摘要:
A transmission according to an embodiment includes a shift fork swingably supported by a case to move a movable element in an axial direction in accordance with the motion of a second shaft to two shift positions; two first protrusions provided on the second shaft and spaced apart from each other in the axial direction; and a second protrusion provided on the shift fork, and when the second shaft is in one of select positions, is positioned between the two first protrusions and overlaps with the first protrusions viewed from the axial direction. A protruding direction of the first protrusions and a protruding direction of the second protrusion are orthogonal to a swinging center of the shift fork when viewed in the axial direction. The second protrusion protrudes from the shift fork toward the swinging center. The second shaft is positioned between the second protrusion and the swinging center.

A dual shift fork includes a sliding fork and a rotary fork rotatably connected to the sliding fork. A pair of pad members are disposed on an inner side of both ends of the sliding fork. A sleeve disposed at an inner side of the sliding fork and contacting the pad members. The pad members are simultaneously engaged with the sliding fork and the rotary fork at an inner side of both ends of the rotary fork. The rotary fork rotates at a predetermined angle with respect to the sliding fork as the sleeve moves independently from the sliding fork.

A shifting device for a manual transmission having a shift rocker formed by two rocker arms connected by a rocker bridge, which is arranged over a shift sleeve via two slide-blocks attached to a holder at the end of each rocker arm, which pivots about a transverse axis defined by bearing points. A carrier element is positioned off-center on the rocker bridge to engage with a shifting pin of a shifting shaft. The rocker arm closer to the carrier element has a lower elastic rigidity than the other rocker arm. To produce different spring rigidities, the rocker arm closer to the carrier element has the geometrical form of a spring element which is elastic in the pivoting direction. The, rocker arm farther away from the carrier element is a bracket with relatively greater elastic rigidity.

A shifting device (1) for shifting a motor vehicle transmission with a shift selector shaft on which a plurality of shift elements (2) such as shift forks or shift rockers (3) are arranged and can be displaced to carry out a shifting operation. The shifting device (1) includes one hydraulic shift cylinder (5, 11, 18, 25), that can be actuated from both sides, with a piston (9, 15, 16, 19, 26) that can be displaced within a cylinder housing (6) and which is actively connected with a shift element (2) to be actuated. To simplify a shifting device (1) of this type, the piston (9, 15, 16, 19, 26) has a piston rod (10, 17, 23, 29) that follows the movement of the piston (9, 15, 16, 19, 26) and can be connected directly to the shift element (2) in a detachable manner.

A shifting rocker (2) for a transmission comprises two arms (4, 6), between which a mount for a sliding sleeve is provided. The shifting rocker (2) is mounted in a transmission housing at two bearing points (20, 22) such that it can pivot. Further, a lever arm (16) is positioned on the shifting rocker (2), via which force is applied to the shifting rocker (2) for the purpose of pivoting the shifting rocker (2) about the bearing points (20, 22). The lever arm (16) is positioned on the shifting rocker (2) in the area (24) between the two bearing points (20, 22).
摘要:
A gear shift mechanism has a displacement device, which can be operated by an actuator, for the axial displacing of a sliding sleeve. The actuator is connected with the displacement device by way of at least one joint. Such an articulated connection between the actuator and the displacement device permits a greater freedom with respect to the spatial arrangement of the actuator and thus a very compact construction.

The invention relates to a gear shifting device (2) comprising a single-rod gear shifting system in a housing of a motor vehicle manual gearbox. Said device comprises a central gearshift shaft (32) and fork-type gear shifting elements in the form of gear shifting swinging forks or gear shifting forks (4, 6, 8, 10) which are optionally and individually engaged with the gearshift shaft (32) by rotating the same (32), and which carry out a gear shift of the selected gear shifting element by means of displacement of the gearshift shaft (32) along a rotational axis (34) of said gearshift shaft (32). Said gear shifting device (2) comprises a first element (58, 60) which is connected to the gearshift shaft (32) and which co-operates with a second element (62) fixed in the housing, in order to define the rotation of the gearshift shaft (32). The second element (32) fixed in the housing comprises a number of slits (66) of a defined width, corresponding to the number of gear shifting passages, said slits co-operating with two pins (58, 60) which are arranged on the gearshift shaft (32) and which form the first element. Each one of said pins (58, 60) engages in the slit (66) corresponding to the respective gear shifting passage during the rotation of the gearshift shaft (32), when one of the gear steps is positioned in the selected gear shifting passage.
