Technical Field
The utility model relates to a vehicle turns to technical field, specifically is a transport vehicle turns to function steering axle with wide-angle.
Background
The cost of operating and maintaining the transport vehicle is a major portion of the wear of the tires. The tires of a conventional semitrailer must be replaced every four months, wherein tires of a trailer rigidly suspended on three axles are more worn. Since the rearmost tire slides on the road surface under traction when the vehicle is turning, a large amount of lateral friction (sliding friction) with the ground is caused. In addition, the body structure and the running system are also subject to other complications during steering, which also leads to a greater degree of wear of the tires. Due to friction between the tires and the ground, the maneuverability of the vehicle is degraded during steering, which affects stability. Meanwhile, the service life is reduced along with the reduction of the fatigue resistance of the vehicle; the road surface is thus subjected to greater action and is more susceptible to damage or reduced service life.
