a) The primary purpose of a sliding-mesh type gearbox is to provide multiple gear ratios by sliding different gears into mesh with the corresponding gears on the output shaft. This type of gearbox allows for quick and easy gear changes but can be less smooth compared to other types. On the other hand, the constant-mesh type gearbox is designed to provide gear ratios without the need for sliding gears. Each gear in a constant-mesh gearbox is constantly in mesh with its corresponding gear on the output shaft, which results in smoother gear changes.
Пример: For example, in a sliding-mesh type gearbox, when shifting from first to second gear, the gear on the output shaft is disengaged and the gear corresponding to the second gear is engaged, allowing the transmission of power in a higher gear ratio.
Совет: To understand the purpose of these types of gearboxes, it is important to grasp the concept of gear ratios and how they affect vehicle performance. Additionally, studying the design and operation of gear systems can help in understanding the functioning of sliding-mesh and constant-mesh gearboxes.
Упражнение: What are the advantages and disadvantages of using a sliding-mesh type gearbox over a constant-mesh type gearbox?
