Description

Technical Field

[0001] This invention relates to the field of composite suspension technology, specifically to a rubber spring composite suspension and its processing method. Background Technology

[0002] Spring suspension is a common vehicle suspension system used to support and dampen vehicle shocks. It consists of springs, shock absorbers, and other connecting components. The advantages of spring suspension are that it provides good suspension performance and comfort. The springs can freely extend and retract according to road conditions, thereby reducing bumps and vibrations during vehicle operation. In addition, spring suspension has a certain adaptability to heavy-duty or differently loaded vehicles, and is relatively simple and easy to maintain.

[0003] The working principle of spring suspension is that the spring bears the weight of the vehicle body and provides support. The spring absorbs and releases the impact force caused by uneven road surface through compression and extension, so as to maintain the stability of the vehicle body and the ride comfort. The shock absorber plays the role of controlling and mitigating the vibration of the spring. The shock absorber converts the vibration of the spring movement into heat energy through the internal damping mechanism, reducing the vibration and bumps of the vehicle body. The shock absorber can also help maintain the contact between the wheel and the ground, providing better traction and handling performance.

[0004] During use, existing spring suspensions are prone to getting dirty water and accumulating mud inside. This dirt can not only corrode the suspension springs, but also seep into the shock absorbers, affecting their performance.

[0005] In summary, there is a need for a rubber spring composite suspension with better protective performance and its processing method. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] To address the technical problems in the background section, the following rubber spring composite suspension and its processing method are provided:

[0045] Combination Figures 1-9 As shown, the present invention provides a rubber spring composite suspension, including a strut 1, a shock absorber 11 at the top of the strut 1, a bottom spring seat 12 on the outer side of the strut 1, a shock-absorbing spring 13 on the top surface of the bottom spring seat 12, a buffer pad at the top of the shock absorber 11, a top spring seat 14 at the top of the buffer pad, and a fixing seat 15 for assembly and fixation at the top of the top spring seat 14. The top of the shock absorber 11 passes through the buffer pad, the top spring seat 14, and the fixing seat 15. A rubber protective sleeve 2 is provided on the outer side of the shock-absorbing spring 13; the rubber protective sleeve 2 on the outer side of the shock-absorbing spring 13 can protect the shock-absorbing spring from the outside of the shock-absorbing spring 13. 13. To prevent dirt from contacting the shock absorber spring 13; the rubber protective sleeve 2 has the same length as the shock absorber spring 13, and a threaded groove 22 is provided on the inner side of the rubber protective sleeve 2. The threaded groove 22 is engaged with the shock absorber spring 13. The bottom of the top spring seat 14 is engaged with the top of the rubber protective sleeve 2, and the top of the bottom spring seat 12 is engaged with the bottom of the rubber protective sleeve 2. Through the engagement of the threaded groove 22 on the inner side of the rubber protective sleeve 2 with the shock absorber spring 13, the rubber protective sleeve 2 protects the shock absorber spring 13 while being supported by the outside of the shock absorber spring 13, thereby improving the shock absorption and cushioning effect of the composite suspension.

[0046] A buffer cavity is formed between the rubber protective sleeve 2, the top spring seat 14, and the bottom spring seat 12. A vent hole 16 communicating with the buffer cavity is opened in the middle of the bottom spring seat 12. Through the buffer cavity formed inside the rubber protective sleeve 2, and in conjunction with the vent hole 16 opened on the bottom spring seat 12, the air inside the composite suspension can be squeezed out when the composite suspension is subjected to force, thereby further improving the buffering and shock absorption effect of the composite suspension.

[0047] In this embodiment, a sealing ring 21 is provided on the outer side of the bottom end of the rubber protective sleeve 2. The sealing ring 21 is inclined downward. A sealing area is formed between the inner side of the sealing ring 21 and the outer side of the bottom end of the rubber protective sleeve 2. The sealing area is in close contact with the outer side of the bottom spring seat 12. The sealing ring 21 provided on the outer side of the rubber protective sleeve 2 can cover the joint between the rubber protective sleeve 2 and the bottom spring seat 12, thereby improving the sealing performance of the rubber protective sleeve 2 and preventing dirt from seeping into the interior of the suspension.

[0048] Example 2

[0049] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0050] To address the problems existing in the background art, this embodiment provides a processing method for a rubber spring composite suspension:

[0051] The processing method includes the following steps:

[0052] S1, Fixed Suspension:

[0053] The suspension strut 1 is placed vertically above the processing table 3 of the processing device, and the bottom end of the strut 1 is clamped and fixed by the fixing component 5. After the strut 1 is fixed, it is moved to the bottom of the assembly mechanism 4 and waits for processing and assembly.

[0054] The specific steps of the above-mentioned fixed suspension are as follows: the support column 1 is placed between the first clamping seat 34 and the second clamping seat 35 above the processing table 3. Then, the first electric push rod 33 pushes the first clamping seat 34 to move on the processing plate 32 to clamp and fix the support column 1. After the support column 1 is fixed, the base 31 controls the processing plate 32 to rotate, so that the fixed support column 1 moves to the bottom of the assembly mechanism 4 to wait for processing and assembly.

[0055] S2, Place the spring:

[0056] During assembly, the support spring is placed on top of the support column 1, so that the support spring rests on the bottom spring seat 12 and is located outside the shock absorber 11.

[0057] S3, Assemble rubber protective sleeve 2:

[0058] When assembling the rubber protective sleeve 2, the support spring is fixed and limited by the inside of the support spring through the positioning mechanism so that the position of the support spring will not change. Then, the rubber protective sleeve 2 is placed at the bottom of the assembly mechanism 4. The assembly mechanism 4 drives the rubber protective sleeve 2 to move downward spirally so that the rubber protective sleeve 2 is assembled on the outside of the support spring.

[0059] The specific steps for processing and assembling the rubber protective sleeve 2 are as follows: the second electric push rod 71 drives the pressure block 72, pressure rod 73 and pressure plate 74 to move downward. At this time, the fixing component 5 below the pressure plate 74 will be between the rubber protective sleeve 2 and the shock absorber 11. Then the pressure plate 74 continues to apply force downward. The support plate 54 between the first fixing ring 51, the second fixing ring 52 and the third fixing ring 53 in the fixing component 5 will rotate outward and push the fixing push plate 55. At this time, the fixed push plates 55 arranged in a ring will support the fixing shock absorber spring 13 outward.

[0060] Then, the rubber protective sleeve 2 is placed inside the assembly cylinder 43, and the vertical plate 61 in the drive assembly 6 is used to control the assembly mechanism 4 to move downward through the electric slide rail 62 on the side. When the rubber protective sleeve 2 moves downward, the motor 44 drives the assembly ring 42 and the assembly cylinder 43 to rotate through the drive rod 45. In this way, the assembly cylinder 43, which rotates downward, can assemble the rubber protective sleeve 2 on the outside of the shock-absorbing spring 13.

[0061] S4. Assemble the suspension:

[0062] After the rubber protective sleeve 2 and the support spring are processed and assembled, the top spring seat 14 is fastened to the rubber protective sleeve 2 and the top of the support spring. Then, the top spring seat 14 is finally assembled and fixed by the fixing seat 15.

[0063] The specific steps of the suspension assembly are as follows: after the rubber protective sleeve 2 and the shock absorber spring 13 are processed and assembled, the assembly mechanism 4 and the fixing component 5 move upward and separate from the shock absorber spring 13 and the rubber protective sleeve 2. Then, the base 31 drives the processing plate 32 to rotate, so that the strut 1, the shock absorber spring 13 and the rubber protective sleeve 2 move to a suitable assembly position. Then, the buffer pad, top spring seat 14 and fixing seat 15 and other components required for suspension assembly are fixed above the shock absorber 11.

[0064] Example 3

Through the rotatable connection between the assembly ring 42 and the assembly plate 41, the rubber protective sleeve 2 can be assembled on the outside of the shock-absorbing spring 13 by rotation during assembly. The motor 44 located on the side of the assembly plate 41 can provide power for the rotation of the assembly ring 42 and the assembly cylinder 43 through the drive rod 45.

[0070] In this embodiment, the assembly cylinder 43 has an elastic structure, and anti-slip strips 46 are provided on the inner side of the assembly cylinder 43.
