Abstract
The utility model provides a differential assembly used for the heavy driving axle, which comprises a differential housing, a cross shaft, half axle gears and planet gears. The cross shaft is arranged in the differential housing, the planet gears are arranged on four shaft journals of the cross shaft, the half axle gears are arranged at the upper part and the lower part of the differential housing, two half axle gears are both meshed with the four shaft journals of the cross shaft, bushes are arranged on the four shaft journals of the cross shaft, oil holes are arranged on the bushes, the back sides of the planet gears on the cross shaft are matched with the inner surface of the differential housing which is a spherical surface with diameter of 150 mm to 160 mm, and the diameter of the cross shaft is larger than 27 mm. The transmission torque of the differential assembly is large, thus the lubricating ability of the cross shaft is improved, and the agglomeration and fracture phenomena of the cross shaft are solved. The service life of the differential is enhanced. The differential assembly has the advantages that the bearing capacity is large and the aligning precision is higher, etc., and is suitable for the larger loading coupling and meets the requirement of the heavy vehicle.
Description
Technical field
The utility model relates to a kind of heavy-duty car component, particularly a kind of Heavy-Duty Drive-Axle differential assembly that is used for double drive axle.
Background technique
The differential assembly that the cargo vehicle double drive axle of domestic production is at present used, inner sphere radius is little, module is little, under heavily loaded situation, cause phenomenons such as gear fractures, sintering, ten sub-axle fractures easily, only be applicable to the occasion that load is lighter or medium, can not satisfy the usage requirement of heavy-duty car well.
Summary of the invention
The deficiency that the differential assembly that the utility model is used at existing cargo vehicle double drive axle exists provides that a kind of transmitting torque is big, the Heavy-Duty Drive-Axle differential assembly of long service life.
The utility model adopts following technical solution:
Heavy-Duty Drive-Axle comprises differential carrier, cross axle, differential gear and planetary pinion with differential assembly, cross axle is installed in the differential carrier, on four axle journals of cross axle planetary pinion is installed all, the differential carrier upper and lower all is equipped with differential gear, four planetary pinions on two differential gears and the cross axle all mesh, on four axle journals of cross axle lining is installed all, lining is provided with oilhole, the planetary back side on the cross axle and differential carrier internal surface are that the sphere of diameter 150mm to 160mm cooperates, and the cross axle diameter is greater than 27mm.
The utility model transmitting torque is big, has improved the cross axle lubricating ability, has solved cross axle sintering and phenomenon of rupture.Improved the working life of differential mechanism.Have characteristics such as bearing capacity is big, centering precision height, should be used for the bigger connection of load, satisfied assembling, the usage requirement of heavy-duty car.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, differential carrier top, 2, the differential gear pad, 3, differential gear, 4, the planetary pinion pad, 5, lining, 6, the lining back-up ring, 7, attachment bolt, 8, cross axle, 9, planetary pinion, 10, the differential carrier bottom, 11, differential gear.
Embodiment
As shown in drawings, Heavy-Duty Drive-Axle of the present utility model comprises differential carrier, cross axle 8, differential gear and planetary pinion 9 with differential assembly, cross axle 8 is installed in the differential carrier, and differential carrier is formed by a plurality of attachment bolts 7 connections by differential carrier top 1 and differential carrier bottom 10.Equal from inside to outside mounting bush back-up ring 6, lining 5, planetary pinion 9 and planetary pinion pad 4 on four semiaxis of cross axle 8, lining 5 is provided with oilhole, and the back side of planetary pinion 9 is that large diameter sphere cooperates with the differential carrier internal surface.Differential gear 3 is installed in the differential carrier top 1 by being installed in differential gear pad 2, and differential gear 11 is installed in the differential carrier bottom 10.Differential gear 3 in the differential carrier top 1 all mesh with four planetary pinions 9 on the cross axle 8, the interior differential gear 11 in differential carrier bottom 10 also with cross axle 8 on four planetary pinions 9 all mesh.Differential carrier connects with the automobile main reducer follower, and power is exported to ransaxle through differential carrier, cross axle, planetary pinion, differential gear, semiaxis successively from the main reducing gear driven gear.
The bulb diameter that the planetary pinion of the present utility model back side cooperates with the differential carrier internal surface strengthens than existing structure, and diameter is between the 150mm to 160mm; Planetary pinion 9 and differential gear 3 are more sturdy than existing, have improved the life-span.Also overstriking of cross axle 8, diameter be greater than 27mm, not easy-rupturing.Simultaneously on cross axle 8, increased copper lining 5, improved lubricated.
The utlity model has following characteristics:
1. the utility model has improved the transmitting torque of differential mechanism greatly, and increase the service life of differential mechanism.
2. the utlity model has big, the centering precision high of bearing capacity, should be used for the bigger connection of load, better biography Graduating power has satisfied assembling, the instructions for use of heavy-duty car.
3. improve the lubricated of differential mechanism, solved sintering phenomenon.
