Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle hydraulic suspension. Background Technology

[0002] The suspension structure is a crucial component of a car. Ideally, the suspension should effectively dampen low-frequency, high-amplitude vibrations caused by road surface and engine idling. Therefore, it needs to possess high damping and high stiffness at low frequencies; conversely, to reduce cabin noise and improve maneuverability, it needs low damping and low stiffness at high frequencies. Thus, the suspension needs to possess both of these characteristics. However, existing rubber suspensions exhibit significant dynamic hardening beyond their high-frequency range, which is detrimental to improving ride comfort.

[0003] Application CN 112128298 A discloses a vehicle hydraulic suspension structure and automobile, including a carrier, a main spring, an outer tube, and a bottom sealing plate. The carrier is retractably and vertically inserted into the main spring, the outer tube is sleeved on the main spring, and the bottom sealing plate is disposed at the lower end of the main spring inside the outer tube and abuts against the edge of the main spring. The outer tube and the main spring enclose a sealed liquid chamber. In the vehicle hydraulic suspension structure of this embodiment, a baffle is provided at the lower end of the carrier, which divides the sealed liquid chamber into upper and lower liquid chambers. During vibration, the liquid flows between the upper and lower liquid chambers through the flow channel, thereby generating hydraulic characteristics for flexible vibration damping. When pressed down, the baffle descends, and the liquid flows from the lower liquid chamber into the upper liquid chamber; conversely, it flows into the lower liquid chamber, thereby generating corresponding damping. The baffle moves up and down in the sealed liquid chamber, thus forming greater damping and a higher peak hysteresis angle, resulting in a better riding experience.

[0004] The aforementioned structure lacks a separate cover plate for positioning the sliding rod and mounting plate, which is not conducive to combined installation and positioning. Furthermore, it lacks a damping piston for setting through holes and inclined holes, making it impossible to adjust the flow rate as needed to adapt to different damping effects. This results in poor adaptability and requires improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vehicle hydraulic mount to solve the problems that existing hydraulic mounts cannot be installed in separate parts and cannot adjust the damping effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle hydraulic suspension, comprising a fixing plate, an mounting cylinder fixedly connected to the upper surface of the fixing plate, a threaded cylinder threadedly installed at the upper end of the mounting cylinder, a cover plate fixedly connected to the upper surface of the threaded cylinder, a sealing hole provided in the middle of the cover plate, a sliding rod slidably installed inside the sealing hole, an mounting plate fixedly connected to the upper end of the sliding rod, a threaded head provided at the lower end of the sliding rod, a damping piston threadedly installed on the outer surface of the threaded head through a threaded hole, a sealing ring fixedly connected to the outer circumferential surface of the damping piston, the sealing ring slidably connected to the inner wall surface of the mounting cylinder, a through hole provided on one side of the inside of the damping piston, an adjusting plug threadedly installed at the upper end of the inside of the through hole, an inclined hole provided on the side of the through hole, the upper opening of the inclined hole being located on the upper surface of the damping piston.

[0008] Preferably, a support spring is fixedly installed inside the positioning cylinder, and the support spring is tightly connected to the inside of the mounting cylinder.

[0009] Preferably, the support spring is located on the lower surface of the damping piston. By setting a positioning cylinder below the damping piston, the support spring can be assembled and installed. This can buffer and support the positioning, ensure the stability of damping and shock absorption during up and down sliding, and facilitate installation and use.

[0010] Preferably, a filling pipe is fixedly connected to one side of the outer surface of the mounting cylinder, and a protective head is installed on the internal thread of the filling pipe.

[0011] Preferably, the protective head has a one-way filling hole inside, which is connected to one side of the interior of the mounting cylinder.

[0012] Preferably, the filling pipe is located on the side of the mounting cylinder and at the upper end of the fixing plate. The filling pipe is connected to the mounting cylinder to install the protective head and the one-way filling hole. It can be combined and positioned to facilitate the one-way addition of hydraulic oil to form a damping medium, which is convenient for support and protection and easy to install and use.

[0013] Compared with the prior art, the present invention provides a vehicle hydraulic suspension, which has the following beneficial effects: Through its design, the hydraulic suspension uses a threaded cylinder and cover plate to be installed on the upper end of the mounting cylinder, thereby sliding the sliding rod and mounting plate. This facilitates separate installation and positioning. Furthermore, the internal installation of a damping piston, along with through holes and tilting holes, forms a damping structure for slow lifting and adjustment, thus providing shock absorption support. This design is beneficial for protecting vehicle components, ensuring safety, stability, and high adaptability. Attached Figure Description

[0016] 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.

[0017] This utility model provides a technical solution, a vehicle hydraulic suspension; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The system includes a fixed plate 1, with a mounting cylinder 11 fixedly connected to its upper surface. A threaded cylinder 12 is threadedly installed inside the upper end of the mounting cylinder 11. A cover plate 13 is fixedly connected to the upper surface of the threaded cylinder 12. A sealing hole 14 is provided in the middle of the cover plate 13. A sliding rod 15 is slidably installed inside the sealing hole 14. The sliding rod 15 can be inserted into the sealing hole 14 first, and then the threaded cylinder 12 can be threaded into the mounting cylinder 11. This facilitates separate installation and positioning, avoids interference, and has high adaptability. The upper end of the sliding rod 15... A mounting plate 16 is fixedly connected. The lower end of the sliding rod 15 is provided with a threaded head 17. A damping piston 2 is threaded onto the outer surface of the threaded head 17 through a threaded hole 18. Before installing the cover plate 13, the damping piston 2 can be connected to the threaded head 17 to position it on the sliding rod 15, facilitating installation and use. The split structure also facilitates partial replacement and maintenance. A sealing ring 21 is fixedly connected to the outer surface of the damping piston 2, and the sealing ring 21 is slidably connected to the inner wall surface of the mounting cylinder 11. The interior of the damping piston 2... A through hole 22 is provided on one side, and an adjusting plug 23 is threadedly installed at the upper end of the through hole 22. An inclined hole 24 is provided on the side of the through hole 22, and the upper opening of the inclined hole 24 is located on the upper surface of the damping piston 2. After the damping piston 2 is positioned inside the mounting cylinder 11, hydraulic oil is added to the mounting cylinder 11. It is then installed on the frame through the fixing plate 1. The upper mounting plate 16 can be used with screws to install vehicle parts, which is beneficial for buffer support and protection. When the vehicle parts vibrate, the sliding rod 15 can be pushed to slide up and down, thereby sliding the damping piston 2 inside the mounting cylinder 11. In this way, the hydraulic oil inside can enter the inclined hole 24 from the through hole 22 and enter the other side of the damping piston 2. By reducing the flow rate, the pressure can be slowly released, thereby playing a damping and shock absorption role. Before installation, the adjusting plug 23 can be manually rotated to change the installation height position and the blocking position of the inclined hole 24 port, which can also adjust the size of the flow port and thus change the magnitude of the damping force. It is easy to adjust and use as needed, and has high adaptability.

[0018] Please see Figure 2 , Figure 3 and Figure 4 A positioning cylinder 25 is fixedly connected to the lower surface of the damping piston 2. The positioning cylinder 25 is located at the lower end of the through hole 22. A support spring 26 is fixedly installed inside the positioning cylinder 25. The support spring 26 is tightly connected to the inside of the mounting cylinder 11. The support spring 26 is located on the lower surface of the damping piston 2. By setting the positioning cylinder below the damping piston, the support spring can be combined and installed. This can buffer the support and position, ensure the stability of damping and shock absorption during up and down sliding, and facilitate installation and use. By pressing the support spring 26 against the lower part of the damping piston 2, it can provide elastic support, facilitate upward pressing and reset, and also play a certain role in shock absorption. It is convenient to install and use and has high adaptability.

[0019] Please see Figure 1 , Figure 2 and Figure 5 A filling pipe 27 is fixedly connected to one side of the outer surface of the mounting cylinder 11. A protective head 28 is installed inside the filling pipe 27 with internal threads. The protective head 28 has a one-way filling hole 29 inside, which is connected to the inside of the mounting cylinder 11. The filling pipe 27 is located on the side of the mounting cylinder 11 and at the upper end of the fixing plate 1. The filling pipe is connected to the mounting cylinder, thereby installing the protective head and the one-way filling hole. It can be combined and positioned, which is conducive to the one-way addition of hydraulic oil to form a damping medium, which is convenient for support and protection, and is easy to install and use. Hydraulic oil can be added from the filling pipe 27, combined with the one-way filling hole 29 for one-way filling, avoiding leakage to the outside. It is convenient to use in combination and can replenish hydraulic oil to ensure the damping pressure inside the mounting cylinder 11. It has high adaptability and is safe and stable.
