Definitions

  • the invention relates to a centrifugal governor according to the preamble of the independent claim.
  • a centrifugal speed governor of the generic type is already known (AT-A-286 030), which has two groups of centrifugal weights that can be switched off in succession.
  • the first group consisting of four flyweights is only effective in the idle control range, takes the same starting position in the idle position of the controller as the other flyweights effective in the final speed range and is intercepted by stops attached to the flyweight carrier after a predetermined swivel angle.
  • centrifugal speed governor In another centrifugal speed governor known from DE-B-1 200 063, this is equipped with two groups of differently designed centrifugal weights which already have stops of the same design in such a way that a stop ring is provided which is concentric with the axis of the centrifugal speed governor. In the end position, the essentially outermost radial contour of these centrifugal weights comes to rest against this stop ring in the one centrifugal weight group. In the other centrifugal weight group, however, this stop ring engages in a radial recess of these centrifugal weights, as seen in the starting position, so that the radial outermost contour radially projects significantly beyond this stop ring.
  • centrifugal weights also access a second adjusting sleeve, which is mounted on the actual centrifugal speed regulator adjusting sleeve, which is actuated by the former centrifugal weights, and which is coupled to this sleeve via a spring.
  • the known centrifugal speed governor has the disadvantage that it takes up a considerable amount of space in the radial direction, the one centrifugal weight group not making much use of the working capacity that can be achieved with a given diameter.
  • the present invention has the purpose, particularly for use in idle speed governors for vehicle diesel engines, to improve a centrifugal speed governor in such a way that the possible centrifugal force radius is optimally utilized and thus a necessary multiplication of the centrifugal weights effective in the idle control range is avoided compared to the other centrifugal weights working only in the final speed range becomes.
  • the centrifugal speed governor according to the invention with the characterizing features of the independent patent claim has the advantage that the centrifugal weights effective in idling control, due to their outer contour shifted to the outside, exert a stronger centrifugal force at low speeds due to the correspondingly increased centrifugal force radius than known, from the inner position, with identical stops centrifugal weights only pivoting outward by the idle swivel angle.
  • the outermost swivel position which is determined by the maximum permissible centrifugal diameter, is optimally used for the centrifugal weights effective during idle control to achieve the greatest possible centrifugal force.
  • centrifugal force speed controller as is known from the publication mentioned at the outset, is provided with the same centrifugal weight masses on all centrifugal weights, then there is an optimal design and advantageous use of the centrifugal forces available through the characterizing features of claim 2.
  • centrifugal speed controller An embodiment of the centrifugal speed controller according to the invention is shown in the drawing in a longitudinal section and is described below.
  • centrifugal weight carrier 12 of a centrifugal weight regulator 13 On a as the drive shaft of the controller Ending camshaft 10 of an injection pump for injection internal combustion engines, not shown with the exception of a control rod 11, a centrifugal weight carrier 12 of a centrifugal weight regulator 13 is attached. Because of the high masses to be accelerated, the centrifugal weight carrier is fastened to a shaft stub 19 of the camshaft 10 projecting into the interior of the controller housing 18 by means of a vibration damper 14 containing a rubber element 14a by means of cover plates 15 and 16 and a round nut 17.
  • the centrifugal weight carrier 12 contains four bearing bolts 21, of which two bolts, each offset by 90 degrees, are shown in section in the drawing, and each form a pivot bearing for one of the angular centrifugal weights denoted by 22 and 23.
  • the centrifugal weight 22 represents one of two centrifugal weights which are effective only in the idle control and consists of a centrifugal weight 22a and a pressure arm 22b arranged approximately at right angles to it. To simplify the drawing, the second centrifugal weight 22 opposite this centrifugal weight 22 is not shown, in its place one of the centrifugal weights 23, which are in themselves offset by 90 degrees to the centrifugal weights 22, are shown, which are also effective in idle control only in the final speed control . Its centrifugal weight is designated 23a and its pressure arm 23b.
  • the two pressure arms 23b of the centrifugal weights 23 are drawn in the correct position in cross-section, based on the representation of the centrifugal weight 22, and lie against an end face 24 of a regulator sleeve 25 at least in the idle control range.
  • the end face 24 is formed by a thrust bearing 26 fastened to the regulator sleeve 25, and all the pressure arms 22b and 23b of the flyweights 22 and 23 take the same position in the illustrated zero position of the flyweights 22 and 23, which extends at least approximately perpendicular to an axis of rotation A of the regulator Starting position.
  • the axis of rotation A is also the longitudinal axis of the drive shaft 10 and the regulator sleeve 25.
  • the centrifugal weight carrier 12 is provided with the same stops 27 for all centrifugal weights 22 and 23, against which the centrifugal weights 22 and 23 come to rest in their outermost, pivoted position determined by a maximum permissible centrifugal circle diameter D F.
  • This outermost swivel position of both centrifugal weights 22 and 23 is indicated by dash-dotted lines, and the idle swivel angle corresponding to an idle sleeve path H 11 of regulator sleeve 25 is designated by all and, to simplify the drawing, is shown as a swivel angle of an outer contour 22c of centrifugal weight 22.
  • the outer contour 22c lies in the outer position shown in dash-dot lines with 22c ', which according to the invention forms the centrifugal circle diameter D F.
  • An outer contour of the centrifugal weight 23 is correspondingly designated 23c and passes through a total swivel angle a max which is proportional to the maximum sleeve path not shown and, after this swivel angle, assumes its outer position indicated by dot-dash lines 23c '.
  • the flyweight mass 22a is as large as the flyweight mass 23a, but it has already been moved outwards in the rest position shown so that the outer contour 22c is inclined to the axis of rotation A with an inclination angle ⁇ LL corresponding to the idle pivot angle a ll .
  • This embodiment variant is shown in dash-dot lines and the associated flyweight mass has been designated 22a 'and its inner contour 22d'.
  • flyweight masses 22a of the flyweights 22, as shown in the drawing, are the same size as the flyweight masses 23a of the other flyweights 23, then these flyweight masses 22a already have a difference in angle ⁇ a between them in the rest position Total swivel angle ⁇ max and idle swivel angle a LL swung outward starting position.
  • This angle difference ⁇ a can be read from the angle of inclination which the inner contour 22d of the centrifugal weight 22 assumes in the initial position shown with reference to the axis of rotation A.
  • the flyweight controller 13 described can be used in various types of idle speed controller, the most important components of an idle speed controller provided with a leaf spring 28 are shown to illustrate the controller function.
  • the position of the control rod 11 can be arbitrarily changed in a manner known per se by means of an adjustment lever arrangement 36 which can be pivoted about a pivot axis 33 in the controller housing 18 and engages via a pin 34 in a link guide 35 of the control lever 31.
  • governor sleeve 25 reaches after covering the idle sleeve path H ll at one adjustably mounted in a power transmission lever 38 stop 39 to the system and adjusts the transmission lever 38 after reaching the final speed against the force of a main control spring 41 and does not suggest that designated maximum sleeve path back.
  • the control rod 11 is moved in the direction of an arrow 42 into its stop position.
  • the centrifugal force ratio is reduced from 1:70 to 1:30, and with a correspondingly increased centrifugal weight 22 to the centrifugal weight 22a ', an even smaller centrifugal force ratio can be achieved.
