<p>PURPOSE: A rear suspension is provided to disperse the stress concentrated on a coupling part and improve the strength of the coupling part because an extension part of a torsion beam is surface-connected to a trailing arm. CONSTITUTION: A rear suspension(100) comprises a torsion beam(110), an extension part(120), a trailing arm(130), and a reinforcement part(140). The extension part is extended from an end of the torsion beam. The trailing arm is coupled to the extension part via surfaces and welded together. The reinforcement part is coupled to surround the extension part and the trailing arm and welded together.</p> |
