Definitions
- the present invention relates to a lift according to the preamble of claim 1 and 15.
- An elevator usually comprises a traversable in a bay cabin, which can be coupled to reduce the applied lifting work via a support means with a counterweight to the cabin counterweight.
- the support means may at least partially wrap around one or more drive wheels on which a drive of the elevator applies a torque to hold the car or to proceed.
- the counterweight can ensure the driving ability of such drive wheels.
- the suspension element can wrap around flywheel-like deflecting wheels, which are fastened firmly to the car, the counterweight or inertially in the shaft.
- Driving and deflection wheels are referred to collectively as wheels.
- WO 99/43885 and JP 49-20881 A In addition to steel cables are, for example, from WO 99/43885 and JP 49-20881 A, and flat belt as a support means for elevators known in which four, five or six tension members are arranged side by side in a surrounding these sheath. These flat belts have a longitudinal structure in the form of a plurality of grooves formed between adjacent tension members, which run in the longitudinal direction of the suspension element.
- WO 99/43885 also proposes a drive wheel with a groove in which the flat belt is received and whose groove base has an outer contour complementary to the longitudinal profile of the flat belt with projections which engage in the longitudinal grooves and thus additionally engage the flat belt axially Lead direction.
- the known flat belts Due to the at least four juxtaposed tensile carriers and a jacket enveloping them with essentially the same wall thickness, the known flat belts have a width / height ratio, ie a quotient of the axial flat belt which wraps around the wheel, which is significantly greater than 1.
- WO 99/43885 specifies values of 2, preferably 5, as preferred lower limits of the width / height ratio.
- Such flat belts have the advantage over conventional steel cables to allow smaller deflection radii.
- Object of the present invention is therefore to reduce the wear of the suspension element and to increase the ease of installation.
- a suspension element according to the present invention comprises a tension member arrangement and a jacket which encloses the tension member arrangement and whose outer surface has a longitudinal structure at least in the region which is provided for wrapping around a wheel of the elevator.
- the Buchzanan extract consists only of two tension members. This makes it possible to form the suspension element with a width / height ratio that is greater than 1 and at the same time less than or equal to 3.
- the support means is flat overall and compared to known cables with a circular cross-section, ie a width / height ratio equal to 1, smaller deflection radii and thus allows smaller wheels.
- the upper limit of 3 ensures that the transverse forces occurring in the suspension element do not become too great, thus preventing excessive wear.
- a suspension, whose width / height ratio due to the two Ceinos is in the proposed range, at the same time has sufficient flexibility in the width direction, which increases the ease of installation.
- the tension members may consist of carbon, aramid or other plastics with sufficiently high tensile strength. However, they are preferably made of metallic wires, especially steel wires, which are particularly favorable in terms of manufacturing or deformability, strength and service life.

- the tension members or the steel cables forming them or the wires stranded thereon have a maximum dimension in the range between 1, 25 mm (millimeters) and 4 mm, preferably in a range between 1, 5 mm and 2.5 mm and in particular substantially equal to 1, 5 mm.
- small deflecting radii can advantageously be realized with such tension carriers.
- the tensile carriers may for example have a substantially round cross-section.
- the above-mentioned maximum dimension corresponds to the diameter of the tension member.
- Such a suspension means can be made particularly simple, since in the arrangement of the tension member in the jacket does not have to be paid to the orientation with respect to the longitudinal axis.
- the tension members can also have oval or rectangular cross sections, which are particularly suitable for the realization of the width / height ratio between 1 and 3.
- An alternative embodiment provides that the two tension members touch each other at least punctually. This allows the production of particularly space-saving support means.
- the longitudinal structure of the outer surface of the suspension element preferably has at least one groove extending in the longitudinal direction of the suspension element. This advantageously increases the flexibility of the suspension element without significantly reducing its tensile strength.
- a groove is preferably provided in the region of the outer surface, with which the support means wraps around a wheel of the elevator.
- Such a groove can be produced, for example, in that the outer surface of the suspension element substantially follows an outer contour of the two adjacent tensile members.

- the middle region which corresponds to the pressure-relieved area of the suspension element and the groove, is advantageously approximately 20% to 50% of the suspension element width.
- the jacket can enclose the two tension members respectively trapezoidal. This results in advantageously inclined outer edges of the support means, which advantageously increase the contact force and thus the driving ability of a drive wheel with the same bias due to the wedge effect.
- the support means is formed symmetrically with respect to its in the width direction, ie an axial direction of a looped by the suspension element wheel transverse axis. This facilitates assembly, since the support means also rotated by 180 ° can be applied, and advantageously allows the opposing wrap of successive wheels with identical outer surface contours.
