Description

Technical Field

[0001] The invention relates to a shock absorber, in particular to a shock absorber valve system structure capable of automatically offsetting temperature influence, and a temperature adaptive shock absorber adopting the shock absorber valve system structure. Background Art

[0002] The damping valve system of the shock absorber plays a decisive role in the performance of the shock absorber. When the shock absorber is working, the piston rod performs stretching and compression movements. During the compression stroke, the hydraulic oil pushes the valve plate of the compression damping valve system to deform it, and during the recovery stroke, the hydraulic oil pushes the valve plate in the recovery damping valve system to deform it; after the valve plate is deformed, a gap is formed between it and the valve body. When the oil flows through the gap, the friction between the valve system parts and the oil and the friction within the liquid molecules form a damping force on the vibration, converting the vibration energy of the vehicle into heat energy, which is absorbed by the oil and the shock absorber housing and then dissipated into the atmosphere.

[0003] The essence of the valve system's work is to convert kinetic energy into thermal energy, which will inevitably lead to an increase in temperature. The density of the shock absorber hydraulic oil will decrease as the temperature increases, and the damping force generated by the valve system will also decrease, resulting in a deviation from the preset value, affecting the performance of the shock absorber. In addition, when the valve system is in a low-temperature environment, the density of the hydraulic oil will increase as the temperature decreases, and the damping force generated by the shock absorbing valve system will increase, which will also deviate from the preset value, affecting the performance of the shock absorber. Regarding the impact of low temperatures, there are cases in the industry where a heating component is set inside the shock absorber. In patent document CN 113309808 A, the impact of low temperatures can be eliminated by heating the shock absorber hydraulic oil to increase its temperature. However, there is no solution in the industry for the problem of reduced damping force due to high temperature and deviation from the preset value. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a damping valve system structure that automatically offsets the influence of temperature. The damping valve system structure of the present invention can automatically increase the preload force applied to the valve plate when the temperature rises, so that the force required to push the valve plate increases, compensates for the damping force, and offsets the influence of the damping force decrease caused by the increase in temperature and the decrease in the density of the hydraulic oil on the performance of the shock absorber. The damping valve system structure of the present invention can automatically reduce the damping force applied to the valve plate in a low temperature environment, so that the force required to push the valve plate is reduced, and offsets the influence of the damping force increase caused by the decrease in temperature and the increase in the density of the hydraulic oil on the performance of the shock absorber. Correspondingly, the present invention also provides a temperature-adaptive shock absorber. The temperature-adaptive shock absorber of the present invention adopts a damping valve system structure that automatically offsets the influence of temperature, so that its performance is less affected by temperature and the generated damping force is more stable.

[0005] For the valve system structure, the present invention provides the following technical solutions:

[0006] A vibration damping valve system structure that automatically offsets the influence of temperature, comprises a valve body, on which a liquid flow channel is provided; the valve body is arranged on a supporting connecting member through an assembly hole thereon, and has an axial limit relative to the supporting connecting member; a valve plate is arranged at one end of the valve body, and the valve plate will deform after the pressure in the liquid flow channel exceeds a threshold value so that the spaces on both sides of the valve body are connected through the liquid flow channel; the vibration damping valve system structure also comprises a temperature-adaptive valve plate clamping device; the temperature-adaptive valve plate clamping device comprises a base, which cooperates with the supporting connecting member through an assembly hole thereon, and has an axial limit relative to the supporting connecting member; an annular groove is provided on the base, and an annular sliding pressure block is provided in the groove; the sliding pressure block is slidably matched with the groove wall of the groove and is sealed by a sealing ring, thereby forming an adaptive pressure chamber; the adaptive pressure chamber is filled with compressed gas; the sliding pressure block abuts against the valve plate to apply a pre-tightening force to the valve plate.

[0007] Compared with the prior art, in the damping valve system structure of the present invention, the valve plate is pre-tightened by a temperature-adaptive valve plate clamping device. When the temperature rises, the air pressure in the adaptive pressure chamber also increases, thereby increasing the pre-tightening force applied by the sliding pressure block to the valve plate, and then increasing the force required to push the valve plate, thereby compensating for the damping force and offsetting the effect of the damping force decrease on the performance of the shock absorber due to the increase in temperature and the decrease in the density of the hydraulic oil. When the damping valve system structure of the present invention is in a low temperature environment, the temperature drop will cause the air pressure in the adaptive pressure chamber to drop, thereby reducing the pre-tightening force applied by the sliding pressure block to the valve plate, and then reducing the force required to push the valve plate, thereby offsetting the effect of the damping force increase on the performance of the shock absorber due to the decrease in temperature and the increase in the density of the hydraulic oil.

[0008] Furthermore, in the aforementioned damping valve system structure that automatically offsets the influence of temperature, the sliding block is in a stepped shape, and the top of the groove is provided with a flange for limiting the sliding block. By providing the flange, the sliding block is limited in the groove and will not be separated from the base, which is beneficial to the assembly and later maintenance of the valve system.

[0009] Furthermore, the manufacturing process of the temperature-adaptive valve plate clamping device includes the following steps:

[0010] S1, manufacturing a base blank without flanges;

[0011] S2, manufacturing a sliding block and putting on a sealing ring;

[0012] S3, inserting the sliding pressing block into the groove on the base blank, and then processing the flange;

[0013] S4, filling gas into the adaptive pressure chamber.

[0014] The temperature-adaptive valve plate pressing device is manufactured according to the above steps, with reasonable process and easy implementation.

[0015] Furthermore, in step S3, a rotary riveting process may be used to form the flange.

[0016] Furthermore, a gas port is provided at the end of the base blank, and a gas-filled rivet is provided on the gas port, so that gas can be filled into the adaptive pressure chamber through the gas-filled rivet, which is easy to implement and has high product reliability.

[0017] Furthermore, in step S4, the sliding block is first adjusted to abut against the bottom of the groove to discharge air, and then the inflatable rivet is installed, and then the inert gas is filled in. Thus, after the inflation is completed, the adaptive pressure chamber is filled with inert gas, which can prevent the oxygen and moisture in the air from corroding the relevant components.

[0018] For the shock absorber, the present invention provides the following technical solutions:

[0019] The temperature adaptive shock absorber comprises a piston valve assembly; the piston valve assembly comprises a shock absorber connecting rod and a piston valve fixedly arranged at the lower end of the shock absorber connecting rod; the piston valve comprises a piston valve body, the middle part of the piston valve body has an assembly hole, and the piston valve body cooperates with the lower end of the shock absorber connecting rod through the assembly hole thereon; a compression damping valve plate and a temperature adaptive compression valve plate clamping device are sequentially arranged on the upper side of the piston valve body to form a compression stroke shock absorber valve system; a recovery damping valve plate and a temperature adaptive recovery valve plate clamping device are sequentially arranged on the lower side of the piston valve body to form a recovery stroke shock absorber valve system; in the compression stroke shock absorber valve system: the temperature adaptive compression valve plate clamping device comprises a compression damping base, the compression damping base cooperates with the shock absorber connecting rod through the assembly hole thereon, and abuts against the step surface on the shock absorber connecting rod to form an axial limit; an annular groove is arranged on the compression damping base, and an annular compression damping sliding pressure block is arranged in the groove; the compression damping The sliding pressure block of the damper slides with the groove wall of the groove and is sealed by a sealing ring, thereby forming a compression damping adaptive pressure chamber; the compression damping adaptive pressure chamber is filled with compressed gas; the compression damping sliding pressure block abuts against the compression damping valve plate located on the lower side thereof, and applies a pre-tightening force to the compression damping valve plate; in the recovery stroke damping valve system: the temperature adaptive recovery valve plate clamping device includes a recovery damping base, the recovery damping base cooperates with the shock absorber connecting rod through the threaded hole thereon, and axial fastening is achieved by a threaded connection structure; the recovery damping base is provided with an annular groove, and an annular recovery damping sliding pressure block is provided in the groove; the recovery damping sliding pressure block slides with the groove wall of the groove and is sealed by a sealing ring, thereby forming a recovery damping adaptive pressure chamber; the recovery damping adaptive pressure chamber is filled with compressed gas; the recovery damping sliding pressure block abuts against the recovery damping valve plate located on the upper side thereof, and applies a pre-tightening force to the recovery damping valve plate.

[0020] Compared with the prior art, in the temperature adaptive shock absorber of the present invention, both the compression stroke shock absorber valve system and the recovery stroke shock absorber valve system adopt a shock absorber valve system structure that automatically offsets the influence of temperature. When the temperature rises, the preload force applied to the valve plate can be automatically increased, and when the temperature drops, the preload force applied to the valve plate can be automatically reduced, thereby offsetting the influence of temperature increase or reduction on the damping force, so that the performance of the shock absorber is stable.

[0021] Furthermore, an upper gasket is provided between the compression damping base and the compression damping valve plate; a lower gasket is provided between the restoration damping base and the restoration damping valve plate.

[0033] The technical solution of the present invention is further described in detail below through specific embodiments, but it is not used as a basis for limiting the present invention. The contents not described in detail below or the structures not shown in the drawings are all common technical knowledge in the art.

[0034] It should be noted that, in the technical solution of the present invention, "upper" and "lower" are described according to the orientation relationship in the actual use state, while the structure shown in the accompanying drawings is arranged horizontally according to the drawing habits of technicians.

[0035] See also Figure 1 The vibration damping valve system structure for automatically offsetting the temperature influence of the present invention comprises a valve body 1, on which a liquid flow channel is provided; the valve body 1 is arranged on a supporting connecting member through an assembly hole thereon, and has an axial limit relative to the supporting connecting member; a valve plate 2 is arranged at one end of the valve body 1, and the valve plate 2 will deform after the pressure in the liquid flow channel exceeds a threshold value so that the spaces on both sides of the valve body are connected through the liquid flow channel; the above is a common design in this field. Different from the prior art, the vibration damping valve system structure of the present invention also includes a temperature-adaptive valve plate clamping device; the temperature-adaptive valve plate clamping device includes a base 3, which cooperates with the supporting connecting member through an assembly hole thereon, and has an axial limit relative to the supporting connecting member; an annular groove is provided on the base 3, and an annular sliding pressure block 4 is provided in the groove; the sliding pressure block 4 slides with the groove wall of the groove and is sealed by a sealing ring, thereby forming an adaptive pressure chamber 6; the adaptive pressure chamber 6 is filled with compressed gas; the sliding pressure block 4 abuts against the valve plate 2 to apply a pre-tightening force to the valve plate 2.

[0036] When the damping valve system structure of the present invention is in a high temperature environment, the air pressure in the adaptive pressure chamber 6 will rise due to the thermal expansion effect, thereby increasing the preload force applied to the valve plate 2, so that the force required to push the valve plate 2 is increased, offsetting the effect of the damping force being reduced due to the increase in temperature and the decrease in the density of the shock absorber hydraulic oil. When the damping valve system structure of the present invention is in a low temperature environment, the air pressure in the adaptive pressure chamber 6 will drop due to the cold contraction effect, thereby reducing the preload force applied to the valve plate 2, so that the force required to push the valve plate 2 is reduced, offsetting the effect of the damping force being increased due to the decrease in temperature and the increase in the density of the shock absorber hydraulic oil.

[0037] In some specific embodiments of the present invention, the sliding block 4 is stepped, and the top of the groove is provided with a flange 301 for limiting the sliding block 4. The flange 301 limits the sliding block 4, so that the sliding block 4 is always located in the groove, which is conducive to the assembly of the valve system.

[0039] S1, manufacturing a base blank without flange 301;

[0040] S2, manufacturing a sliding pressing block 4 and putting a sealing ring on it;

[0041] S3, insert the sliding pressing block 4 into the groove on the base blank, and then process the flange 301;

[0042] S4, filling gas into the adaptive pressure chamber 6.

[0043] Furthermore, in step S3, the flange 301 may be processed by a rotary riveting process.

[0044] In some specific embodiments of the present invention, the end of the base blank is provided with an air port, and the air port is provided with an inflatable rivet 5. Thus, compressed gas can be charged into the adaptive pressure chamber 6 through the inflatable rivet 5, which is easy to implement and has the advantage of not damaging the sealing ring compared to the method of inserting a needle from the sealing ring position for inflating.

[0045] Furthermore, in step S4, the sliding block 4 can be adjusted to abut against the bottom of the groove to discharge air, and then the inflatable rivet 5 is installed, and then the inert gas is filled in. Thus, before the inert gas is filled in, the air is discharged, and after the inert gas is filled in, the adaptive pressure chamber 6 is filled with inert gas.
