Abstract
The utility model discloses an anti-rotation vehicle trailing arm. The anti-rotation vehicle trailing arm comprises flat iron, a vehicle trailing ball, a gasket, a nut and a square tube, wherein the lower portion of the vehicle trailing ball penetrates through the gasket and a through hole in one end of the flat iron in sequence to be connected with the nut. The anti-rotation vehicle trailing arm is characterized in that the gasket is provided with at least one upward protruding part and at least one downward protruding part, the downward protruding parts are embedded into a groove in the flat iron so that the relative rotation between the gasket and the flat iron can be limited, and the upward protruding parts are matched with the two side faces of the vehicle trailing ball so that the rotation of the vehicle trailing ball can be limited. The anti-rotation vehicle trailing arm has the advantages that the rotation between the vehicle trailing ball and the flat iron is limited by limiting the rotation between the gasket and the flat iron and the rotation between the gasket and the vehicle trailing ball, and the service life of the vehicle trialing ball and the service life of the flat iron are prolonged.
Description
Technical field
The utility model relates to a kind of anti-rotation tow arm, is specifically related to a kind of tow arm that can prevent tow ball rotation.
Background technology
Tow arm connects and is pulled car for tractor truck.Because different vehicle ball covers varies in size, therefore to be often designed to tow ball be detouchable to tow arm, is convenient to change the tow ball of different size when use.Meanwhile bring problem time, detouchable tow ball has rotation phenomenon in use, in the time frequently rotating between tow ball and band iron, can cause matching property between the two to decline, thread failure, bolt and nut assembling are loosening, produce potential safety hazard, shorten service life.
Utility model content
In view of this, the anti-rotation tow arm of one that the utility model provides, to solve the above-mentioned deficiency of prior art.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-rotation tow arm, comprise band iron, tow ball, packing ring, nut and square tube, the bottom of tow ball is spirally connected through through hole and the nut of packing ring and band iron one end successively, it is characterized in that, on packing ring, there is at least one upraised portion and at least one downward lug boss, downwards lug boss embeds groove on band iron with relatively rotating between restriction packing ring and band iron, and the rotation of tow ball is matched to limit in upraised portion and two sides on tow ball.Prevent the rotation between band iron and packing ring by downward lug boss, prevent the rotation between packing ring and tow ball by upraised portion, thus the rotation between restriction tow ball and band iron.
Further, between nut and band iron, be pressed with spring shim.Prevent the loosening of nut.
Preferably, upraised portion is dull and stereotyped, and flat board is close to the plane on tow ball.Prevent the rotation between tow ball and packing ring by two planes of being close to.
Preferably, on band iron, through hole position upper and lower surface all has the groove coordinating with downward lug boss.The tow sides of band iron all can trailer-erector ball, can tackle the poor tractor truck of differing heights and be pulled car when use.
Preferably, upraised portion has two and for tabular, and upraised portion is about the center of circle Central Symmetry of packing ring, and lug boss is not limited to one downwards.Upraised portion is with the identical manufacture of lug boss downwards and use all more convenient.
The beneficial effects of the utility model are: by the rotation between restriction packing ring and band iron, and rotation between packing ring and tow ball, thereby the rotation between restriction tow ball and band iron.The final service life that extends both.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described, obviously, accompanying drawing is described is only a part of the present utility model instead of whole embodiment.
As Figure 1-4, the anti-rotation tow arm of one that the utility model provides, comprise band iron 1, tow ball 2, packing ring 3, nut 4 and square tube 6, the bottom of tow ball 2 is spirally connected with nut 4 through the through hole 11 of packing ring 3 and band iron 1 one end successively, on packing ring 3, there is at least one upraised portion 31 and at least one downward lug boss 32, downwards lug boss 32 embeds groove 12 on band iron 1 with relatively rotating between restriction packing ring 3 and band iron 1, and upraised portion 31 and a plane 21 on tow ball 2 match to limit the rotation of tow ball 2.In application, while preventing that tow ball 2 from rotating, two lug bosses are main stress points, therefore must ensure that it can bear larger shearing force.Lug boss or the larger transverse plane 21 of selection, or select multiple lug boss producing balanced forces.
The anti-rotation tow arm that the utility model provides, the downward lug boss 32 of packing ring 3 embeds in band iron 1, therefore packing ring 3 can not and band iron 1 between rotate.And in order to make upraised portion 31 limit the rotation of tow ball 2, must ensure that the part that tow ball 2 contacts with packing ring 3 is not swivel, the cylindrical of its contact portion is not a complete circle.In the accompanying drawings, we have selected a plane 21, by a plane 21 and the upraised portion 31 of being close to plane 21, thus the rotation of prevention tow ball 2.As optionally, must not be a plane 21 here, groove 12, wavy surface can, a groove 12 coordinates a flat post, can stop equally tow ball 2 to rotate.In theory, an elliptic arc coordinate the rotation that can stop equally tow ball 2 with oval groove.
The anti-rotation tow arm that the utility model provides, as further improvement, selects 31, one downward lug bosses 32 of two upraised portion, and upraised portion is about Central Symmetry.And be flat post, like this, when manufacture, a kind of cooked mode of lug boss, all coordinates with flat post by a groove 12 on band iron 1 and tow ball 2.
It should be noted that, accompanying drawing middle washer 3 sizes, it is consistent with the size of tow ball 2 contacts site, therefore the rotation restriction site on tow ball 2 is plane 21 or groove 12, if but this contact site of tow ball 2 is greater than the size of packing ring 3, and this restriction site may be exactly a hole.This situation is equally applicable to band iron 1 and packing ring 3.
The description of technique scheme has only embodied optimal technical scheme of the present utility model, and is not exhaustively, or the utility model is limited to disclosed form.Based on embodiment of the present utility model, the other forms of technical scheme that anyone obtains under the prerequisite of not making creative work, though its in structure or make in form which kind of change, within all belonging to protection domain of the present utility model.
