Abstract
Abstract The invention relates to a vehicle clutch release mechanism adapted for actuation in the release stage of the clutch disc assembly so as to separate the assembly from engagement with a flywheel rotatable in unison with an input shaft, said assembly being axially shiftable and unitarily rotatable on an output shaft. The improvement resides in the provision of resilient means preferably formed into a rubber ring or tube which is adapted for accumulating a resilient thrust energy during the engagement of said clutch disc assembly with the flywheel and for release of said accumulated thrust energy during a clutch release operation for positively and resiliently separating said assembly from contact with said flywheel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
A vehicle clutch release mechanism comprising, an engine crankshaft having a fly wheel mounted thereon, a cover plate attached to said fly wheel, a pressure plate mounted for axial sliding movement relative to said fly wheel and said cover plate, an output shaft concentrically mounted on and provided between said fly wheel and said pressure plate, said clutch disc assembly having a hub mounted for axial sliding movement on and for rotation in unison with said output shaft, a pilot bearing mounted between said crankshaft and said output shaft having an inner race and an outer race, said outer race being fixed to said crankshaft and said inner race being fixed to said output shaft, and elastic ring means provided between said hub of said clutch disc assembly and said inner race of said pilot bearing for positively releasing said clutch disc assembly from engagement with said fly wheel, said elastic ring means including an elastic sleeve, a resilient ring attached to an inner peripheral surface of said elastic sleeve and a stepped sleeve attached to an inner peripheral surface of said resilient ring.
Claim 2
Dependent Claim
184 words
A vehicle clutch release mechanism comprising, an engine crankshaft having a fly wheel mounted thereon, a cover plate attached to said fly wheel, a pressure plate mounted for axial sliding movement relative to said fly wheel and said cover plate, an output shaft concentrically mounted on and provided between said fly wheel and said pressure plate, said clutch disc assembly having a hub mounted for axial sliding movement on and for rotation in unison with said output shaft, a pilot bearing mounted between said crankshaft and said output shaft having an inner race and an outer race, said outer race being fixed to said crankshaft and said inner race being fixed to said output shaft, and elastic ring means provided between said hub of said clutch disc assembly and said inner race of said pilot bearing for positively releasing said clutch disc assembly from engagement with said fly wheel, said elastic ring means including an elastic sleeve, a resilient ring attached to an inner peripheral surface of said elastic sleeve and a stepped sleeve attached to an inner peripheral surface of said resilient ring.
Claim 3
Dependent Claim
34 words
A vehicle clutch release mechanism as set forth in claim 1 wherein said elastic sleeve is connected to said hub and said stepped sleeve is connected to said inner race of said pilot bearing.
Claim 4
Dependent Claim
207 words
A vehicle clutch release mechanism comprising, an engine crankshaft having a fly wheel mounted thereon, a cover plate attached to said fly wheel, a pressure plate mounted for axial sliding movement relative to said fly wheel and said cover plate, an output shaft concentrically mounted on and rotatable relative to said crankshaft, a clutch disc assembly provided between said fly wheel and said pressure plate, said clutch disc assembly having a hub mounted for axial sliding movement on and for rotation in unison with said output shaft, a pilot bearing mounted between said crankshaft and said output shaft having an inner race and an outer race, said outer race being fixed to said crankshaft and said inner race being fixed to said output shaft, and elastic ring means provided between said hub of said clutch disc assembly and said inner race of said pilot bearing for positively releasing said clutch disc assembly from engagement with said fly wheel, said elastic ring means including a resilient part having a number of fine circular grooves on the inside wall surface thereof and a sleeve having a larger sleeve part with circular grooves corresponding to said fine circular grooves on the outer peripheral surface thereof and a smaller sleeve part.
Claim 5
Dependent Claim
207 words
A vehicle clutch release mechanism comprising, an engine crankshaft having a fly wheel mounted thereon, a cover plate attached to said fly wheel, a pressure plate mounted for axial sliding movement relative to said fly wheel and said cover plate, an output shaft concentrically mounted on and rotatable relative to said crankshaft, a clutch disc assembly provided between said fly wheel and said pressure plate, said clutch disc assembly having a hub mounted for axial sliding movement on and for rotation in unison with said output shaft, a pilot bearing mounted between said crankshaft and said output shaft having an inner race and an outer race, said outer race being fixed to said crankshaft and said inner race being fixed to said output shaft, and elastic ring means provided between said hub of said clutch disc assembly and said inner race of said pilot bearing for positively releasing said clutch disc assembly from engagement with said fly wheel, said elastic ring means including a resilient part having a number of fine circular grooves on the inside wall surface thereof and a sleeve having a larger sleeve part with circular grooves corresponding to said fine circular grooves on the outer peripheral surface thereof and a smaller sleeve part.
Claim 6
Dependent Claim
35 words
A vehicle clutch release mechanism as set forth in claim 3 wherein said resilient part is connected to said hub and said smaller sleeve part is connected to said inner race of said pilot bearing.
Claim 7
Dependent Claim
55 words
A vehicle clutch release mechanism as set forth in claim 3 wherein said fine circular grooves of said resilient part and said circular grooves of said larger sleeve part are frictionally interconnected to permit longitudinal adjustment to regulate the longitudinal lengths by a relative movement of said part upon wearing of said clutch disc assembly.
