Coil Over Shock
Standard assembly of spring and damper, where spring perches are at each end of damper.
The image shows the CAD model of a coil over spring shock absorber arrangement.
The advantages of this type of arrangement are:
- they are compact
- the line of action of the spring and damping are coincident.
This means that they are easy to package and so create more space for articulation and steering or allow for a more vehicle package space.
The alignment gives the chassis designer a more clearly defined set of parameters.
