Sign can be combined with each other.
The utility model is described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
The utility model provides a kind of stabiliser bar connection structure, which includes stabiliser bar 10, connecting rod
20 and nut 30, the end of the stabiliser bar 10 is provided with connector 11, and the connector 11 has tapped through hole, the connection
The end of bar 20 is provided with ball pin, and the outside wall surface of the ball pin bar 21 of the ball pin is formed with screw thread and is threadedly coupled in the screw thread
Through-hole, the nut 30 are threadedly connected to the part for being pierced by the tapped through hole of the ball pin bar 21.
As depicted in figs. 1 and 2, the end of connecting rod 20 is provided with ball pin, usually by being welded to connect ball pin and connecting rod
20, screw thread is formed on the ball pin bar 21 of ball pin, the tapped through hole that ball pin bar 21 is threadedly coupled on connector 11 is simultaneously pierced by the spiral shell
Line through-hole, screw thread 30 are threaded in being pierced by the part of the tapped through hole of ball pin bar 21, therefore the screw thread simultaneously of ball pin bar 21
Connector 11 and nut 30 are connected, by this connection structure, even if vehicle encounters contingent situation and nut is caused to loosen, ball pin bar
It remains as and is threadedly coupled with the connector of stabiliser bar, provide second protection for connection, effectively prevent safety accident.
With reference to the structure of Fig. 3 and Fig. 4, it is provided in circle convex platform 12 and the connector 11 and is formed on the connector 11
Have circular hole, screw thread be formed in circular hole, be likewise formed on the inner wall of circle convex platform 12 screw thread and with the spiral shell that is formed in circular hole
Line matches, therefore the tapped through hole is limited jointly by circle convex platform 12 and circular hole, and in the outside wall surface of circle convex platform 12
It is provided with screw thread, so that nut 30 is threadedly connected to the portion for being pierced by the circle convex platform 12 of circle convex platform 12 and ball pin bar 21 simultaneously
Point, to improve the bonding strength between connecting rod and stabiliser bar.
Specifically, with reference to structure shown in Fig. 7, nut 30 has upper nut through-hole 31 and lower nuts through-hole 32, institute
The part for being pierced by the tapped through hole that upper nut through-hole 31 is threadedly connected to the ball pin bar 21 is stated, wherein upper nut is logical
The internal diameter in hole 31 is less than the internal diameter of lower nuts through-hole 32.
With reference to Fig. 5 and structure shown in fig. 6, ball pin bar 21 includes the first bar portion 211 and is connected to first bar portion 211
The second bar portion 212, the diameter of first bar portion 211 is greater than the diameter of second bar portion 212, first bar portion 211
Outside wall surface on and the outside wall surface of second bar portion 212 be respectively formed on screw thread, top tapped through hole 31 is threadedly coupled second
Bar portion 212, lower nuts through-hole 32 is threadedly coupled the first bar portion 211, due to the screw thread of second bar portion 212 and described first
The screw thread of bar portion 211 it is oppositely oriented so that the threaded connection between ball pin bar and connector is in the direction opposite ball pin bar and spiral shell
Threaded connection direction between mother prevents from connecting to effectively increase the bonding strength between connecting rod and stabiliser bar
It loosens and misplaces.
It should be noted that first bar portion 211 and second bar portion 212 oppositely oriented for matching thread, then nut 30
Top tapped through hole 31 and connector 11 tapped through hole thread rotary orientation conversely, because lower thread through-hole 32 be threadedly coupled
In the outside wall surface of circle convex platform 12, in screw on nut 30, the outside wall surface screw thread of lower nuts through-hole 32 and circle convex platform 12 connects
It while connecing, is also threadedly coupled between top tapped through hole 31 and the second bar portion 212, therefore lower nuts through-hole 32 and top spiral shell
The thread rotary orientation of female through-hole 31 should be identical, to guarantee smoothly to screw.
Conclude it is above-mentioned, the second bar portion 212, upper nut through-hole 32, lower nuts through-hole 31 and circle convex platform 12 outer wall
The rotation direction of screw thread on face is identical and one of selects left-handed and dextrorotation, the tapped through hole of connector 11 and the first bar portion 211
Screw thread rotation direction it is identical and the other of select left-handed and dextrorotation.
Wherein, in order to enable the connection of nut 30 is more firm, in the lower thread through-hole 32 and circle convex platform 12 of nut
Outside wall surface be threadedly coupled in the state of, the end face of nut press on connector 11 surface and nut upper nut it is logical
In the state that hole 31 is threadedly coupled with the second bar portion 212, the end face of upper nut through-hole 31 presses on the end face of circle convex platform 12.
With reference to structure shown in Fig. 4, since the tapped through hole is limited jointly by the circular hole in circle convex platform 12 and connector
Fixed, in order to improve the reliability of tapped through hole, circle convex platform 12 and connector 11 are integrally formed part, for example can pass through punching press
Molding mode is cast.
In addition, being used for for the ease of stable connection bar and connecting rod as shown in figure 5, being formed on the end face of ball pin bar 21
The handle hole 213 of attended operation tool, the handle hole 213 can be Hexagon hole, and allen wrench can be used in operator will
Ball pin bar is threadedly connected in the tapped through hole on connector 11.Specifically, stable connection bar and the step of connecting rod include: by
The first bar portion of ball pin bar 211 is threadedly connected to the tapped through hole in connector 11, and mounting means is to be cooperated by allen wrench
First bar portion 211 and tapped through hole are fastened in handle hole 213；It is convex that nut 30 is threadedly connected to annulus simultaneously later
