Description
Technical field
The present invention relates to a kind of automobile component, particularly a kind of automobile main reducer assembly.
Background technique
Main gearbox assembly is the core part of ransaxle, and in the end of Power Train, its fundamental function is to increase the torque of being transmitted by transmission shaft or speed changer, reduces the rotating speed that it transmits, and power is reasonably distributed to left and right driving wheel.Main gearbox assembly is made up of retarder and differential mechanism, the retarder that present stage is used and the housing of differential mechanism are all split-type structural, it is complex process in assembly process, weight is large, and because bearing support and the housing point of retarder are arranged, easily produce the generation of oil leakage phenomenon, through extensively retrieval, not yet find comparatively desirable technological scheme.
Summary of the invention
The object of the invention is in order to solve present stage automobile main reducer set assembling technology complexity the shortcomings such as the easy leakage of oil of bearing support of money retarder, and a kind of automobile main reducer assembly proposing.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of automobile main reducer assembly, comprise retarder, differential mechanism is connected below retarder, described retarder comprises reducer shell, on reducer shell, be provided with bearing support, described differential mechanism comprises the first semiaxis housing and the second semiaxis housing of two corresponding matching), it is characterized in that:
A, described reducer shell and bearing support are overall structure;
B, described the first semiaxis housing and the second semiaxis housing are also overall structure.
On the basis of technique scheme, can there is following further technological scheme:
In differential casing, run through the planet pin that connects a yi word pattern, be socketed respectively a planetary pinion at the two ends of planet pin, two planetary pinions are all meshed with the differential gear on output axle shaft.
This device unites two into one the bearing support of retarder and housing, has the guide bearing chock of having cancelled retarder, simplifies product structure, has improved the work efficiency of product; Increase the diameter of input shaft simultaneously, and then increase main pinion and hold, improve main pinion life-span of holding.
The housing of differential mechanism is also by the original split type monolithic construction that makes into, and will originally connect planetary cross axle and change into the planet pin of a word, so alleviated the weight of product, improved again the efficiency of assembling of product.
The invention has the advantages that: this device has been simplified product structure and assembly technology, alleviated the weight of product, improved processing and the efficiency of assembling of product, improved oil duct simultaneously, improve lubricating efficiency, avoided the generation of the oil impregnate phenomenon of retarder, improved the working life of product.
