Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive bearing housing technology, specifically a novel automotive bearing housing. Background Technology
[0002] Automotive bearing races are a core component of automotive bearing systems. Working in conjunction with rolling elements, they are key structural components for realizing the bearing's rotational function and transmitting loads. They are widely used in core assemblies such as wheels, transmissions, engines, and steering systems. Structurally and materially, they are typically ring-shaped metal components with precise raceways on the inner or outer ring to provide a stable rolling trajectory for the rolling elements. The material is mostly high-carbon chromium bearing steel, which undergoes precision machining such as quenching and grinding to achieve high hardness, high wear resistance, and good dimensional stability, ensuring that it is not easily deformed or worn when subjected to radial and axial loads over a long period of time.
[0003] For example, an automotive bearing housing with application number CN202321572625.6 belongs to the technical field of bearing housings. This automotive bearing housing includes an adjusting assembly and a fixing assembly. The adjusting assembly includes a base plate, a fixing cylinder, a rotating rod, a gear ring assembly, an internal gear ring, and a limiting component. The fixing cylinder is fixedly connected to the top of the base plate. The fixing assembly includes a lower fixing seat and an upper fixing seat. The lower fixing seat is fixedly connected to the top of the rotating rod, and the upper fixing seat is disposed on top of the lower fixing seat. By setting the base plate, fixing cylinder, rotating rod, gear ring assembly, internal gear ring, and limiting component, the angle of the fixing assembly can be rotated and adjusted, and then positioned and fixed, thereby adjusting and adapting to the direction of the rotating shaft, realizing multi-level adjustment of direction, and improving practicality. The lower and upper fixing seats are used to install and fix the bearing and facilitate rotation. However, the bearing housing ring seal is prone to internal contamination, has difficulty withstanding alternating loads, is difficult to adapt to complex working conditions, and the bearing housing ring lubrication is easily affected by working conditions, making maintenance inconvenient, lubrication inaccurate, and service life short.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a new type of automotive bearing race. Utility Model Content

The protective reinforcement mechanism is fixedly connected to the inside of the inner bearing race, and the protective reinforcement mechanism includes a labyrinth-type sealing groove fixedly connected to the inner wall of the inner bearing race. A sealing rubber strip is fixedly connected to the inner wall of the labyrinth-type sealing groove, and a reinforcing rib is fixedly connected to the inner surface of the inner bearing race. A lightweight alloy filler block is embedded on one side of the reinforcing rib, and a surface strengthening coating is fixedly connected to the outer surface of the inner bearing race.
[0007] Preferably, the inner surface of the bearing inner ring is provided with rolling elements, and the outer surface of the rolling elements is fixedly connected with a buffer pad layer.
[0008] Preferably, the outer surface of the buffer pad is rotatably connected to the outer ring of the bearing, and the outer surface of the outer ring of the bearing is fixedly connected to a self-lubricating mechanism.

[0011] Preferably, the bottom of the outer ring of the bearing is fixedly connected to a mounting base, and the mounting base has a mounting hole inside.
[0012] Preferably, a gasket is fixedly connected to the top of the mounting hole, and an anti-slip layer is fixedly connected to the bottom of the mounting base.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of a protective reinforcement mechanism, forms the core of the automotive bearing housing ring for adapting to different working conditions. In addition to basic sealing, strength improvement, and wear-resistant protection functions, it relies on multiple interlaced annular grooves, alloy composite structure, titanium nitride coating, and other designs to further achieve the composite value of resisting working condition disturbances, lightweight energy saving, and multi-dimensional protection. It is adapted to complex scenarios such as high-frequency vibration, temperature fluctuation, and oil contamination during vehicle operation, reducing bearing contamination caused by single seal failure. The reinforcing ribs and alloy filler blocks form a stress dispersion network, which can evenly transmit the alternating loads generated by frequent starts and stops and rapid acceleration and deceleration of the vehicle.

[0015] 2. This utility model, through the setting of a self-lubricating mechanism, forms the core of long-term lubrication guarantee for automotive bearing housings. In addition to basic functions such as oil supply, impurity filtration, and grease cleanliness assurance, it further achieves the combined value of anti-interference, high-efficiency maintenance, and precise lubrication by relying on the design of stainless steel oil reservoir, double-layer filter screen, and neodymium iron boron strong magnet. It is suitable for complex scenarios such as high-frequency vibration, sudden temperature changes, and long-cycle operation during vehicle operation. Through the functional extension of each component, the self-lubricating mechanism enables the bearing housing to not only meet basic lubrication needs, but also adapt to long-term and stable operation under complex automotive conditions, achieving a comprehensive improvement in more durable lubrication, more convenient maintenance, and less wear, significantly extending the service life of the bearing housing.
