1. What is Percentage Anti Dive Front?

Percentage Anti Dive Front is the angle at which the suspension of a vehicle is designed to resist downward movement during hard braking. It represents the proportion of braking force that counteracts the vehicle's tendency to dive forward when braking.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: The formula calculates the percentage of anti-dive by considering the braking force distribution, suspension geometry, and vehicle center of gravity position.

3. Importance of Anti Dive Calculation

Details: Proper anti-dive calculation is crucial for vehicle stability during braking, preventing excessive front-end dive, maintaining tire contact with the road, and ensuring optimal braking performance and handling characteristics.

4. Using the Calculator

Tips: Enter all values in the specified units. Percentage Front Braking should be between 0-100%. All dimensional measurements should be positive values in meters.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical value for Percentage Anti Dive Front?
A: Typical values range from 20% to 50%, depending on vehicle type and suspension design. Higher values provide more resistance to front-end dive during braking.

Q2: How does anti-dive affect vehicle handling?
A: Proper anti-dive maintains vehicle stability during braking, prevents excessive weight transfer to the front, and helps maintain optimal tire contact with the road surface.

Q3: Can anti-dive be too high?
A: Yes, excessive anti-dive can make the suspension too stiff during braking, reducing ride comfort and potentially causing wheel hop or reduced traction.

Q4: How is Percentage Front Braking determined?
A: Percentage Front Braking is typically determined by the vehicle's brake bias system and represents the proportion of total braking force applied to the front wheels.

Q5: What factors influence Side View Swing Arm geometry?
A: Suspension design, mounting points, wheel travel, and desired handling characteristics all influence the Side View Swing Arm geometry in independent suspension systems.
