Dual flex plate drive

Claim 2

In a vehicle drive assembly, in combination, (a) a power source having an output, (b) a transmission axially spaced from said power source and having an input, (c) a coupling axially aligned with and positioned between said power source and said transmission, (d) said coupling having means connecting said coupling to said power source and to said transmission, (e) said means comprising two flexible plates, (f) each said flexible plate being secured along its outer peripheral portion to flanges on said coupling, (g) one of said flexible plates being secured along its inner peripheral portion to the output of the power source, (h) the other of said flexible plates being secured along its inner peripheral portion to the input of the transmission, (i) a spacer ring secured between each flexible plate and said coupling, and (j) oppositely extending pilots formed on each said ring with one pilot engaging the coupling and the other pilot engaging one of said flexible plates, said pilots positioning said flexible plates and said coupling relative to each other.

Claim 3

A vehicle drive assembly having, (a) a torque converter with an output yoke, (b) a transmission axially spaced from said torque converter and having an input yoke, (c) a coupling axially aligned with and positioned between said torque converter and said transmission, (d) said coupling having a drive tube and flexible means connecting said drive tube to said torque converter and to said transmission, (e) said flexible means comprising plural discs of resilient material laminated together to form flexible plates, (f) each said flexible plate being secured along its outer peripheral portion to said drive tube, (g) one of said flexible plates being secured along its inner peripheral portion to the output yoke of the torque converter, (h) the other of said flexible plates being secured along its inner peripheral portion to the input yoke of the transmission, and (i) a spacer ring positioned between each said flexible plate and said drive tube, each said spacer ring having axially and oppositely extending pilots, one pilot engaging said spacer ring and the other pilot engaging said drive tube for positioning said flexible plates and said drive tube relative to each other.

Claim 4

A vehicle drive assembly having, (a) a torque converter with an output yoke, (b) a transmission axially spaced from said torque converter and having an input yoke, (c) a coupling axially aligned with and positioned between said torque converter and said transmission, (d) said coupling having a drive tube and flexible means connecting said drive tube to said torque converter and to said transmission, (e) said flexible means comprising plural discs of resilient material laminated together to form flexible plates, (f) each said flexible plate being secured along its outer peripheral portion to said drive tube, (g) one of said flexible plates being secured along its inner peripheral portion to the output yoke of the torque converter, (h) the other of said flexible plates being secured along its inner peripheral portion to the input yoke of the transmission, and (i) a spacer ring positioned between each said flexible plate and said drive tube, each said spacer ring having axially and oppositely extending pilots, one pilot engaging said spacer ring and the other pilot engaging said drive tube for positioning said flexible plates and said drive tube relative to each other.

Claim 5

A vehicle drive assembly as claimed in claim 2 wherein a third pilot is provided on both the input yoke and the output yoke, said flexible plates seating on said third pilots for positioning said plates relative to said input and output yokes.

Claim 6

A vehicle drive assembly as claimed in claim 1 wherein a third pilot is provided on both the input yoke and the output yoke, said flexible plates seating on said third pilots for positioning said plates relative to said input and output yokes.
