Definitions

  • the present invention refers to a tensioning element for brake cables of motor vehicles, applicable to the parking or handbrakes that these vehicles are equipped with, which are self-adjusting as regards the cable, in the face of the frequent tension losses of the same that runs from the tensioner to the wheel brakes.
  • 4,753,123 which refers to a self-adjusting cable mechanism for clutches or the like, has a threaded slide on which a member acts, which is disconnected from the slide by the action of another part that has a conical extension that acts against a also conical portion of the limb in question.
  • EP-A-0 754 135 a self-adjusting mechanism with a slide and two wedge pieces is known, in which two different springs intervene, as well as two also different covers and a widened area in the slide.
  • the two stops are used which act, successively, against the wedged parts and against a connected fork associated with the receiver of the lever arms.
  • the widened pressure of the slide also acts against the wedged parts after the action of the mentioned stops.
  • This mechanism is relatively complicated by its assembly and by the number of different parts it needs to incorporate.
  • Aims of the present invention are a self-regulating device for handbrake cables that is simpler and has a low number of components.
  • Another object of the invention is a self-regulating tensioner for parking brake cables, the assembly of which is convenient and economical.
  • Another object of the invention is a self-regulating tensioner for handbrake cables that effectively and simply ensures the effective separation of the wedged parts in relation to the slider, avoiding any possibility of permanent braking of the assembly when the brake lever is released.
  • the invention claims the structural modification of the different components included in the aforementioned EP-A-0 895 909 and the provision of an opening piece for the wedged pieces.
  • a slider with circular cross-section provided with teeth is established, with a front end in which the cable that goes to the towline, connector ... etc. is fastened, for its arrival at the vehicle wheel brakes. , whose tension of said cable is the one that the set tries to regulate itself.
  • the rear end of the slide receives a stop piece on which the end of a coil spring that surrounds the slide rests.
  • the quoted spring is collected between two semi-shells, based on two longitudinal bodies equipped with semi-cylindrical housings and with U-shaped cross sections.
  • the edges of the wings of both bodies are provided with protruding pins and blind holes that receive them. , respectively, so that they can be accommodated with one another by clips, with the particularity that the rear end of the assembly serves as a support for the aforementioned rear slide cover.
  • two lateral wedge-shaped outer pieces are arranged, which are placed facing each other, being provided on the facing faces with semi-cylindrical spaces provided in correspondence with the teeth of the slide.
  • the two wedged pieces show projections on the top and bottom which are housed with some clearance in corresponding windows made in the front portions of the two longitudinal bodies.
  • the spring is placed on the slide, at its rear, positioning the spring stop at the rear end.
  • the two are located in front of the pier wedged parts, so that the spring being under a certain tension, the two outer bodies that clip together are placed on the spring and the wedged parts, whereby the spring and the wedged parts are perfectly pre-assembled.
  • the wedged pieces protrude with their projections, up and down, with some clearance, and the top of the spring rests on the rear part of the meeting of the two longitudinal bodies.
  • an opening piece of the two wedged pieces is mounted on the slide prior to the placement of the spring, this opening piece having a large hole through which the said slide freely circulates.
  • the pre-assembled set is subsequently housed inside a generally U-shaped housing whose ends of its wings are bent in contrast.
  • each set of projections is received in each lateral hole of said cover by clipping, so that it is carried out very easily.
  • the cover on its side is equipped on its sides with facing collars to tie the bottom of the brake lever.
  • the front part of said cover is made with a narrowing that configures sloping wedge sides.
  • the slide protrudes logically from this front end of the cover, and the front parts of the two half-bodies between which the wedged parts are housed, also show their outer sides forming a wedge so that they fit perfectly to the front inside of the cover.
  • the opening piece is fixed to the support where the handbrake is secured, and it is a vertical piece which at its upper end has at least one horizontal projection that is substantially at the height of the inclined planes formed by the wedged pieces .
  • the opening piece is provided with two parallel projections, one above the height of the two upper inclined planes of the wedged pieces and the other below the height of the lower planes.
  • the ends of the projections are triangular, with rounded corners, and of little thickness, so that when the cover is moved forward actuated by the brake lever, they enter between the inclined planes of the wedged parts, establishing an action of the said projections against said surfaces which is such that they inexorably force the wedged parts to separate in unison from their contact with the slide.
  • the opening part When the opening part is provided with a single projection, it does not form part of the preassembly of the assembly described above, since the attack on the wedged parts is carried out only from the bottom.
  • the opening piece has two projections, it is provided with a hole for the passage of the slide, as previously indicated.

  • the two wedged pieces (18) are attached to this slide and below and above the two bodies (2, 3). These two bodies have internal holes (6) to receive the spring (22) and grooves (5) at their front ends (4) to receive the projections, upper and lower (19) of the wedged pieces (18), which enjoy of some slack.

  • the opening piece (14) does not include more than one projection, the lower one, it is not included in this pre-assembly. It is appreciated that the two bodies (2, 3) are provided with pairs of lateral projections (25), which when closing both bodies, will constitute a joint projection.
  • the assembly thus made is subsequently housed inside the cover (11) with a U-section and with the ends of its wings in contrast, which is provided with a front portion (24) that narrows providing internal walls ( 17) wedge, in which the outer faces (21) of the wedged pieces (18) will slide.

  • the opening piece When the opening piece has a single tab, fig. 6 a , it is located directly on the base of the brake assembly and its contact is made only in relation to the lower projections of the wedged parts. In this particular case, the opening part does not participate in the pre-assembly reflected in fig. I a .
