As an AI language model, I assume you meant "bogie wheel" instead of "boggie wheel". Here's some information about bogie wheel:

A bogie wheel, also known as a bogie truck, is a type of wheel arrangement commonly used in railway vehicles. It consists of a pivotable frame that carries a set of wheels and is attached to the body of the vehicle through a bearing. Bogies provide stability to the vehicle, especially when navigating curves and uneven track surfaces.

Bogie wheels come in various designs and sizes, depending on the intended use and load capacity of the railway vehicle. They are typically made of steel or cast iron and are designed to withstand heavy loads and wear and tear.

In addition to railways, bogie wheels are also used in some types of heavy vehicles, such as trucks, buses, and military vehicles. They provide improved stability and load-carrying capacity, as well as better maneuverability and ride comfort.
