Flywheel brake dynamometer

A reliable braking system has always stood for driving safety. Flywheel brake dynamometers from RENK are designed for the optimization of existing brake systems and development of settings for future rail vehicles.

The type of braking system, and the way braking pressure is generated are adapted to the specific project. A key design characteristic of RENK brake dynamometers are the automatically switchable flywheel masses, which are used as standard. Controlled by test stand automation, this makes it possible to modify the simulated vehicle weight anywhere in the adjustment range without manual intervention even during a test run.

Flywheel brake dynamometers from RENK fulfill all the requirements for certifying them for the development of brake systems and their components with current test standards by means of easy handling.
