Anti-loose tire bolt

Abstract

The invention provides an anti-loose tire bolt which comprises a screw and a nut. The nut is provided with a movable washer; a flange is formed in an end of the nut; the movable washer is sleeved on the flange and is an open spring washer; the flange comprises a small-diameter section, a large-diameter section and an end section; the spring washer is rotatably sleeved on the small-diameter section; the outer diameter of the small-diameter section and the outer diameter of the end section are smaller than the inner diameter of the spring washer, the outer diameter of the large-diameter section is larger than the inner diameter of the spring washer, and a convenient oblique plane is formed on an end surface of the large-diameter section, so that the spring washer can be conveniently sleeved on the thin-diameter section via the convenient oblique plane. A structure form of the traditional anti-loose tire bolt is broken through, a middle hole of the spring washer corresponds to the convenient oblique plane during assembly, and the spring washer is conveniently pushed through the large-diameter section by the aid of the convenient oblique plane under the effect of stamping force of a machine, and is sleeved and limited on the small-diameter section. Compared with the prior art, the anti-loose tire bolt has the advantages of simplicity in assembly process, simple, novel and reasonable structure, excellent service performance and long service life.

Description

technical field [0001] The invention relates to bolts in the field of automobile tire components, in particular to an anti-loosening tire bolt. Background technique [0002] At present, it is known that in order to facilitate the disassembly and assembly of the wheel, the diameter of the screw in the automobile tire bolt assembly is 4-6mm smaller than the diameter of the corresponding bolt hole on the wheel hub, and the contact end surface of the tire nut and the wheel hub is a plane and parallel to the wheel hub plane. of. The result after the above bolt assembly is installed is: ①After the wheel is installed, due to the gravity and the factors of the diameter difference between the bolt hole and the screw rod, the centerline of the axle shaft and the centerline of the wheel cannot be on the same axis, resulting in irregular rotation of the wheel. ②The torque transmission route when the car is running is: the torque is transmitted to the bolt through the wheel disc, and th...

Problems solved by technology

However, this utility model also has defects in the actual use process, that is, after long-term use, the positioning table and the screw rod or the wheel bolt hole are stuck due to corrosion or deformation, causing the positioning tube gasket to be difficult to disassemble, and the connection strength between the nut and the positioning tube gasket It is not enough to pull out the positioning tube gasket together with the positioning table, and even the nut has been separated from the positioning tube gasket. At this time, it is difficult to remove the positioning tube gasket, which brings a lot of trouble to people. The reason is that the structure is lack of rationality, the structure Complicated, low strength; moreover, the processing technology of this utility model is cumbersome, the cost is high, and the practicability needs to be improved
