Definitions
- the invention relates to the technical field of cable air transport installations.
- the invention relates to a drive device that can be used in such facilities.
- Driving vehicles such as cabs or seats, of a cable transport installation continuous scrolling aerial with uncoupling of vehicles in stations, is conventionally obtained, at stations, by means of wheels friction drive.
- Such wheels engage an elongated cross member grip which extends in the direction of travel vehicles whose length is conventionally greater than the spacing between two successive wheels of friction.
- the cross is secured to the vehicle in displacement.
- the speed increases or decreases from one wheel to another and the grip cross member, still in friction contact with one wheel, engages the next wheel rotating at a speed different.
- the area of high adhesion can for example be rough and the area of reduced adhesion, smooth.
- the surface condition of the sleeper, and particularly its aging, tire wear, presence of water, frost, grease on the sleeper can lead to reduced friction drives.
- the invention relates to a device which can be used in installations air transport by cables, and not having the disadvantages of the devices known from the prior art.
- the notched strip presents, in cross section in a plane, a section substantially rectangular.
- the notched strip presents, in cross section in a plane, a section substantially trapezoidal.
- the width of the strip is substantially equal to the width of the pneumatic tires of the wheels carrying the landforms.
- the height of the notches of the strip is less than the minimum height of the reliefs of the wheels, measured according to a radial direction of these wheels.
- the height of the notches of the strip is less than the dimension of the reliefs measured according to a plane tangent to the perpendicular to the wheels.
- the drive device according to the invention can be used for training in stations vehicles of a cable air transport installation, such as a cable car or chairlift.
- Load support carts for example seats of a chairlift or cabins of a gondola, not represented, drive in the station, after uncoupling cable, on a transfer rail.
- these wheels 1 are regularly spaced from each other.
- These wheels 1 cooperate with a cross member grip, carried by the trolley.
- These wheels 1 are rotated by a motor, not shown, or by a PTO on the cable.
- These wheels can be interconnected by transmission belts passing over fixed pulleys on the axes 2 of the wheels 1.
- the wheels 1 are driven at the same speed which corresponds to the speed of movement of the load support carriage.
- the first wheel at the entrance to the station, rotates at cable speed while as the speed of the following wheels gradually decreases to reach normal traffic speed.
- Each cross is covered with a notched strip 3, according to the invention.
- This notched strip 3 is slightly greater than the distance D between two wheels 1 successive, so as to always be in contact with at least a wheel 1.
- the notched strip 3 can be, in section transverse according to plane P, of general shape rectangular or trapezoidal.
- the underside 4 of the notched strip 3 can be smooth or striated, for example to facilitate its hanging on the cross member of the load support trolley.
- the width l 3 of the notched strip 3 is substantially equal to the width of the wheels 1.
- the width l 3 of the notched strip 3 is greater than the width of the wheels 1, the notched strip 3 projecting laterally on either side of the wheels 1, by a distance equal or not.
- two bands notched or more than two notched bands are arranged substantially parallel to each other, a interval separating these parallel notched bands.
- Two notched bands can thus be arranged so as to be facing reliefs 5 bandages tires of the wheels 1, these reliefs 5 not extending across the width of the wheels 1.
- the notched strip 3 can be produced by polychloroprene or based on polychloroprene reinforced with oriented fibers giving great transverse rigidity.
- the notched strip 3 may include, in its part base 5, a reinforcement such as polyester fibers, high tensile strength and fatigue. These polyester fibers can be embedded in a bonding gum.
- the height h t of the notches is less than the minimum height h 5 of the reliefs 5 of the wheels 1.
- This height h t of the notches 6 is less than a third of the total height h s of the strip 3, in the embodiment shown.
- the longitudinal dimension S 6 of the substantially planar upper face 7, of the notches 6, is less than the dimension S 5 of the reliefs 5 of the wheels 1, measured tangentially to the wheels 1.
- This longitudinal dimension S 6 of the upper face 7 of the notches 6 is, in one embodiment, variable along the transverse direction T.
- this dimension S 6 increases from one side edge 8 of the strip 3 to the opposite side edge.
- this dimension S 6 is increasing from a lateral edge 8 of the strip 3, passes through a maximum, then decreases in the direction of the opposite lateral edge of the edge 8.
- angles of inclination ⁇ , ⁇ 'of the walls 9, 10 relative to the vertical are equal.
- angles of inclination ⁇ , ⁇ 'of the walls 9, 10, relative to the are different.
- the height h t of the notches 6 is constant, with respect to the transverse direction T, in one embodiment.
- the height h t of the notches 6 varies, starting from a lateral edge 8 of the strip 2 and going towards the opposite lateral edge, this height h t possibly increasing from an edge 8 to the edge opposite, or even increase, go through a maximum, to decrease towards the edge opposite edge 8.
- the longitudinal dimension S 11 of the faces 11 separating the notches 6 is greater than the dimension S 5 of the notches 5 defined above.
- the geometry of the notched strip 3 and that of the reliefs 5 of the wheels 1 are such that the mechanism drive can work in two modes different.
- a first mode is shown in Figures 2 and 3.
- the training is carried out by friction of the reliefs 5 of the pneumatic tires of wheels 1 against the upper faces 7 of the notches 6.
- the reliefs 5 do not penetrate into the spaces separating the notches 6.
- the second operating mode is shown in Figures 4 and 5.
- the training is carried out by contact between the reliefs 5 and the faces 8, 9 limiting the notches 6 as well as by friction between the peripheral surface of the relief 5 and the faces 11 of the notched strip 3.
- zones 6, 11 may include microreliefs further improving the transmission of efforts.
- Anti-slip coatings can also be provided on pneumatic tires and / or belts notched 3.
- Switching from one operating mode to another provides drive speeds and transmit efforts significantly higher than those obtained by pure friction.
- each wheel tends to impose its speed on the crosses.
- the device according to the invention makes it possible to eliminate such phenomena, thus ensuring excellent transmission of effort and accelerations and decelerations higher, resulting in improved throughput for cable air transport facilities.
