The invention relates to a passenger car transmission shaft supporting structure which comprises a transmission shaft supporting bracket and a bearing arranged in a lower through hole of the transmission shaft supporting bracket, a transmission shaft penetrates through an inner ring of the bearing, and a first vulcanized rubber layer is arranged on the inner surface of the lower through hole of the transmission shaft supporting bracket. When the engine transmits an exciting force to the driving shaft through the transmission shaft support, the vulcanized rubber layer in the transmission shaft support achieves the vibration isolation effect, and therefore energy transmitted to the transmission shaft by the engine is reduced. Meanwhile, the vulcanized rubber layer is added so that the supporting rigidity of the transmission shaft is reduced, and a resonance risk is decreased.
本发明涉及一种乘用车传动轴支撑结构,包括传动轴支撑支架,设置于传动轴支撑支架的下部穿孔内的轴承,传动轴穿过轴承的内圈,在传动轴支撑支架的下部穿孔的内表面设置有第一硫化橡胶层。当发动机将激励力通过传动轴支撑传递到驱动轴时,传动轴支撑内的硫化橡胶层起到了隔振效果,从而减小了发动机传递到传动轴的能量。同时增加硫化橡胶层使传动轴支撑的刚度降低,减小了共振的风险。
