TRANSMISSION ELECTRONIC SHIFTER WITH ADJUSTABLE DAMPED FRICTION CLUTCH

摘要

An electronic shifter can include a base, a shift lever assembly, a detent system and a clutch system. The shift lever assembly can include a pivot base having a coupling member. The detent system can include a biasing member and a detent member associated with the shift lever assembly. The biasing member can bias the detent member into engagement with a cam member. The clutch system can include a flexible clutch member and a bearing area having a bearing surface. The bearing area can be associated with the base and can receive the coupling member and clutch member to pivotably couple the shift lever assembly to the base. The detent system can apply a downward force onto the coupling member thereby forcing the clutch member against the bearing surface and providing frictional damping of the shift lever assembly during movement thereof proportional with a biasing force of the biasing member.

1. An electronic shifter assembly for a shift-by-wire transmission, comprising:
a base; a shift lever assembly including a pivot base having a coupling member; a detent system including a biasing member and a detent member associated with the shift lever assembly, the biasing member biasing the detent member into engagement with a cam member coupled to the base; and a clutch system including a flexible clutch member and a bearing area having a bearing surface, the bearing area associated with the base and configured to receive the coupling member with the flexible clutch member associated therewith to pivotably couple the shift lever assembly to the base; wherein the detent system is configured to apply a downward force onto the coupling member thereby forcing the flexible clutch member against the bearing surface and providing tuned frictional damping of the shift lever assembly during movement thereof proportional with a biasing force of the biasing member.
