Description
本發明係關於油電混合動力之技術領域，特別係關於一種能夠量測混合動力系統的動力之量測系統。 The invention relates to the technical field of hybrid electric power, in particular to a measurement system capable of measuring power of a hybrid power system.
目前工業上提供兩種主要動力輸出來源，一種為汽柴油等燃料動力的引擎11，而另一種則以電力為主要動力輸出的馬達12，一般引擎11的轉速約在700rpm~8000rpm，而馬達12的轉速則在500rpm~3000rpm； 一般混合動力量測系統10的結構如圖1所示，引擎11及馬達12共同連接至傳動軸13，傳動軸13再連接至動力計14，引擎11及馬達12的動力共同傳遞至傳動軸13後，再藉由動力計14量測其引擎及馬達混合後的馬力。 At present, the industry provides two main power output sources, one is a gasoline-diesel-powered engine 11 and the other is a motor 12 that uses electric power as the main power output. Generally, the speed of the engine 11 is about 700 rpm to 8000 rpm, and the motor 12 The speed is between 500rpm and 3000rpm; The structure of a general hybrid measurement system 10 is shown in FIG. 1. The engine 11 and the motor 12 are connected to the transmission shaft 13 in common, and the transmission shaft 13 is connected to the power meter 14. The power of the engine 11 and the motor 12 is transmitted to the transmission shaft 13 together. Then, the power of the engine and the motor is measured by the power meter 14.
然而，當引擎11的轉速超過3000rpm後，由於馬達12無法提供更高的轉速，意即，傳動軸13僅會傳遞引擎11的動力，而動力計14僅能量測到引擎11的馬力；同樣地，當馬達12轉速低於700rpm時，由於引擎11無法提供更低的轉速，造成傳動軸13僅傳遞馬達12的動力，更甚者，一般動力計14能夠量測的轉速是在1000rpm~10000rpm，當傳動軸13傳遞的轉速低於1000rpm時，動力計14將無法量測其馬力。 However, when the speed of the engine 11 exceeds 3000 rpm, the motor 12 cannot provide a higher speed, which means that the transmission shaft 13 will only transmit the power of the engine 11 and the power meter 14 only measures the horsepower of the engine 11; When the speed of the motor 12 is lower than 700 rpm, the engine 11 cannot provide a lower speed, so that the transmission shaft 13 only transmits the power of the motor 12, moreover, the speed that the general power meter 14 can measure is between 1000 rpm and 10000 rpm. When the transmission speed of the transmission shaft 13 is lower than 1000 rpm, the power meter 14 cannot measure its horsepower.
有鑑於混合動力量測系統10的量測尚有缺陷，故應提供一種能夠量測混合動力量測系統10的動力之量測平台，使引擎11及馬達12的動力能夠同時傳遞至動力軸，並能夠為動力計14所量測其混合動力後之馬力。 In view of the shortcomings of the measurement of the hybrid measurement system 10, a measurement platform capable of measuring the power of the hybrid measurement system 10 should be provided so that the power of the engine 11 and the motor 12 can be transmitted to the power shaft at the same time. And it can measure the horsepower of its hybrid power for the power meter 14.

本發明之第二個目的在於，解決引擎及馬達的轉速範圍與動力計的轉速範圍不同，造成轉速在不符合動力計轉速範圍時，動力計無法量測之缺失。 The second object of the present invention is to solve the difference between the speed range of the engine and the motor and the speed range of the power meter, which causes the lack of measurement of the power meter when the speed does not conform to the speed range of the power meter.

藉此，該引擎20輸出一第一馬力，該第一馬力具有一第一扭力及一第一轉速，該馬達40輸出一第二馬力，該第二馬力具有一第二扭力及一第二轉速，該第一馬力輸入該第一變速箱30，藉由該第一變速箱30降低該第一轉速並相對提升該第一扭力，使該第一轉速與該第二轉速相等並傳送至該傳動軸進行動力混合而產生一第三馬力，該第三馬力具有一第三扭力及一第三轉速，該第三馬力輸入該第二變速箱60，藉由該第二變速箱60降低該第三轉速並相對提升該第三扭力後再輸入該動力計70。 Thereby, the engine 20 outputs a first horsepower, the first horsepower has a first torque and a first rotation speed, the motor 40 outputs a second horsepower, the second horsepower has a second torque and a second rotation speed The first horsepower is input to the first gearbox 30, and the first gearbox 30 is used to reduce the first speed and relatively increase the first torque, so that the first speed is equal to the second speed and transmitted to the transmission The shaft performs power mixing to generate a third horsepower, the third horsepower has a third torque and a third speed, the third horsepower is input to the second gearbox 60, and the third gearbox is lowered by the second gearbox 60. After the speed and the third torque are relatively increased, the power meter 70 is input.
以上為本發明之結構組態及其連接關係，本發明之使用方式如下所述：該第一變速箱30及該第二變速箱60即為一般的變速箱，即是藉由齒比改變轉速及扭力；一般公制馬力計算的公式如下：馬力(PS)=扭力(kg-m)×引擎轉速(rpm)/736 The above is the structural configuration and connection relationship of the present invention. The use manner of the present invention is as follows: the first gearbox 30 and the second gearbox 60 are general gearboxes, that is, the rotation speed is changed by the gear ratio. And torque; general metric horsepower calculation formula is as follows: horsepower (PS) = torque (kg-m) × engine speed (rpm) / 736
請參閱圖3，在本實施例中，該引擎20輸出馬力100(PS)，且該引擎20轉速為5000rpm，藉由前述公式可以得知，該引擎20的扭力為14.72(kg-m)，然而，該引擎20輸出的轉速5000rpm遠大於該馬達40能夠輸出的轉速轉速；該第一變速箱30將該引擎20的轉速調整為3000rpm，在輸出的馬力不變的前提下，由前述公式可以得知，經過該第一變速箱30後，該引擎20的扭力改變為24.53(kg-m)並傳遞至該傳動軸50；該馬達40輸出轉速3000rpm之馬力至該傳動軸50； 由於該引擎20及該馬達40的轉速相同，因此，該引擎20及該馬達40的馬力於該傳動軸50中混合；由於轉速3000rpm於該動力計70能夠量測的範圍內，故該傳動軸50的動力經過該第二變速箱60時不調整；該傳動軸50將動力直接傳遞至該動力計70，藉由該動力計70量測出該引擎20及該馬達40混合後的動力。 Referring to FIG. 3, in this embodiment, the engine 20 outputs 100 horsepower (PS), and the engine 20 rotates at 5000 rpm. According to the foregoing formula, it can be known that the torque of the engine 20 is 14.72 (kg-m), However, the rotational speed of 5000rpm output by the engine 20 is much greater than the rotational speed of the motor 40; the first transmission 30 adjusts the rotational speed of the engine 20 to 3000rpm. Under the premise that the output horsepower remains unchanged, the above formula can It is learned that after the first gearbox 30, the torque of the engine 20 is changed to 24.53 (kg-m) and transmitted to the transmission shaft 50; the motor 40 outputs a horsepower of 3000 rpm to the transmission shaft 50; Because the rotation speed of the engine 20 and the motor 40 are the same, the horsepower of the engine 20 and the motor 40 is mixed in the transmission shaft 50; because the rotation speed is 3000 rpm within the range that can be measured by the power meter 70, the transmission shaft The power of 50 is not adjusted when passing through the second gearbox 60; the transmission shaft 50 directly transmits the power to the power meter 70, and the power of the engine 20 and the motor 40 is measured by the power meter 70.
請參閱圖4，在另一個實施例中，該引擎20輸出馬力25(PS)，且該引擎20的轉速為700rpm，由前述的公式能夠得知，該引擎20的扭力為26.29(kg-m)；而該馬達40欲輸出轉速500rpm之動力，故該馬達40將動力傳遞至該第一變速箱30後，該第一變速箱30將該引擎20的轉速調整為500rpm，在馬力不變的情況下，藉由前述公式可以得知，扭力調整為36.8(kg-m)，並將該引擎20調整後的動力輸出至該傳動軸50；該馬達40輸出轉速500rpm的馬力至該傳動軸50；該引擎20及該馬達40共同將相同轉速的馬力傳遞至傳動軸50後混合；由於轉速500rpm小於該動力計70能夠測量的最小轉速，故該第二變速箱60將該引擎20及該馬達40的共同轉速500rpm調整至1000rpm，使其能夠為該動力計70所測量。 Referring to FIG. 4, in another embodiment, the engine 20 outputs 25 horsepower (PS), and the rotation speed of the engine 20 is 700 rpm. According to the foregoing formula, it can be known that the torque of the engine 20 is 26.29 (kg-m ); And the motor 40 wants to output a power of 500 rpm, so after the motor 40 transmits the power to the first gearbox 30, the first gearbox 30 adjusts the speed of the engine 20 to 500 rpm, and the horsepower does not change In the case, it can be known from the foregoing formula that the torque is adjusted to 36.8 (kg-m), and the adjusted power of the engine 20 is output to the transmission shaft 50; the motor 40 outputs horsepower at a speed of 500 rpm to the transmission shaft 50 The engine 20 and the motor 40 jointly transmit the horsepower of the same speed to the transmission shaft 50 and mix them; since the speed of 500 rpm is less than the minimum speed that the power meter 70 can measure, the second transmission 60 combines the engine 20 and the motor The common rotational speed of 40 is adjusted from 500 rpm to 1000 rpm, so that it can be measured by the power meter 70.
藉由該第一變速箱30，使該引擎20及該馬達40的轉速相同，進而使該引擎20及該馬達40的動力均能夠於該傳動軸50上混合； 而藉由該第二變速箱60，能夠改變該傳動軸50的轉速，進而使該動力計70能夠量測該傳動軸50馬力。 By using the first gearbox 30, the rotation speeds of the engine 20 and the motor 40 are made the same, so that the power of the engine 20 and the motor 40 can be mixed on the transmission shaft 50; With the second gearbox 60, the rotation speed of the transmission shaft 50 can be changed, so that the power meter 70 can measure the 50 horsepower of the transmission shaft.
