Steel disc 3D model

Disk and bus The wheel significantly reduces the energy costs for moving the load along a relatively flat surface. When using the wheel, the work is performed against the frictional force of the rolling, which under artificial conditions is substantially less than the sliding friction force.

The basic kinematic and dynamic relationships between different parts of the wheel are derived from considering it as a solid, and are determined on the basis of geometric properties, initial conditions, operating conditions and other. The wheel is considered the simplest mechanism when it is planted on a fixed or rotating axis that passes through its center. Often, the wheel is installed to provide movement, in which case it is part of the vehicle, providing traffic with great efficiency. If the axle is connected to two wheels, then the wheels rotate as if they were one body.

The wheel axle is one of the six simplest mechanisms. It allows you to get a mechanical advantage, by increasing the applied force due to the torque. The bottom line is that the mechanism engages with the ground only on the sole of the wheels, they act as a supporting system for the vehicle, which reduces energy losses, despite such drawbacks as the elasticity of the wheels and the loss of torque in the bearings. When using wheels for various vehicles, it is also necessary to provide the necessary adhesion to the ground, which can be achieved by using corrugated wheels.
