Abstract
Abstract A device of brake power supply, wherein a rotation disk is set on a shaft transmitting rotation from an engine so as to make possible rotation toward a fixed direction regardless of the rotation direction of the shaft, a clutch disk being placed in contact with the rotation disk by the operation of a brake pedal, lever or similar means, causing the clutch disk to rotate together with the rotation disk, and adding a strong driving power to a master brake cylinder by a connection between the piston of the brake cylinder and a band wound around the clutch disk. The torque of the clutch disk may also be applied directly to the brake shoes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
In a vehicular braking system utilizing longitudinal movement means for applying the brakes, and wherein the vehicle power train includes a drive shaft, an apparatus for applying the torque of the drive shaft to the longitudinal movement means comprising: a disc concentrically mounted on the drive shaft for rotation thereon; transmission means interconnecting said disc and said drive shaft for unidirectionally rotating said disc by either clockwise or counterclockwise rotation of said drive shaft; a brake drive wheel rotatably mounted on said drive shaft; elongated flexible band means having one end attached to the periphery of said brake drive wheel and a portion thereof wrapped around the periphery of said wheel, the other end of said band means being connected to the longitudinal movement means; and clutch means for applying the torque of the rotation of said disc to said brake drive wheel.
Claim 2
Dependent Claim
143 words
In a vehicular braking system utilizing longitudinal movement means for applying the brakes, and wherein the vehicle power train includes a drive shaft, an apparatus for applying the torque of the drive shaft to the longitudinal movement means comprising: a disc concentrically mounted on the drive shaft for rotation thereon; transmission means interconnecting said disc and said drive shaft for unidirectionally rotating said disc by either clockwise or counterclockwise rotation of said drive shaft; a brake drive wheel rotatably mounted on said drive shaft; elongated flexible band means having one end attached to the periphery of said brake drive wheel and a portion thereof wrapped around the periphery of said wheel, the other end of said band means being connected to the longitudinal movement means; and clutch means for applying the torque of the rotation of said disc to said brake drive wheel.
Claim 3
Dependent Claim
135 words
The apparatus of claim 1 further including a first tube splined on said drive shaft for rotation therewith and wherein said disc is rotatably mounted on said first tube and includes a clutch face on one side thereof, a second tube rotatably mounted on said first tube, said second tube having longitudinal splines on its outer periphery, and wherein said clutch means includes a clutch plate mounted on said second tube for longitudinal movement along said splines and rotation therewith, a clutch plate driving ring mounted adjacent said clutch plate on said second tube for longitudinal movement along said splines and rotation therewith and means for advancing said clutch plate to the clutch face of said disc through said clutch plate driving ring, and wherein said brake drive wheel is splined to said second tube.
Claim 4
Dependent Claim
135 words
The apparatus of claim 2 wherein said transmission means includes first and second oppositely disposed cam races in the outer surface of said first tube, said disc being mounted on said first cam race for rotation in one direction therewith, said transmission means also including a sun gear mounted on said second cam race for rotation therewith in the opposite direction, a ring gear concentric with said sun gear, a plurality of planetary gears interconnecting said sun gear and said ring gear, a collar integral with said disc and extending over the outer surface of said ring gear, and a third cam race in the outer surface of said ring gear for unidirectionally driving said disc through said collar, whereby said disc is unidirectionally driven regardless of the direction of rotation of said drive shaft.
