Steering gear for front/rear wheels

Abstract

Abstract PURPOSE:To main tain a symmetrical steering angle variation and the setting angle of a rear wheel in a highly accurate manner, by engaging an eccentric cam in a rear wheel stering system slidably with a joint member through a tapered engaging part, while performing automatic alignment by means of centripedal action. CONSTITUTION:An eccentric cam 32 is slidably engaged with a joint shaft 40 through a tapered engaging part 47, that is, a male taper member 36 is attached to the eccentric cam 32 via a ball 35, while symmetrical female taper members 43 and 43 are solidly attached to this joint shaft 40, whereby friction is reducible with such one fitted with rollers 46 interposingly between both tapers, and automatic alignment is performable with centripetal action of taper engagement. On top of that, the joint shaft 40 connectedly supporting tie rods 15 and 15 is shiftable horizontally in both directions, and since ball joints 14 and 14 are made impossible to move up and down, an error in stering angle variations at both sides is preventable from occurring and, what is more, the setting error of a rear-wheel steering angle is also preventable, thus performance check is as well formable in an easy manner.
