Every part of the body has its function. The rear arm, an important role that connects the rear wheel and the frame, is often neglected when the user chooses the car. At the beginning of the design, the manufacturer needs to spend a lot of time designing the rear rocker. From the length, width and angle to the material selection, each part affects the dynamic performance of the vehicle. The swing arm needs to bear the forward driving force brought by the rear wheel when accelerating, and the force brought by the braking, which can guarantee the stability of the rear wheel.
The type of swing arm of different shapes and materials also affects the stability of the body in driving.
The representative model of this kind of arm is the Café, which is mainly used to provide a strong connection between the frame and the rear wheel.
Due to the insufficient density of the raw materials for manufacturing, the bearing capacity cannot be achieved. The rear absorption needs to be installed close to the axle of the wheel, and the force of the rocker arm after the distribution of the round pipe will result in uneven force of the vehicle body.
Compared with the cylindrical arm, the arm of square tube changes the position of shock absorption. We should avoid the tilting of the body to any side, and there are more ways to install the absorber. However, there are still some defects. After using the ideal materials, in the face of heavy-duty vehicles, it still can not guarantee sufficient support and stability.
This is an upgraded version based on the first generation of square arm. The square tube is superimposed on the original tube to make the rocker arm form a triangular structure.
From a mechanical point of view, it is possible to distribute the pressure more evenly to ensure the stability of the body.
As the displacement and horsepower of the vehicle increased, the triangular arm came into existence during this time period. Its density is stronger, but in order to leave working space for the chain, the upper beam has to be cut thinner.
At the same time, although the metal material can withstand the tensile force, in the face of intense driving, its ability of anti-stress is still slightly insufficient.
In order to avoid the impact on the chain and resistance to stress, the designers have inverted the upper triangle to improve to create this kind of arms.
This design is also the mainstream in recent years, and the overall strength exceeds other types.
It is undoubtedly the most suitable for comprehensive conditions in terms of comprehensive performance, and the manufacturing cost is relatively low.
As the name implies, it means that the arm which is installed unilaterally and it can be more expensive, but in terms of practical effect, it does improve the handling and flexibility.
If you are also a motorcycle enthusiast, then you can not miss our motorcycle tool. The first reason is for the usual small maintenance of motorcycles. The maintenance of motorcycles is relatively simple, such as changing the oil, cleaning the chains, tightening the screws, etc. It can save money and also a lot of fun. The second is when running for a long distance, you can carry them as an emergency.
