"Okay, okay, Mr. Thomas, let's go to the next area and have a look!"
Dong Mingwu said continuously.
Thomas has discovered that this child is a little "abnormal" and his behavior is "weird". He just asked him about the identity of the child. Dong Mingwu hesitated and only said that he was a student of Professor Xiong Huaizhi. How could a student be so "unscrupulous"? Even the machinery in Shanghai
Bureau Chief Dong Mingwu was also respectful in front of him.
But Thomas didn't say anything and led everyone into the next area.
The car that comes out of the assembly workshop is ready to start, but it still needs to go through the last procedure, which is inspection, so the last area is the inspection area.
There is a small screen placed on each operating table. The screen is connected to a device similar to a computer case. The other end of this device seems to be a scanner. The worker holds it in his hand and scans the gaps in the mechanical parts.
Scan back and forth, and then various data will be displayed on the screen. Workers will then analyze the various data to determine whether there are problems. This is a German digital imaging control system, which already has the shadow of some CNC machine tools.
"This is the inspection area. We at Volkswagen attach great importance to the quality of cars. Although we believe that there are no problems with the assembled cars, we still need to conduct strict inspections to discover potential quality problems during the production and assembly process. We will try our best to
Unqualified products may be refused to leave the factory.
In this area, the master workers have to open the engine compartment, check the components inside, and then add necessary liquids such as antifreeze, booster oil, glass water and lubricating oil to preheat the sides of the car body.
They did this to install side anti-scratch strips in the preheating area. Although the quality of the paint surface has been checked during the previous spraying process, it still needs to be inspected before leaving the factory to see if the paint surface was damaged during the final assembly process.
Next, in order to check that there are no problems during the assembly process, tire alignment testing must be performed. Vehicles that pass the testing must be driven to the shower room for sealing performance testing.
In the sealing test, the amount of water sprayed out by the nozzle is several times greater than the amount of rain in normal heavy rains. Only in this way can the sealing performance of the vehicle be tested. Only vehicles that pass the test can proceed to the next process, and vehicles that fail the test can proceed to the next process.
Then it will be directly returned to the production line for reassembly. Vehicles that pass the test will be tested on various test tracks in the factory simulating various road conditions to ensure the quality of the vehicle before leaving the factory. After the test is completed, it will be driven into the ditch for final inspection.
Thomas introduced everyone in detail. Even though he had said these words countless times, he still spoke meticulously to the visiting guests, which shows the serious work attitude of the Germans.
Xiong Huaizhi, Liu Lang and others listened to the introduction while watching the work of the workers, especially Liu Lang. Every process was remembered in his mind.
More than ten minutes later, they finally arrived at the end. At this time, a brand-new Santner car had been inspected and was about to proceed to the next stage of road testing.
"1.6L in-line 4-cylinder 8-valve carburetor gasoline engine, maximum power of 87 horsepower at 5200 rpm, 4-speed manual transmission, no leather seats inside, no anti-lock brake system, no airbags and remote key, low
There is no place to match it!”
Liu Lang looked at the car and thought to himself, in his eyes, the appearance of this Santner was extremely "rough". It was all white and square in shape, just like an iron box. If it were placed thirty years later,
, I’m afraid those young people would rather ride bicycles than ride in such a car, it’s too embarrassing.
Liu Lang gently patted the front of the car. It had a metallic feel. Now the car body is completely made of metal plates, even the bumpers are the same. It is not like the high-strength engineering plastics that will gradually evolve in the future. If this kind of car
If you hit someone, unless you are the Hulk, all ten lives will be lost.
"Okay, we've finished looking at the assembly workshop. Follow me to the office. I'll tell you about the parts!"
Thomas led everyone out of the workshop and walked towards the office building not far away.
"Hello everyone, my name is Osman and I am an engineer. Now, let me introduce to you the structure of various parts of Volkswagen!"
In the conference room, a middle-aged engineer in his forties stood in front of a projector. This projector was similar to the laser printer thirty years later. It consisted of a box-like chassis and an imaging lens.
After putting it in the case, turn on the switch, adjust the imaging lens, and a clear image will appear on the white curtain in front.
This kind of projector is the oldest engineering imaging machine, but it is not available in China yet.
At this time, an image has appeared on the white curtain, which is a drawing of five parts. After magnification, every detail and indicator can be seen clearly.
There are many parts in a car. The most important parts are engine parts and transmission parts. For example, the engine has engine assembly, oil pump, oil nozzle, tensioner, cylinder block and other parts.
Transmission accessories include transmissions, transmission shift lever assemblies, reducers, clutches, universal joints, universal balls, universal balls, etc.
Of course, these parts are not within the goal of localization. In fact, the country has previously made requests to the Germans to localize engines and transmissions, but the Germans politely refused, saying that the requirements for these two parts were too high.
, even if the technology is handed over to China, localization will not be possible within 20 years. After on-site investigation, the relevant national departments also found that the other party was right. Let alone 20 years, even 30 years may not be possible.
Unable to localize it, we agreed to the other party’s proposal.
Therefore, the main parts of Volkswagen’s localization are other parts.
Mainly include steering system accessories: mainly steering gear, steering knuckle ball joint, steering knuckle steering wheel, steering gear, assembly booster, steering tie rod, power pump, etc.
Travel accessories: electrical instrument accessories, rear axle, air suspension system, balance weights, steel plates, tires, leaf springs, half shafts, shock absorbers, steel ring assemblies, half shaft bolts, axle housings, frames, and assemblies
Car interior: car carpets (foot mats), steering wheel covers, steering wheel power balls, curtains, sun gear, etc.
Car exterior decoration: wheel covers, body color strip stickers, license plate holders, weather shields, etc.
Body and accessories: wipers, automotive glass, seat belts, airbags, instrument panels, static elimination antennas, static belts, etc.
In addition, there are some brake system accessories, such as brake pads, brake drums, brake pedal assemblies, brake master cylinders, brake cylinders, electric hydraulic pumps, brake camshafts, brake rollers, brake pins,
Brake adjustment arm, brake chamber, hand brake assembly, parking brake assembly, parking brake operating lever assembly and other parts.
Taken together, these various parts can account for almost 80% of a car. However, in terms of technical content, these 80% of the parts are equivalent to 20% of the entire car.
But even this measly 20% will take the country six to seven years to study.
