The connection mode of the rear transverse arm of prior art and rear-axle steering joint is: as shown in Figure 1, the body of rear-axle steering joint 1 offers through hole, the inner tapping of through hole forms female thread structure, the end of rear transverse arm 3 and prenex adjust bar 2 is provided with the screw 5 of corresponding negative thread, screw 5 is rotatably vertically connected at rear transverse arm 3 and prenex adjust bar 2 end, screw 5 and be provided with a circle rubber pad between rear transverse arm 3 and prenex adjust bar 2, by screwing screw 5 by the installation of transverse arm 3 after can completing in the through hole be fixed on rear-axle steering joint 1 and prenex adjust bar 2.Such Installation Modes structure is simple and convenient, but during practical application, rear transverse arm 3 and prenex adjust bar 2 stressed time can pulling force or pressure be delivered on steering swivel, and perforate is stressed weak location on back axle steering swivel 1, easily deformation is there is time stressed, cause the damage of parts, thus affect the use of whole automobile.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of prenex adjust bar and rear transverse arm and rear-axle steering to save connection structure.
The technical solution of the utility model is: a kind of prenex adjust bar and rear transverse arm and rear-axle steering save connection structure, comprises rear-axle steering joint, prenex adjust bar and rear transverse arm; Described rear-axle steering joint offers through hole; Described prenex adjust bar and the end of rear transverse arm are provided with corresponding with through hole and with externally threaded fix screw, it is characterized in that: be provided with bolt in described through hole; Described bolt comprises the fixed cover being arranged in and being fixedly connected with through hole in through hole; Described fixed cover hollow is provided with the negative thread corresponding with the outside thread on screw inside it; Described screw passes fixed cover and screw thread is fixedly connected with it.
Further described bolt also comprises the head being fixed on fixed cover end; Described head diameter is greater than the internal diameter of through hole; Described screw is fixed in bolt through fixed cover and head successively.
Further described fixed cover is arranged in through hole and is connected with through hole interference fit outside it.
Further described head is fitted on rear-axle steering joint.
Advantage of the present utility model has: 1, the utility model replaces the through-hole structure of internal tapping by the bolt arrangement arranging hollow, increase rear transverse arm, prenex adjust bar and rear steering save between linking intensity, make structure more firm, firm, also can select the bolt of different brackets simultaneously according to different requirement of strength, improve the commonality of rear steering joint;
2, the utility model arrange hollow bolt easy for installation, by press-in mode and Absorbable organic halogens will be bolted in through hole easily, assembling process is convenient and swift, reduce rear transverse arm and prenex adjust bar installation difficulty;
3, the utility model structure is simple, easy for installation, and after solving tapping, the removing of burr difficulty and conventional mounting mode easily damage the problem of rear-axle steering joint, have great promotional value.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 2 ~ 4, the rear-axle steering joint structure of the present embodiment, comprise rear-axle steering joint 1, prenex adjust bar 2 and rear transverse arm 3, rear-axle steering joint 1 offers through hole 4, the end of prenex adjust bar 2 and rear transverse arm 3 is provided with corresponding with through hole 4 and with externally threaded fix screw 5, be provided with a circle rubber pad between the end of screw 5 and prenex adjust bar 2 and rear transverse arm 3, screw 5 is rotatably articulated and connected the end in prenex adjust bar 2 and rear transverse arm 3.
As shown in figs. 34, bolt 6 is provided with in through hole 4, bolt 6 comprises the fixed cover 6 being arranged in and being fixedly connected with through hole 4 in through hole 4, fixed cover 6 hollow is provided with the negative thread corresponding with the outside thread on screw 5 inside it, and the end of fixed cover 6 is provided with the head 7 of hollow, and head 7 is communicated with fixed cover 6, the diameter of head 7 is greater than the internal diameter of through hole 4, such setting, when fixed cover 6 is subject to the pulling force along its axis, can avoid fixed cover 6 to deviate from from through hole 4.
