As the name suggests, the trailing arm is pivoted to the steering column at one side.
Spring and dampers are mounted between the trailing arm and the steering column with a fore
and aft arrangement. The wheel is mounted at the rear end of the trailing arm.

Model Use
The Single Side Trailing Link Suspension system can be used in front half vehicle or full
vehicle models of a two wheeler. The default geometry and mass approximate that of a two
wheeler scooter, but the model and data can be revised to reflect any size two wheeler.
Note:
The wheel body represents the mass and inertia of the tire and
the rim.
The wheel hub body represents the mass and inertia of other rotating bodies such as
a brake rotor. The wheel hub and brake rotor have no associated graphics.
The wheel and wheel hub parts use the Wheel center location as the center of
gravity.
The image below shows the Model Browser view of the systems on a fully
populated front suspension model. The Single Side Trailing Link Suspension system has two
“child” systems.
