Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
An automotive two-wheeled vehicle having a rear wheel mounting structure comprising: a swing arm having at its rear end a bore extending transversely of the length of the vehicle and having its front end supported on the vehicle body in a vertically swingable manner; an axle case mounted in said swing arm bore and having an axle-supporting bore extending therethrough transversely of the vehicle, the ends of the axle case projecting from the respective ends of the swing arm bore by a predetermined amount; axle bearing means disposed in the projecting end portions of said axle case; an axle rotatably supported in the said axle-supporting bore by way of said bearing means and having each of its ends projecting from the respective ends of said axle case bore by a sapredeteremined amount; a rear wheel removably mounted to one end portion of said axle where it projects on one side of said swing arm; and a power transmission member removably mounted to the other end portion of said axle where it projects on the other side of said swing arm, for transmitting the driving force of a power unit of the vehicle to said axle by way of an endless type transmission member.
Claim 2
Dependent Claim
203 words
An automotive two-wheeled vehicle having a rear wheel mounting structure comprising: a swing arm having at its rear end a bore extending transversely of the length of the vehicle and having its front end supported on the vehicle body in a vertically swingable manner; an axle case mounted in said swing arm bore and having an axle-supporting bore extending therethrough transversely of the vehicle, the ends of the axle case projecting from the respective ends of the swing arm bore by a predetermined amount; axle bearing means disposed in the projecting end portions of said axle case; an axle rotatably supported in the said axle-supporting bore by way of said bearing means and having each of its ends projecting from the respective ends of said axle case bore by a sapredeteremined amount; a rear wheel removably mounted to one end portion of said axle where it projects on one side of said swing arm; and a power transmission member removably mounted to the other end portion of said axle where it projects on the other side of said swing arm, for transmitting the driving force of a power unit of the vehicle to said axle by way of an endless type transmission member.
Claim 3
Dependent Claim
57 words
A vehicle as claimed in claim l, wherein the said axle has a larger outside diameter portion and a smaller outside diameter portion, and wherein one of said bearing means is a needle bearing which supports said larger diameter portion and the other of said bearing means is a ball bearing which supports said smaller diameter portion.
Claim 4
Dependent Claim
24 words
A vehicle as claimed in claim 2, wherein said larger diameter portion of said axle is located towards the rear wheel mounting end thereof.
Claim 5
Dependent Claim
71 words
A vehicle as claimed in claim 2 or 3, wherein said axle has an axial bore including a larger diameter portion corresponding to said larger outside diameter portion of said axle and a smaller diameter portion corresponding to said smaller outside diameter portion thereof, said larger diameter portion of the bore containing a collar member having a through-hole of the same diameter as the said smaller diameter portion of the bore.
Claim 6
Dependent Claim
74 words
A vehicle as claimed in any preceding claim, wherein a flange is provided on said one projecting end portion of said axle, a hub of said rear wheel is fitted over said one projecting end portion, and a nut member is screwed onto the extremity of said one projecting end portion to hold said wheel hub between said nut member and said flange, whereby said wheel is attached to said axle for rotation therweith.
Claim 7
Dependent Claim
31 words
A vehicle as claimed in claim 5, including supporting pins mounted on said flange and received in holes in said wheel hub to prevent rotation of the wheel on the axle.
Claim 8
Dependent Claim
