Weak self-centering force may be caused by damage to the outer steering gear or the free play adjustment bolt of the steering gear being too tight, which can also prevent the steering from returning to center. Reasons for weak self-centering force after replacing the steering column: The oil reservoir is too dirty, the filter screen is clogged, or the oil level in the reservoir is low. There is a large amount of air in the power steering system. Foreign objects inside the steering system cause the steering pump flow control valve to stick. Insufficient tire pressure, interference or loose connections in the steering column, loose or slipping pump belt, or loose pump installation. Introduction to self-centering force: The aligning torque is the moment generated around the OZ axis when the tire experiences lateral deflection. During circular driving, the aligning torque is one of the main moments that restore the wheels to the straight-ahead position. The aligning torque is produced by the distributed micro lateral reaction forces within the contact patch.

What are the causes of car hose burst?

Car hose burst is caused by: 1. Poor quality or aging of the hose; 2. Excessive pressure in the radiator. Reasons for high radiator pressure include insufficient coolant in the radiator, the fan not fully opening or being damaged and not working, a dirty radiator, excessive scale blockage, thermostat failure, and cylinder gasket damage. If a hose burst is detected, the vehicle must not be started or driven. It is essential to have a professional mechanic inspect, repair, or replace the hose before driving the vehicle again. Observe whether the car hose is swollen. Some hoses may appear significantly larger after prolonged use, with the hose clamp at the connection visibly smaller compared to the swollen hose. In such cases, consider replacing all the car hoses.

How to Calculate Tariffs for Parallel Imported Vehicles?

Tariffs for parallel imported vehicles are calculated under two scenarios: 1. When the tariff rate is reduced to 15%, the calculation method for imported vehicle tariffs is: Total tax rate = 133.4% x consumption tax rate ÷ (1 - consumption tax rate) + 33.4%. 2. When the tariff rate increases to 40%, the total formula for tariff calculation changes to: Total tax rate = 162.4% x consumption tax rate ÷ (1 - consumption tax rate) + 62.4%. Import duty (import-tax) is also known as import tariff. It refers to a type of tariff imposed by the customs of the importing country on goods and items entering the country from abroad. It is the most significant type of tariff. Import duty is levied when foreign goods enter the customs territory or national border, or when foreign goods are transported from free ports, free trade zones, or bonded warehouses to the domestic market for sale and undergo customs clearance procedures.

What does FM mean in a car?

FM in a car refers to the frequency modulation band in the car audio system's radio function. It represents the technology used by radio stations to transmit signals and the standard received by the receiving equipment (radio). After pressing the button, you can listen to the radio on the corresponding band, which represents the technology used by radio stations to transmit signals and the standard received by the receiving equipment (radio). For example, in wireless TV signals, the image uses amplitude modulation, while the sound uses frequency modulation. An FM radio receives FM station signals through an antenna, which are then tuned, amplified, and demodulated by the circuit to separate the audio signal. This signal is then amplified at low frequencies and output through the speaker to produce sound. FM components: The car audio system consists of five parts: the antenna, receiving device, speaker correction, audible frequency amplification, and speaker system. FM function: The antenna is used to receive the broadcast waves transmitted by radio stations and sends them to the radio frequency modulation device via a high-frequency cable. The receiving device selectively picks up the high-frequency electromagnetic waves transmitted by the station and demodulates them into audio electrical signals.
