Abstract
The thickness of one of a pair of panels (an inner panel (20) and an outer panel (30)) of each trailing arm (12) is greater than the thickness of the other panel, and a rear wheel support unit (an axle unit (51)) configured to support each rear wheel is coupled to one of the pair of panels (the inner panel (20) and the outer panel (30)).
Claims18
An automobile rear suspension structure comprising:
- a suspension including a pair of right and left trailing arms extending in a vehicle longitudinal direction and each supporting right and left rear wheels and a torsion beam extending in a vehicle width direction and coupling both trailing arms,
- wherein each trailing arm includes a pair of panels having U-shaped sections and joined to each other in a state in which U-shaped openings face each other such that a sectional shape of the each trailing arm forms a closed sectional shape,
- a thickness of one of the panels is greater than a thickness of the other one of the panels,
- a rear wheel support unit configured to support each rear wheel is coupled to the one of the panels,
- the rear wheel support unit has a hub protruding outward in the vehicle width direction from a coupling portion where the rear wheel support unit and a corresponding one of the trailing arms are coupled together, and having a shaft portion located above the trailing arm, and
- each of the pair of panels has a shape such that a stiffness center in a section of a rear portion of each of the trailing arms is positioned closer to an outer top portion of a peripheral wall portion in the vehicle width direction.
