Motor for hydraulic pump V401
The motor for the hydraulic pump is integrated into
the mechatronic unit's hydraulic module.
It is actuated by the gearbox control unit subject to
requirements.
The control unit shuts the motor off when the hydraulic
lk
pressure in the system has reached 60 bar, and
switches it on again when the pressure has fallen to
40 bar.

Effects of signal failure
If the motor cannot be actuated, the hydraulic pressure drops and the clutches open independently due to the
pressure plates' spring force.
