The Hofmann Brake Inertia Dynamometer is arranged ‘in-line’, with
the main elements being flywheel assemblies, brake test area, DC or AC
machine, and a disc brake.
Construction of the Brake Inertia Dynamometer
- A system of flywheels is mounted onto a common central shaft to simulate the mass of the test vehicle
- The minimum inertia is formed by the inertia of the shafts, couplings, and disc brake
- Variable inertia is obtained by engaging the appropriate flywheels
- Precise inertia simulation is obtained by ‘trimming’ using the - DC or AC machine
- The flywheels are engaged manually with a unique support and transfer system or automatically, using electromagnetic clutches
- A headstock is provided to mount the brake drum or disc
- A tailstock is supplied to support the brake shoe or calliper assembly and to transmit the reaction torque to a high precision load cell
- Speed is measured by an optical encoder and via a tachogenerator
- The tailstock traverses on tee-slotted rails for alignment with the brake drum or calliper
