Motor vehicle with an engagement device of a gearbox and a parking brake driven by a same actuator

A motor vehicle, comprising:

• a plurality of wheels;
• a propulsion motor configured to provide power output;
• and
• a transmission configured to transmit the power output of the propulsion motor to the wheels, the transmission comprising:
• a drive shaft driven by the power output of the propulsion motor;
• a gearbox, comprising:
• an input shaft;
• an output shaft;
• and
• an engagement device operable to engage a relative gear ratio between the input shaft and the output shaft;
• a clutch selectively controllable to connect the drive shaft to the input shaft;
• a drive assembly comprising a rod coupled to the engagement device and an actuator device configured to translate the rod along a straight axis between a first position, where the rod leads the engagement device to engage the gear ratio, and a second position distinct from the first position;
• and
• a parking brake comprising a first member fixed at one among the input shaft and the output shaft, and a second member movable between a locking position, in which the second member is engageable with the first member to lock the transmission, and a release position, in which the first and second members are spaced apart and the transmission is not locked by the parking brake,
• wherein the drive assembly further comprises a locking mechanism configured to lead the second member into the locking position in response to a translation of the rod into the second position.
