General construction machinery has a telescopic crawler chassis, including a left crawler frame, a right crawler frame, a base, at least one left telescopic oil cylinder and a right telescopic oil cylinder. The left telescopic oil cylinder is installed between the base and the left crawler frame, and the right telescopic oil cylinder is installed on the base. and the right track frame.
The "pitch" of the crawler chassis: refers to the distance between the midpoints of two adjacent axles when the crawler is connected in series. The chain on your bicycle is also connected in series by shafts, and the midpoint distance between two adjacent shafts is called the pitch. The pitch on the track is measured the same way. The difference between the drive system tracked chassis in the tank:
The crawler is the motion system on both sides of the tank, with driving wheel drive and road wheel support. The chassis is the bottom of the tank, and it is a whole with the body. There are many transmission systems, such as fire control, stability, and many transmission systems in driving.
Rubber track chassis is widely used in construction machinery, tractors and other field vehicles. Bad walking conditions require the rubber track chassis to have sufficient strength and rigidity, as well as good traveling and steering capabilities. The track is in contact with the ground, and the drive wheel is not in contact with the ground. When the motor drives the drive wheel to rotate, the drive wheel continuously rolls up the track from the rear through the engagement between the gear teeth on the drive wheel and the track chain under the action of the drive torque of the reducer. The part of the track that touches the ground gives the ground a rearward force, which in turn gives the track a forward reaction, which is the driving force that pushes the machine forward. When the driving force is sufficient to overcome the walking resistance, the rollers roll forward on the upper surface of the track, so that the machine travels forward. The front and rear tracks of the rubber track chassis can be steered independently, making it a smaller turning radius.
