The working principle of the brake drum

The working principle of the brake drum is to make the friction lining rub against the inner side of the brake drum through a hydraulic device to achieve the braking effect. The brake drum is mainly composed of brake wheel cylinder, brake shoe, brake drum, friction lining, return spring and other parts. When the brake pedal is stepped on, the piston of the brake master cylinder is pushed to move, and then pressure is generated in the oil circuit. The brake fluid transmits the pressure to the brake drum, so that the friction lining contacts the brake drum, generating friction, and slowing the vehicle Or stop. The brake drum is mostly used to brake the rear wheel and parking brake with relatively small load.

What's the difference between plastic and nylon

Nylon and plastic are both synthetic materials, but there are some key differences between them. Nylon is often used in gears, bushings and plastic bearings because of its low coefficient of friction. It is also widely used in clothing, reinforcement of rubber materials (such as tires), ropes, and plastic parts on vehicles and mechanical equipment. Plastics, by contrast, are a broader category that includes multiple materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and so on, each with its own specific application area.

What's a flange

Flange, also known as flange, is a common mechanical connection component, often used in pipeline engineering and mechanical equipment. It is a disk-shaped metal body with fixed holes distributed around it for connection with other parts or pipes. Flanges are manufactured in accordance with the dimensions and tolerances produced by national standards to ensure that standardised flanges can provide stable performance and adequate safety in a variety of application scenarios.

Hoop type action

The hoop is a common installation and fixing tool whose function is to hold the object tightly in a specific position. Depending on the application scenario, the hoop can be made of different materials, such as metal or plastic. They can be used for a variety of occasions, including building construction, pipeline installation, fixing of power facilities, etc.
