PURPOSE:To lower the height of a vehicle frame at time of traveling by attaching an axle of rear wheels to the central upper part of a symmetrical pair of plate springs being supported via a bracket extended to the lower side of a symmetrical pair of hollow side frames. CONSTITUTION:An axle of a symmetrical pair of rear wheels 2 is attached to each central upper part of a symmetrical pair of plate springs 6 supported on a hollow side frame 9 via brackets 12 and 13 extended to each lower side of a symmetrical pair of hollow side frames 9 at the front and rear ends. An extended value to the lower part from these hollow side frames 9 of the brackets 12 and 13 is set so as to secure a requisite minimum interval H sufficient enough to make the plate springs 6 fulfill its buffer function. Consequently, a distance between the underside of the hollow side frames 9 in a rear frame part 7b of an axle frame 7 and the upper side of the axle 4 can be set small, thus a ground clearance of the axle frame is made lower. |
