Definitions

  • the present invention relates primarily to a hydraulic actuation system. Furthermore, the present invention also relates to possible applications for the hydraulic actuation system, such as a brake system for roller skates, so-called inline skates. Furthermore, the present invention also relates to a braking system for rollers, preferably for rollers of inline skates, which provides an anti-rattling or anti-blocking function and in which the hydraulic actuation system mentioned can be used.
  • Conventional power-way transmission systems include, for example, gears or connecting rods. With flexible force-displacement transmission there are the widespread cables in the lower price segment and hydraulic systems in the upper price segment.
  • Cable pulls are simple and inexpensive to manufacture, but they have various disadvantages. It can only be operated when it is pulled, but not when it is pushed. The power transmission is associated with particularly high friction losses. Branching is extremely difficult and difficult to produce. Control, regulation and blocking options are practically non-existent.
  • Kotben-cylinder arrangements are usually used as actuating or working elements, which require a large number of parts, in which sealing between the piston and the cylinder is required and which inherently require a complex construction and a relatively large size.
  • a hydraulic actuation system with at least one actuating / working element, in such a way that a self-contained compressing / expanding volume is produced in one piece by suitable material, hardness and geometry, so that de compression / expansion is determined in de direction of actuation goes
  • the actuating / working element has a connection for connection to a line and a main body, which forms a connection to the connection, otherwise closed chamber for receiving hydraulic fluid and a substantially cylindrical, axially extending outer wall and two in has substantially flat, substantially perpendicular to the outer wall end walls at least one of the end walls is designed such that at least a part of it is deflected axially when the pressure of hydraulic fluid in the chamber changes.
  • the end wall consists of an alternating arrangement of relatively rigid, shape-retaining troughs and relatively elastic, giving-away parts, the end wall preferably being circular and of an alternating concentric arrangement of at least one relatively elastic, giving-away ring and a relatively rigid, shape-retaining, circular middle section.
  • the end wall can also have at least one relatively rigid, shape-retaining ring and at least two relatively elastic, giving away rings.
  • the main body may also have a through opening defined by a substantially cylindrical inner wall extending in the axial direction and disposed radially inward of the outer wall.
  • the end wall is then preferably ring-shaped and consists of an alternating concentric arrangement of at least one relatively rigid, shape-retaining ring and at least two relatively elastic, giving away rings.
  • the outer wall of the main body is designed such that it forms a circumferential radial groove or groove while the material thickness remains essentially the same
  • the actuation / work element is preferably made in one piece, which ensures a simple construction. It is preferred that the actuating / working element consists of an elastomer or an elastic thermoplastic, for example with a hardness of SS 0 'Shore (A).
  • a particularly inexpensive manufacturing process for the actuating / working element is the injection molding process. However, other methods are also possible.
  • actuation / working element which is normally connected to a line carrying hydraulic fluid and has the following: a connection for connection to the line, and a main body, which is connected to the connection, the other closed chamber for receiving hydraulic fluid and has a substantially cylindrical, axially extending outer wall and two substantially flat, substantially perpendicular to the outer end walls, at least one of the end walls being designed such that at least a part thereof when there is a change in pressure from hydraulic fluid in the chamber is axially deflected.
  • the end wall preferably consists of an alternating arrangement of relatively rigid, shape-retaining parts and relatively elastic, giving away troughs, the end wall preferably being circular and consisting of a concentric arrangement of at least one relatively elastic, giving away ring and a relatively rigid, shape-retaining, circular middle part

  • the hydraulic actuation system is filled with hydraulic fluid and has the following. at least one actuating element that can cause a pressure change in the hydraulic fluid when actuated, at least one working element that can be deflected in response to the pressure change in the hydraulic fluid, and a connecting line for hydraulic fluid that connects the actuating element and the working element to one another
  • This simple hydraulic actuation system is versatile, very reliable and comparatively extremely inexpensive to manufacture.
  • the actuating element and the working element can be designed identically.
  • a valve can be provided in the simplest way, which can control or block the flow of hydraulic fluid through the connecting line. If, for example, the connecting line is an at least partially elastic connecting hose, the valve can have at least one eccentric with which the connecting hose can be clamped.
  • a modular hydraulic system results from the previously mentioned parts and possibly also other or further parts.
  • the different elements can be easily combined. Actuating elements or working elements can be connected to a connecting line by simply plugging and dressing using a fastening ring. Branched systems or multi-circuit systems can be set up in the simplest way.
  • the elements of the modular hydraulic system can be standardized, so that there are favorable manufacturing requirements and storage conditions.
  • the hydraulic actuation system according to the invention as well as the actuation / working element mentioned can preferably be used in a brake system for rollers or wheels, in particular for rollers or wheels of inline skates.
  • Brake pad attached to the wheel of an inline skate for example made of rubber.
  • the conventional braking options with inline skates are very inadequate and prone to accidents.
  • the relevant inline skate or roller skate has to be tilted backwards, which means that practically only the other shoe is used, which is especially difficult for beginners and often leads to falls and injuries, even with optimal ones Mastering the inline skates can only be achieved with the conventional brake block to a small extent, especially on wet or uneven surfaces.
  • the brake pad is also subject to high wear and must be replaced relatively often.
  • the conventional braking system consists of many parts, some of which are attached in a complicated manner, for example by joints, to the inline skate or roller skate.
  • the brake pad is also geometric strong front end, ie it protrudes backwards, which can often be a hindrance. Therefore, the brake pad is often dismantled, which increases the danger of in-line skating
  • the hydraulic actuation system as well as the brake system according to the present invention avoids all previous disadvantages. It offers a technically perfect brake or a technically perfect one
  • Actuating system with a simple, inexpensive to manufacture, closed system In contrast to a conventional actuation by means of a cable pull, the system according to the invention has practically no internal friction and branching is easily possible for multiple actuations or multi-circuit systems.
  • the system according to the invention is wear and maintenance-free, has a long service life, offers high security, consists of a few parts, can also be retrofitted if necessary, is small, compact and easy to integrate. Due to the closed system, there is no leakage liquid either. In short, the present invention offers high tech at low cost.

Abstract

L'invention concerne principalement un système de commande hydraulique; les utilisations dudit système, telles que système de freinage pour patins à roulettes de type patins à roues alignées ; et un système de freinage pour roues, de préférence pour roulettes de patins à roues alignées, qui comporte une fonction anti-aplatissement ou anti-blocage et dans lequel ledit système de commande hydraulique peut être utilisé. Le système de commande hydraulique, qui comprend au moins un élément de commande/travail, est configuré de façon à former un volume fermé d'une seule pièce qui est alternativement comprimé/dilaté et dont le matériau, la dureté et la géométrie permettent une compression/dilatation ciblée dans la direction d'actionnement.
