Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
In a drive mechanism for a railway vehicle comprising a vehicle frame, at least two axles supporting said frame, wheels joined to said axles, a single motor between said axles, a drive shaft rigidly connected to said motor for each axle, a bevel gear joined to each drive shaft adjacent each axle, and elastic means for transferring the bevel gear movement to each axle, the improvement in which said elastic means is composed of a driven bevel gear connected to a single elastic coupling between the driven bevel gear and the axle for driving said axle, a separate transverse torque reaction strut adjacent each axle pivotally joining said motor to said frame for holding said motor against twisting in said frame, said bevel gear and its adjacent strut for one axle being positioned diagonally opposite the bevel gear and axle for the other axle relative to the center of the frame, and the weight of said motor, drive shaft, gears and coupling being supported solely upon said axles.
Claim 2
Dependent Claim
168 words
In a drive mechanism for a railway vehicle comprising a vehicle frame, at least two axles supporting said frame, wheels joined to said axles, a single motor between said axles, a drive shaft rigidly connected to said motor for each axle, a bevel gear joined to each drive shaft adjacent each axle, and elastic means for transferring the bevel gear movement to each axle, the improvement in which said elastic means is composed of a driven bevel gear connected to a single elastic coupling between the driven bevel gear and the axle for driving said axle, a separate transverse torque reaction strut adjacent each axle pivotally joining said motor to said frame for holding said motor against twisting in said frame, said bevel gear and its adjacent strut for one axle being positioned diagonally opposite the bevel gear and axle for the other axle relative to the center of the frame, and the weight of said motor, drive shaft, gears and coupling being supported solely upon said axles.
Claim 3
Dependent Claim
64 words
In a mechanism as in claim 1, said driven gear (7) being mounted on a hollow shaft (9) concentric with the axle, and said elastic coupling comprising a flange (10) joined to said hollow shaft and extending perpendicularly outwardly beyond the axle, an annular disc (11) connected to the axle, and an elastic member (12) connected between said flange (10) and said disc (11).
Claim 4
Dependent Claim
32 words
In a mechanism as in claim 2, further comprising a rim (14) on the periphery of said flange (10), and said elastic member being connected to the inner surface of said rim.
