The invention provides a vacuum pump assembly and a vehicle. The vacuum pump assembly comprises an electronic vacuum pump, a pump support, first vibration isolation devices and second vibration isolation devices, wherein the electronic vacuum pump is fixedly connected with the pump support through bolts and nuts, each first vibration isolation device and each second vibration isolation device arearranged on one bolt in a sleeving mode, either the first vibration isolation devices or the second vibration isolation devices or both the first vibration isolation devices and the second vibration isolation devices are fixed to the electronic vacuum pump, each first vibration isolation device is located between the pump support and the head of the corresponding bolt, and each second vibration isolation device is located between the pump support and the corresponding nut. According to the vacuum pump assembly, vibration transmitted from the electronic vacuum pump to the pump support is buffered through components, fixed to the electronic vacuum pump, in the first vibration isolation devices and the second vibration isolation devices; the first vibration isolation devices can buffer vibration transmitted from the heads of the bolts to the pump support to realize first-stage vibration isolation; the second vibration isolation devices can buffer vibration transmitted from the nuts to thepump support to realize second-stage vibration isolation; and therefore, the vibration isolation effect is enhanced, the NVH level is raised, and then EVP noise is lowered.
本发明提供了一种真空泵总成和车辆,真空泵总成包括电子真空泵、泵支架、第一隔振装置和第二隔振装置,电子真空泵与泵支架通过螺栓、螺母固定连接,第一隔振装置和第二隔振装置均套设在螺栓上且两者中的至少一者固定在电子真空泵上,第一隔振装置位于泵支架与螺栓的头部之间,第二隔振装置位于泵支架与螺母之间。本发明通过第一隔振装置和第二隔振装置中固定在电子真空泵上的部件缓冲电子真空泵传递给泵支架的振动;第一隔振装置能够缓冲螺栓头部传递给泵支架的振动,实现一级隔振;第二隔振装置能够缓冲螺母传递给泵支架的振动,实现二级隔振;所以增强了隔振效果,提升了NVH水平,进而降低了EVP噪音。
