Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 2-Fig. 4, in a kind of detailed description of the invention, steering swivel provided by the present invention and vibration damper assembly, comprise steering swivel 201, damping 203 device, and successively through the bolt 202 of steering swivel 201 with bumper 203; Also comprise and be bolted in the black nut 204 that bolt 202 passes bumper 203 one end, black nut 204 comprises and is affixed on the locking section 205 of bumper 203 away from steering swivel 201 side, with the thread segment 206 being connected to locking section 205, locking section 205 is provided with taper hole 208, the opening of taper hole 208 increases near the direction of bumper 203, and the conical surface of taper hole 208 is crossing with the outer wall of locking section 205; Thread segment 206 is provided with the tapped bore 207 suitable with bolt 202, and tapped bore 207 is placed in the little end opening of taper hole 208 in the projection of the little transverse plane of taper hole 208.
Above-described embodiment arranges taper hole 208 by the locking section 205 of black nut 204, and the conical surface of taper hole 208 is crossing with the outer wall of locking section 205, black nut 204 is under the effect of screw-down torque, conical surface generation elastic deformation, the conical surface and bumper 203 are fitted, increases its area of contact, after tightening, prevent loosening of in vehicle movement process black nut 204 by the elastic force of the conical surface and the effect of thrust, improve the safety that vehicle travels.
Thread segment 206 and the machine-shaping of locking section 205 one.
Tapped bore 207 and taper hole 208 are coaxially arranged, and this structure adds and uses same benchmark man-hour, is convenient to processing.Tapped bore 207 and taper hole 208 can disalignment be arranged, and tapped bore 207 is placed in the little end opening of taper hole 208 in the projection of the little transverse plane of taper hole 208, and namely tapped bore 207 runs through taper hole 208 completely.Tapped bore 207, taper hole 208, locking section 205 and thread segment 206 can coaxially be arranged, and are convenient to processing.
Locking section 205 is cylinder, and taper hole 208 is the conical bore coaxial with cylinder.This structure is convenient to processing.Locking section 205 also can be prism, and taper hole 208 is the pyramid hole adapted with locking section, and such as locking section 205 is six prisms, and taper hole 208 is hexagonal pyramid hole, and each conical surface in hexagonal pyramid hole intersects to the corresponding faceted pebble of six prisms.
The end diameter of preferred taper hole 208 equals the large footpath of tapped bore 207, and make taper hole under the structure of the same height of locking section 205, taper angle is maximum, thus improves the elasticity of locking section 205, increases the coupling mechanism force of black nut 204.The end diameter of taper hole 208 also can be greater than the large footpath of tapped bore 207.
Be provided with unthreaded hole 209 between tapped bore 207 and taper hole 208, the diameter of unthreaded hole 209 is greater than the large footpath of tapped bore 207.This structure can prevent the damage causing tapped bore 207 when processing taper hole 208, affects the installation of black nut 204.
Be provided with chamfering between taper hole 208 and unthreaded hole 209, avoid the wedge angle between taper hole 208 and unthreaded hole 209, can not scratch bolt 202. when black nut 204 is installed
Locking section 205 is provided with buckle; Bumper 203 is provided with near the one side of black nut 204 claw being connected in buckle.This structure increases the coupling mechanism force of black nut 204, thus improve the safety of vehicle.
Preferred buckle is ratchet, and claw is ratchet, and when black nut 204 is locked, described ratchet snaps in the teeth groove of ratchet.This structure makes clamping more firm.Claw is installed on bumper 203 by screw, and when black nut 204 rotates to locking direction, ratchet is inoperative; When after locking, ratchet snaps in teeth groove, limits black nut 204 and rotates towards unlocking direction; When dismounting is keeped in repair, screw can be unclamped claw is taken off, to unlock black nut 204.
Buckle also can for the prism in locking section 205, and claw is the elastic bumps on bumper 203, the circumscribing circle being centrally located at prism of elastic bumps, and after black nut 204 is locked, elastic bumps elastic deformation compresses prism.
The external diameter of thread segment 206 is less than the external diameter of locking section 205.This structure, when spanner clamping thread segment 206, is tightened black nut 204 for spanner and is provided support, handled easily.
The thickness of locking section 205 is 1/1 to two/3rd of black nut 204 thickness.This structure can ensure to lock the intensity of section 205, prevents due to locking that section 205 is too thin ftractures under the effect of screw-down torque, and locking section 205 was lost efficacy.The thickness of locking section 205 can be 1/3rd, 1/2nd of black nut 204 thickness, or 5/12nds.
The outer wall of thread segment is six prisms or quadrangular.Convenient wrench operates.
Bumper 204 is provided with boss near the side of black nut 204, and described bolt 202 is through the through hole of boss, and black nut 204 is affixed on boss.Boss attachment face is set separately, large area can be avoided to be difficult to process smooth problem, thus make installation more stable.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
