Problems solved by technology

However, this method has several disadvantages, including the inability to move the "movable element" to the desired position under certain conditions, such as a torque-lock situation that prohibits sliding movement of the "movable element" or a tooth-to-tooth contact

Embodiment Construction

[0016] with reference to the attached figure 1 and figure 2 , an exemplary clutch assembly constructed in accordance with the teachings of the present disclosure is indicated generally at 10 . The clutch assembly 10 may include a first clutch member 12, a clutch spring 14, a second clutch member 16, a first apply plate 18, a first clutch pack 20, a first backing plate 22, a first retaining ring 24, a third clutch member 26 , the second application plate 28 , the second clutch pack 30 , the second back plate 32 and the second retaining ring 34 . In the particular example provided, clutch assembly 10 is used to selectively transmit rotational power to a first or high-range input (not shown) and a second or high-range input of an electric drive unit (not shown). A low-range input (not shown). The electric drive unit may include a two-speed transmission (not shown) receiving rotational power transmitted through the clutch assembly 10 and a differential assembly (not shown) rec...

Abstract

A clutch assembly with a clutch input (12), first and second clutch outputs (16, 26), a first clutch pack (20) between the clutch input and the first clutch output, and a second clutch pack (30) between the clutch input and the second clutch output. A clutch spring (14) is positioned in the clutch assembly to engage the first clutch pack so that rotary power is normally transmitted from the clutchinput, through the first clutch pack to the first clutch output. Disengagement of the first clutch pack occurs automatically when the second clutch pack is engaged to transmit rotary power between the clutch input and the second clutch output.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 422,651, filed November 16, 2016, the disclosure of which is incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to a clutch assembly. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] It is relatively common in two-speed transmissions to have a clutch pack with a "movable element" capable of a first position, a second position, and intermediate positions between the first and second positions position, the first position operates the two-speed transmission in a first ratio, the second position operates the two-speed transmission in a second ratio, and the intermediate position operates the two-speed transmission in an idle mode (i.e. , allowing independent relative rotation ...
