The stand of the experimental sample of the bicycle drive
grabcad
A flat muscular drive mechanism has been developed, including two synchronized cranks L1, L2 (in the experimental sample, the synchronization of the crank movement is carried out by chain transmission) and a pedal element LP pivotally connected to them. With the first crank, the pedal element is connected by a rotational kinematic pair, with the second crank - by a higher kinematic pair (arc or through a roller - by a cylinder-plane pair). The adjustment of the pedal element trajectory is carried out by changing the angle between the cranks.
