Vehicle wheel

Abstract

The invention discloses a vehicle wheel which comprises a hub, a spoke, a braking element and fastening connection components, wherein each fastening connection component is composed of a screw rod and a rotation retaining sleeve; the screw rods fix the hub, the spoke and the braking element together; the spoke is provided with first rotation retaining holes; a fetching structure used for fetching each rotation retaining sleeve which is installed out of a locking nut and in the corresponding first rotation retaining hole is arranged on the wall of each first rotation retaining hole and / or each rotation retaining sleeve; each rotation retaining sleeve is installed out of a rotation retaining holding part of the corresponding screw rod and in the corresponding first rotation retaining hole; a third rotation retaining part of a first rotation retaining through hole of each rotation retaining sleeve is matched with a fourth rotation retaining part arranged outsides the corresponding rotation retaining holding part to restrain rotation of the corresponding screw rod relative to a corresponding first rotation retaining sleeve; a second rotation retaining part arranged at the periphery of each rotation retaining sleeve is matched with a first rotation retaining part of the corresponding first rotation retaining hole to restrain rotation of the corresponding first rotation retaining sleeve relative to spoke; and the screw rods and the spoke are installed together without capability of rotation. The vehicle wheel has the advantages that a threaded connection pair cannot get loose due to reversed rotation, so that threaded connection is kept at a locking position which is initially needed and is reliable, and fetching of the rotation retaining sleeves is convenient and reliable.

Description

Technical field: [0001] The invention relates to a wheel; in particular, it relates to a fastening connection assembly of the wheel. Background technique [0002] The thread pair mechanical static connection between objects often encounters safety problems and safety accidents caused by the breakage of the bolts connected to some key parts and the failure of the threaded connection. It is a common problem faced by the world, and it is also an urgent need for continuous research and improvement by technicians in this field. Solve problems that have not been solved. Small bolts, big accidents, major accidents often occur due to bolt breakage, such as cylinder smashing accidents caused by breakage of connecting rod bolts of automobile engines; on April 18, 2009, 1 death and 4 injuries were caused by the breakage of Harbin tower crane bolts; according to China Taiwan media reported that the No. 1 reactor of the No. 2 Nuclear Power Plant detected seven anchor bolts that were bro...

Problems solved by technology

[0013] Aiming at the problems existing in the prior art, the technical problem to be solved by the present invention is to overcome the existing anti-loosening technology that those skilled in the art believe that the anti-loosening sleeve is used to restrict the rotation of the nut relative to the screw to realize the reverse loosening of the bolt and nut. Solution, because the anti-rotation sleeve is difficult or impossible to take out from the first anti-rotation hole, resulting in inertial thinking of no use value, the present invention provides a wheel, which uses a anti-rotation sleeve to limit the relative rotation of the threaded pair, so that the threaded pair cannot It will be loosened due to reverse rotation and the anti-rotation sleeve can be taken out from the first anti-rotation hole quickly, conveniently and reliably, so that the detachment of the screw, nut, etc. is fast, convenient and reliable.
