Abstract
Abstract A clutch which includes hub means adapted to be positively connected for rotation with a shaft, and disc means having the plane thereof extending radially with regard to said hub means for receiving and supporting friction lining means, said hub means including means operable to establish a rotational elastically limited play between said disc means and said hub means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A clutch which includes: disc means for receiving and supporting friction means, a two-part hub having an inner part adapted to be positively connected for rotation with a shaft, and an outer part connected to said disc means by circumferentially yielding resilient means, said hub including driving means operable to establish an angularly limited rotational play between said parts, said hub parts having radially spaced, circumferential, axially extending surfaces, and annular friction bearing means interposed between and in contact with sAid circumferential, axially extending surfaces and having frictional slidable contact with at least one of said surfaces to provide frictional resistance to circumferential relative movement of said friction bearing means and at least one of said surfaces so that said rotational play is free of any returning force.
Claim 2
Dependent Claim
128 words
A clutch which includes: disc means for receiving and supporting friction means, a two-part hub having an inner part adapted to be positively connected for rotation with a shaft, and an outer part connected to said disc means by circumferentially yielding resilient means, said hub including driving means operable to establish an angularly limited rotational play between said parts, said hub parts having radially spaced, circumferential, axially extending surfaces, and annular friction bearing means interposed between and in contact with sAid circumferential, axially extending surfaces and having frictional slidable contact with at least one of said surfaces to provide frictional resistance to circumferential relative movement of said friction bearing means and at least one of said surfaces so that said rotational play is free of any returning force.
Claim 3
Dependent Claim
30 words
In a clutch as claimed in claim 1, said friction bearing means comprising friction bearing members on opposite sides of the plane of said disc means between said hub parts.
Claim 4
Dependent Claim
50 words
A clutch according to claim 2, in which the outer periphery of the inner hub part and the inner periphery of the outer hub part are provided with intermeshing teeth forming said driving means with said teeth on the inner and outer hub parts spaced to provide said rotational play.
Claim 5
Dependent Claim
19 words
A clutch according to claim 1 in which said rotational play is within the range of 2* to 8*.
Claim 6
Dependent Claim
16 words
A clutch according to claim 1 in which said friction bearing means are of elastic material.
Claim 7
Dependent Claim
19 words
A clutch according to claim 1, in which said friction bearing means includes sealing means and grease chamber means.
Claim 8
Dependent Claim
38 words
A clutch according to claim 1, which includes at least two bearings respectively arranged at the ends of the two hub parts, the intermeshing teeth and tooth spaces of said hub parts being located between said bearing means.
Claim 9
Dependent Claim
22 words
A clutch according to claim 1, in which said rotational free play is within an angular range of from 2* to 8*.
