Free Wheel Hubs
LAMDA FREE WHEEL HUBS
A 4WD vehicle need not operate as a 4WD in all cases. When a 4WD vehicle is out of a terrain where a 4WD is required, unnecessary fuel consumption and load is applied on the engine. In order to convert a 4WD vehicle to 2WD vehicle and get all the benefits of a 2WD vehicle, free wheel hubs are used. Locking hubs, also known as freewheeling hubs are fitted to four wheel drive vehicles, allowing the front wheels to rotate freely when disconnected (unlocked) from the front axle. This is done to reduce the mechanical resistance of the front-portion of the drivetrain when four-wheel drive is not in use. The hub, along with the wheel, is designed to engage (lock) onto the axle, to be powered by the drivetrain in four-wheel drive; or the hub can disengage (unlock) from the axle when four-wheel drive is not needed, thus allowing the front wheels to rotate freely within the hub. The hub is a component where the wheel is directly mounted to, and is outside the axle.
Mechanically activated locking hubs are activated by hand by turning a switch on the end of the axle.
The advantage to mechanical hubs is that they are often considered more robust, and less prone to issues due to maintenance negligence. The disadvantage of this is that the driver needs to get out of the vehicle to activate the hubs.
