氣體輔助的液壓阻尼器Gas-assisted hydraulic damper

本創作涉及液壓減震器技術領域，尤其涉及一種氣體輔助的液壓阻尼器。The present invention relates to the field of hydraulic shock absorber technology, and more particularly to a gas assisted hydraulic damper.

液壓阻尼器，又叫粘滯阻尼器，液壓減震器，根據流體運動，特別是當流體通過節流孔時會產生粘滯阻力的原理而製成的，是一種與剛度、速度相關型阻尼器。廣泛應用於高層建築、橋樑、建築結構抗震改造、工業管道設備抗振、軍工等領域。Hydraulic dampers, also known as viscous dampers, hydraulic dampers, are based on the principle of fluid motion, especially when the fluid passes through the orifice, resulting in a viscous, speed-dependent damping. Device. Widely used in high-rise buildings, bridges, seismic structures of building structures, anti-vibration of industrial pipeline equipment, military and other fields.

傳統的結構抗震是通過增強結構本身的抗震性能（強度、剛度、延性）來抵禦地震、風、雪、海嘯等自然災害的。由於自然災害作用強度和特性的不確定性，傳統的抗震方法設計的結構又不具備自我調節能力，應用於汽車防碰撞結構又吞噬掉汽車前部空間，這無疑需懸掛系統變得更為緊湊。對於空間相對較小的車特別是轎車來說，問題顯得更為突出，因此適用範圍受到很大的限制。The traditional structural earthquake resistance is to resist the natural disasters such as earthquakes, wind, snow and tsunami by enhancing the seismic performance (strength, stiffness and ductility) of the structure itself. Due to the uncertainty of the strength and characteristics of natural disasters, the traditional seismic design method does not have self-adjusting ability. It is applied to the anti-collision structure of the car and engulfs the front space of the car. This undoubtedly requires the suspension system to become more compact. . For cars with relatively small spaces, especially cars, the problem is more prominent, so the scope of application is greatly limited.

現有的液壓減震器結構分為兩類:一類為液壓減震器和空氣彈性件分開佈置。另一類為液壓減震器與螺旋彈性件結合在一起的結構。這類減震器由於彈性件剛度不可變或可變範圍有限，因此適應範圍較小，在空氣彈性件發生足夠形變之前具有不穩定性。The existing hydraulic shock absorber structures are divided into two categories: one is a hydraulic shock absorber and the air elastic member is separately arranged. The other type is a structure in which a hydraulic shock absorber is combined with a spiral elastic member. Such shock absorbers have a small adaptation range due to the non-variable stiffness or limited range of the elastic members, and are unstable before the air elastic members are sufficiently deformed.

綜上可知，現有液壓減震器在實際使用上，體積大不符合輕便靈活適應抗震的要求，顯然存在不便與缺陷，所以有必要加以改進。In summary, the existing hydraulic shock absorbers in actual use, large size does not meet the requirements of light and flexible to adapt to earthquake resistance, obviously inconvenience and defects, so it is necessary to improve.

結合圖2A所示，固定閥300的另一端設置有凸柱311，穿設活動閥200，凸柱311頂端設置有大於圓環孔211的限位結構312，更優選的，固定閥300和限位結構312為圓柱體，活動閥200為圓環體，活動閥200的圓環孔211的直徑大於凸柱311的直徑並小於所述限位結構312的直徑，活動閥200通過圓環孔211穿設在凸柱311上。As shown in FIG. 2A, the other end of the fixed valve 300 is provided with a stud 311, and the movable valve 200 is disposed. The top end of the stud 311 is provided with a limiting structure 312 larger than the annular hole 211. More preferably, the fixed valve 300 and the limit are fixed. The movable structure 200 is a circular body, and the movable valve 200 is a circular ring.

It is worn on the stud 311.

使活動閥200套在固定閥300的凸柱311上面，可關閉和打開排流孔321，保持分離時，設置在固定閥300的排流孔321可流過工作液體，固定閥300與活動閥200外徑不同，兩者略小於缸體100的內徑，固定閥300另一端設有液壓連動杆301，液壓連動杆301設有與缸體100緊密貼合的密封圈400，中間件500，如圖2B、2D，密封圈400設置有中間件固定孔421與中間件的固定元件521的形狀密合，可以是圓臺形，中間件500設有固定彈簧600的結構--穿孔501，當缸體蓋700與缸體100組裝後，空氣密閉於氣體容置空間172內。本實施例中將各零部件組合後，如圖3所示。The movable valve 200 is placed on the boss 311 of the fixed valve 300 to close and open the drain hole 321 . When the separation is maintained, the drain hole 321 disposed in the fixed valve 300 can flow through the working fluid, and the fixed valve 300 and the movable valve The outer diameter of the 200 is different, and the two are slightly smaller than the inner diameter of the cylinder 100. The other end of the fixed valve 300 is provided with a hydraulic linkage rod 301. The hydraulic linkage rod 301 is provided with a sealing ring 400 closely attached to the cylinder 100, and the intermediate member 500. 2B, 2D, the sealing ring 400 is provided with the intermediate member fixing hole 421 and the shape of the fixing member 521 of the intermediate member, which may be a truncated cone shape, and the intermediate member 500 is provided with a structure of the fixing spring 600 - the through hole 501, when After the cylinder cover 700 is assembled with the cylinder 100, the air is sealed in the gas accommodation space 172. After combining the components in this embodiment, as shown in FIG.

所述固定閥300上設有至少一個節流管道322，當固定閥300與活動閥200相密合或者分離時，節流管道322均處於打開狀態。固定閥300上與活動閥200相密合時的接觸面為第一接觸面，活動閥200上與固定閥300相密合時的接觸面為第二接觸面，所述第一接觸面大於所述第二接觸面，節流管道322設於所述第一接觸面上且超出所述第二接觸面的位置，工作液體從此空隙中可以流過，見圖5。排流孔321設於第一接觸面上且與所述第二接觸面交集的位置，固定閥300與活動閥200的關閉排流孔321時，防止工作液體從排流孔321通過。中心對稱的均勻分佈的排流孔321使得工作液體流過排流孔321時，不會產生扭力帶動液壓連動杆301打轉，增加穩定性，減少磨損。The fixed valve 300 is provided with at least one throttle pipe 322. When the fixed valve 300 is in close contact with or separated from the movable valve 200, the throttle pipe 322 is in an open state. The contact surface when the fixed valve 300 is in close contact with the movable valve 200 is the first contact surface, and the contact surface when the movable valve 200 is in close contact with the fixed valve 300 is the second contact surface, and the first contact surface is larger than the The second contact surface is disposed on the first contact surface and beyond the position of the second contact surface, and the working liquid can flow through the gap, as shown in FIG. When the drain hole 321 is provided on the first contact surface and intersects with the second contact surface, when the fixed valve 300 and the movable valve 200 close the drain hole 321, the working liquid is prevented from passing through the drain hole 321. The centrally symmetric uniformly distributed drainage holes 321 prevent the hydraulic fluid linkage rod 301 from rotating when the working fluid flows through the drainage holes 321 to increase stability and reduce wear.

如圖4所示，當液壓連動杆301受力推入缸體100內，此時固定閥300與活動閥200相密合，進而關閉排流孔321，工作液體經由節流管道322通過，因而達到液壓阻尼緩衝的效果；同時液壓連動杆301進入液體容置空間162內，液壓連動杆301增加的體積使液體容置空間162變大，使液體容置空間162內的工作液體因而推動密封圈400，繼而推動中間件500，繼而又推動彈簧600，使彈簧600收縮，此時氣體容置空間172變小，空氣經由氣孔711，排出氣體容置空間172。As shown in FIG. 4, when the hydraulic linkage rod 301 is forced into the cylinder 100, the fixed valve 300 is in close contact with the movable valve 200, thereby closing the drainage hole 321, and the working liquid passes through the throttle conduit 322. The effect of the hydraulic damping buffer is achieved; at the same time, the hydraulic linkage rod 301 enters the liquid accommodating space 162, and the increased volume of the hydraulic linkage rod 301 enlarges the liquid accommodating space 162, so that the working liquid in the liquid accommodating space 162 pushes the sealing ring. 400, which in turn pushes the intermediate member 500, and then pushes the spring 600 to contract the spring 600. At this time, the gas accommodating space 172 becomes small, and the air is discharged through the air hole 711 to the gas accommodating space 172.

如圖5所示，排流孔321關閉狀態下，隨著液壓連動杆301進一步擠壓工作液體，工作液體擠壓氣體容置空間172，氣體容置空間172內部壓強增加，開始輸出彈力，彈簧600處於壓縮狀態，彈簧600的伸展力作用在中間件500和密封圈400上輸出支撐力，當氣體容置空間172關閉至一定位置時，彈簧600又起到增強緩衝的作用，氣體容置空間172可以緩慢的閉合。As shown in FIG. 5, in the closed state of the drain hole 321 , as the hydraulic linkage rod 301 further squeezes the working liquid, the working liquid presses the gas accommodation space 172, and the internal pressure of the gas accommodation space 172 increases, and the output spring force starts to be output. The 600 is in a compressed state, and the extension force of the spring 600 acts on the intermediate member 500 and the sealing ring 400 to output a supporting force. When the gas accommodating space 172 is closed to a certain position, the spring 600 functions to enhance the buffering, and the gas accommodating space is provided. 172 can be closed slowly.

如圖6、圖7所示，當液壓連動杆301受力拉出缸體100外，此時固定閥300與活動閥200相分離，進而打開排流孔321，工作液體同時經由排流孔321通過以及節流管道322通過，因而沒有產生液壓阻尼緩衝的效果，可以輕易的拉出；同時液壓連動杆301退出液體容置空間162外，液壓連動杆301減少的體積使液體容置空間162減小，使氣體容置空間172內的彈簧600因而舒張推動中間件500，繼而又推動密封圈400，此時氣體容置空間172變大，空氣，經由氣孔711，進入氣體容置空間172。As shown in FIG. 6 and FIG. 7 , when the hydraulic linkage rod 301 is pulled out of the cylinder 100 by force, the fixed valve 300 is separated from the movable valve 200 at this time, thereby opening the drainage hole 321 , and the working liquid is simultaneously discharged through the drainage hole 321 . Through the passage of the throttle pipe 322, the hydraulic damping buffer is not generated, and the hydraulic damping rod 301 can be easily pulled out; while the hydraulic linkage rod 301 is out of the liquid accommodating space 162, the reduced volume of the hydraulic linkage rod 301 reduces the liquid accommodating space 162. Small, the spring 600 in the gas accommodating space 172 thus relaxes and pushes the intermediate member 500, and then pushes the sealing ring 400. At this time, the gas accommodating space 172 becomes large, and the air enters the gas accommodating space 172 via the air hole 711.

如圖2C所示，缸體蓋700的頂端設置有氣孔711，用於進氣或排氣。更進一步地，在缸體蓋700的外徑邊緣處設置氣孔711，可根據需要對氣體容置空間172設置氣壓閾值的上限和下限，內部達到所述閾值上限時氣孔711開始排氣，設置氣壓低於所述氣壓閾值的下限，氣孔711開始進氣，可隨著固定閥300的運動改變氣體容置空間172的容積，改變內部氣壓的大小。As shown in Fig. 2C, the top end of the cylinder cover 700 is provided with a vent 711 for intake or exhaust. Further, a gas hole 711 is provided at the outer diameter edge of the cylinder cover 700, and an upper limit and a lower limit of the gas pressure threshold may be set to the gas accommodation space 172 as needed, and when the internal upper limit is reached, the air hole 711 starts to exhaust, and the air pressure is set.
