Bolted connections are the most important form of connection between mechanical components or different components in a vehicle. The safety of bolted connections directly affects the safety and reliability of the entire equipment or vehicle operation. A variety of bolting forms have emerged today, two of which are described: one is the use of friction linings to increase the friction coefficient of the contact surface; the other is in the form of pin bushings to improve the shear resistance of the bolted joints. These two methods can effectively improve the bearing capacity of the bolt connection, control the size of the joint portion, and reduce the cost.
