Motor grader

The utility model relates to road-building engineering, in particular, to devices for excavation - profiling and public works in the repair and maintenance of roads, winter and summer maintenance of public utilities.

The well-known im 80 idro grader from Sicom Italy, consisting of a biaxial traction module with balancers, a spinal half frame connected to the traction module by a vertical hinge, a front axle, a grader working body, a front blade, a rear cultivator, a hydraulic system of working bodies and electrical equipment (Safer Sicom Italy Avenue from the World Fair Bauma - 2001, Munich, Germany).

The main disadvantages of the Sicom grader are:

-Lack of parallelogram suspension of the front blade;

-Lack of wings of the front wheels;

-the lack of a turntable grader working body;

- the lack of a mechanism for changing the angle of cutting of a grader blade. The purpose of the claimed utility model is to increase efficiency.

process.

To this end :

A.1 In the grader, we support the articulated frame, the working bodies in the base and in front, the cab, the power unit, the transmission, the front axle, the hydraulic system of the working bodies and electrical equipment, the power unit is based on the D-243 MMZ or D- engine 75 RMZ, or 4V 3.9C KAMMINS, transmission - based on the gearbox and rear axle of the Belarus MTZ-80 tractor, moreover, the power unit, gearbox and rear axle are mounted on the supports in the submotor frame, secured with special bolts and fingers, the body is attached to the engine flange clutch gearbox independent about the hydraulic pump drive, and the brakes are installed on the clutch shaft, the shoe of which is connected to the clutch release lever, while the cardan shaft is attached to the brake flange, which is attached to the MTZ-80 tractor gearbox input flange at the other end, and between the gearbox and the rear axle a vertical intermediate gear is located, moreover, the gearbox is installed above the rear axle with a small gap, the rear axle is fixed between 2001133850

do balancers, and the front axle is installed in the opening of the head bracket of the spinal half frame and is fixed with a cylindrical finger.

p. 2 In the grader according to claim 1, a clutch housing is attached to the engine flange, which is integral with the gear housing of the independent hydraulic pump drive, brake, reduction gear and independent power take-off shaft of the MTZ-80 tractor, located in one housing block, which is on the other side attached to the gearbox of the MTZ-80 tractor.

Figure 2 is a General view of the grader, a top view.

Fig. 3 is a prospectus of the Sicom motor grader.

The basis of the proposed utility model is the articulated frame 1, on which all the nodes of the machine are mounted. A front blade 2 is attached to the front of the spinal half-frame on a parallelogram suspension, and a front steered axle 3 with wheels closed by wings is suspended with a possibility of lateral swinging. The arm 4 of the attachment of the lifting and offset hydraulic cylinders to the side of the traction frame covers the ridge half frame from three sides, without covering the upper surface for a better view. The hydraulic cylinder 5 lifting the front blade is attached to the removable plate by the liner liner.

In the base between the axles of the machine, the main grader working member 6 is suspended, consisting of a T-shaped traction frame, an axleless turntable, symmetrically arranged hydraulic cylinders for turning the blade in plan, a centrally located hydraulic cylinder for changing the blade cutting angle, fixed with pins to the frame of the blade, and the stock a hole to the turntable, the hydraulic cylinder for removing the blade to one side or the other and the blade blade with a frame. When the cutting angle is changed, the blade rotates with the frame.

The front of the machine is supplemented by blocks of headlights with a protective fence and lighting devices installed on the transverse cr01 Щ | -ane, electrical equipment 7 of the grader.

Changing the position of the front frame relative to the rear in the horizontal plane is carried out by two hydraulic cylinders. Lock semi-frames produced by hard traction. The lateral surfaces of the spinal half-frame are closed by false panels, under which the pipelines of the hydraulic system 8 of the grader are placed.

A traction module is mounted on the rear submotor frame, including a power unit 9 with radiators and control mechanisms, a hood 10, a cab 11 with microclimate systems and car controls, a transmission consisting of a clutch 12, a brake 13, a cardan shaft 14, a gearbox 15, the intermediate gear 16, the rear axle 17, the main brakes 18, the emergency brakes 19 and the parking brake 20. The rear axle is connected to the side balancers 21 based on the wheels 22 closed by the wings 23. Battery boxes 24 and the steps 25 are located on the traction module on the left and right.

Kalami side view. The upper part of the front wall of the cabin in the form of a windshield is made opening.

The front steered axle 3 consists of a beam, hubs, wheels, steering trapezoid with hydraulic control cylinders and a tilt mechanism for the wheels.

The fuel tank 26 is installed between the cab and the hood of the power unit and at the same time is a reflector and a noise absorber from the operation of the power unit and other systems of the machine, reducing the sound pressure level in the cabin.

Two identical tanks of the hydraulic system of the working bodies are located symmetrically on the rear of the submotor frame. A block of radiators is installed between the tanks, which are closed behind the mesh grill to ensure normal ventilation.

Ventilation grills on the hood sides provide normal ventilation of the power unit.

The taillights 27 are mounted in boxes and mounted on brackets on the sides of the hood. Under the headlights, the lights are of the brake lights, direction indicators and dimensions.

Inside the under-engine half frame, under the block of radiators, the pneumatic system 28 for tire inflation is placed. For these purposes, the power unit has a compressor.

The grader can be equipped with interchangeable and additional working bodies of both active and passive action. Ahead you can hang a plow or a rotary snow blower, a bucket loader, an ice rink, a cylindrical brush, a scarifier.
