Switching mechanism for manual gearbox, has inertia mass movable in radial direction of inertial lever, where distance between inertia mass and axial middle line is larger when inertia lever is in neutral position

摘要

The mechanism has a guiding pin (38) contacting with a cam groove (39) that is provided in a flat plate designed in a housing (10) perpendicular to an axial middle line of a shaft. A section from the cam groove to the flat plate is designed such that an inertia mass (35) is movable in a radial direction of an inertia lever (30). Distance between the inertia mass and the axial middle line when the inertia lever is in a neutral position is larger than distance between the inertia mass and the axial center line in a case when a regulating step is raised by using a shift-fork.
