Automatic transmission fluid anti-shudder friction tester for vehicle testing
Whats/App: +86 156 1874 6768
Web: standard-groups.com
Standards
The tester is designed to meet and support the following domestic and international standards and test methods:
(1) GB/T 11118 — Tribological Performance Test Methods for Lubricants
(2) GB/T 3142 — General Test Methods for Lubricant Viscosity and Performance
(3) JASO M348 — Friction Characteristics Test Method for Automatic Transmission Fluids
(4) SAE No.2 — Friction Test Method for Automatic Transmission Fluids
Note: Differences in speed profiles, loading modes, temperature programs, and data processing requirements among standards can be accommodated through software parameter configuration.

Features
(1) Servo-hydraulic constant-force loading ensures high stability and fast response of axial load
(2) AC servo drive system meets strict accuracy requirements for low-speed friction testing
(3) Supports both LVFA low-speed friction tests and SAE No.2 durability test modes
(4) High-precision strain-gauge sensors simultaneously measure load and friction torque
(5) Integrated heating and cooling temperature control system enables wide temperature testing
(6) Integrated control and data acquisition system provides fully automated test operation
(7) Built-in μ–V curve analysis and anti-shudder life evaluation logic reduces operator influence
Accessories
(1) Friction plate fixture for standard friction plate sizes
(2) Steel plate fixture compliant with JASO and SAE requirements
(3) Servo-hydraulic axial loading unit
(4) Temperature-controlled oil bath with heating and cooling
(5) Industrial all-in-one computer with control and analysis software
(6) Sealing components for routine replacement
(7) Operation manual
Test Procedures
(1) Install the friction plate and steel plate with proper coaxial alignment
(2) Fill the test chamber with the specified volume of transmission fluid
(3) Perform the running-in stage according to the selected standard
(4) Execute μ–V characteristic tests using defined speed steps
(5) Conduct durability cycling tests to monitor friction coefficient evolution
(6) Stop the test automatically upon completion of the programmed cycle
(7) Remove samples and inspect wear condition
(8) Generate test curves and reports using the software system
Maintenance Information
(1) Check fixture alignment before each test to prevent eccentric loading
(2) Set running-in and test parameters strictly according to the applicable standard
(3) Do not exceed the specified axial load and temperature limits
(4) Allow natural cooling after high-temperature tests before disassembly
(5) Regularly calibrate load, speed, and temperature sensors
(6) Replace sealing components periodically to ensure system reliability
