Abstract

The utility model provides a synchronous retraction and expansion disk linkage device, comprising a plurality of retraction and expansion hooks and a transmission mechanism of the retraction and expansion hooks; wherein, the retraction and expansion hooks are arranged on a fixing member and can move in radial direction. The utility model is characterized in that the retraction and expansion hooks are arranged in a radial slideway on a disk; the top surface of the retraction and expansion hooks higher than the slideway is rack-shaped; a plurality of helical teeth on the bottom surface of an annular rotary disk are concentric with the disk and meshed with a rack on the top surface of the retraction and expansion hooks; a plurality of internal teeth are arranged in a round hole of the annular rotary disk; a drive gear above center of the disk is meshed with internal teeth of the annular rotary disk directly or via a planetary transition gear; a fixing claw hook is radially arranged on the edge of the disk at intervals with the moving retraction and expansion hooks. The utility model has the advantages of reasonable structure, light weight, simple operation, good synchronous effect and self-locking function.

Description

Linkage is received, expanded to disc type synchronously

Technical field

The utility model relates to that the control multiple spot shrinks to the center or expanded device, particularly is applicable to the device that outside steel rope tightens up in the vehicle limited slip device, is that linkage is received, expanded to a kind of disc type that multiple spot is radially moved synchronously specifically.

Background technology

In the existing linkage, as: outside steel rope tightening device is formed by being connected with the turnbuckle hook on the sum total draw ring by one in the vehicle limited slip device, each turnbuckle hook evenly is provided with, radially respectively with the vehicle limited slip device on the steel rope of the outside cooresponding attaching parts be connected.During installation, need to regulate each turnbuckle hook respectively, and the balance between the each point, the bad grasp of distance are difficult for making outside steel rope equilibrium to tighten up, operation inconvenience, efficient is low.

And the linkage that has is to be used in special occasions, and its accuracy requirement is very high, then because of reason such as complex structure, type heaviness, cost height, applicable surface be little, can't popularize.

Summary of the invention

The utility model is for overcoming the prior art shortcoming, providing a kind of disc type to receive, expand linkage synchronously.It is rational in infrastructure, moulding is light and handy, both artistic and practical, cost is lower, simple to operate, efficient is high, have certain auto-lock function.

The purpose of this utility model is achieved through the following technical solutions: a kind of disc type is received synchronously, expand linkage, comprise tightening up of being installed in that a plurality of on the same fixed parts move radially or expand hook and tighten up or expand the hook transmission device, it is characterized in that described tighten up or expand hook be contained in the radial groove that is provided with on the circular base plate, tightening up or expand the end face that hook exceeds chute is spline-simulating, have one with the concentric ring-type rotating disk bottom surface of circular base plate on helical tooth with tighten up or expand tooth bar engagement on the hook end face, circular hole is provided with internal tooth in the middle of the ring-type rotating disk, has one to be contained in driving gear above the circular base plate center of circle directly or by planet transition gear and ring-type rotating disk internal gearing.

Described circular base plate is provided with fixedly claw hook on the edge, and evenly is provided with at interval with mobile tightening up or expand hook.

Have a deckboard and circular base plate to fasten on the described ring-type rotating disk, the rotating shaft two ends of planet transition gear are connected with circular base plate with deckboard respectively.

Described deckboard is a disc, has in the middle of it to expose the circular hole that endoporus is rotated at the driving gear center, and periphery has and exposes fixedly claw hook and the breach and and the circular base plate bonded assembly screw hole that tighten up or expand hook.

The utility model compared with prior art has many advantages and good effect:

1, rational in infrastructure, moulding is light and handy, cost is lower, of many uses.

2, only rotate parts, promptly the center of turn driving gear just can make the radially same moved further of multiple spot, and simple to operate, synchronous effect is good, the efficient height, and have certain auto-lock function.

3, Pei Zhi deckboard is both artistic and practical, is specially adapted to luxury car etc.

The specific embodiment

Referring to Fig. 1-Fig. 5, linkage is received, expanded to a kind of disc type synchronously, have on the edge of a circular base plate 43 fixedly claw hooks 1 are set, also have 3 to tighten up or expand hook 7 and be contained in 3 radial grooves 8 that are provided with on the circular base plate 4, fixedly claw hook 1 with tighten up or expand evenly radially settings at interval of hook 7.Tightening up or expand the end face that hook 7 exceeds chute 8 is spline-simulating, have one with concentric ring-type rotating disk 3 bottom surfaces of circular base plate 4 on helical tooth 9 with tighten up or expand tooth bar engagement on hook 7 end faces, circular holes are provided with internal tooth in the middle of the ring-type rotating disk 3, have one with the concentric center driving gear 5 of circular base plate 4 by 3 planet transition gears 6 and ring-type rotating disk 3 internal gearings.There are a disc deckboard 2 and circular base plate 4 to fasten on the described ring-type rotating disk 3, have in the middle of the deckboard 2 and expose the circular hole 10 that endoporus is rotated at driving gear 5 centers, periphery have expose fixing claw hook 1 and tighten up or expand hook 7 breach 11 and with circular base plate bonded assembly screw hole, and connect by screw.The rotating shaft two ends of three planet transition gears 6 are connected with circular base plate 4 with deckboard 2 respectively.

Referring to Fig. 6, when the utility model linkage is used in the vehicle limited slip device, claw hook 1 and tighten up hook 7 and evenly hang on the steel rope 12 of the vehicle limited slip device outside is fixed, with rotating in the spanner insertion driving gear center rotation endoporus, driving gear drives three planet transition gears 6 and ring-type rotating disk 3 rotates, it is that the hook 7 that tightens up of spline-simulating shrinks to the center that ring-type rotating disk 3 makes end face by the helical tooth on its bottom surface 9, with steel rope 12 tensions of the vehicle limited slip device outside, the vehicle limited slip device is fastened on tire 13 crowns.

The utility model not only can be used for the vehicle limited slip device, also can be used for the multiple occasion that other need multiple spot to tighten up synchronously or expand.
