The term scale describes the ratio of the drawing size relative to the actual size of the object. When you draw an object to scale, the drawing represents a ratio of the object size. With…
Gears are available in various shapes and sizes. Their application throughout the transportation industry varies greatly. When two (2) or more are used together as an assembly they are commonly referred to as a transmission (gearbox). The transmission’s primary task is to transmit motion, change the direction of the motion and/or change the rate of…
The modern vehicle is made up of a variety of parts and components all working together to achieve a final product: “The Car”. These parts and components are assembled in groups to perform various tasks. These groups are referred to as systems. There are many systems that make up the modern vehicle, some working with…
In a conventional manual transmission (gearbox) application there are two (2) gears involved (driven and Drive) for any given gear ratio. Each gear rotates on its own shaft. These gears can only offer two (2) variations between the input shaft and output shaft, forward or reverse but the ratio remains the same. With a planetary…
