Engine and drivetrain of a transverse-engined front-wheel drive car. 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.
drivetrain. Also drive line. All of the components of a motor vehicle that are involved in delivering power to the drive wheels, excluding the engine or motor that generates the power. The drivetrain typically includes the clutch (if present), transmission, drive shaft, differential, and one or more axles. Contrast powertrain. drop arm See ...
* Drivetrain:The drivetrain is the system that connects the transmission to the wheels, distributing power as needed. It includes key components such as the driveshaft, which transfers rotational power, the differential, which allows the wheels to rotate at different speeds for smoother cornering, and the axles, which deliver power directly to ...
An ICE sized for average power use charges the accumulator. The accumulator is sized to run the car for 15 minutes when fully charged. [67] [68] [69] In January 2011, Chrysler announced a partnership with the EPA to design and develop an experimental gasoline-hydraulic hybrid powertrain suitable for use in passenger cars.
For liquid-cooled vehicles, however, this layout presents a disadvantage, since it requires either increased coolant piping from a front-mounted radiator (meaning more weight and complexity), or relocating the radiator(s) to the sides or rear, and adding air ducting to compensate for the lower airflow at the rear of the car.
The powertrain layout of a motorised vehicle such as a car is often defined by the location of the engine or motors and the drive wheels. Layouts can roughly be divided into three categories: front-wheel drive (FWD), rear-wheel drive (RWD) and four-wheel drive (4WD). Many different combinations of engine location and driven wheels are found in ...
Eight-wheel drive, often notated as 8WD or 8×8, is a drivetrain configuration that allows all eight wheels of an eight-wheeled vehicle to be drive wheels simultaneously. Unlike four-wheel drive drivetrains, the configuration is largely confined to heavy-duty off-road and military vehicles, such as armored vehicles , tractor units or all ...
The system consists of a longitudinally mounted boxer engine coupled to a symmetrical drivetrain with equal length half-axles. The combination of the symmetrical layout with a flat engine and a transmission balanced over the front axle provides optimum weight distribution with low center of gravity , improving the steering characteristics of ...
