Description

Technical Field

[0001] This utility model relates to the field of wheel hub assembly technology, specifically to high-efficiency sealing wheel hub bolts for new energy vehicles. Background Technology

[0002] In response to the call for energy conservation and emission reduction, new energy vehicles are becoming increasingly common. When new energy vehicles are driving on the road, tires and brakes are particularly important and directly affect driving safety. Tires need to be connected to the vehicle body via bolts through the wheel hub. Bolts are a type of automotive component that is used very frequently in the modern automotive field.

[0003] A search revealed that patent application number 202211266572.5 discloses a new energy vehicle wheel hub bolt, comprising a bolt body, the top outer side of which is threadedly connected to the middle of the inner wall of a top cover, a sealing gasket fixedly connected to the top of the bolt body, the bottom of the top cover being positioned on top of the sealing gasket, the bottom outer side of the bolt body being threadedly connected to the inner wall of a bottom cover, the bottom surface of the inner wall of the bottom cover being fixedly connected to the bottom surface of a rubber pad, the top surface of the rubber pad being positioned on the bottom surface of the bolt body, and a rubber ring being provided on the upper outer periphery of the bolt body. In this invention, by pressing the sealing gasket against the inner top of the top cover and the rubber ring against the top surface of the wheel hub, water is prevented from entering the gap between the bolt body and the wheel hub. Lubricating oil is added to the oil inlet and injected into the gap between the bolt body and the wheel hub through the through-hole and transverse hole for lubrication, making it easy to remove the bolt body from inside the wheel hub.

[0004] The aforementioned application documents demonstrate the assembly of the wheel hub through the configuration of various components. However, the existing bolts are all single-threaded bolts, which have limited stability and may affect the safety of the wheel hub during long-term rotation.

[0005] Therefore, we proposed a high-efficiency sealing wheel hub bolt for new energy vehicles. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-efficiency sealing wheel hub bolt for new energy vehicles, solving the problem of limited assembly stability and insufficient safety of existing one-way bolts.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency sealing wheel hub bolt for new energy vehicles, including a shaft disc and a wheel hub disc mounted thereon, wherein the shaft disc and the wheel hub disc are provided with threaded slots, and the shaft disc and the wheel hub disc are threadedly assembled by wheel hub bolts.

[0008] The hub bolts include inner bolts and outer bolts that are positioned opposite each other, and a hub retaining plate is fixedly welded between the inner bolts and the outer bolts;

[0009] The hub bolts are threaded onto the axle disc via internal bolts, and the outer end of the internal bolts is fitted with an internal nut. The outer end of the outer bolts in the hub bolts is fitted with an external nut.

[0010] As a preferred embodiment of this utility model, a pad is fitted on the outer wall of the shaft disk, and the pad is provided with screw holes that are opposite to those on the shaft disk and the hub disk.

[0011] The addition of a pad increases wear resistance, thereby enhancing its stability and practicality.

[0012] As a preferred embodiment of this utility model, the rear side wall of the shaft disc is provided with three sets of locking holes located outside the screw hole, and a locking block that matches the specifications of the locking holes is fixedly welded to the inner side wall of the inner nut.

[0013] The design of the locking holes and locking blocks facilitates the installation of the inner nut onto the rear side of the axle disc from the rear, and allows for stable assembly in conjunction with the rotation of the wheel hub bolts.

[0014] As a preferred embodiment of this utility model, the inner bolt and the outer bolt have opposite thread patterns, and a washer ring is fitted on the outer side of the outer bolt between the outer nut and the wheel hub disc.

[0015] The arrangement of inner and outer bolts in opposite directions enhances the assembly effect, while the use of washers further increases wear resistance and practicality.

[0016] As a preferred embodiment of this utility model, the hub plate is a regular hexagonal plate, and the hub disc is provided with regular hexagonal slots that are compatible with the specifications of the hub plate.

[0017] The wheel hub retainer plate increases the stability of the wheel hub disc when it is secured to the wheel hub bolts.

[0018] This utility model provides a high-efficiency sealing wheel hub bolt for new energy vehicles. It has the following beneficial effects:

[0019] This high-efficiency sealing wheel hub bolt for new energy vehicles, through the design of the inner nut structure, facilitates the installation of bolts at both the inner and outer ends, ensuring its stability. At the same time, the inner and outer nuts at both ends increase the overall safety of the wheel hub after assembly, solving the problem of limited stability and insufficient safety of existing one-way bolt assemblies.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency sealing wheel hub bolt for new energy vehicles, including a shaft disc 2 and a wheel hub disc 1 mounted thereon. Threaded slots are provided in the shaft disc 2 and the wheel hub disc 1. The shaft disc 2 and the wheel hub disc 1 are threadedly assembled by wheel hub bolts 4. The wheel hub bolt 4 includes an inner bolt 41 and an outer bolt 42 that are positioned opposite each other, and a wheel hub retaining plate 43 is fixedly welded between the inner bolt 41 and the outer bolt 42. The wheel hub bolt 4 is threadedly assembled on the shaft disc 2 by the inner bolt 41. An inner nut 5 is fitted to the outer end of the inner bolt 41, and an outer nut 6 is fitted to the outer end of the outer bolt 42 in the wheel hub bolt 4.

[0027] Among them, the high-efficiency sealing wheel hub bolt for new energy vehicles, through the setting of the inner nut 5 structure, facilitates the installation of the inner and outer ends to ensure its stability. At the same time, the setting of the inner nut 5 and the outer nut 6 at the front and rear ends can increase the safety of the overall wheel hub assembly, solving the problem of limited stability and safety of existing one-way bolt assembly.

[0028] Example 2: A pad 3 is fitted on the outer wall of the shaft disk 2, and the pad 3 has screw holes that are opposite to those on the shaft disk 2 and the hub disk 1; the pad 3 can increase the wear resistance, thereby increasing its stability and practicality.
