Abstract
The utility model discloses a universal coupler with a self-locking structure, which comprises a universal-joint fork (1), a universal-joint fork (2), a universal-joint sleeve (3), a universal-joint shaft (4), a universal-joint shaft sleeve (5), a universal-joint pin shaft (6) and a universal-joint fixed block (7). The universal coupler with the self-locking structure is characterized in that: the universal-joint shaft (4), the universal-joint shaft sleeve (5) and the universal-joint pin shaft (6) are locked into one body through the universal-joint fixed block (7); the universal-joint sleeve (3) leads the universal-joint fixed block (7) to be self-locked inside the universal-joint fork (1) and the universal-joint fork (2) to ensure that the outside of the universal-joint fork (1) and the universal-joint fork (2) has no bulge. The universal coupler with the self-locking structure has advantages of good synchronism and easy assembling/disassembling, increases reliability and synchronism of connecting of three sections of shafts for a passenger-car inner-swing door after being applied to the door shaft of the passenger-car inner-swing door, lowers the noise generated in the process of moving, and leads the installation and the maintenance of the three sections of shafts of the passenger-car door to be more convenient.
Description
One, technical field
The utility model relates to a kind of connection of universal-joint fork, the Hooks coupling universal coupling that has self-locking structure of a kind of novelty of more specifically saying so.
Two, background technique
Along with The development in society and economy, the passenger vehicle class is also along with lifting, and the Security of passenger door, aesthetic property and easy installation and maintenance become more and more important.The passenger vehicle structure of the front-mounted engine that adopts in the present passenger vehicle, the space that causes not installing straight door-hinge, what generally adopt now is the structure of three sections axles, it all is general universal joint that the connection between the universal-joint fork is adopted.Because it is asynchronous that the dimensional problem of universal-joint fork and universal joint causes the pivoted arm up and down of car door to rotate, to open at closing time, the bumpy motion of door-plate easily produces bigger impact force and noise.The Hooks coupling universal coupling that bus factory's employing at present connects three sections axles all is by being welded to connect on universal-joint fork basically.Because face of weld is smaller, passenger vehicle produces the door-hinge impact force very big again in the process of travelling, and often causes soldering point to come off, and produces security incident.Because the Placement that adopts is welding, installation property and maintainability are all very poor simultaneously.
Three, summary of the invention
1, goal of the invention
For solving problems such as the asynchronous and installation and maintenance inconvenience of size, rotation that present passenger vehicle universal-joint fork exists between connecting, the utility model provides a kind of Hooks coupling universal coupling with self-locking structure, both solve size and the nonsynchronous problem of rotation, solved the problem of installation and maintenance again.
2, technological scheme
A kind of Hooks coupling universal coupling that has self-locking structure, comprise universal-joint fork, universal-joint fork, joint boot, universal joint shaft, universal-joint sleeve, universal joint bearing pin, universal joint fixed block, it is characterized in that, is one by the universal joint fixed block with universal joint shaft, universal-joint sleeve and gudgeon of universal joint shaft locking, joint boot makes the universal joint fixed block be self-locking in universal-joint fork and universal-joint fork inside, guarantees the outside nothing projection of universal-joint fork and universal-joint fork.
Universal joint shaft is inserted in the universal joint fixed block after by universal-joint fork and joint boot.Universal-joint sleeve is inserted in the universal joint fixed block after by universal-joint fork and joint boot, then the universal joint shaft relative position is locked.The universal joint bearing pin is relative fastening by inserting behind universal-joint fork and the joint boot behind the universal-joint sleeve, and this fastening mode can be piercing and flanging, be threaded, glued joint, weld, sell modes such as connection and riveted joint.The universal joint fixed block is locked at universal-joint fork and universal-joint fork inside with joint boot, can't come off.
3, beneficial effect
The utility model provides a kind of Hooks coupling universal coupling that has self-locking structure, have advantages such as synchronism is good, easy installing/dismounting, reliability, synchronism that three sections axles of inner swinging door of passenger train connect can have been improved after being used in the connection of inner swinging door of passenger train door-hinge, reduced the noise in the movement process, made that the installation and maintenance of three sections axles of passenger vehicle door is more convenient.

Five, embodiment
Below in conjunction with accompanying drawing 1,2, specify mode of execution of the present utility model:
State shown in Figure 1 is whole part entirely knocked down states; As shown in Figure 3,4 joint boots (3) are assembled respectively in the hole in universal-joint fork (1) and the universal-joint fork (2), the bigger part of external diameter leans against the inwall of universal-joint fork (1) and universal-joint fork (2) in the joint boot (3), guarantees that like this joint boot (3) can't deviate from from the outside of universal-joint fork (1) and universal-joint fork (2); As shown in Figure 4, universal joint fixed block (7) is assembled to the centre of two joint boots (3), guarantees that joint boot (3) all can't deviate from from the outside and the inboard of universal-joint fork (1); As shown in Figure 5, universal joint shaft (4) is inserted in the hole of joint boot (3) and universal joint fixed block (7), and the groove in the middle of guaranteeing upwards; Hole alignment with universal-joint fork (2) and universal joint fixed block (7); In two universal-joint sleeves (5) insertion and the relatively-stationary joint boot of universal-joint fork (2) (3), the relative position of universal joint shaft (4) is locked by universal joint shaft (4) upper groove; As shown in Figure 6, the universal joint bearing pin (6) of packing into links together by piercing and flanging universal-joint fork (1) and universal-joint fork (2).As shown in Figure 2, be the utility model structural representation.
