Description

機車前避震器之活塞結構 Piston structure of locomotive front shock absorber

本創作「機車前避震器之活塞結構」,涉及一種避震器之活塞其能用以提高初速阻尼之技術領域。 The creation of the "piston structure of the locomotive front shock absorber" relates to a piston of a shock absorber which can be used to improve the technical field of initial velocity damping.

避震器在各種車輛的行進中,除了能吸收路面因為崎嶇不平所導致的震動,減少乘員不適之外,對車輛的操控效能與穩定性也有著舉足輕重的影響。通常初速行駛時需要柔軟的反應以增進舒適性;高速行駛時則需要較硬的反應以增加貼地性與穩定性。如果要同時兼顧軟硬的反應需求,有些高檔避震器甚至可以藉由切換不同的阻尼油孔,達到改變避震效果之目的。 In the travel of various vehicles, the shock absorbers can absorb the vibration caused by the rugged road surface and reduce the discomfort of the occupants, and have a significant influence on the handling efficiency and stability of the vehicle. Generally, a soft reaction is required at the initial speed to improve comfort; at high speeds, a hard reaction is required to increase the grounding and stability. If you want to take into account both soft and hard reaction requirements, some high-end shock absorbers can even change the shock absorber effect by switching different damping oil holes.

坊間所有避震器在作動被壓縮(業界稱為壓側)後,都還須要拉伸復位(業界稱為伸側),惟結構設計上要能完全迎合伸側與壓側之需求實屬不易且困難,當中存有諸多困難。就習知機車前避震器於伸側阻尼之初速效能來說,即一直存在此一缺失。 All the shock absorbers in the workshop are still required to be stretched and reset after being actuated and compressed (known as the press side in the industry). However, it is not easy to fully meet the requirements of the extension side and the pressure side in the structural design. And there are difficulties, and there are many difficulties. As far as the conventional locomotive front shock absorber is used for the initial velocity performance of the extension side damping, there is always such a deficiency.

顯見,現有避震器之結構,就伸側阻尼之初速效能而言,仍不理想完善,實有改進的必要。創作人有鑑於此,特以研創成本案,期能藉本案之提出,俾改進現有 避震器之缺點,期使避震器之功能得以更臻完善且理想,真正完全符合實際需求。 Obviously, the structure of the existing shock absorber is still not ideally perfected in terms of the initial velocity performance of the extension side damping, and it is necessary to improve.

In the present case, the "piston structure of the front shock absorber of the locomotive", inside the shock absorber 1, a piston 2 is fixed, and the piston 2 includes a main oil passage 23, one or More than one first auxiliary oil passage 221 and one or more second auxiliary oil passages 223, the first auxiliary oil passage 221 is provided with a first elastic valve body assembly 222 that can be opened and closed and reset at the bottom end of the first auxiliary oil passage 221, and the first A second elastic valve body assembly 224 is provided at the top of the second oil passage 223 for opening and closing and resetting. The two elastic valve body assemblies have different resistances; wherein the elastic force of the first elastic valve body assembly 222 is relatively small, that is, The resistance is relatively small, the opening speed is relatively fast, and the oil body flow can be provided for the pressure side. The elastic force of the second elastic valve body assembly 224 is relatively large, that is, the resistance is relatively large, and the opening speed is relatively high. Slow, it can be used to provide oil flow in general when extending the side. The first elastic valve body assembly 222 and the second elastic valve body assembly 224 both have a valve function, and the structure can be used for deformation, and the functions include opening and closing. The piston 2 includes a first body 21, and the main oil passage 23 is located in the first body 21, and the first auxiliary oil passages 221 and the second auxiliary oil passages 223 are located beside the first body 21. In the second body 22, the first auxiliary oil passages 221, the second auxiliary oil passages 223 and the main oil passages 23 are independently disposed and are not connected to each other. Preferably, each of the first auxiliary oil passages 221 and the second auxiliary oil passages 223 have a slight inclination. The shock absorber 1 includes an outer oil pipe 11 and a convex ring 13 disposed therein. A concave ring 225 is disposed on a side edge of the second body 22 of the piston 2.

The inner oil pipe 12 is internally provided with an inner space 120, and the piston 2 is located at the top of the inner oil pipe 12.

本案實施當避震器1作動且被壓縮時,如第三圖,部份油體3因受壓迫流入主油道23而通過該活塞2,其 它部份油體3則會進入該第一副油道221,此時第二副油道223被頂部第二彈性閥體組件224封閉;油體3進入該第一副油道221後將順勢推開該第一彈性閥體組件222,最後通過該活塞2。當完成上述壓側動作後,避震器1需執行伸側動作以復位,如第四圖,油體3回流,部份油體3流入主油道23而通過該活塞2,其它部份油體3則會進入該第二副油道223,此時第一副油道221被底部第一彈性閥體組件222封閉;油體3進入該第二副油道223後將順勢推開該第二彈性閥體組件224,最後通過該活塞2。 When the shock absorber 1 is actuated and compressed, as shown in the third figure, part of the oil body 3 passes through the piston 2 due to being forced to flow into the main oil passage 23, A part of the oil body 3 enters the first auxiliary oil passage 221, and the second auxiliary oil passage 223 is closed by the top second elastic valve body assembly 224; the oil body 3 enters the first auxiliary oil passage 221 and will follow the trend. The first resilient valve body assembly 222 is pushed open and finally passed through the piston 2. After the above-mentioned pressure side action is completed, the shock absorber 1 needs to perform the extension side action to reset. As shown in the fourth figure, the oil body 3 is recirculated, and part of the oil body 3 flows into the main oil passage 23 and passes through the piston 2, and other parts of the oil The body 3 will enter the second auxiliary oil passage 223. At this time, the first auxiliary oil passage 221 is closed by the bottom first elastic valve body assembly 222; after the oil body 3 enters the second auxiliary oil passage 223, the first auxiliary oil passage 3 will be pushed forward. The second resilient valve body assembly 224 finally passes through the piston 2.

由於本案設定該第一彈性閥體組件222之彈力相對較小,亦即其阻力相對較小,開啟速度相對較快,能適合於壓側時提供油體流通用;至於該第二彈性閥體組件224之彈力相對較大,亦即其阻力相對較大,開啟速度相對較慢,能適合於伸側時提供油體流通用。因此單一結構完全能迎合與滿足避震器1之壓側與伸側用,使避震提升效能,特別是提高該伸側初速阻尼,以滿足實際需求。 Since the elastic force of the first elastic valve body assembly 222 is relatively small, that is, the resistance is relatively small, the opening speed is relatively fast, and the oil body flow can be provided for the pressure side; and the second elastic valve body is provided. The elastic force of the assembly 224 is relatively large, that is, its resistance is relatively large, and the opening speed is relatively slow, which can be adapted to provide oil flow in general when the side is extended. Therefore, the single structure can fully meet and satisfy the pressure side and the extension side of the shock absorber 1, so as to improve the suspension performance, and particularly improve the initial speed damping of the extension side to meet the actual demand.
