Definitions

  • the invention relates to an actuator assembly for a drivebridge that is meant to be used particularly in connection with a trailer of a truck or a like and, which consists of a frame part that is coupled with a frame structure of the trailer in a turnable manner at a first link point, when viewed from the side.
  • the frame part is arranged turnable by means of actuator means, such as one or several hydraulic cylinders or like, by twisting the same with regard to the first link point, first of all to a standby position, against an inclined surface existing in the frame structure of the trailer, and on the other hand to a drive position, as an extension, being essentially parallelly with the inclined surface.
  • a traditional way to carry out an actuator assembly as mentioned above is e.g. as shown in figure 1 such that the frame part, acting as a lower part of a drivebridge, is coupled by a link mechanism by a lower edge of its end surface with a head of a push arm of a hydraulic cylinder.
  • This kind of a solution operates in practice so, that a hydraulic cylinder, which is first of all in its standby position in a so called lengthened position and on the other hand visible under the structures of the inclined surface of the trailer, pulls the frame part to a drive position so that it is essentially parallel with the inclined surface, whereafter the hydraulic cylinder is in a so called shortened position, whereby its push arm is drawn inside.
  • the actuator assembly according to the present invention is mainly characterized by that the actuator assembly is carried out by a link arm mechanism that is formed of at least two parts and coupled with the frame part in a turnable manner in at least two points, thus enabling opening of the frame part to its drive position by using push force of the hydraulic cylinder or like belonging to the actuator means .
  • the actuator assembly according to the invention it is possible to carry out use of a moveable frame part, thanks to a link arm mechanism with at least two parts, so that the hydraulic cylinder belonging to the actuator means and moving the same, is, when the trailer is being moved, in a standby position of the drivebridge in a so called shortened position, in which case it can be kept protected from the environmental conditions thanks to its push arm being drawn inside.
  • an advantage of the actuator assembly according to the invention is the fact that the components thereof may be placed thanks to the operating principle depicted above furthermore in a way that the frame part is being moved from the standby position to the drive position by the hydraulic cylinder by pushing the same so to say from above with regard to the first link point. Thanks to an advantageous link arm mechanism of the actuator assembly according to the invention, having at least two parts, it is also possible to exploit significantly longer lever arms compared to existing solutions, thanks to which the hydraulic cylinder may be dimensioned clearly smaller than at present.
  • the actuator assembly according to the invention has also such an advantage, that it does not require extra service and maintenance measures thanks to the fact that its components are both during a standby and drive positions placed totally internally, protected by the structures of the inclined surface of the frame structure and the frame part.
  • figure 1 is shown a traditional drivebridge with its actuator assembly during a standby and a drive position
  • figure 2 is shown a motion series of the functioning of the actuator assembly according to the invention, when moving the same from its standby position to a drive position, and

Abstract

L'invention concerne un actionneur monté pour pont de transmission, destiné à être utilisé notamment en rapport avec une remorque de camion ou analogue. L'actionneur monté, qui est constitué d'un châssis (1) articulé à une structure de châssis (R) de la remorque, peut pivoter sous l'effet d'un actionneur (T), tel qu'un ou plusieurs vérins hydrauliques ou analogues, par torsion (w) vers un premier point de liaison (N), d'abord relativement à une première position (I), contre une surface inclinée (V) située dans la structure de châssis de la remorque, et d'autre part relativement à une position d'entraînement (II) en prolongement, sensiblement parallèle à la surface inclinée (V). L'actionneur monté est mené par un mécanisme à bras articulé constitué d'au moins deux parties, et articulé au châssis (1) en au moins deux points (X, Y), ce qui permet d'ouvrir le châssis (1) pour le placer dans sa position d'entraînement (II) par une force de poussée (F) du vérin hydraulique (TI) ou analogue de l'actionneur (T).
