Definitions

  • the invention relates to a device for the automatic length correction of cables, in particular for adjusting brake cables or the like, with a housing having a receptacle and a rack or the like which is displaceably guided in the receptacle, the housing and the rack or the like. are each coupled to the transmitter and the slave via a cable or the like.
  • Devices of this type for correcting the length of mechanically flexible remote controls are known in many different ways. They are used for automatic adjustment or readjustment of the length of the cable as soon as elongation due to wear of the braking device or elongation of the cable due to aging occurs. In terms of function, these known devices have proven their worth, but in one way or another these devices are in need of further improvement. For example, a blockage of the slave, for example the brake under the action of frost, leads to an irreversible shortening of the cable system in some known adjusting devices, with the result that the adjusting device only has to be brought back to the initial state by hand in order to properly operate the System. Furthermore, in other known devices for actuating the slave, a large stroke movement of the encoder is required, which may have an adverse effect on the size of the encoder and the required installation space.
  • the object of the invention is to provide a device with the above-mentioned features to further develop that an improved function and handling is guaranteed.
  • a particularly advantageous, in itself independent development of the invention is that the transmission is designed as a transmission gear, wherein a stroke of the encoder cable is translated into an enlarged, in particular approximately double stroke of the slave cable.
  • a stroke of the encoder cable is translated into an enlarged, in particular approximately double stroke of the slave cable.
  • the gearbox is realized in a structurally particularly simple and inexpensive embodiment in that, in particular in an opening or the like.
  • a wall of the housing at least one, in particular two, gears are rotatably supported, which engage with the toothing of the rack. While with a deactivated encoder the rack engages with the toothing in the gear or gears and can be freely moved back and forth in the manner of a freewheel in the receptacle of the housing under the effect of the preload or another force emanating from the slave, when activated the encoder a non-positive and / or positive coupling between the rack and the housing or the encoder cables.
  • the housing in order to bring about the automatic coupling between the toothed rack and the housing when the sensor is activated, the housing is slidably received in a guide, the guide having counter-toothing which engages with the at least when the sensor is activated a gear.
  • the housing is pulled around the actuation path towards the encoder side, the gearwheels rolling on the rack coming into engagement with the counter-toothing of the stationary guide.
  • the movement of the cable in the direction of the encoder and the additional rolling movement of the gears on the counter-toothing of the guide also results in a 1: 2 ratio, which means that the user-side cable pulls twice as far as the sensor-side cable pull.
  • a stroke movement on the encoder cable is a double stroke on the cable Nehmers translated.
  • this translation only half the stroke movement on the transmitter side is required in comparison to the known device in order to generate a corresponding stroke movement on the slave side that is comparable with conventional devices.
  • the cables are decoupled, so that, in addition to an automatic length adjustment in the sense of removing loose parts on the overall system, an elongation of the device, for example after a blockage has been lifted, is also ensured.
  • the rack in a delivery or pre-assembly state of the device by means of a locking element or the like, the rack is in an i. w. maximum extended position held.
  • This proves to be advantageous in that the ends of the cable pulls can be easily mounted on the slave or encoder. After completion of the assembly, this locking element can be easily removed for unlocking or releasing the rack, and an initial setting can be carried out to compensate for the slack in the system.
  • FIG. 1 shows a schematic illustration of an exemplary embodiment of the device according to the invention in a starting position before the initial setting
  • FIG. 1 shows the device of Figure 1 in the
  • Figure 3 shows the device of Figure 2 in an operating position
  • Figure 1 shows the delivery state of the adjusting and adjusting device to the belt of the automobile manufacturer.
  • the adjustment device is extended to the maximum length to make it easier to install the cable ends on the encoder and receiver side.
  • Reference number 1 denotes a housing of the automatic adjusting device, which is displaceably guided in a fixed guide 2, for example fastened to the floor panel of the vehicle.
  • the housing 1 has a receptacle 3, into which a rack 4 can be inserted.
  • the rack 4 is connected on its opposite end to the cable end of the cable 6 leading to the slave side.
  • a compression spring 9 is used between a fixed abutment 7 on the vehicle side, which has an opening 8 for the passage of the cable 6 and the facing end of the rack 4.
  • a holder 10 is arranged for fixing the cable 11 leading to the sensor side. Furthermore, there are at least one, preferably at least one on the housing 1 two gears 12 are mounted, which are in engagement with the teeth 5 of the rack 4. As described in more detail below, the gear wheels 12 are designed such that when the housing 1 is displaced in the guide 2 they also come into engagement with counter teeth 13 on the likewise fixed guide 2.
  • the rack 4 is removed from the housing 1 to the maximum length, as shown in FIG. 1, in order to be able to mount the cables 6, 11 on the slave 16 and encoder 14. For this u. U. a locking element may be provided which holds the adjustment in this maximum extended position.
  • Another advantage of the adjusting device is that the system is open in the non-actuated state according to FIG. 2, so to speak has a free-wheel. If, when the transmitter side is actuated, as shown in FIG. 3, the slave side is blocked, for example as a result of frost action, after the transmitter 14 has been moved into its initial position or the handbrake actuation lever has been put down, when the blockage of the slave side is later released, an adjustment is also made in the opposite direction, i.e. in the direction of one Extension of the cable system.
  • blocking the slave side leads to the fact that the adjustment device tries irreversibly to shorten the cable system additionally, with the result that the adjustment device only has to be brought back to the initial state by hand in order to ensure proper fastening of the system. This is particularly disadvantageous because the driver of the vehicle cannot usually determine whether the braking system is frozen or not in colder seasons.

Abstract

L'invention concerne un dispositif de correction automatique de la longueur de câbles sous gaine (6, 11), qui comprend un boîtier (1) présentant une cavité (3) et une crémaillère (4) guidée coulissante dans ladite cavité (3). Le boîtier (1) et la crémaillère (4) sont accouplés chacun à un élément émetteur (14) et à un élément récepteur (16), par l'intermédiaire d'un câble sous gaine (6, 11). Lorsque l'élément émetteur (14) est activé, le boîtier (1) et la crémaillère (4) peuvent être accouplés à l'aide d'un mécanisme de transmission. Lorsque ledit élément émetteur (14) est désactivé, la crémaillère (4) soumise à une précontrainte peut être déplacée pour raccourcir le dispositif afin de compenser tout jeu relatif au boîtier (1), intervenant éventuellement dans le système.
