Abstract: A transmission device (5) for an electrically drivable vehicle axle (1) includes a transmission input shaft (7), a transmission output shaft (10) connected thereto via gear-wheel pairs (8, 9), and a parking lock device (15). The parking lock device (15) is arranged in a transmission housing (11) and includes an electric actuator (16) for actuating a locking pawl (18) engageable with a parking interlock gear (19) operatively connected to the transmission output shaft (10). The locking pawl and the parking interlock gear (19) are arranged in an interior space (14) of the transmission housing (11) that is acted upon by oil, and the electric actuator (16) is arranged in an oil-free interior space (13) of the transmission housing (11).

Abstract: A parking lock includes a locking pawl (2) and an interlocking element (6) arranged on a connecting bar (5) to a selector lever (4). The end of the connecting bar (5) facing away from the interlocking element (6) is articulatedly connected to the selector lever (4). A hydraulically actuatable actuator (10) includes two pistons (11, 12) provided for disengaging the parking lock. During normal operation, a detent device (13), which is actuatable by an electromagnet (13a), locks the first piston (11) in a piston position corresponding to an engaged condition (P_ein) or a disengaged condition (P_aus). Without requiring activating the electromagnet (13a) to release the detent device (13), the parking lock, during normal operation, is manually disengagable with an emergency disengagement device (15) acting upon the second piston (12) and is manually engagable with an emergency engagement device (16) acting upon the detent device (13).

Abstract: A parking lock for a motor vehicle includes a pivotably mounted locking pawl (20), an interlocking element (60), and a guide rod (40). A spring element (80) preloads the locking pawl (20) in a disengagement direction of the parking lock. A first free end (83) of the spring element (80) is supported directly on a support section (24) of the locking pawl (20) and, during the swiveling of the locking pawl (20), rests against the support section (24) in a stationary manner. A second free end (85) of the spring element (80) is supported directly on a support contour (43) of the guide rod (40) and, during an axial movement of the guide rod (40), slides along the support contour (43). The geometry of the support contour (43) is configured such that the preload force of the spring element (80) does not decrease during the disengagement of the parking lock.

Abstract: A parking lock device for a motor vehicle including a parking interlock gear and a parking pawl. The parking interlock gear has teeth and tooth gaps, wherein each of the teeth has a first and a second deflecting contour that are counter-revolving and radially increasing from a radial indentation toward a respective tooth flank. The parking pawl includes a ratchet tooth. The parking interlock gear is rotatable about an axis of rotation and the parking pawl is rotatable about or translational along a swivel axis parallel to the axis of rotation. The contours slidingly guide the ratchet tooth to catapult over the tooth gaps in a targeted rotational speed range of the parking interlock gear, the targeted rotational speed range being between a minimum limit speed and a maximum limit speed, such that contact is avoided between tooth flanks of the parking pawl and of the parking interlock gear.

The disk-shaped structure has a pair of contact surfaces. Each contact surface of the pair of contact surfaces runs radially and is positioned at a respective axial side of the disk-shaped structure. A profile plane of the driving profile is tilted at an angle with respect to a radial plane of each contact surface of the pair of contact surfaces. A related mounting arrangement is also provided.

Abstract: The invention relates to a device (14) for securing a clamping element against unintentional release, with a disk-shaped structure (15) that is penetrated in an axial manner by a bore hole (16). Thereby, the structure (15) is provided for an inner diameter with a driving profile (17) defined by the bore hole (16), which, in the placement of the structure (15), engages with the bore hole (16) on a radially inner component in a profile provided on the part of such component and thereby establishes a torque-proof coupling of the structure (15) with this component. In addition, the structure (15) is provided, in an axial manner on both sides, with contact surfaces (18, 19) that run in a radial manner. In order to provide a device that can be mounted on a radially inner component in a manner that is as free of backlash as possible and with low expenses, a profile plane (22) of the driving profile (17) is tilted at an angle (?) with respect to radial planes (20, 21) of the contact surfaces (18, 19).

Abstract: A layer system that can be annealed comprises a transparent substrate, preferably a glass substrate, and a first layer sequence which is applied directly to the substrate or to one or more bottom layers that are deposited onto the substrate. The layer sequence includes a substrate-proximal blocking layer, a selective layer and a substrate-distal blocking layer. Also provided is a method for producing a layer system that can be annealed and has a sufficient quality even under critical climatic conditions and/or undefined conditions of the substrate. During the heat treatment (annealing, bending), the color location of the layer system is maintained substantially stable and the color location can be widely varied at a low emissivity of the layer system. For this purpose, a first dielectric intermediate layer is interposed between the substrate-proximal blocking layer and the selective layer and is configured as a substoichiometric gradient layer.

Abstract: A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.
