Description
Technical field:
The utility model relates to engineering transport vehicle technical field, is a kind of integral type differential device specifically.
Background technique:
Along with developing of automobile industry, in, heavy truck enters high-speed development period, corresponding driving bridge demand also increases thereupon.In, the development trend of heavy-duty car is to develop to large-tonnage, high strength, high reliability direction, therefore at present the differential assembly that uses exists not enough: 1, cross shaft hole respectively with the semicircle orifice arranged in form on differential left/right shell, machining accuracy is difficult to guarantee; 2, interchangeablity is poor; 3, cost height.
Summary of the invention:
The purpose of this utility model is to have overcome the deficiencies in the prior art, and a kind of integral type differential device is provided, and has mainly solved problems such as differential casing machining accuracy and manufacture cost height, improves the intensity and the reliability of differential mechanism.
In order to achieve the above object, the utility model is achieved in that the integral type differential device, it comprises differential left shell 1 and differential right casing 2, its special way is that driven wheel of differential 3 connects by bolt-differential carrier 4 and differential left shell 1 and differential right casing 2, bearing-differential assembly 5 is established at two ends at differential left shell 1 and differential right casing 2 respectively, on differential right casing 2, establish cross shaft hole, in cross shaft hole, establish integral shaft 10 and segmentation axle 11, segmentation axle 11 connects with integral shaft 10, between differential left shell 1 and differential right casing 2, establish planetary pinion 6, packing ring-planetary pinion 7, differential gear 8 and packing ring-differential gear 9, differential gear 8 and planetary pinion 6 engagements, planetary pinion 6 connects with integral shaft 10 and segmentation axle 11, packing ring-planetary pinion 7 connects with planetary pinion 6, and packing ring-differential gear 9 connects with differential gear 8.
Integral type differential device of the present utility model, its described cross shaft hole is arranged on the differential right casing 2 with the circular hole form; Described integral shaft 10 and segmentation axle 11 fork-shapeds link together.
Compared with the prior art integral type differential device described in the utility model has following good effect: 1, integral shaft and segmentation axle are that split-type structural replaces former integrated type cross axle structure, integral shaft and segmentation yoke shape link together, carry out work with the cross axle form, compare the machining accuracy that is beneficial to a part with the integrated type cross axle, reduce difficulty of processing; 2, cost is low.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model integral type differential device in detail.
Integral type differential device described in the utility model, in the course of the work, the moment of torsion that motor provides is delivered to the driven wheel of differential that is engaged with by drive bevel gear, thereby driving differential carrier rotates, the integral shaft and the segmentation axle of the planetary pinion of differential carrier inside, differential gear and connection planetary pinion, differential gear rotate thereupon, gear wear is reduced in pad-planetary pinion and pad-differential gear adjusting gear gap.Also rotation thereupon of semiaxis by the flower bullock connects with differential gear transfers torque to wheel, and driving wheel is advanced.
When automobile turning, differential mechanism work, planetary pinion not only revolves round the sun around differential gear, and carries out rotation around its axle, and outside differential gear is accelerated, and inboard differential gear is slack-off, thus outboard wheels friction speed in making, so that realization is turned.
