Abstract
The utility model discloses an open type differential, which comprises a differential front shell and a differential rear shell. A cross axle is arranged between the differential front shell and the differential rear shell. The differential front shell and the differential rear shell are fastened together through hexagon socket head cap screws so as to fix the cross axle between the differential front shell and the differential rear shell. The end portions of the cross axle are respectively provided with a planetary gear. According to the utility model, the open type differential comprises a differential front shell, a differential rear shell, a cross axle and four planetary gears. The four planetary gears are arranged on the cross axle. The cross axle is positioned between the differential front shell and the differential rear shell. The differential front shell and the differential rear shell are fastened together through hexagon socket head cap screws so as to tightly fix the cross axle between the differential front shell and the differential rear shell. The thicknesses of the differential front shell and the differential rear shell are reduced in dimension, so that the cross axle and the planetary gears are exposed to the outside. Therefore, an open type structure is formed, wherein all components are in direct contact with the lubricating oil and are good in lubrication effect. Meanwhile, due to the adoption of the open type structure, the power transmission route is shortened, so that the transmission efficiency is improved.
Description
Technical field
The utility model relates to a kind of differential mechanism, especially relates to a kind of open differential, belongs to field of mechanical technique.
Background technique
Constantly perfect along with the national basis facility, the highway in China construction is maked rapid progress, and up to now, the highway in China total kilometrage has reached 3,700,000 kilometers, and wherein the expressway mileage open to traffic has reached 6.5 ten thousand kilometers, occupies the second place of the world.Highway transport vehicle forward large-tonnage, multiaxisization, high-power direction develop; Flatcar is a kind of common vehicle of highway transport, because large-scale, the heavy goods of its more convenient loading and unloading, and than other kinds vehicle of same size; Can load more goods, receive user's favor deeply.Along with the develop rapidly of domestic flatcar, flatcar is had higher requirement with ransaxle reliability and transmission efficiency.And at present the differential mechanism used of flatcar in use because lack of lubrication is more and more with the low Accident due to quality that occurs of reliability, so the functional reliability that need the raising differential mechanism and the intensity of differential casing.
The model utility content
To the deficiency that existing technology exists, the utility model technical problem to be solved is that a kind of open differential is provided; Solve the problem of differential mechanism lack of lubrication; Reduced rate of fault, the differential gear mission prolongs, and reaches the purpose of differential assembly life-span raising.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is; A kind of open differential comprises differential mechanism fore shell and differential mechanism back cover, is provided with cross axle between its differential mechanism fore shell and the back cover; Fastening between differential mechanism fore shell and the back cover through hexagon socket head cap screw, cross axle is fixed on middle; The shaft end of cross axle all is equipped with a planet gear.
Optimize, above-mentioned open differential, the thickness of its differential mechanism fore shell is reduced to 35-38mm.
Optimize, above-mentioned open differential, the thickness of its differential mechanism back cover is reduced to 28-32mm.
The utility model open differential comprises differential mechanism fore shell, differential mechanism back cover, cross axle and four planetary pinions, and four planetary pinions are installed on the cross axle, and cross axle is between the forward and backward shell of differential mechanism; The forward and backward shell of differential mechanism is fastening through hexagon socket head cap screw, in the middle of cross axle being fixed on tightly, through adopting the differential mechanism fore shell and the back cover of thickness dimension shrinks; Make outside cross axle and planetary pinion be exposed to, form Open architecture, all component all can directly contact with lubricant oil; Lubrication effect is very good, and this structure can shorten power transmission line, the raising transmission efficiency; On probation through actual entrucking, practical effect is very good.Through improving each link intensity, reach the purpose of differential assembly life-span raising.
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;
Fig. 2 be the utility model side view;
Fig. 3 is the blasting type structural representation of the utility model.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of open differential of the utility model comprises differential mechanism fore shell 1 and differential mechanism back cover 2, is provided with cross axle 3 between its differential mechanism fore shell 1 and the back cover 2; Fastening between differential mechanism fore shell 1 and the back cover 2 through hexagon socket head cap screw 4, cross axle 3 is fixed on middle; The shaft end of cross axle 3 all is equipped with a planet gear 5.The thickness of its differential mechanism fore shell 1 is reduced to 35-38mm.The thickness of its differential mechanism back cover 2 is reduced to 28-32mm.The utility model open differential is through adopting the differential mechanism fore shell and the back cover of thickness dimension shrinks, makes outside cross axle and planetary pinion be exposed to the formation Open architecture; All component all can directly contact with lubricant oil; Lubrication effect is very good, and this structure can shorten power transmission line, the raising transmission efficiency; On probation through actual entrucking, practical effect is very good.Through improving each link intensity, reach the purpose of differential assembly life-span raising.
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.
