Abstract
Disclosed is a drive axle main reducer shell assembly. The technical scheme includes that the drive axle main reducer shell assembly comprises a bearing seat and a main reducer shell, and the bearing seat and the main reducer shell are of an integral type structure. The drive axle main reducer shell assembly improves machining precision of a shell body and assembling efficiency of the main reducer shell assembly, greatly reduces the weight of the shell body, effectively removes the phenomena of oil leakage and oil seeping on the mating face of the main reducer shell and the bearing seat, and improves the use reliability of the main reducer shell.
Description
Technical field
The utility model is a kind of driving bridge main reducing housing assy, belongs to technical field of automobile parts.
Background technique
At present, the bearing support that uses on truck driving axle and master subtract shell and both be the part of absolute construction, and the assembling mode is: the bearing support that will be equipped with the little assembly of drive bevel gear subtracts shell by 6～10 stay bolts with the master and is connected.Need processing and be connected to connect seam and companion flange face, need to smear flat sealant between both junction plane during assembling, so not only increased cost of production, increased weight, also have the problem of possibility oil leak between junction plane both.
Key in herein technical field and describe paragraph.
Summary of the invention
The utility model provides a kind of technological scheme of driving bridge main reducing housing assy for the deficiencies in the prior art, and this programme has improved machining accuracy and the main efficiency of assembling that subtracts assembly of housing; Alleviated largely the weight of housing; Effectively eliminate the main phenomenon that subtracts shell and bearing support mating face oil leak, improved the main operational safety that subtracts shell.
The utility model is realized by following technical measures: a kind of driving bridge main reducing housing assy, comprise bearing support and the main shell that subtracts, it is the integral type structure that described bearing support and described master subtract shell, the bearing support of integral structure and described master subtract whole employing of shell and do not wait the wall thickness design, and wall thickness is mild transition between 4～8mm.
This isAccording to main stressing conditions and the support demand that subtracts housing assy.
Concrete characteristics of the present utility model also have, and are lubricating bearings better, and the bearing support corresponding place, driving pinion bearing housing hole of installing is provided with oil input channel and oil road, and described oil input channel and oil road and bearing support inner chamber consist of lubricating loop.
Concrete characteristics of the present utility model also have, and main subtracting is provided with the differential lock installation position on shell.Reserve the installing space of differential lock between wheel, only need to just process on housing when needing choosing dress differential lock and can realize above-mentioned functions.
The beneficial effects of the utility model are: the machining accuracy and the main efficiency of assembling that subtracts assembly that have improved housing; Alleviated largely the weight of housing; Effectively eliminate the main phenomenon that subtracts shell and bearing support mating face oil leak, improved the main operational safety that subtracts shell.
Description of drawings
Fig. 1 is the main structural representation that subtracts housing assy in background technique.
Fig. 2, Fig. 3 are the structural representation of the utility model embodiment.
Wherein: 1, bearing support, 2, the main shell that subtracts, 3, oil input channel, 4, oil road, 5, the differential lock installation position.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, this programme is set forth.
As accompanying drawing, a kind of driving bridge main reducing housing assy comprises bearing support 1 and the main shell 2 that subtracts, and described bearing support 1 and described master subtract shell 2 and be the integral type structure, the bearing support 1 of integral structure and described master subtract whole employing of shell 2 and do not wait the wall thickness design, and wall thickness is mild transition between 4～8mm.The corresponding place, driving pinion bearing housing hole of installing of bearing support 1 is provided with oil input channel 3 and oil road 4, and described oil input channel 3 and oil road 4 and bearing support 1 inner chamber consist of lubricating loop.Main subtracting also is provided with differential lock installation position 5 on shell 2.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (3)
1. driving bridge main reducing housing assy, comprise that bearing support and master subtract shell, it is characterized in that, it is the integral type structure that described bearing support and described master subtract shell, the bearing support of integral structure and described master subtract whole employing of shell and do not wait the wall thickness design, and wall thickness is mild transition between 4～8mm.
