Master Thesis - Benefits of active lubrication in modern transmissions
Background
The oil system has become a very important function in modern transmissions. It lubricates gears, bearings, clutch systems and electric motors. It acts as a hydraulic media for clutch and gear actuation and it also transport heat away from the gearbox. The amount and distribution of oil plays an important role for transmission efficiency. Focus must be set to minimize drag torque losses at the same time as high torque puts large demands on lubrication properties.
The Powertrain Hardware Design, Clutch, Shifting and Oil System team is responsible for research and development of new technology transmissions with high efficiency. Low emission and fuel economy is one of the biggest driver for transmission development today. That is why it is very important to understand the benefits and use active lubrication in best possible way.
Scope
The aim of this thesis project is to understand and quantify efficiency improvements by using different grades of active lubrication in the transmission. Study what is available on the market today, new upcoming technologies and adapt to CEVT development projects. Use and refine existing simulation models by experimental test work, within the possible existing capabilities. Take into consideration electric consumption to operate the system and weight the increased system cost and complexity to conclude on the efficiency gain for the complete vehicle.
