Abstract
The utility model discloses an anti-loose structure of a motor steering tie rod. The structure comprises a steering gear rack, the steering tie rod and a locking gasket disposed between the steering gear rack and the steering tie rod, wherein the steering gear rack is provided with two milling flats, the locking gasket is provided with a square hole, the square hole is provided with two flangings which are disposed at one side of the locking gasket, the flangings are disposed at the outer sides of the milling flats and fit with the milling flats, the cross section of an end base of the steering tie rod is shaped like a regular hexagon and has six positioning planes, two opposite positioning planes staggered with the square hole of the locking gasket are planes positioning the bent portion of the locking gasket, and the bent portion of the locking gasket fits with the positioning planes. By using the structure provided by the utility model, the flangings at the square hole in the middle of the locking gasket is prevented from tilting and deforming when being pressed.
Description
Technical field
The utility model relates to the structure of auto parts and components, relates in particular a kind of horizontal drawing lever for car steering anti-loose structure.
Background technology
Steering gear rack and the tierod of automobile steering device are threaded connection, in order to prevent in use steering gear rack and tierod generation circumferential movement (being that tierod is loosening), be provided with locking gasket at steering gear rack and tierod junction, be provided with two flange on square hole and near a side of steering gear rack in the middle of the locking gasket, this flange is stuck on two milling flats relative on the steering gear rack end, thereby realizes the cooperation to steering gear rack.Relatively be provided with two plane of orientations on the sidewall of intermediate rod end seat, make the locking gasket of locking gasket and corresponding section, described plane of orientation position be bent to form kink to intermediate rod end seat by press-fiting locking gasket, the plane of orientation laminating of this kink and tie rod end, thus realization is to the cooperation of tierod.Because locking gasket has been realized respectively cooperation to steering gear rack and tierod having prevented relatively rotating of steering gear rack and tierod, thereby it is loosening to have avoided tierod to produce.
Due to two relative plane of orientations only being arranged on intermediate rod end seat in prior art, when press-fiting locking gasket, if the plane of orientation of intermediate rod end seat (namely with locking gasket by corresponding plane, position, splenium position) is in same direction with locking gasket third side hole flanging, during close together, press-fit the easy perk distortion of flange at rear middle square hole place, make locking gasket coordinate the place, location unreliable with steering gear rack, be difficult to guarantee the reliability that assembles.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal drawing lever for car steering anti-loose structure, and it can be avoided after locking gasket is press-fited, the flange perk at square hole place distortion in the middle of locking gasket.
Horizontal drawing lever for car steering anti-loose structure described in the utility model, comprise steering gear rack, tierod and the locking gasket between steering gear rack and tierod; The end of described steering gear rack is provided with two relative milling flats; Described locking gasket middle part offers square hole, and correspondence is provided with two flange on square hole, and two flange are positioned at a side of locking gasket; Steering gear rack is threaded with the end seat of tierod, steering gear rack, tierod and locking gasket are fitted tightly, described flange is positioned at the outside of described milling flat, and with milling flat, fit, the cross-sectional plane of the end seat of described tierod is regular hexagon, have six plane of orientations, two relative plane of orientations that wherein are staggered with locking gasket square hole place flange are the planes that are bent the location, folding part to locking gasket, locking gasket be bent folding part and described plane of orientation fits.
Horizontal drawing lever for car steering anti-loose structure described in the utility model, because the cross-sectional plane of the end seat of tierod is regular hexagon, namely this tierod has six plane of orientations, when locking gasket is press-fited, can select two relative planes that are staggered with locking gasket square hole place flange as locking gasket as by the splenium position, thereby actv. has been avoided the flange perk distortion at square hole place in the middle of locking gasket.

Fig. 2 is axonometric drawing of the present utility model;
Fig. 3 turns to the axonometric drawing of intermediate rod part in the utility model;
Fig. 4 is the axonometric drawing of locking gasket in the utility model;
Fig. 5 is the axonometric drawing of steering gear rack part in the utility model.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by coming by reference to the accompanying drawings.
To shown in Figure 5, this horizontal drawing lever for car steering anti-loose structure, comprise steering gear rack 1, tierod 2 and the locking gasket 3 between steering gear rack 1 and tierod 2 referring to Fig. 1; The end of described steering gear rack 1 is provided with relative milling flat a ' and milling flat b '; Described locking gasket 3 middle parts offer square hole, and correspondence is provided with flange a and flange b on square hole, and flange a and flange b are positioned at a side of locking gasket 3; The cross-sectional plane of the end seat 4 of described tierod 2 is regular hexagon, has six plane of orientations, comprises the first plane of orientation 41, the second plane of orientation 42, the 3rd plane of orientation 43, the 4th plane of orientation 44, the 5th plane of orientation 45 and the 6th plane of orientation 46; Steering gear rack 1 is threaded with the end seat 4 of tierod 2, steering gear rack 1, tierod 2 and locking gasket 3 are fitted tightly, described flange a and flange b are positioned at the outside of described milling flat a ' and milling flat b ', flange a and milling flat a ' laminating, flange b and milling flat b ' laminating.As can be seen from Figure 1, the first plane of orientation 41 and the 4th plane of orientation 44 on the other side from flange a, flange b away from, with be staggered from flange a, flange b, when press-fiting, select the first plane of orientation 41 and the 4th plane of orientation 44 to be the plane that is bent the location, folding part to locking gasket, after press-fiting, the kink of locking gasket and the first plane of orientation 41 and the 4th plane of orientation 44 fit, thereby have avoided flange a, the flange b perk distortion at the middle square hole place of locking gasket.
