Type 10 MBT-X - Mobility
A newly developed 1,200-horsepower V-type 8-cylinder, 4-cycle water-cooled diesel engine was adopted. The latest technology, such as an electronically controlled unit injector , variable nozzle exhaust turbocharger , and ceramic coating , has been generously incorporated into this engine, achieving high output despite its small size and light weight. In addition to this, the world's first hydromechanical continuously variable transmission (HMT) was introduced as a main battle tank for the transmission, which made it possible to obtain the optimum gear ratio in every rotation range, and the transmission efficiency from the engine was improved. Significantly improved. The HMT of the Type 10 tank is a combination of a 3-speed stepped transmission and a hydraulic stepless transmission.
Compared to the 90-type tank, the engine output is reduced due to the reduction in the number of cylinders, but thanks to the reduction in the body weight, the output-to-weight ratio is 27.7hp /t . This is a value equivalent to Leclerc of France and Leopard 2A4 of Germany, and it is a high figure even from a global perspective . Even if the armor increases to about 50 tons, the power-to-weight ratio is 24 hp/t, which is equal to or higher than the Leopard 2A6M and the US M1A2 SEP , so it can be considered that there is no problem with mobility. And since the transmission efficiency has been increased by the new technology mentioned above, the sprocket output per unit weight is said to be dramatically improved even with the same output to weight ratio, and mobility is higher than before.
The maximum speed when moving forward is 70km/h, which is the same as the Type 90 tank, but the Type 10 tank can reach a speed of 70km/h even when moving backward. (Type 90 tank is about 50km/h)
The radiator exhaust port is in the center of the vehicle body, and the engine exhaust port is next to it.
The APU exhaust port is under the left end cover.
In addition, the left rear of the vehicle is equipped with an APU (auxiliary power unit), which was not found in the 90-type tank, and is believed to cover the increased power of electronic devices, reducing fuel consumption during standby. The installation of an APU is a recent tank trend, and the US M1 is also equipped externally from M1A1, M1A2SEP is equipped with it, and the German Leopard 2 is also equipped with the latest A7 + .
The suspension system of the Type 10 tank is an all-wheel hydraulic suspension similar to that of the Type 74 tank, making it possible to tilt the vehicle body forward, backward, left and right. In Japan, a semi-active suspension was prototyped in 1989, and an active suspension was prototyped in 1994, and experiments were repeated using the tracked test vehicle MRV. It was said that it was adopted, but it was not adopted after all.
Although it is a passive type, the performance of the suspension system has been improved compared to the previous model, and the prototype vehicle can shoot stably even when the module armor is removed and it is lightweight. Participated in the 2012 Fuji General Firepower Exercise, demonstrating advanced shooting performance such as shooting while slaloming, which was not possible in the past.
