Steering

The Nascar dedicated front suspension uses the Recirulating Ball type steering. Recirulating Ball type steering is comprised of a Center Link that is rotated about a point on the chassis when the steering wheel is turned. Two Tie Rods are connected form the Center Link to the Upright.

 

To Edit the Steering Geometry;

 

1.     Select the Suspension Design Item that you want to edit the steering of.

 

2.     Click Summary to display the Input Summary Window.

 

3.     Scroll down to the Steering section.

 

4.     Enter Values

 

 

 

 

 

Tie Rods – Spindle

This is the point where the Tie Rod connects to the Spindle.

 

Tie Rods – Center Link

This is the point where the Tie Rod connects to the Center Link

 

Pitman Arm – Chassis

This is the point where the Pitman Arm connects to the Chassis

 

Pitman Arm – Axis

This point (along with the Pitman Arm – Chassis point) defines the axis that the Pitman Arm rotates around

 

Pitman Arm – Center Link

This is the point where the Pitman Arm connects to the Center Link

 

Idler Arm – Chassis

This is the point where the Idler Arm connects to the Chassis

 

Idler Arm – Center Link

This is the point where the Idler Arm connects to the Center Link

 

Steering Wheel Angle/Degree of Pitman Arm

This is the angular displacement of the steering wheel for one degree of pitman arm rotation.
