Abstract

Official abstract text for this publication.

A number of variations may include a transmission assembly comprising a housing and a plurality of components within the housing comprising a drive motor that emits electromagnetic interference, a differential assembly, a first shaft connecting the drive motor to the differential assembly, and an output stub shaft connected to the differential assembly and thread through a hole in the housing to connect to a driveshaft wherein the output stub shaft comprises a noise reduction component constructed and arranged to reduce electromagnetic interference from the transmission assembly to the driveshaft.

First claim

Opening claim text (preview).

1 . A product comprising: a transmission assembly comprising a housing and a plurality of components within the housing comprising a drive motor that emits electromagnetic interference, a differential assembly, a first shaft connecting the drive motor to the differential assembly, and an output stub shaft connected to the differential assembly and thread through a hole in the housing to connect to a driveshaft wherein the output stub shaft comprises a noise reduction component constructed and arranged to reduce electromagnetic interference from the transmission assembly to the driveshaft. 2 . A product as set forth in claim 1 wherein the product comprises an electric vehicle. 3 . A product as set forth in claim 1 wherein the drivetrain is connected to a wheel assembly. 4 . A product as set forth in claim 1 wherein the noise reduction component is introduced to the output stub shaft through electrophoretic disposition. 5 . A product as set forth in claim 1 wherein the noise reduction component comprises an organic resin. 6 . A product as set forth in claim 1 wherein the noise reduction component comprises a non-conducting material. 7 . A product as set forth in claim 1 wherein the noise reduction component is app lied as a coating on the spline of the output stub shaft. 8 . A product as set forth in claim 1 wherein a noise reduction component is app lied to the first shaft. 9 . A product as set forth in claim 1 wherein a noise reduction component is app lied to the housing. 10 . A product as set forth in claim 1 wherein a noise reduction component is app lied to the driveshaft. 11 . A method comprising: providing a transmission assembly comprising a housing and a plurality of components within the housing comprising a drive motor that emits electromagnetic interference, a differential assembly, a first shaft connecting the drive motor to the differential assembly, and an output stub shaft connected to the differential assembly and thread through a hole in the housing to connect to a driveshaft wherein the output stub shaft comprises a noise reduction component constructed and arranged to reduce electromagnetic interference from the transmission assembly to the driveshaft; and operating the transmission assembly such that the noise reduction component reduces electromagnetic interference from the transmission assembly to the driveshaft. 12 . A method as set forth in claim 11 wherein the product comprises an electric vehicle. 13 . A method as set forth in claim 11 wherein the drivetrain is connected to a wheel assembly. 14 . A method as set forth in claim 11 wherein the noise reduction component is introduced to the output stub shaft through electrophoretic disposition. 15 . A method as set forth in claim 11 wherein the noise reduction component comprises an organic resin. 16 . A method as set forth in claim 11 wherein the noise reduction component comprises a non-conducting material. 17 . A method as set forth in claim 11 wherein the noise reduction component is applied as a coating on the spline of the output stub shaft. 18 . A method as set forth in claim 11 wherein a noise reduction component is applied to the first shaft. 19 . A method as set forth in claim 11 wherein a noise reduction component is applied to the housing. 20 . A method as set forth in claim 11 wherein a noise reduction component is applied to the driveshaft.
