In automatic transmissions a smooth clutch operation is related to the velocity dependence of the coefficient of friction (COF). Although JASO M348 and other full-scale clutch tests, or other ...

The functional lifetime of a wet clutch can be characterized using wear characteristics such as velocity dependence of the coefficient of friction (COF) and friction curves. Current market trends ...

In this webinar, we cover the motivation and method of a bench-top screening test for the friction characteristics of wet clutch materials and automatic transmission fluids (ATFs). A critical ...

Test service enhances Bal Seal offering for low-friction seals, verifies friction and leak rate for seals up to 22 in. diameter A new test service introduced by Bal Seal Engineering, Inc. offers ...

Spring technology for damping is relatively old. Stagecoaches had leaf springs, early trains had large, crude, coil-spring buffers (to absorb shocks when cars bumped together) and early automobiles ...
