Design and Implementation of Gearbox Test Rigfor Heavy Vehicles

Abstract

During repairing and troubleshooting gearboxes, a way to check and inspect its performance before and after repairs isneeded. However, while the engine tester (Dynamometers) are very generic and common and does not need to vary according to the engine manufacturer and model, the gearbox is very customized to the vehicle type, engine type, output required, and drive configuration. Therefore, there is a need to design a customized apparatus in order to accommodate the required procedures needed to complete the diagnostic of the gearbox performance.Customized gearbox testing devices may be imported but are very expensive; therefore, the need to design a device or apparatus for testing the gearboxes used in the working vehicles in the fleet of the company is raised.In this research, a simple, efficient gearbox performance testing apparatus for a specific vehicle gearbox. An A C motor to replace the engine was designed, implemented, and tested. It was found that using the apparatus increased the efficiency and the reliability of the gearbox maintenance shop.
