The benefits of the crawler car

Wheeled vehicles are suitable for road sections with good road conditions, which can reduce friction, increase speed and reduce energy consumption. At the same time, wheeled vehicles can carry more weight. Introduction to crawler vehicles: Tracked vehicles refer to cars driving on the track.This kind of vehicle has small unit pressure on the ground, small settlement, strong adhesion and strong driving ability.

The force area increases, the friction increases, the grip is good, and the pressure relative to the ground is reduced, which is not easy to cause the wheels to sink. And the structure is simple, sturdy and durable. And there is a pattern on the track board, and the track can be installed, so the ground can firmly hold on to rain, snow, ice or uphill without sliding.

The off-road ability of tracked vehicles is better, but the load capacity is limited. At the same time, the life of the track is short, especially in the off-road environment, and the production cost of the track is also higher than that of wheeled vehicles.

Wheeled armored vehicles have high mobility and protective performance, fast highway speed, low noise and comfortable riding, but compared with tracked armed armored vehicles, their off-road ability is poor.

First of all, the advantage of wheeled vehicles is that they are powerful and relatively light, suitable for reconnaissance missions, but the off-road ability is insufficient. Under the mediation of bad nature, it is easy to break down, such as swamps. But it is relatively convenient to maintain.

Will the use of tracks reduce friction

The force area increases, the friction increases, and the grip is good. Compared with the ground pressure reduction, it is not easy to cause the wheel to sink. And the structure is simple, sturdy and durable. And there is a pattern on the track board, and the track can be installed, so the ground can firmly hold on to rain, snow, ice or uphill without sliding.

With the increase of the force area and friction, the grip becomes better, and the pressure relative to the ground decreases, which is not easy to cause the wheels to sink.And the structure is simple, sturdy and durable. Moreover, the track plate has a pattern, and road nails can be installed, so it can firmly grasp the ground on the road such as rain, snow, freezing or uphill, etc., and will not slip.

The force area increases, the friction increases, the grip is better, and the pressure relative to the ground decreases, which is not easy to cause sinking wheels. And the structure is simple, strong and durable. Moreover, the track plate has patterns and can be installed, so it can firmly grasp the ground on rain, snow, ice or uphill and other roads without slipping.

First of all, when making tracks, you can fold the newspaper into long strips. Secondly, keep everyone's pace in line when moving forward. Finally, it is very important to stick the newspaper. The newspaper is easy to break, so you must use tape to protect it.

No. For example, cars use wheels to reduce friction; tanks have long tracks to increase friction.

The lubricant applied to the track or bicycle chain is to reduce the sliding friction between adjacent joints (or adjacent small units), joints and gears.

M semi-tracked personnel transport vehicle

1. The prototype of the M3 semi-tracked personnel transport vehicle is the T7 semi-tracked armored vehicle developed by White Motor Company in 1938. In 1940, the improved T8 of the T7 was designated as an M3 semi-tracked armored transport vehicle, and its design concept was very close to the German Sdkfz 251.

2. The M3 semi-tracked armored vehicle is a semi-tracked armored personnel carrier used by the United States during World War II and the Cold War. The vehicle is improved on the basis of the M3 armored reconnaissance vehicle and the M2 semi-tracked armored vehicle, which is better than the M2The semi-tracked armored vehicle has a longer body, an entrance and exit at the rear, and a seat that can carry a 13-person infantry squad.

Can crawlers run at 200 kilometers per hour

German SD.KFZ.250 semi-tracked armored vehicles run very fast , the maximum highway speed reaches 65km/h; the ramp that can be climbed to 24′ can wade into 0.7m deep water. The fuel reserve of the car is 140L, the maximum road journey is 350km, and the maximum off-road journey is 200km.

In addition, at high speed, the friction between the track blocks will affect its life and stability. The high speed of 200-300 is unrealistic. The energy loss of friction alone is very objective.

The maximum journey can reach 1000 kilometers.The crawler and four-axis drive wheel armored conveyor is about two meters wide across the trench and 0.5 to 1 meter high through the vertical wall. Most armored transport vehicles can drive on the water, using tracks or tires to paddle, with a maximum speed of about 5 kilometers per hour; equipped with propellers or water-sprinkled propulsion devices, the maximum speed can reach 10 kilometers per hour.

What to do if the chassis of the tracked vehicle is raised

If the car wants to be raised higher, it can only be changed to a harder spring. There is no other way, but after increasing the height, the positioning data of the wheels will change, which may cause tire biting. This data one It doesn't exist, only the modification store has it.

Strengthen the replacement of high shock absorber springs, about a few hundred yuan; the modification of pneumatic suspension is time-consuming and laborious, about tens of thousands of yuan; changing more tires, about two or three thousand yuan.I hope you can give me some help after reading the introduction of the car series about the safest lifting method of the car chassis.

The low chassis of the car can increase the height of the chassis by replacing the springs and other accessories of the shock absorber and increasing the height of the accessories to avoid the chassis from turning to the lowest when bumping, but it will increase the degree of bumping inside the car.

Method: Slow down to pass, so that the general speed bump can pass safely, unless the chassis of your car is too low.
