Abstract
The invention relates to a split type differential universal joint, and provides the split type differential universal joint which has the advantages of flexibility in installation, wide application range, and reduction of production and maintenance costs. The split type differential universal joint is characterized by comprising four sub shafts same in shape and a middle fixing block, wherein one end of each sub shaft is provided with a connecting part; the periphery of the middle fixing block is provided with connecting holes; the connecting part of each sub shaft is inserted and fixed in a connecting hole, thereby forming the differential universal joint. Preferably, the middle fixing block is square; oil flowing grooves are formed in the upper and lower surfaces of each sub shaft; when each sub shaft is connected together with the middle fixing block, the oil flowing grooves are respectively parallel to the upper and lower surfaces of the middle fixing block.
Description
Technical field
The present invention 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 former differential design restriction, the mounting spherical of planetary pinion inside differential carrier respectively accounts for half inside two and half shells, two and half shells process sphere respectively, the differential carrier processed like this, the very difficult guarantee of concentricity that two spheres are combined.This mode causes processing, transhipment, assembling inconvenience, and reduce manufacturing efficiency, after-sales service ensures difficulty.If the root axle on this differential spider ruptures, whole cross axle needs to carry out integral replacing, improves maintenance cost.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of flexible for installation, applied widely, reduce the split type differential spider of production, maintenance cost.
In order to solve the problem, this kind of split type differential spider, it is characterized in that comprising: fixed block in the middle of the sub-axle that four shapes are identical and, one end of every root axle has joint, the surrounding of this middle fixed block is provided with attachment hole, the joint of every root axle inserts and is fixed in an attachment hole, thus forms differential spider.
Preferably, described middle fixed block is square, and the upper and lower faces of described sub-axle was equipped with oil groove, and 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, be provided with four through holes above described middle fixed block, the joint of every root axle is provided with connecting through hole, and sub-axle is fastened on the sidewall of middle fixed block surrounding through through hole and connecting through hole by every root resilient key 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, and 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 invention has the beneficial effects as follows: this differential spider is split-type design, make this cross axle have stronger adaptability, corresponding differential carrier also must not adopt assembly to process again, decreases the expense of processing, transhipment, assembling; In addition, the differential carrier applying this kind of cross axle, need not whole set replacement when changing, and this considerably reduces the maintenance cost of user; 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 to process.In addition, in order to ensure 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 present invention;
Fig. 2 is the sectional structure schematic diagram of the split type differential spider in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As depicted in figs. 1 and 2, this kind of split type differential spider, comprise: fixed block 3 in the middle of the sub-axle 1 that four shapes are identical and, one end of every root axle has joint 11, this middle 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, thus forms differential spider.
This differential spider is split-type design, makes this cross axle have stronger adaptability, and corresponding differential carrier also must not adopt assembly to process again, decreases the expense of processing, transhipment, assembling; In addition, the differential carrier applying this kind of cross axle, need not whole set replacement when changing, and this considerably reduces the maintenance cost of user; 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 to process.In addition, in order to ensure overall structure steadiness, centre adds fixed block, makes this cross axle bulk strength constant.
In order to have lubrication object, strengthen lubrication effect, be equipped with oil groove 12 at the upper and lower faces of every sub-axle, 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.
Sub-axle in the present invention and can have between middle fixed block and be multiplely connected and fixed relation, such as: adopt pinned connection.Concrete: also comprise four resilient keys 2, above described middle fixed block 3 (or below) be provided with four through hole 3b, the joint 11 of every root axle is provided with connecting through hole 11b, and sub-axle is fastened on the sidewall of middle fixed block 3 surrounding through through hole 3b and connecting through hole 11b by every root resilient key 2 successively.In order to ensure that oil groove was parallel with middle fixed block, the aperture of the connecting through hole 11b on described every root axle was parallel with described mistake oil groove 12.
Also can there is thread connecting mode (not shown).Concrete: the attachment hole 3a on described middle fixed block 3 is tapped hole, and 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 explanation to technical solution of the present invention and explanation; should not be understood as the restriction to technical solution of the present invention, any employing technological scheme of the present invention and only do local change, must fall within the scope of protection of the present invention.
