■ Handling and maintenance of 4WD

First, four-wheel drive operation 1. The correct way to put the car: the right hand palm up the four fingers and the mother finger respectively pinch the bottom of the car and the car shell, so as not to affect the rotation of the four wheels, open the switch with the left hand, will The car is placed smoothly in the track, the car will fly along the runway, the fish will get water, and the laps will be circling... 2. The correct way to pick up the car: the right hand palm is facing up, the middle finger is sticking to the runway center When the thumb waits for the car to touch the middle finger, the two fingers press the bottom of the car and the car, respectively, and quickly push the car to the left hand switch of the runway. Note: (1) Do not hinder the rotation of the wheel, otherwise the gear may be hit. [2] When picking up the car, you can't hold the car on the runway by hand.

Second, the maintenance of the four-wheel drive To maintain the high performance, high speed, long life of the four-wheel drive, it must be necessary maintenance.

1. Pre-use maintenance (1) Lubrication: Any two objects in contact with each other will inevitably generate friction when moving relative to each other. Friction will waste power and wear the surface of the parts. Lubricating oil can reduce frictional resistance, reduce power loss and reduce wear and tear on the parts. ,Extended service life. Therefore, in the four-wheel drive, the lubricant should be evenly applied on any part with relative motion. The function of the lubricating oil: lubrication, cooling, cleaning, sealing, anti-corrosion, etc. (2) No-load running-in: Put the assembled four-wheel drive on a small wooden block, and open the switch in four-wheel suspension (best battery is not very good). The idle running-in time is about five minutes. The effect of no-load running-in: After the airborne running-in, the surface of the tooth becomes smooth, the burr is reduced, the new motor rotates smoothly, and the gears are also very consistent, so that the high-speed driving effect can be achieved; otherwise, if the gear teeth If the combination is not good and the lubricant is insufficient, it will send out strange noises. The motor is burdened, and the scorching smell appears. The prerequisite for running-in is to get good lubricant.

2. Maintenance after use To ensure the high speed, long life and maintenance of the car, it is very important. (1) Check the situation and conduct a comprehensive inspection of the vehicle components and performance. (2) In time for dust removal, use cloth or paper to remove dirt and dust from all parts of the body. (3) Replace the parts, the car should be carefully inspected, and the curved front and rear axles should be found. The heavily worn gears and bad parts should be replaced in time. (4) Lubrication, re-apply the lubricant in time, otherwise it will reduce the speed and shorten the life. (5) Fasten and loose screws should be tightened. Especially for parts such as guide wheels, if they are loose, they will fly out of the runway while driving. In addition, the parts will be shown as zero points during the game. 3. The beauty of the vehicle (beautification) A perfect car should also have a beautiful and beautiful appearance, so that the vehicle looks like a one, constitutes a real mini-car. This is a test of the comprehensive ability of the players, not only electrical, electromagnetic, mechanics , mechanical mechanics, air science, dynamics knowledge, etc., but also to master some aesthetics, work on decoration and painting. From this you can get great fun. Beautiful car body, clear and arguable when driving, radiant. In the game field, people will also pay attention and praise, which best reflects the skills and aesthetics of the players. Beautifying four-wheel drive is generally divided into two parts: changing shape and coloring. This is all about the classmates themselves, there is no uniform standard.
