Definitions
- the present invention is in the technical field of transmission technology and relates to a motion with a switching shaft of a gearbox coupled additional mass.
- switching shafts in the gearbox are displaceable along their longitudinal center axis and arranged rotatable about this axis. By moving and turning the stem, the aisles can be selected or the gears can be switched.
- an additional mass to increase the moment of inertia of the shift shaft this is coupled via a driving mechanism so with the shift shaft that it is taken either at an axial displacement of the shift shaft or during its rotation.
- the additional mass is attached to a boom which is mounted pivotably about a pivot axis in the manual transmission.
- Such additional mass is described for example in German Patent DE 195 46 547 C1. In the switching device shown there, the additional mass is pivotally mounted via a boom.
- a coupling rod is articulated on the one hand to the boom of the additional mass and on the other hand with a rotatably connected to the shift shaft shift lever, which in turn is operatively coupled to a manual shift lever for manual operation by the driver. If the selector shaft is rotated, the boom together with additional mass is rotated along the coupling rod with the selector shaft, so that the moment of inertia of the selector shaft is increased when turning.
- Additional masses is available in the manual usually relatively little space available, which also usually imposed on them a complex spatial form. To protect additional masses from corrosion, it is necessary to coat them with a corrosion protection layer. Since the corrosion protection layers used in this case are generally sensitive to heat, additional masses are usually produced by casting and then coated with a corrosion protection layer ü, which is applied for example by electroplating. The disadvantage here is in particular the fact that the corrosion coating penetrates into the resulting pores of the cast material (cast iron) during casting.
- the object of the present invention is to provide an immovably coupled with a shift shaft of a gearbox additional mass available, which can be prepared without a casting process.
- the additional mass is composed of a carrier element which is pivotably mounted in the installed position about a pivot axis and at least one inertia element which is spaced apart from the pivot axis and is fixed in a form-locking and / or force-locking manner on the carrier element.
- the carrier element is advantageously formed in an elongate shape and thus forms a cantilever for the at least one inertial mass.
- the support member may be mounted in the installed position at one of its two ends or end portions pivotable about a pivot axis in the manual transmission. Similarly, it is possible that the support element with a between its two ends or Endab- cuts located pivot axis about this axis is pivotally mounted in the manual transmission.
- the carrier element is designed as a band-shaped flat profile.
- the at least one inertia member is attached, for example, to at least one end portion of the elongate support member.
- the carrier element may in particular be designed such that in the installed position it comprises two legs directed away from its pivot axis, wherein in particular each leg of the carrier element may be provided with at least one inertia element.
- the additional mass can furthermore be designed such that its center of mass coincides substantially with the pivot axis provided in the installation position.
- a connection between the carrier element and the at least one inertia element can be realized, for example, by means of at least one passage, which breaks both the carrier element and the at least one inertia element in an aligned manner, and a pressing element introduced into the force and, optionally, positive locking manner.
- the at least one inertia element is rotationally fixed with respect to the carrier element attached to this in order to avoid a change in the mass moment of inertia of the additional mass due to a change in position of the inertial element relative to the carrier element in a pivoting of the additional mass.
- the carrier element and the at least one inertia element are advantageously made of a metallic material.
- the invention further extends to a switching device for a manual transmission, which is provided with a rotatably and axially displaceably received in the manual transmission shift shaft.
- the switching device is provided with a rotatably connected to the shift shaft shift lever, which is coupled with a manually operated by the driver manual shift lever (kinematically).
- the switching device is equipped with a force acting on the shift lever according to the invention additional mass, which increases the moment of inertia of the shift shaft such that force peaks of the shift lever measurable switching power can be reduced during individual switching operations.
- the additional mass may for example be mounted pivotably on the housing of the gearbox or on the shift shaft.
- a coupling with the shift lever can be done for example via a hinged both on the shift lever and on the additional mass, for example by means of respective ball joints coupling rod.
- the additional mass is coupled via a driving mechanism with the shift lever so that it is moved only with a rotation of the shift shaft (corresponding to an engagement movement for shifting the gears) with the shift shaft.
- Fig. 1 is a perspective view of an embodiment of the additional mass according to the invention.
- Fig. 2 is a partial perspective view and partially cut
- FIG. 1 shows an embodiment of the additional mass according to the invention for a shift shaft of a gearbox.
- FIG. 2 shows the additional mass of FIG. 1 in a partially perspective view corresponding to the side facing away from the observer in FIG. 1 and a partial section along a longitudinal center line of the additional mass.
- the additional mass is denoted overall by the reference numeral 1. It comprises a band-shaped first flat profile 2 serving as a carrier element, which is rectangular in plan view and formed in the spatial form as a cuboid with wide surfaces 11 and narrow surfaces 12.
- the band-shaped first flat profile 2 can be mounted pivotably about the pivot axis 3a by means of a pivot bearing 3 in a manual transmission, for example on the transmission housing or on the control shaft.
- the pivot bearing 3 is arranged on a longitudinal center line of the first flat profile 2 in an approximately central position between the two end faces 9 of the flat profile 2, so that the first flat profile 2 comprises two each directed away from the pivot bearing 3 legs 2a, 2b.
- the first flat profile 2 is provided with a section 7 which is curved in the form of an S-beat perpendicular to the wide surfaces 11 of the flat profile 2 and which conveys the additional mass to the available adjusting space in the manual transmission adapts.
- the first flat profile is made for example of sheet steel.
- a second flat profile 4 serving as an inertia element 4 is fastened on the wide surfaces 11 opposite each other, which are all equal to one another.
- Each inertia element is formed in the plan in something rectangular and in the spatial form as a cuboid with wide surfaces 14 and narrow surfaces 10.
- the second flat sections 4 are each arranged at one end portion of the legs 2a, 2b with their long sides transverse to the first flat profile 2, wherein the narrow surfaces 10 of the second flat sections 4 are flush with the end faces 9 of the first flat section 2 approximately.
- the flat sections 4 can be made for example of flat iron.
- a through hole 5 is formed, which in each case passes through the two opposite second flat profiles 4 and the first flat profile 2 located between them.
- a pressing bolt 13 with a small overlap is press-fit, so that the two opposing second flat profiles 4 and the first flat profile 2 located between them are connected to one another in a force-locking and form-fitting manner.
- a respective depression 6 is formed on the broad sides 14 of the second flat sections 4, which in a corresponding manner each associated with a first flat profile 2 projection 15, the in a corresponding depression of the first flat profile 2 engages.
- the opposing depressions 6 and corresponding projections 15 can be produced at the same time, for example, by means of a collet pressing and serve as an anti-rotation device for preventing rotation of the second flat profiles 4 relative to the first flat profile 2.
- the additional mass shown in FIGS. 1 and 2 is provided as part of a switching device of a gearbox, in particular for a motor vehicle, for motion-resistant, in particular rotationally fixed coupling with a switching shaft.
- the selector shaft is rotatably and axially displaceable in the gearbox (gearbox) added.
- the switching device is provided with a non-rotatably connected to the shift shaft shift lever which is kinematically coupled with a manually operated by the driver manual shift lever.
- the additional mass 1 acts by means of a driving mechanism on the shift lever, such that the mass moment of inertia of the shift shaft is increased so that power peaks of the shift lever measurable switching power can be reduced during individual switching operations.
- the additional mass 1 can be pivoted for this purpose by means of the pivot bearing 3 about the pivot axis 3a, wherein a storage of the additional mass 1 can be done on the gear housing or on the shift shaft.
- a coupling with the shift lever can be done for example via a coupling rod, which is articulated both on the shift lever and on the additional mass 1, for example, at the Drehmomenteinleitstelle 8, for example by means of respective ball joints.
- a coupling can be done for example via a cable (Bowden cable).
- the Drehmomenteinleitstelle 8 is arranged at a distance from the pivot axis 3a to initiate a torque in the additional mass can.
- the additional mass 1 is preferably coupled to the shift lever via the driving mechanism in such a way that it is moved along with the shift shaft only upon rotation of the shift shaft (corresponding to an engagement movement for shifting the gears). LIST OF REFERENCE NUMBERS
