3.7 The invention relates to a transport engineering, in particular to the construction of tracked propulsion. A tracked propulsion is known, which is intended to convert torque due to the thrust of the vehicle forward movement. At the same time, the thrust force realized by the propulsor on the ground with certain strength properties depend, among other things, on the distance between the lugs. Also known is a caterpillar propulsion unit containing outer and inner drive wheels, outer and inner track tracks covering them that are parallel to one another and have the same length, and the drive wheels are installed with the possibility of limited reciprocal rotation. A disadvantage of the known design is The driving force is due to the constant distance between the lugs. The purpose of the invention is to increase the traction characteristics of a crawler drive by changing the distance between the lugs. The goal is achieved by that; that in the propulsion unit containing outer and inner drive wheels mounted for limited reciprocal rotation, the outer and inner track lines arranged in parallel and having the same length are provided with a coupling mounted for transmitting torque from the output shaft of the transmissin to the outer and inner drive wheels wheels, the mutual rotation of which is limited by the stops installed on the outer and corresponding cuts in the inner driving wheels, the maximum angle of rotation in The moving wheels correspond one to the other with half of the caterpillar pitch, and the lugs located across the tracked contours and have a length equal to the total width of the external and internal tracked contours established by the cantilever of both tracked contours. In FIG. 1 is a diagram of the installation of a drive wheel VM; FIG. 2 shows a section -A in FIG. 1, in FIG. 3, a tracked bypass, bottom view, with a reduced 4-step lug, in FIG. C - the same. with the increased pitch of the lugs. The crawler propulsion contains the outer 1 and inner 2 driving KOf forests, which are driven by clutch 3. The reciprocal rotation of the driving wheels 1 and 2 is relative to each other by stops k mounted on the outer 1, and corresponding notches 5 in the inner 2 driving wheels. The outer 6 and inner 7 track lines are provided with lugs 8 and 9, respectively. Grouser 8 cantilever mounted on the track of the external crawler bypass 6, and the lug 9 on the track of the internal tracked bypass 7. The propulsion device works as follows. The torque from the output shaft of the transmission is transmitted through clutch 3, depending on its position, to the outer 1 or inner 2 drive wheel. The loaded drive wheel rotates relatively unloaded at an angle defined by the mutual position of the stop k and cutout 5. In this case, when the torque is applied to the inner drive wheel 2, the tracks of the outer 6 and inner 7 tracks follow the position shown in FIG. , and the distance between the ground and the hooks 8 and 9 is equal to the half-pitch of the track lugs if the torque is applied to the outer drive wheel 1, the tracks of the outer 6 and inner 7 tracked contours take the position shown in Fig. 4, and p ssto between the lugs 8 and 9 is equal to step caterpillars lugs. The mode of operation of the drive wheels and the distance between the lugs is set depending on the strength properties of the soil on which the vehicle operates. The use of a propeller with a variable distance between the lugs makes it possible to more fully use the strength properties of the soil to create a force of translational motion, which provides an increase in the propulsion and coupling qualities of the propeller.
