The invention discloses a cross-linking magnetic levitation suspension external connecting sleeve for road noise control. The cross-linking magnetic levitation suspension external connecting sleeve includes an outer shell, a piston rod, an electromagnet, a permanent magnet, a spring, an electromagnet control electrode and an electrode brush, the outer shell is of a hollow structure, the electromagnet, the permanent magnet and the spring are located inside the outer shell, the outer shell is provided with an outer shell through hole, the piston rod is arranged in the permanent magnet and the electromagnet in a penetrating mode through the outer shell through hole, and the electromagnet control electrode passes through the outer shell and the permanent magnet to be connected with the electromagnet; the electromagnet control electrode is of a cylindrical structure, and the outer surface of the electromagnet control electrode is connected with the electrode brush; and the electromagnet andthe permanent magnet are connected through the U-shaped spring, during power off, and the spring plays a supporting role to ensure safety of the structure. According to the cross-linking magnetic levitation suspension external connecting sleeve for road noise control, a levitation structure mode of 'permanent-electricity-permanent' is adopted, and by changing the current direction of the electromagnet, not only can the attraction between poles be used for working, but also the repulsion can be used for working.
Description
technical field [0001] The invention belongs to the technical field of automobile systems and structures, and in particular relates to a cross-linked magnetic suspension external connection sleeve for road noise control. Background technique [0002] In recent years, in order to make the car have more ideal vibration and noise performance, rubber components are widely used in the connection of suspension components. As a damping element of the suspension, it has an important influence on the high-frequency vibration transmission characteristics. Today, the specifications for suspension rubber components specify a static stiffness and a dynamic stiffness at one or both low frequencies. There is no specification for small displacement stiffness requirements including 100Hz or higher frequencies, and secondly, the rubber components cannot adaptively absorb the vibration energy transmitted by the suspension. For example, the road surface is an important excitation source for t...
