The assembly is a 3-element liquid-cooled torque converter and a planetary type gearbox (ranges 3F and 3R), complemented by a torque converter lock-up clutch and hydraulic drive. The technique also has a reduced third gear.

The hydraulic system consists of a powerful piston type hydraulic pump with a capacity of 248 l / min and spool valves installed next to the hydraulic tank. The function of seals in the hydraulic system is played by flat O-rings that prevent the flow of hoses with hydraulic fluid. The basic implement tilt cylinder piping is housed in the push bar body for maximum safety and no damage.

In addition to the standard dozer blade and single-shank ripper, the bulldozer can be equipped with fixed tilt blade, tilt blade, straight blade, hemispherical blade, manual angle straight blade, multi-shank parallelogram ripper and Komatsu rippers.

The basic cab of the bulldozer has a ROPS safety system made using 3D modeling. The cabin is characterized by increased tightness and strength, and the operator in the cabin feels great under any conditions. Dust and noise from the working platform do not penetrate inside, and the temperature is always maintained at the same level. The special design without external grille and racks improves visibility of the workspace. Due to the installation of a damper at the attachment points of the cabin, dynamic effects are noticeably reduced. Even working on a non-uniform surface leads to minimal vibrations, the spring mechanism perfectly absorbs vibration.

To control the parameters of the machine, a large LCD screen is installed in the cabin, where information about the state of the bulldozer is displayed in different languages. Such information content ensures maximum accuracy and process safety. The cabin also has switches that can be operated intuitively.

The control of the main processes is carried out by means of a joystick (speed and direction, operating mode, control of the working body, gearbox indicators). Hydrostatic steering makes turns easy.

The Komatsu D65EX needs regular maintenance and inspection. Convenient access points make this process easier. In the event of malfunctions, information is sent to the screen located in the operator's cabin. To attract the attention of the driver, a lamp and a buzzer are used. Access to the engine compartment is provided by large doors that open using gas-filled stops. The block design of the power transmission allows you to replace elements in the shortest possible time.

Engine

The unit is equipped with a four-stroke diesel engine with direct injection, water-cooled. 6D125E with a speed of 1950 rpm on the flywheel, a power of 135 kW with a flow rate of 180 g / kW per hour is considered one of the economical engines of the traction class 10-12, which allows it to develop a maximum torque of 799 Nm at 1100 rpm. Equipped with forced lubrication mechanism. Low noise level and compliance with all modern environmental requirement allows it to be used in urban environments.

Transmission

The Komatsu d65e-12 bulldozer is equipped with Komatsu's own TORQFLOW transmission. It is a three-element, forced liquid-cooled, single-stage, single-phase torque converter. Hydraulically driven planetary gearbox with multi-plate clutch is flawless manual gearboxes. To increase the resource, the box is forcibly lubricated, removing excess heat. The box allows you to work with three forward and three reverse gears. Management is made by joysticks. To ensure safety, the unit is equipped with locking levers.

The onboard gearbox is made in the form of planetary and spur gears, minimizing the possibility of transferring impacts to the power transmission. Using the experience of previous years, the gear wheel was segmented, which makes it easy to change damaged segments in the field.

The bulldozer is controlled by a joystick. Light movements in the desired direction allow you to effectively control a 16 ton machine. This is achieved through the advantages of using hydraulic clutch and braking systems. The minimum turning radius for impressive dimensions is only 3.2 m.

Chassis

The undercarriage of the Komatsu d65e-12 bulldozer consists of a pair of caterpillar belts, suspension, support rollers, road wheels mounted on the track frame. Suspension swinging with balancing bar, with rolling axles mounted in front. The design is equipped on each side with support rollers, between them there are 7 support rollers on each side. The caterpillar consists of 39 links. Link connections are made according to unique technology preventing the ingress of abrasive materials into the joints.

The frame with a flat bottom is designed in such a way that when working on viscous soils, it prevents the build-up of dirt under the frame. The brake system is represented by multi-disc brakes operating in an oil bath.

Cabin. Bulldozer control

When working on the Komatsu d65e-12 bulldozer, the operator is unloaded as much as possible: a comfortable work chair, a ventilation and air conditioning system, increased visibility of the control cab - all this makes the operator's work as easy as possible.

The bulldozer is easily controlled with a joystick specially designed by Kamatsu. The joystick clearly responds to the actions of the operator and with its help the bulldozer is able to easily maneuver on the working surface.

One of the advantages of the design of this model is good shock absorption and low noise level. The control cabin is easily adjusted to the operator and contains active protection against dust penetration into the interior of the cabin. base model The unit can be equipped with a reinforced cab if additional operator protection is required.

Blade control is almost invisible to the operator at different speeds and material quantities, which allows for accurate work with the material. This effect was obtained due to the use of CLSS technology in the production of the hydraulic system of the blade. This is expressed in the smooth compensation of direct impacts of the material into the dump.

Convenient and well-designed electronic troubleshooting system makes troubleshooting and troubleshooting easy. Which in turn allows you to control the resource of the bulldozer as a whole and its parts.
