The present invention relates to a novel structure of a steering joint of an axle beam, capable of supporting an auxiliary wheel coupled to an axle beam in a direction adjustable manner. According to the present invention, an axle beam (10) has a pipe shape with both ends opened, and extended in a lateral direction. The steering joint is formed with a projected portion (21) to be engaged to both ends of the axle beam (10), and an engagement hole (31) extended in a vertical direction to be engaged by a kingpin, to be coupled and fixated on both ends of the axle beam (10). A knuckle engaged with the auxiliary wheel is able to be connected to the kingpin engaged to the engagement hole (31) in a direction adjustable manner. As such, the present invention allows to integrate the auxiliary wheel in a direction adjustable manner on both ends of a conventional axle beam (10), with an advantage of reducing manufacturing cost and easily producing to a desired shape. |
