Abstract
Abstract Disclosed herein is a vibration damping device for a mechanical clutch release system for a motor vehicle having a clutch cable comprising an outer cable mounted to the body of the motor vehicle and to the engine at one end and at the other end which is positioned forwardly of an exhaust pipe respectively and an inner cable mounted to a clutch pedal and to a clutch release fork at one end outwardly extending from the one end of the outer cable and at the other end outwardly extending from the other end of the outer cable respectively. The vibration damping device comprises a cylindrical body which is enclosingly secured to the inner cable between the other end of the outer cable and the clutch release fork to increase flexural rigidity of the inner cable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
Apparatus for damping vibrations in a motor vehicle having a body, an engine, an exhaust pipe, a clutch pedal, and a clutch release fork comprising: an outer clutch cable mounted at one end to the body of said motor vehicle, and mounted at the other end to the engine, forward of the exhaust pipe; an inner clutch cable, partially enclosed within said outer cable, mounted at one end to said clutch pedal and mounted at the other end to said clutch release fork, and having an exposed portion extending from said clutch release fork to said other end of said outer cable; a vibration damping device comprising a cylindrical damper of high flexural rigidity, enclosing at least a portion of, and being secured to, said exposed portion of said inner cable.
Claim 2
Dependent Claim
131 words
Apparatus for damping vibrations in a motor vehicle having a body, an engine, an exhaust pipe, a clutch pedal, and a clutch release fork comprising: an outer clutch cable mounted at one end to the body of said motor vehicle, and mounted at the other end to the engine, forward of the exhaust pipe; an inner clutch cable, partially enclosed within said outer cable, mounted at one end to said clutch pedal and mounted at the other end to said clutch release fork, and having an exposed portion extending from said clutch release fork to said other end of said outer cable; a vibration damping device comprising a cylindrical damper of high flexural rigidity, enclosing at least a portion of, and being secured to, said exposed portion of said inner cable.
Claim 3
Dependent Claim
24 words
The invention as defined in claims 1 or 6, wherein the ends of said damper are larger in outer diameter than the center thereof.
Claim 4
Dependent Claim
17 words
The invention as defined in claims 1 or 6, wherein said damper has a uniform outer diameter.
Claim 5
Dependent Claim
26 words
The invention as defined in claim 3 wherein end portions of said damper are made of material of greater mass than that of the center thereof.
Claim 6
Dependent Claim
27 words
The invention as defined in claim 3, wherein end portions of said damper are made of material of greater flexural rigidity than that of the center thereof.
Claim 7
Dependent Claim
39 words
