What is the function of a transmission coupling?

The function of a transmission coupling is to connect the power source (usually an engine or motor) to the working machine, transmitting torque through changes in the liquid's angular momentum. Below are the specific functions of a transmission coupling: 1. Clutch function: Automatic transmission couplings have a clutch function. Speed-regulating and clutch-type hydraulic couplings can start or brake the working machine without stopping the motor, expanding the stable operating range of the power machine. 2. Energy-saving function: It can reduce the motor's starting current and duration, lessen the impact on the power grid, and decrease the motor's installed capacity. The energy-saving effect is significant for large-inertia, hard-to-start machinery using torque-limiting hydraulic couplings and centrifugal machinery using speed-regulating hydraulic couplings.
The transmission coupler, also known as the torque converter, plays a crucial role in automatic transmission vehicles. It connects the engine and the transmission, ensuring smooth power delivery. Simply put, it acts like a fluid torque amplifier, enhancing torque during startup to help the car move off easily, while allowing the engine to keep running without stalling when stopped—this is particularly friendly for novice drivers. I remember while driving, it reduced harsh jerks, making gear shifts smoother, especially in congested traffic. Inside, it consists of three parts: the impeller that propels transmission fluid, the turbine that receives power, and the stator that enhances torque. However, modern models may use a lock-up coupler, which directly connects the engine and transmission at high speeds to improve efficiency and save fuel. Thus, it's not just a mechanical component but also enhances driving comfort and safety. Regular checks of fluid levels and wear are essential to avoid faults that could cause delayed response.
After years of driving, I believe the torque converter is a great helper for automatic transmissions, ensuring smoother operation. Its role is to cushion impacts—for example, when you press the accelerator to start, it can amplify the power to make the car move forward smoothly, eliminating the worry of stalling like in a manual transmission. At a red light, the engine keeps running, but the car doesn’t move, making it much more convenient. I’ve also noticed that it uses fluid coupling to absorb vibrations, reducing gear wear and extending the transmission’s lifespan. However, be cautious—if the torque converter ages or leaks oil, issues like slipping or strange noises may arise, causing poor acceleration and increased fuel consumption. In such cases, it’s best to visit a repair shop immediately for inspection and replacement. For daily driving, I recommend regular transmission fluid changes to maintain efficiency, saving money and ensuring safety.
