What is the purpose of a direction machine? What do you know about the role of the car steering mach

The steering machine, also known as the steering machine, is the most important component in the steering system of the automobile, and its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the transmission direction of the force.

The steering machine of the car is also called the steering gear or steering machine. As the name suggests, it is an important part of the steering system of the car, and its function is to increase the force transmitted from the steering wheel to the steering mechanism, thereby helping to change the direction of the car. The structure of this component may seem simple, but it has a significant impact on the braking system of the entire vehicle.

Because of this, many manufacturers of automobiles have sealed the steering machine, and ordinary people can't disassemble the steering machine.

So generally speaking, if the steering machine is damaged, we can only replace the assembly, of course, there are many types of steering machines, sometimes we don't have to replace the assembly, but also can put it in the repair shop for maintenance. Generally speaking, the steering machine of the car can be divided into four categories: mechanical-hydraulic or mechanical, or electro-hydraulic and electro-hydraulic. Today, when private cars are more popular, the steering machine we see more commonly is the mechanical hydraulic power assist type, which uses the engine to drive the steering pump to rotate, thereby changing the direction.

Hydraulically assisted steering systems specifically require an engine to provide power. But this kind of steering machine also has its own problems, there is a low speed and heavier, which affects the feel.

Today's high-end cars mostly use electro-hydraulic type, and the shortcomings of this kind of steering machine are particularly few. And it saves fuel consumption and feels better, but of course, it also costs the highest.

At present, several problems that are prone to occur in the steering machine are oil leakage, abnormal noise, or when playing the steering wheel, it feels particularly heavy. In view of these problems, we must pay special attention, do not panic in case of trouble, and troubleshoot first. Generally speaking, when there is an abnormal sound, it may be that the connection between the steering wheel and the steering column is loose, and the reason why the steering feels heavy may be because the steering machine category is different, we are not used to it, or it may be that the related parts are rusty and deformed.

That's all I know.

The steering machine, also known as the steering gear, uses the engine or motor as the power to exert auxiliary force on the steering system to help the driver steer the tires more safely and conveniently. It is also the most important part of a car for steering functions! It is also an important guarantee for the safety of car driving!

It must have played an important role, and it also played a role in controlling the direction, after all, it is the steering machine of the car. Without this steering machine, it is very likely that the car would not be able to function properly.

I know. The car's steering machine can make the sense of direction better, and at the same time, it is more stable to drive when on the highway, and there will be no unstable direction.

It has the effect of changing the direction of the car. It can make the car perform better, and we can go where we want to go.

The orientation machine is also called the steering gear, and the steering function is the most important part of the car! It is also an important guarantee for the safety of the car! Its internal structure is sophisticated!

The steering system configured on the car can be roughly divided into three categories: mechanical hydraulic power steering system; electro-hydraulic power steering; Another electric power steering system. Mechanical-hydraulic power steering.

The mechanical hydraulic power steering system is generally composed of hydraulic pumps, oil pipes, pressure and flow control valve bodies, V-shaped transmission belts, oil storage tanks and other components. This system works regardless of whether the car turns or not, and when the large steering speed is low, it <>

Hydraulic pumps need to output more power to get more power, so resources are wasted to a certain extent. It can be recalled that when driving such a car, especially when turning at low speeds, the direction is heavier, and the engine costs more effort. And because the pressure of the hydraulic pump is high, it is easy to damage the booster system.

In addition, the mechanical hydraulic power steering system consists of a hydraulic pump, a pipeline, and a cylinder. In order to maintain the pressure, the system is always in working condition, and the high energy consumption is one of the reasons for the consumption of resources. In general, economy cars use more mechanical hydraulic booster systems.

Electro-hydraulic power steering system, main components: oil storage tank, power steering control unit, electric pump, steering gear, power steering sensor, etc. The power steering control unit and electric pump are a monolithic structure.

Working principle: The electro-hydraulic power steering system overcomes the shortcomings of the traditional hydraulic power steering system. The hydraulic pump it uses is no longer directly driven by the engine belt, but an electric pump, and all its working conditions are calculated by the electronic control unit according to the signals of the vehicle's driving speed and steering angle.

To put it simply, when low-speed and large-scale steering, the electronic control unit drives the electro-hydraulic pump to run at high speed, outputs high power, and the driver steers labor-saving; When the car is driving at high speed, the hydraulic control unit drives the electro-hydraulic pump to run at low speed, which can save a part of the engine power without affecting the need for high-speed steering. Electric power steering. The full name in English is Electronic Power Steering, abbreviated as EPS, which uses the power generated by the electric motor to assist the driver in power steering.

The composition of the EPS, although the structural composition of different cars is different, is generally similar.

I know that the steering machine of the car is very important, this is an important part of the car, this thing is also called the steering gear, which can protect the safety of the car, which is roughly divided into three categories, mechanical pressure, electro-hydraulic power, and electric power assist.

I don't know much, this is a very important thing in the car, it can be better steering, it is the key thing to connect the steering wheel and the front wheel, it is very important.

It reduces the steering wheel control force and ensures that the car can steer correctly according to the driver's will. Reduce the steering wheel steering force and ensure the angle at which the steering wheel turns; Ensure that the car can steer correctly at the driver's will, proportional to the angle at which the tires turn.

It can better adjust the direction, can better drive, is conducive to the operation of the steering wheel, avoids danger, and can better grasp the driving direction of the car.

The car is now a more important means of transportation, so the more important thing in the car should be the air conditioning of the car, then in people's impression, the summer is the busiest state of the air conditioner, there will be such and such problems, the most important thing about the car should be the usual maintenance, mechanical steering is very important, let's find out.

1.The clearance of the steering machine in use will gradually increase, if the left and right empty strokes of the steering wheel exceed 15 degrees, the steering machine must be checked, such as the rack and pinion are seriously worn, the steering machine assembly must be replaced; If there is no abnormal wear and tear of the cracked fruit, but the gap is too large, it can be adjusted. When adjusting, it is necessary to go to the service station to be carried out by trained professionals, and after adjustment, it is necessary to ensure that the steering wheel can hit the left and right to the limit position, and the force is uniform and the rotation is flexible.

2.Always check the state of the protective sleeves on both sides of the steering machine and the protective sleeves connected to the universal cross shaft on the upper part of the steering machine. Breakage of the sheath is the most important factor that causes early wear and damage to the steering machine.

After the sheath is damaged, water and dust and sand will enter the steering machine through the damaged place, destroying the grease oil film of the gear rack and pinion, resulting in rust and abnormal wear and tear inside the steering machine. Therefore, check the status of the dustproof sheath at least once a month, if the sheath is found to be closed and damaged, it must be replaced immediately, and the steering machine should be comprehensively inspected and maintained before replacement.

What are the commonly used steering machines for automobiles Audi, Mercedes-Benz, BMW, Porsche, Ferrari, Lamborghini, Maserati, Cadillac, Volkswagen. Roewe.

The steering machine commonly used in automobiles is the left direction machine.

The working principle of the steering machine: 1. The steering gear, commonly known as the steering machine, is the most important part of the car for the steering function, and it is also an important guarantee for the safety of the car; 2. It is one of the most common steering gears. Its basic structure is a pair of pinions and racks that mesh with each other.

When the steering shaft drives the pinion to rotate, the rack moves in a straight line. Sometimes, relying on the reputation of the branch to clear the rack to directly drive the horizontal pull of the fierce rod, you can make the steering wheel turn; 3. When the steering screw rotates, the force is transmitted to the nut through the steel ball, the nut moves along the axis, the nut is meshed with the sector gear, and the linear motion becomes a rotary motion again, so that the connecting rod arm shakes, and the connecting rod arm makes the linkage pull rod and the transverse tie rod do linear motion, and the wheel steering is commonly known as the steering machine.

There are mainly the following aspects to pay attention to in the use of the direction machine:

1. Regularly inspect the steering machine of the car, and check the state of the protective sleeve on both sides of the upper part of the fire direction machine and the connection protective sleeve of the universal cross shaft. Breakage of the sheath can lead to premature wear and damage to the steering machine of the car. If the sheath is damaged, water, dust and sand will flow into the damaged area and cause it to flow into the steering machine, resulting in the wear and tear of the rack and pinion inside, resulting in other problems such as withering, corrosion, and wear inside the steering machine.

2. During maintenance, the tightness of the steering pump belt should be checked to see if there is a break, if there is a timely replacement, the tightness should be pressed by the finger about 1cm;

3. Regularly check whether there is oil leakage in the pipe joints of the hydraulic system, and the hydraulic oil pipe should try to avoid friction with other components to prevent damage to air intake, and at the same time, the hydraulic hose should be replaced regularly to prevent the hose from peeling and blocking the pipeline;

4. When maintaining the steering gear, it should be installed and adjusted properly, especially the assembly between the worm gear and worm, the steel ball must be installed enough, and the steel slide rail is not allowed to be deformed, and the hydraulic oil valve and piston cavity wall should be cleaned, and the high-quality, model matching oil seal should be selected to prevent the leakage of hydraulic oil;

5. When steering, do not "kill" the direction, especially when turning in situ, leave a certain margin to ensure that the hydraulic steering system is in normal working condition.

6. Can not be in the equipment backward, technical level of the maintenance shop for the maintenance and maintenance of the steering machine, once the direction machine is not properly adjusted, it will lead to the phenomenon of stuck, the road is easy to occur dangerous.
