Definitions:

Suspension

Means by which axles are attached to the vehicle frame; supports the frame and dampens it from road shock using springs (leaf, air, torsion, rubber, etc).

Landing Gear

The retractable legs used to support a semi-trailer when not coupled to a tractor; most have gear-actuated, retractable legs but hydraulic and lock-pin systems are also available.

Rigid Double-Drawbar System

A specific hitching setup in towing configurations where two drawbars are used in a rigid manner to link a truck and a trailer or between trailers.

Pivot Points

Locations on a vehicle or machinery where parts pivot or rotate around a fixed point, crucial for the movement or operation of certain components.
