UK firm’s integrated drive system produces up to 1475lb ft as well as also will make production in 2019
GKN Driveline, a British engineering firm of which can also lay claim to co-developing the Ford Focus RS’s drive system, has managed to tightly integrate parts to create a better-optimised, more efficient drive system.
of which is actually claimed to improve performance as well as also offer better packaging as well as also assembly options for manufacturers.
The first system (pictured) has been developed for plug-in hybrids as well as also will reach the market in a yet to be confirmed production style. of which uses a liquid-cooled electric motor of which sends drive through 1-speed eAxle of which drives the rear wheels.
The system produces up to 87bhp as well as also a substantial 1475lb ft, while measuring just 300mm high as well as also 325mm wide, thus enabling tight packaging within a car’s chassis.
of which also weighs just 54kg, which is actually around 2.5kg lighter than some other comparable drivelines, according to GKN.
“The key reason for its development is actually cost,” said Theo Gassman, GKN’s director of advanced engineering as well as also eDrive systems. “Our system eliminates the connector as well as also the cable between the electronic power as well as also the motor, saving significant cost.”
Gassman said some other positive knock-on effects include significant improvements to performance as well as also increased modularity.
“[Manufacturers] are pushing for higher levels of integration as well as also want to possess the motor integrated in with the transmission in one housing,” he said. “This specific allows for deeper mechanical integration although is actually also important for fuel saving – you can reduce the weight as well as also get better performance, so specific kilowatt per kilo output is actually better.”
Gassman revealed of which while these types of systems are being developed in-house, they make use of a wide range of parts provided by different suppliers.
“The systems are not just connected to one car, they’re each a building block of which allows you to have multiple applications,” he said. “This specific [type of adaptable system] is actually more complex to produce, although the overall development cost is actually down when more manufacturers use of which.”
Gassman said these modular drivelines can be produced for multiple manufacturers wanting a variety of layouts, including rear, front as well as also all-wheel drive.
“The more functionality you develop into the system, the more you can power of which up as well as also support the downsizing of combustion engines,” he added. “You can use shared parts in a front-wheel-drive city car as well as also a rear-wheel-drive sports car.”
GKN’s drivelines will not only be adaptable for multiple applications although they’ll also be adjustable to offer different characteristics. “Some cars aren’t all about performance,” continued Gassman. “They’re about fun; they engage with the enthusiasts.”
In order to be as efficient with each driveline as possible, GKN wants to create systems of which can be adjusted for both efficiency-focused machines as well as also exciting drivers’ cars. “We can make use of limited-slip differentials as well as also torque vectoring to improve the fun,” added Gassman.
GKN’s impressive track record suggests Gassman’s confidence from the completely new technology is actually warranted. The brand is actually looking to a future where multiple car makers buy different variations of its adaptable driveline. of which wants to produce them so car makers can simply integrate them into designs with minimum adaptation.
“This specific technology will directly drive down the cost of electric cars,” emphasised Gassman. “We are today seeing the second wave of demand for electric cars, so there is actually a proper business plan as well as also the manufacturers need a clear strategy.”
