- a manual transmission for a motor vehicle with a switching shaft, by the rotation of which the gears are successively preselected and can be switched by the longitudinal displacement, is known from EP-B-530466.
- a locked with the shift shaft in its longitudinal direction locking element is provided, with which the non-shifting gears are lockable, wherein the locking element is a parallel to the shift shaft mounted locking shaft and wherein for transmitting the rotational movement of a drive pin of the shift shaft in a slotted guide of the locking shaft is longitudinally guided.
- the shift shaft has shift sleeves, on which fork sleeves are rotatably mounted, on which the engaging in Synchronisierkupplitch the gears shift forks are arranged, wherein for switching the gears radially projecting claws of the shift sleeves bear against the end faces of the fork sleeve and engage the claws in ring recesses of the non-actuated fork sleeves.
- a locking device for a motor vehicle manual transmission which is designed so that it already in the selection of the shift gate, i. before in the selected shift gate the gear to be switched is engaged, the non-switching switching elements locked , is known from DE-A-199 51 683 of the Applicant.
- This manual transmission has a central switching shaft with fork-shaped switching elements in the form of shift rockers or shift forks, which engage in sliding sleeves, and a locking device having a lever whose pivot point is located on the axis of rotation of the axially displaceably mounted central shift shaft and the via a radial entrainment with you are connected.
- a locking member which is fixed to the housing in the switching direction and which has a coupling drive, which converts the rotation of the lever in a linear movement of the locking member transverse to the switching direction of the central switching shaft.
- locking elements on the switching elements and the locking part which are designed such that when overlapping these locking elements in the switching direction, a switching movement of the switching elements is prevented.
- the blocking part is in particular a blocking plate, which is displaceably mounted on a plurality of guide bolts transversely to the central switching shaft and which is provided with a multiplicity of recesses which interact with blocking elements arranged on the switching elements.
- This known locking device has a longitudinally and transversely movably arranged in the transmission housing circuit board, which is provided with a plurality of differently designed openings. Each opening is penetrated by a projection which can move within the opening in two mutually perpendicular directions.
- the shell from the shift lever for the transmission interspersed.
- a lock plate is provided which is slidable relative to the shift lever in the transverse direction in the transmission housing, but is fixed in the axial direction with respect to the shift lever.
- this locking plate has a plurality of differently configured openings that are similar but not identical to the openings in the circuit board.
- the openings in the two plates perform relative movements to the projections which are arranged on the upper side of switching elements and which enforce both the openings in the locking plate and in the circuit board.
- the geometries of the openings once in the circuit board and once in the locking plate are chosen such that a longitudinal displacement of the circuit board, ie parallel to the switching shaft, leads to the movement of only a single switching element, while the other switching elements are locked.
- Object of the present invention is to provide a locking device for a motor vehicle manual transmission, with which a secure locking any number of switching elements is made possible, which has a small number of components and which is inexpensive to produce.
- the invention is therefore based on a locking device for a motor vehicle manual transmission, which has a switching shaft with switching elements, each switching element is provided with a protruding profile body, which is formed in a plate-shaped locking device Recess or groove interspersed, wherein the plate-shaped locking device extends over all switching elements and is mounted displaceably transversely to its longitudinal axis.
- the recesses are formed such that in the switched state of a switching element, the other switching elements are determined by their associated profile body in the recesses.
- each recess in the plate-shaped locking device has the shape of an elongated groove whose width corresponds to the diameter of the profile body and whose longitudinal axis extends at an angle to the longitudinal axis of the plate-shaped locking device, wherein two adjacent grooves in are formed opposite directions relative to the longitudinal axis of the plate-shaped locking device and that each groove is provided with two lateral, opposite bulges, which are formed such that the common longitudinal axis of the two bulges perpendicular to the longitudinal axis of the plate-shaped locking device.
- These grooves can also be referred to as cross grooves.
- the locking device when switching within a . Alley always displaced in the same direction; As a result, the locking path is bisected in the direction transverse to the longitudinal axis in an advantageous manner, so that the required space is reduced.
- Such a locking device is particularly suitable for replacing a limited to three switching elements conventional locking system. Due to the novel design of the plate-shaped locking device can more than three, ie 3 + n, switching elements are locked, at the same time the number of components compared to the conventional locking devices is significantly reduced.
- Fig. 1 is a plan view of a locking device according to the invention.
- Fig. 2 is a plan view of another preferred embodiment of the locking device according to the invention.
- the switching elements are movable in the longitudinal direction of the locking device.
- a recess in the plate-shaped locking device 2 is provided, wherein in the example shown in Fig. 1, each recess in the form of an elongated groove 6, 6 ', 6 “and 6'", whose width corresponds to the diameter of the profile body 5, 5 ', 5" and 5'", wherein the longitudinal axis 8, 8 ', 8" and 8'"at an angle ⁇ or ß to the longitudinal axis 10 of the plate-shaped locking device 2 extends ,
- Each elongated groove 6, 6 ', 6 "and 6'” is provided with two lateral opposing protrusions 7a, 7b, 7'a, 7'b, 7 "a, 7" b, 7 "'a and 7”' b provided, which are formed such that the common longitudinal axis 9 of the two bulges perpendicular to the longitudinal axis 10 of the plate-shaped locking device 2 extends,
- the angle ⁇ which includes the axis 8 '"of the elongated groove 6"' for the switching element V "with the longitudinal axis 10 of the plate-shaped locking device 2
- the longitudinal axis 8 'of the elongated groove 6 'for the switching element V with the longitudinal axis 10 of the plate-shaped locking device includes.
- Each switching element to be switched 1, 1 ', 1 "and 1'" moves over the associated profile part 5, 5 ', 5 "and 5'", which passes through the associated recess, in a direction transverse to the longitudinal axis 10 of the plate-shaped Locking device 2, ie in the direction of the Y-axis.
- the other switching elements are thus determined via their associated profile parts in the recesses.
- the elongated grooves of two adjacent shift gates are formed in the opposite direction sense relative to the longitudinal axis 10 of the plate-shaped member, as explained above.
- the locking device for 3 + n switching elements thus consists essentially only of the slidably displaced in the gear housing plate-shaped locking device 2, which is provided with suitably shaped recesses and preferably from the pin-shaped profile bodies 5, 5 ', 5 "and 5'", so that only one Minimum number of components for the secure locking of the switching elements 1, V, 1 "and 1 '" is required.
