how does a splitter gearbox work?

A splitter gearbox is a type of transmission that allows for a greater range of gear ratiOS by dividing the power between two different sets of gears. It typically features a main gear set and an auxiliary gear set, which can be engaged or disengaged to provide either a standard gear ratio or a lower/higher ratio for specific driving conditions. This mechanism enables smoother transitions between gears and enhances the vehicle's performance by optimizing power delivery and fuel efficiency. Essentially, it allows drivers to "split" the available gears, improving versatility in various driving scenariOS.
