Hybrid transmission

  • 29-Jun-2010 01:32 EDT


Currently in the evaluation phase, the TE-15HX concept transmission from Dana Holding is an electric parallel hybrid featuring a dual power path transmission control system designed for off-highway vehicles. Testing a configuration featuring a high-output, permanent magnet synchronous motor produces up to 63 hp (47 kW) and will improve the performance of the transmission when operational and allow the use of stored electric power during the duty cycle. Targeted for use in construction and material handling vehicles, the system monitors operating conditions and selects the proper combination of diesel and electric power to optimize productivity while reducing fuel consumption, emissions, noise, and engine idling. By positioning the electric device at the rear of the transmission to interact with drum speed, Dana can use a smaller unit that operates at a higher rpm and provides a better fit in the tight design envelopes of many off-highway vehicles.
