Embodiment
Below to drive the adjusting nut keying structure that in vehicle bridge, main passive cone gear and differential mechanism use, the invention will be further described by reference to the accompanying drawings.Those skilled in the art will be understood that embodiment disclosed in this specification is only explanation the present invention, can not be construed as limiting the invention.
Adjusting nut keying structure of the present invention comprises adjusting nut and lock banking stop, and the end face ring of adjusting nut is provided with ditch for holding dead bolt or groove; Lock banking stop is hub-and-spoke configuration, and it is along the circumferential direction provided with some dead bolts.Lock banking stop be arranged on adjusting nut center for the center of circle circumferentially, and the line at lock banking stop mounting hole center and adjusting nut center has certain offset distance relative to dead bolt working surface.
Fig. 3 and Fig. 4 gives structure of the present invention for keying structure during different adjusting nuts.
As shown in Figure 3, in one embodiment of the invention, adjusting nut 1 end face ring is provided with outstanding end-tooth 8, just defines the inter-tooth slots holding dead bolt 7 between the tooth of every pair of end face.Lock banking stop 2 is all the arc structure be attached thereto in the both sides of every sheet dead bolt 7, and when dead bolt 7 to insert between end-tooth 8 in groove, the circular arc 6 on its both sides just fits on the outer peripheral surface of end-tooth 8, can improve locking effect further like this.
As shown in Figure 4, in another embodiment of the present invention, adjusting nut 1 is equipped with end face groove 9 radially in end face outer rim, and dead bolt 7 can directly be inserted in end face groove, and now the circular arc 6 on dead bolt 7 both sides just fits on the outer peripheral surface of adjusting nut 1.
With reference to figure 3 or Fig. 4, can find out, because adjusting nut 1 moves back along a direction pine all the time, such as counterclockwise, therefore the even whole locking plate of dead bolt only has a working surface (i.e. stress surface), certain offset distance is had, as shown in Figure 6 between this working surface and the line OO ' between adjusting nut center and locking plate mounting hole center.Because locking plate can use by tow sides, therefore, the situation that the hypothesis adjusting nut that we see in figure 6 moves back toward clockwise direction pine.Contrast with the situation of Fig. 3 or Fig. 4, we find, when to move back direction be counterclockwise for the pine of adjusting nut, the working surface of dead bolt is positioned at left side; When to move back direction be clockwise for the pine of adjusting nut, the working surface of dead bolt is located in right side.Assuming that nut only moves back along a direction pine all the time, and each lock banking stop can use by tow sides.Therefore, for having the lock banking stop of three dead bolts, it has six lock positions, six working surfaces.
As shown in Figure 6, in order to reach when adjusting nut is adjusted, pine moves back little amount or moves back without the need to pine just can lock adjusting nut with lock banking stop, require that each working surface of every sheet dead bolt is not identical with the offset distance of lock banking stop mounting hole line OO ' relative to adjusting nut center hole, i.e. a1 ≠ a2 ≠ a3.Further, because locking plate has six working surfaces (tow sides all can use), therefore require when shown in Fig. 3 or Fig. 4, still can meet above-mentioned requirements, just need to meet following condition simultaneously:
1)a1≠a2≠a3≠a/2；
2)a1+a2≠a；
3)a2+a3≠a；
4)a1+a3≠a。
Guarantee lock banking stop has six different lock positions.
Wherein, the width of dead bolt is relevant to the width of the ditch that adjusting nut end face provides or groove, and optimal cases is as shown in Figure 3 or Figure 4, and dead bolt 7 inserts in inter-tooth slots or end face groove 9 just.Offset distance a1, a2 and a3 relate to the mounting point of lock banking stop.Composition graphs 3 ~ 5, the mounting point figure of lock banking stop 2 is determined jointly by parameter alpha and R, and namely locking plate mounting hole is centrally located at adjusting nut center for the center of circle, with R be radius circumferentially, and to form an angle α with level, mounting hole particular location is determined by practical application.The concrete structure of lock banking stop and size can be determined according to the structure of adjusting nut and size.After determining the shape of adjusting nut, structure and size, just can determine the dead bolt width a of lock banking stop; Then according to aforesaid equation, method by experiment can calculate the parameter alpha and R that determine lock banking stop mounting point, offset distance a1 ~ a3 can rule of thumb select arbitrarily within the specific limits.
Composition graphs 3, Fig. 4 and Fig. 6 can find out, lock banking stop 2 is hub-and-spoke configuration, and lock banking stop is along the circumferential direction provided with some dead bolts 7, is preferably 2 ~ 4.Have three dead bolts in the present embodiment, the width of every sheet dead bolt is a, the circular arc 6 that it is the center of circle that the both sides of every sheet dead bolt are designed with the center of adjusting nut respectively.The shape and size of described circular arc depend on structure and the size of adjusting nut.
To drive the adjusting nut keying structure that in vehicle bridge, passive cone gear and differential mechanism use, during owing to adjusting gears meshing and bearing pre-fastening at every turn, end face teeth groove on adjusting nut all can not have identical position relative to the center of adjusting nut, therefore wish after the engagement of bearing pre-fastening, gear is adjusted, adjusting nut need not loosen or loosen very small angle, just just can coordinate installation with lock banking stop, optimal situation is the locking realizing adjusting nut under the prerequisite of not rotating adjusting nut.As seen from Figure 6, six working surfaces (six kinds of different offset distances: a1, a2, a3, a-a1, a-a2, a-a3) can be had selective when installing lock banking stop.The final foundation selected makes adjusting nut rotate minimum angle as far as possible after other component are adjusted.The arc structure of dead bolt both sides can more effectively prevent from adjusting nut from loosening exiting.
By embodiment, adjusting nut keying structure of the present invention and lock banking stop are described in detail above.Wherein, for the needs explained the present invention, to concrete shape and the structure of adjusting nut, and the embody rule of adjusting nut keying structure is illustrated, but it should not be construed as limitation of the present invention.
