| das
Getriebe, - |
transmission |
| schalten
[an•schalten/aus•schalten] |
to
shift (gears) [to switch on/off] |
| die
Übersetzung, -en; übersetzen |
gear
ratio, translation; to translate, transmit (power--with the implication
that there is a gear ratio involved) |
| das
Zahnrad, ¨-er |
gear |
| drehen |
to
turn |
| die
Hauptwelle, -n |
main
shaft, output shaft [the gears on this shaft spin freely on bearings until
a gear is engaged by the Schiebemuffe, which forces the shaft to turn with
that gear] |
| die
Vorgelegewelle, -n |
countershaft,
layshaft [below the Hauptwelle. This shaft is directly connected to the
input shaft from the engine. This shaft and the gears on it all spin together
as one unit; each gear on this shaft causes the corresponding gear on the
main shaft to spin, but does not cause the main shaft to rotate until the
Schiebemuffe engages one of the gears on the main shaft.] |
| der
Leerlauf |
idle,
idling, engine idling, neutral (gear position) |
| die
Synchroneinrichtung, -en |
synchronizer
[refers to the whole assembly], syncromesh mechanism |
| der
Synchronring, -e |
synchronizer
ring [sometimes just called "synchronizer." The gear is on one
side of this ring, and the Schiebemuffe and Synchronköper (synchronizer
hub) are on the other side of this ring. To put in a gear, the Schiebemuffe
pushes the synchronizer ring into contact with the gear. The conical inside
part of the synchronizer ring fits over the conical Synchronkegel/ Kupplungskörper
(synchronizer cone) on the gear, and friction between them causes their
speeds to become the same. The dog teeth on the Schiebemuffe can now smoothly
engage the teeth on the gear.] |
| der
Synchronkörper, - |
synchronizer
hub [this is connected to the Hauptwelle and always spins with it. The Schiebemuffe
slides left and right on this hub, but always remains connected with it
and thus also always spins with the Hauptwelle.] |
| der
Synchronkegel, -; der Kupplungskörper, - |
synchronizer
cone [conical protrusion located on the gear. When it comes into contact
with the conical inside part of the Synchronring, friction equalizes their
speeds, making it possible for the Schiebemuffe's dog teeth to engage with
the holes in the gear. When you hear a grinding noise when you're shifting,
you're shifting into a gear that's so wrong that this process can't work] |
| die
Schiebemuffe, -n; die Schaltmuffe, -n |
collar,
sliding sleeve, synchronizer sleeve, selector sleeve [The collar sits on
(and thus rotates with) the Synchronkörper, which rotates with the
Hauptwelle. The collar's "dog teeth" need to be fitted into the
corresponding holes in the gear wheel to engage a gear; the synchro makes
this a smooth process] |
| das
Druckstück, -e; der Synchronriegel, - |
synchronizing
key, clutch key [there are usually three of these little "keys";
the Schiebemuffe pushes the Synchronring against the Synchronköper/
Kupplungskörper on the gear by pushing on these little keys. ] |
| das
Losrad, ¨-er |
idler
gear [i.e. any gear that is spinning freely on the main shaft, not engaged
by the Schiebemuffe] |
| das
Festrad, ¨-er |
fixed
gear [i.e. a gear on the main shaft that has been engaged by the Schiebemuffe
and so is now making the main shaft spin with it] |
| die
Reibung |
friction |
| |
|
| der
Drehmomentwandler, - |
torque
converter |
| das
Leitrad, ¨-er |
stator
[at the center of the torque converter, where it reverses the direction
of the fluid flow and increases the torque at low speeds, and just "gets
out of the way" at high speeds] |
| die
Antriebswelle, -n |
drive
shaft, input shaft [in this context, the shaft coming directly from the
engine that drives the torque converter; further below, the shaft driving
the planetary transmission] |
| die
Abtriebswelle, -n |
output
shaft [in this context, this is the shaft powered by the torque converter;
further below, it's the shaft driven by the planetary transmission] |
| die
Fliehkraft, ¨-e |
centrifugal
force |
| die
Schaufel, -n |
vanes,
blades (of a turbine); shovel |

the

| [die
Lamelle, -n] |

slat; in the plural this is the name for "sipes" in a tire tread,
i.e. the little slits between the tread grooves] |
| die
Lamellenkupplung, -en |
multi-plate
clutch [used within the planetary transmission, as well as in limited-slip
differentials and 4wd vehicle power distribution systems; hydraulically
operated in this case] |
