China's invention application 200810179000.7 discloses a kind of flexible coupling assembly that is used for electric motor driven power steering system and can comprise: coupling shell, and it is connected with motor reel; Worm shaft, the flange that its end that is included in this worm shaft forms; The coupling parts, it is arranged between coupling shell and the flange, and wherein the coupling parts are assemblied in the coupling shell, and rotatably are connected with the motor reel that in coupling shell, forms, and make coupling parts and coupling shell integral body rotate; And elastic protrusion part, its side from the coupling parts is whole outstanding.This coupler structure is too complicated, and damping effect is not good enough, and takes place easily to be shifted and to come off.
China's invention is applied for a patent 200520139961.7 and is disclosed a kind of coupling; Comprise left half-coupling, right half-coupling, the right side of left related axial organ is provided with the tooth bead, and right half-coupling left side is provided with the bead that is meshed with the tooth bead of the right side of left half-coupling; Be provided with outside thread in left half-coupling right part; Also have a nut, be enclosed within on the right half-coupling, match with the outside thread of left half-coupling right part.Equally, this coupler structure is also too complicated, and damping effect is not good enough, and takes place easily to be shifted and to come off.
Summary of the invention
The present invention solves the existing in prior technology technical problem, thus provide a kind of simple in structure, with low cost, damping effect is good and can effectively prevent the coupling that roller moves and the weaving roller that comes off is used.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of hitch bar; Described hitch bar comprises two tray joint shafts and is arranged on the link between the described tray joint shaft; Described tray joint shaft is fixedly connected through attachment screw; Described tray joint shaft is provided with the fastener hole of the rotating shaft that is used for fastening described roller, and described fastener hole matches with fastening screw trip bolt, and described link is a square thin slice; Described thin slice comprises the main perforate that is positioned at the central position; Four jiaos of described thin slice are provided with the secondary perforate that matches with described attachment screw, and the center of described tray joint shaft is provided with the engaging tooth that is meshed with the rotating shaft of described roller, and described engaging tooth comprises first engaging tooth and second engaging tooth.
As preferred embodiment of the present invention, the width of described first engaging tooth is greater than second engaging tooth.
As preferred embodiment of the present invention, the degree of depth of described first engaging tooth is greater than second engaging tooth.
Because hitch bar utilization of the present invention is arranged on the insulation rubber packing ring between the tray joint shaft, can strengthen the engaging force between the tray joint shaft on the one hand, can greatly reduce the vibration and the noise of whole coupling on the other hand.In addition, the design of two engaging tooths of tray joint shaft can effectively prevent the displacement of roller and come off.
