What are the benefits of using a gearbox in electric vehicles?

Started Mar. 29, 2023

Abstract or project description

Gearboxes are common components found in gas-powered vehicles, but not so much in electric vehicles. Gearboxes can provide electric vehicles with numerous benefits like increased range, less strain on EV motors, and increased speed and efficiency. There are various different kinds of gearbox configurations with discrete or continuous gears of different numbers and ratios. While gas-powered cars only have one gearbox connected to their single-engine, EVs can have one or more gearboxes connected to their multiple motors in different setups. In this research paper, we will calculate how different gearbox designs affect electric vehicle dynamics, by using equations, graphs, and analysis.

Abstract or project description

Engineering systems in modern cars have become so complex that collecting and understanding information about them is exceedingly difficult. This research website, Learn Your Car, will eliminate search time by providing concise information in one convenient location. A modern car consists of three sections that are thoroughly engineered; the powertrain, chassis, and bodywork elements. Although modern cars' layouts and engineered components differ in numerous ways, they all share common characteristics with one another(like same structure for engine, transmission, electric motor type, and more). The website is structured in a way that connects all these different engineered systems, and unites them into a common layout. For example, a user navigating this website may see that there are three different types of hybrid powertrains available, but their components like electric motors and batteries, are all composed of similar features. Using this approach, the user can interact with the various configurations of a modern car's layout, while understanding the essentials of each component and how they all form a common linkage with one other. From a single Google search, a reader can use this website to gain a deeper understanding on automotive engineering, the flow of all vehicle components working together, as well as the similarities and differences between them.
