[0016] Figure 2 This is an overall structural diagram of a suspension bracket proposed in this utility model;
[0017] Figure 3 This is a side view of a suspension bracket proposed in this utility model. Detailed Implementation
[0018] refer to Figure 1-3This utility model proposes a suspension bracket, which consists of a suspension body 3 for connecting the main beam 1 and the engine support beam 2, a first mounting component, and a second mounting component. The suspension body 3, as the core load-bearing structure, is designed to fully integrate the principles of high efficiency, low cost, aesthetic appearance, and reliability in casting processes. It also comprehensively considers the characteristics of casting solidification and product stress. Through the rational design of the connecting ribs and plate structure, it effectively eliminates thick, hot spots, improves solidification and feeding, and reduces internal defects. Compared with traditional structural components, it achieves excellent performance with a 35% weight reduction, a 15% cost reduction, and a 10% increase in safety. Furthermore, it is adaptable to various casting processes, meeting the optional use requirements of medium and heavy-duty trucks.
[0019] The first mounting component is mounted on the suspension body 3 and is mainly used to achieve a fixed connection with the main beam 1. It includes multiple main beam mounting holes 31 formed on the suspension body 3, and the main beam 1 has first mounting holes that can be adapted to the main beam mounting holes 31. These main beam mounting holes 31 are arranged in an array along the length of the suspension body 3. This design not only ensures the stability of the connection between the main beam 1 and the suspension body 3, but also fully considers the force flow path, enabling the force to be evenly distributed and transmitted, avoiding local stress concentration. First bolts can be installed between the main beam mounting holes 31 and the first mounting holes to firmly fix the main beam 1 to the suspension body 3. Some of the main beam mounting holes 31 can also be shared for the installation of nearby after-processor brackets, further saving assembly space and achieving functional integration.
[0020] The second mounting component is also mounted on the suspension body 3 and is responsible for connecting and assembling with the engine support beam 2. It includes multiple fixing bolt mounting holes 32 on the suspension body 3, and the engine support beam 2 has second mounting holes that can be adapted to the fixing bolt mounting holes 32. The fixing bolt mounting holes 32 are distributed at one end of the suspension body 3. This layout is an optimized design based on the installation position and stress conditions of the engine support beam 2, ensuring a stable and reliable connection between the engine support beam 2 and the suspension body 3. A second bolt can be installed between the fixing bolt mounting holes 32 and the second mounting holes to securely connect the engine support beam 2 and the suspension body 3. This ensures that the vibrations and forces generated by the engine during operation can be effectively transmitted to the suspension body 3 and then distributed throughout the vehicle structure.
[0021] The suspension body 3 also has four cab mounting holes 33, arranged in a rectangular pattern at the other end of the suspension body 3. This rectangular arrangement ensures more even stress distribution on the cab after installation, improving the stability of the cab installation. The cab mounting holes 33 can be connected to the cab via a third bolt, achieving a reliable connection between the suspension body 3 and the cab. This also demonstrates the multi-functional integration of this suspension bracket, reducing the cost and space required for separately designed cab connection components.
[0022] The suspension body 3 has two coaxially arranged pin mounting holes 5, which are through holes penetrating the suspension body 3. A pin for connecting the leaf spring can be installed between the two pin mounting holes 5. This through-hole design facilitates the installation and removal of the pin, improving assembly efficiency. Simultaneously, the suspension body 3 also has a limiting bolt mounting hole 4 that abuts against one of the pin mounting holes 5. The axis of the limiting bolt mounting hole 4 is perpendicular to the axis of the pin mounting hole 5. The limiting bolt mounting hole 4 has a threaded structure. The fourth bolt, through threaded engagement, presses against the side of the pin, thereby locking the pin in the pin mounting hole 5. This effectively prevents the pin from rotating or sliding axially during use, ensuring the reliability and stability of the leaf spring connection and guaranteeing the safety of the entire vehicle during driving.
