1. What is the Pivot Centre Calculation?

The Pivot Centre calculation determines the distance between the front wheel pivot centers based on vehicle track width, wheelbase, outside wheel lock angle, and turning radius of the outer rear wheel. This is essential for understanding vehicle steering geometry and turning characteristics.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ c = atw - 2 \times \left( -\frac{b}{\tan(\phi)} + Ror \right) \]

Where:

\( c \) — Distance between Front Wheel Pivot Center (m)
\( atw \) — Track Width of Vehicle (m)
\( b \) — Wheelbase of Vehicle (m)
\( \phi \) — Angle of Outside Wheel Lock (rad)
\( Ror \) — Turning Radius of Outer Rear Wheel (m)

Explanation: The formula calculates the distance between pivot centers by considering the vehicle's geometric properties during turning maneuvers.

3. Importance of Pivot Centre Calculation

Details: Accurate pivot center calculation is crucial for vehicle design, steering system optimization, and ensuring proper turning characteristics for safety and performance.

4. Using the Calculator

Tips: Enter track width, wheelbase, outside wheel lock angle (in radians), and turning radius of outer rear wheel. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is pivot center distance important in vehicle design?
A: It affects steering geometry, turning radius, and overall vehicle maneuverability and stability during cornering.

Q2: What units should be used for the angle input?
A: The angle should be entered in radians. Convert from degrees if necessary (degrees × π/180).

Q3: How does wheelbase affect pivot center distance?
A: Longer wheelbase typically requires different pivot center calculations to maintain optimal turning characteristics.

Q4: Are there limitations to this calculation?
A: This calculation assumes ideal conditions and may need adjustments for specific vehicle configurations or suspension designs.

Q5: Can this be used for all vehicle types?
A: While the formula is generally applicable, specific vehicle types may require additional considerations for accurate results.
