel train, increasing the diameter of a wheel shaft of a guide wheel and increasing the specification of a supporting bearing are achieved, and the precision of the wheel assembly of the rail inspection trolley is effectively improved; meanwhile, the device can smoothly pass through a rim groove of a turnout zone and is prevented from colliding with a guard rail, and the aim of effectively avoiding fat edges of the steel rail is achieved.

    本发明涉及一种共轴式车轮组件,包括轮组基座、走行轮组件、导向轮组件、轮间轴向位置调整组件、公共轴、轮轴轴向位置调整组件、锁紧隔套、锁紧及防松螺母、公共轴固定块,所述导向轮组件、轮间轴向位置调整组件、走行轮组件、锁紧隔套依次套接并由锁紧及防松螺母轴向紧固在公共轴上,公共轴由公共轴固定块固定连接在轮组基座中,并可通过轮轴轴向位置调整组件调整公共轴在轮组基座上的轴向位置。本发明通过在倾斜设置的公共轴上共轴安装走行轮组件和导向轮组件,达到简化车轮组件的结构、降低重量、降低轮系制造和安装难度、增大导向轮的轮轴直径和增大支承轴承规格、有效提高轨检小车车轮组件精度,同时能够顺利通过道岔区的轮缘槽并防止与护轨发生碰撞、有效避让钢轨肥边的目的。
