AI Technical Summary

Technical Problem

The fixed rigid connection structure of the front and rear compartments of existing forestry transport equipment cannot adapt to changes in road surface under complex road conditions, resulting in tires being suspended in the air, reduced traction, and uneven stress on the equipment, increasing the risk of rollover.

Method used

The front and rear compartments are connected by an articulated structure. The rotation principle of the articulated structure allows the compartments to swing relative to each other under complex road conditions, keeping the tires in contact with the ground. Flexible adjustment is achieved through steering cylinders and slewing bearings, which disperses stress and enhances structural stability.

Benefits of technology

Maintaining tire contact with the ground in complex road conditions prevents suspension, increases traction, reduces equipment stalling and rollover risks, and enhances the passability and safety of transport equipment.
