1. What is the Wheelbase Calculation Formula?

The formula calculates the wheelbase of a vehicle using suspension geometry parameters and braking characteristics. It's derived from the relationship between anti-lift percentage, front braking percentage, swing arm geometry, and center of gravity height.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ b = \frac{\%ALr}{(\%Bf) \times \frac{SVSAh}{SVSAl} \div h} \]

Where:

\( b \) — Wheelbase of Vehicle (m)
\( \%ALr \) — Percentage Anti Lift (%)
\( \%Bf \) — Percentage Front Braking (%)
\( SVSAh \) — Side View Swing Arm Height (m)
\( SVSAl \) — Side View Swing Arm Length (m)
\( h \) — Height of CG above Road (m)

Explanation: The formula calculates wheelbase by considering how suspension geometry and weight distribution affect vehicle dynamics during braking.

3. Importance of Wheelbase Calculation

Details: Accurate wheelbase calculation is crucial for vehicle stability, handling characteristics, suspension design, and overall vehicle dynamics optimization.

4. Using the Calculator

Tips: Enter all values in appropriate units (meters for lengths, percentage for ratios). All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is Percentage Anti Lift?
A: Percentage Anti Lift is the percentage of weight transfer that is resisted by the suspension during acceleration or braking in an independent suspension system.

Q2: How is Percentage Front Braking determined?
A: Percentage Front Braking is the proportion of braking force applied to the front wheels, typically determined by brake bias settings and weight distribution.

Q3: What affects Side View Swing Arm geometry?
A: Suspension design, mounting points, and vehicle architecture determine the swing arm height and length parameters.

Q4: Why is Center of Gravity height important?
A: CG height affects weight transfer during braking/acceleration and significantly impacts vehicle stability and handling characteristics.

Q5: What are typical wheelbase values for different vehicles?
A: Wheelbase varies by vehicle type: compact cars (2.4-2.6m), sedans (2.7-2.9m), SUVs (2.8-3.1m), trucks (3.2-4.0m+).
