Abstract
The utility model discloses a sealed differential device which comprises a differential device housing as well as a driven bevel gear and a cross axle that are fixed in the differential device housing, the axle end parts of the cross axle are respectively provided with a planetary gear, the differential device housing comprises a differential device front shell and a differential device rear shell, and the differential device front shell and the differential device rear shell have a sealed structure; and the differential device front shell and the driven bevel gear have an integral type structure. The sealed differential device is characterized in that the left shell and the right shell of the differential device are designed to be a sealed type, a sealing cover is arranged on the right shell, and in the throwing process, oil splashes onto the cover and then flows back into the differential devcie, so that the phenomenon that oil in the differential device sinters due to complete throwing can not happen. During design, the left shell of the differential device and the driven bevel gear are integrated into a whole, so that connecting bolts are reduced, the processing technology and the mounting technology are simplified, and the phenomenon that bolts for fastening the driven bevel gear are cut off due to over-large torque is avoided.
Description
Technical field
The utility model relates to a kind of differential mechanism, specifically relates to the sealed type differential mechanism that a kind of novel ransaxle is used, and belongs to mechanical field.
Background technique
Therefore automobile can need to install differential assembly for guaranteeing automobile drive axle both sides wheel with corresponding different rotating speeds rotation in the process of moving when stroke does not wait; Common differential mechanism is by differential mechanism fore shell, driven wheel of differential and connecting bolt, differential mechanism back cover, two differential gears; Four planetary pinions, a cross axle, four planetary pinion pads; The structural type of two differential gear pads is for guaranteeing the smoothness of lubricant oil in the differential mechanism, usually with holing on differential mechanism fore shell or the back cover; Oil in the differential mechanism is prone to throw away in the running; The differential mechanism internal cause oil that has all throws away and sintering phenomenon occurs, because the differential mechanism fore shell is connected with bolt with driven wheel of differential, very easily occurs causing the bolt cutting phenomenon too greatly because of moment of torsion.
The model utility content
To the deficiency that existing technology exists, the utility model technical problem to be solved is that a kind of sealed type differential mechanism is provided; Sealing is strong, and Safety performance is strong, and greasy property is strong; Differential left shell and driven wheel of differential are integrated; Reduced connecting bolt, simplified processing technology and mounting process, avoided causing fastening driven wheel of differential bolt cutting phenomenon too greatly because of moment of torsion.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is; A kind of sealed type differential mechanism comprises differential casing and the driven wheel of differential and the cross axle that are fixed in the differential casing, and the shaft end of cross axle is equipped with a planet gear; Its differential casing comprises differential mechanism fore shell and differential mechanism back cover, and differential mechanism fore shell and differential mechanism back cover are sealed construction; Said differential mechanism fore shell and driven wheel of differential are integral structure.
Optimize, above-mentioned sealed type differential mechanism, its differential mechanism back cover is provided with a seal closure.
The utility model sealed type differential design is differential mechanism left and right sides shell is designed to sealed type; On the right shell seal closure is housed; Be back to again in the differential mechanism after oil is splashed on the cover in the process of getting rid of, make the interior oil of differential mechanism can sintering phenomenon not occur because of all throwing away.During design differential left shell and driven wheel of differential are integrated, have reduced connecting bolt, simplified processing technology and mounting process, avoided causing fastening driven wheel of differential bolt cutting phenomenon too greatly because of moment of torsion.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model is a kind of sealed type differential mechanism; Comprise differential casing 1 and the driven wheel of differential 2 and cross axle 3 that are fixed in the differential casing 1; The shaft end of cross axle 3 is equipped with a planet gear 4, and its differential casing 1 comprises differential mechanism fore shell 11 and differential mechanism back cover 12, and differential mechanism fore shell 11 is a sealed construction with differential mechanism back cover 12; Said differential mechanism fore shell 11 is an integral structure with driven wheel of differential 2.Its differential mechanism back cover 12 is provided with a seal closure 5.The utility model sealed type differential design is differential mechanism left and right sides shell is designed to sealed type; On the right shell seal closure is housed; Be back to again in the differential mechanism after oil is splashed on the cover in the process of getting rid of, make the interior oil of differential mechanism can sintering phenomenon not occur because of all throwing away.During design differential left shell and driven wheel of differential are integrated, have reduced connecting bolt, simplified processing technology and mounting process, avoided causing fastening driven wheel of differential bolt cutting phenomenon too greatly because of moment of torsion.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
