FIELD: transportation; agriculture.

SUBSTANCE: tractor comprises front axle unloading sensor hydraulically connected with spool-type device and weight transfer unit with ballast weight and hydraulic cylinder. The said front axle unloading sensor is cinematically connected with spool-type device which is hydraulically connected with weight transfer unit with ballast weight located on the front axle. Bracket to which weight transfer unit with ballast weight is attached is connected with hydraulic cylinder rod to allow fluid drain into tank and for direct adjustment of front axle load.

EFFECT: straight-line stability improvement, tractor aggregate drivability improvement and quality improvement of agricultural operations.

FIELD: agriculture.

SUBSTANCE: monoblock assembly contains an upper side, base, two sides disposed perpendicular to the direction of the tractor movement and two lateral sides disposed parallel to the movement direction. Each lateral side contains a cargo bolt or cross axis which services as a suspension for lifting tractor. The assembly contains at least one cavity having opened ends and placed so that being able to accept one lifting bracket of the device for freight handling which allows lifting and removing the assembly upon interacting the cavity with the lifting bracket.

EFFECT: simplification of monoblock assembly displacement.

Caterpillar // 2450951

FIELD: transport.

SUBSTANCE: invention relates to agricultural tractors caterpillar ganged up with tools by means of rear suspension. Proposed tractor comprises frame 1, suspended working tools driven by hydraulic cylinder 3, means for shifting tractor center of pressure including two levers 4 secured at frame front and counterweight arranged on said levers 4. Counterweight is made up of vessel 5 with ballast 6 and arranged to reciprocate on levers 4. Reciprocation is executed by rollers 7 and counterweight hydraulic drive made up of two lateral hydraulic cylinders 8. Like chambers of hydraulic cylinders 3 and 8 are intercommunicated via lines and, via hydraulic control valve 9, with pimp 10 and hydraulic tank 11. Aforesaid vessel 5 is provided with cover 12 for ease of ballast unloading.

EFFECT: required centering of tractor gravity center.

SUBSTANCE: adjustment device of ballast weight position includes transmitter of tractor front axis (1) unloading. Transmitter is made in the form of an electric force-measuring pin with electronic control unit (2), into which the required sensitivity level of front axis (1) unloading transmitter is programmed. When the tractor front axis is unloaded above allowable level, transmitter supplies the signal to electronic control unit that generates a control signal and supplies it to electric hydraulic valve (10). Electric hydraulic valve is connected on one side to hydraulic cylinder (7), and on the other side via hydraulic lines (12) and (13) to pressure line of hydraulic system of tractor and drain line. Depending on the signal supplied to electric hydraulic valve (10), hydraulic cylinder (7) connected to it moves beam (4) with ballast weight (6) now in tractor movement direction, and then to initial position.

EFFECT: invention allows increasing the stability of straight-line movement, improving the controllability of hinged tractor unit, improving the uniform distribution of vertical loads on supports of the unit and improving sensitivity of the system actuation.
