What is the main composition of a mechanical steering system?

Mechanical, hydraulic power steering.

The mechanical hydraulic power assist system mainly includes two parts: rack and pinion steering structure and hydraulic system (hydraulic booster pump, hydraulic cylinder, piston, etc.). The working principle is to provide oil pressure to push the piston through a hydraulic pump (driven by the engine belt), and then generate auxiliary force to push the steering lever to assist the wheel steering.

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 steering system is used to change or maintain the direction in which the car is moving or reversing.

The function of the steering system is to control the direction of the car according to the driver's wishes. The automobile steering system is very important to the driving safety of the car, so the parts of the automobile steering system are called security parts. The steering system and the braking system are two systems that must be paid attention to in automobile safety.

As far as wheeled vehicles are concerned, the method of realizing automobile steering is that the driver deflects the wheels on the automobile steering axle (generally the front axle) at a certain angle relative to the longitudinal axis of the automobile through a set of special mechanisms. When the car is driving in a straight line, the steering wheel will often be affected by the lateral interference force of the road surface and automatically deflect and change the direction of travel.

The steering system is composed of steering wheel, steering shaft, steering intermediate shaft, steering oil pipe, steering oil pump, steering oil tank, steering knuckle arm, steering tie rod, steering rocker arm, integral steering gear, steering straight tie rod, steering shock absorber, etc.

There are various structural forms of automobile steering system, but they all include three basic components: steering control mechanism, steering gear and steering transmission mechanism.

The function of the steering control mechanism is to transmit the driving force of the driver to turn the steering wheel to the steering gear. It is mainly composed of steering wheel, steering shaft, steering column, steering universal joint, etc.

The steering gear is 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 transmission mechanism is a mechanism that transmits the force and motion output by the steering gear to the wheels (steering knuckles) and deflects the left and right wheels according to a certain relationship. The steering transmission mechanism is composed of a steering straight tie rod, a steering knuckle arm, a steering trapezoidal arm, a steering cross tie rod, etc.

Answer: The function of the steering system is to ensure that the car can change the driving direction as needed when driving.

The mechanical steering system is generally composed of a steering control mechanism, a steering gear and a steering transmission mechanism.

The steering control mechanism is composed of a steering wheel, a steering shaft, a steering universal joint, a steering transmission shaft and other components; The steering transmission mechanism is composed of steering rocker arm, steering straight tie rod, steering knuckle arm, left and right steering trapezoidal arm and steering cross tie rod and other parts.

Mechanical turning. What is the role of the mechanical steering systemThe role of the mechanical rotation system is that the bearing drives the rotor.

The mechanical steering system consists of: rack and pinion steering structure and hydraulic system.

Hydraulic booster pumps, hydraulic cylinders.

piston, etc.).

Modern mid-to-high-end cars and heavy-duty vehicles generally adopt power steering systems, which not only greatly improves the lightness of car handling, but also improves the driving safety of cars. The power steering system is formed by adding a set of steering afterburner devices that rely on the power output of the engine on the basis of the mechanical steering system. Cars generally use a pinion strip power steering mechanism.

This kind of steering gear has a simple structure, high control sensitivity, light steering control, and because the steering gear is completely closed, it does not need to be checked and adjusted at ordinary times.

The maintenance of the power steering system is mainly to regularly check the level of the power steering fluid in the reservoir.

When in the hot state (about 66, it feels hot when you touch it), the liquid level height must be between the hot (hot) and cold (cold) marks. If it is in the cold state (about 21), the liquid level height must be between the Add (plus) and CLOD (cold) marks. If the liquid level does not meet the requirements, the DEXRON2 power steering fluid (hydraulic transmission oil) must be filled

The mechanical steering system uses the driver's physical strength as the steering energy, in which all the force transmission parts are mechanical, mainly composed of three parts: steering control mechanism, steering gear and steering transmission mechanism.

Figure 23-1 shows the mechanical steering system of a passenger car. When the car turns, the driver exerts a steering moment to the steering wheel 1. This torque is transmitted to the steering gear 6 by the steering shaft 3 and the flexible coupling 4, and then is transmitted to the steering knuckle 14 that is fixed on both sides by the left and right cross tie rod 119

On the left and right knuckle arm 13 (the right side knuckle and the knuckle arm are not drawn), the steering knuckle and the steering wheel it supports are deflected at a certain angle around the kingpin axis, and the steering is realized.

A series of parts from the steering wheel to the steering gear belong to the steering control mechanism. From the steering gear to the steering knuckle, a series of parts (excluding the steering knuckle) belong to the steering transmission mechanism.

At present, many models produced at home and abroad adopt universal transmission devices (including steering universal joints and steering transmission shafts) in the steering control mechanism, as shown in Figure 23-2. As long as the geometric parameters of the steering universal transmission device are appropriately changed, the general arrangement requirements of various variants can be met, which is conducive to the generalization and serialization of components such as steering wheel and steering gear. Even in the case of the coaxial line between the steering wheel and the steering gear, the universal transmission device can be used to compensate for the actual non-overlap of the two axes due to the installation error of the components on the car and the deformation of the mounting substrate (cab, frame).

The steering wheel rotates to make the steering machine worm rotate, the vortex rod and the worm gear bite (there is also the circulating ball bite) turbine shaft drives the direction machine rocker arm to swing back and forth, the direction machine rocker arm is connected with the vertical tie rod by the ball head pin, the other end of the vertical tie rod is connected with the left front wheel axle head rocker arm, the shaft head rocker arm is connected with the front axle through the vertical pin (kingpin), the rocker arm swings back and forth to make the wheel axle head (along the kingpin) turn left and right, and the left front wheel is connected with the right wheel through the cross tie rod, so that the left and right front wheels can be turned at the same time by rotating the steering wheel.

There are three main parts of the <>: steering control mechanism (steering wheel, steering shaft), steering gear and steering transmission old mechanism (yellow tie rod, knuckle arm, knuckle, etc.).

Cars are already an essential tool for everyone to travel. Of course, automotive knowledge is essential. In order to facilitate everyone to understand this knowledge, today Bian Xiao will introduce to you the question of what the mechanical steering system is composed of.

If you are interested, you can learn about it, which may be helpful to you.

The mechanical steering system consists of two parts: rack and pinion steering structure and hydraulic system (hydraulic booster pump, hydraulic cylinder, piston, etc.). Power steering systems are widely used in modern cars and heavy-duty vehicles, which not only greatly improve the mobility of the vehicle, but also improve the driving safety factor.

The power steering system is formed by adding a set of steering boosters that rely on the output power of the engine on the basis of the mechanical steering system. The gear lever power steering mechanism is widely used in automobiles. This kind of steering gear has a simple structure, high control sensitivity, light steering, and because the steering gear is fully enclosed, it does not need to be checked and adjusted in ordinary times.

The key to power steering system maintenance is to regularly maintain the level of power steering fluid in the fluid reservoir. When it is hot (around 66, it is hot when touched by hand), the liquid level must be between the hot and cold signs. If it is cold (about 21), the level must be between the ADD and CLOD marks.

If the fluid level does not meet the requirements, the dexron2 power steering fluid (hydraulic transmission oil) must be filled.

Cars have become an indispensable tool for everyone to get around. When using a car, it is very necessary to have some knowledge of the car. In order to help you better understand the knowledge of automobiles, today I will introduce to you the question of what parts of the mechanical steering system are made up.

If you are interested, you can find out about it, which will help you. The mechanical steering system consists of two parts: rack and pinion steering structure and hydraulic system, which includes hydraulic booster pump, hydraulic cylinder, piston, etc.

This steering structure is widely used in modern cars and heavy-duty vehicles, which not only greatly improves the mobility of the vehicle, but also improves the driving safety factor. The power steering system is formed by adding a set of steering boosters that rely on the engine to output the power on the basis of the mechanical steering system. In automobiles, the gear lever power steering mechanism is widely used or stared.

This kind of steering gear has a simple structure, high operation sensitivity, light steering, and the steering gear is fully enclosed, and it does not need to be checked and adjusted at ordinary times. Maintenance of the power steering system is critical, and the level of the steering fluid in the fluid reservoir needs to be maintained regularly. When the temperature is normal (about 66, feel hot when touched by hand), the liquid level should be kept between the hot and cold markers; If it is in a low temperature environment (approx. 21), the liquid level must be between the ADD and CLOD marks.

If the fluid level does not meet the requirements, it needs to be supplemented with dexron2 power steering fluid (hydraulic transmission oil).
