Problems solved by technology

[0003] The high-frequency vibration generated during the driving process of the car has a great impact on the driving comfort of the occupants. The commonly used types of mounts mainly include bush mounts, hydraulic mounts and air mounts. The bush mounts have a simple structure and low cost, but The vibration reduction effect is not ideal, and the hydraulic suspension and air suspension have good vibration reduction effects, but the structure is complicated and the cost is high

Embodiment 1

[0024] Such as figure 1 As shown, the suspension according to one embodiment of the present invention includes a first magnetic element 1, a second magnetic element 2 placed above the first magnetic element 1, and an elastic air cavity between the two magnetic elements. The air cavity is filled with gas with a certain pressure (for example: air), and the opposite sides of the two magnetic elements have the same magnetic properties, that is, the two magnetic elements are arranged in the same way (S-S / N-N) with the same magnetic poles facing each other. Both magnetic elements can be permanent magnets or electromagnets, which are not considered as limitations on the technical solution of the present invention. The mount combines the commonality of the magnetic levitation mount and the air mount. Under the load, the two magnetic elements move relative to each other, compress the elastic air cavity, and the magnetic repulsion force and the elastic force of the gas work together to ...

Embodiment 2

[0028] Such as Figure 2-3 As shown, the elastic air chamber can also be an annular airbag 5, at this time, the first boss of the first magnetic element and the second boss of the second magnetic element 2 are all embedded in the space 5-1 surrounded by the annular airbag to fix, Thus forming the suspension of the present invention.

Abstract

The invention discloses a suspension, and belongs to the technical field of auto parts. The suspension comprises a first magnetic element (1), a second magnetic element (2) which is arranged above the first magnetic element (1) and an elastic air cavity which is arranged between the two magnetic elements. The elastic air cavity is full of air. Magnetism of one sides of the first magnetic element (1) and the second magnetic element (2) is the same, wherein the sides of the first magnetic element (1) and the second magnetic element (2) are opposite. Generality of magnetic levitation suspension and air suspension is combined, the shortcoming that the magnetic levitation suspension is smaller in provided carrying capacity is made up through elastic effects of closed air and the air cavity in the suspension, and compared with the air suspension, the suspension is simpler in structure and is easy to achieve. The suspension has variable stiffness and variable damper features of the magnetic levitation suspension and the air suspension, is good in damping effects, and especially isolates high-frequency vibration better.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a suspension. Background technique [0002] Mounting is an important part to reduce vibration and shock. Mounting is not only a connecting device, but its stiffness and damping characteristics also affect the noise, vibration, and harshness (NVH) characteristics of the entire system, such as automobile Suspension in . [0003] The high-frequency vibration generated during the driving process of the car has a great impact on the driving comfort of the occupants. The commonly used types of mounts mainly include bush mounts, hydraulic mounts and air mounts. The bush mounts have a simple structure and low cost, but The vibration reduction effect is not ideal, and the hydraulic suspension and air suspension have good vibration reduction effects, but the structure is complicated and the cost is high. Contents of the invention [0004] (1) Technical problems to be solved [0005...
