ツイスト車軸懸架装置
Document Type and Number:
Japanese Patent JP4448504
Kind Code:
B2
Abstract:
A twist axle suspension for an automotive vehicle comprises first and second trailing arms, each having a front end and a rear end joined by an intermediate portion providing a weld site. The front ends of the trailing arms have pivots pivoted to the body of the automotive vehicle and the rear ends of the trailing arms support spring and damped rear wheels of the automotive vehicle. A perforated twist axle having first and second end sections abuts and is welded to the trailing arms at the weld sites. An arcuate apex portion joins the perforated walls to provide the twist axle with a V-shaped cross section having a shear center line disposed above the arcuate portion, the shear center being spaced a selected distance H above the axes about which the trailing arms pivot. A straight intermediate section of the twist axle is displaced from the first and second end sections to lower or raise the shear center line at the intermediate section without affecting the welds of the first and second end sections to the trailing arms.
