The invention relates to a bogie primary suspension device for a railway vehicle, in particular to a primary suspension fixed between an axle box and a framework through rubber springs. According to the bogie primary suspension device, the appearance of the rubber springs adapt to the outer surface of a shell of an axle box body, so that the rubber springs are attached to the outer surface of theaxle box body, the occupied space is reduced, and meanwhile the damping contact surface is increased.
