U-shaped bolts AZ9925520230 for dump truck parts

U-bolt of dump truck parts is an important fastener of dump truck. The following is a detailed description of it:

1. Basic definition:

• U-shaped bolt, also known as riding bolt, because the shape is U-shaped and named, both ends of the thread can be combined with the nut, non-standard parts.

2. Shape and structure:

• Shape: mainly semi-circle, square right Angle, triangle, oblique triangle and so on. These different shapes can meet the installation and fixing needs of different parts of the dump truck, for example, semi-circular U-bolts are used more in some places that need to be closely fitted with circular parts, and square right angles are more suitable for square or rectangular parts.

• Structure: composed of a U-shaped rod part and a threaded part at both ends. The rod part is used to surround the fixed parts to provide wrapping support and fixing; The threaded part is used to match with the nut, and by tightening the nut, the U-bolt is tightly fixed in the corresponding part of the dump truck.

3. Function and use:

• In the dump truck, U-bolts are mainly used to connect and fix various parts, such as fixing the plate spring on the shaft or balance shaft, to prevent the plate spring from jumping in the longitudinal or horizontal direction during the vehicle driving, to ensure the stability and comfort of the vehicle.

• It is also used to fix the chassis parts, frame and other key parts of the dump truck, so that the overall structure of the dump truck is more solid and reliable, and can withstand various stresses and impacts generated by the vehicle during loading and driving.

4. Technical standards and specifications:

• Technical standards: Generally need to meet the relevant national standards or industry standards, such as tensile strength, yield strength, hardness and other aspects of the clear requirements to ensure the quality and performance of U-bolts.

• Specifications: The specifications of the U-bolt mainly include the diameter, length and thread specifications of the bolt. The diameter usually ranges from a few millimeters to tens of millimeters, the length is selected according to the specific use scenario and needs, and the thread specifications also have a variety of standards, such as M6, M8, M10, etc., to meet different connection and fixing requirements.

5. Installation and maintenance precautions:

• Installation: Before installation, ensure that the mounting holes of the components to be fixed are correct and both ends of the U-bolts can pass through the mounting holes smoothly. When tightening the nut, use the appropriate tool and tighten it according to the specified torque to avoid too loose or too tight. Too loose may lead to unstable fixing, affecting the normal operation of the dump truck; Too much tightness may damage the bolts or fixed parts.

• Maintenance: Periodically check the fastening of U-bolts and tighten them in time if they are loose. At the same time, pay attention to check whether the surface of the bolt has rust, wear and other conditions, if necessary, timely treatment or replacement, to ensure the performance and service life of the U-bolt.
