What is a car chassis and what is a chassis car?

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.

The automobile chassis is composed of four parts: the transmission system, the driving system, the steering system and the brake system. 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 of the car is the bracket of the whole vehicle, with the engine added on top and the transmission and tires installed below, and the car is completed.

Hello, the chassis is composed of four parts: driving system, braking system, transmission system, steering system; Driving is by four tire assembly, braking is the brake assembly, transmission is half shaft, transmission shaft, steering is the need for electronic power or mechanical power assist this set of assembly.

The lowest structure of the car,

I don't understand this, isn't it just a new head without a body!

The chassis refers to the combination of four parts of the transmission system, the driving system, the steering system and the brake system on the car, which supports and installs the automobile engine and its various components and assemblies to form the overall shape of the car, bear the engine power, and ensure normal driving.

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.

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.

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 automobile chassis can be divided into two types according to the structure, namely the load-bearing body and the non-load-bearing body.

The non-load-bearing body chassis is characterized by longitudinal beams connected to the front and rear, and the whole chassis has high strength and large load-bearing, but the comfort is poor. It is generally used for large vehicles with high requirements for carrying capacity, such as buses, large buses, trucks, etc. There are also a small number of hardcore off-road that emphasize off-road performance will also use non-load-bearing bodies to strengthen chassis rigidity, such as the Jeep Wrangler.

The load-bearing body is mostly a cage body, and the design has been strengthened in key parts, such as the front of the car, parking spaces, and the side of the car. It is easy to assemble, safe and stable. However, the manufacturing process is complex and costly. At present, the vast majority of cars use load-bearing bodies.

Suspension system. Intake and exhaust systems.

Transmission system. Fuel system.

Gear shift pedal system.

Suspension system. Steering system.

Wheel tire system.

Braking system. These are the chassis parts.

There is a drivetrain under the chassis of the car, and the engine front-running system includes many parts.

It is composed of four parts: the drive train, the driving system, the steering system and the brake system.

<> "The function of the automobile chassis is to support and install the automobile engine and its parts and assemblies, form the overall shape of the car, and receive the power of the engine, so that the car can move and ensure normal driving. The chassis of an automobile consists of four parts: the transmission system, the driving system, the steering system, and the braking system.

Transmission system: It consists of a clutch, a transmission, a universal transmission and a drive axle.

Driving system: It consists of a frame, axles, wheels, and suspension.

Steering system: It consists of a steering wheel, a steering shaft, a steering column, etc.

Braking system: It is composed of service brake system, parking system, emergency braking system and auxiliary braking system.

Two chassis configurations – load-bearing and non-load-bearing.

The load-bearing body is characterized by the absence of a frame, the body is the mounting base of the engine and suspension assembly, the body has a frame function and bears all loads. As a result, the whole body is more complete. The engine, drivetrain and suspension system are all installed in designated positions on the body.

The most important feature of the non-load-bearing body is that it has a rigid frame, which usually consists of longitudinal members and crossbeams passing through the main body, which has high strength and good torsional resistance. The car's powertrain, suspension system, and body are flexibly connected to the frame by rubber pads or springs. The frame is the foundation that supports the entire vehicle, while the body only bears the gravitational force of the loaded people and cargo.

At present, the use of load-bearing bodies in automobiles is more extensive than that of non-load-bearing bodies. Since the load-bearing body does not have a bulky steel beam chassis, it can have better interior space and reduce the weight and volume of the vehicle accordingly. However, the non-load-bearing body has not been eliminated because of the emergence of the load-bearing body, because the non-load-bearing body also has the advantages that the load-bearing body cannot achieve.

As mentioned above, the non-smug body has very high strength and will therefore still be used in professional off-road vehicles and trucks. The I-beam chassis can greatly reduce the deformation of the body due to uneven roads and heavy loads, and when traffic accidents occur, it can be more resistant to collisions, thus protecting the passengers in the vehicle. However, the weight and fuel consumption of the respective vehicle also increases.

If the large cabin is not used, the interior space of the vehicle will be very small, so the non-load-bearing body will not be used in the average family vehicle.
