The role of the geometric center plane of the car

The center surface: is a longitudinal center line of the car and the reference surface In the vertical plane, the car is divided into 2 parts with left and right dimensions symmetrical in the broadband direction, with marks on the roof and floor.Remember that the dimensions of all width directions of the car body are measured based on the central plane, and the broadband at the central plane is zero.

Some cars can see the center mark, and there are a series of mark points on the roof and bottom of the car body. These points are all on the central plane. With the center mark, you can measure the horizontal size conveniently and quickly. Throughout the maintenance process, all major processing control points on the damaged parts must be re-examined according to the vehicle data.

Geometric curves give people a sense of order. The appropriate use of these different lines can make the car look more beautiful. At the same time, when we roam the car kingdom, we should not ignore the beauty of the lines of various models or put forward our own useful insights on the use of their lines.

The car will be more stable in the process of driving, and the maximum speed will be higher when cornering, which is what we usually call not "floating".The same is true in collisions. Models with low center of gravity have a lower probability of turning over when they are hit by the side, which is more protective of the people in the car and safer to drive.

The main sale is tilted back. The back tilt of the main pin refers to the fact that the main pin is installed on the front axle, and its upper end is slightly tilted backwards, so that a sandwich angle is formed between the axis of the main pin and the ground perpendicular through the center line of the front wheel in the longitudinal plane of the car, which is called the back tilt angle of the main pin.

Car model classification The full name of SUV SUV is SportUtilityVehicle, which means sports multi-purpose car in Chinese. Nowadays, SUVs generally refer to those models based on the car platform, which have both the comfort of a sedan and a certain off-road ability to a certain extent.

What are the applications of flat four-pole mechanisms in automobiles?

1. It is mainly for the application of wipers in automobiles. The hinged four-bar mechanism of the two connecting rods, one is a crank and the other is a rocker, is called the crank rocker mechanism. The function of the crank rocker mechanism is to convert the rotational movement of the crank into the recicating swing of the rocker. Radar, automobile front window wipers and mixers are all applications of crank rocker mechanism.

2. Application examples: crank rocker mechanism, parallelogram mechanism, anti-parallel quadrilateral mechanism, double rocker mechanism, double crank mechanism, application example A B B D C 1 2 4 3 crank shake, parallelogram mechanism, anti-parallel quadrilateral mechanism, double crank mechanism, also There is a four-bar mechanism with a mobile vice..., and there are various types.

3. The basic transmission mechanism belongs to the mechanical field. It can change the direction and size of the force, and has a lever function. Its extension can also be called a four-connection mechanism. Examples of uses: closing operation and splitting operation in high and low voltage switches.

Is there any impact if the flat bearing of the car is broken

1. The flat shaft of the carThe impact of the damage: if it is light, it will affect the comfort. If it is light, the tire noise will become loud and the vehicle will run sideways, while if it is heavy, it will cause suspension damage, causing the steering system to fail and causing traffic accidents. It is recommended to replace it in time. Planar bearings mainly bear axial loads in the assembly body, which is widely used.

2. If the plane bearing is damaged, there will be a strange sound when hitting in the direction. The steering wheel becomes heavy and inflexible. If it is serious, there will be a strange sound during driving, affecting the operation performance of the whole vehicle. First, there will be a slight squeaking sound when the car is cold.

3. If the plane bearing of the car is broken, there will be abnormal sound when the vehicle is in the direction, the vehicle will run in the direction, the tire noise will increase during driving, the steering wheel will become heavier, etc. If the above situations occur in the vehicle, you should go to the repair shop or 4s store to find a professional for a detailed inspection.

4. If the plane bearing is damaged, the vehicle's shock absorption system will produce abnormal banging noise due to friction, thus affecting the steering system of the vehicle. Therefore, when we use cars on a daily basis, we should try to avoid highways from passing through potholes to prevent flat bearings from being damaged by huge impacts.

5. Most of the damage to flat bearings is basically caused by poor lubrication or more dust. After opening the engine cover of the car, you can see the top of the tower. The function of the top of the tower is to fix the front shock absorber. There is a dust cover on the top of the tower, and the flat bearing can be seen after removing the dust cover.
