Private cars cannot be equipped with bulletproof glass, as the glass seals of ordinary private vehicles cannot bear the weight and thickness of bulletproof glass. Bulletproof glass is made by bonding multiple layers of glass or high-strength organic panels together with transparent laminated materials, consisting of the following three-layer structure: Load-bearing layer: This layer withstands impact and is typically made of thick, high-strength glass that can damage or deform bullets, preventing them from continuing forward. Transition layer: Usually made of organic bonding materials with strong adhesion and good light resistance, this layer absorbs part of the impact energy and alters the bullet's trajectory. A very sturdy and transparent chemical film is sandwiched between the laminated glass, which not only effectively prevents gunfire but also offers resistance to surge impact, explosion, shock, and remains crack-free after impact. Safety protection layer: Made of high-strength glass or high-strength transparent organic materials, this layer has excellent elasticity and toughness, absorbing most of the impact energy and ensuring bullets cannot penetrate it.

What are the reasons for the ABS light in a Skoda being on?

There are various states in which the ABS light may illuminate, with different causes and solutions for each state, as detailed below: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed and the wheel's slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal quality due to loose connections between system wires or poor contact in the ABS relay, leading to system failure. Solution: Check the wire connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates, but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wire connector; ABS computer malfunction. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer calculates a significant difference between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the sticker near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch. If the ABS warning light is on, it is advisable not to continue driving. The illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

What is an Automotive Brake?

An automotive brake refers to the component that generates a force (braking force) to resist the movement or tendency of movement of a vehicle, including the retarder in the auxiliary braking system. It is the braking device of a car, and almost all brakes used in automobiles are friction-based, which can be divided into two main types: drum brakes and disc brakes. Principle of Drum Brakes: Inside the brake drum, hydraulic pressure acts on the pistons of the brake wheel cylinder, which push the curved brake shoes outward. Alternatively, the friction material riveted to the brake shoes presses against the inner surface of the brake drum, slowing down the rotation of the brake drum and the axle to achieve braking. Working Principle of Disc Brakes: Hydraulic oil is used to push the brake pads against the brake disc through the cylinder, generating friction to achieve braking. Disc brakes installed on high-speed shafts come in two specifications for braking torque: 10,000 N·m and 12,500 N·m. The diameter of the brake disc is uniformly 800 mm. Each set of brakes has four cylinders controlled by a single hydraulic system. Its features include high braking torque, excellent heat dissipation, adjustable oil pressure, and the ability to achieve stepless changes in braking torque during operation. The retarder is used as an auxiliary device to the braking system. For vehicles frequently driven in mountainous or hilly areas, it helps to continuously reduce or maintain a stable speed during long descents, thereby reducing or relieving the load on the service brake. The differences between drum brakes and disc brakes lie in braking force, heat dissipation performance, drainage capability, and structural design. Braking refers to the act of stopping a moving vehicle, and the brake is the component in the braking system that generates resistance to the vehicle's movement. Currently, friction brakes are universally used in automobiles, which generate braking torque through friction between stationary and rotating components. These are further divided into disc brakes and drum brakes. Specific differences are as follows: Difference in Braking Force: In terms of braking force, drum brakes far exceed disc brakes. This is not because drum brake technology is more advanced but due to its inherent structural characteristics. In a drum brake system, there is a drum-shaped metal object, which is the core component of drum brakes, hence the name. Difference in Heat Dissipation Performance: Drum brakes operate in an enclosed space, leading to poor heat dissipation. During braking, a significant amount of heat accumulates, causing complex deformations in the brake shoes and drum under high temperatures. This can lead to brake fade and vibration, reducing braking efficiency. Difference in Drainage Capability: Drainage is another advantage of disc brakes over drum brakes. When water enters the braking system, its impact on braking performance is evident. If the water cannot be drained promptly, braking performance will significantly decline. Structurally, the enclosed design of drum brakes is clearly less conducive to drainage compared to disc brakes. Difference in Structure: Disc brakes have a compact and simple structure, while drum brakes are relatively more complex. However, drum brakes can achieve the same braking force with a much smaller diameter than disc brakes. Difference in Heat Dissipation Effect: Disc brakes have exposed brake shoes, resulting in better heat dissipation and more stable braking performance. In contrast, drum brakes have brake linings inside the drum, making heat dissipation difficult. Prolonged braking can cause the braking force to diminish as heat increases.
