DRIVE WHEEL Meaning and
Definition
-
A drive wheel refers to a type of wheel that provides the necessary power and propulsion to move a vehicle or machine forward. It is an integral component of various vehicles and machinery, such as cars, trucks, motorcycles, tractors, and industrial equipment.
Typically located on a vehicle's rear axle, a drive wheel is responsible for transmitting torque or rotational force from the engine to the ground, enabling the vehicle to move. In most conventional vehicles, they are usually powered by internal combustion engines, where power is transferred from the engine to the drive wheels through a drivetrain system, which includes the transmission, differential, and axles.
The design and configuration of drive wheels can vary based on the type of vehicle and its purpose. In cars and motorcycles, for example, drive wheels are generally connected to the axle via wheel hubs, which contain bearings for smooth rotation. Alternatively, large trucks and industrial equipment often utilize drive wheels that are directly mounted onto the axle, delivering power more directly and with increased torque.
Drive wheels are typically manufactured with durable materials, such as steel or aluminum alloy, to withstand the rotational forces and various loads they encounter. Tread patterns on the outer surface of the drive wheels provide traction and grip, ensuring optimal performance in different terrain and weather conditions. The size and number of drive wheels can also vary depending on the specific requirements of the vehicle, with some vehicles featuring multiple drive wheels to enhance stability and power distribution.
Etymology of DRIVE WHEEL
The etymology of the word "drive wheel" is a combination of two separate components: "drive" and "wheel".
The term "drive" originated from the Old English word "drifan", which means "to push forward" or "to urge on". Over time, this word evolved to its modern form, retaining its meaning of impelling or propelling something forward.
The word "wheel" has its roots in the Old English word "hweol", which traces back to the Proto-Germanic word "hwehwlą". It refers to a circular object with a central axle, designed to rotate and facilitate movement.
When these two words are combined, the expression "drive wheel" can be understood as a wheel that provides the primary force or movement to propel a vehicle or machine. It is often connected to a source of power, such as an engine or motor, to enable motion.
