PRESSURIZING DEVICE OF REAR WHEEL FOR TRANSPORT VEHICLE

摘要

PURPOSE: A pressurizing device for a rear wheel of a transport vehicle is provided to disperse load of a loading portion transmitted to pressurize the rear wheel in entering a slope way to both rear wheel equally on the most effective position. CONSTITUTION: A pressurizing device for a rear wheel of a transport vehicle comprises driving apparatuses(10) and a support apparatus(20). Driving apparatuses are installed to right and left sides of an upper frame of the rear wheel. Lower ends of driving apparatuses are hinged to frames. The other end of the driving apparatus is slanted toward a central side of both frames. Upper ends of the driving apparatuses are hinged to right and left sides of the support apparatus to support a bottom of the tray in driving the driving apparatus. The support apparatus comprises a bracket(21) and a roller member(22). Thereby, damage of a driving device is minimized by dispersing load of the tray to the rear wheel of both sides and maintaining friction force of rear wheel equally.
