Profile-steel-type steering axle and machining technology

The invention relates to the field of axle assemblies and components thereof, in particular to a profile-steel-type steering axle. The profile-steel-type steering axle comprises an axle body, a steering oil cylinder, a connecting arm and a steering knuckle; the axle body comprises an axle body transverse beam, a supporting frame, a supporting shaft and a main pin sleeve, and the axle body transverse beam and the supporting frame are formed by integrally machining channel steel respectively. According to the technical scheme, the forklift steering axle which is high in structural strength and simple in forming process and a manufacturing process thereof solve the problems that in the prior art, the manufacturing process is cumbersome, the welding intensity is large, and the axle body is noteasy to maintain after being damaged; the profile steel is adopted as a main body of a rear axle, the axle body transverse beam and an axle body support are integrally formed, the welding seam lengthis reduced, the quality s
