   A friction motor is a simple mechanism to propel toy cars, trucks, trains, action figures and similar toys. The motor consists of a large flywheel which is connected to the drive wheels of the toy via a gear train with very low gear ratio, so that the flywheel revolves faster. The flywheel's axis is perpendicular to the direction in which the ...

7. Four-bar linkage - Wikipedia

   en.wikipedia.org/wiki/Four-bar_linkage

   Four-bar linkage. In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed- chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar ...
