    Abstract

    A gear assembly for a motor vehicle comprising at least one shaft, at least one gear component arranged on the shaft, at least one engagement component which is engaged with the gear component or can be brought into engagement with the gear component, and at least one damping element. The damping element is arranged in an operative manner between the gear component and the engagement component and/or between the gear component and the shaft, and wherein the damping element is produced at least in part from amorphous metal.

    Claims

    1. A gear assembly for a motor vehicle comprising: at least one shaft: at least one gear component, wherein the gear component is arranged on the shaft; at least one engagement component which is engaged with the gear component or can be brought into engagement with the gear component; and at least one damping element, wherein the damping element is arranged in an operative manner between the gear component and the engagement component and/or between the gear component and the shaft, wherein the damping element is produced at least in part from amorphous metal.

    2. The gear assembly according to claim 1,wherein the damping element is designed as a separate component, integrally with the gear component and/or integrally with the engagement component.

    3. The gear assembly according to claim 1, further including a parking lock mechanism, wherein the parking lock mechanism comprises a parking lock gear which is fixedly arranged on a gear output shaft, and a parking lock pawl which is pivotably arranged on a fixed axle and can be brought into a locking position with the parking lock gear, wherein the damping element is arranged in an operative manner between the parking lock pawl and the parking lock gear and/or between the parking lock gear and the gear output shaft.

    4. The gear assembly according to claim 3, wherein the damping element is designed as a separate component, integrally with the parking lock gear and/or integrally with the parking lock pawl.

    DESCRIPTION OF THE INVENTION

    [0022] FIG. 1 shows schematically a parking lock mechanism 6. The parking lock mechanism 6 is part of a gear assembly 1 of a motor vehicle according to the invention.

    [0023] The gear assembly 1 comprises a shaft 2, a gear component 3, an engagement component 4 and two damping elements 5, 5′.

    [0024] The shaft 2 shown in FIG. 1 depicts a gear output shaft 8 of the gear assembly 1. The parking lock mechanism 6 has a parking lock gear 7 fixedly arranged on the gear output shaft 8 and a parking lock pawl 9. In this context, the parking lock gear 7 represents the gear component 3 and the parking lock pawl 9 the engagement component 4. The parking lock gear 7 is arranged fixedly, i.e. non-rotatably and axially fixedly, on the gear output shaft 8. The parking lock pawl 9 is mounted pivotably on an axle fixed to a gear housing and can be brought into a locking position with the parking lock gear 7 during activation of the parking lock mechanism 6. If the parking lock pawl 9 is brought into a locking position with the parking lock gear 7, the gear output shaft 8 is locked and cannot be rotated further. One of the two damping elements 5 is arranged in an operative manner between the parking lock pawl 9 and the parking lock gear 7. For this purpose, the damping element 5 is arranged on the parking lock pawl 9 (FIG. 3).

    [0025] The other damping element 5′ is arranged in an operative manner between the parking lock gear 7 and the gear output shaft 8. For this purpose, the damping element 5′ is arranged on the parking lock gear 7 (FIGS. 2A and 2B).
