Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, specifically to a wheel hub brake disc connection form for a wheel-side reduction axle. Background Technology

[0002] Wheel-side reduction axles are widely used in modern commercial vehicles due to their advantages such as high load-bearing capacity, high driving efficiency, strong adaptability, and convenient maintenance. With the increasing application of disc brakes in the market, the connection form between the wheel hub assembly and the brake disc of wheel-side reduction disc axles is receiving more and more attention.

[0003] The existing wheel-side reduction disc axle has the following shortcomings that need improvement: Since the wheel-side reducer gear is installed on the wheel hub assembly side, the gear requires continuous lubrication. When the conventional wheel hub assembly is connected to the brake disc, bolts are inserted from the wheel hub assembly side and screwed into the brake disc connection hole. Gear oil will seep along the connection bolt hole to the brake disc side, which will lead to oil seepage in the wheel-side part, affecting braking and poor lubrication of the wheel-side reducer.

[0004] Therefore, those skilled in the art have provided a hub brake disc connection method for wheel-side reduction axles to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a wheel hub brake disc connection form for wheel-side reduction axles, so as to solve the problem that the existing brake disc installation structure mentioned in the background art is not convenient enough and is prone to lubricating oil leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hub brake disc connection form for a wheel-side reduction axle, comprising a hub assembly, a stop provided on the outer side of the hub assembly, a flange provided on the outer side of the stop, a wheel-side reduction housing provided on the left side of the hub assembly, the edge of the wheel-side reduction housing being fixedly connected to the flange, and a brake disc provided on the right side of the hub assembly, the brake disc being connected to the stop.

[0007] Furthermore, the stop is integrally connected to the hub assembly, and the flange is integrally connected to the stop.

[0008] Furthermore, a sealing groove is provided on the outer side of the stop, the sealing groove is located on the left side of the flange, a sealing ring is installed in the sealing groove, and the edge of the wheel-side reduction housing is pressed against the sealing ring to form a sealed connection.

[0009] Furthermore, a threaded blind hole is provided on the right side of the stop, and a light hole is provided on the brake disc. A connecting bolt that connects to the threaded blind hole is installed in the light hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: This utility model facilitates the installation of the wheel-side reduction housing and brake disc through the provided stop and flange. This structure also prevents the lubricating oil in the wheel-side reduction housing from leaking out through the bolt holes and the wheel-side part from seeping oil, thereby solving the problem of oil leakage affecting braking and poor lubrication of the wheel-side reducer.

[0013] 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.

[0014] This utility model embodiment provides a hub brake disc connection form for a wheel-side reduction axle, including a hub assembly 1, a stop 2 provided on the outer side of the hub assembly 1, a flange 3 provided on the outer side of the stop 2, a wheel-side reduction housing 4 provided on the left side of the hub assembly 1, the edge of the wheel-side reduction housing 4 being fixedly connected to the flange 3, and a brake disc 5 provided on the right side of the hub assembly 1, the brake disc 5 being connected to the stop 2.

[0015] In this embodiment, the stop 2 is integrally connected to the hub assembly 1, and the flange 3 is integrally connected to the stop 2. Both the stop 2 and the flange 3 are obtained by CNC machining the outer side of the hub.

[0016] In this embodiment, a sealing groove 6 is provided on the outer side of the stop 2. The sealing groove 6 is located on the left side of the flange 3. A sealing ring 7 is installed in the sealing groove 6. The edge of the wheel-side reduction housing 4 squeezes the sealing ring 7 to form a sealed connection.

[0017] In this embodiment, a threaded blind hole 8 is provided on the right side of the stop 2, and a light hole is provided on the brake disc 5. A connecting bolt 9 that is connected to the threaded blind hole 8 is installed through the light hole.

[0018] Working principle: The brake disc 5 is connected to the edge of the flange 3 through the set stop 2. The connection method can be to set a buckle or install bolts, etc. The installation is relatively simple. At the same time, the set threaded blind hole 8 fixes the brake disc 5 to the stop 2, preventing the lubricating oil in the wheel-side reduction housing 4 from leaking out.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
