Definitions

  • the present invention relates to an improved mechanical cylinder for motor vehicles, for raising and lowering them in order to replace the corresponding damaged wheel, normally by puncture or cutting of its tire and said cylinder provides, for the function for which it is intended , several advantages which will be noted below, apart from others inherent in its constitution.
  • the rear lower arm (2) which starts from the rear apex of the parallelogram of the jack, has a lower extension (2a) which forms the support leg of the jack itself, separating the parallelogram from the ground and is articulated to a foot (10 ) to rest on the ground or corresponding surface.
  • the upper front arm (4) may incorporate a dowel or similar elastic (not shown), disposed at the part of the front end of said arm and near the front apex of the parallelogram, in correspondence with a tubular part (11) of the stirrup ( 8), which is freely articulated with clearances in all directions around an axis (12), which is connected to the extension of the rear upper arm (1) of the parallelogram, said axis (12) possibly consisting of a rod fixed - for example by riveting or by welding - to the curved end of said extension of the rear upper arm (1), but in any case there must be a free articulation with a relatively large clearance between the tubular part (11) and the axis (12).
  • the proper configuration of the centering device (7) gives rise to its very simple assembly, consisting of a single piece and it requires less labor for its installation, which represents a lower cost of the jack, and it should be noted that the worker only has to present and locate said centering device in the desired place for its union with the stirrup, with self-positioning of said centering device between the side walls or parallel wings of the extension of the arm (1 ) on which it is installed, at the same time eliminating possible mounting errors and making it easier, by obtaining moreover a correct automatic centering of the caliper and an optimal balance of the jack, ensuring the stability of the 'assembly formed by the cylinder and the vehicle to which it is applied.

  1. Verbesserter Wagenheber für Kraftfahrzeuge, mit vier untereinander gelenkig verbundenen und in Form eines Parallelogramms angeordneten Armen (1, 2, 3, 4), versehen mit einer in einer Diagonalen angeordneten Spindel (5), mit dessen hinterem Ende ein Mittel (6) verbunden ist, um es zu verschwenken, sowie versehen mit Mitteln zum Halten, vorzugsweise durch ein Lager, sowie Mitteln zum Verschrauben, wobei die Haltemittel und die Verschraubmittel an der vorderen und der hinteren Spitze des Parallelogramms angeordnet sind und der Wagenheber an der oberen Spitze des Parallelogramms einen Bügel (8) für das Halten und das Tragen des entsprechenden Kraftfahrzeugs aufweist, während der untere Arm (2) des Parallelogramms, der von dessen hinterer Spitze ausgeht, unten verlängert ist und das Trägerbein (2a) des Wagenhebers bildet, das für seine Abstützung am Boden an einen Fuß (10) angelenkt ist, und wobei der Bügel (8) einen rohrförmigen Abschnitt (11) aufweist, der mit großem Spiel in alle Richtungen um eine Querachse (12) an der Verlängerung des hinteren oberen Armes (1) des Parallelogramms frei angelenkt ist, und wobei der obere Abschnitt des hinteren Querschenkels des Profils des Bügels (8) in der Nähe der Öffnung und als Teil von ihr eine Zone (14) in Form einer nach hinten geneigten Ebene aufweist, dadurch gekennzeichnet, daß der Bügel (8) mit der unteren Seite seines vorderen ebenen Abschnittes verbunden eine lamellenartige Zentriervorrichtung (17) aufweist, die federnd ist und allgemein die Form eines umgedrehten "U" aufweist, dessen Steg mit dem Bügel (8) verbunden und quer zu dem Bügel angeordnet ist sowie bestimmt ist durch ein längliches und ebenes Mittelteilstück (18), das an jedem Ende durch einander gegenüberliegende und zueinander symmetrische kurze geneigte Teilstücke (19, 20) nach unten und außen verlängert ist, von denen jedes wiederum eine seitliche, ebene und vertikale Verlängerung (21, 22) aufweist, die einen länglichen Abschnitt mit zur unteren Seite des Bügels senkrechter Achse aufweist, mit einer länglichen Öffnung (23), die im wesentlichen mit der Innenöffnung des rohrförmigen Abschnittes (11) des Bügels (8) übereinstimmt, so daß die beiden seitlichen und zueinander parallelen Verlängerungen (21, 22) der Zentriervorrichtung (17) sich an den entsprechenden Innenflächen der beiden zueinander parallelen Flügel der Verlängerung des hinteren oberen Armes (1) abstützen, und daß der Bügel (8) sich mittels wenigstens einer Feder (26) und bezüglich der Verlängerung des Armes (1), an dem er angelenkt ist, hinsichtlich seiner relativen Schwenkbewegung in einer Zwischenstellung bezüglich der von den beiden Endanschlägen der Verlängerung (21, 22) bestimmten Stellungen hält.
