German Sd.Kfz.186 Panzerjager Tiger Ausf. B heavy tank "JagdTiger" (Porsche suspension)

The Jagdtiger tank destroyer weighs 60 tons. Corresponding to tanks of the same weight, German tank design factories generally use torsion bar suspension systems. The reason is that the load-bearing capacity of this system is very high, and the torsion bars are arranged one by one from the front to the rear of the car. But the disadvantage is that it takes up a lot of space. Tanks and combat vehicles need to store the driver's daily necessities, sufficient ammunition, equipment tools, etc. in the thick steel plate, so there is not much storage space, and the torsion bar shock absorber The biggest problem with the system is that it reduces the remaining usable space in the tank cabin.

Many mechanical engineers have optimized the design of torsion bars to varying degrees, but until the emergence of a unique Austrian-born genius mechanical engineer, Dr. Ferdinand Porsche, he overturned the traditional design concept and designed a new type of torsion bar. The suspension system is installed on both sides of the car bottom, and there is no need to penetrate the internal structure of the car bottom. Its purpose is to make the maintenance process more convenient, and the weight of the entire suspension system is even lighter than the traditional torsion bar, which is relatively The production cost is also cheaper. In fact, Dr. Porsche also adopted the core design principles of the torsion bar, and then designed the layout more carefully, using a design combination of bevel gears to imitate the mechanical principle of the torsion bar. Although the Porsche-type suspension system was not widely used in the end, the ingenuity of its design is definitely worthy of admiration by future generations.
