In a drive arrangement of a motor vehicle, a hydrodynamic fluid clutch is inserted into the torque transmission between a prime mover and a manually shiftable gearbox, and in order to obtain a parking brake function by engaging a gear, the fluid clutch is bypassed by a positive stationary clutch operating by means of centrifugal bodies as a function of the speed, when the prime mover and the turbine wheel of the fluid clutch are at a standstill. A rocker lever pivoted on the turbine wheel by its one lever end is used as respective centrifugal body, which is connected to positive clutch devices and can be brought by means of an engaging spring acting counter to the centrifugal force into an engaged position in which the clutch devices engage with corresponding clutch devices of that clutch half of the stationary clutch connected to the pump impeller. In order to reliably bring about the positive engagement of the stationary clutch, the rocker lever is kinematically connected by deflection devices to a clutch sliding sleeve supported on the turbine wheel so that it is rotationally fixed and axially displaceable. The clutch devices of that clutch half of the stationary clutch connected to the pump impeller contain a clutch gear rim, which can be brought into engagement with a corresponding clutch gear rim of the clutch sliding sleeve.
