1. What is Side View Swing Arm Length?

Side View Swing Arm Length is the distance from the axis of the coil spring to the axis of the wheel in an independent suspension system. It plays a crucial role in determining the suspension geometry and vehicle handling characteristics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Percentage Front Braking — Proportion of braking force applied to the front wheels (%)
• Side View Swing Arm Height — Vertical distance from wheel center to upper pivot point (m)
• Height of CG above Road — Vertical distance from road surface to center of gravity (m)
• Wheelbase of Vehicle — Distance between front and rear wheel centers (m)
• Percentage Anti Dive Front — Angle at which suspension resists downward movement during braking (%)

Explanation: This formula calculates the optimal swing arm length based on vehicle geometry and braking characteristics to achieve proper anti-dive properties.

3. Importance of Side View Swing Arm Length Calculation

Details: Accurate calculation of side view swing arm length is essential for proper suspension design, ensuring optimal vehicle stability, handling, and braking performance while minimizing unwanted suspension movements.

4. Using the Calculator

Tips: Enter all values in appropriate units (meters for lengths, percentage for ratios). Ensure all values are positive and within reasonable ranges for vehicle parameters.

5. Frequently Asked Questions (FAQ)

Q1: Why is side view swing arm length important in suspension design?
A: It determines the suspension's kinematic properties, affects wheel camber changes during suspension travel, and influences the vehicle's anti-dive and anti-squat characteristics.

Q2: How does percentage front braking affect the calculation?
A: Higher percentage front braking increases the required swing arm length to maintain proper anti-dive characteristics during braking.

Q3: What is the typical range for side view swing arm length?
A: The length varies significantly based on vehicle type and suspension design, typically ranging from 0.3 to 1.2 meters for passenger vehicles.

Q4: How does center of gravity height affect the calculation?
A: Higher center of gravity requires longer swing arm length to achieve the same anti-dive effect, as it increases the braking torque around the wheel contact point.

Q5: Can this calculation be used for rear suspension as well?
A: While the formula is specifically for front suspension, similar principles apply to rear suspension design with appropriate adjustments for different load distributions and geometry.
