When it comes to ensuring the safety and reliability of semi-trucks, the braking system plays a pivotal role. Among the critical components of this system are brake shoes and drums, which work in concert to provide effective stopping power and maintain vehicle control. Understanding how these components function and their significance can help truck operators make informed maintenance choices, ultimately leading to safer roads.

Brake fade is a common issue associated with overheating brake drums. This occurs when the brake components become too hot to generate sufficient friction, leading to decreased stopping power. Drivers may notice that they need to press the brake pedal harder or that the vehicle takes longer to stop, which can be dangerous in emergency situations. Preventing brake fade involves recognizing the signs of overheating and allowing the brakes to cool down if they become too hot.

ブレーキドラムは通常、ブレーキシューによって固定されています。ドラムが外れない場合は、軽く叩いてみるか、ドラムリムーバーを使用して取り外すことができます。リムーバーを使用する場合は、ドラムの中央に正しく取り付け、回転させてドラムを引き抜くようにします。

تعمل فرامل الأقراص عن طريق الضغط على أقراص معدنية تُثبت على العجلات، مما يساعد على إبطاء سرعة المقطورة أو إيقافها تماماً. عند الضغط على دواسة الفرامل، يُولِّد السائق ضغطًا هيدروليكيًا يدفع الفرجار (الكاليبر) لضغط البطانة على القرص. ينتج عن هذا الاحتكاك قوة كبح فعالة تسهم في إبطاء أو إيقاف المقطورة.

The primary role of the drum brake anchor is to provide a fixed point against which the brake shoes can press during braking. When the driver applies the brake, hydraulic pressure is applied to the brake shoes, forcing them outward against the inner surface of the rotating drum. The anchor holds one end of the brake shoes in place, allowing the other end to pivot and create the necessary force to generate friction against the drum. This friction is what slows down or stops the vehicle.

Moreover, lubrication aids in the smooth operation of the brake shoes and prevents them from sticking to the drum. If the shoes are unable to retract properly after being applied, it can lead to increased friction, overheating, and rapid wear. This not only compromises braking efficiency but also poses safety risks.
