Abstract
Description
Technical Field
[0001] This utility model relates to the field of suspension bearing technology, and in particular to a high load-bearing capacity suspension bearing with selectable sealing methods. Background Technology
[0002] Suspension bearings are an important component of the automotive suspension system. They are located above the coil springs in the suspension system. The upper end of the suspension bearing is usually connected to the vehicle body through a top connecting plate. The force from the wheel is transmitted to the vehicle body through the coil springs and suspension bearings, so the suspension bearing needs to be able to withstand large axial forces.
[0003] Suspension bearings reduce friction through rolling motion. When the shaft starts to rotate, multiple rolling elements inside the bearing begin to roll. This rolling motion helps to reduce friction and reduce the consumption of rotational energy. Compared with the sliding motion of sliding bearings, rolling bearings are more effective at reducing friction.
[0004] Traditional suspension bearings typically have a single row of rolling elements, which can affect their load-bearing capacity. Furthermore, the limited sealing methods of suspension bearings can negatively impact their sealing performance.
[0005] Therefore, it is necessary to provide a high-load-bearing suspension bearing with optional sealing to solve the above-mentioned technical problems. Utility Model Content
[0006] This invention provides a high-load-bearing suspension bearing with selectable sealing methods, solving the problems of poor stability of single-row rolling element suspension bearings under load and the impact of a single sealing method on sealing performance.
[0007] To solve the above-mentioned technical problems, the high-load-bearing suspension bearing with optional sealing form provided by this utility model includes: an outer support;
[0008] The first inner slide is located on the inner surface of the outer support near the front. The second inner slide is located on the inner surface of the outer support near the back. The inner surface of the outer support near both the front and back is provided with a first sealing groove. The outer support has an inner ring inside. The outer surface of the inner ring is provided with a first outer slide and a second outer slide. The outer surface of the inner ring is provided with a second sealing groove near both ends. A set of rolling elements is installed between the first inner slide and the first outer slide through a first retainer. A set of rolling elements is installed between the second inner slide and the second outer slide through a second retainer. The front and back of the outer support are fixedly connected with internal threaded rings. The inner surface of the internal threaded rings is threaded with external threaded rings. One end of each external threaded ring is fixedly connected with a reinforcing ring.
[0009] A lower sealing ring is installed between the first sealing groove and the second sealing groove on the front side, and an upper sealing ring is installed between the first sealing groove and the second sealing groove on the back side.
[0010] The first and second inner slides are located between the two first sealing grooves. The external threaded ring can reduce the openings at both ends of the outer support and increase the stability of the rolling element inside the slide. The outer and inner surfaces of the lower and upper sealing rings are respectively inserted into the first and second sealing grooves.
[0011] Preferably, an injection pipe is installed on the outer surface of the outer support, and an oil storage pipe is threaded to the other end of the injection pipe;
[0012] The oil reservoir is filled with lubricant, which can be injected into the first lubrication channel and the second lubrication channel through the injection pipe.
[0013] Preferably, the inner surfaces of the first inner slide and the second inner slide are provided with a first lubrication channel, and the other end of the two first lubrication channels is connected to the second lubrication channel.
[0014] The second lubrication channel corresponds to the position of the injection pipe.
[0015] Preferably, a bracket is mounted on the outer surface of the outer support, and a plurality of mounting holes are provided on one side of the bracket;
[0016] The bracket can install the external support in the corresponding position.
[0017] Preferably, the outer support is provided with a support frame on both the front and back sides, and the other end of each of the two support frames is fixedly connected with a mounting ring;
[0018] The length of the support frame does not affect the installation of the external support.
[0019] Preferably, the inner surface of the mounting ring is provided with multiple slots, and the inner surface of the mounting ring is fitted with a bearing by means of a bolt;
[0020] The latch is inserted into the slot.
[0021] Compared with related technologies, the high-load-bearing capacity suspension bearing with optional sealing method provided by this utility model has the following advantages:
[0022] This invention provides a high-load-bearing suspension bearing with selectable sealing methods. To improve the load-bearing capacity and sealing performance of the suspension bearing, a first inner slide and a second inner slide are respectively formed on the inner surface of the outer support. Simultaneously, two first sealing grooves are formed on the inner surface of the outer support. A first outer slide and a second outer slide are formed on the outer surface of the inner ring. Two sets of rolling elements are installed between the first and second inner slides and the second inner and outer slides, respectively, via a first cage and a second cage. These two sets of rolling elements increase the load-bearing capacity of the suspension bearing. A second sealing groove and a first sealing groove are respectively formed near both ends between the inner ring and the outer support. An upper sealing ring and a lower sealing ring are respectively installed between the two sets of first and second sealing grooves, allowing for a closer fit between the upper and lower sealing rings and the inner ring and outer support, thus increasing the sealing performance. This design allows for the installation of upper and lower sealing rings of different forms and materials between the outer support and the inner ring. The use of the second and first sealing grooves does not reduce the sealing effect. Furthermore, the double-row design distributes the weight, increasing the load-bearing capacity of the suspension bearing during use. Attached Figure Description

The outer surface of the inner ring 5 is formed on both the front and back. The outer surface of the inner ring 5 is formed on both the front and back. The outer surface of the inner ring 5 is formed on both the front and back. A set of rolling elements 9 is installed between the first inner slide 12 and the first outer slide 20 through a first retainer 8. A set of rolling elements 9 is installed between the second inner slide 15 and the second outer slide 23 through a second retainer 17. The front and back of the outer support 1 are fixedly connected to an internal threaded ring 11. The inner surface of the internal threaded ring 11 is threadedly connected to an external threaded ring 10. One end of the external threaded ring 10 is fixedly connected to a reinforcing ring 4.

[0035] The first inner slide 12 and the second inner slide 15 are located between the two first sealing grooves 13. The external threaded ring 10 can reduce the openings at both ends of the outer support 1 and increase the stability of the rolling element 9 inside the slide. The outer and inner surfaces of the lower sealing ring 14 and the upper sealing ring 22 are respectively inserted into the first sealing groove 13 and the second sealing groove 21. Using sealing rings made of different materials will not affect the sealing performance.
[0036] An injection pipe 2 is installed on the outer surface of the outer support 1, and an oil storage pipe 3 is threaded to the other end of the injection pipe 2.
[0037] The oil reservoir 3 is filled with lubricant, which can be injected into the first lubrication channel 18 and the second lubrication channel 19 through the injection pipe 2.
[0038] The inner surfaces of the first inner slide 12 and the second inner slide 15 are each provided with a first lubrication channel 18, and the other end of the two first lubrication channels 18 is connected to the second lubrication channel 19.

[0041] The bracket 7 can install the outer support 1 in the corresponding position, and the mounting hole 6 is for easy bolt passage.
[0042] The working principle of the high-load-bearing suspension bearing with optional sealing method provided by this utility model is as follows:
[0043] A first inner slide rail 12 and a second inner slide rail 15 are respectively opened on the inner surface of the outer support 1. At the same time, two first sealing grooves 13 are opened on the inner surface of the outer support 1. A first outer slide rail 20 and a second outer slide rail 23 are opened on the outer surface of the inner ring 5. Between the first inner slide rail 12 and the first outer slide rail 20 and the second inner slide rail 15 and the second outer slide rail 23, two sets of rolling elements 9 are installed through the first retainer 8 and the second retainer 17 respectively. The two sets of rolling elements 9 can increase the load-bearing capacity of the suspension bearing.

In actual use, the weight brought by the inner ring 5 is evenly distributed by the two sets of rolling elements 9, increasing the stability of the inner ring 5.
[0044] Compared with related technologies, the high-load-bearing capacity suspension bearing with optional sealing method provided by this utility model has the following advantages:
[0045] To improve the load-bearing capacity and sealing performance of the suspension bearing, a first inner slide rail 12 and a second inner slide rail 15 are respectively formed on the inner surface of the outer support 1. Simultaneously, two first sealing grooves 13 are formed on the inner surface of the outer support 1. A first outer slide rail 20 and a second outer slide rail 23 are formed on the outer surface of the inner ring 5. Between the first inner slide rail 12 and the first outer slide rail 20 and the second inner slide rail 15 and the second outer slide rail 23, two sets of rolling elements 9 are installed via a first cage 8 and a second cage 17, respectively. These two sets of rolling elements 9 increase the load-bearing capacity of the suspension bearing. The inner ring 5 and the outer support 1 are positioned near... A second sealing groove 21 and a first sealing groove 13 are respectively provided near both ends. An upper sealing ring 22 and a lower sealing ring 14 are installed between the two sets of first sealing grooves 13 and second sealing grooves 21, so that the upper sealing ring 22 and the lower sealing ring 14 fit more closely with the inner ring 5 and the outer support 1, thereby increasing the sealing performance. Through this design, upper sealing rings 22 and lower sealing rings 14 of different forms and materials can be installed between the outer support 1 and the inner ring 5. The second sealing groove 21 and the first sealing groove 13 will not reduce the sealing effect. At the same time, the double row of weight distribution increases the load-bearing capacity of the suspension bearing during use.
[0046] Second Embodiment
[0047] Please refer to the following: Figures 5-6 , Figure 5 A schematic diagram of the second embodiment of the high-load-bearing suspension bearing with optional sealing method provided by this utility model; Figure 6This utility model provides a structural schematic diagram of a retaining bolt. Based on the high-load-bearing suspension bearing with optional sealing method provided in the first embodiment of this application, the second embodiment of this application proposes a high-load-bearing suspension bearing with optional sealing method. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0048] Specifically, the difference in the high load-bearing capacity suspension bearing with optional sealing form provided in the second embodiment of this application is that the front and back of the outer support 1 are provided with support frames 24, and the other end of the two support frames 24 is fixedly connected with an installation ring 26.
[0049] The length of the support frame 24 does not affect the installation of the outer support 1.
[0050] The inner surface of the mounting ring 26 is provided with multiple slots 28, and the inner surface of the mounting ring 26 is fitted with a bearing 25 by means of a bolt 27;
[0051] When the retainer 27 is inserted into the groove 28, the bearing 25 can be fixed inside the mounting ring 26.
[0052] Compared with related technologies, the high-load-bearing capacity suspension bearing with optional sealing method provided by this utility model has the following advantages:
[0053] To increase the stability of the suspension bearing under load, a mounting ring 26 with a groove 28 is installed at both ends of the outer support 1 via a support frame 24. Then, two bearings 25 are installed in the mounting ring 26 via bolts 27. The two auxiliary bearings 25 increase the contact area between the shaft passing through the inner ring 5 and the suspension bearing. Without affecting the shaft rotation, this helps to improve the stability of the suspension bearing under load.
