Description

Technical Field

[0001] The utility model relates to the technical field of bushings, in particular to a high-toughness pressure-resistant rubber bushing. Background Art

[0002] Rubber bushings, when used in the automotive industry, serve as connecting nodes between various vehicle body components. They offer load-bearing, isolation, vibration attenuation, and noise reduction capabilities, reducing vehicle fatigue damage, improving vehicle performance, and enhancing ride comfort. However, most existing rubber bushings utilize the inherent elasticity of rubber for compression and shock absorption. In actual use, rubber bushings are subject to repeated load deformation, which can easily lead to fatigue damage and shorten their service life. Utility Model Content

[0003] The purpose of the utility model is to provide a high-toughness pressure-resistant rubber bushing, which absorbs radial loads inside and outside the bushing by arranging a buffer boss in a buffer space, reduces damage to the rubber material caused by vibration, and is conducive to improving the service life of the bushing.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-toughness pressure-resistant rubber bushing, comprising a bushing body, a cylindrical buffer lining is arranged inside the bushing body, the buffer lining comprises a lining body, and cylindrical buffer spaces are respectively opened on the inner and outer sides of the lining body, a cylindrical reinforcement plate is arranged between the two buffer spaces, and a number of annular buffer bosses are evenly arranged in the buffer space, and the top of the buffer boss is an arc structure.

[0005] Optionally, cylindrical balancing plates are provided on the inner and outer sides of the buffer liner respectively.

[0006] Optionally, an oil storage space is opened on one side of the bushing body close to the inner wall, and the oil storage space is filled with lubricating oil. An oil filling port is opened at one end of the bushing body, and a plurality of oil outlets are evenly opened on the inner wall of the bushing. The oil filling port and the oil outlet are both connected to the oil storage space, and the oil filling port is sealed by an oil plug.

[0007] Optionally, a cylindrical sound-absorbing cotton is provided on one side of the bushing body close to the outer wall.

[0008] The high-toughness pressure-resistant rubber bushing of the utility model has the following advantages:

[0009] (1) When the rubber bushing is subjected to radial pressure, it will squeeze the buffer boss in the buffer space. The buffer boss is made of elastic material. The buffer boss deforms under pressure and offsets the radial pressure. There is also enough reserved space in the buffer space to accommodate the deformation of the buffer boss, which will not cause additional burden on the buffer lining.

[0010] (2) The balance plate can disperse the radial pressure and avoid the situation of force concentration, which would cause serious damage to the local part of the bushing.

[0011] (3) The lubricating oil can be evenly dispersed on the inner wall of the rubber bushing through the oil outlet, which facilitates installation and reduces friction loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the cross-sectional structure of the present utility model. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a high-toughness pressure-resistant rubber bushing includes a bushing body 1, a cylindrical buffer lining 2 is provided inside the bushing body 1, and a cylindrical sound-absorbing cotton 3 is provided on the side of the bushing body 1 close to the outer wall. The sound-absorbing cotton 3 can play a role in noise reduction. An oil storage space 4 is provided on the side of the bushing body 1 close to the inner wall. The oil storage space 4 is filled with lubricating oil. An oil filling port 5 is provided at one end of the bushing body 1. A plurality of oil outlets 6 are evenly provided on the inner wall of the bushing. The oil filling port 5 and the oil outlet 6 are both connected to the oil storage space 4. The oil filling port 5 is blocked by an oil plug. Lubricating oil is added to the oil storage space 4 through the oil filling port 5. The lubricating oil can flow out through the oil outlet 6 and be evenly dispersed on the inner wall of the rubber bushing, which is convenient for installation and can also reduce friction loss. The buffer liner 2 includes a liner body, with cylindrical buffer spaces 7 defined on both the inner and outer sides of the liner body. Cylindrical balancing plates 8 are provided on both the inner and outer sides of the buffer liner 2. These balancing plates 8 disperse radial pressure on the liner body 1, preventing concentrated force that could cause significant damage to a portion of the liner body 1. A cylindrical reinforcement plate 9 is provided between the two buffer spaces 7 to enhance the strength of the buffer liner 2. Several annular buffer bosses 10 are evenly distributed within the buffer spaces 7, each with an arc-shaped top.

[0015] When the rubber bushing is subjected to radial pressure, the pressure first acts on the balance plate 8. This pressure is then distributed by the balance plate 8 and transferred to the buffer space 7, ultimately squeezing the buffer boss 10. The buffer boss 10 is made of an elastic material. Its deformation under pressure offsets the radial pressure. Furthermore, there is sufficient space within the buffer space 7 to accommodate the deformation of the buffer boss 10, without placing any additional strain on the buffer lining 2. Vibration primarily acts on the buffer bosses 10 on both sides, reducing damage to the rubber material and improving the service life of the rubber bushing.

[0016] The embodiments described above are only some embodiments of the present invention, not all 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.
