MM 245 AUTOMOTIVE GEAR SYSTEM, Manual Transmission, Computer interface

The apparatus is for studying the acceleration of an automotive gear system as well as gear system efficiency under different gear ratios and speeds.

The system uses a manual automotive gear. The input shaft is driven a motor dynamometer via a belt and pulleys. Speed is controlled by an inverter. The output shaft is attached to a water brake absorber dynamometer. The gear output shaft is extended for a study of inertia of a mass and equivalent inertia of the gear system. The dynamometer requires outside water supply.

The unit is on steel frame with adjustable footings.

Instruction manual is also included.

  • Input power, output power and efficiency.
  • Effect of speed and load on efficiency.
  • Equivalent inertia of the gear.
