Abstract

PURPOSE:To rationalize the parts around the rear footing by serving one suspension link as a tierod for steering the rear wheel while serving the trailing arm as a knuckle arm. CONSTITUTION:The outer end of a first lateral link 31 is coupled through a ball joint 34 to the front end section of the extended portion of a trailing arm 21 in front of a rubber bush associated with a pipe. While the outer ends of second and third lateral links 32, 33 are coupled through ball joints 35, 36 to the upper front and rear sections of the trailing arm 21. An axle 38 interlocked with the drive shaft 37 is born rotatably by a knuckle 25 while the rear wheel 39 is mounted on the axle 38 projecting to the outside of the knuckle 25.
