摘要:
A shift rocker arrangement for a transmission including a two-arm bracket shift rocker that extends around a transmission element to be shifted and is supported by pivot bearings on the arms of the bracket within a transmission housing to pivot about an axis located essentially in the plane of the bracket. The shift rocker has bearing elements formed on the bracket arms and complementary bearing shells are formed on the inside wall of the closed housing. The bearing shells that support the bearing elements of the shift rocker are either formed on a bearing bar, which is supported at both ends by the housing, or they are formed directly on inside walls of the housing.

A switching mechanism of a multiple change-over gear with an axially displaceable and pivoted gearshift lever shaft having a shift finger formed on the gearshift lever shaft with switching wings which are operatively connected with a synchronization and coupling device for wheels supported on a wheel set shaft of the gearing unit, and with cams formed on the switching wings with which the shift finger can mesh for the execution of a process of gear ratio modification and, over the cams, can axially displace the switching wings.
摘要:
The invention concerns a shift rocker arrangement (2) for a shift transmission, comprising a shift rocker (4) in the form of a two-arm bracket that extends around a transmission element to be shifted, which is mounted to pivot within a transmission housing (42) about a pivot axis (6) located essentially in the plane of the bracket by means of pivot bearings arranged on the arms (14, 16) of the bracket. To avoid openings leading through the wall of the transmission housing for the insertion of pivot pins for mounting the shift rocker, it is provided that the shift rocker (4) is mounted by means of bearing elements (24) formed on the bracket arms (14, 16) and complementary bearing elements (34) provided on the inside wall of the closing housing.The transmission housing is preferably divided in the area of the bracket plane. The bearing shells (38, 40) that hold the bearing surfaces (26, 28) of the shift rocker (4) are either formed on a bearing bar (36) mounted at one end in the main housing portion (46) and at the other end in the housing cover (48), or they are formed directly on the inside wall of the main housing portion (146) and of the housing cover (148).

An oil supplying device (34, 36, 38) for a vehicle transmission (2) having one transmission housing (4, 6) with gears (10, 12, 16, 18, 22) situated upon shafts (8, 14, 20) and having teeth, bearings in which gears (10, 12, 16, 18, 22) and shafts (8, 14, 20) are rotatably mounted and one switch gear (30, 32, 50) suited to connect the gears (10, 12, 16, 18, 22) and shafts (8, 14, 20) for a transmission of torque. The device has an oil collecting duct (34) arranged on movable elements (32, 50) of the switch gear (30, 32, 50) which moves with the elements (32, 50) of the switch gear (30, 32, 50) and which extends substantially through the part in the transmission housing (4, 6) having all the gears (10, 12, 16, 18, 22). The oil collecting duct (34) has at least one opening (36, 38) which during movements of the elements (32, 50) of the switch gear (30, 32, 50) coats areas within the transmission housing (4, 6) on which the bearings and teeth are situated.
摘要:
Manual transmission, in which two separate actuating devices are assigned to the individual gearshift bodies, that is the gearshift forks and/or the gearshift rockers. A gearshift body, that is a gearshift fork and/or a gearshift rocker, can be actuated selectively by means of one or the other actuating device. The actuating devices are preferably gearshift rods.

A shift device for a change-speed gearbox, includes a shift rocker having sidewalls for axially displacing a shift sleeve positively connected to a gear wheel clutch or synchronizing unit. A shift finger is fixedly mounted on a shift shaft and positively engages a shift slot of the shift rocker to operate the shift rocker. The shift rocker is of single-piece configuration and made through a non-cutting process, with a blank being pre-punched from a steel sheet, before the blank is shaped into a finished product by at least one bending operation.

In a shifter of a manual transmission, a rotationally and axially movable shifter shaft is provided with a plurality of coupling members that are immovable with respect to it. The members are staggered with respect to one another both axially and in the circumferential direction. A shift fork is used for actuation through a counter-coupling member associated with the fork.

A shifting arrangement for a synchronized motor vehicle transmission with six forward gears and one reverse gear has a longitudinally displaceably and rotatably disposed shifting shaft whose shift fingers can be introduced into mutually aligned grooves of shift tongues for the preselecting of the transmission gears. The shift tongues are pivotally connected to swinging forks which are pivotally arranged in the transmission case and, via their forks, engage in a formlocking manner in sliding sleeves of synchronizer clutches. The shifting fork of the reverse gear is fastened on a shift rod situated perpendicularly to the shifting shaft on which a guide rail is constructed for the longitudinal guiding of the shift tongues.
摘要:
A shifting apparatus for a manual transmission able to shift two shift stages, of which selection positions are different but shift positions are the same, using a single fork and a single sleeve. Compared to the related art in which a fork and a synchronization sleeve are provided to each of two independent shift stages, the full length of the transmission is reduced, thereby reducing the weight and manufacturing costs.
