The invention discloses a vibration and noise reduction device used for a vehicle body and capable of improving the NVH performance of the vehicle. A driving connecting rod is arranged between a frontvehicle driving part and an armor bottom plate and is used for transmission output, so when the vehicle body passes through the bottom end of a pit, the force can be directly transmitted to two groups of wheel bodies, and when the force is transmitted to the wheel bodies in the figure, the force is firstly contacted with a rotating shaft body, bolts welded on the outer wall of the rotating shaftbody can guide force into a convex upper frame and a bottom frame, the bottom frame and the convex upper frame are connected through a semi-arc bracket, the force is separated to the bottom frame andthe protruding upper frame, the bottom frame inclines upwards, the force is transmitted to a opposite L-shaped connecting body through a first spring body connected with a locking bolt, and the opposite L-shaped connecting body ascends and descends after being damped through the first spring body, and the damping effect is achieved.
本发明公开了一种提高车辆NVH性能的车身用减振降噪装置。本发明中的车身用减振降噪装置,在前车驱动部件与装甲底板之间安装驱动连接杆用于传动输出,当车体经过坑洼底端的时候,力度将会直接传输到两组车轮体上,当力度传输到图中的车轮体处,力度最先接触到转轴体上,并在转轴体的外壁上所焊接的螺栓将会把力度导入凸起上架和底架上,而底架和凸起上架之间通过半弧支架进行连接,力度分离到底架和凸起上架上,底架的将会向上倾斜,并通过锁紧栓所连接的第一弹簧体将力度传输到对向L形连接体上,而对向L形连接体将会通过第一弹簧体的减震后,将会进行升降,并达到减震的效果。
