Definitions

  • the invention relates to a roll control actuator for installation between two axially aligned rods, in particular between two rods of a stabilizer, with a cylindrical housing and a housing arranged in the device for providing a on at least one of
  • Such a roll control actuator which is known from GB 2 350 592 A, is used in roll control systems in which the stabilizer is divided into two rods each coupled to a wheel of the vehicle.
  • the roll control actuator torque between the two rods which counteracts the forces introduced via the wheels, thereby stabilizing the vehicle.
  • the object of the invention is to provide a more easily constructed and thus less expensive manufacturable roll control actuator.
  • the invention provides in a roll control actuator of the type mentioned above, that the device comprises at least one first piston displaceable in the housing with a first piston rod, which is provided with a first thread, at least one first ball nut rotatably mounted in the housing, via a first thread mating first mating thread is in engagement with the first piston rod and is coupled to one end of a first rod, and comprises a first pressure chamber acting on a first side of the first piston.
  • This structure provides for a translation of a linear motion generated by pressure into a rotational movement with a few simple components, so that in an efficient manner acting between two stabilizer bars torque can be provided.
  • Advantageous and expedient refinements of the roll control actuating drive according to the invention are specified in the subclaims.
  • FIG. 1 is a schematic sectional view of an inventive rolling control actuator according to a first embodiment
  • FIG. 2 is a schematic sectional view of a roll control actuator according to the invention according to a second embodiment.
  • a roll control actuator is shown, which is intended for installation between two axially aligned rods of a stabilizer (not shown).
  • the roll control actuator comprises a cylindrical housing 10 in which two pistons 12, 14 are received longitudinally displaceable.
  • the pistons 12, 14 are slidably mounted on a guide rod 16, which counteracts a rotation of the pistons 12, 14 relative to the housing 10.
  • On the opposite sides of the pistons 12, 14 piston rods 18, 20 are formed, which are provided with threads 22, 24.
  • the threads 22, 24 have with respect to the longitudinal axis L of the housing 10 oppositely directed slopes and engage in counter-thread 26, 28 of ball nuts 30, 32, which are rotatably arranged by means of suitable bearings 34 in the housing 10, but immovable in the axial direction.
  • the ball nuts 30, 32 are each coupled to one end of a stabilizer bar.
  • two fluid ports 36, 38 are provided, which open into a first pressure chamber 40 formed between the first piston 12 and the first ball nut 30 and into a second pressure chamber 42 formed between the second piston 14 and the second ball nut 32.
  • Another fluid connection 44 opens into a middle pressure chamber 46, which is formed between the two pistons 12, 14.
  • the pressure chambers 40, 42, 46 are sealed by sealing rings. If pressure is built up via the two fluid connections 36, 38 in the two pressure chambers 40, 42, the two pistons 12, 14 move linearly toward one another.
  • the guide rod 16 ensures that the movement of the pistons 12, 14 with respect to the axis L is substantially free of rotation.
  • the non-displaceably arranged in the axial direction ball nuts 30, 32 convert the linear movement of the pistons 12, 14 in rotational movements, whose directions are indicated by the arrows A.
  • the directions of rotation A of the ball nuts 30, 32 are directed opposite due to their different thread pitches.
  • a rotation of the ball nuts 30, 32 in the direction of the arrows B is achieved by a pressure build-up in the middle pressure chamber 46 via the further fluid connection 44.
  • the pistons 12, 14 move away from each other linearly, and the ball nuts 30, 32 are rotated opposite to the arrows A.
  • FIG. 2 shows an alternative embodiment of the roll control actuating drive, in which only one piston 12 and only one ball nut 30 are provided.
  • a first pressure chamber 40 which can be filled via a first fluid connection 18, is formed between the piston 12 and the ball nut 30.
  • a further pressure chamber 46 is formed, which is filled via the further fluid port 44.
  • the further pressure chamber 46 is bounded by an end-side housing wall 48, to which one of the stabilizer bars can be coupled.

Abstract

Mécanisme de régulation de roulis destiné à être monté entre deux barres à orientation axiale, en particulier deux barres d'un stabilisateur, qui comporte un boîtier cylindrique (10). Un dispositif destiné à fournir un couple de rotation agissant sur au moins une des barres est logé dans le boîtier (10). Ledit dispositif comporte au moins un premier piston (12) pouvant coulisser dans le boîtier (10) et pourvu d'une première tige (18) de piston dotée d'un premier filet (22). Ledit dispositif comporte en outre au moins un premier écrou sphérique (30) qui est monté rotatif dans le boîtier (10), qui se trouve en prise avec la première tige (18) de piston par l'intermédiaire d'un premier contre-filet (26) adapté au premier filet (22) et qui peut être couplé à une extrémité de la première barre. Ledit dispositif comporte en outre une première chambre de pression (40) agissant sur un premier côté du premier piston (12).
