本发明涉及液压式汽车减振器领域，尤其涉及一种单涡轮回收能量的串串联R式汽车减振器与方法。The invention relates to the field of hydraulic automobile dampers, in particular to a series-series R-type automobile damper and method for recovering energy by a single turbine.
背景技术Background technique
汽车的减振方式主要有液压式、气压式、电磁式。液压式是目前用得最广泛的汽车减振方式。液压式减振器中的液压油在振荡过程中需要产生阻尼，而产生阻尼的过程是一个需要消耗能量的过程。我们将该振荡过程消耗掉的能量称为振荡耗能。目前，液压式减振器的振荡耗能是浪费掉的能量，其原因是液压减振器中没有振荡耗能回收装置。The vibration reduction methods of automobiles mainly include hydraulic type, pneumatic type and electromagnetic type. Hydraulic is the most widely used method of vibration reduction in automobiles. The hydraulic oil in the hydraulic damper needs to generate damping during the oscillation process, and the process of generating the damping is a process that requires energy consumption. The energy consumed by this oscillation process is called the oscillation energy. At present, the oscillating energy consumption of the hydraulic damper is wasted energy, because there is no oscillating energy recovery device in the hydraulic damper.

These 4-way capillaries are all M-shaped. The four capillary tubes are respectively capillary R8, R4, R2, and R1; their cross-sectional areas are equal and the solenoid valves V R8 , V R4 , V R2 , and V R1 are respectively connected in parallel. The ratio of the lengths of the four capillary tubes is 8:4:2:1; that is, their lengths are arranged according to the binary encoding rule of 8421. The damping can be adjusted by adjusting the configuration S Rn of the solenoid valves V R8 , V R4 , V R2 , V R1 .
调频段由串联的4路毛细管、电磁阀组成。这4路毛细管都盘成了M型。这4路毛细管分别是毛细管m8、m4、m2、m1；它们的截面积相等且分别并联电磁阀V m8、V m4、V m2、V m1。这4路毛细管的长度之比是8:4:2:1；即它们的长度是按照8421的二进制编码规则来排列的。这四路毛细管的直径d m大于调阻段的毛细管直径d R一倍以上。调节电磁阀V m8、V m4、V m2、V m1的组态S mn即可调节系统固有频率。 The tuning frequency band consists of a series of 4-way capillary and solenoid valves. These 4-way capillaries are all M-shaped. The four capillary tubes are capillary tubes m8, m4, m2, and m1, respectively; their cross-sectional areas are equal and the solenoid valves V m8 , V m4 , V m2 , and V m1 are respectively connected in parallel. The ratio of the lengths of the four capillary tubes is 8:4:2:1; that is, their lengths are arranged according to the binary encoding rule of 8421. The diameter d m of the four-way capillary is more than twice the capillary diameter d R of the regulation section. The natural frequency of the system can be adjusted by adjusting the configuration S mn of the solenoid valves V m8 , V m4 , V m2 , V m1 .

具体实施方式Detailed ways
下面结合具体实施例对本发明作进一步具体详细描述。The present invention will be further described in detail below in conjunction with specific embodiments.
实施例Example
如附图2所示。As shown in Figure 2.
调阻段包括四路毛细管分别是R8、R4、R2、R1；它们截面积相等且分别并联电磁阀V R8、V R4、V R2、V R1控制其工作。这四路毛细管的长度之比是8:4:2:1；它们的直径均为d R。 The regulating section includes four capillary tubes which are respectively R8, R4, R2 and R1; their cross-sectional areas are equal and the parallel solenoid valves V R8 , V R4 , V R2 , V R1 respectively control their operation. The ratio of the lengths of the four capillary tubes is 8:4:2:1; their diameters are both d R .
调频段包括四路毛细管分别是m8、m4、m2、m1；它们截面积相等且分别并联电磁阀V m8、V m4、V m2、V m1控制其工作；这四路毛细管的长度之比是8:4:2:1。在本实施例中，这四路毛细管中最短毛细管m1的长度L m1等于调阻段最长毛细管R8的长度L R8的一半。这四路毛细管的直径d m等于4倍d R。 The tuning frequency band includes four capillary tubes respectively m8, m4, m2, m1; their cross-sectional areas are equal and the parallel solenoid valves V m8 , V m4 , V m2 , V m1 respectively control their operation; the ratio of the length of the four capillary tubes is 8 :4:2:1. In the present embodiment, the length L m1 of the shortest capillary m1 of the four-way capillary is equal to half the length L R8 of the longest capillary R8 of the modulating section. The diameter d m of the four-way capillary is equal to 4 times d R .
单涡轮能量回收段包括单向阀V 3、单向阀V 4、单向阀V 5、单向阀V 6、涡轮T、发电机G。涡轮T的最大流量Q Tmax比减振器最大液压油流量Q Smax大10％；即：Q Tmax＝1.1Q Smax。 The single turbine energy recovery section includes a check valve V 3 , a check valve V 4 , a check valve V 5 , a check valve V 6 , a turbine T, and a generator G. The maximum flow rate Q Tmax of the turbine T is 10% greater than the maximum hydraulic oil flow rate Q Smax of the damper; namely: Q Tmax =1.1Q Smax .
当车架和车轴之间产生相对运动时，活塞会相应的产生或上或下的移动；活塞向上移动行程为伸张行程，活塞向下移动的行程为压缩行程。此时液压缸3内的液压油会经过A油口、B油口之间的调阻段、调频段、单涡轮能量回收段，进而从上油仓4流向下油仓6，或者从下油仓6流向上油仓4。When the relative movement between the frame and the axle occurs, the piston will correspondingly move up or down; the upward movement of the piston is the extension stroke, and the downward movement of the piston is the compression stroke. At this time, the hydraulic oil in the hydraulic cylinder 3 will pass through the adjustment section between the A port and the B port, the frequency modulation band, the single turbine energy recovery section, and then flow from the upper oil tank 4 to the oil tank 6 or from the oil. The bin 6 flows up to the oil bunker 4.
由于缸体内液压油的粘性作用，当液压油流经调阻段时，调阻段中工作的毛细管会对液压油的流动产生阻尼，从而形成对活塞移动的阻尼；该阻尼的大小由控制系统通过电磁阀的组态S Rn控制，进而实现调阻段的调阻； Due to the viscous action of the hydraulic oil in the cylinder, when the hydraulic oil flows through the adjustment section, the capillary working in the adjustment section will dampen the flow of the hydraulic oil, thereby forming a damping of the movement of the piston; the magnitude of the damping is controlled by The system is controlled by the configuration of the solenoid valve S Rn , thereby realizing the adjustment of the adjustment section;
当液压油流经调频段时，通过控制系统改变电磁阀的组态S mn，则可调节减振器的系统固有频率，进而实现调频段的调频； When the hydraulic oil flows through the frequency modulation band, the configuration S mn of the electromagnetic valve is changed by the control system, and the natural frequency of the system of the damper can be adjusted, thereby realizing the frequency modulation of the frequency modulation band;
当液压油经过单涡轮能量回收段时，根据液压油的流向，或者液压油从M三通管经过单向阀V 3、涡轮T、单向阀V 4流向下油仓6，同时涡轮T拖动发电机G发电，实现伸张行程的振荡耗能回收；或者液压油从下油仓6经过单向阀V 5、涡轮T、单向阀V 6流向M三通管，同时涡轮T拖动发电机G发电，实现压缩行程的振荡耗能回收；这样我们就解决了振荡耗能无法回收的问题。 When the hydraulic oil passes through the single turbine energy recovery section, according to the flow direction of the hydraulic oil, or the hydraulic oil flows from the M tee through the check valve V 3 , the turbine T, the check valve V 4 to the lower oil tank 6 while the turbine T is towed The generator G generates electricity to realize the oscillation energy recovery of the extension stroke; or the hydraulic oil flows from the lower oil tank 6 through the check valve V 5 , the turbine T, the check valve V 6 to the M three-way pipe, and the turbine T drags the power generation. The machine G generates electricity and realizes the recovery of the oscillation energy consumption of the compression stroke; thus, we solve the problem that the oscillation energy cannot be recovered.
现通过以下三点对本实施例作进一步说明。The present embodiment will be further described by the following three points.
1、关于单涡轮能量回收段的工作原理1. Working principle of single turbine energy recovery section
当液压油需要从M三通管流向N三通管时，活塞向上移动，此行程为伸张行程，因为单向阀V 5、V 6的截止作用，液压油只能够从M三通管经过单向阀V 3、涡轮T、单向阀V 4流向下油仓6；同时液压油推动涡轮T的叶轮转动，涡轮T拖动发电机G发电，实现伸张行程的振荡耗能回收。 When the hydraulic oil needs to flow from the M tee to the N tee, the piston moves upwards. This stroke is the extension stroke. Because of the cut-off action of the check valves V 5 and V 6 , the hydraulic oil can only pass through the M tee. The valve V 3 , the turbine T and the check valve V 4 flow to the lower oil tank 6; at the same time, the hydraulic oil pushes the impeller of the turbine T to rotate, and the turbine T drives the generator G to generate electricity, thereby realizing the recovery energy consumption of the extension stroke.
当液压油需要从N三通管流向M三通管时，活塞向下移动，此行程为压缩行程，因为单向阀V 3、V 4的截止作用，液压油只能够从N三通管经过单向阀V 5、涡轮T、单向阀V 6流向M三通管；同时液压油推动涡轮T的叶轮转动，涡轮T拖动发电机G发电，实现压缩行程的振荡耗能回收。 When the hydraulic oil needs to flow from the N-way to the M-way, the piston moves downward. This stroke is the compression stroke. Because of the cut-off action of the check valves V 3 and V 4 , the hydraulic oil can only pass through the N-way. The one-way valve V 5 , the turbine T and the one-way valve V 6 flow to the M three-way pipe; at the same time, the hydraulic oil pushes the impeller of the turbine T to rotate, and the turbine T drives the generator G to generate electricity, thereby realizing the recovery of the oscillation energy consumption of the compression stroke.
2、关于调阻段、调频段、单涡轮能量回收段的连接顺序2. Connection sequence of the regulation section, the modulation frequency band, and the single turbine energy recovery section
调阻段、调频段、单涡轮能量回收段的连接顺序除了按照如图2的顺序连接外，还可以按照调频段、单涡轮能量回收段、调阻段连接，当然，也可以按照单涡轮能量回收段、调阻段、调频段等顺序连接。The connection sequence of the regulation section, the modulation frequency band, and the single-turbine energy recovery section can be connected according to the frequency modulation band, the single-turbine energy recovery section, and the adjustment section, in addition to the sequence as shown in FIG. 2, and of course, the single-turbine energy can also be used. The recycling section, the adjustment section, the tuning frequency band, and the like are sequentially connected.
3、关于“单涡轮回收能量的串串联R式汽车减振器”的名称3. Name of “series series R type automobile damper for single turbine recovery energy”
在“单涡轮回收能量的串串联R式汽车减振器”的名称中，其“串串联”中第一个“串”表示调阻段用串联式毛细管调节、第二个“串”表示调频段用串联式毛细管调节。其“R式”表示的意义如下：In the name of "single-turbo-recovery energy series-series R-type automobile damper", the first "string" in the "string series" indicates that the tuning section is adjusted by series capillary, and the second "string" indicates frequency modulation. The section is adjusted with a tandem capillary. The meaning of its "R formula" is as follows:
在毛细管的调阻段，用毛细管R8、R4、R2、R1及其对应的电磁阀在控 制系统的控制下对减振器的阻力(Resistance)进行调节的方式。其特点是：在液压缸缸体以外，依据毛细管的阻力(Resistance)特性，将串联(或者并联)的多路(可以是四路也可以是非四路)毛细管依据特定的参数(比如：面积、或者长度、或者某个工况下液压油的流动阻力等)按照一定的规则(比如：8421等比的二进制编码规则、或者其它等比或者非等比规则)排列，通过控制系统对相应毛细管的电磁阀进行控制从而达到调节阻尼的目的。以上这些就是在调阻段的“R式”的意义。In the regulation section of the capillary, the resistance of the damper is adjusted by the control of the control system using the capillary tubes R8, R4, R2, R1 and their corresponding solenoid valves. It is characterized in that, in addition to the cylinder block, depending on the resistance characteristics of the capillary, multiple (may be four or non-four) capillaries in series (or in parallel) can be determined according to specific parameters (eg area, Or the length, or the flow resistance of the hydraulic oil under certain working conditions, etc.) are arranged according to certain rules (for example: binary coding rules of 8421, or other equal ratio or non-equal ratio rules), through the control system to the corresponding capillary The solenoid valve is controlled to achieve the purpose of adjusting the damping. These are the meanings of the "R-type" in the adjustment section.
在调频段，因为我们利用毛细管调节频率的结构与方式与上述毛细管调节阻尼的结构与方式有很多相似之处，所以我们将利用毛细管及电磁阀达到调节减振器系统固有频率的方式也称为“R式”。在调频段，“R式”的意义具体解释如下：In the tuning frequency band, because the structure and the way we use the capillary to adjust the frequency have many similarities with the structure and the way of the above capillary adjustment damping, we will use the capillary and the electromagnetic valve to achieve the method of adjusting the natural frequency of the damper system. "R-style". In the tuning frequency band, the meaning of "R-type" is explained as follows:
在毛细管的调频段，用毛细管m8、m4、m2、m1及其对应的电磁阀在控制系统的控制下对减振器系统固有频率进行调节的方式。其特点是：在液压缸缸体以外，利用毛细管管径大时其阻力(Resistance)小的特性，依据毛细管的容量特性，将串联(或者并联)的多路(可以是四路也可以是非四路)毛细管依据特定的参数(比如：面积、或者长度、或容积等)按照一定的规则(比如：8421等比的二进制编码规则、或者其它等比或者非等比规则)排列，通过控制系统对相应毛细管的电磁阀进行控制从而达到通过调节参与振荡的液压油的质量进而达到调节减振器系统固有频率的目的。In the frequency band of the capillary, the natural frequency of the damper system is adjusted under the control of the control system with the capillary m8, m4, m2, m1 and their corresponding solenoid valves. The utility model is characterized in that: in the outside of the cylinder block, when the diameter of the capillary tube is large, the resistance is small, and depending on the capacity characteristic of the capillary, the multiple paths in series (or parallel) may be four or four. The capillary) is arranged according to certain parameters (such as: area, length, or volume, etc.) according to certain rules (such as: the binary coding rule of the 8421 ratio, or other equal ratio or non-equal ratio rule), through the control system The solenoid valve of the corresponding capillary is controlled to achieve the purpose of adjusting the natural frequency of the damper system by adjusting the quality of the hydraulic oil participating in the oscillation.
当减振器只要具有上述两个“R式”意义中的任意一个意义时，我们就将之称为R式减振器或者R式汽车减振器。在R式减振器中，当既有毛细管调阻段也有毛细管调频段时，其调阻段、调频段毛细管的路数可以相等，也可以不等。R式减振器的毛细管除加工成“M”形状外还可以加工成螺旋形状、“S”形状等其他形状。这几种形状仅为具体所列的几种形状，在实际应用中还可罗列出很多形状，可根据具体要求灵活而定。When the damper has any of the above two "R-type" meanings, we will call it R-type damper or R-type automobile damper. In the R type damper, when there are both the capillary adjustment section and the capillary adjustment frequency band, the number of the adjustment section and the modulation band capillary may be equal or different. The capillary of the R type damper can be processed into a spiral shape or an "S" shape in addition to the "M" shape. These shapes are only a few of the specific shapes listed, and many shapes can be listed in practical applications, which can be flexibly determined according to specific requirements.
另外，在R式减振器中，其毛细管不一定要多么细，所谓细就是指液压油流过毛细管时会产生阻力；也就是说，我们所说的毛细管就是液压油流过 时会产生阻力的油管或者油路。In addition, in the R type damper, the capillary does not have to be so fine. The so-called thin means that the hydraulic oil will flow through the capillary. That is to say, the capillary is the resistance generated when the hydraulic oil flows. Tubing or oil circuit.
