ABSTRACT:
The invention relates to a parking brake system for transmissions of motor vehicle, especially for an automatic transmission and an automated selector transmission, having one parking brake for blocking or releasing the transmission according to actuation signals of a control device, especially by a pawl engaging and disengaging in a parking brake gear connected with the output of the transmission, an electric operative connection between the control device in the interior of the motor vehicle and the parking brake, a spring accumulator (9) for actuating the parking brake and a pressure-controlled release device of the parking brake. It is proposed to load the release device (10) when releasing the parking brake with a negative pressure independent of the transmission and which is preferably taken from the suction system (15) of the internal combustion engine of the motor vehicle or from a negative pressure brake force booster of the motor vehicle.
