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.
Claims20
A gear assembly for a motor vehicle comprising:
- at least one shaft having an axis of rotation and defining an axial direction:
- 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 at least one damping element is arranged in an operative manner between the gear component and the shaft,
- wherein the damping element is produced at least in part from amorphous metal, and
- wherein the at least one damping element extends continuously circumferentially around an inner diameter of the gear component;
- wherein the damping element defines an end face at an axial end of the damping element, wherein the end face is continuous along the end face and defines a closed loop along a common plane around the end face.
A parking lock mechanism for a motor vehicle, the parking lock mechanism comprising:
- at least one gear output shaft defining a central rotational axis:
- at least one parking lock gear fixedly arranged on the gear output shaft;
- at least one parking lock pawl moveable from a disengaged position to an engaged position with the parking lock gear;
- and
- at least one damping element arranged in an operative manner between the parking lock gear and the gear output shaft,
- wherein the damping element is produced at least in part from amorphous metal, and
- wherein the damping element defines a closed circumferential loop around an outer diameter of the gear output shaft and an inner diameter of the parking lock gear;
- wherein the damping element is disposed continuously to extend both radially and circumferentially between the gear output shaft and the parking lock gear in a common plane perpendicular to a central rotational axis of the gear output shaft;
- wherein the common plane is disposed at an axial end face of the damping element;
- wherein the gear output shaft includes a plurality of outwardly extending teeth, wherein the damping element is disposed radially between the outwardly extending teeth and an inner surface of the parking lock gear at the end face of the damping element.
A gear assembly for a motor vehicle comprising:
- at least one shaft defining a central rotational axis:
- at least one gear component, wherein the gear component is fixedly arranged on the shaft;
- at least one engagement component moveable into a locking position with the gear component;
- and
- a first damping element arranged in an operative manner between the gear component and the shaft,
- a second damping element arranged in an operative manner between the engagement component and the gear component;
- wherein the first and second damping elements are produced at least in part from amorphous metal;
- wherein the first damping element is ring-shaped and extends circumferentially along an interface between the gear component and the shaft;
- wherein the first damping element defines a closed loop along a common plane defined by an axial end face of the first damping element.
