Structural components of a flatbed trailer: Service brake system: The service brake system of a flatbed trailer is the braking system, which utilizes a hydraulic booster system. It consists of a brake pedal, brake fluid, master cylinder, brake lines, wheel cylinders, and brake assemblies. During braking, pressing the brake pedal activates the master cylinder to send brake fluid to the wheel cylinders, which then act on the brake pads, discs, or drums to force the wheels to slow down, achieving the braking effect. Brake fluid: Brake fluid is the liquid medium that transmits braking pressure in a vehicle's hydraulic braking system. Used in vehicles with hydraulic brake systems, brake fluid (also called brake oil or hydraulic fluid) serves as a force-transmitting medium because liquids are incompressible.

The flatbed trailer looks incredibly sturdy, relying mainly on three major components: The most noticeable is the large flatbed, typically made of reinforced steel plates or patterned aluminum panels with anti-slip grooves on the surface. Hidden underneath is the entire chassis frame, functioning like a human spine, running from the front to the rear of the vehicle, reinforced with cross beams to resist bending. The front section and the trailer turntable deserve special mention—the hitch comes with a safety lock, and the turntable allows the rear section to turn flexibly without twisting. There are tie-down rings at all four corners for securing cargo with steel cables. The axle area is particularly well-designed, featuring a balanced suspension system paired with leaf springs to ensure the wheels handle bumps steadily. The steering and braking systems are linked to the tractor unit, so when you hit the brakes, the trailer stops too. Lastly, don’t forget the reflective panels and safety chains—they’re lifesavers when driving on highways at night.

How Far Can a Car Drive with a Spare Tire?

How far a car can drive with a spare tire depends on the type of spare tire: 1. A full-size spare tire can drive over 100 kilometers; 2. A non-full-size spare tire can drive no more than about 60 kilometers. A spare tire refers to a backup tire for a car, with specifications identical to the original car tire. Precautions for using a spare tire include: 1. Regularly inspect the spare tire; 2. It should not be used for an extended period; 3. The spare tire should not be involved in tire rotation; 4. Avoid storing it with oil products. Spare tires are categorized into full-size spare tires, non-full-size spare tires, and run-flat tires. Depending on the vehicle model, they are typically placed: under the trunk floor, hanging below the rear of the car, or fixed outside the trunk door.

What does unstable car idle speed mean?

Unstable car idle speed refers to the fluctuation of the tachometer when the engine is idling, accompanied by engine shaking. The reasons for unstable car idle speed are: 1. Air, gasoline vapor, or exhaust gas entering the intake manifold, causing the mixture to be too rich or too lean; 2. Ignition module failure, incorrect spark plug gap, spark plug electrode erosion or damage, excessive resistance in high-voltage wires; 3. Injector clogging, fuel filter clogging, fuel pump screen clogging, fuel pressure regulator failure, return pipe clogging, etc., leading to the mixture being too rich or too lean; 4. Failure or damage of the engine intake system's actuators; 5. Excessive carbon deposits on the throttle and surrounding intake passages, changing the cross-sectional area of the air passage, making it impossible for the control unit to precisely control the idle air intake.

What does SN grade engine oil mean?

SN grade engine oil represents a high-quality oil classification. Engine oil grades include: SG, SJ, SL, SM. Its functions are: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purifying; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance. The method for changing car engine oil is: 1. Use a jack to lift the vehicle, locate and loosen the drain plug to release the oil; 2. Remove the oil filter and place a container beneath it; 3.
