The present disclosure provides a bogie frame, a bogie assembly and a rail vehicle. The bogie frame includes a bogie body, the bogie body being substantially rectangular and including a first connecting beam, a second connecting beam, a third connecting beam and a fourth connecting beam which are sequentially connected end to end, where the first connecting beam is opposite to the third connecting beam, the second connecting beam is opposite to the fourth connecting beam, an electric assembly mounting groove is formed in the fourth connecting beam, the thickness of the fourth connecting beam is greater than the thickness of the second connecting beam, and the top wall of the first connecting beam and the top wall of the third connecting beam are connected between the top wall of the second connecting beam and the top wall of the fourth connecting beam in an arc shape.

Some embodiments of the present disclosure provide a chassis component of a railway vehicle, and a railway vehicle. The chassis component includes: two spaced lower boundary beams; and two spaced sleeper beams, provided between the two lower boundary beams along a length direction of the lower boundary beams. At least one of the sleeper beams includes: a web structure; a center pin, connected with a bogie of a railway vehicle; and a mounting frame, connected with the web structure, the center pin being provided on the mounting frame, the mounting frame including a plurality of vertical plates, and the plurality of vertical plates being spaced along an outer wall surface of the center pin. The technical solution of some embodiments of the present disclosure can solve the problem in the related art of insufficient connecting strength of a center pin and a web structure of a sleeper beam.

A rail vehicle, such as a locomotive, has at least one undercarriage with one or more wheel sets and an undercarriage frame. A vehicle body, resiliently supported on the undercarriage, has a vertical pivot pin passing through the undercarriage frame for traction linking the vehicle body. A limiting stop is connected to the pivot pin for limiting the vertical motion of the vehicle body relative to the undercarriage frame. The pivot pin has a horizontal through-hole in a downwardly protruding pin segment for supporting the limiting stop. Contact protrusions of the limiting stop protrude from the through-hole on both sides of the pivot pin. In the event of maximum vertical motion, the limiting stop contacts the undercarriage frame from below by way of the contact protrusions. The entrainment of the undercarriage is thus effected with great safety when the rail vehicle is lifted.

A wheel and tire assembly for material handling machines for selective operation on or off rails include a monolithic, tubular wheel body divided into an inner tire mounting section and an outer rail engaging section. The tire mounting section is bounded by an inner rim projecting around an inner end of the wheel body and an outer rim projecting radially outward around the wheel body medially between the inner and outer ends thereof. A tire is securable around the wheel between the inner and outer rims. A rail engaging flange projects radially outward from the wheel body in outwardly spaced relation from the outer rim in a spacing adapted for reception of a rail, such as a rail formed on an upper end of a rail car sidewall therebetween.
