The invention discloses a flexible rail-clamping travelling wheel assembly. A middle plate and a wheel carrier are disposed within an adjusting base. A guide post is disposed between the middle plate and the wheel carrier; both the middle plate and the wheel carrier can move up and down along the guide post. The lower portion of a locking handle is sleeved with a spring and located between the middle plate and the wheel carrier. The lower end of the wheel carrier is provided with a bottom travelling wheel. Side connecting arms are symmetrically disposed on two sides of the upper portion of the adjusting base. A side connecting rod is hinged to the outer end of each side connecting arm. The lower end of each side connecting rod is provided with a side auxiliary wheel. A frame mounting member is disposed at the lower end of the adjusting base. Two ends of the frame mounting member are hinged to the middles of the side connecting rods, respectively. When the flexible rail-clamping travelling wheel assembly runs, the bottom travelling wheel contacts the upper surface of a steel rail; the side auxiliary wheels are disposed on left and right sides of the steel rail, respectively. The flexible rail-clamping travelling wheel assembly allows the contact of the bottom travelling wheel with the steel rail to be adaptively adjusted and is good in stability.
