Dual axle trailer suspension

The middle of the Dual axle trailer suspension is fixed on the axle by U-shaped bolts (also called riding bolts), and the roll ears at both ends are hinged on the frame bracket with pins. In this way, the axle is connected with the body through the leaf spring, which plays the role of buffering, vibration reduction and force transmission, with strong rigidity, high load bearing and reliable performance.
