S Series Gearbox
Product Introduction of S Series Gearbox
The S Series Gearbox usually refers to the S - series dual - clutch transmission in automobiles, which is an advanced automotive transmission device. It adopts a dual - clutch structure, with two sets of clutches controlling odd - numbered gears and even - numbered gears respectively, enabling seamless power connection during gear shifting. This transmission can automatically or manually select the appropriate gear according to the vehicle's driving conditions and the driver's operating intentions, ensuring that the vehicle can achieve good power performance and fuel economy under various road conditions. This series of products is widely used in various mid - to - high - end automobile brands, bringing drivers an efficient, smooth, and driving - pleasure - filled driving experience.

1.Dual - clutch Structure: Equipped with two independent clutches, one set is responsible for odd - numbered gears, and the other is for even - numbered gears. This allows the gear - shifting preparation and the power transmission of the current gear to occur simultaneously, laying the foundation for fast gear - shifting and smooth power transmission.
2.Intelligent Gear - shifting Logic: It has a built - in advanced electronic control system that can accurately sense various driving parameters such as vehicle speed, accelerator pedal position, and engine speed. Based on the preset gear - shifting strategies, it can intelligently and quickly determine when to perform gear - shifting operations, achieving intelligent and precise gear - shifting.
3.High Transmission Efficiency: During the power transmission process, there is less power loss. It can efficiently transmit the engine's power to the wheels, effectively reducing energy consumption and enhancing the vehicle's overall performance and fuel economy.
4.Compact Design: Under the premise of ensuring functionality and performance, it adopts a compact layout and design, occupying less space in the vehicle. This facilitates flexible arrangements for automakers in vehicle design and layout, which is conducive to the lightweight and miniaturization of vehicles.
5.Multiple Driving Modes: Generally, it has multiple driving modes such as eco - mode, sport - mode, and normal - mode, meeting the driver's choices under different road conditions and driving demands. For example, the eco - mode focuses on fuel economy, while the sport - mode emphasizes power performance.

1.Fast Gear - shifting Response: Compared with traditional transmissions, the gear - shifting speed is extremely fast. It can complete gear - shifting in an extremely short time, bringing drivers a more direct and smooth acceleration experience. It has more advantages during operations such as overtaking and rapid acceleration.
2.High Driving Comfort: The gear - shifting process is smooth with almost no jerk, effectively enhancing the driving and riding comfort. Whether driving at low speeds in urban congested traffic or cruising at high speeds, it allows passengers in the vehicle to enjoy a stable driving experience.
3.Good Fuel Economy: It can accurately shift gears according to the vehicle's driving state, enabling the engine to operate in the high - efficiency speed range as much as possible, thus reducing fuel consumption and fuel cost expenditures. It performs outstandingly in terms of energy conservation and environmental protection.
4.Powerful Power Output: Due to the extremely short power interruption time during gear - shifting, the vehicle can maintain a strong power output continuously. During acceleration, climbing, and other processes, the power is continuous, fully exerting the engine's performance potential.
5.Good Operational Convenience: It can shift gears automatically, making driving easier and more convenient, which is suitable for daily urban driving. It can also be shifted manually through paddle - shifters or the manual - shifting mode, satisfying the driver's pursuit of driving pleasure. It combines the convenience of an automatic transmission and the handling feel of a manual transmission.
