Description

A kind of combined type differential spider

Technical field

Mechanical spare and accessory parts field is the utility model is related to, especially a kind of combined type differential spider.

Background technology

At present, the cross axle structure in automobile differential is mostly monoblock type, is primarily due to former differential design Limitation, mounting spherical of the planetary gear inside differential carrier respectively account for half inside two half-shells, and two half-shells are processed respectively Sphere, the differential carrier so processed, concentricity that two spheres are combined it is difficult to ensure that；This mode, which causes, to be added Work, transhipment, assembling inconvenience, reduce production efficiency, and after-sales service ensures difficult；If one on the differential spider Sub- axle is broken, and whole cross axle needs to carry out integral replacing, improves maintenance cost；

In view of this, the present inventor furthers investigate, and obtains a kind of combined type differential spider of this case then.

Utility model content

The purpose of this utility model is to provide a kind of a kind of simple in construction, easy-to-assemble combined type differential mechanism cross of appearance Axle.

In order to achieve the above object, technical scheme as the utility model use：

A kind of combined type differential spider, including four sub- axles of shape identical and the carrier block for carrying the sub- axle； The carrier block is in annular, and the carrier block is provided with four pieces of contiguous blocks, and the contiguous block is uniformly circumferentially positioned at described hold Carry the outer surface of block；The contiguous block be rectangle and on offer screwed hole；The sub- axle is in cylinder, and one end is free end The other end is connection end；The groove being connected on the contiguous block is offered on the connection end end of the sub- axle and is provided with and is available for Bolt passes through the through hole mutually locked with the screwed hole；The connection end of the sub- axle is in arc-shaped.

Further, the end of the contiguous block is provided with the first magnetic patch, and the bottom of the groove is provided with the second magnetic patch；It is described First magnetic patch is different in nature each other with the second magnetic patch.

Further, the groove madial wall is provided with one layer of rubber layer.

Further, described screw thread hole number is 2 and horizontal alignment is set；The quantity of the through hole also for 2 with The screwed hole is corresponding.

Further, the carrier block is integrally formed with the contiguous block.

By using above-mentioned technical proposal, the beneficial effects of the utility model are：

The novel and reasonable structure, compared with existing cross axle, solve the production difficulty of cross axle, existing cross axle For solid forging structure, high-precision position of related features is difficult to ensure that in process, easily causes the sintering of cross axle；Simultaneously When a certain sub- axle of cross axle damages, the increase that whole cross axle causes maintenance cost must be changed；The structure passes through Contiguous block on groove and carrier block on sub- axle cooperates, by bolt through the through hole on sub- axle, by sub- axle fixing lock Tightly on contiguous block；The connection end of sub- axle is in arc-shaped, can be preferably engaged with the carrier block of annular, reduces both it Between gap, every to be connected independently of each other between sub- axle and carrier block, certain sub- axle can be individually replaced when damaging, reduction Maintenance cost.

Embodiment

To make the purpose, technical scheme and advantage of utility model embodiment clearer, below in conjunction with the utility model Embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that described embodiment It is the utility model part of the embodiment, rather than whole embodiments.It is general based on the embodiment in the utility model, this area The every other embodiment that logical technical staff is obtained under the premise of creative work is not made, belong to the utility model guarantor The scope of shield.

As shown in Figure 1 to Figure 3, a kind of combined type differential spider, including the sub- axle 1 of four shape identicals and carrying The carrier block 2 of axle 1；Carrier block 2 is in annular, and carrier block 2 is provided with four pieces of contiguous blocks 21, and contiguous block 21 is uniformly circumferentially positioned at The outer surface of carrier block 2；Contiguous block 21 be rectangle and on offer screwed hole；Sub- axle 1 is in cylinder, and one end is free end 11 The other end is connection end 12；The groove 3 being connected on contiguous block 21 is offered on the end of connection end 12 of sub- axle 1 and is provided with and is available for Bolt 7 passes through the through hole 9 locked with the phase of screwed hole 8；The connection end 12 of sub- axle 1 is in arc-shaped；The novel and reasonable structure, it is and existing Cross axle compare, solve the production difficulty of cross axle, existing cross axle is solid forging structure, difficult in process To ensure high-precision position of related features, the sintering of cross axle is easily caused；Simultaneously when a certain sub- axle of cross axle damages When, the increase that whole cross axle causes maintenance cost must be changed；The structure passes through the company on the groove on sub- axle 1 and carrier block 2 Connect block 21 to cooperate, by bolt 7 through the through hole 9 on sub- axle 1, sub- axle 1 is fixed and lock onto on contiguous block 21；Sub- axle 1 Connection end 12 be in arc-shaped, can be preferably engaged with the carrier block 2 of annular, reduce gap between the two, each Connected independently of each other between sub- axle 1 and carrier block 2, certain sub- axle 1 can be individually replaced when damaging, and reduce maintenance cost.

Preferably, the end of contiguous block 21 is provided with the first magnetic patch 4, and the bottom of groove 3 is provided with the second magnetic patch 5；First magnetic patch 4 It is different in nature each other with the second magnetic patch 5；The design causes sub- axle 1 is easier connected with contiguous block 21 to be combined together, and passes through magnet The contiguous block 21 being assemblied on carrier block 2 that the attracting groove 3 made on sub- axle 1 is more prone to, while also cause both connections more Add firmly.

Preferably, the madial wall of groove 3 is provided with one layer of rubber layer 6；Prevent from producing using process neutron axle 1 and the collision of contiguous block 21 Raw infringement, causes scrapping for cross axle.

Preferably, the quantity of screwed hole 8 is 2 and horizontal alignment is set；The quantity of through hole 9 is also relative with screwed hole 8 for 2 Should；The fastness between sub- axle 1 and contiguous block 21 is further improved provided with two screwed holes 8.

Preferably, carrier block 2 is integrally formed with contiguous block 21；It is convenient to manufacture, while also strengthen contiguous block 21 with holding Carry the firmness between block 2.

Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality Example is applied the utility model is described in detail, it will be understood by those within the art that：It still can be to preceding State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic；And these Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and model of various embodiments of the utility model technical scheme Enclose.
