MECHANISM FOR THE TWO-WAY CONVERSION BETWEEN A ROTATIONAL MOVEMENT AND A RECIPROCATING TRANSLATIONAL MOVEMENT, MECHANICAL SYSTEM AND VEHICLE

摘要

The invention relates to a mechanism (10) for the two-way conversion between a rotational movement and a reciprocating translational movement. The mechanism (10) comprises a device (20) pivoting about a main axis (X20) and a device (30) sliding along an axis of translation (Y30) orthogonal to the main axis. The mechanism (10) comprises at once: a connecting rod (40) pivoting, on the one hand, about a first axis (X40) parallel to the main axis and secured to the pivoting device (20) with a constant distance-between-centres (E40) between this first axis (X40) and the main axis and, on the other hand, about a second axis parallel to the main axis and secured to the sliding device (30), with the same distance-between-centres (E40) that is constant between the first axis and the second axis; and a gearing (50) comprising two toothed assemblies (60, 70). The first toothed assembly (60) is secured to the pivoting device (20), centred on the first axis and has a first base diameter equal to twice the distance-between-centres. The second toothed assembly (70) is secured to the sliding device (30), centred on the second axis and has a second base diameter equal to twice the first base diameter. The invention also relates to a mechanical system and to a vehicle.
