THE NEED • Several Eaton customers (including OEM’s and dealers) have communicated a need for vibration analysis tools • Eaton Truck has great experience in vibration analysis technology and vibration complaint resolution • The Eaton DVA is leveraging these competencies, along with our diagnostic know-how and brand reputation, to bring these tools to market Truck Vibration Technology 3
DVA Driveline Vibration Analyzer The Eaton DVA is designed to: • Provide the ability to isolate fundamental vehicle vibrations • Using vehicle speed, pinpoint vibration problems that, in the past, have been difficult to diagnose. • Allow quicker diagnostics and repair of vibration complaints. Truck Vibration Technology 4
Driveline VIBRATION ANALYZER There are two versions of the DVA tool software; • Basic • Advanced The Basic version provides the set-up, testing, data collection, and reporting of information in an easy-to -use format. The Advanced version provides an engineering level view that allows for in-depth studying using vibration analysis tools on both live and saved data. Truck Vibration Technology 5
DVA BASIC VERSION • MSRP – $5, 175 • Target: Dealers, fleets and repair facilities • Benefits: – Increased diagnostic efficiency – Less vehicle down time – No part swapping Functions – Sensor input for signal verification – Chart With vibration criteria • Green Good • Red Bad – File saving and sending • Can be transferred to expert for analysis – Report printing Truck Vibration Technology 6
DVA ADVANCED VERSION • MSRP - $10, 000 Functions • Target: OEM’s and companies involved in the design of vehicles, suspensions, tires, wheels or driveline components • • Live spectrum view Cursors for common vibrations File collection for post analysis Post analysis of both linear and torsional vibrations • Analysis print-out for reporting • Benefits: – Powerful vehicle development tool – Improved ability to troubleshoot • End of line issues • Field complaints Truck Vibration Technology 7
