The invention relates to the field of bogies, and discloses a locomotive bogie axle box suspension device which comprises an axle box. The spring set is arranged on the axle box and comprises a spring, an upper spring plate and a lower spring plate, the upper spring plate and the lower spring plate are used for clamping the spring, and the upper spring plate is provided with a boss used for being matched with a mounting hole in a bogie frame; the spring set further comprises an adjusting pad used for adjusting the height of the spring set. The adjusting pad comprises a first composition part and a second composition part which can be separated from each other. The first component part and the second component part are respectively provided with a first notch and a second notch, and the first notch and the second notch form a center hole matched with the boss; the first component part and the second component part are respectively provided with a protrusion and a groove which are matched with each other, and the protrusion is provided with a head and a neck smaller than the head in size. The mounting operation of the adjusting pad can be simplified, the adjusting pad is prevented from being separated and disengaged, the mounting requirements of various rotating speed monitoring devices can be met, and the axle box is prevented from being disengaged from the bogie frame.
