How Big is a Transmission?
1 Answers
The size of a transmission varies significantly across different vehicle models. Additionally, there are differences between manual and automatic transmissions, as well as between imported and domestically produced ones. The engine displacement also affects the size. Transmission Introduction: A transmission is a gearbox that alters the gear ratio and the direction of motion. It is located between the clutch and the central drive. Functions of a Transmission: Its primary functions are: changing the driving force and speed of the vehicle (shifting gears) without altering the engine's speed and torque; enabling the vehicle to reverse (direction change); and allowing the engine to idle without stalling (neutral gear). Based on the transmission form, gear-type transmissions can be categorized into three types: dual-shaft, triple-shaft, and compound. The dual-shaft type has two main shafts (excluding the reverse gear shaft) and achieves speed reduction through a single pair of gears. The triple-shaft type has three main shafts (input shaft, intermediate shaft, and output shaft) and achieves speed reduction through two pairs of gears. The compound type consists of two transmissions connected in series or parallel, allowing for more gear positions with fewer gears.
