DT-75 tractor description

From any side, the engine tractor DT-75 is closed with a hood from moisture and dirt. In its frontal part, radiators (for water and oil) are placed, closed with a special curtain of tarpaulin. In the back of the engine there is a power transfer with the main clutch of the clutch, a powerful cardan transmission (it is connective), rear axle, torque amplifier, gearbox. All this is collected in a single cast case. Nearby are the dependent power selection shaft with end gears.

A planetary increase in the moment of force on this tractor gives an increase of 25% of the tractive effort on any of the gears, however, by reducing the speed of movement of the machine. Thanks to this mechanism, the DT-75 tractor easily passes short-term difficult areas that prevent its movement, without having to stop or switch to a lower transmission. The magnifier gives a tractor 2 additional transmissions at a rate of less than 5 kilometers per hour and a thrust force of more than 3.

The mechanical box has 7 gears: the main gear is equipped with two conical gears, and on-board - two cylindrical gears. The planetary rotary mechanism is built into the rear axle, and the entire design along with the box is collected in a single cast case: it made it possible to make a more rigid frame and provide transmissions to work in more clear conditions. A pair of planetary rotary mechanisms (single-stage), equipped with a ribbon brake is located in the rear bridge.

The shaft, selecting the power for mounted guns, belongs to the dependent form: the rotational power is transmitted to it through the gearbox, placed on the rear wall of the transmission shell, from the main shaft in the magnifier of the moment of force. To activate or disconnect the bag, you do not need to leave the cab - the lever that activates it is in the tractor driver cabin.

A sufficiently rigid welded frame consists of a pair of welded longitudinal spars with a rectangular closed cross section, which are connected to each other perpendicular axes and bars. This frame has become a reason for strengthening all major major tractor mechanisms. Its rear brackets hold the trailed mechanism and a lever-hinge device of the samples along with the power cylinder of the entire hydraulic system, so that the tractor driver can control the work of all guns directly from its workplace and completely independently.

Steering wheels, rollers with rubber bandage, carriages suspension and caterpillar circuit make up standard tractor. Seven-covering tracks of the caterpillars are interconnected with steel fingers and are equipped with a treadmill overlap, which allows rollers to gently and smoothly roll along the chain.

DT-75 Tractor Cab

Cabin closed driver: It has a pair of soft seats, and the driver's seat cushion has an adjustable support. From the water radiator, an air liner was conducted for heating and a fan was installed to compose air in the cab. For the driver, there are pedals and levers to control the machine: the hydraulic distributor lever and the power take-off shaft, the Mass Switch, Switches, the button for the electric signal, the battery, the battery, the water tank, tools and the first-aid kit. Behind the cabin is a fuel tank.

The tractor is equipped with a device for direct current With a voltage of 12 V. From the optics, there is a pair of headlights and a pair in the rear, a lighting lamp in the cabin, a lamp for the control instrument panel. It is possible to connect remote light and portable lamp. Thanks to the tractor equipment, a concept is implemented that allows the driver and contact the trailers through the audio electrose.

The popularity of Tractors and DT-75 bulldozers has long been proven by exceptional reliability, simplicity of repair and low price. In order to expand the functionality, it is possible to buy and use various attachments. Nowadays, components and spare parts for new tractors DT-75 produce many specialized enterprises and no longer constitute any difficulties with their acquisition in any region of Russia.

Small weight and wide tracked canvas, provided cars good permeability and maneuverability. Thanks to these features, the DT-75 tractor is most widely used for field work and on logging.

Device machine

The first models of DT-75 were installed four-cylinder diesel engines of the SMD-14. These aggregates issued power in 75 horse power And possessed a working resource in 3000 hours.

Tractor DT 75.

Subsequently, the power plant was replaced by an improved engine from this SMD-14NG series. The new engine possessed the same technical characteristicsAs his predecessor, but betrayed more power - 80 horsepower.

For the operation of equipment in the regions with a cold climate and work in winterThe engine of cold starting engine was provided. In the history of its existence, the tractor was modified several times. For the second generation of machines, more powerful diesel units were installed.

The base for the DT-75 tractor serves a metal composite frame. It consists of two side meters that are interconnected metal pipes. The main nodes of the tractor are attached to the frame: roller mechanisms, suspension, tracked trolleys, blocks of guide and leading rollers.

Transmission of the machine consists of four chassis boxes Transmissions, two-disc clutch clutches of closed type and ribbon floating brakes. The gearbox provides 7 front and one rear speed.

To increase traction indicators, a stroke decrease was installed on the tractor, a single-stage reverse gearbox and a planetary gearbox to increase the torque. It was these features that allowed to install dump and use the machine as a bulldozer.

Installed on the caterpillar tractor and the Power (power takeoff shaft), the drive was driven by a leader and whether the reducer to increase the torque. By the way, these nodes were mounted on the front wall of the gearbox, but were highlighted in a separate unit.

Tractor DT 75 N

DT-75 tractor had a double tight cabin. High tightness ensured protection against noise and dust. The driver's seat had the ability to change its configuration. For comfortable work, ventilation and heating systems were installed. The safety frame was responsible for the safety of the driver.

Various target units can use as attachments to the DT-75 tractor. This contributes to the trailer, the rear hood and the hydraulic system of separate-aggregate type. This gives the machine the opportunity to use a plow, a bulldozer, a seeder of the harrow and a device for cleaning potatoes.

In addition, the car can be aggregated with additional equipment of the side semi-mounted type. This allows you to turn the tractor into a concrete-layer or loader. A wide range of DT-75 capabilities includes road, construction and drilling work.

Principle of operation

If desired, the DT-75 Bulldozer operator may calculate the time cycle of the bulldozer, which consists of such items as:

1. Working stroke with the deepening and soil cooker, i.e., the set and movement of a certain amount of soil to the discharge site occurs.
2. Termination of movement to switch speeds.
3. Idling to return to the original position for the coppe.
4. Stop to go to the front turn.

Cropped and separated from the main surface, the soil is assembled before the knife to the top level of the working body, after which the dummy mechanism rises to the level of the earth's surface and the contents simply moves to the discharge site.

If you need to smoke on the plane of the cut soil, then it takes it evenly raised while driving. "

High maneuverability, if necessary, allow every time to start a cycle from a new place.

Nuances of exploitation

1. 4 configurations of the caterpillar aggregate DT-75 are known:
