What are the chassis parts of a car?

Automobile chassis parts are divided into: transmission system: clutch, transmission, final reducer, half shaft, universal joint, transmission shaft; Travel system:

Frame, balance bar, axle, wheel, ingots beam, shock absorber, horn, arm, three-way catalysis; Steering system: steering axle, steering tie rod; Brake system: brake disc, brake cylinder, brake pad.

Automobile chassis construction and maintenance methods:

1. Transmission system:

1) Clutch: It is to ensure that the car starts smoothly, shifts smoothly, prevents overload during transmission, and prevents the impact of torsional vibration.

2) Transmission: It is used to coordinate the speed of the engine and the speed of the wheels, so that the engine performance can be released to the best.

3) Final reducer: It is a component that reduces the speed and increases the torque during the transmission process. The speed of the transmission can be reduced in order to obtain a relatively high output torque, so as to obtain a greater driving force.

4) Half shaft: It is also the driving shaft, the shaft that transmits power.

5) Universal joint: It is a device that regulates the steering of the car and belongs to the vector transmission of power.

6) Transmission shaft: It is installed between the transmission and the rear axle, and the torque and rotational power brought by the transmission are transmitted to the rear axle.

2. Driving system: (1) Frame: It is a frame used to carry various parts of the chassis, and it is also a protective frame to withstand external pressure.

2) Equalizer bar: It is used to improve the handling performance of the car, especially in the process of cornering. (3) Axle:

It is used to transmit the forces brought by the frame and wheels in all directions. (4) Wheels: Carrying and rolling is his final choice.

5) Yuanbao beam: used to carry the engine and gearbox, but also to strengthen the strength of the body. (6) Shock absorber:

It is a passage for exhaust gases. Make it into a harmless carbon dioxide, water, nitrogen catalytic converter.

3. Steering system: (1) Steering shaft: increase the rotational force given by the steering wheel, so as to smoothly change the direction of force transmission. (2) Steering tie rod: coordinate with the steering shaft to complete the corresponding steering work.

4. Braking system: (1) Brake disc: At the same time, it acts on the brake pad to brake the vehicle, providing a friction surface.

2) Brake cylinder: provide power to push the brake pads to make them rub against the brake disc to play a braking role, which is the function of giving braking courage. (3) Brake pads:

Friction with the brake disc to achieve the braking effect.

The vehicle is composed of four parts: powertrain, chassis, body, electronic and electrical, the powertrain provides power for the vehicle, the body provides space for people or objects, the chassis meets the requirements for vehicle movement, electronic and electrical appliances on the car, and the control system. In addition to the drive part and the body, the chassis is also the main component of the car, which is composed of wheels, wheel hubs, wheel bearings, braking system, suspension system, axle support springs, lateral stabilizers, transverse stabilizers, shock absorbers, steering supports, half shafts, final repellents and chassis adjustment systems.

For a mid-range car, these components account for 20% of the total weight and 15% of the production cost. The chassis is the connecting part of the vehicle and the road surface, through which the functions of the vehicle are realized, mainly including: the transmission of driving torque (overcoming driving resistance and acceleration), the control steering and vibration damping of brakes, clutches and accelerator pedals.

The role of the chassis is to support and install the assembly of the automobile engine and its various parts, 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.

1. Drive train: The power emitted by the automobile engine is transmitted to the driving wheels by the drive train. The drive train has the functions of deceleration, speed change, reversing, interrupting power, inter-wheel differential and inter-axle differential, etc., and works with the engine to ensure the normal driving of the car under various working conditions, and has good power and economy.

It is mainly composed of clutch, transmission, universal joint, transmission shaft and drive axle.

Clutch: Its function is to make the power of the engine and the transmission smoothly engaged or temporarily separated, so that the driver can start, stop and shift the car.

Transmission: It is composed of transmission housing, transmission cover shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing and control mechanism and other parts, which are used for automobile speed transmission and variable output torque.

2. Driving system: It is composed of frame, axle, suspension and wheels. The function of the driving system is:

a.Receiving the power of the drive train, the traction force is generated through the action between the drive wheel and the road surface, so that the car can run normally.

b.Bears the total weight of the car and the reaction force of the ground.

c.Alleviate the impact of uneven road surfaces on the body, attenuate the vibration of the car while driving, and maintain the smoothness of driving.

d.Cooperate with the steering system to ensure the stability of car handling.

3. Steering system: The special mechanism used to change or restore the direction of travel on the car is called the automobile steering system. The basic components of the steering system.

a.The steering control mechanism is mainly composed of a steering wheel, a steering shaft and a steering column.

b.Steering gear, a mechanism that transforms 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.

c.A steering transmission 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.

4. Brake system: A series of special devices used on the car to make the outside world (mainly the road surface) exert a certain force on some parts of the car (mainly the wheels), so as to force braking to a certain extent, collectively referred to as the braking system. Its role is:

Make the moving car force to slow down or even stop according to the driver's requirements; Stable parking of stopped cars in various road conditions, including on ramps; Keep the speed of the car going downhill steady.

The automobile chassis is generally composed of four major systems: transmission system, driving system, braking system and steering system. Its function is to support and install the automobile engine and its various parts, 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 automobile chassis is mainly composed of four parts: transmission system, driving system, steering system and braking system, and the main accessories of each part are as follows:

1. Transmission system:

The transmission system is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft.

2. Driving system:

The driving system consists of the frame, axles, wheels, and suspension of the car.

3. Steering system.

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.

4. Brake system.

The braking system is mainly composed of four parts: energy supply device, control device, transmission device and brake. The main function of the braking system is to slow down or even stop the moving car, stabilize the speed of the car driving downhill, and keep the stopped car still.

The automobile chassis is a system that consists of four parts: the drive train, the driving system, the steering system and the brake system.

1. The transmission system structure of the automobile mainly refers to the power transmission device between the engine and the driving wheel, which is composed of clutch, universal rotation device, and drive axle and other parts. 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.

2. The driving system of the car 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. The steering system of the car mainly refers to a series of devices used to change or protect the direction of the car or reverse. For example, the steering control mechanism, steering gear, steering Edaga 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.

4. The braking system refers to a series of special devices that can generate braking force on the car. 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 wearing parts include gearbox, front axle, rear axle accessories, wheels, etc. After a certain number of kilometers of driving, to judge the condition of the car, in fact, is to check the degree of damage to its wearing parts. Any part has a service life, it's just a matter of comparing the length of time or the shortness.

Our definition of a consumable part is a part of a car that is normally consumed during the life cycle of a car and is not damaged by an accident, which is called a consumable part.

Specific introduction of chassis wearing parts:

The chassis is the main component of the automobile, which is composed of wheels, wheel hubs, wheel bearings, braking systems, suspension systems, axle support springs, transverse stabilizers, transverse steady and prudent rods, shock absorbers, steering support devices, half shafts, final reducers and chassis adjustment systems; 2. For an intermediate car, these parts account for 20% of the total weight and 15% of the production cost; 3. The chassis is the connecting part of the vehicle and the road surface, through which the functions of the vehicle are realized, mainly including: the transmission of driving torque (overcoming driving resistance and acceleration), the control steering of the brake, clutch and accelerator pedal and the damping cavity.

There are drivetrains, driving systems, steering systems, and brake systems in the chassis of automobiles.

The drive train is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft. The function of the drive train is that the power emitted by the automobile engine is transmitted to the driving wheels by the drive train, and the drive train has the functions of deceleration, speed change, interrupt power, inter-wheel differential and inter-axle differential, and work with the engine. It can ensure the normal driving of the car under various conditions.

And it has good power and economy. The driving system consists of the frame, axles, wheels, and suspension of the car. The function of the driving system is to accept the power of the drive train and generate traction through the action of the driving wheel and the road surface, so that the car can drive normally.

Bears the total weight of the car and the reaction force of the ground. It alleviates the impact of uneven roads on the car body and attenuates the vibration of the car while driving.
