How should the metal parts of the wheels be cast?
The outer rim has grooves to facilitate the fitting of the tire.
As for the size and design of the grooves, more experiments need to be done; otherwise, the tires can easily fall off.
Ma Lin's idea is, since we are currently making experimental models of the vehicles, functionality is the priority.
If you're afraid the outer tires will fall off, secure them with screws, although this might cause the rubber to deteriorate more quickly.
The vehicles being made now are ten electric tractors for plowing fields.
They don't need to travel long distances.
The thickness and elasticity of the inner tube have been tested multiple times by Ma Lin before being selected.
The thickness and elasticity of the outer tire have also been tested multiple times.
The middle of the wheel has holes to facilitate inserting and fixing the axle.
Now, processing these metal parts is slightly easier than before.
