Abstract
The utility model relates to a split type differential spider which can be installed flexibly, has wide application range, and lowered production and maintenance cost. The split type differential spider is characterized by comprising four secondary spindles with the same shape and a middle fixing block, wherein one end of each secondary spindle is provided with a connecting part, connecting holes are formed in the periphery of the middle fixing block, and the connecting part of each secondary spindle is inserted and fixed in one connecting hole so as to form the differential spider. Preferably, the middle fixing block is square, oil grooves are respectively formed in the upper and lower surfaces of the secondary spindles, when the secondary spindles and the middle fixing block are connected, the oil grooves are respectively parallel to the upper and lower surfaces of the middle fixing block.
Description
Technical field
The utility model relates to a kind of improvement of differential spider structure, particularly a kind of split type differential spider.
Background technique
At present, cross axle structure in automobile differential mostly is all-in-one-piece, mainly because the restriction of former differential design, planetary pinion respectively accounts for half at the mounting spherical of differential carrier the inside in two and half shell the insides, two and half shells are processed respectively sphere, the differential carrier processing like this, two very difficult assurances of concentricity that sphere is combined.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, it is a kind of flexible for installation, applied widely that the utility model provides, and reduces the split type differential spider of production, maintenance cost.
In order to address the above problem, this kind of split type differential spider, it is characterized in that comprising: four sub-axle and middle fixed blocks that shape is identical, one end of every root axle has joint, the surrounding of this centre fixed block is provided with attachment hole, the joint of every root axle inserts and is fixed in an attachment hole, thereby forms differential spider.
Preferably, described in the middle of fixed block be square, the upper and lower faces of described sub-axle was equipped with oil groove, when each sub-axle and middle fixed block link together, it is parallel with the above and below of middle fixed block respectively that this crosses oil groove.
Preferably, also comprise four resilient keys, above described middle fixed block, be provided with four through holes, the joint of every root axle is provided with connecting through hole, and every resilient key is fastened on sub-axle on the sidewall of middle fixed block surrounding through through hole and connecting through hole successively.More preferably, the aperture of the connecting through hole on described every root axle is parallel with described mistake oil groove.
Preferably, the attachment hole on described middle fixed block is tapped hole, on the joint of described sub-axle, is processed with outside thread, and the joint of every root axle screws in and is fixed in attachment 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 this kind of cross axle when changing, need not completely change, this has greatly reduced user's maintenance cost; Again on the one hand, cross axle structure described in the utility model is simply easy to processing, does not need custom mold, directly adopts cylindrical bar processing.In addition, in order to guarantee overall structure steadiness, centre adds fixed block, makes this cross axle bulk strength constant.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of the split type differential spider in the utility model;
Fig. 2 is the sectional structure schematic diagram of the split type differential spider in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this kind of split type differential spider, comprise: four sub-axle 1 and middle fixed blocks 3 that shape is identical, one end of every root axle has joint 11, this centre fixed block 3 is preferably square, its surrounding sidewall is provided with four attachment hole 3a, and the joint of every root axle inserts and is fixed in an attachment hole, thereby forms differential spider.
This differential spider is split-type design, makes this cross axle have stronger adaptability, corresponding differential carrier must not adopt assembly processing more yet, has reduced the expense of processing, transhipment, assembling; In addition, apply the differential carrier of this kind of cross axle when changing, need not completely change, this has greatly reduced user's maintenance cost; Again on the one hand, cross axle structure described in the utility model is simply easy to processing, does not need custom mold, directly adopts cylindrical bar processing.In addition, in order to guarantee overall structure steadiness, centre adds fixed block, makes this cross axle bulk strength constant.
In order to there is lubricated object, strengthen lubrication effect, at the upper and lower faces of every sub-axle, be equipped with oil groove 12, when each sub-axle and middle fixed block link together, it is parallel with the above and below of middle fixed block 3 respectively that this crosses oil groove 12.
Between sub-axle in the utility model and middle fixed block, can there is the multiple relation that is connected and fixed, for example: adopt bearing pin to connect.Concrete: also comprise four resilient keys 2, above described middle fixed block 3, (or below) is provided with four through hole 3b, the joint 11 of every root axle is provided with connecting through hole 11b, and every resilient key 2 is fastened on sub-axle on the sidewall of middle fixed block 3 surroundings through through hole 3b and connecting through hole 11b successively.Parallel with middle fixed block in order to guarantee oil groove, the aperture of the connecting through hole 11b on described every root axle is parallel with described mistake oil groove 12.
Also can there is thread connecting mode (not shown).Concrete: the attachment hole 3a in the middle of described on fixed block 3 is tapped hole, on the joint 11 of described sub-axle, is processed with outside thread, and the joint of every root axle screws in and is fixed in attachment hole.
It should be noted that; embodiment is only to the explanation of technical solutions of the utility model and explanation; should not be understood as the restriction to technical solutions of the utility model; any employing the technical solution of the utility model and only do local change, must fall in protection domain of the present utility model.
