Model 3664 Shear Test Machine
The Model 3664 Shear Test Machine provides the means to evaluate the bond strength of friction material pad assemblies for passenger car, medium truck, and commercial vehicle disc brake pads.
This machine is designed to perform the SAE J840 Test Procedure. The machine consists of a two-axis loading frame with a high precision system for measuring displacement and load in the shear axis of a brake pad assembly as it is loaded along that axis. This is achieved using an air over oil hydraulic cylinder with an integrated magneto strictive displacement transducer and an in-line pancake load cell.
A normal load is applied such that friction force is minimized and does not significantly affect shear load.
A fixture is utilized to match the radius at lining contact. ProLINK software provides machine control and provides presentation of results, mean shear strength, and range.
