What Causes Motorcycle Handlebar Wobble When Going Over Speed Bumps?

Motorcycle handlebar wobble when going over speed bumps is caused by insufficient front tire pressure and loose axle nuts. Introduction to Tire Pressure: Tire pressure refers to the air pressure inside a tire, which determines many vehicle performance aspects such as load capacity, power, and braking performance. Both excessively high and low tire pressure will shorten tire lifespan. Low tire pressure increases tire deformation, making sidewalls prone to cracking and accelerating wear. High tire pressure causes excessive stretching deformation, reducing tire elasticity and increasing the risk of blowouts upon impact. For daily vehicle use, appropriate tire pressure should be selected, and the good habit of regular tire pressure checks should be cultivated. Introduction to Axle: An axle, as the name suggests, is a system composed of a wheel and an axle. This system can rotate around a common axis, equivalent to a lever system with the axle center as the fulcrum and the radius as the lever. Therefore, an axle can change the torque moment, thereby altering the magnitude of torque.

What is the difference between a handbrake and a footbrake?

The difference between a handbrake and a footbrake is that the handbrake is an auxiliary brake, while the footbrake is the main brake of the vehicle. Introduction to the handbrake: The professional term for the handbrake is auxiliary brake. The handbrake is used to stabilize the vehicle after it has stopped, preventing accidents caused by rolling on sloping roads. Common handbrakes are usually placed at the right hand side of the driver for easy access, but some models have the parking brake installed on the side of the brake pedal. Introduction to the footbrake: The footbrake refers to the parking footbrake, a type of parking brake operated by the foot, commonly found in automatic transmission models. Overview: Braking, also known as stopping, refers to the action of stopping or reducing the speed of a running locomotive, vehicle, or other transportation tools or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, band, or disc on the machine base, which generates a braking torque under external force.

What license is required to drive a small yellow plate vehicle?

Small yellow plate vehicles require a B2 driver's license to operate. Introduction to small yellow plate vehicles: The small yellow plate indicates a self-dumping low-speed truck as stated on the vehicle registration certificate. Introduction to B2 driver's license: The B2 driver's license, commonly known as the large truck driver's license, allows holders to operate heavy and medium-duty trucks, as well as large, heavy, and medium-sized special operation vehicles. It also permits driving vehicles covered by C1, C2, C3, C4, and M class licenses. The full name is motor vehicle driver's license. The current driver's license classification system was established in 2010, comprising 16 categories: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, P. Each license category specifies the types of vehicles that can be legally operated.

How often should a tensioning jack be calibrated?

Tensioning jacks should be calibrated every 6 months. Introduction to tensioning jacks: A tensioning jack is a specialized hydraulic jack used for tensioning prestressed tendons such as steel strands. The tensioning jack must be used in conjunction with a tensioning oil pump, with both the tensioning and retracting power provided by the high-pressure oil from the pump. Depending on their structure, they are categorized into front-clamp jacks and through-hole jacks. Tensioning jacks feature compact structures, stable operation during tensioning, high oil pressure, and substantial tensioning force, making them widely used in prestressed construction projects such as highway bridges, railway bridges, hydroelectric dams, and high-rise buildings. The accuracy of the tensioning force value of a prestressed tensioning jack directly affects project quality and safety. Therefore, calibration to provide accurate and reliable testing data is crucial. Calibration precautions: Appearance and accessories: The main body of the jack and its major components should have nameplates indicating the product name, model, serial number, manufacturer, etc. Jack equipment should be calibrated and used as a matched set; recalibration is required after replacing major components. Indicator: For analog indicators, the dial scale and markings should be clear, with no loose or bent pointer. During force application, the pointer should move smoothly without sticking or jumping. Operational adaptability: The oil pump of the jack should apply and release force steadily, without pressure fluctuations that hinder readings, and without impact or vibration.

What parts need to be replaced after three years of owning a new car?

Within 3 years, it is still considered the new car period, with new vehicle components and good condition. The parts that need replacement within 3 years include the four filters, brake pads, and wiper blades. Four filters: The most common periodic maintenance. (Replace every six months or every 5,000 to 10,000 kilometers.) Brake pads: It is recommended to check them during every maintenance service. The inspection is free, and replacement depends on wear condition. (Every 30,000 to 40,000 kilometers or 2 to 3 years.) Wiper blades: Wiper blades are used frequently. (Replace every year or 20,000 kilometers, but if they don’t affect visibility, replacement may not be necessary.)

What is the reason for the Xin Da Du EFI fault light to illuminate three times?

Xin Da Du EFI fault light illuminating three times indicates an electronic control fault in the engine. Introduction to automobile engines: The automobile engine is the device that provides power for the car, serving as the heart of the vehicle, determining its power, economy, stability, and environmental performance. Depending on the power source, automobile engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others. Common gasoline and diesel engines are both reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston movement and outputting power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, high thermal efficiency, and better economic and emission performance than gasoline engines. Maintenance of automobile engines: Maintain good ventilation in the crankcase. Most gasoline engines today are equipped with a PCV valve, but contaminants from blow-by gases can deposit around the PCV valve, potentially clogging it. Therefore, it is necessary to regularly clean the contaminants around the PCV valve. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. To avoid faults, the oil should be changed periodically based on usage conditions, and the oil level should be kept moderate. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, nitrogen oxides, and other substances from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Therefore, the crankcase should be cleaned regularly to maintain the cleanliness inside the engine.
