The bearings of the military carriage were made of fine iron. The material was strong and had a good shock absorption effect. The two horses and four wheels also greatly increased the buffer of the carriage. It could balance a certain level of stability and safety at high speeds.
The wood of the teak carriage was fine and hard. Even if it was exposed to the elements, the cold of winter, or the heat of summer, the wood would not be crooked or cracked. It had very strong shock absorption and shock resistance, greatly increasing the comfort of the carriage.
The hard places on the walls of the carriage were covered in sheepskin.
There were two layers of fur on the sheep's skin. The outer layer was rough and could resist the sun and rain, but the fur on the inner layer was soft, elastic, firm, and durable. It could reduce shock to a certain extent and avoid bumps and injuries.
