Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to lightweight, high-strength automotive bearing housings. Background Technology

[0002] Automotive bearing housings are components used to support and secure bearings. As the connection structure between the bearing and the vehicle body or frame, they ensure the outer ring of the bearing remains stationary while allowing the inner ring to rotate, thus stably transmitting power and bearing various loads during vehicle operation. The function of bearing housings not only is to secure the bearing, but also to effectively distribute vehicle weight, reduce friction, and absorb some road vibrations, improving driving safety and comfort. As a key basic component supporting bearings, the performance of automotive bearing housings directly affects the reliability, lifespan, and overall vehicle energy efficiency of the transmission system or wheel hub unit.

[0003] Traditional automotive bearing housings are generally made of a single material such as cast iron or forged steel. Although they have sufficient strength, they are too heavy, which is not conducive to vehicle lightweighting and fuel economy. Furthermore, if the heat generated by the bearing during high-speed operation cannot be dissipated in time, it will accelerate the aging of the lubricating grease and cause bearing wear. Traditional bearing housings usually lack active heat dissipation design. In addition, when the inner hole surface that mates with the bearing is worn and the clearance exceeds the tolerance, the entire bearing housing assembly often needs to be replaced, resulting in high maintenance costs and waste of resources. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight and high-strength automotive bearing housing, thereby solving the problems mentioned in the background art, such as the bulky single-material structure affecting vehicle lightweighting, the lack of active heat dissipation design leading to easy overheating and wear of the bearing, and the high maintenance costs caused by the need for complete replacement after wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight, high-strength automotive bearing housing, comprising an outer shell, an inner bushing, and a lightweight intermediate layer. The edges at both ends of the outer shell are welded to the edges of the outer surface of the inner bushing. The inner bushing is disposed between the outer shell and the inner bushing. A spiral cooling channel is provided inside the inner bushing. A wear-resistant liner is provided on the inner surface of the inner bushing. A limiting plate is fixedly connected to the outer surface of one end of the wear-resistant liner. Multiple connecting rods are fixedly connected to the side of the limiting plate near the inner bushing. Anti-slip sleeves are fixedly connected to the outer surface of the connecting rods. A threaded portion is provided at the end of the connecting rod away from the limiting plate. A fastening sleeve is threadedly connected to the outer surface of the threaded portion.

[0006] Preferably, the outer surface of the inner bushing is provided with a plurality of radial reinforcing ribs, the radial reinforcing ribs being integrally formed with the inner bushing, the outer surface of the lightweight intermediate layer being connected to the inner surface of the outer shell by an adhesive, and the inner surface of the lightweight intermediate layer being connected to the outer surface of the inner bushing by an adhesive.

[0007] Preferably, the outer surface of the outer shell is provided with a plurality of mounting parts, the mounting parts are integrally formed with the outer shell, and both ends of the spiral cooling channel are fixedly connected with valve-equipped conduits.

[0008] Preferably, the inner bushing has multiple insertion holes and receiving grooves inside, the receiving grooves are located at one end of the insertion holes, and the interior of the receiving grooves is connected to the interior of the insertion holes.

[0009] Preferably, the outer surface of the anti-slip sleeve is adapted to the inner surface of the insertion hole, the threaded portion of the end of the connecting rod extends into the receiving groove, and the outer surface of the fastening sleeve is adapted to the interior of the receiving groove.

[0010] Preferably, the wear-resistant liner is fixedly installed on the inner surface of the inner liner by means of a limiting connecting plate, a connecting rod and a fastening sleeve. Beneficial effects

[0011] This utility model provides a lightweight, high-strength automotive bearing housing. It has the following beneficial effects:

[0012] 1. This lightweight and high-strength automotive bearing housing adopts a composite structure consisting of an outer shell, a lightweight aluminum alloy honeycomb intermediate layer, and an inner bushing with radial reinforcing ribs, and integrates a spiral cooling channel. This achieves a balance between lightweight and high strength in the bearing housing. The structure not only utilizes the excellent specific stiffness and damping characteristics of honeycomb materials to effectively absorb vibration and disperse stress, but also significantly reduces the bearing operating temperature through active liquid cooling circulation, thereby comprehensively improving load-bearing capacity, fatigue resistance, and service life.

[0013] 2. This lightweight, high-strength automotive bearing housing features a quick-release module consisting of a wear-resistant liner, a limiting plate, a connecting rod, and a fastening sleeve. This innovative design makes easily worn parts replaceable components. After the wear-resistant liner wears out, only this single module needs to be replaced, avoiding the scrapping of the entire bearing housing in the traditional way and greatly reducing the user's maintenance costs.

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.

[0019] like Figure 1-3 As shown, this utility model provides a lightweight, high-strength automotive bearing housing, including an outer shell 1, an inner bushing 2, and a lightweight intermediate layer 3. The edges at both ends of the outer shell 1 are connected to the edges of the outer surface of the inner bushing 2 by welding. The inner bushing 2 is disposed between the outer shell 1 and the inner bushing 2. A spiral cooling channel 6 is provided inside the inner bushing 2. A wear-resistant inner liner 8 is provided on the inner surface of the inner bushing 2. A limiting plate 9 is fixedly connected to the outer surface of one end of the wear-resistant inner liner 8. A plurality of connecting rods 10 are fixedly connected to the side of the limiting plate 9 near the inner bushing 2. An anti-slip sleeve 11 is fixedly connected to the outer surface of the connecting rod 10. A threaded part 12 is provided at the end of the connecting rod 10 away from the limiting plate 9. A fastening sleeve 13 is threadedly connected to the outer surface of the threaded part 12.

[0020] Specifically, the outer surface of the inner bushing 2 is provided with multiple radial reinforcing ribs 4, which are integrally formed with the inner bushing 2. The outer surface of the lightweight intermediate layer 3 is connected to the inner surface of the outer shell 1 by an adhesive, and the inner surface of the lightweight intermediate layer 3 is connected to the outer surface of the inner bushing 2 by an adhesive. The radial reinforcing ribs 4 play a role in enhancing structural rigidity and distributing load, and the integral forming ensures connection strength.

[0021] Specifically, the outer surface of the outer shell 1 is provided with multiple mounting parts 5, which are integrally formed with the outer shell 1. Both ends of the spiral cooling channel 6 are fixedly connected with valved conduits 7. The mounting parts 5 are used to reliably install the entire bearing housing onto the vehicle body. The valved conduits 7 facilitate connection to the external cooling system to realize the circulation of coolant.

[0022] Specifically, the inner bushing 2 has multiple insertion holes 14 and receiving grooves 15 inside. The receiving grooves 15 are located at one end of the insertion holes 14 and are connected to the inside of the insertion holes 14. The insertion holes 14 provide precise guidance and positioning for the connecting rod 10, and the receiving grooves 15 provide installation space for the fastening sleeve 13.

[0023] Specifically, the outer surface of the anti-slip sleeve 11 is adapted to the inner surface of the insertion hole 14, the threaded portion 12 at the end of the connecting rod 10 extends into the receiving groove 15, the outer surface of the fastening sleeve 13 is adapted to the interior of the receiving groove 15, the anti-slip sleeve 11 prevents the connecting rod 10 from sliding in the insertion hole 14, ensuring connection stability, and the threaded portion 12 and the fastening sleeve 13 cooperate to generate axial clamping force, achieving reliable connection and fixation.

[0024] Specifically, the wear-resistant liner 8 is fixedly installed on the inner surface of the inner bushing 2 through the cooperation of the limiting connecting plate 9, the connecting rod 10 and the fastening sleeve 13. This detachable connection structure allows the wear-resistant liner 8 to be replaced individually after wear.

[0025] The working principle of the above embodiments:

[0026] The bearing is installed in the inner hole of the wear-resistant inner liner 8. When the bearing operates, the radial load generated is first transferred to the inner bushing 2 through the wear-resistant inner liner 8. Multiple radial reinforcing ribs 4 on the outer surface of the inner bushing 2 are integrally formed with the inner bushing 2, which can effectively enhance the structural rigidity and distribute the load. The lightweight intermediate layer 3 is made of aluminum alloy honeycomb material. This porous honeycomb structure significantly reduces the overall weight while ensuring the load-bearing strength, and effectively absorbs and attenuates vibration energy through its unique structure. When the bearing generates heat at high speed, the coolant enters the spiral cooling channel 6 through the valved conduit 7 at one end, circulates inside the inner bushing 2, and then flows through the other end... The valved conduit 7 flows out, carrying away heat to achieve active heat dissipation. The wear-resistant inner liner 8 is fixedly installed on the inner surface of the inner bushing 2 through the cooperation of the limiting connecting plate 9, the connecting rod 10 and the fastening sleeve 13. The connecting rod 10 passes through the insertion hole 14 opened on the inner bushing 2. The anti-slip sleeve 11 ensures the connection stability. The threaded part 12 extends into the receiving groove 15. By tightening the fastening sleeve 13, an axial tensile force is generated, so that the limiting connecting plate 9 presses the end face of the wear-resistant inner liner 8 to form a reliable fixation. This detachable structure allows the wear-resistant inner liner 8 to be replaced individually by simply loosening the fastening sleeve 13 when it wears due to long-term use, without having to replace the entire bearing housing, which significantly reduces maintenance costs and time.
