Chapter 1934: Revolution in Tank Design

Previous page        Return to Catalog        Next page

    Although in this era, the power system of all tanks was done in this way, but after the end of World War II and the entry into the Cold War period, many tank designers found that this was too cumbersome.  So they all made drastic changes at the same time.  The original engine was installed vertically, but now the engine is turned into a horizontal one, directly drives the gearbox, and finally reaches the driving wheels at the rear, so that the transmission route of the engine can be greatly reduced.  The size of the engine and transmission system has also become smaller, and the entire power transmission system can be made into a power pack, which can also be replaced directly and quickly.  Regardless of whether it is a Western or Eastern tank, all of them have designed this design in one go.

    Therefore, although Qin Baoshan is not particularly clear about the specific structure of the tank.  But he also knows what the trend of tanks is.  Especially for a small tank like my own, if the power is also transmitted to the front, it will be too complicated.  Moreover, a long transmission shaft is required. With the technology of the Eighth Route Army, it is very difficult to manufacture this transmission shaft.

    Thinking of this, Qin Baoshan also sighed.  A simple transmission shaft also has high industrial technical requirements.  In this era, the United States has a special fighter jet, the engine is arranged behind the cockpit, and the power is transmitted to the front through a transmission shaft.  This layout can only be done by Americans, because it needs to transmit more than 1,000 horsepower to the drive shaft.  Other countries simply cannot create it.  In the 21st century, the American F-35 fighter jet is even more powerful. In order to take off and land vertically, the power is drawn from the back to the lift fan, and a transmission shaft can transmit tens of thousands of horsepower.

    Now the Eighth Route Army cannot produce such things.  Just avoid it directly, and put the power system of the entire tank at the back.

    At this time, Qin Baoshan continued to draw sketches while talking.  Although the drawing is not very similar, he still drew the specific structure.  The 20-horsepower single-cylinder diesel engine is placed in the center of the rear of the tank, and behind the engine is a four-speed gearbox.  Since the engine is underpowered, this requires a gearbox with more gears.  Through the switching of different gears, the tank can travel more smoothly under different road conditions.

    Even if the designers present don¡¯t find it complicated, Qin Baoshan still wants to add an auxiliary gearbox in front of this gearbox.  Even if there is only one high and low gear, the fourth gear can be turned into eight gears.  Almost all tractor gearboxes look like this.

    However, as far as the current technology is concerned, this gearbox is a bit complicated. Qin Baoshan simply drew the schematic diagram, and the specific method is left to Ma Sanbao and the others. They manufacture cars in the United States, and have  Tanks, gearboxes are not a big deal.

    After the power system is transmitted from the gearbox, it starts to be transmitted to both sides.  In the process of transmission to both sides, there is an important side clutch, which can cut off the power of one side at any time.  In this way, the steering function of the tank can be realized.

    The steering of the car depends on the front steering wheel. The steering wheel drives the steering wheel to rotate. Whichever direction you turn, the car will go in that direction.  The tank relies on two tracks, and the tracks have no steering function, so when turning, it can only rely on the speed difference between the two tracks.  For example, if the left clutch is disconnected, the left track will lose power and the left track will stop moving.  The crawler on the right has power, continue to move forward, then the car will turn to the right.  This method is very similar to the principle of walking tractors.

    Of course, this is indeed the case on flat roads, and it may be reversed on some special roads.  For example, when going downhill, the left clutch is disconnected, and the left side loses the restraint of the engine, so it may run faster.  At this time, if you want to turn to the left, you should disengage the clutch on the right.

    When the book is in use, I hate less.  If Qin Baoshan was familiar with the structure of the walking tractor, he would have transplanted the walking tractor directly, which would be the perfect power system for the tank, and now he could only leave it to his subordinates.

    Qin Baoshan was just talking about the train of thought in detail.  He drew his own system while talking about it.  At the same time, the operation of the driver in front is ready to come out.  Like the t-34 tank, it uses a three-plate and three-bar layout, which is a classic layout that won the Stalin Award.

    The three boards are all under the feet, just like a car, they are the clutch pedal, brake pedal and accelerator pedal stepped on under the feet.  The three levers are the gear lever and the operating levers for the side clutches on the left and right.

    In this way, the power design of the entire tank has almost come out.  It doesn't need to be matched precisely, as long as it can be pulled out, as long as it can be started, and as long as there are no major problems during the starting process, then it is considered a success.  Just build cars at home with those ordinary skilled workers,The requirements are basically the same.

    What Qin Baoshan said was very important, and the people present listened very carefully.  After Qin Baoshan explained the whole system, Ma Sanbao frowned and said, "If this is the case, how should the driver operate the gearbox? How should the gear lever of the gearbox be designed?"

    In this era, the engine of an ordinary car is in the front, which transmits power to the rear tires, and the gearbox is next to the driver.  The engine of the tank is at the back, and the power is transmitted to the front through the transmission shaft, and the gearbox is also beside the driver.  Therefore, when the driver operates the gear shift, the shift lever is directly inserted into the gearbox.  But now Qin Baoshan wants to put the gearbox in the back, so there is a problem, how to change gears?

    When hearing this non-problem question, Qin Baoshan suddenly understood: Why are the power transmission routes of tanks in this era so complicated? Is it because of the gear lever?

    "This thing is not a problem at all." Qin Baoshan said casually: "We can use the gear shift lever. We can use one rod to achieve the purpose of shifting gears through the rotation and forward and backward movement of this rod. You can also use two  The gear lever simulates two operations separately."

    The operation of the shift lever is either to move left and right, or to move forward and backward. On the pull rod, as long as these two actions can be transmitted, it is enough.

    It is in this era that this problem exists.  In later generations, all vehicle gearboxes are far away from the driver.  Some are shifted by pull wires, and most cars are in this way.  The gearbox of the freight vehicle is relatively large, so the shift lever is used.

    Qin Baoshan gave a brief introduction, and the eyes of everyone present lit up, especially those technicians who came back from the United States were very amazed.  Factory Manager Qin is really amazing, he solved this problem simply and simply.  Now they are looking at the scribbled design drawing, but suddenly found that this drawing can actually be enlarged to become a medium tank, or even a heavy tank. Qin Baoshan's current design is simply of cross-epoch significance, it can be said to be a tank  A revolution in design.  (Remember the site URL: www.hlnovel.com
