FOUR-WHEEL DRIVEN MULTIPURPOSE ROAD MANAGEMENT VEHICLE EQUIPPED WITH A DYNAMIC DAMPER WHICH ABSORBS THE VIBRATION TRANSMITTED THROUGH A FRONT AND A REAR DRIVE SHAFT

摘要

PURPOSE: A four-wheel driven multipurpose road management vehicle is provided to improve balance of damping oscillation frequency by using a pair of dampers and to set the damping oscillation frequency variably by controlling the weight of a weight member.;CONSTITUTION: A four-wheel driven multipurpose road management vehicle comprises an engine, a transmission(30), front and rear drive shafts(35,36) which are arranged at different alignment angles and receive power through a main axle(31), a transfer case(40) which selectively transfers the power to the front and the rear drive shaft, a fastening member, and a dynamic damper(60) which absorbs the vibration of the transfer case and the vibration transmitted through the front and the rear drive shaft. The fastening member includes a weight member which is composed of a pair of weight units coupled by a first joint, an elastic bushing which covers the contact face of the weight units, and an elastic member which is deformed freely within a groove formed by the coupled weight units.;COPYRIGHT KIPO 2010
