Abstract
The utility model discloses an improved agricultural recessed trailer axle. The trailer axle comprises an axle tube and axle heads arranged at two ends of the axle tube; the axle heads adopt extension axle heads; the overlapping sections between the axle heads and the axle tube are in submerged arc welding connection; and two lateral plates used for welding and reinforcing are additionally arranged on two main stressed surfaces at the welding joints. As the axle heads and the axle tube have longer overlapping parts welded through submerged-arc welding, and the strength character of the submerged-arc welding joint is more than two times stronger than a common welding joint, the connection strength of the axle heads and the axle tube is effectively improved; and as two reinforcing plates used for welding are additionally arranged on the two main stressed surfaces after the submerged-arc welding, the trailer axle is endowed with the bearing capacity of 12 T loads.
Description
Technical field
The utility model relates to a kind of agricultural recessed formula Trailer car shaft.
Background technology
See also Fig. 1, exist certain height poor between the carrying central siphon 1 of existing agricultural recessed formula Trailer car shaft and the spindle nose 2, make in the trailer driving process center of gravity low, be mainly used in the agricultural occasion of low speed, low load-carrying requirement.Its carrying central siphon 1 mainly is to utilize connecting panel 3 weld togethers with spindle nose 2, has the low problem of load-carrying capacity, generally below 8T; And the brake facing width of drg is bad at the following braking effect of 100mm.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model provides the agricultural recessed formula trailer axle of a kind of improved type, improves the load-carrying capacity of axletree.
To achieve these goals, the technical solution of the utility model is: the agricultural recessed formula trailer axle of a kind of improved type, comprise central siphon and the spindle nose that is arranged on these central siphon two ends, described spindle nose is the lengthening spindle nose, described spindle nose is connected by submerged-arc welding seam with overlapping region between the central siphon, and increases by two brace panels at two main stress faces of weld and carry out reinforcement of weld.
The drg that is installed on the described spindle nose comprises brake facing and shoes, between brake facing and the shoes by machine riveting together.
The width of described brake facing is more than 180 millimeters.
The first-class height of described diaxon, the axis keeping parallelism of the axis of two spindle noses and described central siphon.
Be installed between wheel hub on the described spindle nose and the wheel hub cover and be provided with the storage area.
Compared with prior art, spindle nose of the present utility model and central siphon have long overlapping part, and weld with submerged arc-welding at overlapping part, the strength character of submerged-arc welding seam improves more than the twice than the intensity of common welded seam, can improve the Joint strenght of spindle nose and central siphon effectively, in addition, after carrying out submerged arc-welding, increase by two brace panels again and weld, so just can make axletree have the ability of carrying 12T load for two main stress faces.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the prior art constructions scheme drawing.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is an assembling scheme drawing of the present utility model.
The specific embodiment
See also Fig. 2 and Fig. 3, the agricultural recessed formula trailer axle of the improved type of present embodiment comprises central siphon 1 and the spindle nose 2 that is arranged on these central siphon 1 two ends, and integral body forges out the lengthening spindle nose, then spindle nose 2 and central siphon 1 is carried out whole modifier treatment.This spindle nose is that unitary solid forges and forms with the lengthening position, has very enough intensity.The lengthening position of this spindle nose and central siphon have long overlapping part, and weld with submerged arc-welding at overlapping part, and the strength character of submerged-arc welding seam improves more than the twice than the intensity of common welded seam, can improve the Joint strenght of spindle nose and central siphon effectively.In addition, after carrying out submerged arc-welding, increase by two brace panels 3 again and weld, so just can make axletree have the ability of carrying 12T load for two main stress faces.
Along with the raising of load-carrying capacity, also to do corresponding improvement to the deceleration and stopping performance of axletree.The drg of the agricultural axle of tradition is fairly simple, and the brake facing width is below 100mm, and major part is an adhesive type.Be to link together by bonding method between brake facing and the shoes, the Joint strenght of brake facing and shoes is limited, makes the single-piece deceleration and stopping performance limited.Brake facing 4 width that are installed in the drg on this practical spindle nose reach 180mm, and are increased to the 220mm technical reserve.When increasing brake facing width raising brake weight, the connection mode between brake facing 4 and the shoes 5 also changes machine riveting into together by bonding method.Improved the Joint strenght between brake facing and the shoes greatly, and when brake facing may wear to a certain degree, can take 6 in rivet apart and change brake facing and need not change by whole drg.Maintenance cost is the end very.Braking effect is remarkable, mature and reliable.
Because agricultural axle is mainly used in the place, farmland, requires low center of gravity, so carrying surface is wanted the end than spindle nose axis, the axis that then must central siphon and the axis of two spindle noses will have certain eccentric distance.The utility model carries out four sides processing to the connecting portion of spindle nose, and utilize the finished surface of connecting portion to be the contour of reference plane processing two bearings position with assurance spindle nose and connecting portion, and when welding, weld, so that the axis of two spindle noses and the parallel axes of carrying pipe with special tooling.
Because agricultural axle is mainly used in the place, farmland, maintenance point is less.So the service intervals cycle of agricultural axle is longer than common axletree.Between wheel hub 7 and the wheel hub cover 8 storage area is set in the utility model, makes the maintenance intervals of axletree longer than common axletree.
Though the utility model discloses as above with a preferred embodiment, be not in order to limit the scope that the utility model is implemented.Any those of ordinary skill in the art, in not breaking away from invention scope of the present utility model, when doing a little improvement, promptly every equal improvement of doing according to the utility model should be invention scope of the present utility model and contains.
