Tire endurance test stand from TMX Solutions

On the road, tires face many different loads for months or years: high speeds, changing loads and thermal stress. To test tire service life efficiently and repeatably, the TMX endurance test stand simulates these conditions in a fraction of the time.

TMX test stands create realistic load scenarios with high precision, a key development tool for tire manufacturers, test service providers and automotive OEMs. Weak points show up during development, and validation can start early.

Typical test requirements

• Testing of overall service life and durability of a tire
• Simulation of overload situations (e.g. loaded vehicles, trailer operation)
• Analysis of abrasion and wear behavior
• Continuous load with realistic load changes
• Testing at speeds above the tire's rating
• Tread wear tests on different surfaces

The TMX solution: the tire test stand in detail

TMX tire endurance test stands typically use a modular design with drum drive and load carriage and adapt flexibly to customer requirements. Depending on the concept, up to six tires can be tested in parallel: efficient, space-saving and under identical test conditions.

Test stand mechanics

• Drum simulates the road, accelerated by a controlled main drive
• Carriage system with spindle actuator for precise wheel load
• Mechanics designed for long test times and high thermal and mechanical stress
• Configurable as needed:
  • Drum loaded on one or both sides
  • Multiple test stations with up to six devices under test (identical speed profile)
  • Optional steering and camber angle adjustment

Drive and control

• Frequency inverter for the main drum drive
• Servo motors and gear spindles for wheel load and, where needed, steering and camber angle
• Optional multiple drums with separate control for different profiles

Measurement and control technology

• High-accuracy measurement of:
  • wheel load
  • tire temperature
  • drum speed
  • steering and camber angle (optional)
• Distributed measurement system for all channels
• Automatic detection of and response to limit violations
• Expandable with sensors for tread depth, impact or imbalance

Operating software

• TMX test sequence editor for simple configuration of the test sequence
• Guided operation with status displays and live data
• Automatic result reports
• User-friendly, safe and low-maintenance

Summary

The TMX tire endurance test stand is a powerful platform for repeatable service life testing of tires. Modular design, rugged mechanics and intuitive software make it a good fit for research, development and quality assurance, in the lab and in continuous operation.
