Description

FIELD OF THE INVENTION The invention relates to a transport engineering, primarily to tracked vehicles.

The purpose of the invention is to reduce soil compaction by leveling the plot of normal pressures beneath the thrust surface.

The caterpillar propulsion unit contains the tension and wedges, its wheels, and the caterpillar belt 1, which consists of tracks 3 connected with each other to the lugs. On each truck through the shim 4. by means of bolts 5 fixed boss 6 with a threaded hole in the center. Tracks 3 are made with brackets 7 with a hole in the center. Elastic elements 8, made in the form of a spring, are interconnected at one end through an axis 9 with tracks, and the second one with slider mechanisms 10 having an opening. A screw 11 passes through the holes in the bracket 7 and the slide mechanism 10, which is screwed into the threaded hole of the boss 6. On the screw 11 there is an elastic element 12, made in the form of a compression spring, located between the boss 6 and the slide mechanism 10.

On the axis 13 of the support rollers 2 with the help of bearings installed rollers 14 with

possibility of rotation regardless of track rollers 2.

On the beam 15 of the engine fixed brackets 16, on which the supporting rollers 17 are mounted.

Tracked propulsion works as follows.

When the tracked vehicle is moving, the torque from the drive wheel is transmitted to the tracked belt 1. The track rollers 2 move along the treadmill track. The rollers 14, mounted on the same axis with the supporting rollers, interact with the elastic elements 8, deforming them. The elastic elements 8 move the slider mechanism 10 to the right and compress the elastic element 12. The load is transmitted through the support roller to two adjacent tracks at the points of attachment of the elastic element 8. In this case, the tracks 3 do not fold, i.e. turn them relative to each other around the axis. Due to this, there is no concentration of pressures at the junction of the tracks when rolling the road wheels.

After passing by the track roller at the junction of the tracks, the elastic elements 8 and 12 unclench.

When the tensioning and driving wheels are bending around the crawler belt, the elastic elements 8 and 12 are deformed, allowing the tracks to fold relative to each other.

Claims (1)

A CRAWLER ENGINE containing tensioner and drive wheels, track rollers and a track chain enveloping them including articulated tracks with lugs, characterized in that, in order to reduce soil compaction by leveling the normal pressure plot under the support surface of the mover, it is equipped with rollers located coaxially with the support rollers, and made in the form of springs by elastic elements interacting in a vertical plane with these rollers, and each of the springs is pivotally connected two adjacent tracks, with one end of each elastic element connected to the body of one track and the other end to a slider mounted on the other track with the possibility of moving in the longitudinal direction, while another elastic element is installed between the outer side of the slider and the track body compression springs.
