Description
J~
The invention refers to a click-stop device, in particular for a central shaft or a gearshift lever of a gear-change transmission, comprising a stopping body and spring-loaded rolling~contact body.
Vario~s types of sw;tching equipment require their switching means to be movable in more than one line of movement and to be stopped~ Thus it is necessary to provide stopping means on a central shaft or a gearshift lever of a gear-change transmission not only in the line of the selecting movement, but also in the line of the gear-changing movementO Already known stopping devices provide a means for stopping only in one line of movement, so that it would really be necessary to have -two stopping devices on a central shnft or a gearshift lever of a gear-change transmission. The friction force to be absorbed by the gearshift lever would correspond to the sum of the friction forces occurring in both separate stopping devices and would thereFore be considerable.
The invention is based on the requirement to create u stopping device which, using only a few components, provides a simple means of obtaining stopping along two Lines of movement whilst keeping the friction force created 1hereby to a minimum.
The xequirement is met by the features indicated in the characterising part of claim l.
Compared with the prior art the invention has the advantage that only one s-topping device is necessary for ensuring stopping along two lines of movement, e.g. in connection with a gear-change transmission for gear selection and gear change. In this way good efficiency can be achieved and the component requirement can be kept to a minimum~ Vue to the seall number of components there is less wear, and the manufacturing cost can be reduced. The stopping device can be used on all gear-change transmissions and is suited in particular for small transmissions, because it requires only a small amount of space, The stopping device according to the invention can also be used for other switching equipment such as electrical switches and hydraulic or pneumutic valves where the switching means have several lines of movement.
Further advantageous developments are revealed in the sub-claims~
The invention will now be explained by way of example with reference tothe drawing of which fig. 1 is a perspective view oF a click-stop device according to -the inventiGn with a contouxed stopping block, Fig. 2 is a partial view of the stopping body with a stopping contour for selection, and with a stopping ball, partially in section, fig. 3 is a section through the stopping body along a line III-III in fig~ 2 with a stopping contour for gear-changing and the stopping ball.
A stoppillg body 1 and a s-triker 3 are mounted on a cen-tral shaft 2 (fig. 1)~ ¦
The central shaft 2 is running in bearings 4, 5 and is rotatable and axially movable, as already known. The strikex 3 is provided for e~g. the operation of guide bar for bringing in the various gears in a gear-change trans~issionO
A stopping body 1 is provided with humps 6, 7, an indentation 8 and surfaces 10, 11. Together they form a contoured stopping blockO The humps 6, 7 and -the indentation 8 form a stopping contour ex-tending transversely to the axial direction of the central shaft 2 and providing the stops for the gear~change operation, In relation to the surfaces 10, 11 the humps 6, 7 are of uniform height over their entire length and nre oF a certain height in relation to the surfaces 10, 11, The humps 6, 7 follow the line of con-tour ~ '7 of the surfaces 10, 11 which form the s-topping contour for selection.
The contour of surface 10 (fig. 1) comprises points 16, 17, which represent indentations and adjacent to which are elevations. Such a raised seCtiQn is provided at point 18. The contour of surface 11 also comprises indenta-tions at the points 19, 20, with elevations adjacent to them. Such un elevation is provided at the point 21. The contours of the surfaces 10 and 11 ore identical or at least si~ilar to each otherO In figO ~ the stopping contour for selection is reveuledO ~he balls 13 provide a particularly low-friction bearing support for the stopping ball ~O A bearing part 12 is pressed aguinst the balls 13 by means of a pressure spring and thus against the stopping ball 9, whereby the latter is kept in engagement with the stopping contour~
Instead of using balls 13 -the stopping ball 9 may be supported directly by the bearing part 12 preferably made from synthetic material (not shown on the drawing).
Fig. 3 shows the stopping contour for the gear-change operation.
The stoppin0 contour for selection (fig. 1, 2) may be shaped in such a way as to provide the driver with a feel of the forces necessary so that he receives information via the selected lane on the force to be applied during selection.
The stopping contour for the gear-change operation (figO 1, 33 may be shuped in such a way that the stopping ball (g), whilst rolling off -the downward sloping flanks 22, 23, assists in the gear-change operation thus makiny it easier.
