The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Have the multiple spare tyre lifter that spare tyre goes up and down that is used in the prior art, the spare tyre cranking-bar assembly of the utility model is applicable to the spare tyre lifter of sprocket-type.
Referring to Fig. 1; The spare tyre cranking-bar assembly of the utility model comprises the more piece rocking bar that removably links together successively; The end of first joint rocking bar is equipped with the pin rod 11 that cooperates with spare tyre lifter input shaft in the more piece rocking bar; The minor details rocking bar cooperates with jiggle bar 4, this jiggle bar 4 axially and minor details rocking bar axial vertical.Can find out that from said structure first joint rocking bar is used with the spare tyre lifter, can realize the up-down of spare tyre lifter, make things convenient for the taking-up of spare tyre and take in that wherein, the axial direction of pin rod 11 need save the axial vertical of rocking bar with head.The minor details rocking bar cooperates with jiggle bar 4; When up-down spare tyre lifter,, can make operating personal relatively easily rotate whole spare tyre cranking-bar assembly because the axial and minor details rocking bar of jiggle bar 4 is axial vertical; Thereby transmit torque on the sprocket wheel of spare tyre lifter, drive sprocket rotation.
Compare with the spare tyre rocking bar that length in the prior art is long,, thereby can the more piece rocking bar be taken apart, be convenient to deposit owing to the utility model spare tyre cranking-bar assembly is removably linked together by the more piece rocking bar.Fit together through simple mode in use, thereby have long length, be convenient to operation.Wherein the number of more piece rocking bar should correspondingly increase or reduce according to the needs of reality.The utility model does not limit this.
Below to the spare tyre cranking-bar assembly comprise three the joint rocking bars situation describe.
As shown in the figure; The more piece rocking bar comprises first segment rocking bar 1, the second joint rocking bar 2 and the 3rd joint rocking bar 3; First segment rocking bar 1 is as first joint rocking bar, thereby at the end of first segment rocking bar 1 installation pin rod 11, the axial direction of pin rod 11 is perpendicular to the axial direction of first segment rocking bar 1.The 3rd joint rocking bar 3 is as the minor details rocking bar, thereby the 3rd joint rocking bar 3 is used for cooperating with jiggle bar 4.
Above-mentioned three joint rocking bars can be accomplished in several ways removably and connect; For example; Can three joint rocking bars all be set to hollow stem, in the end of adjacent two joint rocking bars the identical tapped bore of diameter be set respectively, then a joint rocking bar deeply saved in rocking bar to another; At last fastener 6 (bolt etc.) is fixed on above-mentioned tapped bore simultaneously, thereby realizes the connection of two joint rocking bars.After finishing using, fastener 6 is back-outed, just can rocking bar be deposited.
Carry out in the moment transmission process at the spare tyre cranking-bar assembly, can find out from attachment point and stressing conditions, the moment of torsion that the second joint rocking bar 2 in the above-mentioned three joint rocking bars bears is maximum.Therefore, preferably the diameter of first segment rocking bar 1 and the 3rd joint rocking bar 3 is set to the diameter less than the second joint rocking bar 2, thereby increases the intensity of whole spare tyre cranking-bar assembly.
The 3rd joint rocking bar 3 cooperates with jiggle bar 4 as stated, is convenient to operation.Fit system wherein can have multiple, for example can be to be similar to the mode of above-mentioned more piece rocking bar through fastener to be combined together, with carry-over moment.
Preferably; The cross section of the 3rd joint rocking bar 3 ends is set to polygon; And, on the end that hole 41 is sleeved on the 3rd joint rocking bar 3, realize that jiggle bar 4 and the 3rd saves being connected of rocking bar 3 in the setting in the radial direction of jiggle bar 4 and the corresponding hole 41 of end cross-sectional of the 3rd joint rocking bar 3.
More preferably, the cross section of the 3rd joint rocking bar 3 ends is set to quadrangle, and hole 41 also is set to quadrilateral hole simultaneously, and matching with hole 41 in the end of the 3rd joint rocking bar 3, saves rocking bar 3 and jiggle bar 4 to connect the 3rd, and transmit rotational force.Tetragonal structure can guarantee the transmission of moment well with respect to triangular structure, and than the processing of being more convenient for of other polygonized structures.
In addition, can also give full play to the effect of jiggle bar 4.One end of jiggle bar 4 is set to wedge structure, plays the effect of tire lever; The other end of jiggle bar 4 vertical extent from the jiggle bar 4, and on the axial direction of end, hexagon ring is set can be realized the function of wheel nut spanner, before the replacement spare tyre, is used for removing and installing bolt on original tire etc.
The spare tyre cranking-bar assembly of more than describing is mainly used in the up-down of spare tyre.The spare tyre cranking-bar assembly of the utility model can also be used for the off-load operation of jack in addition.Identical with aforesaid embodiment; The spare tyre cranking-bar assembly of the utility model comprises the more piece rocking bar that removably links together successively; The end of first joint rocking bar is equipped with the pin rod 11 that cooperates with spare tyre lifter input shaft in the more piece rocking bar; Different is that the minor details rocking bar cooperates with an end of jack handle 5, and this jack handle 5 has identical axis with the minor details rocking bar.
In theory, single off-load operation that just can realize hydraulic jack with regard to jack handle 5.But, in practical operation, need jack be arranged on the vehicle frame below, if operating personal is operated under vehicle frame, be extremely dangerous.Therefore, increase the more piece rocking bar in the utility model, to increase the entire length of rocking bar, so that carry out safe in operation.
Equally, the number of more piece rocking bar can be selected according to the real work situation.As shown in the figure, the more piece rocking bar can comprise first segment rocking bar 1, the second joint rocking bar 2 and the 3rd joint rocking bar 3, and first segment rocking bar 1 is as first joint rocking bar, and the 3rd joint rocking bar 3 cooperates with jack handle 5 as the minor details rocking bar.Same consideration stressing conditions, preferably the diameter of first segment rocking bar 1 and the 3rd joint rocking bar 3 is set to the diameter less than the second joint rocking bar 2, improves bulk strength.
In addition, the end of the other end of jack handle 5 is provided with and is used for the groove 51 that cooperates with jack.Cooperating of unloader valve about jack handle 5 and jack is common technology means known in those skilled in the art, repeats no more here.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But the utility model is not limited to the detail in the above-mentioned embodiment, in the technical conceive scope of the utility model; Can carry out multiple simple variant to the technical scheme of the utility model; For example, can change the mode of removably connecting of more piece rocking bar into clamping etc., these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
