Definitions

  • the present invention relates to a rotary actuator for moving a swivel swing door, particularly for vehicles, such as buses and trains.
  • the swivel swing door for a vehicle is connected by means of swivel arms to a rotary column and can be displaced, by a rotational and lifting movement of the rotary column, to a closing and locking position in which locking means of the door and swing frame are engaged.
  • the movement of the rotary column is carried out by means of a rotary actuator which comprises a linear actuator and a screw drive which turns the actuator linear movement into a rotary movement.
  • DE3705369 describes a know example of a rotary actuator for moving a swivel swing door in a vehicle, wherein the linear actuator comprises a fluid dynamic piston-cylinder unit and the screw drive is formed externally of the linear actuator and comprises a female screw member which accommodates a cam shaft by the interposition of a set of spheres.
  • the connection of the piston to the female screw member is carried out by means of a stem extending from the piston within the cylinder to the female screw member outside of the cylinder.
  • the spheres interposed between the female screw member and the cam shaft only partially work under rolling friction and cause a considerable amount of sliding friction which results in energy dissipation and wear phenomena, which, in turn, make it necessary to further increase both the drive stroke (due to a reduction in the thread pitch) and the cam shaft diameter.
  • the object of the present invention is thus to provide a rotary actuator for moving a swivel swing door, particularly for vehicles, such as buses, having such characteristics as to overcome the drawbacks mentioned with reference to the prior art.
  • a particular object of the invention is to provide a rotary actuator which is more compact in terms of length and/or width.
  • a still further object of the invention is to provide a rotary actuator having a simplified and sturdy structure which is efficient in terms of power consumption.
  • a rotary actuator for moving a swivel swing door, particularly for vehicles, said rotary actuator having the features of claim 1 and defining a rotation axis and comprising:
  • a rotary actuator 1 for moving a swivel swing door 2, particularly for vehicles, is generally referenced 1.
  • the rotary actuator 1 defines a rotation axis 3 and comprises a fluid dynamic linear actuator 4 with a cylinder 5 defining an annular pressure chamber 6 therein and an annular piston 7 accommodated within the pressure chamber 6 in a sliding manner parallel to the rotation axis 3.
  • the rotary actuator 1 further comprises a screw drive 8 with a stator 9 being fastened such as not to rotate about the rotation axis 3 and connected to the piston 7 such as to translate together with the piston 7 in a direction parallel to the rotation axis 3, as well as a rotor shaft 10 engaged with the stator 9 by means of one or more revolving members 11 and configured such as to rotate about the rotation axis 3 in response to the translation of the stator 9.
  • the rotor shaft 10 provides an inner surface 12 of the cylinder 5 and directly defines the pressure chamber 6, the piston 7 being in sealing sliding contact to the inner surface 12.
  • the rotor shaft 10 is co-axially integrated in the actuator fluid dynamic 4 and the inner surface 12 provides an inner circumferential surface of the annular pressure space 6.
  • the concentrical arrangement of the rotor shaft 10 within the linear actuator 4 relative to the annular pressure chamber 6 minimizes the outer diameter of the pressure chamber, with the axial pressure surface and diameter of the rotor shaft 10 being equal, and allows defining the annular pressure chamber 6 by means of a simple outer tubular wall 13 which is radially positioned outside the rotor shaft 10.
  • the fluid dynamic actuator 4 can be configured as a double-effect actuator wherein the pressure chamber 6 is divided by the piston 7 into a first pressure chamber 6A and a second pressure chamber 6B which are arranged on opposite sides of the piston 7.
  • the rotor shaft 10 can directly define a part of both first 6A and second 6B pressure chambers.
  • the translatable stator 9, the revolving members 11 and a cam surface 14 (or race) engaged by them are accommodated within the annular pressure chamber 6.
  • the area in which the translational motion is turned into a rotary motion is completely enclosed within the pressure chamber 6 of the fluid dynamic linear actuator 4, thereby allowing to provide one outer housing 15 only for the entire rotary actuator 1, the side and end walls thereof being capable of directly defining also the pressure chamber.
  • the revolving members 11 comprise a pin 16 being provided at the translating stator 9 and a bush 17 pivotally supported on the pin by means of the interposition of a set of (cylindrical) rolls and having a cam-follower surface 18 which engages by rolling contact the cam surface 14 provided in the rotor shaft 10.
  • the revolving members 11 are thus provided by (cylindrical) rolling bearings, the inner support thereof (pin 16) being connected to the stator 9 and the outer ring (bush 17) thereof forming the cam-follower surface 18 in contact to the cam surface 14 of the rotor shaft 10 or vice versa.
  • the orientation of the pin 16 or, in other words, the local rolling axis of the bush 17 is substantially radial relative to the rotation axis 3 which, in turn, corresponds to the longitudinal axis of the rotor shaft 10.
  • Two revolving members 11 may be provided in diametrally opposite positions relative to the rotation axis 3 or three revolving members with 120° angular pitch.
  • the cam-follower surface 18 is advantageously convex or rounded in the direction of the rolling axis to eliminate the sliding friction due to the rolling differential between the radially outer area of the bush and the radially inner area thereof.
  • the actuator 1 comprises an outer housing 15 provided by a tubular wall 13 and two opposite head walls 19 connected to each other and to the tubular wall 13 by means of a plurality of preferably three tie rods 20.
  • the head walls 19 radially support the rotor shaft 10, by means of roller bearings 21, and axially, by means of one or two axial roller bearings 22 enclosed within fifth wheels against which a shoulder 23 of the rotor shaft 10 is abutted.
  • the tie rods 20 axially extend at an angular pitch (either constant, e.g.
  • At least one, preferably both head walls 19 have a central hole through which at least one end 24 is extended, preferably both opposite ends 24 of the rotor shaft 10 outside the housing 15.
  • the ends 24 of the rotor shaft 10 can be either grooved or profiled such as to allow an integral connection with a swivel arm 25 of a door 2.
  • brackets 26 can be provided for securing the rotary actuator 1 to a utility, particularly a vehicle, for example a bus or railway wagon.
  • the piston 7 can comprise an annular body that can be either single-piece or made of several pieced joined to each other, which forms:
  • the translatable stator 9 can comprise a tubular portion that provides the stator and can be formed either as one piece with the piston 7 or connected thereto integrally in rotation (for example by means of a key 33).
  • an (annular) filling body 34 can be advantageously provided which is suitable to reduce, in this area, the volume that can be filled with pressure fluid, with the axial length of the end area ( Fig. 7,8 ) being equal. This allows a fast emptying and a fast pressurization of the fluid volume, e.g. compressed air in that area (for example, during the return-stroke of the piston), without any requirement of sealingly isolating the area from the remaining part of the pressure chamber.
  • the return stroke of the piston 7 can be obtained by means of pneumatic or hydrodynamic control (pressurization of the second pressure chamber 6B in the case of a double-effect actuator (shown in the drawings) or, alternatively, by means of a return spring acting on the piston (not illustrated).
  • the linear actuator 4 comprises a pneumatic dampening system that slows down the movement of the piston 7 when it enters an end-of-stroke area.
  • the cylinder 5 provides a first duct 35 for feeding and draining the pressure fluid, which communicates with a first opening in the pressure chamber 6 and a second feed and drain duct 36 communicating with a second opening in the pressure chamber, wherein the second duct 36 has a throttled section (by means of an adjustment screw 37) relative to the section of the first duct 35.
  • the piston 7 provides an isolating annular wall 38 which is adapted to sealingly engage an isolating annular seat 39 (which is possibly provided with a gasket) when the piston 7 enters the end-of-stroke area.
  • the isolation annular seat 39 extends between the first opening and the second opening such that, when the piston 7 enters within the end-of-stroke area, the engagement of the isolating wall 38 with the isolating seat 39 separates an air volume within the pressure chamber 6 from the first opening and forces it to pass only through the second opening and the second duct 36 with the throttling. Thereby, the speed of the piston 7 is damped when approaching the end-of-stroke thereof.
  • the second duct 36 is connected to the first duct 35 at a downstream location (drain direction) of the throttling, such as to allow a feeding and a pressurization of the pressure fluid (compressed air) through the first duct 35 and first opening, thereby avoiding any undesired slowing down during the initial phases of the movement of piston 7, and accordingly of the door being operated.
  • this concept and the structure of the pneumatic damper described herein can be similarly implemented in both pressure chambers 6A, 6B of a double-effect actuator.
  • the stator 9 moves past the end of the first length and enters a second length 42 of stroke intended to translate or lift the rotor shaft 10
  • the axial engagement between the revolving members 11 or the stator 9 and the stop surface 40 causes the rotor shaft 10 to translate axially along with the stator 9 until the total end-of-stroke is reached (represented in Fig. 9 by the abutment surface 43 for example of an upper fifth wheel 22.
  • the axial translation of the rotor shaft 10 results to be prevented from the gravity force applied for example by the door connected to the rotor shaft, by a return spring (not illustrated) biasing the rotor shaft axially from a stopped position or by a counter-surface being shaped such as to allow for the axial displacement of the rotor shaft 10 only to a predetermined angular position which corresponds to the completion of the rotational movement thereof.
  • the rotary actuator 1 provides both to rotation and translation of the rotor shaft 10 in two well-distinct steps, and then to the orientation, locking lifting and release lowering of the door to which it is mounted.
  • sensors of axial and angular positions can be mounted to the housing 15 of the rotary actuator 1 and interact to the end/s 24 of the rotor shaft 10 which project outwards from the housing 15.
  • sensors can comprise e.g. potentiometric, mechanic, optical ad/or inductive sensors.
  • the rotary actuator of the present invention has a number of advantages, particularly it has reduced axial and radial dimensions, a sturdy, though simplified and lightened structure as well as a high energy efficacy in turning the translational movement produced by the linear actuator into a rotational movement of the rotor shaft.
