Large excavator working environment is more severe, and operating location is in surface mine, tunnel etc., when the activity duration is often long mostly
Between work continuously, and workload is also relatively strong, so proposes requirements at the higher level to excavator suspension system amortisseur.Excavator sets
Put suspension system, it is therefore an objective to which the vibration that dynamical element is delivered to supporting system is reduced to bottom line.
Large excavator suspension system amortisseur is usually upper and lower buckle-type at present, middle to be positioned using sleeve, outside
Flange, the intermediate sleeve sulfidization molding together with elastomer.The amortisseur of this structure is for large excavator, although short-term
It is interior to meet its job requirements, but elastomer major part is exposed in air, it is easily rotten by gases such as solar irradiation, ozone
Erosion affects its service life.
The content of the invention
The present invention provides a kind of large excavator suspension system amortisseur, using pyramid type shear pattern, its rubber bullet
Gonosome major part is included in enclosure interior, can reduce the external environment impact aging to rubber elastomer, and will not cause change
Shape is excessive, and affects the local damage of rubber elastomer inner structure, and then extends the service life of amortisseur.
To achieve these goals, a kind of large excavator suspension system amortisseur of the invention, including upper cover plate, bearing
Sulfuration body, axle sleeve and protection board sulfuration body；The protection board sulfuration body is provided with bearing sulfuration body, the bearing sulfuration body and guarantor
Backplate sulfuration body is fixed together by connector；Upper cover plate is installed above the bearing sulfuration body.
Further, set axle is provided between protection board sulfuration body and bearing sulfuration body.
Further, upper cover plate and bearing sulfuration body is fixed together by 6 hexagon-headed bolts, and with 6 taper bolts
Locking hexagon-headed bolt.
Preferably, connector is soket head cap screw, and pass through circular cone pin locked soket head cap screw.
Further, bearing vulcanizes body by rigidity part diminished shaft, taper sheath, lower support assembly, rubber elastomer I, rubber
III sulfidization molding of elastomer II and rubber elastomer, the lower support assembly are welded with base plate by undersetting；The rubber
Elastomer II and rubber elastomer III are located between diminished shaft and undersetting, and are separated with taper sheath, and the rubber elastomer I sets
Between base plate and protection board sulfuration body, and separated with taper sheath, with II arranged in series of rubber elastomer.
Further, protection board sulfuration body is sulfided into by rigid member protection board, rubber elastomer IV and rubber elastomer IV
Type, the rubber elastomer IV are located at rigid member protection board upper surface end positions, and the rubber elastomer IV is located at rigid member
Protection board bottom centre position.
Further, 4 fabrication holes are averagely disposed with around taper sheath medium position.
Further, IV bottom periphery position of rubber elastomer is provided with 2 fabrication holes.
Compared with prior art, the present invention adopts circular cone shear pattern, its rubber elastomer overwhelming majority to be wrapped in rigidity
In the exposed environment outside of part enclosure interior, only rubber elastomer II and III small part of rubber elastomer, therefore, bullet of the present invention
Gonosome is affected smaller by factors such as solar irradiation, the aging, ozone aging of oxygen.In addition, the present invention adopts position limiting structure, when which
When bearing excessive loads, can vulcanize body by axle sleeve and protection board carry out spacing, and deformation will not be caused excessive, rubber bullet is prevented
The local failure of gonosome inner structure, so as to extend amortisseur service life.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of large excavator suspension system amortisseur of the invention, mainly by including upper cover plate
1st, bearing sulfuration body 2 and protection board sulfuration body 4 are constituted；The protection board sulfuration body 4 is provided with bearing sulfuration body 2, the bearing
Sulfuration body 2 and protection board sulfuration body 4 are fixed together by connector；Upper cover plate 1 is installed above the bearing sulfuration body 2.
The connector is soket head cap screw 6, and locks soket head cap screw 6 by taper bolt 5.
In order to further extend the service life of the present invention, it is provided between the protection board sulfuration body 4 and bearing sulfuration body 2
Set axle 3, for spacing, when this amortisseur bears excessive loads, by axle sleeve 3 and protection board vulcanize body 4 carry out it is spacing, will not
Cause deformation excessive, prevent the local failure of rubber elastomer inner structure, such that it is able to extend amortisseur service life.
As shown in figure 1, for the ease of dismantling and keeping in repair, upper cover plate of the present invention 1 passes through 6 turret heads with bearing sulfuration body 2
