SYSTEM FOR INCREASING TURN-RESTORING FORCE OF A STEERING VEHICLE WHEEL AND MOTION PERFORMANCE, RIDING COMFORT, AND COLLISION PERFORMANCE BY IMPROVING THE FREEDOM DEGREE OF A LAYOUT DESIGN

摘要

PURPOSE: A system for increasing turn-restoring force of a steering vehicle wheel is provided to control toe and accordingly to improve restoring force of a steering wheel by contracting the length of an out-turning driving shaft and extending an in-turning driven shaft. CONSTITUTION: In a driving system of a vehicle with a steering vehicle wheel suspension and a steering vehicle wheel thereof as a driving wheel, a turn-restoring force increasing system has a driving shaft moving unit(104) for contracting the length of an in-turning driving shaft and extending the length of an out-turning driving shaft by moving left and right driving shafts(202,204) for connecting left and right wheels(206,208) and a differential gear(200) according to steering degree in turning. The driving shaft moving unit is composed of guiders(226,228) fixed at each end of the differential gears of the left and right driving shafts not to disturb rotation of the driving shaft; a connection member(230) for coupling both guiders; and a moving mechanism disposed between the connection member and a vehicle body.
