Abstract
A drive assembly for a motor vehicle drive train includes a shaft including a plurality of axially extending splines defining an outer circumferential surface, and a planet carrier non-rotatably fixed to the shaft by the axially extending splines. The planet carrier and the shaft are axially constrained with respect to each other by a radially inwardly extending material of the planet carrier axially contacting a radially extending surface of the shaft.
Claims19
A drive assembly for a motor vehicle drive train comprising:
- a shaft including a plurality of axially extending splines defining an outer circumferential surface;
- and
- a planet carrier non-rotatably fixed to the shaft by the axially extending splines, the planet carrier and the shaft being axially constrained with respect to each other by a radially inwardly extending material of the planet carrier axially contacting a radially extending surface of the shaft;
- wherein each of the axially extending splines includes an angled displacement section axially contacting the planet carrier.
A method of forming a drive assembly for a motor vehicle drive train comprising:
- spline-cutting a planet carrier with axially extending splines defining an outer circumferential surface of a shaft to non-rotatably fix the planet carrier to the shaft;
- and
- axially constraining the planet carrier and the shaft with respect to each other by forcing a radially inwardly extending material of the planet carrier into axial contact with a radially extending surface of the shaft.
A drive assembly for a motor vehicle drive train comprising:
- a shaft including a plurality of axially extending splines defining an outer circumferential surface;
- and
- a planet carrier non-rotatably fixed to the shaft by the axially extending splines, the planet carrier and the shaft being axially constrained with respect to each other by a radially inwardly extending material of the planet carrier axially contacting a radially extending surface of the shaft;
- wherein the shaft includes a longitudinal base section and a flange section extending radially outward from the longitudinal base section, the flange section including the radially extending surface axially contacting the radially inwardly extending material of the planet carrier.
