Description

1 TARIFF EMERGENCY BRAKE BELLOWS FOR HEAVY VEHICLES Technical Field to Which the Invention Relates The invention relates to service braking and parking in air brake systems used in heavy-duty vehicles. and / or emergency braking is related to emergency brake bellows that provide both emergency braking and emergency braking. 5 Prior knowledge of the art related to the invention. Emergency brakes, especially in pneumatic brake systems, serve as both service brakes in heavy vehicles. It is commonly used to provide parking / emergency braking functions. A traditional The emergency brake bellows consist of a service brake chamber and an emergency brake chamber, and these chambers are located between them. They are separated by a part called a service brake chamber. The service brake chamber is a diaphragm into which pressure is applied. While pneumatically operated by air, the emergency brake compartment is for parking and emergency braking. It is operated by a large helical compression spring that provides mechanical force. In standard designs, the emergency spring relieves the pressure in the emergency chamber during normal vehicle operation. It is kept in a compressed state with air. When the compressed air is released, it is stored in the spring. Energy is transferred to the brakes via a push rod. This facilitates maintenance procedures. 15 For this purpose, most emergency brake bellows mechanically compress and secure the spring during maintenance. It includes a manual cocking bolt mechanism or cocking system. In conventional technology, this is commonly found in heavy vehicles such as trucks, tractors, trailers, and buses. The emergency brake bellows used are mostly manufactured from high-pressure aluminum casting. It has a piece of aratas. 20 The internal structure of these parts, which are produced using the high-pressure aluminum casting (HPDC) method Voids (porosities) can form in the casting. These voids are particularly critical for sealing. In brake bellows, which are of significant importance, performance losses and failures can occur. These problems can occur. Cracks, surface defects, and mold parting marks can appear on the surface after casting. Such defects are frequently encountered. Machining the parts is time-consuming and requires additional labor. 25 This leads to increased costs. The surface coating of the aluminum frame is different from the other sheet metal used in the brake bellows. This requires coating methods that are incompatible with the components; this results in a lack of homogeneity across the entire product. This reveals the problem of lack of corrosion resistance. For all these reasons, aluminum The production process for cast iron furniture is complex, costly, and demanding in terms of quality. 2 These types of situations fall short of meeting some of the requirements of the automotive standard. It remains. In conclusion, all the problems mentioned above make innovation in the relevant field imperative. has brought. Purposes and Brief Description of the Invention 5 The purpose of the invention is to correct cracks, surface defects, and mold separation that occur in parts after casting. to prevent defects such as marks that arise depending on the processing of the parts to reduce time loss and additional labor costs and in the surface coating of aluminum frame This eliminates the need for coating methods that are incompatible with other sheet metal parts of the brake bellows. The aim is to ensure homogeneous corrosion resistance throughout the product by removing 10 particles. Accordingly, the present invention is a product manufactured from steel sheet by deep drawing. They recommend using an emergency brake bellows with a built-in air suspension system.
