Abstract
A power delivery system including an input shaft for transmitting driving power of an engine, an output shaft mounted concentrically with the input shaft, a pump mounted concentrically between the input and output shafts and connected to the input shaft, a fluid coupling having a turbine connected to the output shaft, a case containing the fluid coupling, and a power cut-off device, characterized in that the power cut-off device is provided with a frictional coupling element and a servo mechanism thereof and mounted in the aforementioned case.
Claims12
A power delivery system comprising:
- an input shaft for transmitting the driving force of an engine;
- a driven output shaft;
- a fluid coupling for transmitting the driving force from said input shaft to said output shaft, said fluid coupling having a fluid coupling casing connected to and rotatably driven by said input shaft, and a turbine member provided in said fluid coupling casing for being driven by fluid responsive to the rotation of said fluid coupling casing;
- a power cut-off clutch for selectively coupling said turbine member with said output shaft, said power cut-off clutch being provided in said casing and having a clutch plate connected to said turbine member, said clutch plate being mounted concentrically with and radially inward of said turbine member, and a clutch disk connected to said output shaft;
- a servomechanism for selectively coupling said power cut-off clutch, said servomechanism having biasing means fixed to said fluid coupling casing to rotate therewith for biasing said clutch plate into engagement with said clutch disk to transmit driving force from said turbine member to said output shaft;
- a first thrust bearing provided between said biasing means and said clutch plate and clutch disk set;
- and
- a second thrust bearing provided between said clutch plate and clutch disk set and said fluid coupling casing.

A power delivery system comprising:
- an input shaft for transmitting the driving force of an engine;
- a driven output shaft;
- a fluid coupling for transmitting the driving force from said input shaft to said output shaft, said fluid coupling having:
- a fluid coupling casing mounted on and rotatably driven by said input shaft;
- a plurality of pump blades mounted on the interior of said fluid coupling casing;
- and
- a turbine member including a turbine shell rotatably mounted within said casing and a plurality of turbine blades mounted within said shell opposite said pump blades;
- a power cut-off clutch for selectively coupling said turbine member to said output shaft, said power cut-off clutch being mounted within said fluid coupling casing concentrically with and radially inward of said turbine member and comprising:
- a clutch disk wheel mounted within said fluid coupling casing on said output shaft for rotation therewith;
- a radially extending clutch disk plate rotatably mounted within said fluid coupling casing;
- a clutch plate casing including a hollow cylindrical portion and an integral, radially extending annular wall portion fixed to said clutch disk plate;
- means for engaging said clutch disk plate with said turbine shell whereby said clutch disk plate and said clutch plate casing are rotatably driven with said turbine member;
- a set of clutch plates supported by said clutch plate casing;
- and
- a set of clutch disks intermeshed with said clutch plates and supported by said clutch disk wheel;
- a servomechanism for operating said power cut-off clutch, said servomechanism comprising first biasing means, mounted within and fixed to said fluid coupling casing for rotation therewith, for forcing said intermeshed clutch and clutch disk sets into frictional engagement whereby driving force is transmitted from said turbine member to said cutch disk wheel and said output shaft;
- a first thrust bearing mounted between said biasing means and said intermeshed clutch plate and clutch disk sets;
- and
- a second thrust bearing interposed between said clutch disk plate and said fluid coupling casing.
