The walking system is responsible for bearing the weight of the vehicle and its cargo, as well as ensuring smooth and stable movement. It consists of several crucial components such as the frame, front fork, front and rear shock absorbers, and wheels. Each of these parts plays an essential role in maintaining the vehicle's stability and offering a comfortable riding experience.
The frame serves as the fundamental structure of the motorcycle, providing a sturdy foundation made up of steel pipes and plates. Its purpose is to connect various components such as the engine, gearbox, front fork, and rear suspension, ensuring optimal strength and rigidity. In the case of smaller motorcycles, a spine-shaped frame is commonly employed, which is created through the stamping and tailor-welding of steel plates. Alternatively, motorcycles typically utilize a welded steel pipe frame, cradle frame, or a combination of steel plates and pipes. In instances where higher power engines are involved, motorcycles may feature a double-cradle frame constructed through welded steel tubes.
The front fork serves as the crucial linkage between the motorcycle's frame and the front wheel, providing optimal guidance. It consists of essential components such as the upper and lower connecting plates, steering columns, and a front shock absorber. The steering column and lower connecting plate are securely welded together, with the steering column being inserted into the front sleeve of the frame to enable smooth movement. To ensure flexible motion, axial thrust ball bearings are installed at the upper and lower journal parts. Additionally, the front fork is equipped with a front shock absorber to enhance the motorcycle's overall suspension system.
Shock absorbers, both front and rear, play a crucial role in maintaining the smoothness of a motorcycle. Their primary function is to lessen the vibrations caused by the impact load imposed on the front wheel. By effectively absorbing these vibrations, the front shock absorbers ensure a comfortable and stable ride for the motorcycle.
The rear suspension system of a motorcycle consists of the rear shock absorber and the rear rocker arm of the frame. This system serves as a flexible link between the frame and the rear wheel, absorbing shocks and vibrations caused by uneven road surfaces and slowing down the motorcycle's movements. It is responsible for bearing the weight of the motorcycle and ensuring a smooth and comfortable ride for the rider. Without this essential component, the motorcycle would be unable to navigate rough terrain and would be uncomfortable to ride. Therefore, it is critical to maintain and repair the rear suspension device of your motorcycle to ensure its long-term performance and safety.
The two wheels on a motorcycle serve different functions, with the front wheel acting as a guide wheel and the rear wheel serving as the driving wheel. These spoked wheels are made up of many components, including the outer and inner tires, rims, spokes, hubs, brake steel rings, bearings, and front and rear axles.
The rim or steel ring of the wheel is created by rolling and welding steel plates. The hub, on the other hand, is made of an aluminum alloy and is die-cast for precision. The brake steel rim is also die-cast and inlaid to form one single piece, complete with flanges to mount the spokes.
The spokes themselves are shaped similarly to bicycle bars and are the components that connect the rim to the hub. The wheel hub is equipped with a brake, while the front wheel has additional features such as a worm wheel and a worm for the speedometer. The rear wheel, meanwhile, is fitted with a drive mechanism for propulsion.
