Abstract

The utility model discloses a penetrating shaft of a forced lubrication center bridge. The penetrating shaft comprises a shaft body, a shaft shoulder as well as a plurality of shaft heads and shaft necks which are used for mounting of gears or bearings, wherein an oil inlet channel which extends from the shaft head parts to the interior of the penetrating shaft is formed in the penetrating shaft along the axis direction of the penetrating shaft; the revolving surface of the penetrating shaft is provided with a plurality of oil holes which are formed towards the interior of the penetrating shaft from the revolving surface of the penetrating shaft; and the oil holes are communicated with the oil inlet channel. When the whole center bridge operates, lubricating oil can smoothly reach the oil holes 7 in the surface of the penetrating shaft through the oil inlet channel 5 inside the penetrating shaft and is conveyed to a contact part between each gear and the penetrating shaft through oil grooves 8 in the surface of the penetrating shaft, so that an oil film is formed when the gears and the penetrating shaft relatively move, and the frictional loss and heating are reduced to the maximum degree. According to the penetrating shaft, the optimal performance, compact structure and high reliability serve as design starting points.

Description

A kind of pressure lubrication jackshaft connects axle
Technical field
The utility model relates to automotive field, and specifically a kind of pressure lubrication jackshaft connects axle.
Background technique
This product mainly is in order to improve lubricated environment, the protection gear that jackshaft connects axle and associated gear.It is simple that traditional jackshaft connects axle construction, can only the implementation space arranges and finish the transmission lubricating function and then mainly rely on the lining of gear joint and bear.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved in the utility model is, provide a kind of optimization to lubricate environment, reduce noise, reduce the gear running temperature, improve the gear movement life-span, reduce parts depreciation, reduce the compacter pressure lubrication jackshaft of maintenance cost and structure and connect axle.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of pressure lubrication jackshaft connects axle, by axle body, the shaft shoulder and a plurality ofly form for spindle nose and axle journal that gear or bearing are installed, in connecting axle, be provided with from the spindle nose part to connecting the oil inlet passage that extends in the axle along the described axial direction that connects axle, be provided with a plurality of oilholes of offering to the oil inlet passage that connects in the axle from perforation axle turning surface at the turning surface that connects axle, described oilhole is communicated with oil inlet passage.
Above-mentioned pressure lubrication jackshaft connects axle, and the described turning surface that connects axle is provided with the oil groove that arranges along the axial direction spiral that connects axle, and described oil groove is connected with each oilhole.
Above-mentioned pressure lubrication jackshaft connects axle, and described oilhole is located between the spindle nose, between the axle journal or the joint between spindle nose and the axle journal.
Above-mentioned pressure lubrication jackshaft connects axle, and extension arranges described oilhole along the diametric(al) that connects axle to oil inlet passage.
The advantage that the utility model pressure lubrication jackshaft connects axle is:
1, optimize lubricated environment, reduce noise: the contacting point that jackshaft connects axle and interaxial differential and active cylindrical gears all can form the lubricating system of film lubrication-optimum when system motion, farthest optimized the lubricated environment of whole system, reduced parts depreciation and reduce noise.
2, reduce the gear running temperature, improve the gear movement life-span: lubricant oil can also be taken away a part of heat when the heat that optimum lubricating system makes motion produce reduced significantly, had reduced gear because crossing thermogenetic loss, had improved gear life.
3, reduce parts depreciation, reduce maintenance cost.
4, structure is compacter: this structure has been cancelled the many places lining, makes overall structure compacter.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial structurtes sectional view of A-A among Fig. 1.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, 2, a kind of pressure lubrication jackshaft connects axle, by axle body 1, the shaft shoulder 2 and a plurality ofly form for spindle nose 3 and axle journal 4 that gear or bearing are installed, in connecting axle, be provided with from spindle nose 3 parts to connecting the oil inlet passage 5 that extends in the axle along the axial direction that connects axle, be provided with a plurality of oilholes of offering to the oil inlet passage that connects in the axle from the turning surface 6 that connects axle 7 at the turning surface 6 that connects axle, oilhole 7 is communicated with oil inlet passage 5.For improving lubrication effect, 5 extensions arrange oilhole 7 along the diametric(al) that connects axle to oil inlet passage, and be provided with the oil groove 8 that arranges along the axial direction spiral that connects axle at the turning surface 6 that connects axle, oil groove 8 is connected with each oilhole 7, and oilhole 7 is located between the spindle nose 3, between the axle journal 4 or joint between spindle nose 3 and the axle journal 4.
The utility model is custom-designed for the lubricated environment that improves jackshaft perforation axle, interaxial differential and active cylindrical gears.For realizing this purpose of design, perforation axle of the present utility model has increased oil inlet passage 5 and the oilhole 7 of particular design three main positions, thereby carries out strong and effective lubricating to whole related system.Fundamentally solved and connected the axle lubrication problem, improved the gear mechanism movement environment, it is lubricated to replace lining.When bridge system moves in whole, lubricant oil can arrive the oilhole 7 that connects the axle surface smoothly and be sent to each gear and the perforation synapsis that is coupling by connecting the surperficial oil groove 8 of axle by connecting the inner oil inlet passage 5 of axle, make gear and connect axle and in relative movement, form oil film, farthest reduce friction loss and generate heat.The utility model adopts the oil inlet passage 5, oilhole 7 and the oil groove 8 that connect axle to realize gear and the film lubrication that connects between centers, is design starting point with optimal performance, compact structure, reliability height.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
