Description

Hub insert Technical Field The utility model relates to the technical field of hub inserts, in particular to a hub insert. Background The automobile hub insert is widely applied to improving the attractiveness and individuality of the hub as an important part of automobile appearance decoration. In the actual assembly process, the hub insert needs to be tightly combined with the hub, so that not only the mechanical requirements of vibration, centrifugal force and the like during running of the vehicle are met, but also the convenience in installation and the stability in long-term use are considered, and the structural design directly influences the decoration effect and the service life. However, the existing automobile hub insert has the defects that the traditional insert is mainly fixed by adopting a simple buckle or single-point contact, stress concentration is easy to cause, looseness and even falling occur under the driving vibration of a vehicle, driving safety is affected, and part of the insert lacks an effective load dispersing structure, is difficult to resist complex external force, so that the surface of the insert is deformed and worn, and decoration integrity is damaged. In addition, the dust problem in the technological process is not considered in the existing inserts, dust is easy to accumulate in the inserts in the procedures of spraying, cleaning and the like, the attaching precision and the attractiveness are affected, the cleaning is complicated, the maintenance cost is high, and the dual requirements of modern automobiles on the reliability and the attractiveness of the decorating parts cannot be met. Disclosure of Invention In order to solve the problems, the application provides a hub insert which is provided with an insert body, wherein the insert body is integrally fan-shaped, a fixing unit is arranged at the contact surface of the insert body and a hub, the fixing unit comprises two fixing support legs, clamping tables are arranged at the outer sides of the two fixing support legs, the clamping tables are arc-shaped in contact surface with the hub, a triangular support column is arranged between the two fixing support legs, and a support connecting plate is arranged between the triangular support column and the fixing support legs. In one embodiment, the side, close to the center of the hub, of the insert body is a tip contact portion, and the side, far away from the center of the hub, of the insert body is an arc contact portion, a diversion trench penetrating through the insert body is arranged in the middle of the insert body, and the arc contact portion is recessed towards the bottom of the center of the diversion trench in a transition mode. In one embodiment, a lock nut is arranged on the contact surface of the insert body and the hub, and a threaded hole of the lock nut is coaxial with the hub locking hole. In one embodiment, at least three reinforcing ribs are arranged on the contact surface of the insert body and the hub, the reinforcing ribs comprise two transverse reinforcing ribs and one radial reinforcing rib, the transverse reinforcing ribs and the radial reinforcing ribs are distributed in a cross staggered mode, and two ends of one transverse reinforcing rib are connected with the locking nut.
