# the composition and functioning of the car moving system #
The vehicle transmission system consists mainly of a series of key components that work in concert to ensure that the vehicle is functional under various conditions of operation. Its main components and respective roles are as follows:
**1. Engines**
Engines are the engine of cars and are responsible for converting the chemical energy of fuel into mechanical energy and output power. It is the starting point for the entire transmission system and provides the necessary power support for cars。
**2. Collider**
The clutch is located between the engine and the transformer and is responsible for transmitting or cutting power between the engine and the transformer. By operating the clutch pedal, the driver separates or binds the clutch, thus achieving a smooth break. The main function of the clutch is also to stabilize the vehicle, to facilitate engine start-up, to limit the transposition and to prevent overloading of the transmission system。
**3. Translators**
The main function of the transformer is to change the drive ratio, i. E. To adjust the rotation ratio between the engine curve axis and the driver to accommodate different speeds and road conditions. It can also reverse the vehicle and, if necessary, interrupt the power transmission. The types of transformers are diverse and include manual transformers (mts), liquid mechanical automatic transformers (ats), ungraded transformers (cvts), etc。
**4. All-way transmission devices**
The all-way transmission device is the key to the power transfer of the vehicle's transmission system and is used primarily to transfer power between the inter-axis angles and the converses whose relative position is constantly changing. It consists of parts such as velocities, which compensate for the distance differentials between axes and guarantee the continuity of power transmission during car travel。
**. 5. Driving bridges**
The bridge consists of the main brake, the differential, the half-axis and the bridge shell. The main function of the main brake is to increase speed and change the direction of power transmission. The speed differential is used to resolve the problem of inconsistent wheel speeds in and around the car's turn and to enable it to move smoothly. The half axle is responsible for transmitting the power of the speed differential to the wheel, which produces rotation。
**6. Tyres**
Tyres are the final output components of the car moving system, which are in direct contact with the ground, absorb the weight of the vehicle and provide vehicle mobility. The performance of tyres directly affects the pull, brake performance and motor stability of cars。
The role of the car moving system is mainly in the following areas:
* **secure gravity and speed**: the moving system ensures that vehicles have the required pull and speed under various conditions of movement and coordinates the change between pull and speed to accommodate different driving environments。
:: ** upgrading power and fuel economy**: through efficient power transmission, the transmission system is able to use engine output power more efficiently, while reducing fuel consumption and increasing fuel economy in cars。
* ** rewind function achieved**: transmission system transformer has a reverse block to enable vehicle back-up function。
* ** interruption of power transmission**: during start-up engine, change-of-block or short-term parking, the transmission system is able to integrate and rapidly separate power transmissions in a smooth manner, as required, to ensure that the engine does not turn off and to protect the transmission system。
Based on the above, the vehicle movement system is a complex and sophisticated one, where components work together to ensure that the vehicle is safe under various conditions
