Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A resilient torque bar comprising a core axle composed of a substantially incompressible elastic substance, a plurality of layers wound around said core axle alternately in the right and left directions, a plurality of rubber layers, each of said rubber layers being interposed between and directly contacting adjoining pairs of said plurality of said first mentioned layers, and an outer covering provided around the outermost layer for protecting said core axle and said surrounding layers from damage, whereby said plurality of rubber layers prevent said first mentioned layers from directly contacting and being rubbed against each other, impart flexibility and resiliency to the core axle, and relax abrupt shock which is imparted thereto at the time of torque transmission.
Claim 2
Dependent Claim
119 words
A resilient torque bar comprising a core axle composed of a substantially incompressible elastic substance, a plurality of layers wound around said core axle alternately in the right and left directions, a plurality of rubber layers, each of said rubber layers being interposed between and directly contacting adjoining pairs of said plurality of said first mentioned layers, and an outer covering provided around the outermost layer for protecting said core axle and said surrounding layers from damage, whereby said plurality of rubber layers prevent said first mentioned layers from directly contacting and being rubbed against each other, impart flexibility and resiliency to the core axle, and relax abrupt shock which is imparted thereto at the time of torque transmission.
Claim 3
Dependent Claim
21 words
The resilient torque bar according to claim 6, in which said first mentioned plurality of layers are composed of fiber cloth.
Claim 4
Dependent Claim
22 words
The resilient torque bar according to claim 6, in which said first mentioned plurality of layers are composed of metal wire net.
Claim 5
Dependent Claim
25 words
The resilient torque bar according to claim 6, in which said first mentioned plurality of layers are wound around the core axle on the bias.
Claim 6
Dependent Claim
40 words
The resilient torque bar according to claim 6, in which the elastic substance constituting the core axle is selected from the group consisting of hard rubber and synthetic resins having hardness of 70 to 80 measured in accordance with JIS-K-6301.
