The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation of not doing opposite explanation, the noun of locality of use is such as " left and right " when typically referring to Vehicle Driving Cycle, actual turn direction to the left or to the right, and " forward and backward " refers to forward and backward with respect to vehicle heading.
Referring to Fig. 2, the utility model relates to a kind of steering swivel position limiting structure, and this steering swivel position limiting structure comprises the steering swivel 1 that is installed on the axletree 2, and more specifically, steering swivel 1 is hingedly mounted on the axletree 2.Be provided with limiting section at axletree 2.As previously mentioned, in the prior art, by steering swivel outer corner measurement cubing the installation process of screw on steering swivel 1 detected, more particularly, detect the height of the outstanding steering swivel 1 of screw, after the height of the outstanding steering swivel 1 of screw is in predetermined altitude, by jam nut 17 fix screws.This one by one method of debugging has reduced the installation effectiveness of screw.
In order to address the above problem, the utility model is provided with locating part 15 in the fork-shaped section 10 of steering swivel 1, this locating part 15 forms predetermined length from the length that this fork-shaped section 10 protrudes under installing condition, thereby the end of locating part 15 contacts with limiting section when steering swivel 1 reaches predetermined hard-over.Wherein, limiting section is restriction protrusion 21 in the present embodiment, but is not limited to the restriction protrusion 21 shown in the figure.The predetermined length of locating part 15 can draw by the test of precision.
Be appreciated that after determining the predetermined length of locating part 15, no longer need locating part 15 is debugged one by one, can directly locating part 15 be installed on the steering swivel 1, thereby improved the installation effectiveness of locating part 15.And the predetermined length of locating part 15 can be accomplished in several ways.
For example, as shown in Figure 2, locating part 15 comprises stop screw 15a and stop collar 15b, be formed with tapped bore 14 in the fork-shaped section 10, stop screw 15a passes stop collar 15b and is fastened in the tapped bore 14, the screw head of stop screw 15a is pressed against on the end face of stop collar 15b, and predetermined length is the thickness sum of axial length and the screw head of stop collar 15b.In the structure of this locating part 15, as long as after determining predetermined length by test, more specifically, determine the length of stop collar 15b after, can Fast Installation stop screw 15a.Because use the stop collar 15b of equal length, for the different vehicle of same vehicle, the control of its hard-over has higher conformability.In addition, owing to do not need steering swivel outer corner measurement cubing that stop screw 15a is detected repeatedly, both improve the installation effectiveness of locating part 15, reduced again the cost of installation that uses steering swivel outer corner measurement cubing.And, after the stop screw 15a installation, axially be subject to the support of stop collar 15b at it, thereby increased the intensity of stop screw 15a.
As shown in Figure 2, the fork-shaped section 10 of steering swivel 1 can comprise that the first arm 11 and the second arm 12, the first arms 11 and the second arm 12 are fixed on the wheel hub installation axial region 16 of steering swivel 1 by connecting portion 13.Thereby, aforementioned steering swivel 1 is hinged on the axletree 2, specifically refer on above-mentioned the first arm 11 and the second arm 12, the pin shaft hole (not shown) is set respectively, simultaneously in the end of axletree 2 pin shaft hole is set, pass pin shaft hole and steering swivel 1 is hinged on the axletree 2 by making the stub (not shown).As can be seen from the figure the end of axletree 2 is between the first arm 11 and the second arm 12.
Be appreciated that the locating part 15 that comprises stop screw 15a and stop collar 15b can be installed on a plurality of positions of fork-shaped section 10, the utility model is not limited this.In the present embodiment, mainly be that locating part 15 is arranged on the connecting portion 13 of fork-shaped section 10.At this moment, described spacing tapped bore 14 is arranged on the connecting portion 13, and stop screw 15a is installed in the tapped bore 14 after passing stop collar 15b.As seen from the figure, locating part 15 is positioned at a side of the end of axletree 2, when steering swivel 1 with respect to axletree 2 when turning to predetermined hard-over perpendicular to the outside direction of paper, locating part 15 will contact with the restriction protrusion 21 on the axletree 2, thus the relative motion between restriction steering swivel 1 and the axletree 2.
Will also be appreciated that Fig. 2 has only shown the situation of axletree 2 one ends.In practice, the two ends of axletree 2 are equipped with steering swivel 1 symmetrically, and limiting section is arranged on the axletree 2 symmetrically simultaneously, and are provided with corresponding locating part 15 on each steering swivel 1.Like this, no matter vehicle is turnon left or right-hand corner, can by carry out the control of hard-over at the steering swivel position limiting structure, prevent that steering swivel from colliding suspension etc., and cause the interference between the parts.
Along with the development of vehicle, except having front-wheel steering, also develop the technology such as rear-axle steering in the vehicle.Therefore, in the utility model, described axletree 2 both can be front axle, also can be rear axle.In present embodiment, axletree 2 is front axle.
According to above description, the utility model can relate to a kind of steering swivel system, and this steering swivel system comprises above-described steering swivel position limiting structure.In addition, the utility model also relates to a kind of vehicle, and this vehicle comprises this steering swivel system.After adopting above-mentioned steering swivel position limiting structure, reduced the time of setting up of vehicle, improved the efficiency of assembling of vehicle.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.As long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
