Abstract
The utility model relates to a drive axle of a loader, which comprises an axle shell and a main transmission speed reduction mechanism. The main transmission speed reduction mechanism is arranged in the axle shell. Both left and right sides of the main transmission speed reduction mechanism are connected with bearings. The left bearing is connected with a wheel edge speed reducer and a caliper disc brake from left to right sequentially. The right bearing is connected with a caliper disc brake and a wheel edge speed reducer from right to left sequentially. After the drive axle is improved, the bearing capabilities of a wheel edge supporting axle and a wheel edge bearing are improved; the weld of the axle shell and the wheel edge supporting axle and the weld of the axle shell and a brake caliper supporting plate are difficult to fracture; and the fastening capability and an anti-shearing force of a wheel and the drive axle are strengthened.
Description
Technical field
The utility model relates to a kind of engineering truck drive axle, particularly a kind of loader drive axle.
Background technology
Drive axle is important composition parts in the industrial wheeled equipment driving system, must satisfy the job requirements of vehicle under various operating modes.Improving constantly along with the construction machinery and equipment overall performance in recent years, the particularly increase of engine power and output torque, and the raising of rotating speed during torque peak, the bearing load of drive axle is also in continuous increase, former 6 tons of loader drive axles also come out in the weak point of bearing aspect such as its load, are mainly reflected in: the load-carrying capacity deficiency of hub carrier and wheel limit bearing; The weld of the weld of hub carrier and axle housing and axle housing and brake clamp back plate is too approaching, and fracture appears in welding stress concentration easily; Because it is loosening that the continuous increase of drive torque, the rim nut of locking wheel and hub occur easily.
The utility model content
The purpose of this utility model is that a kind of adaptation loader present stage development need will be provided, load-carrying capacity is strong, bear that torque capability is good, transmission performance steadily, make things convenient for the loader drive axle of services and repairs.
The technical scheme of loader drive axle of the present utility model is as follows.
A kind of loader drive axle of the present utility model comprises axle housing, main gear speed reduction gearing, described main gear speed reduction gearing is arranged in the described axle housing, the left and right sides of described main gear speed reduction gearing all is connected with bearing, be connected with wheel reduction gear and caliper disk brake from left to right in turn on the bearing of described left side, described right side bearing is turned left from the right side and is connected with caliper disk brake and wheel reduction gear in turn.
Wherein, described wheel reduction gear comprises wheel limit pivot shaft, and described axle housing and the described limit pivot shaft of taking turns weld.
Wherein, described external diameter of taking turns the limit pivot shaft is 120-140mm.
Wherein, described external diameter of taking turns the limit pivot shaft is 130mm.
Wherein, described axle housing and described external diameter of taking turns limit pivot shaft connecting portion are 158-200mm, and internal diameter is 110-130mm.
Wherein, described axle housing and described external diameter of taking turns limit pivot shaft connecting portion are 180mm, and internal diameter is 120mm.
Wherein, described axle housing and described welding manner of taking turns between the pivot shaft of limit are the slope weldering.Be symmetrical arranged.
The beneficial effects of the utility model are as follows.
The beneficial effects of the utility model are that through the drive axle after improving, the load-carrying capacity of hub carrier and wheel limit bearing is improved; The weld of axle housing and hub carrier, brake clamp back plate is easy fracture not; The fastening ability and the anti-shearing force of wheel and drive axle are strengthened.
Description of drawings
Fig. 1 is a kind of loader drive axle of the present utility model part sectional view.
Among the figure: 1. axle housing 2. brake clamp back plates, 3. brake caliper assembly, 4. brake disc, 5. hub carrier, 6. oil sealing end cap, 7 rim nuts, 8. packing ring, 9. rim bolt, 10. nut, 11. hubs, 12. bearings, 13. packing rings, 14. oil sealings.
The specific embodiment
Below in conjunction with accompanying drawing a kind of loader drive axle of the present utility model is further specified.
As shown in Figure 1, it comprises axle housing 1, is connected with brake clamp back plate 2, brake disc 4 on the axle housing 1 and connects in axle housing 1 by brake clamp back plate 2.Axle housing 1 and described the wheel between 5 welding of limit pivot shaft, brake disc 4 and the wheel limit pivot shaft 5 are connected with oil sealing end cap 6 and oil sealing 15.Hub with the wheel between be connected by rim nut 7, packing ring 8, rim bolt 9, nut 10.
For axle housing 1 and hub carrier 5, strengthen the external profile diameter A and the inner edge diameter B (as Fig. 1) of joint, A is increased to 180mm by 158mm, and B is increased to 120mm by 110mm.
Strengthen the external diameter C (as Fig. 1) of hub carrier 5, be increased to 130mm by original diameter 120mm, and the corresponding tapered roller bearing 13 that adds the bull wheel limit, hub 11, oil sealing end cap 6, brake disc 4 etc., tapered roller bearing 13 is increased to 32026 by original 32024.
Shorten the length D of hub carrier 5,370mm shortens to 360mm by original length, and the position of weld that makes hub carrier 5 and axle housing 1 is side shifting outward, and the welded corner joint in axle housing 1 and brake clamp back plate 2 outsides is improved to chamfered welding.
Increase the quantity that hub connects rim bolt, be increased to 48 on a bridge by 24 on an original bridge.
After drive axle the problems referred to above are improved, the anti-twisting property of drive axle bolster has obtained the actv. raising, whole impact resistance and load-carrying capacity are strengthened, substantially hub carrier and axle housing weld fracture defect have been stopped, the easily loosening problem of rim nut is improved, and the drive axle after the improvement can satisfy the demand of 8 tons of loader operations under various bad working environments fully.
The above only is a preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
