Clutch disc with coaxial brake

Claim 2

A brake for stopping a rotatable member driven by a clutch said clutch having a flywheel, a pressure plate and a clutch disc, said clutch disc being on said rotatable member and forced into driving relation with said flywheel by said pressure plate characterized by brake means on said clutch disc to rotate therewith, a stationary member engagable by said brake means, said brake means actuated by said pressure plate to disengage said brake means from said stationary member and to rotate with said clutch disc on engagement of said clutch and on disengagement of said clutch said brake means engaging said stationary member to stop said rotatable member.

Claim 3

A brake as set forth in claim 1 wherein said driven member is an input shaft of a transmission.

Claim 4

A brake as set forth in claim 1 wherein said brake means is at least one brake plate on said clutch disc.

Claim 5

A brake as set forth in claim 3 wherein said one brake plate has pads for engaging said pressure plate.

Claim 6

A brake as set forth in claim 3 wherein said one brake plate is axially slidable and circumferentially fixed on said clutch disc to slide from said stationary member on engagement of said clutch.

Claim 7

A brake as set forth in claim 5 wherein springs are provided and said springs engage said one brake member plate and press said plate against said stationary member.

Claim 8

A brake as set forth in claim 1 wherein said stationary member comprises a fixed flange.

Claim 9

A brake as set forth in claim 3 wherein said input shaft includes a flange fixed thereto, springs means mounted between said flange and said one brake plate to urge said brake plate against said stationary member.

Claim 10

A brake as set forth in claim 1 wherein said brake means is two brake plates.

Claim 11

A brake as set forth in claim 8 wherein one of said brake plates is axially slideable and circumferentially fixed on said clutch disc and the other brake plate is circumferentially fixed on said clutch disc.

Claim 12

A brake as set forth in claim 7 wherein said stationary member includes a fixed casing with an extension and said flange is mounted on said extension, said braking plate is forced against said flange.

Claim 13

A brake as set forth in claim 1 wherein said stationary member has an engaged portion and a supporting portion, a resilient ring-shaped member between said engaged portions and supporting said engaged portion, and parallel to said clutch disc to provide limited movement of said engaged portion and said supporting portion.

Claim 14

A brake for stopping a rotatable shaft driven by a clutch having a flywheel, a pressure plate and a clutch disc affixed to said rotatable shaft and forced into driving relation with said flywheel by said pressure plate characterized by a stationary member around said rotatable shaft and having a flange parallel to said clutch disc, a brake member axially slideable and circumferentially fixed on said clutch disc, a flange like member on said shaft on the opposite side of said clutch disc from said brake member, springs between said flange-like member and said brake member to urge said brake member against said flange, on engagement of said clutch said pressure plate actuating said brake member to compress said springs and disengage said brake member from said flange and on disengagement of said clutch said springs forcing said brake member against said flange to be in braking relation with said rotatable shaft.

Claim 15

A brake for stopping a rotatable shaft driven by a clutch having a flywheel, a pressure plate and a clutch disc affixed to said rotatable shaft and forced into driving relation with said flywheel by said pressure plate characterized by a stationary member around said rotatable shaft and having a flange parallel to said clutch disc, a brake member axially slideable and circumferentially fixed on said clutch disc, a flange like member on said shaft on the opposite side of said clutch disc from said brake member, springs between said flange-like member and said brake member to urge said brake member against said flange, on engagement of said clutch said pressure plate actuating said brake member to compress said springs and disengage said brake member from said flange and on disengagement of said clutch said springs forcing said brake member against said flange to be in braking relation with said rotatable shaft.

Claim 16

A brake for stopping a rotatable shaft driven by a clutch having a flywheel, a pressure plate and a radially extending clutch disc affixed to said rotatable shaft and forced into driving relation with said flywheel by said pressure plate characterized by a stationary member around said rotatable shaft having a flange parallel to said radially extending clutch disc; a shoe on said flange; a first radially extending brake plate and a second brake plate; said first brake plate axially and circumferentially fixed on said clutch disc said second brake plate axially slideable and circumferentially fixed on said clutch disc; a flange-like, radially extending member on said shaft on the opposite side of said clutch disc from said second brake plate; springs between said flange-like member and said second brake plate to press said first and second brake plates into braking contact with said first and second brake shoes respectively on disengagement of said clutch, said springs forcing said first and second brake plates against said first and second shoes, respectively, to be in braking relation with said rotatable shaft, said pressure plate actuating said second brake plate and compressing said springs and disengaging said first and second brake plates from said shoes upon engagement of said clutch.

Claim 17

A brake for stopping a rotatable shaft driven by a clutch having a flywheel, a pressure plate and a radially extending clutch disc affixed to said rotatable shaft and forced into driving relation with said flywheel by said pressure plate characterized by a stationary member around said rotatable shaft having a flange parallel to said radially extending clutch disc; a shoe on said flange; a first radially extending brake plate and a second brake plate; said first brake plate axially and circumferentially fixed on said clutch disc said second brake plate axially slideable and circumferentially fixed on said clutch disc; a flange-like, radially extending member on said shaft on the opposite side of said clutch disc from said second brake plate; springs between said flange-like member and said second brake plate to press said first and second brake plates into braking contact with said first and second brake shoes respectively on disengagement of said clutch, said springs forcing said first and second brake plates against said first and second shoes, respectively, to be in braking relation with said rotatable shaft, said pressure plate actuating said second brake plate and compressing said springs and disengaging said first and second brake plates from said shoes upon engagement of said clutch.
