Title:
AUXILIARY STEERING DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2014201164
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce wear of an auxiliary wheel in a case of performing an auxiliary steering while a part of a vehicle body is lifted.SOLUTION: An auxiliary steering device of a vehicle comprises: an auxiliary wheel 12 which is used to lift a vehicle body without driving force at the side of a third wheel different from right and left driving wheels; an auxiliary wheel lifting device which lifts up/down the auxiliary wheel 12 by using an auxiliary wheel support member; and a driving force difference adjusting device which can generate driving force difference between the right and left driving wheels when the auxiliary wheel 12 is grounded. A driving wheel, out of the right and left driving wheels, whose driving force generated by the driving force difference adjusting device is relatively small, is defined as a reference driving wheel. The auxiliary steering device of a vehicle includes a turning adjustment mechanism which can turn the auxiliary wheel 12 by a predetermined turning angle, when the auxiliary wheel lifting device lifts down the auxiliary wheel 12, or when the auxiliary wheel 12 rolls after being lifted down and grounded, so that a rotation axis S1 of the auxiliary wheel 12 turns toward the reference driving wheel side in a plan view.
