Abstract
A novel combined tire nut comprises a nut and a washer, is characterized in that the nut and the washer are sheathed and riveted with each other and can rotate relative to each other; a flange at the lower end of the nut can be movably buckled with an inner ring surface at the upper part of the washer; the upper end surface of the washer and the step surface of the nut are in sphere coordination with each other; a loop is extended from the lower part of the washer; the nut is provided with a groove; the upper end of the groove is a step surface which forms a convex annular sphere; the upper end surface of the washer is a concave annular sphere matched with the step surface. With the novel combined tire nut, the shear stress born by the tire nut is reduced, and the stress center of the nut can be adjusted automatically, so that tension born by the nut coincides with the axis, the added bending moment of the nut is reduced, the service life of the nut is prolonged, and the safety of a vehicle is improved.
Description
Technical field
The utility model relates to automotive field, especially a kind of for motor vehicle lug nut.
Background technique
At present, the tire bolt assembly is when fastening automotive wheel, dismounting for the ease of automotive wheel, the tire screw diameter of tire bolt assembly is generally than the little 4-6mm of boss bolt bore dia, because the factor of diameter difference causes wheel to form irregular running when walking, automobile produces great shearing force to the automobile tire bolt when jolt vibration and brake are impacted like this, cause the tire bolt assembly impaired, shortened the working life of tire bolt assembly.In addition, the pad that is used with nut and the surface of contact of wheel are that supporting surface is the plane, if but this supporting surface deflection, the suffered support force of nut does not just overlap with the bolt axis, and bolt is subjected to the additional bending moment effect, greatly reduces the intensity of bolt, cause phenomenon of rupture to take place, above-mentioned situation all makes the working life of bolt shorter, and also fracture suddenly easily causes security incident.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel combination type lug nut, it can reduce the gap between wheel and the bolt, reduce the suffered shearing stress of bolt, energy is centering bolt center of effort automatically, and pulling force and dead in line that bolt is subjected to reduce the bolt additional bending moment, prolong bolt working life, strengthen the Security of vehicle.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of novel combination type lug nut, comprise nuts and washers, described nuts and washers socket riveted, can rotate relatively between packing ring and the nut, the lower end flange of nut and the top inner ring surface of packing ring interlock movably, sphere cooperates between the upper-end surface of packing ring and the step surface of nut, and the bottom of described packing ring is extended with the annular cover.
Further, described nut is provided with groove, and the upper end of groove is a step surface, and step surface is the annular sphere of evagination, and the upper-end surface of described packing ring is a concave spherical surface in the annular that matches with step surface.
Further, the lower end of described groove is the flange that turns over the taper of riveting formation, and the taper inner ring surface that riveted forms on this flange and the packing ring interlocks movably.Flange carries out axial limiting, and washer sets is contained on the nut.
Further, described packing ring comprises riveting part, dish portion and ring set, and the length of described ring set is not shorter than the length overall of riveting part and dish portion.
Has the sphere fitting surface between packing ring of the present utility model and the nut, make and to carry out the self adaption adjustment by sphere between nut and the packing ring, carry out self contering, automatic adjustment by packing ring, make support force that nut is subjected to all the time with the bolt dead in line, thereby improved the problem that bolt is subjected to additional bending stress, improved bolt strength; And the ring set that extends on the packing ring stretches between bolt and the wheel mounting hole, reduced the fit up gap between wheel mounting hole and the tire bolt, make wheel when walking, can not form irregular running, automobile is less to the shearing force that the automobile tire bolt produces when jolt vibration and brake are impacted like this, avoided the damaged phenomenon of tire bolt, thereby prolonged the working life of tire bolt, avoided tire bolt to rupture suddenly, strengthened the Security of vehicle.
The beneficial effects of the utility model are: reduced the suffered shearing stress of tire bolt, and automatic centering bolt center of effort, pulling force and dead in line that bolt is subjected to reduce the bolt additional bending moment, prolong bolt working life, strengthen the Security of vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.Below only be preferred embodiment of the present utility model, conduct is not to restriction of the present utility model.
As shown in Figure 1, a kind of novel combination type lug nut, comprise nut 1 and packing ring 2, described nut 1 and packing ring 2 socket riveteds, can rotate relatively between packing ring 2 and the nut 1, the flange 11 of nut 1 lower end interlocks movably with the top inner ring surface of packing ring 2, and sphere cooperates between the step surface 12 of the upper-end surface of packing ring 2 and nut 1, and the bottom of described packing ring 2 is extended with ring set 23.Described nut 1 is provided with groove, and the upper end of groove is a step surface 12, and step surface 12 is the annular sphere of evagination, and the upper-end surface of described packing ring 2 is concave spherical surfaces in the annular that matches with step surface 12.
As shown in Figure 1, the lower end of described groove is the flange 11 that turns over the taper of riveting formation, has the gap between the taper inner ring surface 24 that riveted forms on the flange 11 of this taper and the packing ring 2, interlocks movably.Described packing ring 2 comprises riveting part 21, dish portion 22 and ring set 23, and the length of described ring set is longer than the length overall of riveting part 21 and dish portion 22, makes that the length of thread engagement of ring set and bolt is enough, plays the effect that reduces shearing stress effectively.
Claims (4)
