Abstract
Abstract An accumulator arrangement for the storage and release of braking energy, and for the braking and driving of a rotating shaft by means of a flywheel. The rotating shaft which is to be braked or driven, is connected to a drive or gear unit having 2° of freedom; one output of which is coupled to the flywheel via an installation operable either as a generator or a motor, and whose other output is connected with a second installation operable as a generator or a motor, and the two installations are connected with each other for energy transmission, preferably through a buffer or shock absorbing device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
In a vehicular transmission including a power plant for driving an output shaft through the intermediary of a flywheel, an improvement comprising a gear drive having two degrees of freedom connected to said shaft, said gear drive having a first output; a first device operable selectively as a generator or motor connected to said first output and to said flywheel; a second device selectively operable as a generator or motor; said gear drive having a second output connected to said second drive; and buffer means interconnecting said first and second devices for the transfer of energy therebetween.
Claim 2
Dependent Claim
97 words
In a vehicular transmission including a power plant for driving an output shaft through the intermediary of a flywheel, an improvement comprising a gear drive having two degrees of freedom connected to said shaft, said gear drive having a first output; a first device operable selectively as a generator or motor connected to said first output and to said flywheel; a second device selectively operable as a generator or motor; said gear drive having a second output connected to said second drive; and buffer means interconnecting said first and second devices for the transfer of energy therebetween.
Claim 3
Dependent Claim
17 words
The improvement as claimed in claim 1, said first and second devices each being a fluid-driven motor.
Claim 4
Dependent Claim
17 words
The improvement as claimed in claim 1, said first and second devices each being a fluid-driven pump.
Claim 5
Dependent Claim
17 words
The improvement as claimed in claim 1, said first and second device each being a pneumatic motor.
Claim 6
Dependent Claim
16 words

Claim 9
Dependent Claim
38 words
The improvement as claimed in claim 1 comprising control means coupled to said first and second devices and to said buffer means for controlling the operation of said devices in accordance with the pressure in said buffer means.
Claim 10
Dependent Claim
18 words
The improvement as claimed in claim 8 wherein the pressure in said buffer means is maintained substantially constant.
