Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality The limitation of type.

The dynamical system 10 according to the utility model embodiment is described in detail below with reference to Fig. 1 and Fig. 2.

As depicted in figs. 1 and 2, included according to the dynamical system 10 of the utility model embodiment：Differential mechanism 1 and drive shaft 2, Differential mechanism 1 includes：Housing 11, housing 11 are arranged on the outside of differential mechanism 1, and such housing 11 can ensure the inside of differential mechanism 1 member Part will not be damaged by extraneous factor.

Wherein, as shown in figure 1, drive shaft 2 includes：Inner cages 21, Inner cages 21 pass through housing 11, moreover, Inner cages 21 Stretch into inside housing 11, also, as shown in Fig. 2 be provided with oil groove 3 at housing 11 and the cooperation position of Inner cages 21, so set Put oil groove 3, lubricating oil can flow in oil groove 3, lubricating oil can with effectively lubricating housing 11 and the cooperation position of Inner cages 21, It thereby may be ensured that and lubricated normally between differential mechanism 1 and drive shaft 2, be also possible to prevent to burn between differential mechanism 1 and drive shaft 2 Tie phenomenon.

Alternatively, oil groove 3 is formed on the internal perisporium of housing 11 and/or the periphery wall of Inner cages 21, it is understood that be, Oil groove 3 is individually formed on the periphery wall of Inner cages 21, either oil groove 3 be individually formed on the periphery wall of housing 11 or oil Groove 3 is formed on the periphery wall of Inner cages 21 and on the periphery wall of housing 11 simultaneously, can so be ensured in differential mechanism 1 and driving There is lubricating oil at any time between axle 2, moreover, being provided with oil simultaneously on the periphery wall of Inner cages 21 and on the periphery wall of housing 11 It groove 3, can also increase the area of oil groove 3, thereby may be ensured that the cooperation position good lubrication between differential mechanism 1 and drive shaft 2, It can also be better protected from sintering phenomenon occur between differential mechanism 1 and drive shaft 2.

Further, as shown in Fig. 2 oil groove 3 is formed in Inner cages 21, moreover, oil groove 3 is arranged to multiple, multiple oil Lubricating oil can be flowed into groove 3, so as to be effectively increased lubricants capacity between differential mechanism 1 and drive shaft 2, can so be carried Lubricant effect between high differential mechanism 1 and drive shaft 2, it can also further prevent from occurring between differential mechanism 1 and drive shaft 2 sintering now As occurring.

Specifically, oil groove 3 is obliquely installed on the periphery wall of Inner cages 21, moreover, oil groove 3 and the axis of Inner cages 21 press from both sides Angle is acute angle, and lubricating oil has mobility in the axis direction of Inner cages 21, so sets oil groove 3 to make lubricating oil in Inner balls Flow smooth on the axis direction of cage 21, thereby may be ensured that lubricant effect, differential mechanism 1 and drive shaft can also be better ensured that It is not in sintering phenomenon between 2.

Wherein, the axis direction of Inner cages 21 refers to left and right directions in Fig. 2.

Alternatively, the depth of multiple oil grooves 3 is identical, can so improve the structural stability of Inner cages 21, so as to Improve the structural stability of drive shaft 2.Moreover, the flow of lubrication of the multiple oil grooves 3 of depth identical is certain, thereby may be ensured that Lubricant effect between housing 11 and Inner cages 21, but also the waste of lubricating oil can be avoided to lose.

Further, the length of multiple oil grooves 3 is identical, can so ensure the structural integrity of oil groove 3, thereby may be ensured that The structural integrity of drive shaft 2.Moreover, upper shell 11 and Inner in the axial direction can be effectively ensured in the multiple oil grooves 3 of length identical Lubricant effect between cage 21, it can effectively prevent the generation of sintering phenomenon between differential mechanism 1 and drive shaft 2.

Specifically, the spacing between two adjacent oil grooves 3 is identical, so uniform in the perisporium finishing bathtray 3 of Inner cages 21 Distribution, moreover, oil groove 3 can ensure that the amount moment of lubricating oil between differential mechanism 1 and drive shaft 2 is identical, thereby may be ensured that The oil lubrication effect moment is identical, can also further prevent sintering phenomenon.In addition, spacing identical oil groove 3 can be with Ensure the structural reliability of Inner cages 21, it can also be ensured that lubricating oil continues and effectively lubricated between housing 11 and Inner cages 21 Cooperation position.

Alternatively, multiple oil grooves 3 be arranged in parallel, the structural integrity of Inner cages 21 can be so improved, so as to improve Fitness between drive shaft 2 and differential mechanism 1.

Further, oil groove 3 is in strip, because strip width is smaller, moreover, the width dimensions direction of oil groove 3 is set Put consistent with cage axial direction, so set oil groove 3 to increase the setting bar number of oil groove 3, so as to increase lubricating oil Into the amount of oil groove 3, and then it can preferably reach lubricant effect.
