What is the composition of the chassis of the car? What are the components of a car chassis?

The automobile chassis is a system, not just a certain component, it is composed of four parts: transmission system, driving system, steering system and brake system. The role of the chassis is to support and install the assembly of the automobile engine and its various components. And accept the power of the engine, so that the car produces movement, to ensure normal driving.

1. Transmission system.

The transmission system structure of the automobile is very complex, it mainly refers to the power transmission device between the engine and the driving wheels, which is composed of clutch, universal rotation device, drive axle and other components. The main function of the transmission system is to ensure the necessary traction, vehicle speed, and coordinated changes between vehicle speeds under various conditions of vehicle driving. That is to say, it can ensure that the car can reverse, and the left and right drive wheels can adapt to the differential requirements.

Second, the driving system.

The driving system of a car is easier to understand, it is composed of the frame, wheels, and suspension and other components. Generally speaking, the handling of the vehicle is determined by the driving system of the car. The main function is to make the torque from the drive train become the driving torque of the car through the adhesion between the wheel and the road surface.

And it supports the total mass of the car, which can moderate the impact, reduce the vibration, and ensure the driving stability of the car.

3. Steering system.

When we think of the steering of a car, we think of the steering wheel. In fact, the steering system of a car mainly refers to a series of devices used to change or maintain the direction of the car moving or reversing. For example, the steering control mechanism, steering gear, steering transmission mechanism, etc., are all part of the steering system.

Its main function is to control the direction of the vehicle according to the driver's wishes, which is very important for the driving safety of the vehicle.

Fourth, the braking system.

In order to ensure the safe driving of automobiles, increase the average driving speed of automobiles, and improve transportation productivity, special braking mechanisms are provided on various automobiles. Such a series of specialized devices is called a braking system. It refers to a series of specialized devices on a car that generate braking power.

For example, brake pads, brake pedals, etc. The main function is to enable the moving car to slow down, stop, and maintain a steady speed when going downhill.

The benefits of a low car chassis.

1. Reducing the chassis of the car can increase the downward pressure of the car body, thereby improving the grip performance (according to the friction formula, the greater the pressure, the greater the friction). When the chassis is lower, downward aerodynamic pressure can be provided to the body at high speeds. Because according to Bernoulli's principle, a narrow channel will increase the air circulation velocity, and the air velocity will increase, the air pressure will become smaller, and the pressure difference between the upper and lower parts of the body will be formed, and the pressure on the upper part of the body will be greater than the lower surface.

As a result, the air pushes the body downwards, causing the tires to increase the pressure on the ground, which increases the friction of the tires and thus the grip of the sports car. In this way, the handling of the sports car can be improved at high speeds.

2. If from the aerodynamic point of view, the low chassis is to increase the grip performance, then from the kinetic point of view, the low chassis also reduces the impact on the grip performance when the speed changes. The center of gravity is low, the body stability is good, and it is not easy to roll over when cornering at high speeds. The function of lowering the center of gravity during cornering, acceleration and deceleration is to minimize the effect of weight transfer, so that the impact of inertia on the grip of the tire can be minimized.

The disadvantages of a low chassis of a car.

1. When driving in a place with a large difference in the uphill and downhill gradients, there will be a situation of scraping the bottom when going straight, it is necessary to pay attention to: first try to let the people in the same car get off the car, reduce the load of the car, and increase the high ground clearance to a certain extent.

2. When the water is deep, the exhaust pipe is easy to enter the water, resulting in serious consequences of water ingress into the engine. It is necessary to first estimate the water depth and grasp the actual depth of the water before it can be considered. Otherwise, don't trespass.

Automobile chassis, drive system, driving system, steering system.

The chassis of a car is another important component after the engine. In the chassis there is a drivetrain, a driving system, a steering system, and a brake system.

Chassis: The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. The chassis is composed of four parts: the drive train, the driving system, the steering system and the brake system.

The chassis of a car consists of four parts: the transmission system, the drive system, the steering system, and the braking system. The role of the chassis is to support and install the automobile engine and its parts and assemblies, shape the overall shape of the car, accept the power of the engine to make the car move, and ensure normal driving.

The chassis of an automobile includes a transmission system, a driving system, a steering system, and a braking system. There are four main drivetrains: the power is transmitted from the engine to the drive wheels.

It consists of a clutch, a transmission, a universal transmission and a drive axle, among others. The drive system connects all car assemblies and components into a single unit, supports the quality of the whole vehicle, and ensures the driving of the car. It is a steering system consisting of frames, axles, wheels, suspension, etc.

Make sure the car is driving according to the driver's intentions. It is a braking system consisting of a steering gear and a steering transmission mechanism: according to the driving needs of the car, the car is forced to slow down, stop and stop safely and reliably in various places.

It consists of several relatively independent systems, each consisting of an energy supply, a control, a transmission, and a brake. The car mainly consists of a body system, interior, electrical system, and chassis system. Broadly speaking, chassis refers to the electrical system that takes away the rest of the body, except for the interior and exterior.

Chassis is a general term, not specific to a certain part of the car or a certain part of the structure; It is composed of four major systems, which are the drive train, steering system, driving system and brake system. So what exactly does the chassis do? First of all, it can play a supporting role, install the assembly of the engine and other components, and at the same time accept the power output of the engine, so that the car can produce motion, so that it can drive normally; Let's take a closer look at the functions of each of the four major systems of the chassis!

Transmission system. The transmission system, in layman's terms, is to transfer the power of the engine through various structural components and transmit the driving force of the engine to the driving wheels, so that the car can drive. What is the sequential process of automobile power transmission?

First of all, after the engine power output, it passes through the clutch, transmission, universal joint, transmission shaft, drive axle, final reducer, differential, half shaft, and finally transmits to the drive wheel to complete the transmission of engine power. The structural components mentioned above constitute the transmission system. It can be seen that the transmission system has the functions of deceleration and torque, acceleration and deceleration, and reverse gear; At the same time, there is also the effect of interrupting the power transmission and making the left and right wheels have different speeds, that is, differential speeds.

Steering system. The steering system is easy to understand, and the steering of the car is completed by the steering system. The function is to ensure that the driver can steer forward, left or right according to the driver's driving intention.

It is generally divided into mechanical steering and power power steering, and the current use is more power power steering, which is what we usually call hydraulic power steering or electronic power steering system. The effect is to make the steering do not need too much force, and the car does not need to turn the steering wheel many times when turning; There will be no serpentine when going straight; The vibration, swing of the wheels does not turn the steering wheel.

Travel system. The travel system consists of a frame, axles, tires, and suspension, among others. It is an important condition to determine whether the car can run normally, it not only has to accept the power transmitted by the engine, but also generate the driving force on the driving wheels to ensure that the car can drive normally; At the same time, through the role of tires and suspension, the impact of the ground on the body is reduced and filtered, the vibration impact on the car is reduced, and the driving stability and handling stability of the car are guaranteed.

Braking system. To put it bluntly, it is the brake system of the car. It ensures that whether we are driving, decelerating and stopping, or braking in an emergency and dangerous situation, we can provide sufficient braking power, and can make the car stop within a controllable range according to the driver's intention to avoid the occurrence of dangerous situations.

In addition, the braking system is also related to electronic assistance systems such as ABS anti-lock braking system and ESP body stability system, and the quality of the braking system also determines the degree to which these electronic auxiliary devices play.

It is generally composed of four parts: transmission system, driving system, steering system and brake system. Pay attention to maintenance.

1. Clean and scrub the chassis of the car regularly.

The automobile chassis is the closest part of the automobile parts to the ground, and in the process of driving, it often falls into the mud and sand, causing the automobile chassis to be stained with mud, garbage and other attachments. These pollutants will enter the chassis of the car, causing the pollution of the transmission system and other components of the car chassis, causing the friction between the parts to increase, accelerating the loss of parts, greatly shortening the service life of the car, and in rainy and snowy weather, the components in the rain and snow may corrode the parts of the chassis to a certain extent.

Therefore, we need to wash the chassis of the car regularly, and thoroughly clean the chassis frame, steering arm, steering tie rod, rotating shaft, tire fender and other positions after rain and snow to prevent the above parts from rusting.

2. Check the operation of each part of the vehicle chassis.

In the normal daily driving process of the vehicle, there will be no abnormal noise, and when there is a problem with the automobile chassis, there will be a more abnormal and huge sound, and the operation and control of the automobile will also be inconvenient at this time, for this reason, the operation of the above-mentioned parts needs to be analyzed in the process of driving the car, and the problem is found to be repaired in time to the maintenance plant.

3. Inspection and maintenance of automobile shock absorbers.

The shock absorber of the car is also installed in the chassis of the car, the shock absorber of the car needs to be maintained daily, the working state of the shock absorber will affect the stability of the car during driving, if the shock absorber of the car is in good working condition, it can directly affect the service life of other parts of the car, thereby increasing the economy of the use of the car.

The chassis of the car is composed as follows:
