  • What is the difference between a motorcycle and a car when it is turning

    Under normal circumstances, motorcycles are crashed in the corners, and cars are turned outwards if they turn from corners. Why is this?

    To understand this problem, we first need to know what is circular motion. The particle moves on a circle with a radius of the center r at a certain point, that is, the motion whose trajectory is a circle when the particle moves is called "circular motion". It is one of the most common curve movements. For example, the rotor of the motor, the wheel, the pulley, and the like are all in a circular motion. In circular motion, the most common and simplest is a uniform circular motion. The circular motion provides the acceleration required for the moving object with centripetal force. This centripetal force pulls the moving object toward the center point of the circular trajectory. If there is no centripetal force, the object will move linearly following Newton's first law. Even if the object rate is constant, the speed direction of the object is constantly changing. That is, in a uniform circular motion, the linear velocity changes (direction), and the angular velocity does not change.

    With this in mind, let's look at the force analysis of a car at a constant corner. When turning a car, the car uses the "sliding angle of the tire to generate steering force" to drive the car to turn, so when the steering wheel turns to the direction of turning, the car body will start to turn in the direction of turning, but because of the centrifugal force on the body There will be an impact, so the body will tilt towards the outside of the steering.

    In contrast, motorcycle tires are "using the camber's camber angle to produce lateral force", which is called the "extroverted thrust" force to drive the car to turn, then the motorcycle body will turn to want to turn The direction is tilted and then turned. Therefore, compared with the tire for automobiles, the tire shape of the motorcycle is circular in order to obtain a large angle of camber angle and a small radius of the tire cross section.

  • Why is the motorcycle's oil meter inaccurate

    Everyone has the same experience more or less, that is, no matter which motorcycle you are riding, you will always feel that the oil meter on the motorcycle's meter is not very accurate. After filling up the oil, although the oil meter will naturally indicate the position to the full grid, but it will not slowly decline with the consumption of oil, reflecting the real oil quantity, but the indicator of the oil meter will drop as soon as it indicates a drop. One or two grids, some motorcycles even drop to half of the readings.

    Some motorcycle fuel gauges are in a very long state, but after they have dropped a grid, they will soon be finished. I have heard that this is a simple theory that the motorcycle manufacturer wants to give users a good fuel consumption, or some people say that this is a normal phenomenon. Its practical scientific explanation is a simple theory. Calculating the corresponding amount of oil by generating different resistances from the height of the pontoon is the way most models are used. But why do some motorcycles have some motorcycles that are not allowed? The first question is related to the shape of the barrel.

    Motorcycle oil drums are not as square as motorcycles. Usually, for the shape and space of the motorcycle, the fuel tanks of motorcycles have many different angles, so the oil gauges corresponding to more than half of the oil will be indicated. It is not enough, even if it is accurate, because of this, so often the oil gauge pointer on the motorcycle is already in the end, in fact, there is at least 1/4 liter capacity in the oil drum, and some motorcycles even have 1/2 liters of oil. In addition to the need to supply emergency backup oil, it is basically the result of the shape of the barrel. This question is actually nothing to say, there is nothing too much mysterious.

    We believe that the purpose of the oil meter is not to let the owner of the motorcycle ride the oil without knowing it, so the oil meter runs slower when the oil is more, as long as it consumes half of the gasoline, it can be truly from the instrument. In response to the oil storage information, it is already a competent fuel quantity indicator. In fact, you can also know the cruising range by recording the mileage.

  • The benchmark for motorcycle brake technology

    Compared with the traditional brake, the CBS brake is equipped with a small displacement motorcycle of the CBS brake system. Even a novice can complete a smooth stop by a single operation. As shown in the figure below, when the driver holds the brake handle, the braking force It can be properly distributed to the front and rear wheel brakes to complete the brake and complete the stop. Through the CBS system, the braking force is reasonably distributed to the front and rear wheel brakes to effectively control the braking distance, and the braking efficiency is much better than the traditional front and rear independent braking systems.

    Compared with the brake effect of the traditional brake and the structural difference of the brake, the structure of the CBS system is not complicated, and can be changed to the CBS brake system based on the traditional brake system; compared with the ABS brake system, CBS system The dynamic system has obvious cost advantages. At the same time, the structure of the CBS brake system and the later maintenance are simpler. However, CBS only reduces the probability of the rear wheel lock caused by excessive braking force, and there is still the possibility of locking in the front wheel.

    According to the analysis, the CBS brake system is more suitable for small displacement models, and the novices are not skilled enough to use the front brakes (here, the novices give up using the front brakes or tap the front brakes), the blind hand alone can use the front brakes to cause accidents. occur. Due to the higher cost of ABS and the complexity of structure and maintenance, it is more suitable for large and medium-sized displacement models.

    Is there any CBS and ABS concentrated in one motorcycle? Yes, that is the C-ABS linkage anti-lock system. Honda applied the Combined ABS system on the new generation flagship wagon ST1300 released in 2002, namely the linkage ABS brake system. The interlocking ABS brake system can redistribute the braking force and has anti-lock function, which becomes the benchmark for motorcycle brake technology. Since then, the linkage ABS brake system has been widely used in Honda's new models. The Honda's ST1300ABS, VFR1200F DCT, CTX1300 ABS and NC750 ABS are all equipped with a linkage ABS brake system.


  • Combination Braking System helps to improve the safety of the motorcycle

    The combination Braking System is called CBS. It is completely different from ABS. The core function of CBS brake is that the Cavaliers can obtain proper and effective braking force on both wheels when they operate the front brake separately or separately. . In other words, regardless of whether the Cavaliers operate front or rear brakes, the CBS system can reassign the Cavaliers' wishes to the front and rear wheels, allowing the motorcycle to slow down in the shortest distance. The principle of front and rear linkage braking is actually very simple, that is, the point components are added according to the mechanical principle, so that the single brake rear brake or the single brake front brake can be braked together before and after.

    Compared with the ABS brake system, the CBS brake system has a simple structure, and the CBS brake system has a significant price advantage. There are many types of CBS. The common ones are usually in the form of “front brake independent, rear brake linkage front brake”. CBS has many different classifications and structures. In the final analysis, the design theory and principle of CBS are the same. This time we measured the DR160 with the form of front brake independent, rear brake linkage front brake

    When the motorcycle uses the CBS system, the phenomenon of “braking after individual operation and locking of the rear brake” can be reduced. By the distribution of the CBS distributor, the braking force can be reasonably distributed to the front and rear wheel brakes, reducing the occurrence. The brake force generated by the excessive braking force of a single brake is increased, and the deceleration during braking of the motorcycle is improved under the premise that the brake is effective, and the probability of locking the rear brake is greatly reduced, thereby improving the safety of the motorcycle.
