Abstract
Abstract A flange member detachably secured on a monotube suspension unit for supporting an external coil spring has a tubular part which coaxially surrounds the tube and has an inturned flange at one end for abutting an end of the tube, under the force of the coil spring, to retain the flange member on the tube. A lug or recess on the inturned flange co-operates with a respective recess or projection of a rod guide within the tube to locate the flange member angularly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A monotube suspension unit comprising a tube and an external flange member surrounding said tube for supporting one end of an external coil compression spring, and means for detachably mounting said flange member to said tube intermediate the ends of the working space thereof comprising stop means carried by said flange member in axially spaced relationship thereto, abutment means carried by said tube beyond one end of said working space and engageable by said stop means, said stop means and said abutment means being adapted to be held in engagement with each other to retain said flange member on said tube in its position of use by the force of the spring which said flange member supports.
Claim 2
Dependent Claim
117 words
A monotube suspension unit comprising a tube and an external flange member surrounding said tube for supporting one end of an external coil compression spring, and means for detachably mounting said flange member to said tube intermediate the ends of the working space thereof comprising stop means carried by said flange member in axially spaced relationship thereto, abutment means carried by said tube beyond one end of said working space and engageable by said stop means, said stop means and said abutment means being adapted to be held in engagement with each other to retain said flange member on said tube in its position of use by the force of the spring which said flange member supports.
Claim 3
Dependent Claim
54 words
A unit according to claim 1 wherein said flange member has a tubular portion co-axially slideable over said tube, said tubular portion having an inturned flange at one end constituting said stop means, said inturned flange being engagable with one end of said tube constituting said abutment means to locate said flange member axially.
Claim 4
Dependent Claim
39 words
A unit according to claim 2 wherein a rod guide is located in said outer tube, and said tubular portion and said rod guide are provided with co-operating engagement means to locate the flange member angularly on said tube.
Claim 5
Dependent Claim
36 words
A unit according to claim 3 wherein said inturned flange of said tubular portion has a lug and said rod guide has a recess, said lug engaging in said recess to locate said flange member angularly.
Claim 6
Dependent Claim
35 words
A unit according to claim 3 wherein said inturned flange of the tubular portion has a recess and said rod guide has a projection which engages in said recess to locate said flange member angularly.
