Abstract

A clutch device configured for a transmission may include a first body and a second coaxially mounted to the first body; a friction element mounted between the first body and the second body; a friction piston configured to axially press the friction element by use of hydraulic pressure; a retractable mechanism including a dog clutch, which is configured to restrict rotation between the first body and the second body, and repeatedly engaging and disengaging the dog clutch by repeatedly applying pressure in axial direction thereof; and an operation piston configured to provide pressure to the retractable mechanism in an axial direction of the retractable mechanism.

Description

technical field [0001] The present invention relates to the construction of a power control device used in a transmission. Background technique [0002] Automotive automatic transmissions and the like may use multiple power control devices that are hydraulically operated to engage a desired gear. [0003] That is, various gear positions may be shifted by engaging or disengaging rotation elements of the planetary gear set using a plurality of power control devices such as clutches or brakes. [0004] A "clutch" is a device that engages or disengages two rotating parts that rotate separately, and a "brake" is a state that stops one rotating element and one rotating when one of the two rotating elements is a fixed part such as a transmission housing A device that converts the state of a component's rotation. [0005] That said, clutches and brakes are pretty much the same in actual construction, other than whether or not the target part is all rotating. [0006] A mechanism ...
