1. What is Wheel Torque Calculation?

Wheel torque calculation determines the torque delivered to the wheels based on engine torque and transmission ratios. This is essential for understanding vehicle performance, acceleration, and towing capacity.

2. How Does the Calculator Work?

The calculator uses the wheel torque formula:

Where:

• \( Wheel \) — Torque at the wheels (N·m)
• \( Engine \) — Engine torque output (N·m)
• \( Ratios \) — Combined transmission and differential ratios (unitless)

Explanation: The transmission and differential multiply engine torque to deliver higher torque to the wheels, improving vehicle performance.

3. Importance of Wheel Torque Calculation

Details: Calculating wheel torque is crucial for vehicle design, performance tuning, towing capacity assessment, and understanding acceleration characteristics.

4. Using the Calculator

Tips: Enter engine torque in N·m and transmission ratios as a unitless value. All values must be valid (engine torque > 0, ratios > 0).

5. Frequently Asked Questions (FAQ)

Q1: What factors affect wheel torque?
A: Gear ratios, final drive ratio, tire size, and transmission efficiency all impact the final wheel torque.

Q2: How does wheel torque relate to acceleration?
A: Higher wheel torque generally results in better acceleration, though vehicle weight and aerodynamics also play significant roles.

Q3: Why is wheel torque higher than engine torque?
A: Transmission and differential gears multiply the engine torque, resulting in higher torque at the wheels.

Q4: How do different gears affect wheel torque?
A: Lower gears (1st, 2nd) provide higher torque multiplication, while higher gears provide less multiplication but higher speed.

Q5: Does this calculation account for transmission losses?
A: This basic calculation assumes 100% efficiency. Real-world applications should factor in typical transmission losses of 10-15%.
