  • adjusting element is to be understood broadly in the present case. It includes, for example, flaps such as tailgates, trunk lids, engine hoods, side doors, cargo space flaps or the like, or sliding doors of a motor vehicle.
  • a motor-driven drive is, for example, a spindle drive which, via a drive motor, drives a spindle-spindle nut gear as a feed gear to generate linear drive movements.
  • a motorless drive has in particular a gas pressure spring which has a drive unit with a gas-filled gas pressure spring cylinder and a gas pressure spring piston rod axially guided therein, that is to say a push rod with a piston at the end. The gas filled into the cylinder is then pressurized and thus provides the spring force.
  • This drive unit can additionally be supported by a drive spring arrangement with at least one drive spring, in particular a helical spring, for example a helical compression spring, which provides an additional spring force.
  • the known drive (DE 10 2008 061 117 A1) on which the invention is based has such a drive unit in the form of a gas pressure spring.
  • the drive unit is surrounded radially by a drive spring arrangement with a drive spring in the form of a helical compression spring.
  • the drive has two joint parts adjustable to one another along a geometric drive axis between a retracted position and an extended position, each with a counter-joint part on the vehicle side, a drive connection for coupling with the adjustment element on the one hand and the motor vehicle otherwise, on the other hand, form.
  • One joint part is with a hollow cylinder the drive unit, namely the gas pressure spring cylinder, and the other joint part is axially fixedly coupled to a rod of the drive unit, namely the rod provided with the gas pressure spring piston.
  • a metal plate is provided between the respective joint part and the drive unit, on which the drive spring of the drive spring arrangement is axially supported in order to transmit the spring force to the joint parts.
  • the drive housing which is made of a plastic material, is angled inwards at the two axial ends and thus forms a base which secures the respective metal plate towards the joint part against the spring force of the drive spring arrangement.
  • the two joint parts themselves, which are each coupled to the associated component of the gas pressure spring, that is to say the gas pressure spring cylinder on the one hand and the gas spring piston rod on the other, form a further axial safeguard when mounted on the motor vehicle.

  • These metal bodies are then usually overmolded with plastic material to form the associated joint part.
  • a corresponding drive has a relatively complex structure and has a large number of parts.
  • the invention is based on the problem of designing and developing the known drive in such a way that a high level of operational reliability is ensured with a simple structure at the same time.

Rather, the clip has two legs which, like the ends of a snap ring, can generate a clamping force on each other when they are pushed apart from the unloaded state.
  • Claim 3 relates to an axial extension which is provided on the hollow cylinder forming one component of the drive unit and which serves to hold the form-fitting element, in particular the clamp, in an axially form-fitting manner in the assembled state.

Abstract

L'invention concerne un mécanisme d'entraînement permettant de déplacer un élément mobile (2) d'un véhicule à moteur (3), ledit mécanisme d'entraînement (1) présentant une unité d'entraînement (4) qui comporte comme composants transmettant une force d'entraînement un cylindre creux (5) et une tige (6) guidée axialement dedans, ledit mécanisme d'entraînement (1) comportant pour transmettre des mouvements d'entraînement linéaires au véhicule à moteur (3), deux parties articulées (8, 9) qui forment dans chaque cas un raccord d'entraînement (12, 13) avec une partie articulée antagoniste (10, 11) située côté véhicule à moteur, à l'état monté, une partie articulée (8) étant accouplée de manière fixe dans le sens axial avec un premier des composants (5, 6) et l'autre partie articulée (9) étant accouplée avec un second des composants (5, 6) dans chaque cas, et le mécanisme d'entraînement (1) présentant un ensemble ressort d'entraînement (14) doté d'au moins un ressort d'entraînement (15) qui agit sur les deux parties articulées (8, 9). Selon l'invention, à l'état monté, au moins un des composants (5, 6) de l'unité d'entraînement (4), en particulier les deux composants (5, 6) de l'unité d'entraînement (4), et la partie articulée antagoniste (8, 9) associée dans chaque cas, sont accouplés axialement les uns aux autres par complémentarité de forme, par l'intermédiaire d'un élément à complémentarité de forme, en particulier dans les deux directions axiales, et l'élément à complémentatité de forme (16) fait saillie radialement dans une projection axiale (P) du matériau élastique de l'ensemble ressort d'entraînement (14).
