Abstract
A load balancing type tire bolt component comprises a bolt, a nut and washers, and is characterized in that the washers consist of a first washer and a second washer, the first washer and the second washer are in spherical fit and are assembled on the nut, the two washers are located at the end of the nut, and the outer side end surface of the second washer is located outside the end surface of the same side of the nut. The load balancing type tire bolt component reduces additional bending load on the bolt, increases the strength of the bolt, balances load distributed on the axis of the bolt, and accordingly prolongs the service life of the bolt. The fastening property of the bolt is good, and the safety of a vehicle is strengthened.
Description
Technical field
The utility model relates to automotive field, especially a kind of used for vehicle tyre bolt assembly.
Background technique
Tire bolt plays crucial effects as firm of fastening automotive wheel.Phenomenon of rupture often takes place in the tire bolt that is applied in medium and heavy dumping car at present, cause more serious accident, fracture mode is mainly crooked fatigue fracture, illustrates that bolt has been subjected to additional bending stress, flexural stress has reduced the intensity of bolt, makes the bolt crooked fatigue fracture.Common tire bolt assembly is made up of bolt, nut and pad, pad have with nut be one, independent pad is also arranged, but because the surface of contact of pad and wheel is 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 reduce the intensity of bolt, cause phenomenon of rupture to take place.When conventional lug nut cooperates with tire bolt, the bolt tension, the nut pressurized, the pitch variation tendency is inconsistent, and the 1st circle that causes 1/3 thrust load to concentrate on cooperatively interacting is gone up on the screw thread, the later screw thread of 8 circles bears thrust load hardly, be that load distribution on the screw thread is inhomogeneous, majority concentrates on the first lap screw thread, causes local yielding fatigue, produce bolt fracture or loosening, extremely dangerous.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of tire bolt assembly of energy balancing load, it can reduce the addition bend load on the bolt, improve bolt strength, the load of equilibrium distribution on the bolt axis reduces the screw thread load of first to three circle, thereby prolongs bolt working life, bolton is good, strengthens the Security of vehicle.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of counterweight balance formula tire bolt assembly comprises bolt, nuts and washers, and described packing ring is made up of first packing ring and second packing ring, and sphere cooperates between described first packing ring and second packing ring.
Further, be assemblied on the nut, two packing rings are positioned at nut end described first packing ring and the second packing ring kink, and the outside end face of second packing ring is positioned at outside the same side end face of nut.Nut end contracts in second packing ring, and the outside end face of second packing ring is contacted with wheel.
Further, described first packing ring has the annular outer sphere, and described second packing ring has concave spherical surface in the annular with matching.
Further, the end of described nut forms flange by turning over riveting, thereby first packing ring and second washer sets are contained on the nut.Nut forms flange in the end after turning over riveting, and flange carries out axial limiting, and first packing ring and second washer sets are contained on the nut.
The utility model improves the nut collar on the bolt, packing ring is made up of first packing ring and second packing ring, sphere cooperates between first packing ring and second packing ring, make and to carry out the self adaption adjustment by sphere between two packing rings, 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, improve bolt strength, and the load that is subjected to of balanced bolt, thereby prolonged bolt working life, bolton is good, strengthens the Security of vehicle.
The beneficial effects of the utility model are: reduced the addition bend load on the bolt, improved bolt strength, the load of equilibrium distribution on the bolt axis, reduce the screw thread load of first to three circle, thereby prolong bolt working life, bolton is good, strengthens 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 counterweight balance formula tire bolt assembly comprises bolt 1, nut 2 and packing ring, and described packing ring is made up of first packing ring 3 and second packing ring 4, and sphere cooperates between described first packing ring 3 and second packing ring 4.Be assemblied on the nut 2 described first packing ring 3 and second packing ring, 4 kinks, described first packing ring 3 has the annular outer sphere, described second packing ring 4 has concave spherical surface in the annular with matching, two packing rings are positioned at nut 2 ends, and the outside end face of second packing ring 4 is positioned at outside the same side end face of nut 2.As can see from Figure 1, the underpart of described nut 2 has step 21 and assembling cylinder, first packing ring 3 is positioned on the assembling cylinder, the lower end of nut 2 forms taper flange 22 by turning over riveting, the end inner ring surface of the taper flange 22 and second packing ring 4 is adaptive behind riveted, thereby first packing ring 3 and second packing ring 4 are assembled on the nut 2, have the gap between first packing ring 3 and second packing ring 4 and the nut 2, thereby first packing ring 3 and second packing ring, 4 kinks are on nut 2.
Claims (4)
1. a counterweight balance formula tire bolt assembly comprises bolt, nuts and washers, and it is characterized in that: described packing ring is made up of first packing ring and second packing ring, and sphere cooperates between described first packing ring and second packing ring.
2. counterweight balance formula tire bolt assembly according to claim 1 is characterized in that: be assemblied on the nut, two packing rings are positioned at nut end described first packing ring and the second packing ring kink, and the outside end face of second packing ring is positioned at outside the same side end face of nut.
3. counterweight balance formula tire bolt assembly according to claim 2, it is characterized in that: described first packing ring has the annular outer sphere, and described second packing ring has concave spherical surface in the annular with matching.
4. according to described any counterweight balance formula tire bolt assembly of claim 1 to 3, it is characterized in that: the end of described nut forms flange by turning over riveting, thereby first packing ring and second washer sets are contained on the nut.
