Title:
TANDEM AXLE SUSPENSION DEVICE
Document Type and Number:
Japanese Patent JP2007030670
Kind Code:
A
Abstract:

To provide a tandem axle suspension device which can adjust the axle weight distribution acting on a driving shaft and a driven shaft only by changing a laminated elastic body without changing the related parts, improve traveling performance of the vehicle, and enhance versatility.

A spring constant in the vertical direction of the laminated elastic body 7 of the side corresponding to the driving shaft 9 is set to a value higher than the spring constant in the vertical direction of the laminated elastic body 7 of the side (rear side) corresponding to the driven shaft 11, and the spring constant in the horizontal direction of the laminated elastic body 7 of the side corresponding to the driving shaft 9 is set to a value approximately equal to the spring constant in the horizontal direction of the laminated elastic body 7 of the side corresponding to the driven shaft 11, and the axle weight control for the driving shaft 9 and the driven shaft 11 is performed by changing the inclination angle θ1 and the number of lamination of an elastic member 5 and a plate 6 in the laminated elastic body 7 of the side (front side) corresponding to the driving shaft 9 while keeping the inclination angle θ0 and the total length H of both mounting surfaces.
