Most of the crashes caused by low-speed non-impact in motorcycles are caused by the instability of the center of gravity and the sudden drop of adhesion between the wheels and the ground. In addition to the driver's skills and experience, the right model can greatly reduce the chance of crash. The models sold in China are: street running, Prince, pedal, curved beam, off-road and so on. In dealing with anti-straight road crashes, the best performance is the pedal, the other difference is not big, because the pedal wheel diameter is small, the same speed pedal wheel speed is faster than other cars, according to the centrifugal force F = (mass * speed squared) / rotation The radius and the same speed pedal wheel have the highest centrifugal force, which is beneficial to obtain the best stability. In dealing with corner crashes, there are many factors to consider. First, the tires with high adhesion and rounded corners have good cornering performance. The front* and the ground angle are closer to the vertical, the better, the front of the prince* is smaller than the ground angle. When bending, the tire is easy to skid. For an experiment, when the kitchen knife is perpendicular to the cutting board, it is difficult to move the kitchen knife parallel to the left and right. The angle of the kitchen knife is small and the angle of the cutting board is small. It is easier to move the kitchen knife parallel to the left and right. The smaller the ground angle, the greater the risk of a corner crash due to the front wheel slipping. When the front-to-earth wheel-to-ground gravity ratio of the motorcycle is 1:1, the center has the best cornering performance at the midpoint of the wheelbase, and the slight braking does not cause the tail-side sliding to the front of the vehicle. The gravity ratio is generally 1:3. After the center of gravity*, the tail of the turning brake will slide sideways to the front of the car. Therefore, players who like to bend down and do not choose the Prince car. The advantage of the Prince car lies in the stability of the straight cruise (front* and The ground angle is small, and the front axle has the feeling of dragging the wheel, just like the kite tail stabilizer. The best stability of cornering is the street running. Although the cross-country pineapple tire has a strong adhesion, the runners are driving on the fuel tank, the center of gravity is low, and the stability is better than the off-road. A helmet with a mask allows you to look at the road surface when you are blowing in the wind, raining and flying sand. As for the bumper and knee pads, it only works after the crash, and is not in the scope of discussion.
Second, anti-straight road crash
The road conditions in China are complicated. Even if you are driving at a straight road, you should be vigilant. Regardless of the car you drive, you must maintain a high sense of driving. For example, at the fork in the road, observe the cars, people and animals on both sides, which may have the possibility of running out of the driveway, and if so, slow down slowly. Keep a safe distance from the vehicles in front and rear, especially the passengers, taxis, and CMBs of the passengers. Do not stick behind them. If the front car stops slowly, keep a distance of two meters when passing it to prevent the other party from suddenly opening the door and getting out of the car to prevent the door opened by the other party. Also pay attention to the road conditions, big pits, LaJi, sewer cover, sand or watermelon rind, which may have sharp objects, should be decelerated. The ground is slippery at a low speed, and the brakes must be artificially ABS, that is, do not brake, leaving some room for wheel rotation. Always pay attention to the rearview mirror and turn the turn signal to avoid rear-end collision. In the evening, you must turn on the headlights. Some people don’t turn on the headlights at night to save money. Don't drive at night. There are often construction pits, no lights scrapped cars, cars parked on the side of the road due to malfunctions, etc. Low speed allows you to have enough warning to avoid danger. Do not drive or ride when you are drunk or blind, or have a sudden drop in vision.
Third, anti-bend road crash
If you want to slow down before turning, hit the direction light, if you suddenly brake suddenly, you will fall. After bending over and steady, I saw the preparation before the bend. Buying a car should pay attention to the local road conditions. There are more straight roads than curved roads. You can cruise for a long time. Choose a Prince. There are more detours than straight roads. If you want to press the bend, you can choose to run on the street. If there is sand on the road or there is a car in front, the slower the cornering speed, the better. Be sure to look around before turning at the * intersection to ensure safety.
Fourth, anti-parking crash / anti-external force impact crash
Sometimes you are very careful, you have not dropped the car on the road, but the parking is lax, forget to hit the foot and leave, or park in dangerous areas such as construction sites, cars / people, your car is too * near other people's car It is difficult for others to pick up cars, entrances and exits, etc. If you are careful, you can avoid them. Before you put your car, you should fully observe the surrounding conditions, including whether there are worn billboards on the top of the head, windows that may throw objects, etc., to ensure the safety of your car.
