Clutch and brake systems put to the test

Safety that stands the test of time

From precise control to emergency stops: clutch and brake systems must work perfectly in every situation. Our tests combine mechanical, thermal and hydraulic tests to ensure long-term performance and safety.

Focus on comfort and reliability

Function that convinces

Separate, connect, decelerate - clutch and brake systems are crucial for control and driving feel. PTS-Prüftechnik develops tailor-made test set-ups, analyzes friction behavior, evaluates seals and simulates real load curves. Whether it's a wear test or series approval: we deliver reproducible results for your safe decision.

Realistic load. Precise evaluation.

Our test setups measure the frictional contact precisely - for reliable statements on function, service life and quality.

Scope of services:

CFD-supported test box design
Shifting & braking cycles with real friction partners
Endurance & wear tests
Online monitoring with O.K./N.K. evaluation
EOL acceptance tests with series reference

Test your systems under real friction conditions - reproducible and automated.

From coefficient of friction to releaseOurtribological tests are seamlessly linked to the test: We analyze microstructures, check dimensional accuracy and evaluate thermal or mechanical damage - documented in a traceable manner.

Analysis methods:

Microscopic structural comparisons and material analyses
Dimensional inspection of lamellas and linings
Assignment to O.K./N.K. criteria for series approval

Recognize wear limits at an early stage - for reliable approvals and reduced development cycles.
