Chassis (transmission) and tractor controls

The MTZ model 1523 tractor is equipped with a working and parking brake system. The actuators are installed on the drive gear shafts of the final drives.

The service brakes are divided into right and left and are operated by two pedals using a hydrostatic drive.

The parking system is activated by a fixed lever using independent mechanical rods. There is a pneumatic drive for the brakes of the trailer or towed equipment, the compressor of which is also used to inflate tires.

The steering of the Belarus tractor is hydrostatic, which can significantly reduce the effort when performing maneuvers.

The system consists of the following elements:

dispenser pump;
double-rod working cylinder;
pump driven by a diesel engine and hydraulic system;
oil containers with fine filter.

The mount is designed in such a way as to be able to control the movement of the tractor in reverse mode from the rear operator's workplace.

The transmission of the MTZ-1523 tractor is mechanical and includes the following elements:

The clutch is a dry double-disc clutch, permanently closed. The control is a pedal, the drive is hydrostatic.
Rear axle, the design consists of a main gear, a differential with a locking function, two final drives and final drives.
The front axle, the drive axle, is in the form of a cast beam, in which there is a main gear housing with drive and driven gears.

The chassis of the Belarus-1523 tractor is highly reliable and easy to use. The wheels are mounted on hubs, the design of which allows changing the track of the agricultural machine. On the front axle, the distance is increased or decreased by rotating the disk 180°, on the rear axle - by moving the unit along the axle shaft. To improve cross-country ability, it is possible to install dual wheels.

Design, types and applicability of FDA drive hydraulic valves

The hydraulic valves used in Belarus tractors are designed quite simply. They consist of a spool-type solenoid valve and a block in which a vertical channel is machined for the spool, as well as inlet and outlet channels. The spool can have two positions:

• Spool lowered - in this position, the spool closes the drain channel, but connects the inlet and outlet channels, so oil from the pump enters the fluid coupling; • Spool raised - in this position, the spool closes the inlet channel, but connects the outlet and drain channels, so the oil from the fluid coupling goes to the drain.

The solenoid valve is controlled using a button located on the remote control in the cab. To connect the valve winding to the electrical circuit, a connector (plug) is provided on the hydraulic distributor body. The hydraulic distributor is mounted on the gearbox cover using four bolts; for this purpose, four through holes are provided in its body.

Today, tractors Belarus-1221, 1532 and others use hydraulic valves of three types:

• Series RH06101-012 (manufactured by BADESHTNOST, Bulgaria); • Series 1РГЭ-6Т (manufactured in Gomel, Republic of Belarus); • MRE6-T574 series (manufactured by DUET Gidravlik LLC, Yaroslavl).

All hydraulic valves have an identical design and characteristics, that is, they are analogues of each other, and therefore can be used on Belarus-1221 and 1532 tractors without any restrictions.
