Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 3-4, the utility model provides a kind of yoke configurations of leaf spring, this yoke configurations comprises U-shaped plate 35, bolt 32, nut 33 and cushion pad 34, and described U-shaped plate 35 comprises the first side plate 52, second side plate 53 and base plate 51, and base plate 51 is riveted in plate spring sheet 04.The end of the first side plate 52 and the second side plate 53 has through hole along on same axial direction, namely the center line of two through holes overlaps and is parallel to described base plate 51, bolt 32 coordinates with nut 33 from side through through hole, is subject to plate spring sheet 04 impacts rear outward-dipping to prevent the first side plate 52 and the second side plate 53.Position-limited lever 31 is also comprised in this structure, the both ends of the surface of position-limited lever 31 are fitted with the inner side of the first side plate 52, second side plate 53 respectively, namely the two ends of position-limited lever 31 are against the first side plate 52 side relative with on the second side plate 53 respectively, do not tilt to ensure the relative position of the first side plate 52 and the second side plate 53 to fix to the other side.Such plate spring sheet 04 and remain certain distance between the first side plate 52 and the second side plate 53, thus plate spring sheet 04 and the contact of cushion pad 34 can be reduced, reduce friction frequency.Obviously, compared to the content described in prior art, yoke configurations provided by the utility model is not easy to wear, thus can increase the service life.
In said structure, can adopt the form that one is processed between position-limited lever 31 and U-shaped plate 35, after also can adopting separate machined, recombinant is to mode together, specifically can choose flexibly according to actual conditions.In the utility model embodiment, in order to simplify single part structure, be convenient to production operation, preferably have employed the mode removably connected.
Further, fix for making the relative position between position-limited lever 31 and U-shaped plate 35, ensure structure stability, position relative inside the first side plate 52 with the second side plate 53 respectively can process the groove of definite shape, the two ends of position-limited lever 31 are against in groove respectively; Or respectively on the same axial direction of the first side plate 52 and the second side plate 53 increase a through hole, then position-limited lever 31 is processed into ladder-type, the cross-sectional dimension of intermediate portion is made to be greater than the cross-sectional dimension at two ends, the distance between the first side plate 52 and the second side plate 53 can be limited like this, position-limited lever 31 radially vibration can be prevented again.More preferably, in the utility model embodiment, position-limited lever 31 adopts tubular structure, and position-limited lever 31 can directly be enclosed within described bolt 32, and compared to above-mentioned two schemes, obviously the dismounting of this structure installment is more convenient, and technique is simpler.
In addition, in order to increase the wear resistance of cushion pad 34, extending the working life of yoke configurations further, the better elastic material of some wear resistancies can be selected to make cushion pad 34, as nylon alloy material.
Further, in the utility model embodiment, also adopt and removably connect between cushion pad 34 and U-shaped plate 35, such cushion pad 34 can be changed separately after wearing and tearing, and need not change a whole set of yoke configurations, thus can reduce maintenance cost.
Certainly, the above-mentioned mode that removably connects also has multiple, such as processes projection in the side of cushion pad 34, then punches on the first side plate 52 and the second side plate 53, the projection on cushion pad 34 is stuck in the hole of the first side plate 52 and the second side plate 53; Such as cushion pad 34 is made again the form of sleeve, cushion pad 34 is directly enclosed within the outer circumferential face of the first side plate 52 and the second side plate 53 from one end, and described outer circumferential face refers to the ring surface that the surface of the first side plate 52 and the second side plate 53 is formed.Comparatively speaking, rear a kind of Placement is installed, it is more convenient to dismantle, and fixing also more reliable, therefore the utility model embodiment preferably adopts rear a kind of Connecting format.
Further; consider that cushion pad 34 has certain elasticity; can better be fixed on the first side plate 52 or the second side plate 53 for making cushion pad 34; the inner cross-sectional dimension of usual cushion pad 34 is slightly less than the cross-sectional dimension of the first side plate 52 or the second side plate 53, but can increase installation difficulty again like this.For this reason, in the utility model embodiment, change the cross section of cushion pad 34 into rectangle frame structure, the part that rectangle frame structure is fitted with the outside of the first side plate 52, second side plate 53 is respectively provided with opening, after on the outer circumferential face that cushion pad 34 is stuck in the first side plate 52 or the second side plate 53, rectangle frame structure generation resiliently deformable, like this can be fixed under cushion pad 34 self-acting.In addition, this structure can directly utilize opening be stuck in by cushion pad on the first side plate 52 or the second side plate 53 or take off, and without the need to demounting bolt 32, nut 33, operation is simpler, convenient.The outside of above-mentioned first side plate 52, second side plate 53 refers to the side away from the other side on the first side plate 52, second side plate 53 respectively.
Adopt the leaf spring of above-mentioned yoke configurations, its assembling, unloading process should adapt with above-mentioned yoke configurations, and because above-mentioned yoke configurations has above-mentioned technique effect, the leaf spring comprising this yoke configurations also should have corresponding technique effect.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
