Abstract
The invention provides a high strength elastic body assembly for overturning a cab of a mine car. The high strength elastic body assembly comprises a high strength elastic polyurethane barrel body and a steel bushing which is arranged on the high strength elastic polyurethane barrel body in a lining mode. Lubrication grooves are formed in the inner circumferential face of the steel bushing, annular grooves are formed in the inner circumferential face of the high strength elastic polyurethane barrel body, and annular protrusions which are right matched with the annular grooves are formed at the positions, corresponding to the annular grooves, of the outer circumferential face of the steel bushing. The high strength elastic polyurethane barrel body and the steel bushing are compounded into a whole in a vulcanizing mode. The high strength elastic body assembly and cab overturning parts are assembled in a flexibility mode, axial and radial loads can be effectively borne, the cushioning function is also achieved, the structure is simple, manufacturing and split charging are easy, cost is low, the effect is good, and excellent economic benefits can be achieved.
Description
technical field
The present invention relates to high strength elastic body assembly for a kind of mine car driver's cab turnover.
background technology
The applying working condition of mine vehicle is severe, and during driving, its operator's compartment is subject to impacting larger.Driver's cab turnover assembly is the important stressed member of cab tilting system, and its higher damage rate is the problem of car load and component manufacturer headache always, and the main position of damage is at elastic body assembly.Traditional elastic body assembly adopts elastomeric material, and the elastic body of this material life-span under heavy duty and impact load is very short, and reliability is poor.Conventionally adopt now the elastic body assembly of whole sulfuration structure, the service life of this assembly is longer than conventional confguration, but the rubber elastomer of whole sulfuration is being subject under the external force combined actions such as torsion, deflection and extruding, the rubber of sulfuration easily comes unstuck, tears and extrudes, finally cause elastic body assembly failure, affect vehicle performance, so this assembly also exists certain limitation.For the cost of mine vehicle and operating mode are considered, be not suitable for adopting Pneumatic Suspension, but need to have suitable shock absorption device, therefore be badly in need of high strength elastic body assembly for a kind of suitable mine car driver's cab turnover.
summary of the invention
The technical problem to be solved in the present invention is to provide high strength elastic body assembly for a kind of mine car driver's cab turnover.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
High strength elastic body assembly for a kind of mine car driver's cab turnover, comprise high strength elastic polyurethane cylindrical shell and in be lining in the steel bushing on high strength elastic polyurethane cylindrical shell, on the inner peripheral surface of steel bushing, have oilway, on high strength elastic polyurethane internal circumference surface in barrel, there is annular groove, on steel bushing outer peripheral face, be formed with just in time with annular groove corresponding position the annular protrusion coordinating with annular groove, high strength elastic polyurethane cylindrical shell and steel bushing sulfuration are complex as a whole.
High strength elastic body assembly for above-mentioned mine car driver's cab turnover, oilway comprises front helix oilway, middle annular oilway and rear screw shape oilway, and front helix oilway, middle annular oilway and rear screw shape oilway are arranged in turn along axis direction.
High strength elastic body assembly for above-mentioned mine car driver's cab turnover, the annular groove on high strength elastic polyurethane internal circumference surface in barrel is spaced twice, accordingly, the annular protrusion on steel bushing outer peripheral face is spaced twice.
High strength elastic body assembly for above-mentioned mine car driver's cab turnover, at axis direction middle part, what high strength elastic polyurethane cylindrical shell outer peripheral face was provided with one annular falls rigidity groove.
The present invention is composited by high strength elastic polyurethane and Steel material, and the annular groove on high strength elastic polyurethane cylindrical shell and steel bushing faying face and annular protrusion can effectively prevent the axial separation of high strength elastic polyurethane cylindrical shell and steel bushing under load condition.On the inwall of steel bushing, have oilway, realize the lubricated of trip shaft, make driver's cab turnover more smooth-going.The present invention and the flexible assembling of driver's cab turnover part, can effectively bear axially and load radially, have cushioning effect again, simple in structure, is easy to manufacture and packing, and cost is low, effective, has fabulous economic benefit.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is cutaway view of the present invention.
In figure: 1 high strength elastic polyurethane cylindrical shell, 2 oilways, 3 steel bushings, 4 annular protrusions, 5 fall rigidity groove, 6 oilways.
The specific embodiment
As shown in Figure 1, mine car driver's cab turnover with high strength elastic body assembly comprise high strength elastic polyurethane cylindrical shell 1 and in be lining in the steel bushing 3 on high strength elastic polyurethane cylindrical shell.On the inner peripheral surface of steel bushing, have oilway (2 and 6), on high strength elastic polyurethane internal circumference surface in barrel, there is annular groove, on steel bushing outer peripheral face, be formed with just in time with annular groove corresponding position the annular protrusion 4 coordinating with annular groove, high strength elastic polyurethane cylindrical shell and steel bushing sulfuration are complex as a whole.
Oilway comprises front helix oilway, middle annular oilway and rear screw shape oilway, and front helix oilway, middle annular oilway and rear screw shape oilway are arranged in turn along axis direction.
Annular groove on high strength elastic polyurethane internal circumference surface in barrel is spaced twice, and accordingly, the annular protrusion on steel bushing outer peripheral face is spaced twice.
At axis direction middle part, what high strength elastic polyurethane cylindrical shell outer peripheral face was provided with one annular falls rigidity groove 5, can guarantee effectively to reduce assembly rigidity on the basis of the required hardness of assembly, improves damping effect.
