A drivetrain (also frequently spelled as drive train or sometimes drive-train) or transmission system, is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. [1]
General Motors, BMW, and DaimlerChrysler collaborated on a system named "Two-Mode Hybrid" as part of the Global Hybrid Cooperation. The technology was released in the fall of 2007 on the Chevrolet Tahoe Hybrid. The system was also featured on the GMC Graphite SUV concept vehicle at the 2005 North American International Auto Show in Detroit. [32]
Drivetrain Systems International was formed following the purchase of the Lavington gearbox factory, built in 1971, from the ION Group in 2004. In 2007, the factory produced gearboxes for SsangYong , which became the DSI's largest customer following the cessation of Ford 's patronage in 2011.
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios .
A 6×4 or six-by-four is a vehicle with three axles, with a drivetrain delivering power to two wheel ends on two of them. It is a form of four-wheel drive but not one of all-wheel drive. Classic Truck twin rear axles providing drive via 8 wheels: 6x6 6X6, a standard class of medium-duty trucks Classic Mil spec: 6x6 drive train power to rear and ...
The acquisition helped establish the newly formed Magna Drivetrain group as a major supplier of four-wheel and all-wheel drive systems manufactured in Europe and North America. [4] Tesma was privatized again by Magna in December 2004. [5] [6] In 2005, Magna merged Magna Drivetrain with Tesma to form Magna Powertrain. [7]
The system allows optimum timing of intake valve operation. MultiAir technology can increase power (up to 10%) and torque (up to 15%), as well as reduce consumption levels (up to 10%) and emissions of CO 2 (up to 10%), particulates (up to 40%) and NOx (up to 60%) [ 3 ] [ 7 ] when compared to a traditional petrol engine.
Most chain drive systems use teeth to transfer motion between the chain and the rollers. This results in lower frictional losses than belt drive systems, which often rely on friction to transfer motion. Although chains can be made stronger than belts, their greater mass increases drive train inertia.
