Abstract
An arrangement for supporting an input gear of a transmission in a motor vehicle, in particular a ring gear, characterized in that a pot-shaped support element (1) is provided, whereby a drive gear to drive the input gear engages into a recess (2) of the support element (1), and, for purposes of bearing the input gear, the support element (1) extends at least partially underneath the input gear radially on the inside.
Claims15
An arrangement for supporting an input gear of a transmission in a motor vehicle, comprising:
- a pot-shaped support element including a radially extending section, an outer collar at an outer circumference thereof protruding axially in a first direction from a radially outer end of the radially extending section, the support element having a recess formed therein for receiving a drive gear driving the input gear, the support element including an inner collar at an inner circumference thereof protruding axially in a second direction opposite the first direction from a radially inner end of the radially extending section, the inner collar configured for extending at least partially axially into the input gear radially inside of an inner circumference of the input gear,
- wherein the radially extending section connects the outer collar and the inner collar, the recess extending radially from the outer collar partially into the radially extending section.
An arrangement for supporting an input gear of a transmission in a motor vehicle, comprising:
- a pot-shaped support element including a radially extending section, an outer collar at an outer circumference thereof protruding axially in a first direction from a radially outer end of the radially extending section, the support element having a recess formed therein for receiving a drive gear driving the input gear, the support element including an inner collar at an inner circumference thereof protruding axially in a second direction opposite the first direction from a radially inner end of the radially extending section, the inner collar configured for extending at least partially axially into the input gear radially inside of an inner circumference of the input gear,
- wherein the input gear is a ring gear,
- wherein, in order to support the ring gear, the ring gear being used to drive a planetary gear, the support element is arranged coaxially to the ring gear, the drive gear being a drive pinion, the drive pinion configured for driving the ring gear, the drive pinion engaging radially into the recess of the support element, the inner collar being a ring on a side of the support element facing the ring gear, the inner collar configured for holding a bearing of the ring gear, the diameter of said inner collar being smaller than that of the ring gear so that the inner collar overlaps at least partially with the inner circumference of the ring gear.

- a pot-shaped support element including a radially extending section, an outer collar at an outer circumference thereof protruding axially in a first direction from a radially outer end of the radially extending section, the support element having a recess formed therein for receiving a drive gear driving the input gear, the support element including an inner collar at an inner circumference thereof protruding axially in a second direction opposite the first direction from a radially inner end of the radially extending section, the inner collar configured for extending at least partially axially into the input gear radially inside of an inner circumference of the input gear,
- wherein, radially on the inside, the support element has a ring support radially outside of the inner collar projecting in the form of a further collar facing away from the inner collar, the ring support forming a ring-shaped axial bearing surface on end face of the support element.
