Abstract
The utility model relates to a bearing support in an automobile drive axle final drive assembly. The utility model provides a bearing support in the automobile drive axle final drive assembly, which is light, and is easy to assemble. According to the bearing support in the automobile drive axle final drive assembly, the bearing support is divided into an upper support body and a lower support body by a middle plate of the bearing support. The bearing support is characterized in that the middle plate has a petaloid outer shape; a connecting through hole is formed in each petal; a female end is formed in the outer wall of the upper support body, and extends to the middle plate; preferably, a built-in oil channel is formed in the cavity of the bearing support; the inlet end of the oil channel extends from the bottom of the middle plate to the inner wall on one side of the upper support body; the outlet end of the oil channel extends from the inner wall of the other side of the upper support body to the cavity of the lower support body; preferably, the plate part among three of the connecting through holes is widened; the inlet end of the built-in oil channel is arranged at the bottom of the widened part.
Description
Technical field
The utility model relates to a kind of improvement of bearing block structure, particularly the bearing support in a kind of automobile driving axle main gear box assembly.
Background technique
Vehicle is widely used in highway transport and engineering transportation, bearing support on automobile driving axle main gear box assembly is as the part that oil-way lubrication is played an important role, yet along with more and more lightweight and all need to install the equipment such as retarder of bevel housing, it is large that existing bearing support exists weight, is difficult for the defects such as assembling.And the oil duct arranging on bearing support is external oil duct, and asphalt channel plays key effect to bearing lubrication, affect oil consumption and the economic performance of car load.
Model utility content
For deficiency of the prior art, the utility model provide a kind of lightweight and be easier to assembling automobile driving axle main gear box assembly in bearing support.
In order to address the above problem, the bearing support in this kind of automobile driving axle main gear box assembly, the intermediate panel of this bearing support is divided into upper and lower two-part pedestal by bearing support, and the profile of described intermediate panel is petal, and each petal is provided with a connecting through hole; On the outer wall of upper pedestal, be provided with seam, this seam extends to intermediate panel.
Preferably, the inner chamber of this bearing support is provided with built-in oil duct, and the entrance point of this built-in oil duct is extended to by the bottom of intermediate panel on the inwall of a side of upper pedestal, and outlet end is extended in the cavity of lower base by the inwall of the opposite side of upper pedestal.
Preferably, the wherein card between three through holes in described connecting through hole is partly those widened sections, and the entrance point of described built-in oil duct is arranged on the bottom of this those widened sections.
More preferably, the external diameter of described lower base is: 170～180mm.
The utility model compared with prior art, has the following advantages:
1, the intermediate panel profile of bearing support of the present utility model is petal, has alleviated bearing support weight.
2, dwindle bearing support and final drive casing fitting surface diameter, weight is lighter.
3, bearing support of the present utility model is provided with seam, has met the requirement that retarder is installed, and is convenient to assembling.
4, bearing support of the present utility model arranges built-in oil duct, and oil circuit is more unobstructed, and lubrication effect is better.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of main gearbox assembly bearing support of the present utility model;
Fig. 2 is along the sectional structure schematic diagram of AA line in Fig. 1;
Fig. 3 is bearing support in the utility model and the connection diagram between bevel housing and retarder.
Part symbol description
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, bearing support in this kind of automobile driving axle main gear box assembly, the intermediate panel 1 of this bearing support is divided into upper and lower two-part pedestal by bearing support, be respectively upper pedestal 3 and lower base 2, lower base is connected with bevel housing by the ring through hole on intermediate disc, and the outer wall of upper pedestal is provided with a circle seam 31, and this seam extends downward intermediate panel 1 from outer wall middle part, meet the requirement that retarder is installed, be convenient to assembling.Card between two connecting through holes on this intermediate panel 1 partly narrows down, and makes the profile of this intermediate panel be petal, and each connecting through hole is arranged on each petal.The inner chamber of this external this bearing support is provided with built-in oil duct 4, the entrance point of this built-in oil duct starts to extend on a side inwall of upper pedestal by the bottom of intermediate panel 1, along bearing support housing inner chamber, extend to outlet end afterwards, outlet end is arranged on the inwall of upper pedestal opposite side, extends to subsequently in the cavity of lower base.In addition for the ease of oil duct import is set, the wherein card between three through holes part in this connecting through hole does not narrow down, thereby is formed with those widened sections 12 with respect to petal structure, and the entrance point of built-in oil duct 4 is arranged on the bottom of this those widened sections 12.In order to adapt to the bevel housing of new structure, the external diameter of this bearing support lower base is: 170～180mm.
As shown in Figure 3, bearing support of the present utility model is cast structure, its lubrication effect is better, lower base by the bearing support 5 that dwindles is connected with the fitting surface of final drive casing 6, this bearing support is provided with seam, is convenient to and retarder 7 assemblings, by designing the built-in oil duct 4 of new bearing support, can guarantee that oil circuit is more unobstructed, lubrication effect is better.
It should be noted that; embodiment is only to the explanation of technical solutions of the utility model and explanation; should not be understood as the restriction to technical solutions of the utility model; any employing the technical solution of the utility model and only do local change, must fall in protection domain of the present utility model.
