- the aforementioned longitudinal movement transmission cables are intended to transfer to the automatic change of speeds the displacements that the user prints to the control lever of this automatic change, the flexible nature of these transmission cables determining their use as an element of link between the aforementioned lever and automatic change given the relative situation between the two that generally implies that said link is made following a wavy path.
- these longitudinal movement transmission cables are basically composed of a longitudinal central band or core housed in a cover adapted to the operating conditions of the cable, which central core can slide longitudinally from the cover by means of bearings .
- the cable is disclosed of precision longitudinal movement transmission according to the invention.
- the precision longitudinal movement transmission cable object of the invention has a tubular cover of structure and composition suitable to each specific application case, and is characterized by comprising:
- the retention means available to the central core consist of a helically wound metallic wire and uniformly around said core and in its entire length, which winding is housed in grooves that, forming angularity in correspondence with said helical winding, configure the free ends of the radial projections of the central core, so that, in the grooved grooves, compartments of equal length contiguously are defined.
- the cable according to the invention also offers, due to its own characteristic structure, a very high reliability and precision of operation as well as a minimum wear of its constituent elements, which, under usual conditions of use, ensures a very high number of maneuvers or displacements of the central core with respect to the roof in its reciprocating path.
- the tubular cover under normal conditions of use, is fixed at its respective ends by means of corresponding terminals connected to the control lever of the automatic transmission and to the corresponding mechanism of this change.
- the maximum length that the central core can be displaced longitudinally with respect to the tubular cover of the precision longitudinal movement transmission cable according to the invention is precisely given by the retention means available to the central core, and, in particular, by the length of the compartments that said retention means define in each of the grooved grooves of the central core.
- each ball housed in its corresponding compartment of the central core can, by being applied longitudinally to one of the ends of this central core a sufficient force that moves it from the cover, simultaneously rolling on the inner surface of the tubular cover and on the surface of the corresponding grooved groove of the central core to the extent given by the length of said compartment.
- the ball reaches the retention means that define said compartment, in any of the two possible directions of displacement of the central core and the said force applied at one of its ends is maintained, said ball cannot continue rolling and could only continue sliding and rubbing on the two surfaces mentioned.
- this friction occurs along the entire length of the cable in the plurality of balls housed in their respective compartments that define said retention means in the central core of the cable according to the invention, which is the reason why , from the moment in which the displacement of the central core with respect to the cover is such that the balls housed in the compartments of this central core terminate the rolling path, together they resist such a high resistance that it is necessary apply a very large force so that said central core continues to move.
- the precision longitudinal movement transmission cable according to the invention can, on the one hand, carry out the transmission of longitudinal movement under the conditions detailed above, and, on the other hand, limit said longitudinal movement by adapting it to the needs posed by each specific case of application, consequently avoiding that the mechanisms and / or devices receiving said longitudinal movement, or what is the same traction and compression force receptors, are exposed to mechanical overloads that are on many occasions cause of breakdown and / or malfunction to of said mechanisms and / or devices.
- Figure 1 is a partially sectional view of the motion transmission cable according to the invention.
- Figure 2 is the view corresponding to section II-II obtained from Figure 1.
- the precision longitudinal movement transmission cable object of the invention which is described as an example, is composed, as shown in section in Figure 2 of the drawing sheet, by the central core N and the tubular cover T It contains it.
- the precision longitudinal movement transmission cable according to the invention is intended to link, as mentioned above, the joystick arranged inside the vehicle interior with the automatic gearshift.
- the transmission cable has corresponding connection terminals at both ends which, for purposes of greater clarity of exposure, have not been represented on the drawing sheet.
- Figures 1 and 2 show how the tubular cover T is composed, in this embodiment of the precision longitudinal movement transmission cable according to the invention, by the outer protective sheath 1, by the plurality of reinforcing cables 2, and, by the inner raceway cover 3.
- the outer protective sheath 1 and the inner race cover 3 are preferably obtained from plastic materials of mechanical performance suitable for their respective purposes.
- the cables 2 are arranged between said outer protective sheath 1 and inner race cover 3 concentrically wrapping this inner cover 3 and extending along the entire length of the tubular cover T , which cables 2 are metallic in nature and act as a structural reinforcement for the T-sheath.
- tubular cover T can adopt any other composition and structure suitable to the needs that each specific case of application of the precision longitudinal motion transmission cable object of the invention, the detailed description given above being only for the purposes of exemplary embodiment.
- Figure 1 shows as the central core . it extends in the length given by the tubular cover T, which central core . it is provided with a central axial reinforcement constituted by the metallic cable
- Figure 2 shows how the central core N. It is essentially cylindrical shape and configures the radial projections 5 equal and equal to each other and which, in this embodiment, are in number of five.
- the number of radial projections 5 may vary depending on the needs of each specific application case, remarking that the minimum number of radial projections 5 with which adequate operation of the longitudinal movement transmission cable of Accuracy according to the invention is three.
- the radial projections 5 extend without loss of continuity throughout the central core N and are essentially trapezoidal section with their shorter bases arranged at the free ends of said radial projections 5, as shown in Figure 2.
- Figure 2 shows how the radial projections 5 are sized so that they define the grooved grooves 6 of curved contour which, like the radial projections 5, extend, in this exemplary embodiment, along the entire central core N .
- Figure 1 shows.
- the number of grooved grooves 6 is equal to the number of radial projections 5.
- the free ends of the radial projections 5 define, as shown in Figure 2, the theoretical outer diameter of the central core J, which diameter, which is smaller than the inner diameter of the tread cover 3 of the tubular cover X, allows that, from tightly, the central core N. with respect to said tubular cover I slide longitudinally and rotate on itself.
- Figures 1 and 2 show how helical winding is uniformly wound around the central core N, which is fixed positionally with respect to the central core N by the action of the transverse grooves 8 which, forming the same rity angulation with respect to the longitudinal axis of the central core N. that the one that defines the helical winding of the metallic wire 7, configures the free ends of the radial projections 5 of said central core hJ-
- transverse grooves 8 are sized so that they contain with adjustment the portions of metallic wire 7 that cross them, in this way, the metallic wire 7 does not protrude with respect to the central core M, as shown in Figures 1 and 2 .
- Figure 1 shows how the metallic wire 7 helically wound around the central core .- defines in the grooved grooves 6 the longitudinal compartments 9 which along the entire central core are of equal length and transversely adjacent, which compartments 9 they are thus delimited, longitudinally, by the portions of metallic wire 7 that cross them forming angularity, and, transversal-
- Figure 1 shows the position occupied by the central core N relative to the tubular casing T when said central core N. no action is exerted, under these conditions, the balls 10 housed in their respective compartments 9 occupy the position indicated in Figure 1, that is, in contact with the metallic wire 7 which, as described above, longitudinally delimits the ends of each of the compartments 9, being, under normal conditions of use of the cable according to the invention, the balls 10 retained in this position by the adjustment with which they are housed in their respective compartments 9; to being applied at the end A of the central core N sufficient force in the direction directed as S.
- the central core N travels longitudinally with respect to the tubular cover T in this direction S resting on the balls 10 that simultaneously roll on the inner surface of the raceway cover 3 of the tubular cover T and on the inner surface ⁇ rior of the grooved grooves 6 of the central core N, whereby, with respect to the tubular cover T and with sufficient approximation, the longitudinal displacement of the central core N doubles the longitudinal displacement of the balls 10; once the balls 10 reach the opposite end of their respective compartments 9 and in case the said force is applied on the end A of the central core N in the direction indicated as S_, said balls 10 by the action of the metallic wire 7 are they are prevented from continuing rolling so that they can only continue sliding and rubbing on the surfaces mentioned, that is, the inside of the tread cover 3 and that of the grooved grooves 6; consequently, the joint action of friction originating in the immediately preceding conditions the plurality of balls 10 housed in their respective behaviors of the core 9 prevents, in normal use, the central core N.
