Description
Technical field
The utility model relates to mechanical technique, particularly relates to a kind of quarry tipper middle part torsion cylinder assembly.
Background technology
Quarry tipper is a kind of large-scale non-highway transport vehicle, the features such as it has, and weight is large, work under bad environment, stream time length, and the intensity of the concentrated force part to car load and reliability have harsh requirement.Carriage of mining self-unloading vehicle is the core component of whole quarry tipper, and the load of car load and power are delivered to all parts of car load completely by vehicle frame.The middle part torsion cylinder assembly (hereinafter to be referred as torsion cylinder assembly) of vehicle frame is being born and is being supported cargo box hoisting, connecting back axle to transmit the vital function of car load power, it is one of quarry tipper the most concentrated stressed position, if destroying appears in this assembly structure in car load operational process, will cause major accident.
Middle part torsion cylinder assembly not only needs to connect back axle but also need to support elevating ram, and these functions have determined that its structure must be made from multiple components.But if its multiple parts all adopt welding connecting mode can form too much weld seam, these weld seams can increase the quantity of stress concentration portion position, thereby easily cause vehicle frame cracking, and be difficult to the overall performance of Assurance component.
Existing quarry tipper middle part torsion cylinder assembly structure as shown in Figure 1, it mainly comprises torsion cylinder 1, thrust frame 2 and load lifting cylinder bearing 3, torsion cylinder 1 and load lifting cylinder bearing 3 are directly welded on left and right longeron, thrust frame 2 adopts the Split type structure of left and right ear seat, left and right ear seat is also directly welded on torsion cylinder, thereby forms multiple weld seams 5.Because thrust frame 2 is connect back axle and transmit that car load advances and the parts of the power that falls back, through hole coordination hinge axle and rear-axle casing in the middle of it are hinged, adopt split type welded structure not only cannot guarantee the rigidity of its structure, and on its left and right ear seat, the right alignment of hinge hole is also difficult to meet design requirement; Moreover thrust frame easily produces stress and concentrates under Dynamic Loading at weld seam position, from manufacturing process angle, these connecting portions are also difficult for realizing rounding off to fall stress concentration.
