Brake-Drum Friction Apparatus- Engineering Lab Training Systems

CAT NO: DIDACTICNLE-Export-059009

Description & Specification:

Brake-Drum Friction Apparatus- Engineering Lab Training Systems.
Features Low-cost effective teaching Self-contained Bench mounted Particularly suitable for motor vehicle teaching Comparison of leading and trailing shoes Determination of coefficient of friction Simulates real brake drum Three year warranty Range of Experiments To determine experimentally the variation of tangential force with braking load To obtain the coefficient of friction between the aluminium drum and the brake shoe To compare leading and trailing shoes Description An aluminium brake drum has a torque applied to it by a loaded weight hanger. The sense of rotation of the torque determines whether the single brake shoe acts as a leading or trailing shoe. A braking load is applied through a second loaded hanger. Direct comparison of tangential force and braking load is obtained and the coefficient of friction determined. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results.
