如图2所示，本发明一种装载机再生制动系统关键参数匹配方法，按照下述步骤进行：As shown in Figure 2, a method for matching key parameters of a loader regenerative braking system according to the present invention is carried out according to the following steps:
首先，根据改造空间确定耦合器的位置，然后结合泵马达系列初步确定泵马达的排量范围(排量越大所需改造空间越大)；Firstly, determine the position of the coupler according to the reconstruction space, and then preliminarily determine the displacement range of the pump motor in combination with the pump motor series (the larger the displacement, the greater the reconstruction space required);
然后，从初步选定的泵马达排量的最小值开始计算对应排量下的耦合器传动比极限值ip，然后根据耦合器传动比极限值ip、最小工作压力P1和泵马达排量qh计算泵马达提供的再生制动力矩TP/M；Then, start from the minimum value of the initially selected pump motor displacement to calculate the coupling transmission ratio limit value ip under the corresponding displacement , and then according to the coupling transmission ratio limit value ip , the minimum working pressure P1 and the pump motor displacement qh calculates the regenerative braking torque T P/M provided by the pump motor;
将原车制动力矩作为目标制动力矩T与之相比，若TP/M>T，则选择该排量的泵马达和对应条件下的耦合器传动比ip；若TP/M<T，判断该排量下的泵在倒档最大车速下是否能满足目标制动力，若满足则确定选择该排量的泵马达和对应条件下的耦合器传动比ip，若无法满足就提高泵马达排量并按照之前的步骤进行匹配计算；Compare the braking torque of the original vehicle as the target braking torque T, if T P/M > T, then select the pump motor with the displacement and the coupling transmission ratio i p under the corresponding conditions; if T P/M <T, judge whether the pump under this displacement can meet the target braking force at the maximum speed of the reverse gear, if so, determine the pump motor with this displacement and the coupler transmission ratio ip under the corresponding conditions, if not, then Increase the displacement of the pump motor and perform matching calculations according to the previous steps;
当所有的排量的泵马达都无法满足将原车制动力矩作为目标制动力矩T时，则将根据国标制动距离计算的国标制动力矩作为目标制动力矩，然后按照之前的方法进行匹配计算。When the pump motors of all displacements cannot satisfy the original vehicle braking torque as the target braking torque T, the national standard braking torque calculated according to the national standard braking distance is used as the target braking torque, and then proceed according to the previous method match calculation.
最后得到泵马达排量qh、耦合器传动比ip和能量回收的最大车速。Finally, the displacement qh of the pump motor, the transmission ratio of the coupling i p and the maximum vehicle speed of energy recovery are obtained.
在进行参数匹配之前需要确定制动能回收再生系统与原装载机传动系统的耦合位置和液压液压泵马达可选排量的确定；Before parameter matching, it is necessary to determine the coupling position of the braking energy recovery regeneration system and the original loader transmission system and the determination of the optional displacement of the hydraulic pump motor;
结合选定的液压泵马达系列与装载机可供改造的空间，初步确定该系列液压泵马达能够满足改造空间的最大排量，这是因为排量与液压泵马达的体积有直接关系；Combining the selected series of hydraulic pump motors and the space available for transformation of the loader, it is preliminarily determined that this series of hydraulic pump motors can meet the maximum displacement of the transformation space, because the displacement is directly related to the volume of the hydraulic pump motor;
确定制动能回收再生系统与原装载机传动系统的耦合位置，这时可以得知车速v与制动能回收再生系统输出轴转速na的传动关系：Determine the coupling position between the braking energy recovery and regeneration system and the original loader transmission system. At this time, the transmission relationship between the vehicle speed v and the output shaft speed n a of the braking energy recovery and regeneration system can be known:
na＝iavn a =i a v
结合选定系列液压泵马达各排量对应的许用转速nmax与制动能回收工况的最大车速vmax，确定耦合器传动比极限值；Combining the allowable speed n max corresponding to each displacement of the selected series of hydraulic pump motors and the maximum vehicle speed v max under braking energy recovery conditions, determine the limit value of the transmission ratio of the coupler;
结合极限传动比ip与液压泵马达排量计算液压泵马达在最低工作压力下所能提供的再生最大制动力矩；Calculate the regenerative maximum braking torque that the hydraulic pump motor can provide under the minimum working pressure by combining the limit transmission ratio i p and the displacement of the hydraulic pump motor;
将求得的对应排量下的再生制动力矩与目标制动力矩比较，确定满足目标制动力矩的液压泵马达排量作为液压泵马达排量的匹配结果；Comparing the obtained regenerative braking torque under the corresponding displacement with the target braking torque, determining the displacement of the hydraulic pump motor that satisfies the target braking torque as the matching result of the displacement of the hydraulic pump motor;
若液压泵马达所有可选排量产生的再生制动力矩都无法满足目标制动力矩，则降低目标制动力矩的要求，重新进行液压泵马达排量的匹配；If the regenerative braking torque generated by all optional displacements of the hydraulic pump motor cannot meet the target braking torque, reduce the requirement for the target braking torque and re-match the displacement of the hydraulic pump motor;
目标制动力矩分为两种：(1)原车行车制动力矩；(2)使装载机制动距离符合国标制动距离的国标制动力矩；The target braking torque is divided into two types: (1) the driving braking torque of the original vehicle; (2) the national standard braking torque that makes the braking distance of the loader conform to the national standard braking distance;
确定液压泵马达排量和制动能回收再生系统工作工况后可以将动力耦合器的档位进行分配，然后根据各档位的最大车速与液压泵马达许用转速进行传动比匹配；After determining the displacement of the hydraulic pump motor and the working conditions of the braking energy recovery regeneration system, the gears of the power coupler can be allocated, and then the transmission ratio is matched according to the maximum vehicle speed of each gear and the allowable speed of the hydraulic pump motor;
在确定制动能回收再生系统工作工况后，根据制动能回收工况最大车速下的动能进行蓄能器容积的匹配，如图3所示。After determining the working condition of the braking energy recovery regeneration system, the volume of the accumulator is matched according to the kinetic energy at the maximum speed of the braking energy recovery working condition, as shown in Figure 3.
首先，根据装载机重量和车速计算装载机动能；First, calculate the loader energy based on the loader weight and vehicle speed;
然后，根据蓄能器充气压力、最小工作压力、最大工作压力推导蓄能器容积与蓄能器存储能量的关系；Then, deduce the relationship between the volume of the accumulator and the stored energy of the accumulator according to the accumulator charging pressure, the minimum working pressure and the maximum working pressure;
最后，将装载机动能作为已知条件求出蓄能器容积并圆整。Finally, take the energy of the loader as a known condition to find the volume of the accumulator and round it off.
以上所述仅为本发明在并联式混合动力装载机参数匹配中应用的一个实例，对于本技术领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above description is only an example of the application of the present invention in the parameter matching of parallel hybrid power loaders.
