[0003] However, in the actual use of this utility model, only the cylinder of the guide positioning sleeve gasket is inserted into the gap between the screw rod and the wheel disc, and the screw rod only plays a point support role for the wheel hub. The spaces are still not on the same axis, and then produce a cyclic shearing effect on the screw, and the screw is easy to break

Embodiment Construction

[0049] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.

[0050] A kind of firm tire bolt of the present invention, as Figure 1-7 As shown, it includes matching screw rod 1 and nut 2.

[0051] The screw 1 includes a rod head 11 and a rod post 12. The rod post 12 includes an unthreaded light column section 121 that is closer to the rod head 11 and a threaded column section 122 that is farther away from the rod head 11 and has a first external thread; The support sleeve 123 on the screw rod 1 and the anti-loosening device 124 for positioning the nut 2; the light column section 121 is formed with a first thick section 1211 with a thicker diameter and closer to the rod head 11, and a thinner diameter section 1211 farther away from it. The first thin-diameter section 1212 of the rod head 11; between the first thick-diameter section 1211 and the first thin-diameter section 1212, a tapered colum...

Abstract

The invention provides a firm tire bolt. In actual use, a screw of a bolt first passes through corresponding wheel holes of a wheel shaft connecting part and a hub connecting part of a tire, a supporting sleeve sleeves the screw, the screw is locked by tightening a nut; when the nut is tightened, the abutting end of an abutting sleeve abuts against and is connected with a second protruding portionof an inner sleeve, a cone column section abuts against a first protruding portion of the inner sleeve, an initial state of the supporting sleeve is that the first protruding portion and the second protruding portion of the inner sleeve are cocked up; after the nut is tightened, the first protruding portion and the second protruding portion are cocked up more significantly and abut against holesin the wheel shaft connecting part and the hub connecting part respectively, so that balance supporting is performed on the wheel shaft connecting part and the hub connecting part, and the breakage cause by the generation of shear stress due to the shaking of the screw in the hole in the tire rotating process is avoided.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a firm tire bolt. Background technique [0002] At present, it is known that in order to facilitate the disassembly and assembly of the wheel, the screw diameter of the automobile tire bolt assembly is 4-6mm smaller than the diameter of the wheel bolt hole, and the contact end surface of the tire nut and the tire is a plane and is parallel to the wheel plane. The final result is: ①When the wheel is installed on the hub, the wheel itself moves down vertically under the action of gravity. Due to the above-mentioned factors of hole and screw diameter difference, the centerline of the hub and the centerline of the wheel cannot be on the same axis, resulting in Irregular motion as the wheel spins. ②The torque transmission route when the car is running is: the torque is transmitted to the tire bolts through the hub, and then to the wheel disc (ie the wheel). Due to the difference in the dia...
