Description

Technical Field

[0001] This utility model specifically relates to a quick-release air spring anti-rotation structure. Background Technology

[0002] As people demand higher levels of vehicle comfort, more passenger cars are equipped with multi-chamber air springs. At the same time, the load and torsional angle of the air springs are increasing, which places more stringent demands on the anti-rotation function of the air springs, because there is relative rotation between the air springs and the shock absorbers due to the motion.

[0003] Existing anti-rotation structures such as Figure 4 As shown, the shape and structure are relatively complex, with many parts, making assembly difficult. Furthermore, the anti-rotation structure has the risk of relative rotation due to insufficient supporting friction torque to overcome the torsional tendency, resulting in rotational wear and noise, which affects the performance. Therefore, we propose a quick-replacement air spring anti-rotation structure. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release air spring anti-rotation structure to solve the problems mentioned in the background art.

[0006] A vibration damper, wherein a positioning element is sleeved on the outside of the vibration damper, and the top of the positioning element has a sealing ring;

[0007] A piston, one end of which is fitted onto the outer wall of the positioning member;

[0008] The piston sidewall has a threaded hole at its lower end, and a locking screw that mates with a positioning component is connected to the inner side of the threaded hole via a threaded portion.

[0009] Preferably, the positioning element is a positioning ring, and one end of the locking screw abuts against the positioning ring.

[0010] Preferably, the positioning element is a spring seat with a tapered cross-section and a groove on the outer wall of the spring seat, and the locking screw engages with the spring seat through the groove.

[0011] Preferably, the locking screw includes a threaded rod, a screw head, and a protrusion. The screw head is fixed on the threaded rod, and the upper surface of the screw head has a protrusion with a "D" shaped cross-section.

[0012] Preferably, the protrusion has an internal six-hole.

[0013] Preferably, the cross-section of the screw head is trapezoidal, and the threaded rod, screw head, and protrusion are integrally formed.

[0014] Preferably, the locking screw is made of stainless steel or titanium alloy.

[0015] Preferably, multiple locking screws are evenly distributed along the circumference of the positioning ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model uses threaded holes and locking screws to facilitate the anti-rotation function of the air spring, avoiding the insufficient friction of traditional methods that cause relative rotational wear and excessive noise between the air spring and the shock absorber. This structure is simple, easy to install, and highly reliable. In practical applications, the number of locking screws can be adjusted according to the torsion angle of the air spring to improve the practicality of the device. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model provides a technical solution: a quick-release air spring anti-rotation structure, comprising:

[0026] Vibration damper 1, with a positioning component sleeved on the outside of the vibration damper 1, and a sealing ring 3 at the top of the positioning component;

[0027] Piston 4, one end of which is fitted onto the outer wall of the positioning component;

[0028] Among them, the lower end of the side wall of the piston 4 is provided with a threaded hole 5, and the inner side of the threaded hole 5 is connected with a locking screw 6 that cooperates with the positioning part through the threaded part.

[0029] The threaded part allows for a tight clamping force between the locking screw 6 and the positioning element, thus preventing rotation. In actual operation, the anti-rotation effect can be adjusted according to the torsion angle of the air spring.

[0030] In this embodiment, preferably, the positioning element is a positioning ring 2, and one end of the locking screw 6 abuts against the positioning ring 2;

[0031] It facilitates a greater clamping and locking effect through threaded feeding, reducing the rotation of piston 4.

[0032] In this embodiment, preferably, the locking screw 6 includes a threaded rod 61, a screw head 62, and a protrusion 63. The screw head 62 is fixed on the threaded rod 61, and the upper surface of the screw head 62 has a protrusion 63 with a "D" shaped cross-section.

[0033] The "D"-shaped protrusion 63 facilitates smoothing of the upper surface edge of the screw head 62, preventing the screw head 62 from being too sharp and causing accidental scratches to surrounding objects after installation or fixing. It also increases the thickness of the screw head 62 to allow for deeper internal hex holes.

[0034] In this embodiment, preferably, the protrusion 63 has an internal six-hole;

[0035] The locking screw 6 is easy to screw in or out.

[0036] In this embodiment, preferably, the cross-section of the screw head 62 is trapezoidal, and the threaded rod 61, the screw head 62 and the protrusion 63 are integrally formed structures;

[0037] To facilitate better connection strength.

[0038] In this embodiment, preferably, the locking screw 6 is made of stainless steel or titanium alloy;

[0039] This facilitates better strength and corrosion resistance.

[0040] In this embodiment, preferably, multiple locking screws 6 are evenly distributed around the circumference of the positioning ring 2;

[0041] It allows for easy adjustment of the locking effect according to actual needs.

[0042] Example 1 Usage Procedure: By drilling a threaded hole 5 on the side wall of the piston 4, and then screwing the locking screw 6 into the inside of the threaded hole 5, the locking screw 6 and the positioning ring 2 form an interference fit, thereby tightly holding the shock absorber 1 and achieving the purpose of stopping rotation.

[0043] Example 2 is the same as Example 1, except that:

[0044] The positioning component is a spring seat 7, which has a tapered cross-section and a groove on its outer wall. The locking screw 6 engages with the spring seat 7 through the groove.

[0045] This facilitates better reduction of rotation between piston 4 and vibrator, ensuring a stable anti-rotation effect.

[0046] Example 2 Usage: This example does not require existing... Figure 4 The retaining ring gasket shown only requires drilling a threaded hole 5 on the piston 4, and then screwing the locking screw 6 into contact with the conical surface of the spring seat 7. The conical surface of the spring seat 7 and the conical surface of the piston 4 cooperate to bear the axial force of the air spring. The locking screw 6 is threadedly connected to the piston 4, and the end face of the locking screw 6 abuts against the conical surface of the spring seat 7. The friction of the contact end faces achieves the purpose of preventing rotation, so that the piston 4 and the spring seat 7 do not slide relative to each other in the circumference. A groove can also be provided on the conical surface of the spring seat 7, and the locking screw 6 can be directly screwed into the groove to achieve the anti-rotation effect. The number of locking screws 6 can be increased or decreased according to the actual torsion angle of the air spring, so as to quickly and conveniently adjust in practice to meet the actual needs.

[0047] This invention can effectively achieve the anti-rotation function and avoid noise caused by insufficient supporting friction torque. Compared with the traditional anti-rotation structure, it has a simple shape and structure, fewer parts, quick and convenient installation, and high reliability. It is conducive to the early-stage rapid adjustment solution of the air spring and is also easy to mass-produce. When using it, the number of screws can be increased or decreased according to the actual torsion angle of the air spring to achieve quick and convenient practical adjustment.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
