The invention relates to a railway vehicle chassis end structure which comprises an end beam, a traction beam and a corrugated floor. An unhooking protection device and a tripping prevention impact seat are arranged on the end beam, angle steel is arranged on the rear portion of the end beam and connected with the corrugated floor in a welded mode, a ribbed plate is welded to the portion between the end beam and the angle steel, connecting plates are further welded to protective cases of the unhooking protection device, and the connecting plates are welded to the traction beam. According to the railway vehicle chassis end structure, the angle steel splicing welding structure is adopted by the end beam, the relation between the end beam and a welding connector of the corrugated floor is optimized, and the situation that the corrugated floor structure is adopted by vestibules is achieved; the structure is simpler, and manufacture is convenient. By means of the novelly designed impact seat, the problem of interference with a diaphragm windshield frame can be solved, and the situation that a draw gear jump upwards and cracks up windshield aluminum profile can be effectively prevented. The unhooking protection device can effectively pulls a vehicle to a nearby maintenance point under the condition of unhooking.
