1. What is Wheel Torque?

Wheel torque is the rotational force applied to the wheels of a vehicle, calculated by multiplying the engine torque by the gear ratio. It determines the vehicle's acceleration and pulling power.

2. How Does the Calculator Work?

The calculator uses the wheel torque equation:

Where:

• \( T_{\text{wheel}} \) — Wheel torque (Nm)
• \( T_{\text{engine}} \) — Engine torque (Nm)
• \( \text{Gear Ratio} \) — Transmission gear ratio (dimensionless)

Explanation: The gear ratio amplifies the engine torque to provide greater rotational force at the wheels, improving vehicle performance.

3. Importance of Wheel Torque Calculation

Details: Calculating wheel torque is essential for understanding vehicle performance, optimizing gear ratios, and designing efficient powertrain systems.

4. Using the Calculator

Tips: Enter engine torque in Newton-meters (Nm) and gear ratio as a dimensionless value. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between engine torque and wheel torque?
A: Engine torque is the rotational force produced by the engine, while wheel torque is the amplified force at the wheels after accounting for gear ratios.

Q2: How does gear ratio affect wheel torque?
A: Higher gear ratios result in greater wheel torque, providing better acceleration and climbing ability, but may reduce top speed.

Q3: What are typical gear ratio values?
A: Gear ratios vary by vehicle and transmission type, typically ranging from 2:1 to 5:1 for lower gears in manual transmissions.

Q4: Does this calculation account for transmission losses?
A: This basic calculation assumes ideal conditions. Actual wheel torque may be slightly lower due to mechanical losses in the transmission system.

Q5: Can this formula be used for electric vehicles?
A: Yes, the same principle applies to electric vehicles, where motor torque is multiplied by the gear ratio to determine wheel torque.
