MOUNTING STRUCTURE OF TOWING APPARATUS FOR A VEHICLE, CAPABLE OF IMPROVING THE STRENGTH OF ASSEMBLY PERFORMANCE AND RIGIDITY OF A SHAFT WHICH IS INSTALLED IN THE FRONT AND REAR THROUGH-HOLES

摘要

PURPOSE: A mounting structure of towing apparatus for a vehicle is provided to improve the machining accuracy of the rear through-hole by independently using the front through-hole for the entry of a punch for forming the rear through-hole.;CONSTITUTION: A mounting structure of towing apparatus for a vehicle comprises a beam(100), a shaft(200), and an eye bolt. One side of the beam is equipped in a front or rear side of a vehicle. A front circular through-hole is formed on the front surface of the beam. The rear side of the beam facing the front circular through-hole is equipped with a rear circular through-hole with smaller diameter than the front circular through-hole. The shaft is combined with the beam and protruded at regular intervals between the front through-hole and the rear through-hole. The center of the shaft forms the eye bolt combining hole(220). The rear side of the eye bolt combining hole is equipped with a spiral combining unit. One end of the eye bolt forms a connecting hole for combining with an external towing device. The other end is equipped with a spiral unit to be hung and fixed to the spiral combining unit of the shaft.;COPYRIGHT KIPO 2013
