Cracking of the clutch housing in automobiless is rare, but it should also be paid attention to, often reflecting a series of driving and vehicle problems. There are many reasons for the rupture of the clutch housing, let's analyze it slowly.
1. When the car is driving on uneven roads, the elastic support transmits the low-frequency interference force of the suspension to the engine, affecting the transmission and transmission shaft, causing them to undergo forced vibration on the elastic support. When the frequency of forced vibration is equal to the frequency of interference force and close to the natural frequency of the system, the vibration system has a resonance trend, and the power of resonance is very strong.
2. Dynamic imbalance of the crankshaft. The poor quality of the piston or connecting rod or the uneven operation of each cylinder (power or working interval time) can generate a certain frequency of interference force, and as the engine rotates, the frequency gradually increases. At idle speed, due to the frequency of forced vibration being closer to the fixed frequency of the vibration system, the vibration system tends to resonate, and the vibration amplitude is larger; At high speeds, the frequency of interference force is higher, and the frequency of forced vibration is much greater than the natural frequency of the vibration system. Therefore, the frequency of forced vibration is high and the amplitude is small, so there is a feeling of "tingling" when in contact with the engine. When this vibration is sensed between the engine and transmission, as the engine speed increases, the vibration intensity increases, causing the clutch to undergo fatigue fracture in the highly concentrated stress area of the clutch housing under alternating loads.
3. The imbalance of automobiles clutches and automobiles clutch accessories, as well as the interference force caused by severe wear of the first shaft spline of the transmission, also causes forced vibration of the engine on the elastic support, generating alternating stress on the clutch and causing fatigue fracture.
4. The interference force caused by the dynamic imbalance of the transmission shaft causes the transmission to undergo forced vibration on the elastic support. Due to the high inertia of the engine, this vibration is sensed between the engine and the transmission, causing the clutch housing to withstand the speed fluctuations caused by alternating loads, which also need to be fed back to the crankshaft, causing the engine to undergo torsional forced vibration and causing fatigue fracture of the clutch housing.
5. The connection between the car engine, car clutch accessories, and transmission is equipped with precise positioning devices to ensure the coaxiality of the first shaft and crankshaft of the transmission. If the coaxiality exceeds the limit value, it will cause motion interference and may also cause the clutch housing to rupture.
6. The quality of the clutch housing itself or the stress caused by the deformation of the frame are both the reasons for the rupture of the clutch housing. Sometimes cars are subjected to strong impacts, such as collisions or rollovers, which can also cause the clutch housing to rupture at once.
Although many factors are due to human force majeure, it is necessary to determine whether there is a problem with the performance of the car itself. Experienced and attentive drivers will find that the entire car is a relatively complex system. If there is a problem in any part of the system, the entire system will collapse at any time, even without warning. The reason why cars are on strike at any time is that.
