Description

Shifting device for an automated manual transmission
Technical Field
The invention relates to a shifting device for an automated manual transmission, comprising: a shift and selector shaft which is arranged so as to be rotatable about its longitudinal axis for carrying out a shift selection operation and so as to be axially displaceable for carrying out a shift selection operation; a hydraulic or pneumatic gear selection actuator arranged transversely to the gear shift and gear selection shaft, the piston rod of the gear selection actuator being in adjusting connection with a rocker arranged on the gear shift and gear selection shaft at least in a rotationally fixed manner; and a hydraulic or pneumatic shift actuator, the piston rod of which is axially fixed in adjusting connection with the shift and selector shaft.
Background
A large number of manual or automated shiftable manual transmissions of countershaft design have shift and selector shafts which are mounted so as to be rotatable about their longitudinal axes for executing a shift operation and so as to be axially displaceable for executing a shift operation. During a gear selection, one of the gear forks or gear rockers of the transmission is positively coupled to the gear shift and selector shaft, and the remaining gear forks or gear rockers are decoupled from the gear shift and selector shaft. During the shifting operation, the shift sleeve is moved axially by means of a coupled shift fork or shift rocker, which engages with a shift sleeve that is mounted on the drive shaft in a rotationally fixed and axially displaceable manner, and thus engages in or engages out one of the usually two associated gear stages.
A shifting device for a manual transmission with such a shifting and selector shaft is known from DE 102013202272 a1, which is rotatable about its longitudinal axis and axially displaceable by means of a gate guide with a gate link and a plurality of shift links. A plurality of shift forks are mounted on the shift and selector shaft in an axially displaceable manner, and by rotating the shift and selector shaft, one of the shift forks can be coupled to the shift and selector shaft in a form-fitting manner. The coupling of the shift forks is effected in each case by engaging one of a plurality of radially projecting shift pins, which are arranged offset on the circumference on the shift and selector shafts, into a groove-shaped recess which is fastened to the respective shift fork or to an integrally formed shift fork sheet. In the case of a single shift fork associated with the highest forward gear and reverse gear, two shift pins are provided which are arranged offset on the circumference of the shift and selector shaft and engage in different recesses of at least one shift fork plate of the shift fork in the case of different rotational angle positions of the shift and selector shaft. In this way, the gear stages concerned are assigned to different shift gates in relation to the externally actuated shift and selector shaft, so that incorrect shifting into one of the two gear stages is prevented.
A further shifting device for a manual transmission with such a shifting and selector shaft is known from DE 102013212633 a1, which is rotatable about its longitudinal axis for carrying out a selection operation and is axially displaceable for carrying out a shifting operation. The shift and select shaft is provided with a plurality of radially projecting shift pins arranged in a staggered manner on the peripheral side. Furthermore, a locking sleeve is arranged on the shift and selector shaft in an axially fixed and rotatable manner for each shift pin, which locking sleeve has an axial slot and a locking pin, respectively, wherein the shift pins of the shift and selector shaft each extend radially through the slot of the locking sleeve. On each of the shift pins, a shift fork is guided in an axially displaceable manner on the locking sleeve. In or on each of the shift forks there is fastened a ring set comprising two shift rings with inner radial recesses, two intermediate rings and one locking ring with inner radial recesses. In the case of a specific angular positioning of the shift and selector shaft, one of the shift forks is always axially displaceable by the associated locking bolt engaging in a recess of its locking ring and the associated selector pin engaging in one of its two shift rings, while the other shift forks are axially fixed by the associated locking bolt engaging in their locking ring and by the associated selector pin engaging in one of their recesses of their shift rings.
DE 102020103143.2, which was not published beforehand by the applicant, describes a shift module for an automated group transmission, which comprises a multi-stage main transmission, a two-stage group of half gears upstream of the main transmission, and a two-stage group of multiple gears downstream of the main transmission. On the inner side of the shifting module facing the housing of the group transmission, three shifting actuators and one selector actuator are arranged, which are designed as pneumatically actuable piston-cylinder mechanisms. The shift actuator assigned to the main transmission is arranged coaxially and axially adjacent to a shift and selector shaft of the main transmission, which can be rotated about its longitudinal axis for carrying out a shifting operation and can be moved axially for carrying out a shifting operation. The piston rod of the shift actuator is connected to the shift and selector shaft in a form-locking, axially fixed and rotationally fixed manner by means of a plug connection. The selector actuator assigned to the main transmission is arranged transversely to the shift actuator and has a U-shaped receptacle on its piston rod oriented transversely to its longitudinal axis, into which a rocker secured axially and rotationally fixed to the piston rod of the shift actuator engages. The gear shift and selector shaft of the main transmission is thus rotated by the axial displacement of its piston rod when the selector actuator is actuated, which corresponds to a gear selection process in the main transmission. When the shift actuator is actuated, the shift and selector shaft of the main transmission is also moved axially by the axial displacement of its piston rod, which corresponds to a shifting operation in the main transmission. Due to the axial sequential arrangement of the selector and selector shafts of the main transmission and the associated shift actuators in succession in stages, the shifting device, which is composed of the selector and selector shafts of the main transmission and the shift modules, takes up an undesirably large amount of installation space at least in the axial direction. Furthermore, the U-shaped receptacle arranged on the piston rod of the gear selector actuator has a relatively high mass which limits the gear selector power that can be achieved.
Disclosure of Invention
The object of the present invention is therefore to propose a shifting device for an automated manual transmission of the type described above, which has a simple and compact design and achieves high selection and shifting dynamics with a low mass of the movable parts.
This object is achieved by a shifting device for an automated manual transmission having the features of claim 1, having a special coupling of a piston rod of a selector actuator to a shift and selector shaft. Advantageous developments are defined in the dependent claims.
The invention therefore relates to a shifting device for an automated manual transmission, comprising: a shift and selection shaft which is arranged so as to be rotatable about its longitudinal axis for carrying out a gear selection operation and so as to be axially displaceable for carrying out a gear selection operation; a hydraulic or pneumatic gear selection actuator arranged transversely to the gear shift and gear selection shaft, the piston rod of the gear selection actuator being in adjusting connection with a rocker arranged on the gear shift and gear selection shaft at least in a rotationally fixed manner; and a hydraulic or pneumatic shift actuator, the piston rod of which is axially fixed in adjusting connection with the shift and selector shaft.
In order to solve the stated problem, it is provided in the shifting device that the rocker has a radially projecting crosspiece on its outer circumference, and the crosspiece of the rocker engages in a crosspiece formed on the piston rod of the gear selection actuator.
The arrangement of the gear selection actuator transversely to the gear shifting and gear selection shafts can be realized as follows: the shifting and selector shaft can be rotated about its longitudinal axis by means of an axial displacement of a piston rod of the selector actuator. One of the plurality of gear selection positions can thus be set. In particular, it is preferred that the gear selection actuator is arranged perpendicular to the shift and gear selection shaft. By forming or fastening radially projecting cross webs on the outer circumference of the rocker of the shift and selector shaft and forming cross grooves in the piston rod of the selector actuator, a coupling connection can also be realized between the piston rod of the selector actuator and the shift and selector shaft, which coupling connection can be produced in a structurally very simple and cost-effective manner.
According to an advantageous further development of the subject matter of the invention, it is provided that the transverse groove in the piston rod of the gear selection actuator is configured as a depression. The recess can be produced cost-effectively by means of a milling process. Since no separate coupling element is fastened to the piston rod of the gear selection actuator, but rather the coupling element is produced by the recess mentioned, the component to be moved for carrying out the gear selection process advantageously has a low mass. Thereby contributing to high gear selection power.
A further development of the invention consists in that the rocker on the shift and selector shaft is also connected in an axially fixed manner to it. This makes it possible for the rocker, which is fastened to the shift and selector shaft, to be moved axially together with its crosspiece when the shift and selector shaft is moved axially. In this case, it is provided that the transverse webs of the rocker have such a length that they are guided in the transverse grooves of the piston rod of the gear selection actuator over the entire axial adjustment range of the shift and selection shaft. This makes it possible to achieve with simple means that the transverse webs cannot be pulled out of the transverse grooves.
In order to simplify the assembly work, the shift and selector shaft, the shift actuator and the shift actuator can be combined in a design in a pre-assembled shift module. The shifting module is placed on an opening in the upper region of the transmission housing in the usual manner and is screwed to the transmission housing. Such shifting modules are also assigned shift forks, provided that they are arranged on the shift and selector shaft in an axially displaceable manner. The shift rocker is assigned to the manual transmission, and is usually mounted in a pivotable manner in a transmission housing of the manual transmission.

FIG. 2 shows a perspective top view of a shifting device according to the invention;
fig. 3 shows a first embodiment of a push rod of the shifting device according to fig. 1 in a partially sectioned, perspective partial view; and

Detailed description of the preferred embodiments
The shifting device 2 shown in fig. 1 and 2 is used for shifting and selecting gears of a multi-stage automated transmission, not shown in detail. The gear shifting device 2 has a gear shift and selection shaft 4, a gear selection actuator 6 and a gear shift actuator 8.
For carrying out a gear selection operation, the shift and selection shaft 4 can be rotated about its longitudinal axis in accordance with the direction of rotation arrow 10 and can be moved axially in both axial directions in accordance with the direction symbol 12 for carrying out a gear selection operation. Two shift forks 14, 16 are mounted in an axially displaceable manner on the shift and selector shaft 4, which are each engaged in an associated shift sleeve, which is arranged in a known manner on a transmission shaft of the manual transmission. The shift sleeves and the drive shafts of the transmission are not shown.
By rotating the shift and selection shaft 4 into a specific rotational angle position corresponding to the rotational direction arrow 10, one of the two shift forks 14, 16 is positively connected to the shift and selection shaft 4 by means of a coupling element that is not visible, which corresponds to a gear selection operation. By rotating the shift and selector shaft 4 to a specific axial position corresponding to the direction symbol 12, the shift sleeve engaged with the coupled shift forks 14, 16 is moved axially and thus engages or engages one of the usually two associated gear stages, which corresponds to the shifting operation. The gear selector 6 is designed as a hydraulic or pneumatic piston-cylinder mechanism and is arranged here perpendicular to the axial orientation of the shift and gear selector shaft 4.
The piston rod 28 of the gear selection actuator 6 is in adjusting connection with a rocker 18, which is arranged in a rotationally fixed and axially fixed manner on the shift and gear selection shaft 4. For this purpose, the rocker 18 has a radially projecting crosspiece 20 on its outer circumference, which crosspiece engages in a crosspiece 30 of a piston rod 28 of the gear selection actuator 6. The transverse groove 30 is currently configured as a recess in the piston rod 28 of the gear selector actuator 6 and is produced by milling. The crosspiece 20 of the rocker 18 has a length L such that it is guided in a transverse groove 30 of a piston rod 28 of the gear selection actuator 6 over the entire axial adjustment range of the shift and selection shaft 4.
When the gear selection actuator 6 is actuated, the shift and selection shaft 4 is rotated about its longitudinal axis in accordance with the direction of rotation arrow 10 by an axial displacement of its piston rod 28 in accordance with the direction arrow 32 via the adjusting connection between the transverse groove 30 and the transverse web 20 of the rocker 18, which corresponds to the gear selection process. Three latching recesses 34 of a latching device, not shown in detail, can also be seen on the piston rod 28 of the selector actuator 6.
The shift actuator 8 is designed as a hydraulic or pneumatic piston-cylinder mechanism and is arranged parallel and directly adjacent to the axis of the shift and selection shaft 4. The piston rod 36 of the shift actuator 8 is axially fixed in an adjusting connection with the shift and selector shaft 4 by means of a thrust rod 38 which is axially fixed and secured in a rotationally fixed manner to the piston rod 36 and is oriented as radially as possible.
According to a first embodiment of the tappet 38, which is shown in the partially cut-away partial views in fig. 1 and 3, it has a disk-shaped guide element 40 on its free end, which is guided in an axially fixed, radially movable and pivotable manner in the lever arm 22 of the rocker 18. For this purpose, the lever arms 22 of the rocker 18 are oriented as radially as possible in the direction of the piston rod 36 of the shift actuator 8. Furthermore, the lever arm 22 has a pocket-like or bag-like cavity 23 with an opening 24 into which the push rod 38 is pivotably inserted with a guide element 40.
When the shift actuator 8 is actuated, the shift and selector shaft 4 is also moved axially in accordance with the direction symbol 12 by an axial displacement of its piston rod 36 in accordance with the direction symbol 42 via the actuating connection between the push rod 38 and the rocker 18, which corresponds to a shifting operation. When the shift and selection shaft 4 is rotated in accordance with the direction of rotation arrow 10 as a result of a gear selection process, the piston rod 36 of the shift actuator 8 is rotated in the opposite direction in accordance with the direction of rotation arrow 44 relative to the rotation of the shift and selection shaft by means of the adjusting connection between the rocker 18 and the push rod 38.
According to a second embodiment of the tappet 46, which is shown only in the partially cut-away partial view of fig. 4, it has a fork-like coupling element 48 at its free end, which engages in an axially fixed and pivotable manner in an outer annular groove 26 of the shift and selector shaft 4. In this embodiment of the push rod 44, the shift and selection shaft 4 is moved axially in accordance with the direction symbol 12 via the adjusting connection between the push rod 46 and the annular groove 26 by an axial movement of its piston rod 36 in accordance with the direction symbol 42 when the shift actuator 8 is actuated, which corresponds to a shifting operation. However, when the shift and selector shaft 4 is rotated corresponding to the direction of rotation arrow 10 as a result of a gear selection process, the piston rod 36 of the shift actuator 8 is not rotated in this embodiment of the push rod 46.
In order to simplify the assembly work, the shift and selector shaft 4, the shift actuator 6 and the shift actuator 8 are combined in a structural manner in the pre-assemblable shift module 50.
