TORSION BEAM SUSPENSION

摘要

PROBLEM TO BE SOLVED: To reduce a road noise by suppressing the vibration of a torsion beam suspension on a vehicle running. SOLUTION: In the torsion beam suspension provided with a pair of trailing arms 1 arranged in a lengthwise direction of a vehicle, swingable vertically with setting a front end 10 to a vehicle body and rotable supporting a wheel at a rear end and a torsion beam 2 constructed between the both trailing arms 1 expanding in a vehicle-width direction between the both trailing arms 1 and combining the both ends at lengthwise middle position of the trailing arms 1, a dynamic damper 3 is formed to suppress the vibration of the front end 10 of the trailing arms 1 on the vehicle running.
