Problems solved by technology

However, this has the disadvantage that, due to the installation space, a large distance has to be covered to reach the possible installation positions of the blocking drive
Therefore, an overall increased installation space is required, and the mechanical rigidity of the system, especially the mechanical rigidity of the actuating device is reduced

Embodiment Construction

[0064] figure 1 A parking lock device 25 is shown in a partly shown vehicle transmission 2 with a parking lock actuator 1 integrated in a transmission space 34 in a housing 33 . Here a parking lock gear 5 is provided with a gear axis 17 such that the parking lock gear 5 can be moved along the rotational movement 4 . Thus, in this case a plurality of tooth gaps 6 can be positioned relative to the locking projection 3 in such a way that there is a tooth gap position or a tooth-to-tooth position (see figure 2 ). The locking lug 3 is arranged on a pivot lever 20 pivotable about a bearing axis 19 . In the shown state of the parking lock actuator 1, the blocking drive 9 (electric in this case) transmits a torque or maintains it by means of a self-lock, so that the opening actuation force 8 (pointed to the right in the figure) is applied To the actuating device 7, which is designed as an axially displaceable spindle. Thus, the intermediate element 12 , here designed as a rotatin...

Abstract

The invention relates to a parking lock actuator (1) for integration into a vehicle transmission (2), having at least the following components: a locking cam (3) for locking a rotational movement (4) of an associated parking lock gear (5) by means of a form-locking engagement in a tooth space (6) of the associated parking lock gear (5); an actuation means (7) for transmitting an actuation force (8) to the locking cam (3), said actuation means (7) being displaceable between a locked position and an open position; a locking drive (9) for moving the actuation means (7); and an energy accumulator (11) for transmitting the actuation force (8) from the actuation means (7) to the locking cam (3). The parking lock actuator (1) is predominantly characterised in that the actuation means (7) can be moved by the locking drive (9) by means of an intermediate element (12) along a displacement path (10), said intermediate element (12) being freely slidable relative to the locking drive (9) along a predefined intermediate path (13). The proposed parking lock actuator permits a compact construction, so that the parking lock actuator can be integrated into a vehicle transmission with virtually no effect on installation space.

Description

technical field [0001] The invention relates to a parking lock actuator for integration in a vehicle transmission, said parking lock actuator having at least the following components: [0002] - a locking lug for locking the rotational movement of the assigned parking lock gear by means of positive engagement in a tooth gap with the assigned parking lock gear; [0003] - actuating means for transmitting an actuating force to the locking projection, wherein said actuating means is movable between a locked position and an unlocked position; [0004] - a blocking drive for moving the actuating means; and [0005] - An energy accumulator for transmitting an actuation force from the actuation device to the locking lug. Said parking lock actuator is mainly characterized by an actuating means of the blocking drive, said actuating means being movable along a path of travel by means of an intermediate element freely displaceable relative to the locking drive means via a predetermined...
