First Claim
Patent Images
1. A braked clutch arrangement comprising:
- a. a support including a housing;
b. a clutch shaft rotatable relative to said support about an axis;
c. a brake member enveloped by said housing and axially movable on said shaft in angularly secured relationship;
d. a friction member secured on said support in said housing against rotation about said axis;
e. pressure-fluid operated moving means for moving said brake member into engagement with said friction member,1. said moving means including a pressure member axially movable in said housing in angularly secured relationship and engageable with said brake member for pressing the brake member axially against said friction member;
f. clutch release means for releasing said shaft from a driven clutch portion, said clutch release means including a clutch control member mounted for movement between an inoperative position and a clutch releasing position, and further beyond said clutch releasing position; and
g. fluid control means responsive to said further movement for controlling flow of pressure fluid to said moving means.

Abstract
The output shaft of an automotive friction clutch may be braked during shifting of the transmission into higher gear by a brake disc secured against rotation on the shaft and axially moved into engagement with a friction member on a non-rotating element of the vehicle by a pressure plate backed by a resilient wall of a chamber to which a pressure fluid is admitted when the driver depresses the clutch pedal further than needed for only disengaging the clutch. A switch closed by the pedal opens a solenoid valve in the pressure line to the chamber.
