A rubber brake diaphragm from Ningbo Qiaoshi Rubber & Plastics is a key component in the air chamber of truck braking systems. It functions when the vehicle is braking and generating about 0.7 MPa (101 psi). The pressure in the diaphragm pushes the wheel hub in the brake pad forward, resulting in vehicle braking. The diaphragm lifetime is more than 2 million times. The center of the device includes fabric; A90 0.62 to 0.80 mm (0.02 to 0.03 in) and thicker fabric can be used. The unit has a performance at -55°C (-67°F) of 20 s 100% rebound. Depth can be 85 mm (3.3 in) with a slope of 2-5°. The customer’s requirement is a slope of 7-9° and depth of 80 mm (3.1 in). The diaphragm achieves greater air storage volume and braking effect compared to current devices. Male-female type facing diaphragms can also be produced.
