Abstract
An internal shift control mechanism is provided for a motor vehicle gearbox that includes, but is not limited to a fork member for engaging and displacing a synchronizer sleeve of the gearbox in an axial direction between a neutral position and at least one active position, a carriage supporting the fork member , displaceably guided in the axial direction, a shifter axle having an axis of rotation which extends transversally with respect to the displacement direction of the carriage and carrying a shift arm which engages a shift gate formed on the carriage . In the active position a tangent at a contact point between the shift arm and the shift gate is perpendicular to a radius extending from the axis to the contact point.

An internal shift control mechanism for a motor vehicle gearbox, comprising:
- a fork member adapted to engage and displace a synchronizer sleeve of the motor vehicle gearbox in an axial direction between a neutral position and an active position;
- a carriage adapted to support the fork member and displaceably guided in the axial direction;
- and
- a shifter axle having an axis of rotation that extends transversally with respect to a displacement direction of the carriage and carrying a shift arm that engages a shift gate formed on the carriage,
- wherein in the active position a tangent at a contact point between the shift arm and the shift gate is substantially perpendicular to a radius extending from an axis to the contact point.
