On the screen, people can often see the performance of tanks crossing obstacles. I saw a huge main battle tank "brush" driving over, climbed up the earth ridge at high speed, soared up along the slope, flew high off the ground and landed firmly on the ground. In the wilderness, the tank can still walk on the ground. Why can it have such superb skills?
Tank is a vehicle that uses crawler movement. Compared with wheeled vehicles, its advantage is that the contact area between crawler and ground is larger, which is not easy to slip or sink on soft ground. Therefore, it can support heavier vehicle body and gallop on the wilderness without road.
The movement of tank is realized through the interaction between track and ground. When the tank starts, the power of the engine drives the driving wheel to rotate through the transmission device, and the climbing teeth of the driving wheel move the lower support track, which moves backward relative to the tank. However, due to the large friction between the ground and the track, the track will not move relative to the ground, so the tank body "sitting" on the track will move forward relative to the ground. If the tank accelerates or falls into the mud, and the friction between the ground and the track is not enough, we will see that the tank track is turning "noisily", but the tank can't move.
The tank can drive at high speed on the barren mountains, but also thanks to the strong engine, strong armor shell and strong suspension device. In cross-country high-speed driving, the ground resistance is very large, the turbulence is also violent, and the additional impact force on the tank is very large. At this time, the powerful power of the engine can ensure that the tank can overcome great ground resistance; The solid shell and suspension device can ensure that it can withstand the additional impact and will not be damaged. The power of contemporary main battle tank engine is as high as 1100 kW. If this power is used for power generation, it is enough to ensure the total power consumption of more than 200 households (based on the total power of 5 kW per household), and its energy can be imagined.
