The device includes at least one first auxiliary brake (4) of a first type and at least one second auxiliary brake (4, 6) of a second type that is different from the first type. The second auxiliary brake (4, 6) can take the form of a retarder (4, 6). A control system (10, 17) is provided for controlling or regulating the auxiliary brake. Information is stored in the control system regarding characteristics of the respective auxiliary brake (4, 6) and at least one predefined limit value for maximally permitted auxiliary brake torque. The control system (10, 17) is designed such that, if the limit value is exceeded or if a request is made for the brake force from the auxiliary brakes (4, 6) to be moderated, then this is done by turning down or moderating, in the first place, the brake torque of the retarder (6).

摘要： The present invention is directed to a retarder control system for protection against transmission overspeed. The system operates in conjunction with a rotatable input member and an output member that is rotatable relative to the input member. A torque transfer device is operatively connected between the relatively rotatable input and output members. Specifically, a piston assembly is operated by an input control chamber that selectively receives pressurized hydraulic fluid which effects translation of the piston assembly to actuate the torque transfer device and thereby effect a driving connection between the relatively rotatable input and output members. The present system is adapted to control a hydrodynamic retarder assembly having a work cavity to receive hydraulic fluid. The retarder input valve assembly is supported from one of the relatively rotatable members selectively to deliver pressurized hydraulic fluid from the input control chamber to the retarder cavity. In order to achieve overspeed protection the retarder input valve opens in response to a predetermined angular velocity of the relatively rotatable member on which the retarder input valve assembly is supported. In a variation of the retarder control system explained above, a dump valve assembly is provided which opens selectively to release pressurized hydraulic fluid from the work cavity of said retarder in response to the pressure of the hydraulic fluid within said retarder work cavity.

摘要： The hydraulic retarder control system comprises pressure reducing valves which can switch the pressure of the air to be supplied from a pressure air source 4 to an air/liquid conversion device 25 at least to a low pressure, an intermediate pressure and a high pressure, or a proportional electromagnetic valve 110 which can reduce and adjust the pressure of the air in a stageless manner, and running speed detect devices 100, 111 which detect the fact that the running speed of a vehicle is equal to or slower than a given running speed. When there is given a detect signal by the running speed detect devices 100, 111, then the pressure reducing valves 32, 95 or the proportional electromagnetic valve 110 are or is switched over to a pressure higher than a set pressure for running speeds exceeding the given running speed, so that the high pressure air from the pressure air source 4 can be supplied to the air/liquid conversion device 25.

摘要： The invention relates to a process for the actuation of an hydrodynamic retarder brake for motor vehicles, which is controlled by an electrohydraulic valve system. The rotational velocity of some part of the drive system (or an average of a plurality thereof) is indicated by a continuously generated electrical signal. When the throttle is released, or the brake pedal, having been depressed is then released, the vehicle velocity at that moment is stored as a reference signal in a memory. If the actual velocity thereafter exceeds the stored value, the hydrodynamic retarder is actuated. The momentary velocity of the vehicle is thereafter continuously compared with the stored reference velocity, and the retarder controlled accordingly. Rapidly applied retarder action is realized by controlling the same using PD control.

摘要： A drive train has a hydrodynamic retarder including a rotating bladed rotor and bladed stator, forming a working chamber for hydrodynamic transmission of power from rotor to stator, a power input feeding drive power to the retarder, and a synchronized separating clutch connected between power input and rotor. The clutch has two clutch halves, friction elements contacting each other and mechanical blocking elements. The friction elements equalize rotational speed between clutch halves, and the blocking elements form-lockingly connect the clutch halves. The clutch has an actuator displaceable along a displacement travel, over a first distance bringing the friction elements into mutual contact, and a second distance adjoining the first distance to synchronize the friction elements and rotational speed for locking with the blocking elements. At least one displacement sensor directly or indirectly detects displacement travel by the actuator and/or position of the actuator on the displacement travel.
