Jiaozuo brake

The disc brake depends on your coupling type. If your coupling is a disc type, now it is indeed common to use YWZ series normally closed hydraulic block brakes. If your coupling is drum type, you should use the corresponding drum type normally closed hydraulic brake instead. Performance characteristics of the disc brake: compared with the drum brake, the working surface of the disc brake is flat and has heat transfer on both sides. The disc is easy to be cold cut when rotating, and is not prone to large deformation. The braking efficiency is stable. After a long time of use, the brake disc has enhanced its braking effect due to high temperature expansion; The drum brake has a single side heat transfer and a large temperature difference between the inside and outside, which leads to the brake drum being prone to deformation. At the same time, after prolonged braking, the brake drum expands due to its height, and the braking efficiency is weakened. In addition, the disc brake is simple in structure, convenient in maintenance, and easy to realize automatic adjustment of brake clearance. Working principle of ST3SH closed oil cylinder actual drawing disc brake: disc brake is mainly composed of brake disc, oil cylinder (air chamber), brake caliper, oil (air) pipe and other components, and hydraulic (air) power source. The disc brake is made of the end face of the rotating brake disc as the friction pair. The fixed support is equipped with a brake block composed of friction materials and its metal bottom plate. These brake blocks and their tensioning devices are installed in the clamping clamp shaped supports on both sides of the brake disc, called brake calipers. The brake disc is made of alloy steel and fixed to the wheels, rotating with the wheels. The oil cylinder (air chamber) is fixed on the bottom plate of the brake and does not move. The two friction plates on the brake caliper are installed on both sides of the brake disc. The piston of the oil cylinder (air chamber) is subjected to hydraulic (air) pressure from the oil (air) pipe, pushing the friction plate towards the brake disc for frictional braking, just like clamping a rotating plate with pliers, forcing the moving mechanism to stop moving. Advantages of embedded disc brake: simple structure, convenient installation, not easy to damage, pressure resistant, anti falling and anti knocking, long service life, generally only need to replace the brake pad, easy and simple to replace, using the magnet effect. After sales of Z9 with black background and white lettering: Our company promises a shelf life of one year. If any defects occur during this period, they will be replaced free of charge. Generally, the shell has been used for more than 10 years without any problems, so during use, only the brake pads need to be replaced, providing a good platform for customers to use in the future. Principle of normally closed brake: The embedded disc type normally closed pneumatic brake is different from the normally open brake in that the normally open brake is a ventilated holding brake, which means a ventilated brake. As soon as the brake is ventilated, the clamps on both sides are clamped. The normally closed brake, as shown in the figure, is always in a clamped state and released after being aerated. Therefore, in normal conditions, the normally closed brake is always in a braking state. Normally closed brake spring applies force to brake, and pneumatic drive releases. Advantages of disc brake: simple structure, easy installation, not easy to damage, resistant to pressure, falling and knocking, long service life, generally only need to replace the brake pad, easy and convenient replacement, using the magnet effect
