Abstract
The utility model relates to a split differential spider. The split differential spider is easy to machine and install, wide in application range and low in production and maintenance cost. The split differential spider is characterized by comprising four auxiliary shafts which are identical in shape, one end of each auxiliary shaft is cut by a segment in the axial direction of the auxiliary shaft and forms a semicircular boss and a semi-groove corresponding to the boss. The boss of each auxiliary shaft is opposite to the semi-groove of another auxiliary shaft, and the four auxiliary shafts are spliced together to form the differential spider. Preferably, the four auxiliary shafts are equal in diameter, and the diameter of each auxiliary shaft is within a range of 30mm to 40mm. The utility model further relates to a differential which comprises a left differential shell, a right differential shell and the split differential spider.
Description
Technical field
The utility model relates to a kind of improvement of differential spider structure, particularly a kind of split type differential spider.The utility model also relates to a kind of differential mechanism that this kind of cross axle is installed.
Background technique
Existing differential mechanism comprises left and right differential carrier, and be arranged on the cross axle among this housing, as shown in Figure 1, differential spider structure of the prior art is all integrated type cross axle 5, such integrated type cross axle 5 is when assembling, can only adopt to have the mode that the left and right differential carrier 3,4 of corresponding cross shaft hole 31,41 is clamped described whole cross axle 5, cross shaft hole respectively accounts for half on left and right differential carrier.Thus, during mounting spherical at the processing cross shaft hole 31,41 of described left and right differential carrier 3,4 and planetary pinion in described differential carrier the inside, described left and right differential carrier must be connected on assembly and process with bolt, after machining, also need to beat pairing mark, thereby the cross shaft hole while guaranteeing assembling on left and right differential carrier is corresponding, and the concentricity that is combined of the planetary pinion mounting spherical that guarantees to process.This mode has caused processing, transhipment, assembling inconvenience, reduces manufacturing efficiency, and after-sales service ensures difficulty.If the root axle on this differential spider ruptures, whole cross axle need to carry out integral replacing, has improved maintenance cost.
Model utility content
For deficiency of the prior art, the utility model aims to provide a kind of processing, installs simply, applied widely, the split type differential spider produce, maintenance cost being low.
In order to address the above problem, this kind of split type differential spider, it is characterized in that comprising: four sub-axles that shape is identical, one end of every root axle axially cuts one section along it and forms a semi-circular boss, and half groove relative with this boss, the boss of every root axle is relative with half groove of another root axle, the four root axles formation differential spider that is stitched together.
Preferably, the equal diameters of described four root axles, all between 30～40mm.
The utility model also relates to a kind of differential mechanism, comprise left differential carrier, right differential carrier and differential spider, it is characterized in that: this cross axle is split type differential spider described above, on the sidewall of left differential mechanism or right differential carrier, be provided with four orthogonal through holes of hole axle, this differential spider is arranged in differential casing, and its sub-axle is through each through hole.
The beneficial effects of the utility model are: this differential spider is split-type design, make this cross axle have stronger adaptability, corresponding differential carrier must not adopt assembly processing more yet, have reduced the expense of processing, transhipment, assembling; In addition, apply the differential carrier of cross axle described in the utility model when changing, need not completely change, this has greatly reduced user's maintenance cost; Again on the one hand, cross axle structure of the present invention is simply easy to processing, does not need custom mold, directly adopts cylindrical bar processing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 2 and 3, this kind of split type differential spider, it comprises: four diameters, length and shapes are identical sub-axle all, and the diameter of four root axles is all between 30～40mm.One end of every root axle axially cuts one section along it and forms a semi-circular boss, and forms half groove relative with this boss.When combination is installed, two root axles 1,2 are first installed, half groove 11 on sub-axle 1 is relative with the boss 21 of sub-axle 2, according to this assembly relation, installs successively all the other two root axles, and final four root axles are stitched together mutually and form a complete differential spider.
The utility model also relates to a kind of differential mechanism, as shown in Figure 4, comprise left differential carrier 3 ', right differential carrier 4 ' and above-mentioned split type differential spider (not shown), on the sidewall of left differential mechanism or right differential carrier, be provided with four complete manholes 41 ' (take right differential carrier in figure as example), the hole axle of four through holes is mutually vertical, this differential spider is arranged in differential casing, and its every root axle is through a through hole.
Differential spider described in the utility model is split-type design, makes this cross axle have stronger adaptability, and assembly process and convenient only need to be by four minor axises of cross axle respectively through corresponding cross shaft hole on differential carrier; Corresponding differential carrier must not adopt assembly processing more yet, do not need supporting mark, has reduced the expense of processing, transhipment, assembling; In addition, apply the differential carrier of cross axle described in the utility model when changing, need not completely change, this has greatly reduced user's maintenance cost; Again on the one hand, cross axle structure of the present invention is simply easy to processing, does not need custom mold, directly adopts cylindrical bar processing.
