Description

The invention relates to traction machines operating with trailed equipment.

The purpose of the invention is to increase productivity by equalizing the vertical loads on the supporting surfaces t ga при while increasing its grip weight.

In Fig.1 depicts a tacho with trailer equipment; FIG. 2 shows the node I in FIG. on fig.Z - installation diagram hydrocyli Ndra; Fig. 4 is a hydraulic drive circuit of a hydraulic cylinder.

The trailed scraper contains a taller 1, connected with a trailed bucket 2, a hitch 3. Between the traction beam 4 and the arch-trunk of the trailed bucket 2, there is a hydrocyline, etc., 5 which is connected to them with the upper 6 and lower 7 forks or ball joints. Upper fork 6 has two mutually perpendicular swivel joints 8 and 9, which connect it to hydraulic cylinder 5 and trailer bucket frame 2. Lower fork 7 has two intersecting swivel joints 10 and 11, which connect it to hydraulic cylinder 5 and drawbar 4. The pivot points 7 and 10 are perpendicular to each other and with the axis of the hydraulic cylinder 5.

The unloading device operates in a sledding manner. In the transport mode, the gacha 1 hydraulic cylinder 5 is in the floating position, which ensures all

necessary reciprocating movements of the traction beam 4. and the trailed bucket 2 when driving on rough terrain, Turns of the traction timber 4 in

on the 90 plane in both directions, the relative trailed bucket 2 and the latter is rocked in the vertical plane by fastening the hydraulic cylinder 5 with the help of forks 6 and

7, having two mutually perpendicular hinges or ball joints,

On the go mode (when typing

soil scraper or high road resistance) in the hydraulic cylinder 5 serves adjustable oil pressure, which is automatically maintained by the pressure valve. Wherein

 The hydraulic cylinder ick 5 extends and, through the drawbar 4, depresses the hitch 3 tons 1. As a result, the normal reactions are redistributed

between wheels t gacha 1 and front axle of the trailed bucket 2 up to its gtolnogo vyveEg baths. During the work of the burner / burning device, there are no horizontal forces

By redistributing normal loads on the wheels with a gacha 1, even with constant coupling weight, it therefore reduces the unevenness of redistribution.

normal wheelies on wheels t gacha I with an increase in its coupling. .weight
