Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] In the present invention, unless stated to the contrary, the used orientation words such as "upper and lower" generally refer to the upper and lower directions of the drawings, and "inner and outer" refer to the inner position relative to the outline of each component itself. ,outside.

[0035] like figure 1 As shown, the present invention provides a suspension, wherein the suspension includes an upper cover plate 1, a lower base plate 2 arranged opposite to the upper cover plate 1, and an elastic side wall fixed between the upper cover plate 1 and the lower base plate 2 3. The elastic side wall 3 is connected with the upper cover plate 1 and the lower ...

Abstract

The invention discloses a suspension and a vehicle. The suspension comprises an upper cover plate, a lower bottom plate opposite to the upper cover plate and an elastic side wall fixed between the upper cover plate and the lower bottom plate, wherein the elastic side wall, the upper cover plate and the lower bottom plate are connected to constitute a closed hydraulic chamber; a partition board is arranged in the hydraulic chamber and divides the hydraulic chamber into two cavities; damping holes are formed in the partition board, so that a damping liquid circulates between the two cavities through the damping holes. Therefore, when the suspension is subjected to low-frequency and large-amplitude vibration, the elastic side wall is subjected to compression deformation, accordingly, the damping liquid circulates in the two cavities and produces friction with the inner peripheral surface of the elastic side wall, the damping holes and the wall surface of the partition board, kinetic energy is converted into heat energy, meanwhile, part of kinetic energy can be absorbed through deformation of the elastic side wall, and vibration reduction in a low-frequency range is realized; when the suspension is subjected to high-frequency and small-amplitude motivation, the damping liquid almost has no time to flow and vibrates at a high speed together, so that the high-frequency dynamic stiffness of the suspension is improved, and dynamic hardening is eliminated.

Description

technical field [0001] The invention relates to the field of vehicle vibration reduction, in particular to a suspension and a vehicle using the suspension. Background technique [0002] Mount is used to reduce and control the transmission of engine vibration, and play a supporting role in the automotive powertrain. It is not only a connecting device, but its stiffness and damping characteristics also affect the NVH characteristics of the entire system, which is the key to reducing vibration and shock. important parts. [0003] The high-frequency vibration generated during the driving process of the car has a great impact on the 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 mount and the air mount have good vibration reduction effects, but the structure is complex and the cost is re...
