Description

Technical Field

[0001] The utility model relates to the technical field of rubber shock absorption, in particular to an automobile rubber vibration absorber. Background Art

[0002] Existing technical solutions address vibration isolation between the vehicle body and chassis by using an elastic suspension connection between the vehicle body and frame. While early in vehicle development, only elastic suspension vibration isolation was considered, later in the development process, dynamic vibration absorbers became necessary to address specific vibrations.

[0003] When a vehicle is driving over an uneven road, the vehicle body will be impacted, causing local resonance of the structure, which is not only detrimental to the strength and life of the structural parts, but also reduces the comfort of the entire vehicle. To this end, we propose an automotive rubber shock absorber. Utility Model Content

[0004] The purpose of the utility model is to provide a rubber vibration absorber for an automobile to solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a rubber vibration absorber for an automobile, comprising a shell and a counterweight mass block, wherein a first rubber structure is installed on both sides of the counterweight mass block, and the two first rubber structures are connected to the shell on the side away from the counterweight mass block; the shell is located below the counterweight mass block and is equipped with a second rubber structure.

[0006] Preferably, the shell is U-shaped, and a fixing hole is provided at the bottom of the shell.

[0007] Preferably, the edge of the first rubber structure is a U-shaped concave structure.

[0008] Preferably, a through hole is provided in the middle of the first rubber structure, and a gap is provided between the top of the second rubber structure and the bottom of the counterweight mass block.

[0009] Preferably, the first rubber structure is a solid structure, and a gap is provided between the top of the second rubber structure and the bottom of the counterweight mass block.

[0010] Preferably, the first rubber structure is a solid structure, and the top of the second rubber structure is in contact with the bottom of the counterweight mass block.

[0011] Compared with the prior art, the beneficial effect of the present invention is that, through the action of the counterweight mass block, the first rubber structure and the second rubber structure, when the vehicle is running and causes large vibrations in the local structure, the vibration absorber starts to work and, under the action of external force, vibrates at its unique natural frequency and generates a reaction force, thereby reducing the vibration of the structure.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0019] See also Figure 1 In an embodiment of the utility model, a rubber vibration absorber for an automobile includes a shell 1 and a counterweight mass block 3. First rubber structures 2 are installed on both sides of the counterweight mass block 3, and the two first rubber structures 2 are connected to the shell 1 on the side away from the counterweight mass block 3; the shell 1 is located below the counterweight mass block 3 and is installed with a second rubber structure 4. The shell 1 is U-shaped, and a fixing hole 5 is opened at the bottom of the shell 1. The edge of the first rubber structure 2 is a U-shaped concave structure; through the action of the counterweight mass block, the first rubber structure and the second rubber structure, when the local structure vibrates greatly due to the vehicle running, the vibration absorber starts to work. Under the action of external force, it vibrates according to its unique natural frequency and generates a reaction force, thereby reducing the vibration of the structure.
