Signs of a steering problem

Almost every car driver will feel any change in the operation of his car, especially with regard to the control and movement of the car as a whole. The main element responsible for control needs repair if the following signs are present:

• Jerks when turning the steering wheel;
• Turning in one direction is easier than turning in the other direction;
• Knock at the very beginning of movement from under the hood;
• The hydraulic fluid level is determined below the required mark, despite its normal level;
• Steering wheel vibration;
• Late reaction of the car to turning the steering wheel;
• Lubricant leaking from the crankcase;
• Knocking of wheels at high speed when turning the steering wheel;
• Sounds in the steering column when making a maneuver.

These are the most common signs, but not the entire list. That is why it is important to contact a service station or car service in a timely manner for diagnostics and repair work.

Causes of malfunction

The steering mechanism is a reliable unit that is difficult to malfunction after driving less than 150 - 200 thousand kilometers, but it is possible. This is due to improper operation of the car, but there are also other reasons:

• Breakage of mechanism parts due to wear;
• Poor condition of roads;
• Poor quality oils and other automotive fluids;
• Lack of periodic technical inspection.

Often the problem lies in a malfunction of the steering rack with regards to the steering shaft on which the gear is attached. To overhaul it, the service carries out diagnostics. Then, if necessary, use a special new repair kit, which includes bushings, bearings, rubber rings, seals and other spare parts. At the request of the client, the craftsmen are ready to replace the damaged part with a new contract steering rack, which will fundamentally solve the problem.

Power steering device KAMAZ 4310

KAMAZ-4310 was developed as a passable army vehicle for the army with a 6x6 wheel arrangement, which brought its own changes to the design of the power steering

in terms of its increased ability and resistance to stress.

The power cylinder is made in a single crankcase with the entire steering mechanism. The control valves are equipped with a system of reaction plungers and centering springs to create reaction force on the steering wheel when turning it at high speeds.

Another design feature is the mounting of the steering bipod. On all-wheel drive KAMAZ vehicles of the 4310 family, bolts and cotter pins were replaced with nuts with lock washers.

Types of steering

In total, there are 3 types of steering depending on the gearbox: screw

,
worm
and
rack
. The most popular and frequently performed is the rack and pinion one, which is designed for passenger cars. It has a simple design, making it sensitive to any serious impact. The worm type has good resistance to any impacts, but differs greatly in price. The screw mechanism is practically no different from the worm mechanism, but has a higher efficiency.

Poor-quality DIY steering repair can lead to complete loss of control while driving, which promises additional problems and more expensive repairs.

1.Introduction
Steering is used to change and maintain the selected direction of movement of the vehicle. The main way to change the direction of movement is to turn the front guide wheels in a horizontal plane relative to the rear wheels.

The KamAZ-5320 vehicle uses mechanical steering with a hydraulic booster. The steering mechanism with an angular gear reducer is equipped with a steering gear with working pairs of the type screw - nut with circulating balls and rack - gear sector. The steering gear ratio is 20:1.

The hydraulic booster makes driving easier and increases safety. Hydraulic booster, using engine energy to turn and hold the wheels, reduces driver fatigue, improves the vehicle's maneuverability and ensures control in difficult conditions, such as sudden tire damage.

Maintenance and repair of KAMAZ 5320 steering. Equipment and tools. Organization of the workplace.

THAT:

Car maintenance is divided into the following types:

-EO:

— designed to monitor the condition of the steering drive.

-TO-1:

– include checking the oil level in the power steering pump reservoir; if necessary, add oil to the specified level;

- Lubricate the steering rod joints using a grease nipple until fresh grease appears in the gaps.

-TO-2:

– checking the clearances in the steering rod joints and driveshaft;

– check and, if necessary, restore the free play of the steering wheel within acceptable limits;

– remove and wash the pump filter.

Removing the steering mechanism.
— Press the bipod rod ball pin out of the bipod eye.

— Unscrew the three union nuts of the heater fuel tank pipelines, disconnect the pipelines and drain the fuel from the tank and fuel lines.

— Unscrew the four nuts securing the heater fuel tank to the bracket and remove the tank.

— Unbend lock washer 4 (Fig. 1) and unscrew nut 5.

— Remove the bipod of the KamAZ-5320 steering mechanism with a puller.

— Remove the magnetic plug from the steering gear housing and drain the oil. Screw in the plug with a torque of 29-39 Nm (3-4 kg/cm).

— Disconnect the high 8 (see Fig. 1) and low 9 pressure pipelines from the steering mechanism and drain the remaining oil in the pipelines.

— Unscrew the nut of the bolt securing the lower propeller shaft fork, knock out the bolt and disconnect the shaft from the steering mechanism by lifting the fork up.

— Remove the four bolts securing the steering gear housing to the front spring bracket and remove the steering gear.

— Drain the remaining oil by turning the steering mechanism of the KamAZ-5320 with the valve down and turning the shaft of the drive gear of the angular gearbox 2-3 times from one extreme position to the other.
