ABSTRACT:
In a dynamometer, an internally cooled disc is utilized in a braking system which can apply a large amount of torque for an extended period of time. A hollowed braking disc comprising individual cooling cells is employed. Cooling liquid is injected into the center of the braking disc and, by centrifugal force, is forced into the cooling cells via a flow tube ring. The cooling liquid vaporizes in the cooling cells thus absorbing the heat generated. The vapor escapes the disc via vent holes. A unique torque measurement system is also utilized with its braking system. A resultant force, formed by the sum of individual forces upon braking pistons within the braking system, is measured utilizing a strain gauged load cell. The strain gauged load cell is strategically positioned to measure a resultant displacement of the braking caliper due to the applied torque.
