Compared with the conventional crawler driving technology, the crawler belt of the present invention is connected by a plurality of links, and the crawler is wound around the driving wheel, and the body is directly mounted on the upper side of the crawler by the supporting mechanism, and there is no between the lower side and the upper side of the crawler. The support, that is, the lower track that is in contact with the ground, is not connected to any rotating parts except that the two sides are connected to the drive wheels. This design is to ensure that the present invention is not as easily entangled as a conventional track with a support wheel. walk. The drive wheel is rotated by the power system through the transmission of the first chain wheel and the second chain wheel. The weight of the vehicle body of the invention is completely transmitted to the lower crawler belt by the crawler belt; the specific way is: the first chain piece and the second chain piece of the adjacent chain pieces in the track are connected by the cylindrical pin, and the hinge point is biased toward the two chain pieces. On one side, there is an elastic piece between the two links, and the two elastic pieces contact each other to generate an elastic force, so that the angle between the two links is an obtuse angle; the link with the obtuse angle can provide a bearing force for the track. In addition, there is a limiting piece on the side of the elastic piece biasing and the hinge point; after the two pieces are pressed in the direction of the obtuse angle, the pressure compresses the elastic piece, so that the angle between the links increases, and reaches a total The face, even reaching more than 180 degrees, is that the track loses its weight bearing effect. Therefore, the limiting piece is designed, and the limiting piece ensures that the two chain pieces are subjected to a force of nearly 180 degrees, and then the adjacent limiting piece produces a rigid contact to maintain an angle between the two links, and the two pieces are obtuse. The direction can be changed at will, and can be as small as an acute angle, which allows the track to be in good contact with the drive wheel for driving by the drive wheel. The angle design of the chain allows the track to bend to one side at will, while the other side needs to overcome the elastic force and bend to a certain obtuse angle, so that it can not be bent. This design can make the end-to-end connected track exert force on the upper side. The crawler maintains its distribution close to the ellipse under the elastic force of the elastic piece between the links, and the larger the force applied, the flatter the ellipse and the greater the elastic force of the crawler feedback. In the actual installation, the track installation needs to ensure that the obtuse angle of the chain is toward the inner side of the track ring. The body is supported by the track by the elliptical maintenance of the track itself, and the overall compression resistance of the upper and lower sides of the track plays a buffering and damping effect on the body. When the crawler belt is driven by the driving wheel, the body body is matched with the moving crawler by a supporting mechanism having a rotatable strut, and the rotatable strut can offset the horizontal movement of the supporting point crawler when the vehicle body presses the crawler belt. However, in this type of installation, the rigidity of the body and the chassis is poor, so that the auxiliary support mechanism is connected to the longitudinal beam on both sides of the vehicle body, so as to strengthen the vehicle when it encounters large protrusions and pits. The overall rigidity of the body and the chassis prevents the body from coming off the chassis because of insufficient strength of the track. The auxiliary support mechanism is a retractable and elastic mechanism, wherein the limit ring serves to prevent the support inner rod from sliding out of the support rod sleeve. When the road is not good, the track is crushed by the body, and the track will be The slack is changed, so the tensioning mechanism is designed to ensure that the track is always in tension and the drive is smoothly carried out. The tensioning mechanism is designed to have a telescopic function nesting structure and has pressure resistance. The purpose of the tension limiting ring design is to prevent the tensioning inner rod from sliding out of the tensioning rod sleeve. The invention improves the crawler belt, so that the crawler belt can bear the pressure of the vehicle body, and the design of the plurality of support wheels in the crawler belt is eliminated, and the general weed or the wrapable object is prevented from being wound on the support wheel, thereby causing the failure of the crawler wheel; The passability of the wheel.
