Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
In a final drive line of a motor vehicle, the improvement comprising, in combination, a propeller shaft and a final pinion drive shaft, a universal joint attached to the rear end of said propeller shaft and having a yoke portion, a flange attached to the front end of said final pinion drive shaft, and an additional joint including an annular member secured to said yoke portion of said universal joint, an intermediate member received in said annular member and secured to said flange of said final pinion drive shaft, said intermediate member being spaced axially and radially apart from said annular member, a resilient member filling a space formed between said annular member and said intermediate member and drivably connecting said annular member and said intermediate member, said intermediate member having an axial bore formed therethrough, a cylindrical member extending through said axial bore and secured at its front end to said annular member, a needle bearing carried on said cylindrical member for maintaining the rotary axis of said cylindrical member in alignment with the rotary axis of said intermediate member, a radial flange formed on said cylindrical member and a pair of thrust bearings mounted on both sides respectively of said radial flange on said cylindrical member for thereby carrying an axial thrust force applied to said annular member and said intermediate member in either direction.
Claim 2
Dependent Claim
227 words
In a final drive line of a motor vehicle, the improvement comprising, in combination, a propeller shaft and a final pinion drive shaft, a universal joint attached to the rear end of said propeller shaft and having a yoke portion, a flange attached to the front end of said final pinion drive shaft, and an additional joint including an annular member secured to said yoke portion of said universal joint, an intermediate member received in said annular member and secured to said flange of said final pinion drive shaft, said intermediate member being spaced axially and radially apart from said annular member, a resilient member filling a space formed between said annular member and said intermediate member and drivably connecting said annular member and said intermediate member, said intermediate member having an axial bore formed therethrough, a cylindrical member extending through said axial bore and secured at its front end to said annular member, a needle bearing carried on said cylindrical member for maintaining the rotary axis of said cylindrical member in alignment with the rotary axis of said intermediate member, a radial flange formed on said cylindrical member and a pair of thrust bearings mounted on both sides respectively of said radial flange on said cylindrical member for thereby carrying an axial thrust force applied to said annular member and said intermediate member in either direction.
Claim 3
Dependent Claim
112 words
A joint assembly for a torque transmitting drive line having a rotary drive member and a rotary driven member, comprising a connecting member drivable by the drive member to rotate therewith, an intermediate member received in said connecting member forming a clearance therebetween, said intermediate member having an axial bore, a resilient member filling the clearance between said connecting member and said intermediate member and drivingly connecting said connecting member with said intermediate member for driving the driven member, a cylindrical member extending through the axial bore and secured at one end to said connecting member to rotate therewith, and a needle bearing rotatably supporting said cylindrical member in said intermediate member.
Claim 4
Dependent Claim
112 words
A joint assembly for a torque transmitting drive line having a rotary drive member and a rotary driven member, comprising a connecting member drivable by the drive member to rotate therewith, an intermediate member received in said connecting member forming a clearance therebetween, said intermediate member having an axial bore, a resilient member filling the clearance between said connecting member and said intermediate member and drivingly connecting said connecting member with said intermediate member for driving the driven member, a cylindrical member extending through the axial bore and secured at one end to said connecting member to rotate therewith, and a needle bearing rotatably supporting said cylindrical member in said intermediate member.
Claim 5
Dependent Claim
38 words
A joint assembly as claimed in claim 2, including a radial flange on an outer periphery of said cylindrical member, and a pair of thrust bearings, one on each side of said radial flange, in said intermediate member.
Claim 6
Dependent Claim
222 words
A joint assembly for a torque transmitting drive line having a propeller shaft and a final pinion drive shaft of a motor vehicle, comprising a universal joint secured to an end of the propeller shaft, an annular member secured to said universal joint to rotate therewith, an intermediate member received in said annular member and spaced axially and radially apart from said annular member to form a space therebetween, said intermediate member being secured to the final pinion drive shaft to rotate therewith and having an axial bore, a resilient member filling the space between said annular member and said intermediate member, a cylindrical member received in said axial bore and secured at one end to said annular member, said annular member having an end wall facing said propeller shaft, said end wall having a central stepped up portion projecting toward said pinion drive shaft, said intermediate member being a substantially square block and having an end face facing said end wall and matching the shape of said end wall, first means for maintaining the rotary axis of said annular member in alignment with the rotary axis of said intermediate member, and second means for carrying an axial thrust force between said annular and intermediate members, said first means including a needle bearing provided on the outer periphery of said cylindrical member.
Claim 7
Dependent Claim
222 words
A joint assembly for a torque transmitting drive line having a propeller shaft and a final pinion drive shaft of a motor vehicle, comprising a universal joint secured to an end of the propeller shaft, an annular member secured to said universal joint to rotate therewith, an intermediate member received in said annular member and spaced axially and radially apart from said annular member to form a space therebetween, said intermediate member being secured to the final pinion drive shaft to rotate therewith and having an axial bore, a resilient member filling the space between said annular member and said intermediate member, a cylindrical member received in said axial bore and secured at one end to said annular member, said annular member having an end wall facing said propeller shaft, said end wall having a central stepped up portion projecting toward said pinion drive shaft, said intermediate member being a substantially square block and having an end face facing said end wall and matching the shape of said end wall, first means for maintaining the rotary axis of said annular member in alignment with the rotary axis of said intermediate member, and second means for carrying an axial thrust force between said annular and intermediate members, said first means including a needle bearing provided on the outer periphery of said cylindrical member.
Claim 8
Dependent Claim
39 words
A joint assembly as claimed in claim 4, wherein said second means includes a radial flange formed on the outer periphery of said cylindrical member and a pair of thrust bearing, one on each side of said radial flange.
