摘要： The invention relates to an actuator device (1) for actuating a locking mechanism, in particular for actuating a parking break device of a drive train of a motor vehicle, which is embodied with an automatic gearbox. The actuator device comprises a piston unit (4), a locking device and an electromagnetic actuating device (6) which is used to actuate a release element (7) which deactivates the locking device (5). An emergency release mechanism (14) is actively connected to the piston unit (4) enabling the piston unit (4) to be placed in an axial position which is equivalent to the open state of the locking mechanism. According to the invention, the locking device (5), the piston unit (4) and the release element (7) cooperate with each other in such a manner that when the locking mechanism is open and when the electromagnetic actuating device (6) is not fed with electric energy and when the locking mechanism is closed and when a fluid pressure is applied to the piston unit (4), an active force component, which is smaller than the releasing force of the locking mechanism, engages with the piston unit (4) in the opening direction of the locking mechanism and the locking mechanism remains in the current controlled state. The emergency release mechanism (15) enables the locking device (5) to be deactivated.

摘要： The inventive parking brake system (1) is used for the motor vehicle drive train provided with an automatic gearbox. The inventive system comprises an actuator (2) and a locking mechanism (3) actuatable thereby. The drive train output is maintained in such a way that it is not rotatable by the locking mechanism (3) when it is closed state and is rotatable when said locking mechanism (3) is in open state. In the normal operating mode of the vehicle, the locking mechanism (3) is applied to a spring device (6) by the action of a fluid on the piston unit (5) of the actuator (2). Said spring device (6) is connected to the piston unit (5) when the locking mechanism (3) is in the closed state, and is maintained in the open state by a latching device (8), which is controllable by an electromagnetic actuator (7) and fixes the piston unit (5) in the activated state in an axial position (A) equivalent to the open state of the locking mechanism (3). The latching device (8) is deactivatable by the electromagnetic actuator (7). The locking mechanism (3) is closable by an emergency locking mechanism (9) and openable by an emergency release mechanism (10). Said emergency locking mechanism (9) and the emergency release mechanism (10) are actuatable by a common action mechanism (11) in such a way that manual actuation thereof in the same direction make it possible to alternately open or close the locking mechanism (3).

摘要： The invention relates to a control valve arrangement for controlling a start coupling of an automatic gearbox, comprising a clutch control valve (3, 37, 41, 48, 49) for controlling at least one clutch actuating device (4, 40), which during normal operation of the gearbox converts a supply pressure input (P_V1, P_V2) into a clutch actuation pressure (P_K, P_K1, P_K2) according a pre-control pressure (P_VST, P_VST1, P_VST2) or an electric pre-control signal (S) in order to control the clutch actuation device (4, 40). In order to ensure emergency operation of the gearbox, an activating pressure (P_A) can be supplied to the clutch control valve (3, 37, 41, 48, 49) or directly to the clutch activation device (4, 40) in the event of discontinuation of the pre-control pressure (P_VST, P_VST1, P_VST2) or pre-control signal (S) according to the engine and gearbox output speed, whereupon the clutch actuation device (4,40) is maintained in a closed position as long as the above-mentioned speed remains above a predetermined limit.

摘要： The invention relates to a proportional pressure control valve comprising a magnet part and a valve part, whereby the valve part is provided with: an admission opening for the admission volume flow; a first discharge opening for the filling volume flow; a second discharge opening for the tank volume flow; a ball seat, a flat seat provided with an opening; a closing part for controlling the flow rate through the opening of the flat seat, and; a stream diverter that is placed between the ball seat and the flat seat. The admission opening (6) for the admission volume flow is formed on the front end (10) of the valve part, said end facing away from the magnet part, while being coaxial to the longitudinal axis thereof, and the discharge openings (7) for the filling volume flow are formed on the sidewall of the valve part while being radial to the longitudinal axis thereof so that fluid particles flowing from the admission opening to the discharge opening are subjected to a diversion of no greater than 90°. The axial distance of the stream diverter (5') from the ball seat (4), and the diameter, the wall thickness and the design of the stream diverter are selected in such a manner that after the fluid particles flow through the ball seat to and through the stream diverter, they are subjected to a diversion of less than 30°.

摘要： The invention relates to a proportional pressure control valve comprising a valve part (1) having inlet and outlet openings (4) and at least one closing means (2) for controlling an orifice (5). The hydraulically effective cross-section of the valve part (1) is determined by the size and shape of the inlet opening (4). The axial longitudinal axis of the inlet opening (4) is perpendicular to the longitudinal axis of the closing means (2). The exertion of force that is promoted thereby on the closing means (2) advantageously affects the quality of the valve function, especially at low temperatures.

摘要： A hydraulic transmission unit comprises at least one pressure regulation valve (1) and a pilot control valve (2) which is connected to the pressure regulation valve (1) by a pilot control line (35). A pre-filling valve (3, 303) sets a pre-filling pressure (p—3) to avoid draining of a clutch (20) and the lines (231, 331) connected to the clutch (20) in an operating condition in which the clutch (20) is not actuated. To avoid draining when the clutch when in the operating condition, the pilot control line (35) is also connected to at least one line (236, 238, 336, 338) which is pressurized with a second pre-filling pressure (p—3).

摘要： The invention relates to a method for operating a transmission device (10) of a vehicle drivetrain having a plurality of frictional switching elements (A, C to E) and at least one interlocked switching element (B) for implementing various ratios (1 to R). In the neutral operating mode of the transmission device (10), and when an operating mode distribution of the vehicle drivetrain is present for which the at least one interlocked switching element (B) is to be transitioned from an opened to a closed operating mode upon a request for producing the power flow in the transmission device (10), a differential speed in the region of the interlocked switching element (B) is determined by releasing the transmission capabilities of at least two frictional switching elements (A, C) that are to be closed for producing the power flow, wherein a drive torque of a drive machine (9) is adjusted to a level leading to the differential speed in the range of the interlocked switching element (B) within a predefined differential speed range, within which the interlocked switching element (B) at least approximately comprises a synchronous state and can be closed.
