Description
Technical field
The present invention relates to a kind of main reducing gear band differential assembly, belong to automobile making field of mechanical technique.
Background technology
The overwhelming majority is conventional two-piece structure (i.e. differential in the inter-wheel differential assembly used on existing commercial vehicle
Device housing assy is two parts of left differential carrier and right differential carrier composition), planetary gear shaft be that monoblock type appearance is in cross knot
Structure.
Left differential carrier and right differential carrier wherein in differential case assembly press the center of middle sphere to point, left and right
The sphere of part connects bolt with differential mechanism after being machined with the differential bearing mounting rod footpath at both ends and is fixed together reprocessing
Planetary gear shaft hole (hole of four angles in 90 °)；For ensure differential assembly state axle shaft gear with it is planetary just
Really engagement, the plane requirement that four planetary gear shaft centerline holes are formed is in the center of sphere.The major advantage of this structure
It is that structure design is simple, blank moulding process is ripe, production efficiency is high, and cost is low；But a disadvantage is that after the completion of mechanical processing very
The difficult accurate sphere for ensureing left housing and right shell can form an accurate sphere after component again, and (existing process is in left differential carrier
A hemisphere is processed on one hemisphere of upper processing, right differential carrier；Left and right shell is required to connect latter two hemisphere in theory
Should form a complete sphere four planetary gear installation positions), four planetary gear shaft hole centers are in technique
It is difficult to ensure that in sphere centre；Planetary gear shaft is a cross-shaped configuration：To ensure that it is opposite that normal use needs to ensure
The concentricity of two axis centers, it is two weeks adjacent between verticality error it is the smaller the better；But it is limited by heat treatment deformation and machinery
The limitation of processing technology, unmanageable and batch the uniformity of required geometric tolerance are also very poor.
If both sides hemisphere cannot form a complete sphere or planetary gear shaft hole not on the centre of sphere；Then or lead
Cause planetary gear abnormal with engaging for axle shaft gear, it may occur that gear ablation, planetary gear shaft and planetary gear sintering are one
Rise and cause there are the failures such as abnormal sound when planetary gear fracture, normally travel, can seriously cause differential mechanism failure to cause vehicle to be stopped transport.
On the other hand, the engine power of commercial vehicle is also constantly being lifted, to meet the requirement of the output torque of engine,
Correspondingly, require main reducing gear in drive axle to need Synchronous lifting with the moment of torsion that differential assembly can be born, to meet the requirements,
The intensity of active and passive gear secondary (driving gear+driven gear is known as active and passive gear pair) is most importantly lifted, is simply done
Method is exactly to increase the theoretical outside diameter of driven gear, but simply increases gear theory outside diameter, directly brings the upper of manufacture cost
Liter, the increase (unsprung mass for increasing vehicle) of assembly weight, occupancy chassis space increases, the passability of influence vehicle is (liftoff
Gap reduces) and a series of problems, such as the suspension arrangement of chassis.In addition, because main reducing gear band differential assembly is in actual use process
The load that middle left differential bearing and right differential bearing are born is different, and the design of traditional structure is simply left differential
Device bearing and right differential bearing are designed as same model, and (main cause is final drive casing, differential carrier blank moulding process
Simply, mechanical processing technique is convenient)；So left differential bearing can not be done with right differential bearing in actual use
To equivalent life, always the left differential bearing at the driven gear back side first damages, and virtually increases use cost and maintenance cost.
The content of the invention
The object of the present invention is to provide a kind of main reducing gear band differential assembly, solve in the prior art due to planetary gear
Center line intersection point it is misaligned with the centre of sphere of the spherical hollow space of differential carrier and cause planetary gear to be engaged not just with axle shaft gear
True technological deficiency.
To solve the above problems, the technical solution used in the present invention is：A kind of main reducing gear band differential assembly, including
Main gearbox assembly and inter-wheel differential assembly, the main gearbox assembly include final drive casing and drive bevel gear, institute

Shaft bevel gears and the center line of dynamic bevel gear overlap, and four are provided with the right differential carrier inside and outside right reducing gearbox
Shaft mounting hole, described four shaft mounting holes be located at two of spherical hollow space it is orthogonal diametrically, and four
The central axis of plane and dynamic bevel gear where shaft mounting hole, described four planetary gears are respectively by being arranged on
Shaft in shaft mounting hole is rotatably installed in spherical hollow space, and described four planetary gears are bored with left half axle at the same time
Gear and right axle shaft bevel gear are meshed, and the dynamic bevel gear is meshed with drive bevel gear.Left differential mechanism in the present invention
The interface of shell and right differential carrier is not located on planetary gear shaft mounting hole center, but takes the structure of deviation, this
Sample can be machined with inside right differential carrier single-piece a complete sphere while the processing of four planetary gear shaft holes with
Sphere is processed as clamped one time completion, can easily ensure very much that planetary gear shaft is installed according to existing process equipment level
Hole center and ball centre do not deviate, the concentricity of opposite two planetary shaft mounting holes, two neighboring planet tooth
The verticality of axle hole can ensure in claimed range, planetary center after being achieved in planetary gear installation is complete
The friendship of line is fallen to be placed exactly at the centre of sphere of spherical hollow space, ensures that planetary gear and engaging for axle shaft gear are normal, tooth will not occur
