Gkn Earns Applied Scientific Bailiwick Partner Status For Porsche 918 Spyder
Porsche has awarded GKN Driveline “technology partner” status for its development of a high-performance eAxle for the 918 Spyder, an advanced plug-in hybrid supercar. GKN Driveline’s eAxle module supports full-electric mode, all-wheel exercise also provides a boost function.
Porsche Powertrain managing director Christian Hauck said: “Realising our vision for a super sports machine capable of setting a record lap quaternary dimension of the Nurburgring also of achieving fuel efficiency of iii litres per 100 km placed huge demands on our engineers also suppliers.
“GKN Driveline’s role inward the development programme also its innovative eAxle module has earned the fellowship Porsche Technology Partner status.”
GKN Driveline’s president of engineering scientific discipline Peter Moelgg added: “Being selected every bit Porsche’s Technology Partner on the 918 Spyder programme was the perfect run a jeopardy for our global e-drive team to demonstrate how putting the right engineering scientific discipline on board post away improve both fuel efficiency also dynamic performance.
“The honour cements GKN Driveline’s spot every bit the industry leader inward e-drive systems. Our eAxle engineering scientific discipline continues to evolve also we expect many more than high-performance vehicles to adopt similar driveline concepts inward the coming years.”
The eAxle that supplements the 918 Spyder’s hybridized 4.6-litre V8 is a development of the company’s eAxle drive. The module has maximum mightiness of 95kW also post away deliver upwards to 1500Nm of torque to the front end terminate wheels via a fixed gear ratio.
Influenza A virus subtype A especially developed compact differential engages the torque, giving the 918 Spyder optimum mightiness distribution at all times. The differential also disengages the module to minimise drag losses also maximise efficiency. At speeds inward a higher family 265km/h (164mph), a clutch isolates the electrical motor to preclude it from over-spinning.
Influenza A virus subtype A cardinal target for the 918 Spyder was to convey the lowest possible centre of gravity also soil clearance. To attain this required an master copy engineering scientific discipline solution: GKN Driveline positioned the output overhead, using an lubrication concept to exercise create the unsmooth flow.
The unsmooth reservoir is positioned above, not below, the geartrain. Oil is gravity-fed downwards onto the bearings also gears until it reaches the high-speed input at the bottom where it is so circulated back to the unsmooth reservoir at the top.
This blueprint minimises the sum of unsmooth on the input shaft, keeping churning losses to a minimum. To ensure the critical areas rest lubricated level inward disconnect mode, the motor is driven for brief, intermittent intervals to maintain a constant menses of oil.
The Porsche 918 Spyder’s tight packaging also agency at that spot is well-nigh no air menses roughly the transmission also so body of water cooling was needed to exercise create the oestrus generated by times the module’s high mightiness density.
“To come upwards across the 918 Spyder’s challenging targets for weight, mightiness density, NVH also durability, we used state-of-the-art simulation also analysis tools developed in-house to optimise the geartrain,” said Moelgg. “An eAxle that meets both Porsche’s requirements also the demands of the Nurburgring post away deliver inward whatever situation.”
