ABSTRACT:
There is provided an axle box suspension, having an axle spring, according to the present invention, wherein an axle box body is formed by providing an axle anchor rod at one end of the axle box, and the axle anchor rod is coupled to a truck frame through means of a resilient element, so that longitudinal, lateral and vertical swivel movements between the axle and the truck frame can be achieved by deforming the resilient element and the axle anchor rod without rattling therebetween, whereby the running stability of the vehicle is greatly improved. Furthermore, since the axle box suspension does not have relatively sliding components or gaps defined therebetween, wear and a deterioration due to years of operation are effectively reduced or eliminated, whereby replacement of the components will be obviated and maintenance thereof will be much more facilitated. Moreover, excellent advantages such as for example, simplified structure, space-saving with respect to the entire axle box suspension, and a reduction in its weight are achieved.
