Claim 5

A waste kinetic energy reclaiming system for a vehicle having an engine driving the vehicle having brakes, the system comprising: (a) a generator; (b) coupling means for coupling the generator and the engine at variable torque ratios, said coupling means comprising first and second pulleys having variable effective diameters and a fixed length belt looping said first and second pulleys to drivingly connect them, the distance between respective centers of the first and second pulleys being fixed whereby the effective diameter of the first pulley increases as that of the second pulley decreases and vice versa, a driven shaft for connecting the second pulley to the generator; and (c) a clutch connected to said first pulley and responsive to the application of said brakes for connecting said engine to said generator via said coupling means; wherein the second pulley further comprises opposing first and second disks, the first disk being rotatably mounted on the driven shaft, and restrained from moving axially with respect to the driven shaft, and means for connecting the second disk to the driven shaft said connecting means being operable for rotating the second disk while allowing for axial movement with respect to the driven shaft so that a distance between the first and second disks is variable, the first and second disks having opposing tapered surfaces defining a groove having a V-shaped cross-section for receiving the belt, whereby the effective diameter of the second pulley increases as the second disk axially approaches the first disk.

Claim 6

A waste kinetic energy reclaiming system as recited in claim 5, wherein the clutch includes an annular plate rigidly mounted on the driven shaft, and an interposed member slideably engaging both the second disk and the annular plate to connect the second disk to the driven shaft.

Claim 7

A waste kinetic energy reclaiming system as recited in claim 6, wherein the interposed member includes a ball, and wherein the annular plate and the second disk have opposing grooves respectively for receiving the ball.

Claim 8

A waste kinetic energy reclaiming system as recited in claim 7, wherein the opposing grooves extend radially and have a V-shaped cross-section.

Claim 9

A waste kinetic energy reclaiming system as recited in claim 6, wherein the annular plate and the second disk have opposing grooves respectively disposed on their opposing surfaces, and wherein the interposed member includes a ring having a zigzag profile and dimensioned to be receivable in the opposing grooves of the annular plate and the second disk.

Claim 10

A waste kinetic energy reclaiming system as recited in claim 9, wherein the opposing grooves of the annular plate and the second disk extend radially and have a V-shaped cross-section.

Claim 11

A waste kinetic energy reclaiming system as recited in claim 6, wherein interposed member includes a ball contacting both the annular plate and the second disk, wherein the second disk has a groove for receiving the ball, and wherein the annular plate has a flat surface for contacting the ball.

Claim 12

A waste kinetic energy reclaiming system as recited in claim 11, wherein the groove extends radially and has a symmetric V-shaped cross-section.
