What components does the lock-up clutch consist of besides the driving part and the driven part?

Clutch is composed of transmission steel belt, pressure plate, flywheel, crankshaft, driven plate, front support ring, rear support ring, release hook, release bearing, transmission input shaft, clutch cover, diaphragm spring, etc. The following is the relevant introduction about the clutch: 1. Clutch: The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the transmission. During driving, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, so as to cut off or transmit the power input from the engine to the transmission. 2. The principle of releasing the clutch: The principle of releasing the clutch is: "slow first, fast second, and linkage third". When stepping on the clutch pedal, it should be fast and stepped to the bottom at one time. When lifting the pedal, the free travel should be fast, and it should be slow when approaching contact. When reaching the semi-linkage point, it should pause slightly, and then release. This is the process. The key point of this process is to find the semi-linkage point accurately. To control the speed well, the semi-linkage point is the dividing point. Lift it up fast and press it down slow, adjust downward, and choose the speed that suits you.
I've been driving for over a decade and often encounter issues with lock-up clutches. It mainly consists of an active part connected to the engine, a driven part linked to the transmission, and a locking component, typically a set of friction plates or clutch discs. This part is particularly important—when you're cruising steadily on the highway, it locks the torque converter to eliminate slippage, which saves fuel and reduces heat buildup. I remember once during a long road trip, the clutch lock-up failed, causing a sudden spike in fuel consumption and noticeable shuddering. After taking it to the shop, the mechanics confirmed it was due to worn friction plates. Experts say neglecting maintenance easily leads to such issues, so it's crucial to regularly check transmission fluid. If the locking component fails, you'll feel jerky gear shifts, and addressing it early can save a lot of hassle.
As a seasoned veteran who has worked on numerous automatic transmission vehicles, I've seen plenty of lock-up clutch structures. It consists of three main components: the driving section connected to engine output, the driven section linked to the driveshaft, and a locking element like friction disc assemblies. The locking mechanism is most critical - when engaged, it boosts efficiency by preventing hydraulic losses. Common repair issues include oil contamination causing slippage or premature wear - I recommend replacing friction discs every 60,000 km. During daily driving, you can easily tell it's working properly when the sound stabilizes around 60 mph after acceleration, unlike more complex components. Shorter oil change intervals will extend its lifespan.
