Model 1158 TO-4 Wet Friction Test Machine

Overview

The Model 1158 T0-4 Wet Friction Test Machine conducts tests for performance and durability of wet friction clutch plates, spacer plates and transmission fluids. This incremental inertia dynamometer uses the kinetic energy of the rotating mass that is absorbed by the reaction of a rotating friction disc and an opposing stationary steel plate. The operator can select test parameters and control modes, while displaying pertinent data and monitoring test data. The system uses the vehicle’s drive train lubricants as the cooling medium. Apply pressures are modulated to obtain controlled outputs in repetitive tests.
