Now, as shown in Figure 7 and Figure 8, the inside and outside both sides end face of eccentric wheel 5 forms two friction pairs 2 with the outside face of the shaft shoulder 31 and the inside face of axle center hole 41 respectively, assuming that two parts forming described friction pair 2 are respectively the first friction member 21 and the second friction member 22, second friction member 22 can rotate around the first friction member 21 circumference, and when the angle needing seat angle adjustor to seat regulates, in friction pair 2 in seat angle adjustor, the second friction member 22 can produce radial upset by relative first friction member 21; Wherein, eccentric wheel 5 forms described second friction member 22, and the inwall of the shaft shoulder 31 or axle center hole 41 forms described first friction member 21.
In like manner, the inside and outside both sides end face of wedge 6 also forms two friction pairs 2 with the outside face of the shaft shoulder 31 and the inside face of axle center hole 41 respectively; Wherein, wedge 6 forms described second friction member 22, and the inwall of the shaft shoulder 31 or axle center hole 41 forms described first friction member 21.
Seat angle adjustor of the present invention is also provided with tapering element 1, and tapering element 1 is arranged in certain friction pair 2, is between the first friction member 21 and the second friction member 22; The end face that tapering element 1 is in both sides is respectively the first end face 11 and the second end face 12, first end face 11 is arranged to the face of cylinder, this face of cylinder is arranged towards the first friction member 21, and identical or close with the shape of the friction face of the first friction member 21, so that this first end face 11 matches with the friction face of the first friction member 21; Second end face 12 is set to curved surface, and arrange towards the friction face of the second friction member 22, when the relative first friction member 21 radial direction upset of the second friction member 22, the friction face of the second friction member 22 can be resisted against on the second end face 12, thus contacts or linear contact lay with the second end face 12 forming surface.
It should be noted that, the nouns of locality such as inner side herein, outside are all with the axial line of seat angle adjustor for benchmark defines, and that is, the side away from described axial line is described outside, are described inner side near the side of described axial line; The direction vertical with described axial line is described radial direction; Described both sides refer near the side of described axial line and the side away from described axial line.
For ease of understanding, being only arranged on the friction pair 2 that formed by eccentric wheel 5 and the shaft shoulder 31 for tapering element 1 herein and being described, please refer to Fig. 7-11.But this can not be interpreted as that tapering element 1 of the present invention only can be arranged between eccentric wheel 5 and the shaft shoulder 31; When tapering element 1 is arranged on other friction pairs 2, can arrange with reference to its structure between eccentric wheel 5 and the shaft shoulder 31.
Tapering element 1 with one side end face towards the shaft shoulder 31, this side end face is the first end face 11, first end face 11 and is set to identical or close with the excircle of the shaft shoulder 31 cylindric, then the first end face 11 is fitted in the outer wall of the shaft shoulder 31, both forming surface contacts, as shown in figures s-11; Tapering element 1 is with its opposite side end face towards eccentric wheel 5, and this opposite side end face forms the second end face 12, second end face 12 and is set to curved surface, substantially fits, as shown in Figure 9 and Figure 10 with the inwall of eccentric wheel 5.
Please further refer to the close-up schematic view figure that Figure 12, Figure 12 are along eccentric wheel after the cutting of C-C direction and shoulder in Fig. 8.
Under normal circumstances, substantially there is not gap diametrically between eccentric wheel 5 and the shaft shoulder 31, eccentric wheel 5, with the outer wall of its inner wall surrounding at the shaft shoulder 31, can realize face contact substantially; When seat adjusts the angle of machine to seat to adjust, eccentric wheel 5 is relative to the radially outward upset of the shaft shoulder 31, and now, the inwall of eccentric wheel 5 outwards overturns successively around the curved surface of the second end face 12, then with the second end face 12, eccentric wheel 5 remains that face contacts or linear contact lay, as shown in figure 12; Relative to the point cantact of eccentric wheel in the prior art shown in Fig. 65 with the shaft shoulder 31, be provided with the eccentric wheel 5 of tapering element 1 and between the shaft shoulder 31, remain that face contacts or linear contact lay, thus reduce the rate of wear largely, improve the durability of eccentric wheel 5 and the shaft shoulder 31.
Can expect, eccentric wheel 5 can arrange groove 51, groove 51 is for holding tapering element 1, then tapering element 1 can circumference be fixedly attached in groove 51, when eccentric wheel 5 rotates around the shaft shoulder 31 circumference, tapering element 1 can be driven to rotate around the shaft shoulder 31 circumference, then tapering element 1 constantly can adjust the relative position relation with the shaft shoulder 31, so that with the outer wall of the shaft shoulder 31, the first end face 11 can remain that face contacts or linear contact lay.
It will also be appreciated that, tapering element 1 can also be arranged between the inwall of eccentric wheel 5 and axle center hole 41, now can arrange groove 51 at the outer face of eccentric wheel 5, to hold tapering element 1; Tapering element 1 is that the first end face 11, first end face 11 is set to the face of cylinder identical or close with the inwall of axle center hole 41, to be mated towards the end face of the inwall of axle center hole 41; Tapering element 1 is the second end face 12 towards a side end face of the outer wall of eccentric wheel 5, and this second end face 12 is also set to curved surface; When the radially outward upset of eccentric wheel 5 relative to axle center hole 41, the outer wall of eccentric wheel 5 overturns successively around the curved surface of the second end face 12, remains face contact or linear contact lay.
In like manner, between wedge 6 and the shaft shoulder 31, between wedge 6 and the inwall of axle center hole 41, also tapering element 1 can be set, the embodiment that specifically can be arranged between eccentric wheel 5 and the shaft shoulder 31, between eccentric wheel 5 and the inwall of axle center hole 41 with reference to tapering element 1 carries out corresponding configuration, repeats no more herein.
Certainly, wedge 6 also can arrange installation groove in its side end face towards the shaft shoulder 31, installs in groove so that tapering element 1 circumference is fixedly mounted in; In addition, wedge 6 can also arrange installation groove towards a side end face of axle center hole 41, to hold and to install tapering element 1.
Theoretically, above-mentioned four friction pairs 2 all can arrange tapering element 1, but, consider the complexity of structure, on the friction pair 2 that usually only need be formed at eccentric wheel 5 and the shaft shoulder 31 or on the friction pair 2 that formed of the inwall of eccentric wheel 5 and axle center hole 41, a tapering element is set, that is, when eccentric wheel 5 is as the second friction member 22, tapering element 1 can be set in the inner friction surface of eccentric wheel 5 or outer friction surface, to carry out conicity regulation during eccentric wheel 5 axial turning, without the need to all arranging tapering element 1 on two friction pairs 2; In like manner, when wedge 6 is as the second friction member 22, in the friction pair 2 that the friction pair 2 that can be formed at wedge 6 and the shaft shoulder 31 or the inwall of eccentric wheel 5 and axle center hole 41 are formed, optional one arranges tapering element 1, to meet conicity regulation during wedge 6 axial turning.
Correspondingly, when service life is enough, the friction pair 2 that can only be formed at eccentric wheel 5 or wedge 6 arranges a tapering element 1, such as also can not arrange tapering element between wedge 6 and the shaft shoulder 31, between wedge 6 and the inwall of axle center hole 41, the rotation by means of only wedge 6 adapts to the tapering change in chair angle adjustment process.
Obviously, when all arranging tapering element 1 in above-mentioned four friction pairs 2, whole seat angle adjustor is more stable in the process of angular adjustment, and the friction face of friction pair 2 can remain face contact or linear contact lay, thus extend seat service life, improve traveling comfort.
Please refer to Figure 13 and Figure 14, Figure 13 is the first side isometric view of a kind of set-up mode of tapering element provided by the present invention; Figure 14 is the second side isometric view of a kind of set-up mode of tapering element provided by the present invention.
Tapering element 1 of the present invention has the first end face 11 and the second end face 12, first end face 11 can adopt abrasion-resistant material to make, so that the friction of the inwall of opposing and the shaft shoulder 31 or axle center hole 41; Second end face 12 is curved surface, and described curved surface can be the structure such as sphere or cylinder profile, to adapt to the connection requirement of eccentric wheel 5 or wedge 6 better, as shown in figure 14.
Obviously, tapering element 1 of the present invention can overallly adopt the good material of mechanical property to make, and may improve intensity to enter, and extends its service life, reduces the rate of wear.
Adopt tapering element of the present invention, the friction pair in seat angle adjustor can be made to be in face contact or linear contact lay all the time, to reduce parts depreciation speed, extend the service life of seat angle adjustor and seat; On the other hand, because the contact between friction face remains face contact or linear contact lay, then seat angle adjustor can be supported by face or line in the process regulated, and then improve the reliability connected, thus effectively prevent rocking of seat, avoid producing noise in control process, improve the traveling comfort of seat.
In addition, four friction pairs 2 mentioned above are only four friction pairs 2 more common in seat angle adjustor, when there are other friction pairs 2 in seat angle adjustor, also tapering element 1 can be set on other friction pairs 2, then analogy said structure is arranged, to reach the effect of conicity regulation, reduce the wearing and tearing of parts.
Please refer to Figure 15, Figure 15 is the cross-sectional view that tapering element provided by the present invention is arranged on other friction pairs.
As shown in figure 15, between internal gear 3 and outer tooth plate 4, be filled with two or more friction member 7, and when the area discrepancy of each friction member 7 is less, each friction member 7 can all arrange tapering element 1, to realize the adjustment of tapering better, reduce the rate of wear and severe degree.
