Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption structures for excavator radiators, and particularly to an internal combined suspension shock absorption structure for an excavator radiator. Background Art

[0002] In the prior art, the internal shock absorption structure of an excavator radiator is crucial for ensuring its stable operation under the harsh working conditions of the excavator and extending its service life. The design purpose of the shock absorption structure inside the radiator is to reduce vibration.

[0003] Due to the large mass of the radiator and the poor working environment of the excavator, generally a protection frame with a relatively large rigidity needs to be added outside the radiator to prevent external forces such as vibration from directly acting on the radiator. In addition, suspension points need to be set on the protection frame. The internal shock absorption method for a single excavator radiator is usually four-point suspension, and three-point suspension can also be adopted. Among them, there are two main suspension points and two or one auxiliary suspension points.

[0004] All suspension points are arranged on the same component assembly to improve the stress condition of the radiator and minimize the vibration intensity of the radiator as much as possible. A flexible non-metallic material such as a rubber pad or a rubber sleeve is used to transition between the main suspension point and the component assembly it is connected to for the purpose of shock absorption. The compression amount of the rubber pad at the main suspension point is generally 3% - 5% of its free height.

[0005] The existing shock absorption structures for excavator radiators in the prior art, for example: "A shock absorption installation structure for an excavator radiator" disclosed in Publication (Announcement) No.: CN209653019U; for example: "A shock absorption mechanism for an excavator radiator" disclosed in Publication (Announcement) No.: CN217814736U, etc. In the existing technical solutions, the setting of the shock absorption structure is usually too complex, resulting in an unsatisfactory shock absorption effect, and the installation of the shock absorption structure is not convenient enough.
