Frame – Ladder - Rigid

The frame or the chassis is the main structure over which all other systems are attached or connected. For a heavy truck, the frame consists of a ladder structure spanning the length of the truck.
Figure 1.


The Frame system consists of a Chassis body that is rigid with a Ladder frame graphics as shown above. The chassis body has two joints (an Inline and a Perpendicular joint) that hold the vehicle during static simulation in any full vehicle event.

Cabin

Conventional/Semi-forward Cab
The full truck model comes with a Conventional/Semi-forward cabin system that contains a rigid cabin body with graphics.

Cabin Suspension

There are two options available to attach the cabin with the frame while assembling the Full truck model.
Figure 3.


  1. Fixed to Chassis – The cabin is fixed to the Chassis body using a fixed joint.
  2. Rear coil spring with dampers – In this configuration, the cabin is pivoted by a pair of bushings in the front and latched to the chassis at the rear using a pair of coil-spring and dampers (shocks).
