The scooters that Mengwa played, there are so many technologies!

  I believe that everyone has seen a lot of videos about kids racing on the Internet, and even the pictures of adults riding on the track on the track. This kind of race vehicles can be said to be quite popular in foreign countries. Currently in our country, Shenzhen already has This type of event. Everyone thinks that such a mini-type car is just a professional toy. As everyone knows, its design and manufacture are actually very mature and delicate. It is not as simple as a toy.

From the appearance, you can see the obvious embracing steel frame:

The engine is mainly two-stroke, with 40cc or 50cc engine matching according to the needs of the owner. Of course, there are also bigger ones. But 50cc can have 16.8 horsepower. If you have a large displacement, it may be difficult to control in this car! And generally the large output is usually an adult ride. No one wants to give a first-time four-year-old child a 16.8-horse locomotive.

There is no gearbox on the power transmission. It is a single-speed structure. After all, the speed range that this small car faces is still within the range of single gear ratio. In addition, the power loss caused by the increase of the gearbox may be larger than the imagination. After all, the peak torque of the high output version is also about 10Nm. It may be more difficult to ride after the attenuation.

Like all cars, the power is as precious as gold and can't be wasted, so you can also see a very efficient transmission clutch and a thin drive chain in the car.

The tire is of course also a hot-melt tire for the track, but the interesting thing is that it is only 6.5 inches, and the tire width is only about 110mm, but it is already very wide for this car.

In the car you can see the pedals moving backwards and the rocker position adjuster. Of course, the brakes are also indispensable!

This large water-cooled row is not a fan of the car at all. Think about 50cc and more than 16 horses. The conversion is about 320 horses. It seems that such a large water-cooled row is not too much.

The fuel tank and other body parts are made of fiberglass. What is more special is that there is no front and rear suspension for this car. The tires that bear the main shock absorber function are the tires, and the flexibility of the frame itself, so it takes a lot of pains to adjust.

Daily maintenance and upkeep can effectively solve the sealing problem of hydraulic cylinders, extend the service life of hydraulic cylinders, and improve the work efficiency of construction machinery.
1. Regularly check the wear of the hydraulic cylinder seals, and if severe wear is found, it should be replaced in a timely manner.
2. Clean the hydraulic cylinder seals to prevent impurities such as dust and sand from entering the interior of the seals.
3. Use appropriate hydraulic oil and avoid using expired or non compliant hydraulic oil to avoid damage to the hydraulic cylinder seals.
4. Avoid using hydraulic cylinders under excessive pressure or load to avoid damage to the seals.
5. Regularly check the liquid level and pressure of the hydraulic cylinder to ensure its normal operation and avoid damage to the sealing components due to hydraulic cylinder failures.
6. When the hydraulic cylinder is stopped for a long time, regular maintenance should be carried out, such as applying anti rust oil, to prevent aging or deformation of the sealing components.
