Abstract
The utility model relates to a passenger train is with taking turns pullover that limit lock nut and this lock nut of dismouting used, it is with increasing the draw -in groove on the present lock nut outer lane, at overhead increase of cover and the corresponding fixture block of draw -in groove, when lock nut is tightened to needs, in the fixture block card advances the draw -in groove, then rotates pullover spanner dismouting lock nut to make things convenient for lock nut's dismouting, simple structure, convenient to use, required space is little, the dismouting of especially adapted light -tonnage passenger train axle. The utility model discloses simple structure, convenient to use, design are novel, simple improvement, can the current wheel limit lock nut of effectual solution with the hub in between round the clearance little, lack the problem of pullover operating space to make things convenient for the workman to operate, guarantee that wheel limit locking structure is firm reliable.
Description
Technical field
The utility model relates to the component technical field of objective vehicle wheel side locking mechanism, is specifically related to the pullover of a kind of objective vehicle wheel limit locking nut and this locking nut of dismounting.
Background technique
Along with the raising of development in science and technology and people's living standard, the requirement of people to the performance of passenger vehicle is more and more higher, namely requires that passenger vehicle has safety and steady and travels, requires that again passenger vehicle possesses certain travelling comfort.In the wheel limit structure of the driving system of passenger vehicle, the locking of wheel limit plays vital effect, and the locking of wheel limit ensures that wheel axle is to without play, guarantees the important guarantee of bus driving Security and stationarity.As shown in Figure 1, existing locking nut of taking turns limit locking is all outer hexagonal structure, as shown in Figure 2 and Figure 3, for for dismantle existing locking nut pullover be also hexagonal structure in the cylindrical that coordinates with outer hexagonal structure, when this kind of structure is in little tonnage vehicle bridge, because little tonnage axle structure is compact, gap between wheel hub inner circle and locking nut is less, lack pullover operating space, dismounting nut is more difficult, even likely cause wheel limit locking nut to be twisted not tight, bring hidden danger to bus safety.
Summary of the invention
In sum, in order to overcome the deficiency of prior art problem, the utility model provides the pullover of a kind of objective vehicle wheel limit locking nut and this locking nut of dismounting, it increases draw-in groove by existing locking nut outer ring, the fixture block corresponding with draw-in groove is increased on pullover, when locking nut tightened by needs, fixture block sticks in draw-in groove, then ring wrench dismounting locking nut is rotated, thus facilitating the dismounting of locking nut, structure is simple, easy to use, requisite space is little, is applicable to very much the dismounting of little tonnage passenger vehicle vehicle bridge.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of objective vehicle wheel limit locking nut, comprise nut body and internal thread, described nut body is outer hexagonal structure, is provided with internal thread in nut body, wherein: described nut body outer ring is provided with draw-in groove.
Further, described nut body outer ring is evenly distributed with three draw-in grooves.
A kind of dismounting above-mentioned objective vehicle wheel limit locking nut pullover, comprise pullover body and handle attachment hole, described pullover body is hexagonal structure in cylindrical, and one end of pullover body is provided with handle attachment hole, wherein: described pullover body is provided with fixture block.
Further, described fixture block is uniformly distributed on pullover body.
Further, in the end face that described fixture block is arranged on pullover body or pullover inner body wall.
The beneficial effects of the utility model are:
1, the utility model increases draw-in groove by existing locking nut outer ring, the fixture block corresponding with draw-in groove is increased on pullover, when locking nut tightened by needs, fixture block sticks in draw-in groove, then rotates ring wrench dismounting locking nut, thus facilitates the dismounting of locking nut, structure is simple, easy to use, requisite space is little, is applicable to very much the dismounting of little tonnage passenger vehicle vehicle bridge.
2, the utility model structure is simple, easy to use, novel, simple improvement, effectively can solve that existing to take turns gap between limit locking nut and wheel hub inner circle little, lacks the problem of pullover operating space, thus facilitate operative, ensure that wheel limit locking mechanism is solid and reliable.
accompanying drawing illustrates:
Fig. 1 is the structural representation of existing locking nut;
Fig. 2 is the pullover structural representation of the locking nut shown in dismounting Fig. 1;
Fig. 3 is that schematic diagram is looked on a left side of Fig. 2;
Fig. 4 is the structural representation of locking nut of the present utility model;
Fig. 5 is the pullover structural representation of the locking nut shown in dismounting Fig. 4;
Fig. 6 is the left TV structure schematic diagram of the utility model Fig. 5.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 4, Fig. 5, Fig. 6, a kind of objective vehicle wheel limit locking nut, nut body 1 and internal thread 2, described nut body 1 is outer hexagonal structure, is provided with internal thread 2 in nut body 1, and described nut body 1 outer ring is evenly distributed with three draw-in grooves 3.
A kind of dismounting above-mentioned objective vehicle wheel limit locking nut pullover, comprise pullover body 4 and handle attachment hole 5, described pullover body 4 is hexagonal structure in cylindrical, and one end of pullover body 4 is provided with handle attachment hole 5, described pullover body 4 is evenly distributed with three fixture blocks 6.Fixture block 6 is arranged on the end face of pullover body 4.
During use, pullover handle attachment hole 5 is connected with handle, and then pullover three fixture blocks 6 is connected with three draw-in grooves 3 of locking nut respectively, then rotatory handling, i.e. dismantled and assembled locking nut.
Pullover fixture block 6 of the present utility model can also be arranged on the inwall of pullover body 4.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
