Abstract
The utility model discloses a novel hub nut, comprising a nut, a movable gasket, and further an anti-loosening gasket, wherein the nut is connected with one end of the movable gasket along the axial direction, a pair of spherical surfaces in convex-concave engagement are provided on one end of the anti-loosening gasket along the axial direction and the corresponding end of the movable gasket, and anti-loosening teeth is provided on the surface of the other end of the anti-loosening gasket along the axial direction. During assembling, when vertical deviation is caused by the hub bolt, the hub nut has function of automatic positioning through the spherical adhesion surface between the anti-loosening gasket and the movable gasket, so that the pressure center is kept on the axial line of the hub bolt after tightening of the nut, and the thread has homogeneous stress. And anti-loosening teeth are added on the surface of the other end of the anti-loosening gasket along the axial direction, friction between the surfaces of the anti-loosening gasket and the rub can be increase, the anti-loosening gasket can be firmly adhered to the surface of the hub, so that the locking reliability of the hub bolt assembly is enhance, and the service life of the hub bolt assembly is effectively prolonged.
Description
Technical field
The utility model relates to the bolt combination part that a kind of vehicle hub is used, particularly a kind of hub nut.
Background technique
When truck travels on abominable mining area, road surface, building site road, jolt and to produce great shearing force to the automotive hub bolt when vibration and brake are impacted, thereby cause tire bolt to fracture, shortened the working life of boss bolt assembly, the driver needs often to change whole boss bolt assembly like this; But change boss bolt continually, cause each bolt hole of wheel hub to produce different distortion, increasing easily, make bolts assemblies produce position degree, perpendicularity deviation, thereby cause the reliable lock of boss bolt assembly relatively poor, under this situation, must cause the stressed irregular of each boss bolt, and the bolt assembly of stressed maximum is damaged, thereby shorten the working life of boss bolt assembly, the driver can only change wheel hub like this, has increased maintenance expenses.
The model utility content
The purpose of this utility model provide a kind of reliable lock strong, prolong the boss bolt assembly novel hub nut in working life.
The technical solution of the utility model is such: a kind of novel hub nut, comprise nut and driving washer, nut is with an axial end socket of driving washer, also comprise lock washer, an axial end and the corresponding end of above-mentioned driving washer of above-mentioned lock washer is provided with a pair of concavo-convex sphere that cooperates, and the end face of the axial the other end of above-mentioned lock washer is provided with locking tooth.
The end face of above-mentioned lock washer and the contacted axial end of described driving washer is the outer spherical surface of projection, and the corresponding end face of above-mentioned driving washer be the recessed inner ball surface with the outer spherical surface of described projection activity tabling.
The end face of above-mentioned lock washer and the contacted axial end of above-mentioned driving washer is recessed inner ball surface, and the corresponding end face of above-mentioned driving washer is the outer spherical surface with the projection of above-mentioned recessed inner ball surface activity tabling.
Above-mentioned locking tooth is evenly distributed on the end face of the axial the other end of lock washer, and the profile of tooth of above-mentioned locking tooth is a right-angled triangle, and the hypotenuse direction of locking tooth is identical with the tightening direction of nut.
After adopting technique scheme, a kind of novel hub nut of the present utility model, have additional lock washer on the axial other end of driving washer, lock washer is provided with a pair of concavo-convex sphere that cooperates with driving washer, and the end face of the axial the other end of lock washer is provided with locking tooth.Compared with prior art, the faying surface of lock washer and driving washer is a sphere, has automatic positioning action, pressure center behind the nut screwing clamping can be remained on the shaft axis of boss bolt, thereby make screw thread stressed evenly, and on the axial other end of lock washer, set up locking tooth, can increase the frictional force between lock washer and hub surface, lock washer can be adjacent to securely on the surface of wheel hub, thereby increased the reliable lock of boss bolt assembly, can effectively improve the working life of boss bolt assembly; Because the profile of tooth of locking tooth is a right-angled triangle, and the hypotenuse direction of locking tooth is identical with the tightening direction of nut, nut is being tightened, can not finished when lock washer and then rotates in the release process and hurt compacted hub surface like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
A kind of novel hub nut of the present utility model, as Fig. 1, shown in 2, comprise nut 1, driving washer 2 and lock washer 3, nut 1 connects together with an axial end of driving washer 2, lock washer 3 is provided with cavity 31 with driving washer 2 contacted axial ends, the chamber face of cavity 31 is recessed inner ball surface, the axial the other end corresponding site of lock washer 2 is provided with the protuberance 21 suitable with cavity 31, the outer surface of protuberance 21 is the outer spherical surface of projection, be evenly distributed with some locking teeth 32 on the end face of the axial the other end of lock washer 3, the profile of tooth of locking tooth 32 is a right-angled triangle, and the hypotenuse bearing of trend of right-angled triangle is identical with the tightening direction of nut 1.
When assembling, when boss bolt produces perpendicularity deviation, faying surface by lock washer 3 and driving washer 2 is a sphere, it has automatic positioning action, pressure center behind the nut screwing clamping can be remained on the shaft axis of boss bolt, thereby make screw thread stressed evenly, and on the end face of the axial the other end of lock washer 3, set up locking tooth 32, can increase the frictional force between lock washer 3 and hub surface, lock washer 3 can be adjacent to securely on the surface of wheel hub, thereby increased the reliable lock of boss bolt assembly, can effectively improve the working life of boss bolt assembly; Because the profile of tooth of locking tooth 32 is a right-angled triangle, and the hypotenuse direction of locking tooth 32 is identical with the tightening direction of nut, nut is being tightened, can not finished when lock washer 3 and then rotates in the release process and hurt compacted hub surface like this.
In the utility model, also can be the outer spherical surface of projection with the end face of lock washer 3 and driving washer 2 contacted axial ends, the corresponding site of driving washer 2 is provided with the suitable cavity of outer spherical surface with projection, and the chamber face of cavity is recessed inner ball surface, and it can reach the effect identical with embodiment.
