Abstract
The invention concerns a universal flexible sheath with bellow for articulated joint and equipment for fixing said sheath. The protective sheath consists of a tubular element (4, 5, 6, 7, 8) with fixing zones at its ends and a central conical bellow (1), whereof the folds comprise sloping flanks forming an angle of 0 to 45° with the sheath axis on the large diameter side and of 60 to 80° on the small diameter side, said sheath being associated with flexible or ductile mounting cones whereof the base diameter is variable. The invention concerns equipment for repair shops and the sheath is designed for protecting lubricated joints for transmitting movement to mobile members, and in particular to transmission elements in motor vehicles.
Claims33
A flexible sheath comprising:
- a conical central bellows for an articulated joint for protecting lubricated joints and for transmitting movement to mobile members;
- said flexible sheath further comprising a tubular element;
- wherein the tubular element further comprises at least one fixing zone on each end;
- said tubular element further comprising said conical central bellows;
- each said at least one fixing zone further comprising an outer clamping surface for receiving a clamp and an inner surface comprising at least one attachment rib,
- wherein the at least one attachment rib is located on the inner surface of the at least one fixing zone at a position other than a middle of the outer clamping surface and offset towards the conical central bellows.
A combination comprising:
- a steering rack;
- and
- at least two protective sheaths for a steering rack, each of said at least two protective sheaths comprising:
- a flexible connector having an open end provided with several sections of different diameters for compensating for the differences in pressure that exist between the two protective sheaths, each protective sheath having a bellows mounted at each end of the steering rack;
- wherein one end of the flexible connector includes a cap which is integral with the wall of the sheath such that it can be easily removed or pierced when used on a power steering, so as to enable the sheath to be mounted on non-assisted mechanical racks.
A device for installing a flexible sheath on an articulated joint comprising:
- one of, a flexible or ductile mounting cone;
- said mounting cone having a base diameter for installing a sheath;
- said sheath having different diameters of articulations for use in transmission joints or steering rack cases.
A flexible sheath for an articulated joint comprising:
- a centrally located conical bellows;
- said sheath further comprising a tubular element for retaining contents therein and formed with at least two fixing zones on at least one end;
- said tubular element having an inside surface and an outside surface;
- and
- one of the two fixing zones having a different diameter than a diameter of another of the two fixing zones,
- at least one of the two fixing zones further comprising an outer clamping surface for receiving a clamp and an inner surface comprising at least one attachment rib,
- wherein the at least one attachment rib is located on the inner surface of the at least one fixing zone at a position other than a middle of the outer clamping surface and offset towards the conical bellows.
A mounting cone for installing a flexible sheath on an articulated joint comprising:
- a tapered tubular member which is, one of, flexible or ductile;
- said tapered tubular member having at least one integrally formed stop for engaging the articulated joint;
- wherein the mounting cone facilitates the installation of a flexible sheath on an articulated joint.
A mounting cone for installing a flexible sheath on an articulated joint comprising:
- a tapered tubular member which is, one of, flexible or ductile;
- said tapered tubular member having a plurality of integrally formed hollow sawteeth;
- wherein the hollow sawteeth can relax or retract as a function of the diameter of the articulated joint.
