(1) car driving on uneven road, the elastic support the suspension of the low-frequency (1 ~ 1.6Hz) pass interference power the engine, transmission and spread shaft, elastic support to make the forced vibration. When the frequency of forced vibration frequency is equal to interfere with force and close to the system natural frequency, the vibration system has a resonance trend.
(2) the dynamic imbalance of the crankshaft, piston or connecting rod of the work of poor quality or non-uniformity of the Cylinder (power or work time) to have a certain frequency interference power, and with the improvement of the engine rotation, the frequency gradually increased , usually in the range 5 ~ 300Hz, high-speed engine is even higher. Idle, the closer the frequency of forced vibration of fixed frequency vibration system, vibration system, the trend has resonance, vibration amplitude greater; high speed, high frequency interference is the frequency of forced vibration is much larger than the natural frequency of vibration system Therefore, high frequency forced oscillation and the amplitude is small, so when in contact with the engine, the "pins and needles" feeling. When the sensor between the engine and transmission to the vibration, as the engine speed increased, vibration intensity increased, with the alternating load the clutch, the clutch part of a high concentration of crustal stress fatigue fracture.
(3) clutch and clutch plate of the unbalance, the first transmission shaft spline wear and tear caused serious interference power, also the elastic support on the engine for vibration, the clutch on the alternating stress, caused by fatigue fracture.
(4) shaft dynamic imbalance caused by the interference, giving the gearbox in the elastic support for forced vibration. As the engine's inertia (mass large), between the engine and transmission to the vibration sensor, under the clutch shell containing alternating velocity fluctuation cited, but also feedback to the crankshaft, causing the engine for the torsional vibration, but also the clutch housing fatigue fracture.
(5) engine, clutch and transmission have a precise connection between the positioning device to ensure that the first transmission shaft and crankshaft coaxial. If this coaxial over limit, will produce movement interference, can lead to rupture of the clutch housing.
(6) clutch housing itself, the quality (high concentration of internal stress, etc.) or frame deformation caused by stress, are the reasons for the breakdown of the clutch shell. Sometimes the car suffered a strong shock (such as roll-over), will lead to a one-time breakdown of the clutch housing.
