What does the steering system consist of? What are the components of a car s steering system

The basic components of the steering system.

1) The steering control mechanism is mainly composed of steering wheel, steering shaft, steering column, etc.

2) Steering gear A mechanism that changes the rotation of the steering wheel into the swing of the steering rocker arm or the linear reciprocating motion of the rack shaft, and amplifies the steering control force. The steering gear is generally fixed on the frame or body of the car, and the steering control force will generally change the direction of transmission after passing through the steering gear.

3) Steering transmission mechanism The mechanism that transmits the force and motion output by the steering gear to the wheels (steering knuckles) and makes the left and right wheels deflect according to a certain relationship.

According to the different steering energy, the steering system can be divided into two categories: mechanical steering system and power steering system.

As far as the power steering system configured on the current car and the information I can see, it can be roughly divided into three categories, (1) one is the mechanical hydraulic power steering system; (2) one is an electro-hydraulic power steering system; (3) Another electric power steering system.

The steering system is generally composed of three parts: the steering control mechanism, the steering device and the steering mechanism. When the steering wheel is turned, the steering shaft and worm rotate with this, roll and move up and down with the worm mesh, so that the steering rocker arm swings, and pushes the straight tie rod to move back and forth. Therefore, the rotating joint is centered on the steering kingpin, which drives the deflection of one side of the front wheel, so as to achieve the purpose of controlling the steering of the vehicle.

The steering system of the vehicle is composed of three parts: steering control mechanism, steering gear, and steering transmission mechanism.

The function of the steering system is to ensure that the car can drive in the direction selected by the driver. The steering system is mainly composed of a steering control mechanism (including a steering wheel, a steering shaft, etc.), a steering gear, and a steering transmission mechanism (including a steering tie rod, a turning knuckle, a steering knuckle, a steering wheel, etc.).

The steering system is composed of three parts: steering control mechanism, steering gear and steering transmission mechanism, and the driver's physical strength is used as steering energy.

There are two types of steering systems: mechanical steering system, where the steering energy is the driver's physical strength; The steering energy of the power steering system includes the driver's physical strength and engine power, and is generally used in vehicles weighing more than 50 tons.

The requirements of the steering system are: the ability to automatically return to the center, the operation should be light and sensitive, the direction of rotation should be consistent with the change of the car's driving, the recoil force transmitted to the steering wheel should be as small as possible, and the natural vibration should not be generated in the driving state.

For the correct design of the trapezoidal mechanism of steering, it can ensure that the wheels rotate around the steering center when the car is turning and driving.

From the current point of view, the more mature technology types include worm Xiao type (WP type), worm roller type (WR type), recirculating ball type (BS type), rack and pinion type (RP type), which have been widely used in automobiles. Judging from the data, the recirculating ball steering gear accounts for about 45%, the rack and pinion steering gear accounts for about 40%, the worm roller steering gear accounts for about 10%, and other types of steering gear account for 5%.

Judging from the development trend, the steady development of the circulating ball type, especially in buses, has reached 100%.

Common faults in the steering system include direction deviation, direction swinging, heavy steering, insufficient turning, etc.

According to the advantages of power steering, power steering systems will become a trend, not only in large vehicles, because power steering systems not only improve the handling of the car, but also improve driving safety.

The function of the car steering system is to allow the driver to control the direction of the car and keep the car driving in a straight line. Steering is achieved by human action on the steering wheel and deflection of the steering wheel (usually the front wheel) at a certain angle on the road surface.

The steering system of a car is generally composed of a steering gear and a steering transmission mechanism. The steering gear is composed of the steering wheel, steering shaft, steering snail sweat, tooth fan and other main parts. The steering transmission mechanism comprises parts such as steering rocker arm, steering longitudinal tie rod, steering knuckle arm, left and right steering levitant arm and steering tie rod.

The steering gear is composed of two parts: the steering wheel column and the steering meshing mechanism. The main function of the steering wheel column is force transmission and safety protection; The function of the steering meshing mechanism is to increase the torque and transmit the steering force to the steering transmission mechanism.

The function of the steering transmission mechanism is to transmit the force transmitted from the steering meshing mechanism to the front wheels to achieve steering.

The mechanical steering system is composed of three parts: the steering control mechanism, the steering gear and the steering transmission mechanism.

The automotive steering system consists of two major mechanisms and a device, which are:

The steering system is mainly composed of a steering tube, a steering wheel, a steering shaft and a steering column. The steering system is a control mechanism used to change the direction of a vehicle. Its function is to control the direction of travel according to the driver's wishes.

Like the braking system, it is also key to the safety of the vehicle. The steering system of an automobile is an important part of the car. A series of devices used to change or maintain the direction in which a car is traveling or reversing is called an automotive steering system.

Generally speaking, the current automotive steering system is mainly divided into two categories, one is the mechanical steering system, and the other is the power steering system. Let's start by talking about mechanical steering systems.

The mechanical steering system uses the driver's physical strength as steering energy. All power transmission components of this steering system are made of machinery. At the same time, the mechanical steering system consists of three parts:

Control mechanism, steering gear and steering transmission mechanism. The mechanical steering system has accurate control, intuitive road sense, rich information feedback, mature technology, good reliability, and low average manufacturing cost. However, the disadvantage of the mechanical steering system is that the driver will feel that the steering system is heavy and the sense of operation is poor when operating the vehicle.

Another obstacle is the power steering. Power steering is a steering system that uses the driver's physical strength and engine power as steering energy. Under normal circumstances, only a small part of the energy required by the power steering system is provided by the driver, and most of the rest is provided by the power steering system.

The reliability of the power steering system is very high. At the same time, the driver does not feel too heavy on the steering wheel when maneuvering the vehicle. He will feel that the steering wheel is light.

However, power steering systems are more expensive to manufacture than mechanical steering systems.

The steering principle of the vehicle is not too difficult. In fact, the four wheels of the vehicle rotate in the same center, with the rear axle taking precedence, and the axles of the first two wheels in the same center so that the vehicle can achieve normal steering. In order for the vehicle to steer properly, the differential is mounted on the rear axle of the vehicle.

In this way, tires that are close to the center of the circle are slower, while tires that are farther away from the center of the circle are faster, so the corners can be completed smoothly.

The steering tube, steering wheel, steering shaft, transfer column, steering operation, these parts make up the steering system. Through the steering mechanism and the operating strength in it, there will be different situations of repentance.

Gears, steering shafts, steering wheels, connecting rods, hydraulic boosters, mainly controlled by the steering device. By bending and shaking the steering wheel, you can drive the other parts, and then you can change the direction of the tire embedding.

The connecting rod, steering wheel, swing arm, cantilever and only leakage spark plug are composed of these parts, which are deflected by the steering wheel when turning, and then the steering will be carried out.

The oil pump, the fuel engine, the steering wheel, the gears, the booster, these parts are composed of the gears, and when turning, they will be rotated by the gears, and then the movement will be noisy and hydraulic, and finally the deflection will occur.

1. Steering gear

A steering gear is a device used to reduce and increase the torque in the steering system, and to change the direction of rotation of the steering torque. The steering system should be reliable, portable, and easy to operate. In the event of a collision, the steering device can play a role in reducing the injury to the driver.

The power steering system mainly transmits the power of the engine to the steering system, and controls the steering wheel with both hands through the driver's stable force. When the steering system is faultless and the engine is normal, the steering control of the car is very light, it can be said that one finger can move the steering wheel, and most of the power comes from the engine-driven hydraulic steering power peder. If the power steering system fails, it can get stuck, become heavier, or even unable to move; If the engine doesn't start, the power steering system will be paralyzed.

Although the driver has a lot of strength or physical strength, he cannot take on steering tasks on his own. This requires us to regularly inspect and maintain, solve problems in a timely manner, and eliminate hidden dangers.

Second, the rocker arm

Generally not easily damaged. But the most susceptible to damage are the ball joints and pin holders. Due to long-term lack of oil or rust, it may aggravate wear and even damage, which requires us to regularly check and maintain and add grease.

Its role is to transmit the force and motion output by the steering gear to the straight rod. The upper end of the steering rocker arm is provided with a tapered hole with a fine-toothed spline, and the hole is connected with the steering rocker shaft at the output end of the steering gear through a spline. The outer end of the rocker shaft and the outer end of the bore on the upper end of the steering rocker arm are engraved with ** as an assembly mark to ensure proper assembly.

3. Steering straight tie rod

The front end of the steering stem is a ball head, and the rear end is a ball head seat. They are all vulnerable parts. Long-term use of the vehicle, long-term use in harsh conditions or long-term non-maintenance will accelerate wear and tear, causing early damage.

This requires us to inspect, maintain, and use them correctly on a regular basis. If the ball joint is loose and worn seriously, it must be stopped immediately, replaced with new parts, and then used after the collapse is restored to normal.

Fourth, the steering tie rod

The steering tie rod is composed of hollow steel pipes with positive and reverse threads at both ends. Two ball joints are mainly installed. The ball knot is mounted on the ball joint seat, locked with a nut and installed with a cotter pin.

The ball joint seat and the ball joint at both ends of the handlet are consumable parts. If there are problems such as direction sway and direction deviation during driving, stop to check whether the ball joints at both ends are loose and whether the gap is too large. Under normal circumstances, the car is mainly to go to the repair shop for regular inspection and maintenance.

This is the only way to prolong the service life, because large trucks are pulling heavy loads or even overloading them every day. If you tow the tie rod joint, you will lose your direction while driving, endangering your own safety and pedestrian safety, and injuring others and yourself. It is essential to check the oil, water and lighting system before driving; Check tire pressure and brakes for two hours on the road; After returning to the site, the chassis is mainly inspected such as steering system, drive system, etc.

Resolve and eliminate issues in a timely manner.

It is composed of a steering tube, a steering tube, a steering wheel, and a steering column, which is used to help the car turn.

The steering tube, column steering, axle steering wheel, and most of the steering devices are made up of these three big things, which can work very well.

The main components include the steering column, the steering wheel, the steering shaft, the steering gear, and the steering transmission mechanism.

Steering wheels, steering shafts, steering columns, steering gears, etc.

The steering system consists of a steering control mechanism, a steering gear, and a steering transmission mechanism, which uses the driver's physical strength as steering energy.

Now there are two kinds of steering systems: mechanical steering systems, in which the steering energy is the driver's physical strength; The steering energy of the powertrain includes the driver's physical strength and engine power, and is generally used in vehicles over 50 tons.

The requirements for the steering system include: the ability to self-righte, the operation is light and sensitive, the direction of rotation is consistent with the change of the car, the recoil transmitted to the steering wheel is as small as possible, and there is no spontaneous vibration when driving.

The well-designed trapezoidal rotation forward mechanism can ensure that the wheels rotate around the steering center when the car turns.

From the current point of view, the mature technology types include worm type (WP type), worm roller type (WR type), recirculating ball type (BS type) and rack and pinion type (RP type), which are widely used in automobiles. According to the data, the circulating ball steering gear accounts for about 45%, the rack and pinion steering gear accounts for about 40%, the worm gear steering gear accounts for about 10%, and other types of steering gear account for about 5%.

Judging from the development trend, the ball has developed steadily, especially in the use of buses, which has reached 100%.

Common faults in the steering system include direction deviation, swinging in the direction of laughter, heavy steering, understeering, etc.

Depending on the advantages of power steering, power steering systems will become a trend and will be used not only on large vehicles, because power steering systems not only improve the mobility of the vehicle, but also improve driving safety.
