Sequential gearbox
A sequential gearbox is a type of manual transmission in which the gears are changed sequentially, one after the other, like on a motorcycle. Unlike traditional manual transmissions, which require manipulating the gear lever through an H-pattern to change gears, a sequential transmission uses a paddle- or lever-style shifter.
How does a sequential gearbox work:
*Upshifting: The steering wheel paddle or lever pulls downward, shifting sequentially to a higher gear.
* Downshift: The steering wheel paddle or lever is pushed upward, shifting downwards in sequence.
* Neutral: A separate button or lever is required to shift to neutral.
Advantages of sequential gearboxes:
* Fast Gear Shifting: Sequential gearboxes allow you to change gears quickly as there is no need to move the lever in different directions.
* Improved Handling: Paddle shifters or levers can be mounted close to the steering wheel, allowing the driver to change gears without taking their hands off the steering wheel.
* Power Shift Capability: Sequential transmissions allow you to shift gears even when the throttle is applied, resulting in smoother, more flexible shifts.
*Improved Fuel Economy: Sequential transmissions can sometimes have a wider range of gear ratios, allowing the engine to operate at more optimal levels, resulting in fuel savings.
Disadvantages of sequential gearboxes:
* Complexity: Sequential transmissions are more complex and expensive to manufacture than traditional manual transmissions.
* Less reversibility: Sequential gearboxes have more limited reversibility capabilities.
*Adjustment: Drivers accustomed to traditional transmissions may need time to adapt to sequential transmissions.
Application of sequential gearboxes:
Sequential transmissions are often used in racing and performance vehicles where fast and efficient gear changes are required. Lately they have also become increasingly popular in production cars.
