The most modern machines are equipped with imported engines from the American brand Cummins. The Cummins 6ВТ5.9-С135 model produces a maximum power of 100 hp. The Cummins 6VTA-C165 model operates at a maximum power of 120 hp. American engines are reliable and do not require serious repairs over a long period of time. On the other hand, Russian power units are cheaper to maintain, and spare parts for the GS 14.02 motor grader motors are available in any region.

Fuel consumption

This model of the device is equipped with a large fuel tank of 490 liters. Various motor grader configurations use their own engines, so fuel consumption depends on their power. Most often, engines with a consumption of 220 -230 g/kWh are used for these purposes.

Transmission

Modern GS 14.02 graders are equipped with automatic gearboxes of the German ZF brand. As standard with the domestic power unit, the car comes with a manual transmission. GS 14.02 can move with six forward and two reverse speeds. In this case, the speed range is 4.1-34.2 km/h.

The manufacturer used a 1x2x3 wheel arrangement in the grader's chassis. Base models are equipped with 14.00-20 tires. The gearbox is complemented by a NAF tandem bogie and a No-Spin differential. The service braking system is represented by disc brakes controlled by a pedal. The device uses a dual-circuit brake system that provides equal force on all wheels of the motor grader. To increase reliability, the brake mechanism is equipped with a backup power source.

Hydraulic system

The GS 14.02 hydraulic system uses a constant volume pump with an additional system for unloading the working unit when the control handle is in the neutral position. The functioning of the system is ensured by six manual hydraulic valves, with the help of which the working bodies are controlled. Four electric hydraulic valves are used to perform related operations.

Device

A machine of this class is used for road surface planning and profiling. Additionally, it is used to create embankments from gravel, various types of soil and crushed stone by leveling and moving them. In winter, it is allowed to use the GS-14.02 motor grader to clear road transport routes from precipitation and formed ice. This is possible due to the wide range of operating temperatures and adaptation to work in tropical and temperate latitudes.

A wide grip on the grader blade is achieved through the use of an articulated frame and rotary grader and bulldozer blades. This design also allows the machine to be used for profiling in the opposite direction of movement due to the reverse gear. The blade is located directly between the front and rear axles and is fully rotatable.

The design feature of the GS-14.02 motor grader is that it is equipped with removable equipment. Therefore, its bulldozer blade can be replaced with a ripper-pick, and it, in turn, can be replaced with a ripper-scarifier. The power of the equipment directly depends on the engine used, but due to the fact that there are several design options, each modification should be considered separately, based on the technical characteristics.

The GS-14.02 motor grader is adapted for work in high mountain areas. This is largely possible thanks to the transmission used. It's made in Germany here. The brake system is dual-circuit hydraulic with a backup power source. It is complemented by a parking brake with gear lock. The hydraulics are supplied with a constant volume pump. It includes 6 hydraulic boosters for the main equipment and four electrical modules for additional equipment, as well as hydraulic locks for the circuits.

The operator's work is facilitated by the automatic blade control system. For this purpose, the design provides a number of sensors and balancers, also containing sensors.

dimensions

• length - 8820 mm;
• width - 2500 mm;
• cabin roof height - 3475 mm;
• operating weight - 13,500 kg.

Controls

The steering operates on the front pair of swivel wheels through a drive consisting of two hydraulic cylinders. There is no mechanical connection between the wheels and the steering column.

The use of the drive, the tilt of the steering wheels and the bending of the frame provides the unit with a turning radius of 7.8 m.

Shoe brakes with hydraulic drive are installed on the wheels of the rear axle. The disc-type parking brake acts on the drive gear shaft of the central gearbox. Cab mounting dampers, heating and ventilation devices, and spring seat suspension create comfortable conditions for the operator.

The cabin equipment is well thought out, and the interior ergonomics are modern. Glazing with a minimum of closed areas, headlights and mirrors provide visibility of the working area and visual control of the motor grader components.

The cabin, reinforced with steel inserts, protects the operator in emergency situations. The turntable for mounting the grader blade is secured in three places by clamping devices. It is controlled by a pair of hydraulic cylinders with valves configured to relieve shock loads.

Grader GS 14 02 front hub diagram

Motor grader GS-14.02. Front axle

The front axle (Figure 13) is attached to the motor grader frame using axle 36. On the axle, the front axle can freely rotate in a plane perpendicular to the axis of the machine, which ensures constant contact of all wheels with the ground and ensures the leveling ability of the motor grader. The swing of the front axle is limited by stops on the frame bracket.

At the ends of the beam, brackets 3 are installed in the forks with axles on which the wheel hubs are mounted. The wheel axles are equipped with levers connected by rod 44.

Fenders (mud flaps) are installed on the pins that secure the wheel axles, which turn and tilt along with the wheels.

The rotation of the wheels is carried out by hydraulic cylinders 6, the sleeves of which are fixed to the axle 36 by forks, and the rods are connected by crosses 34 with levers.

The wheels are tilted using a hydraulic cylinder 5, one end of which is fixed by a pin to the beam 43, and the other to the left bracket 3. The brackets are connected to each other by a rod 4. When the rod moves, the left bracket rotates around the axis and turns the right bracket through the rod, and the brackets through The hub axles tilt the wheels.

With inclined wheels, the turning radius of the motor grader decreases and the stability against skidding increases under heavy loads on the blade.

Adjustment of the front wheel hub bearings is described in the “Wheels” section.

To make it easier to turn the wheels, they are installed with camber. This is achieved by the design of the hub axles and additional adjustments are not required during operation.

To protect the tires from excessive wear, the front wheels are installed with some toe-in, which is adjusted by rod 44. In this case, the distance between the centers of the wheels in front should be 8...9 mm less than the same distance behind the wheels.

A

motor grader GS-14.02. The procedure for carrying out individual repair operations of the brake system of a motor grader with a hydraulic pedal and a pneumatic-hydraulic accumulator

Before starting to repair the brake system, it is necessary to perform several brakes in the parking lot with the engine running and make sure that the brake pedal completely returns to its original position, and that there is a gap between the pedal and the pressure rod, which is necessary to completely release the car. If after this there is a need for repairs, turn off the engine and perform about 20 pedal braking until the fluid in the hydraulic accumulators is completely consumed, otherwise the system will be under pressure and disassembling it is unsafe.

If there is increased oil leakage through the brake pedal:

— Depress the brake pedal completely and hold it in this position. If the characteristic clicks have stopped or their frequency has noticeably decreased, then the cause of the malfunction is the pedal and its repair or replacement is required;

— an additional sign of increased oil leakage in the brake pedal is the rapid lighting of the red warning lamp for emergency oil pressure in the accumulator after stopping the engine;

If there is insufficient or excessive nitrogen pressure in the accumulator:

Start the engine and stop it after 1...2 minutes. Periodically pressing the brake pedal, count the number of braking times in each circuit (using the green indicator lamps on the remote control).

A circuit in which there is not enough nitrogen has an increased number of brakes - usually more than 20 with reduced braking efficiency.

A circuit in which there is an excess of nitrogen has a reduced number of brakes - usually less than 10. The normal number of brakes is from 10 to 20, but not less than 6 after the red warning lamp comes on.

To check the nitrogen pressure in the hydraulic accumulator, remove the plug at the top of the hydraulic accumulator and install a pressure gauge on a special fitting instead of the plug (a drawing of the fitting is available in the Operating Manual for the hydraulic accumulator). Nitrogen pressure should be 50 - 55 kgf/cm2. If necessary, recharge the hydraulic accumulators with nitrogen, install the plug, check the tightness of the charging valve and the absence of nitrogen leaks.
