The Transmission and transmission system of gears are two common concepts in mechanical devices, and they have the following differences: definition and function: Transmission refers to the device that converts the output torque of the engine into the required torque of the wheel and realizes the gear change ratio adjustment. It changes the speed ratio between the input and output shafts through different gear combinations to achieve vehicle acceleration, deceleration and speed change. The Powertrain System refers to the entire mechanical transmission device, including the engine, transmission, transmission shaft, differential and other components. The transmission system transmits the power generated by the engine to the wheels to complete the operation of the vehicle. Components: Transmission usually refers to the transmission device in the car, which is composed of a number of gears, clutches, shifting mechanisms, etc. The drive system covers a wider range, including in addition to the gearbox, the engine, clutch, drive shaft, transmission chain (such as chain drive or belt drive) and other components. Function range: The gearbox is mainly responsible for adjusting the speed ratio between the engine output torque and the wheel speed, and realizes the vehicle speed change and ADAPTS to different driving conditions through different speed change ratios. The drivetrain takes on a broader role, including the transfer of kinetic energy generated by the engine to the wheels, and may also cover components such as the four-wheel drive system and differential. Application: Gearbox is mainly used in cars, motorcycles and other vehicles, and other equipment that needs to use gear movement to achieve power transmission and speed regulation. The transmission system is widely used in a variety of equipment and mechanical devices, such as automobiles, motorcycles, construction machinery, agricultural machinery and other power equipment. In general, the gearbox is an important part of the transmission system, and the transmission system is a broader concept that includes more components related to power transmission.
