Definitions
- the invention relates to a rotor brake device for a hydrodynamic transmission unit with a brake lining and a pressure element designed so that the pressing element presses the brake pad against a rotational element of the hydrodynamic gear unit upon activation of the rotor brake and thus the rotational element can be braked.
- the invention relates to a hydrodynamic transmission unit with a corresponding rotor brake device, wherein the transmission unit has a hydrodynamic coupling and / or a hydrodynamic converter, and at least one mechanical gear stage.
- a hydrodynamic transmission with a rotor brake device and a corresponding rotor brake device are known, for example from DE 4226665 A1.
- the described rotor brake is provided, which in this case is indirectly connected to the secondary shaft of the hydrodynamic transmission component and thus can decelerate and hold the secondary side.
- Rotor brakes are particularly known which can be activated electromagnetically or which are designed as a gear pump with controllable filling.
- a disadvantage of the known rotor brakes is that they cause great additional construction and assembly costs and are relatively expensive, because they are needed only rarely and in a few operating conditions. In addition, they require additional space.
- the object of the invention is to develop a suitable and reliable rotor braking device for a hydrodynamic transmission unit, which is designed simpler and cheaper and which avoids the aforementioned disadvantages.
- the pressing member is a hydraulic cylinder which is at least partially integrated in a channel plate, wherein at least one supply line for controlling the hydraulic cylinder is present, which is at least partially integrated in the channel plate, and wherein the channel plate has further channels, which are for driving and / or supply of other transmission elements serve.
- a hydraulic cylinder as a contact element for the rotor brake offers the enormous advantage that the already existing oil circuit can be used for control. This eliminates the separate and complex electromagnetic control of the rotor brake, as well as the separate cable harness for it. By the hydraulic control, a larger displacement and a greater contact pressure of the brake pad is possible, in particular, the two parameters are independent of the design of the magnet.
- metering or control valves such as solenoid valves, for the various channels, for example, control channels, or sub-circuits may be appropriate.
- the channel plate may be provided with a cover plate which covers and tightly seals channels and supply lines. Due to this multi-part design, the channel plate is easier to manufacture.
- Integration of the hydraulic cylinder into the channel plate is understood to mean that the braking force applied when the brake is activated is picked up by the channel plate, since the pressure element is supported thereon.
- the channel plate serves as a support structure for the brake components. Accordingly, the channel plate must be sufficiently dimensioned and reliably fixed to the transmission housing.
- the rotor brake device can be preassembled on the channel plate and mounted as a unit with the channel plate, which is a great simplification.
- a solenoid valve is preferably present, which controls the supply of hydraulic fluid into the pressure chamber or the pressure therein.
- Hydraulic cylinders are known per se. This has a piston and a housing in which the piston can move back and forth. The hydraulic cylinder is controlled via a pressure chamber into which hydraulic fluid is supplied via the supply line can, so that a pressure on the piston is exerted to move it and apply the contact force. Hydraulic cylinders and solenoid valves are available as standard and standard parts, resulting in lower costs than individually designed and manufactured components.
- the pressing element can act directly or indirectly on one or more force-transmitting intermediate elements, such as levers, connecting parts or the like, on the brake pad.
- force-transmitting intermediate elements such as levers, connecting parts or the like
- the closing principle The rotor brake is not activated when the rotation element is at a standstill. That is, the brake pad is not in contact with the rotary member, the rotor brake is open.
- This principle is particularly suitable for systems in which a pressure for the hydraulic system is built up only during operation by the transmission dynamics.
- the opening principle Here, the rotor brake is closed when the rotation element is stationary, the brake pad is against the rotating element and holds it firmly. If you want to switch to traction, the pressure on the hydraulic cylinder is reduced to move the brake pad away from the rotating element and to open the rotor brake.
- This principle requires a system that can generate pressure in the hydraulic system independently of the transmission dynamics. Further advantageous features of the embodiment according to the invention, which make the rotor brake device even easier and cheaper, can be found in the dependent claims.
- the hydraulic cylinder has a housing which is completely or at least partially formed by the channel plate. That is, the piston is guided in the channel plate and / or the pressure chamber is at least partially formed by the channel plate.

- a support which is part of the hydraulic cylinder and forms at least a part of the housing in which the piston can move back and forth, and which is connected to the channel plate.
- the supply line for controlling the hydraulic cylinder is completely integrated in the channel plate.
- both the supply of the hydraulic fluid and the pressure chamber is arranged on the piston of the hydraulic cylinder in the channel plate. This results in a particularly simple design without too many attachments.
- the brake lining which comes into contact with the rotary element during braking, may preferably be arranged on a lever which is pivotable about a pivot point and which has an engagement point for the hydraulic cylinder.
- the lever may be designed so that the point of attack of the hydraulic cylinder is farther from the fulcrum than the brake pad. Thereby the braking force is increased with respect to the force exerted on the lever by the pressing element.
- the lever may be designed so that the point of attack is located closer to the pivot point than the brake pad. As a result, a larger movement of the brake pad towards the rotational element is possible, as it corresponds to the pure displacement of the piston in the hydraulic cylinder.
- a restoring element in particular a return spring, present, which acts on the lever such that it can act in the opposite direction to the hydraulic cylinder.
- a certain threshold value normally open principle.
- a return element may be present, which is arranged so that it can move the lever in the direction of the rotary member and thereby cause the brake to close.
- a return element may be present, which acts on the piston of the hydraulic cylinder, so that the brake pad is moved away from the rotating element when the pressure in the pressure chamber falls below a certain threshold.
- the return element acts so that the brake pad is moved away from the rotating member when the pressure exceeds a certain threshold.
- the hydraulic cylinder may be designed with a piston on which the brake lining is arranged. The piston presses the brake pad directly onto the rotating element. So a particularly space-saving design is possible.
- the provision of the brake can be realized in an advantageous manner with a hydraulic cylinder which is designed as a double-acting cylinder.
- a hydraulic cylinder which is designed as a double-acting cylinder.
- Such a hydraulic cylinder has a second pressure chamber, which can be filled with hydraulic fluid, so that the piston is moved in the opposite direction.
- the brake can be activated or opened.
- two solenoid valves or a suitable switching valve are used to control in this case.
- Brake lining is generally understood to mean an area which can be brought into contact with the rotating element and is suitable for generating a braking frictional force.
- the material for the brake lining for example, an impregnated fabric of non-magnetic metal or resin-bonded magnetic metal or sintered friction material is particularly suitable.

- the object is achieved by an embodiment according to claim 13, that is, characterized in that a rotor brake device according to the invention is provided.
- the corresponding rotor wheel associated with the rotor brake can be held when no oil is present in the intermediate space, and thus a shift in the mechanical transmission stage is possible.
- the mechanical gear stage may be a reverse gear to reverse the direction of rotation at the same ratio or a mechanical transmission or a combination of both.
- the mechanical gear stage to a neutral position, which is located between two to be switched gear positions.
- the embodiment may be designed such that the rotation element, on which the rotor brake can act, is formed by the rotor wheel on the secondary side of the hydrodynamic coupling or of the hydrodynamic converter.
