Abstract
ABSTRACT OF THE DISCLOSURE
A selector detent means in a gear shifting device on, or in conjunction with, a rotating shaft, the axial displacement of which, from the neutral position, serves to select a gate, whereas the rotation thereof engages the gears. Arranged in the rotating shaft, or upon at least one locking ring, are locking paths which act only in the selecting direction and cooperate with at least one detent element guided in the control housing. Under the action of a spring, being against the control housing, the detent element is urged towards the locking path so that, under the action of the locks, a locking projection occurs which makes it easy for the driver to find the gates as he moves the gear shift lever. Under the additional action of a holding-coupling spring assembly, the gear shift lever is guided back into a predetermined gate or the detent elements are preferably designed pivotably, e.g. as detent levers, and are mounted upon a first pin secured, in the control housing, at right angles to the rotating shaft. A projection on the detent lever is in operative connection only with the locks of a detent ring and the pivoting movement of the detent lever is restricted by a second pin arranged in parallel with the first in an opening or elongated hole, in such a manner that a gap occurs between the projection and the bottom of the locking path or of the rotating shaft. As a result of the small amount of friction during the pivoting movement, and of the elimination of any friction outside the locks, the gear shift is smooth and of simple design.

Description
8~
The present invention relates to a selector detent means in a gear shift device on, or i:n conjunction with a rotating sha~t, the axial displacement of which, from : the neutral position, serves to select: a gate, whereas the rotation thereof engages the gears, locking paths bei.ng arranged in at least one locking ring secured to said ro-tating shaft, said locking paths acting only in the selecting direction, with at least one detent element which is guided in the control housing and which, under the action of the spring, is urged towards the locking path, a locking pro-jection, acting in the direction of selection, arising under the action of one or the other and making it easy for the driver to find the gates as he moves the gear shift lever and, under the additional action of a holding spring assembly, the gearshift lever being guided back into pre-determined gates and two d~tent elements being preferably arranged laterally of the rotating shaft and facing each : other.
: A device of this kind is known, for example from German patent 30 00 577, Figure 2, wherein spherical elements 7 cooperate with a control ca~ 80. Devices of this kind operate reliably and provide a locking projection which extends over the selector positions and makes it easy to find the gates. In conjunction with a holding spring as-; sembly, the rota-ting shaft is also held, or returned into, predetermined gate positions. As a result oi relatively considerable friction in the guidance of the spher.ical elements, the locking force in the selecting dlrection is dependent not only upon spring forces, but also upon produotion tolerances and -temperature. The production of a device of this kind is complex and it is therefore costly.
It is therefore an important ~im of the present in-vent.ion to optimize a selector detent meanc according to the afore-mentioned prior art device, from the point of view of fric-tion, with a view to obtaining smooth sh:ifting, but without impairing -the effect of the detent means~ Also, to provide a design of device which is simple and easily assembled.
The aforementioned aim is achieved by the present invention in providing a selector detent means in a gear shifting device on, or in conjunction with, a rotating shaft, the axial displacement of which, fro~ the neutral position, serves to select a gate, whereas the rotation thereof engages the gears, locking paths being arranged in at least one lock.ing ring secured to the rotating shaft, the locking paths acting only in the selecting direction, with at least one detent element which is guided in the control housing and which/ under the action of the spring, is urged towards the locking path, a locking projection, acting in the direction of selection, arising under the action of one or the other and ~aking it easy for the driver to find the gates as he moves the gear shift lever and, under the additional action of a holding spring assembly, the gearshift lever being guided back into predetermined ga-tes and two detent elements being preferably arranged laterally of the rotating shaft and facing each other, characterized in that the detent element is pivotably secured in the control housing, the pivoting movement thereof being restricted in a radially inner terminal position.
Whereas, according to the prior art, the detent element is guided radially and is a-t all times pressed by a spring against a locking path, which leads to relatively high friction, a tiltiny motion produces very little friction because the radius, around which the tilting motion occurs, may be kept very small. The Eriction also acts only during ~2~
a displacement/ e.g. during a double-H shi~t from the 3/4 gate to the 5/6 gate and possibly to the reverse gear gate.
In the case of displacements into the gates and gears of the remaining forward speeds 1/2, 7/8, there is no friction either in the shifting or the selecting direction because, since the detent element is locked in the radially inner position, there is no contact with the bottom of the locking path. The basic principle of this arrangement also permits a very simple and inexpensive design with reliable detent.
In addition to this, the reverse gear detent can also be included. In the case of German patent 30 00 577, (Figures 4 and 5), this requires separate detent elements 82.
In the case of the practical design, according to the preferred embodiments disclosed, not only is friction optimized, but the design is very simple, assembly is very straightforward, and the detent lever, because of its simple configuration, may be produced ready for installation by precision stamping~
The arrangement according to one preferred embodi-ment provides further simplification since only one end of the detent mounting pins is secured in the control housing and since lateral guidance of the detent lever is effected in simple fashion, there is no need to provide a slot ~or this guidance in the control housing.
The arrangement according to a further preferred embodiment not only reduces the friction still further, but also makes it possible to simplify the locking ring and the attachment thereof. With the arrangement of at least two detent levers facing each other, the rotating shaEt bearings, as is known, are not sub~ected to reactions in overcoming the locks~ IE reversal of the operative 8~
direction of the captive spring assembly takes place in the middle of a lock in the lock ring, and if the lock is designed, as per the present invention, with two effective areas, a particularly favourable, simple and also variable solution of the detent is obtained by the arrangement, e.g. of gates 3/4 and 5/6 as in the case of a double H
shift, since the configuration of the effective areas of the lock, and also the projection on the detent lever, may be according to the effect desired.
The arrangements according to still other preferred embodiments also have advantages, particularly in connection with predetermined conditions of a gear shift.
Low friction locking spheres in a locking device are disclosed in Figures 2 and 3 of Ger~an OS 30 ~7 117.
However, friction arises in the guide and such devices are costly to produce. They are also in permanent operative connection with the locking path.
Further details of the invention are described hereinafter in conjunction with the example of embodiment illustrated in the drawings attached hereto, the details in which comprise objects of the invention. In the drawing:

Figure 3 is a longitudinal section of Figure 1 in the direction of the rotating shaft;
Figure ~ illustrates the locking ring of a double-H shiEt, ~ith the position of the detent lever projection in individual gates.
_~ _ ~L2~41 8~3 Referring in detail to the dra~ings. In Figure 1, a rotating shaft 2, having a locking ring 3 and ]ocks or stops 32, 32A is mounted in control housing 4, locking ring 3 being connected to rotating shaft
2 by a retaining pin 35. Alternatively, locking rings - indicated by thin broken lines - may be secured to rotating shaft 2 by means of Seeger circlip rings. Two first pins 5 are secured, each in a bearing boss 41 in control housing 4, at ~ angles to rotating shaft 2 and 10 at a distance therefrom. Each of these pins carries a detent lever 1 adapted to pivot about the same radially of rotating shaft 2 and facing one another projections 11 on the detent levers 1 cooperating with locks 32, 32A
or locking rings 30. Each of the detent levers 1 is urged towards the rotating shaft by a spring 6 which bears against control housing 4, and is held by a second pin 5A, which is mounted, in parallel with the first pin 5, approximately in the plane of spring and of the projection on detent lever 1, in the same way as the said first pin, in the control housing, in conjunction with an elongated hole 12, in a radially inner position 8. A gap 81 is located between locking path 31 or rotating shaft 2 and radially inner position 8 of detent lever 1.
In Figure 2, which as indicated is a cross-section of Figure 1, 41 are the bearing bosses in control housing 4 in which pins 5A are secured. Each detent lever 1 is guided by plane surface 42 of the bearing boss and by sleeve 51 slipped onto pin 5, 5A, said pins bearing against gearbox 9, either directly or, as shown, via their heads, after control housing 4 has been assembled. Springs 6 are clamped between control housing 4 and -the detent levers 1, the latter also comprising a guide 13 or a supporting surface 14 for the springs 6.

Further to Figures 1 and 2, Figure 3 shows the arrangement of detent levers 1 centrally of rotating shaft 2 with transverse pins 5, 5A which bear against gearbox 9 after control housing 4 has been assembled thereto.
Also shown is the arrangement, known per se, of holding springs 7 between rotating shaft 2 and control housing 4.
Figure 4 shows the method of opera~ion and is a diagrammatical section illustrating a locking r:ing 3 secured to a rotating shaft 2, with a representation of gates R/C, 1/2, 3/4, 5/6, 7/8 of a double-H shift, with projection 11 on detent lever I in some of the gates.
Projection 11 is held, by restriction of the pivoting motion of detent lever 1, in elongated hole 12, by pin ; 5A (Figure 1) in such a manner that a gap 81 is provided in the radial direction between the shoulder of locking path 31 and projection 11, and locks 32, 32A bear only upon effective areas 34. The holding spring assembly is directed and arranged in such manner that the axial operative direction reverses in the axial direction when projection ; 11 is in the middle of lock 32 so that, with the gear shift lever in neutral, this lever, and thus the rotating shaft, remains in the stepped down range - gates R/C, 1/2, 3/4 - without selecting force in gate 3/4, or is returned there-to, whereas in the direct range - group drive 1:1 - it remains in gate 5/6 or is returned thereto from gate 7t8.
During the selection of gates and changing of gears 3/4 to 1/2 and from 5/6 to 7/8, and vice-versa, no locking forces are present - springs 6 - are in effect and there is also no ~ric-tion, only the axially acting forces o~
the holding spring assembly.
Locking forces, from spring ~, are in eEfect \

only when ro-tating shaft 2 is displaced from gate 3/4 to gate 5/6 and vice-versa, and during movement from gate lt2 to the R/C gate. The limited pivoting motion of detent lever 1 radially inwardly takes place when spring 6 is preloaded.
Locks 32, 32A may also be on - projecting - or in rotating shaft 2, i.e. they may be an integral part thereof.
or locking rings 30. Each of the detent levers 1 is urged towards the rotating shaft by a spring 6 which bears against control housing 4, and is held by a second pin 5A, which is mounted, in parallel with the first pin 5, approximately in the plane of spring and of the projection on detent lever 1, in the same way as the said first pin, in the control housing, in conjunction with an elongated hole 12, in a radially inner position 8. A gap 81 is located between locking path 31 or rotating shaft 2 and radially inner position 8 of detent lever 1.
In Figure 2, which as indicated is a cross-section of Figure 1, 41 are the bearing bosses in control housing 4 in which pins 5A are secured. Each detent lever 1 is guided by plane surface 42 of the bearing boss and by sleeve 51 slipped onto pin 5, 5A, said pins bearing against gearbox 9, either directly or, as shown, via their heads, after control housing 4 has been assembled. Springs 6 are clamped between control housing 4 and -the detent levers 1, the latter also comprising a guide 13 or a supporting surface 14 for the springs 6.

Also shown is the arrangement, known per se, of holding springs 7 between rotating shaft 2 and control housing 4.
Figure 4 shows the method of opera~ion and is a diagrammatical section illustrating a locking r:ing 3 secured to a rotating shaft 2, with a representation of gates R/C, 1/2, 3/4, 5/6, 7/8 of a double-H shift, with projection 11 on detent lever I in some of the gates.
Projection 11 is held, by restriction of the pivoting motion of detent lever 1, in elongated hole 12, by pin ; 5A (Figure 1) in such a manner that a gap 81 is provided in the radial direction between the shoulder of locking path 31 and projection 11, and locks 32, 32A bear only upon effective areas 34. The holding spring assembly is directed and arranged in such manner that the axial operative direction reverses in the axial direction when projection ; 11 is in the middle of lock 32 so that, with the gear shift lever in neutral, this lever, and thus the rotating shaft, remains in the stepped down range - gates R/C, 1/2, 3/4 - without selecting force in gate 3/4, or is returned there-to, whereas in the direct range - group drive 1:1 - it remains in gate 5/6 or is returned thereto from gate 7t8.
During the selection of gates and changing of gears 3/4 to 1/2 and from 5/6 to 7/8, and vice-versa, no locking forces are present - springs 6 - are in effect and there is also no ~ric-tion, only the axially acting forces o~
the holding spring assembly.
Locking forces, from spring ~, are in eEfect \
