Abstract
The utility model discloses an automobile tire hub bolt. The automobile tire hub bolt comprises a bolt bar and a bolt head, wherein rotating threads are arranged on both one end, close to the bolt head, of the bolt bar, and the other end, far away from the bolt head, of the bolt bar, and rotating directions of the two ends are opposite. According to the automobile tire hub bolt, in the actual assembling process of the automobile tire hub bolt and a nut, the bolt head can be fixed without using a tool, tensile strength and torsional strength of the bolt can be improved, the service life of the bolt is prolonged, safety of the bolt in the using process is improved, and safety of an automobile is improved.
Description
Technical field
The utility model belongs to the auto parts machinery field, relates to a kind of automobile tire wheel hub bolt.
Background technique
At present, design has straight thread 3 ' to bolt bolt shank 1 ' on the market near bolt head 2 ' one end, and the other end design has right-handed thread 4 '.Existing design bolt and automotive hub screw junction are straight thread, in the wheel bore wearing and tearing, cause bolt looseness easily, when automobile impacts in jolt vibration and brake, because irregular running can produce great shearing force to the automobile tire bolt, cause the tire bolt fracture, the bolt assembly is impaired, shortens the working life of tire bolt assembly.Simultaneously, after straight thread is directly fixed, do not have elasticity, the stress that automobile vibration produces is directly delivered to bolt head, causes metal fatigue easily, and there is potential safety hazard in fracture easily.On the other hand, existing design bolt is installed in practical application and is screwed in the nut process, needs the instrument anchor stud head because bolt shank can rotate.
Summary of the invention
The purpose of this utility model be to provide a kind of nut check convenient, do not need the instrument anchor stud head, long service life, safe automobile tire wheel hub bolt.
The technological scheme that the utility model adopts: a kind of automobile tire wheel hub bolt, comprise bolt shank and bolt head, the end that an end of the close bolt head of described bolt shank reaches away from bolt head has all designed the rotation screw thread, and both rotation directions are opposite.
Further, described bolt shank is left-handed thread near the rotation screw thread of the first end of bolt, is right-handed thread away from the rotation screw thread of the first end of bolt, is more suitable for user's use habit.
Further, described rotation screw thread near the first end of bolt is square threaded form, and described square threaded form makes that working bolt is steady, efficient is high, effectively eliminates stress, anti impulsion load.
Further, thread bottom land angle and the thread drift angle of described square threaded form are designed to circular arc, and be more attractive in appearance.
The beneficial effects of the utility model:
The utility model is by the rotation screw thread design mutual reverse to the bolt shank two ends, make in the nut lockk bolt that turns clockwise, because thread rotary orientation opposite bolt shank in the left and right sides can not followed nut to rotate and rotate, need not by the instrument anchor stud head, directly just can pass through rotation nut check, and improved tensile strength and the twisting strength of bolt, be not easy to fracture, prolong bolt working life, strengthen the Security of the Security, particularly load-carrying vehicle of vehicle.

Fig. 2 is the plan view of the utility model bolt;
Fig. 3 is the utility model Fig. 2 A portion partial enlarged drawing.
Annotate: 1 bolt shank; 2 bolt heads; 3 rotation screw threads; 31 left-handed threads; 32 right-handed threads; 4 screw thread teeth groove; 5 threads.
Embodiment
A kind of automobile tire wheel hub of the utility model bolt comprises bolt shank 1 and bolt head 2, and the end that an end of described bolt shank 1 close bolt head 2 reaches away from bolt head 2 has all designed rotation screw thread 3, and both rotation directions are opposite.
Further, described bolt shank 1 is left-handed thread 31 near the rotation screw thread 3 of bolt head 2 one ends, is right-handed thread 32 away from the rotation screw thread 3 of bolt head 2 one ends, is more suitable for user's use habit.
Further, described rotation screw thread 3 near the first end of bolt is square threaded form, and described square threaded form makes that working bolt is steady, efficient is high, effectively eliminates stress, anti impulsion load.
Further, screw thread teeth groove 4 base angles and thread 5 drift angles of described square threaded form are designed to circular arc, and are more attractive in appearance.
The utility model is by increasing bolt length to original bolt design mutual reverse rotation screw thread and prolongation polished rod, solve bolt and nut and screwed a difficult problem that needs the instrument anchor stud head, bolt tension and twisting strength have also been improved, prolong the working life of bolt, improved the Security that bolt uses.
The above only is preferred embodiment of the present utility model, and all impartial conversion and modifications of doing according to the utility model claim all belong to the covering scope of the utility model patent.
