Measuring Wheel Forces and Torques
Determining wheel force and wheel torque is essential for the development of modern vehicles. One common way of measuring drive torque is via strain gauges on the original output shaft. Another equivalent method is measurement via an explicit torque sensor, which is fitted between the rim flange and the wheel hub. Choosing the best measurement technique is determined by what you are trying to learn from the measurement. As with torque, structural parts of the vehicle, such as chassis parts, can also be equipped with strain gauges for force measurement. However, if you want to measure forces and torques combined with high precision, you must use a Wheel Force and Torque Transducer. This measures the three forces on each wheel in the Fx, Fy and Fz directions as well as the corresponding torques between the wheel hub and rim.
Here is a summary of when and why you collect this data:
1. Vehicle Dynamics Analysis
Wheel force transducers provide data for analyzing vehicle stability and handling.
2. Vehicle Performance Testing
Torque wheels measure wheel torque, crucial for assessing powertrain and drivetrain efficiency.
3. Automotive R&D
Torque wheels gather data on wheel forces under various conditions, aiding in vehicle design for enhanced safety and performance.
4. Road Load Date Acquisition
Wheel force transducers measure loads during acceleration, braking, and cornering, informing chassis and suspension design.
5. Tire Testing
They measure forces and torques on tires, crucial for developing improved grip and durability.
6. Road Surface Analysis
Wheel force transducers analyze how different road surfaces affect wheel forces, guiding road design and vehicle performance optimization.
These diverse applications highlight the importance of wheel force and torque transducers in the automotive field, underscoring their essential role in vehicle design, testing, and performance analysis.
