What is a Transmission Composed of?

Transmission consists of two main parts: the gear transmission mechanism and the gear shifting control mechanism. The primary function of the gear transmission mechanism is to alter the magnitude and direction of torque and rotational speed; while the main role of the control mechanism is to manage the transmission mechanism, enabling changes in the transmission ratio, i.e., facilitating gear shifts to achieve speed and torque variation. More related information is as follows: 1. Structural Features: Simple transmissions offer advantages such as high efficiency, straightforward construction, and ease of use, but they have fewer gears and a limited range of i variation (traction force and speed range), making them suitable only for certain vehicles with fewer gears. 2. Principle: Mechanical transmissions primarily utilize the speed reduction principle of gear transmission.
The basic structure of a transmission is quite interesting. I've learned that the core component is the gear set, which includes an input shaft connected to the engine and an output shaft that drives the wheels, with various-sized gears in between to adjust speed. In a manual transmission, there's an additional clutch pedal and gear shift mechanism, allowing you to manually select gears. Automatic transmissions are more complex, featuring a torque converter to smooth out gear shifts, planetary gear sets to achieve different speed ratios, and hydraulic systems with electronic control units to automatically switch gears. Overall, the transmission also contains auxiliary components like bearings and synchronizers to ensure smooth and efficient power transfer. If these parts wear out excessively, issues like slipping or sluggish shifting may occur, requiring timely maintenance and part replacement.
The transmission is actually a combination of a series of components. From my daily experience, a manual transmission mainly consists of gears, main and secondary shafts, and a gearshift lever, allowing you to change gear ratios by operating the lever; an automatic transmission includes a torque converter, planetary gear sets, a hydraulic pump, and a control computer, automatically handling speed changes. The gear set is the key to power conversion, with the input shaft connected to the engine force and the output shaft transmitting it to the drive wheels. It's also essential to consider the sealing of oil seals and the housing to prevent oil leaks. The quality of the transmission affects the entire vehicle's responsiveness, and only with ingenious design can it avoid jerking and provide a smoother driving experience.
