Xiao Weiguo's words couldn't help but make everyone present bow their heads and ponder, indeed there are many new weapon design concepts in his words, especially people-oriented, focusing on the role and status of people. Seeing this situation, Xiao Weiguo knew that his words had worked, and maybe there would be some changes in the thinking of these German colleagues.

Xiao Weiguo continued: "Let me talk about our new tank transmission system, because we use a diesel engine, so it is relatively large, and our transmission system needs to be more delicate. It is necessary to make full use of the space of the diesel engine to achieve a high degree of integration of the transmission system and the engine, as well as the minimization of the volume, so as to increase the volume of the fighting compartment and improve the operating space of the tank crew, which is the guarantee of combat effectiveness. The location, dimensions and specific performance requirements of the drivetrains of the two tank engines have been noted in detail on our design drawings. I'd like to leave this drivetrain to Porsche, but I wonder if Dr. Porsche thinks there is a problem? ”

"It seems that the design of this traditional system is very difficult, but we at Porsche can definitely take it!" Well, on behalf of Porsche, I agree to take on this task! We are honored to be part of such a large weapons project! ”

Goodry smiled applauded: "Good, good, good!" Dr. Polscher is a senior expert in China's automotive industry, and I believe that this seemingly extremely difficult transmission system will not have any problems in your hands! I'm also looking forward to your drivetrain that will make the new tank run faster and more stable, come on! ”

Xiao Weiguo continued: "The suspension and running gear of the new tank are also closely connected to the tank engine and transmission system, and we will adopt a new suspension device, that is, torsion bar suspension. Because we use six pairs of medium-to-small diameter load wheels, and the width of the load wheels and tracks is relatively large. When using wide tracks. The ground pressure is small, and the passing ability is good; Although there is also more friction on the ground and the theoretical maximum speed decreases, our powerful diesel engine and highly efficient drivetrain mean that these are no problems. The most important thing is that we have to create precision parts for the tank crew and the tank. Provide a stable and reliable working environment. The tank will run more smoothly and will have less vibration when firing. The torsion bar is long, tough, and solid, it is a torsion spring with excellent performance, and the structure is simple, occupies a small volume in the car, it is a suspension device with good development prospects, and it is suitable for use on the tank, although there is no tank at present that dares to use this suspension device, after all, this is a new design, which needs to be tested in practice. But we dared to be the first to try, because we were sure that it would be a very advantageous design for our new tank. We hope that Galler-Benz and MAN will work together to design and develop the suspension and running gear of the new tank. ”

The people from Gallam Benz and MAN exchanged a few glances, and then Dr. Nicholas, the general manager of MAN, spoke on their behalf. I saw Nicholas stand up and said loudly: "Of course we have no problem, in the design and production of automobile chassis and locomotive running gear, both of our companies have rich experience, to make two tank suspension and running gear. There are no problems. It's just that why not use more mature suspension devices and running gear. And what about a torsion bar suspension that is not yet practical? I'm saying that the torsion bar suspension may have unexpected flaws, which will affect the performance of the new tank. ”

Xiao Weiguo said with a smile: "The shaft of the torsion bar suspension on one side is fixed on the inner wall of the other side, and the left and right sides are interactive, that is to say, the torsion bars on both sides are not centered at one end of the chassis, and the load-bearing wheels on both sides are not concentric, and the principle of the torsion bar determines the asymmetry of the load-bearing wheels." The left and right will be staggered by 200 to 300 mm. With the torsion bar suspension, when the tank moves, the load-bearing wheels roll along the road surface on the tracks. The load-bearing wheel is mounted on the balance elbow, which is fixed at one end of the torsion shaft. The load-bearing wheel moves up and down with the unevenness of the road surface, driving the balance elbow to twist using the torsion shaft. The role of the torsion shaft is mainly to slow down the impact, and its mechanism of action is to prolong the impact time, so as to reduce the impact force on the ground facing the car body when the vehicle is moving, to make the tank able to off-road at high speed, the torsion bar suspension is the best suspension device, of course, if the torsion shaft is easy to cause damage when the torsion angle is too large, so it is necessary to set up a limiting device on the car body to limit the maximum rotation angle of the torsion shaft. Overall, torsion bar suspension will become the mainstream of future tanks. We have to be the first in the world, so that we can always maintain the technological superiority of our tanks. ”

Guderian said loudly: "Mr. Philip said it very well, the reason why the tank is driving at high speed on a rough road, and the tracks or wheels jump up and down due to uneven ground, and the occupants of the car do not feel a strong peak tremor, and the reason is the role of the suspension system. The suspension system is an important part of the mobile device of the tank armored vehicle, and is the core structure of all the parts that connect the body and the load wheel of the tank armored vehicle. Specifically, its functions are mainly reflected in the following two aspects. The first is to elastically support the car body, alleviate the impact and vibration generated by the driving device on the road and transmitted to the car body, improve the working environment of the occupants in the car, and improve the work efficiency. The undulating vibration of the tank armored vehicle caused by the rough ground will seriously affect the observation, aiming and shooting of the occupants of the vehicle. At the same time, this vibration will make the occupants of the car quickly feel fatigue, nausea, dizziness, and in severe cases, it will cause damage to internal organs and greatly weaken combat effectiveness. Another function of the suspension system is to reduce the damage and destruction of vibration to the various components of the vehicle, increase reliability, so as to ensure that the tank armored vehicle can give full play to the maximum effectiveness of the power-transmission on any road surface, and ensure that it can travel at maximum speed, so that the vehicle has good maneuverability. The ability of the tank to move at high speeds on difficult terrain depends on the suspension system, in particular, the vertical travel that the suspension system provides to the load wheels. The suspension system is an important indicator for evaluating the battlefield mobility of tank armored vehicles, and when the new tank is trial-produced, it will also have to go through the assessment of our tank committee, and if the mobility index does not meet the design requirements, it will not be able to pass the appraisal. If your two companies can undertake such an important task of system design and development, they must do it in accordance with the specific requirements of the chief design unit. Do you all understand? (To be continued.) )
