Background of the invention

at Motor vehicles with manual transmissions the driver unconsciously expects the selector or shift operations a haptic feedback from the shift lever giving it indicates which selector lever the gear lever is currently in is located or which gear is engaged. For example, it is common that the shift lever after its release without engaged gear automatically in the selector gate between the 3rd and 4th gear is moved back, so that a certain dialing or operating force must overcome to the Shift lever in the shift gate for the 1st and 2nd gear to bring. Almost inevitable is that the driver at Select the reverse aisle alley or Turn in reverse a haptic feedback receives. This feedback is usually designed as a noticeably higher actuation force, so that the driver clearly senses that he is about to to engage the reverse gear.

The publication DE 101 53 926 A1 describes a device for generating switching forces. The device has a pivotable about its pivot axis and along its pivot axis slidably mounted switching shaft which carries a pivoting lever during a pivoting movement, which acts with the interposition of a rocker arm on an elastic spring element. By actuating the elastic spring element, an additional switching force or switching counterforce is generated, which the driver perceives as haptic feedback.

The publication DE 100 59 376 A1 describes a selection and switching device of a transmission for selecting between at least two shift gates, which shows a switching shaft in the region of the switching dome, which actuates an elastic spring device in a pivoting movement via a arranged on the switching shaft pivot arm via a second lever, which similar to that in the previously described document is formed.

Probably the closest prior art is the document GB 2 037 916 A , which proposes a device in a gear selector mechanism for a manual vehicle transmission. Starting from the manual shift lever, the selector or shift force is transmitted via a joint to a selector shaft, which is mounted pivotably about its own axis and displaceable along its own axis. During pivoting movements of the selector shaft, a fixed contact with the selector shaft is entrained, which is actuated by the pivoting movement of two radially arranged to the selector shaft elastic spring devices and signals in this way a switching or selection force. The mechanism for generating the switching force is arranged in the gear train after the manual shift lever, but before and in particular outside of the transmission.

Detailed description the drawings

The 1 shows in a schematic, three-dimensional representation of a shock barrier module 1 , which is designed to generate an actuating force, in particular a selection or switching force in a selection or switching operation. The impact lock module 1 has a module housing 2 on which in 1 is formed rectangular or cuboid in the lower region and in the upper region in a top plan view from the front semi-circular shaped head portion 3 having. On the front side shows the module housing 2 a lid 4 on which in the in 1 lower section also right ckig and semicircular in the upper section is formed.

In the area of the head section 3 has the impact lock module 1 a continuous recording 5 for a transmission shaft (not shown), which in the impact lock module 1 pivotally mounted about its own longitudinal axis, but in the axial direction in the impact lock module 1 is fixed. The transmission shaft, not shown, by means of a selector lever 6 operated, in particular pivoted, wherein the selector lever 6 has two substantially perpendicular to each other arranged, free legs, each comprising a through hole for receiving a bolt or the like at its free end.

When installed in a vehicle is the selector lever 6 operatively connected to a manual shift lever operated by the driver to select and / or shift a gear. The transmission shaft, not shown, is in operative connection, in particular via a joint, connected to a central control shaft, wherein the central control shaft is mounted axially displaceable and pivotable relative to its own longitudinal extent.

The impact lock module 1 serves on the one hand to transmit a selection movement for selecting the reverse gear to the central control shaft and thus to the transmission and on the other hand to generate an additional operating force, in particular selection force that the driver perceives as a haptic feedback as soon as the manual shift lever by the driver in the reverse aisle to be led. The generation of the actuating or selection force will be explained with reference to the following figures.

The 2 shows the impact lock module 1 in 1 with the lid open 4 , where a shock lock lever 7 can be seen, which at a pivoting about the defined by the transmission shaft not shown pivot axis in a clockwise direction over the with a running contour 8th equipped top of a piston 9 running. The piston 9 is - as will be explained below - yielding and / or resiliently mounted in the axial direction, so that this during the pivoting of the impact lock lever 7 clockwise in 2 is moved down.

The 3 shows the impact lock module 1 with graphically suppressed module housing 2 in a schematic representation of the page. From the illustration it can be seen that when pivoting the impact lock lever 7 about the pivot axis of the transfer shaft, not shown, the free end of the impact lock lever 7 the running contour 8th of the piston 9 leaves, which via a spring 10 resilient in the axial direction with respect to a lower part 11 is stored, and this presses against the spring force down. The direction of actuation of the piston 9 , the feather 10 and the lower part 11 comprehensive actuator is oriented radially to the pivot axis and / or cuts in imaginary extension of the pivot axis and is oriented radially outward.

Based on 4 which is a schematic side view of the impact lock module 1 with suppressed module housing 2 shows, the operation of the impact lock module 1 explained. By pivoting the selector lever 6 (in 4 not shown) is a drive plate 12 , which is non-rotatably coupled to the transmission shaft, not shown, pivoted about a pivot angle.

The driving disc 12 is formed as a flat disc with a central through hole and has a circumferentially extending radially outer side recess, in which a on the impact lock lever 7 arranged driving pin 13 intervenes. At a pivoting of the transmission shaft and thus the drive plate 12 in 4 counterclockwise, the drive plate runs 12 initially free until the driving pin 13 the end of the radial recess of the drive plate 12 has reached and the otherwise freely pivoting shock lock lever 7 from the drive disc 12 over the driving pin 13 is taken. In a further pivoting of the transmission shaft, thus the drive plate 12 and over the driving pin 13 the strike lock lever 7 is the free end to which an impeller 14 is arranged so moved that the impeller 14 the running contour 8th of the piston 9 along and due to the surface shape of the running contour 8th the piston 9 against the spring force of the spring 10 in the direction of the lower part 11 suppressed. The roller 14 is on an axis, in particular a bolt or the like, rotatable with the impact lock lever 7 connected. The driver, who has triggered this pivoting movement via the manual shift lever, perceives this resilient resistance as actuation or selection force and is thereby advised that he has pushed the manual shift lever into the reverse gear alley.

The 5 finally shows the impact lock module 1 in a schematic three-dimensional representation with suppressed module housing 2 from another angle, recognizing that the drive plate 12 and the strike lock lever 7 on both sides of a bearing 15 is included, which is the transmission shaft, not shown, with respect to the module housing 2 support. In addition, it can be seen again from this illustration that impact lock lever 7 , Selector lever 6 and drive disc 12 to pivot about a common pivot axis.

The advantage of the impact lock module shown 1 lies in particular in the fact that the shock lock lever 7 is pivotally mounted on the transmission shaft and only on the drive plate 7 is taken. As a result, the entire assembly can be realized very space-saving, since the impact lock lever 7 during normal operation in the forward gears is not pivoted. In modified embodiments, the running contour 8th on the strike lock lever 7 be arranged and the operating end of the piston 9 instead be equipped with a roller or a sliding contour. By dispensing with the advantages of the space-saving design, the drive plate 12 omitted and the shock lock lever 7 be attached rotatably directly on the transmission shaft. In other embodiments, the impact lock module is not between the bearings 15 but left or right of it.

The 6 shows a schematic block diagram of a gear train 16 to illustrate a possible integration situation of the impact lock module 1 , The gear train 16 includes an external circuit 17 and an inside circuit 18 , Which via a pivotally mounted and axially displaceable central control shaft 19 coupled together. The external circuit 17 has a manual shift lever 20 and at least one of the impact lock modules 1 on, the inside circuit 17 includes the gearbox 21 and a gear dom 22 ,
