Embodiment Construction

[0038] figure 1 A schematic perspective cross-sectional illustration of a transmission component 1 with a shifting clutch according to one embodiment is shown.

[0039] figure 1 A shaft 2 is shown, on which a guide sleeve 3 is fastened in a rotationally fixed and axially immovable manner by means of toothing. In addition to the guide sleeve 3 , on both sides of the shaft 2 are rotatably mounted gear wheels 4 , 5 , which have axial extensions 6 , 7 on the side facing the guide sleeve 3 , on the axial extensions 6 , 7 A clutch main body 8, 9 is installed respectively. The clutch bodies 8 , 9 engage the external toothings on the extensions 6 , 7 via the internal toothing, so that the clutch bodies are connected in a rotationally fixed manner to the gearwheels 4 , 5 assigned to them. The clutch bodies 8 , 9 also have conical surfaces 10 , 11 respectively, which constitute cooperating conical surfaces for the synchronizer rings 12 , 13 , respectively. The clutch bodies 8 , 9 al...

Abstract

A clutch sleeve is provided for a shift clutch having a synchronizing device, which includes, but is not limited to a clutch body (8,9), which is connected in a rotationally-fixed manner to gear wheels (4,5) mounted so it is rotatable on a shaft (2) and has coupling teeth (30) and a friction cone as well as synchronizing rings (12,13) having a counter cone and blocking teeth (28), and which has shift teeth (31,32), the clutch sleeve (16) having shift teeth (31,32), which are designed in such a manner that a first group of the shift teeth (27) cooperates with the blocking teeth (28) until a synchronized speed is reached and a second group of the shift teeth (29) engages in the coupling teeth (30) after the synchronized speed is reached.

Description

technical field [0001] The invention relates to a clutch for a shifting clutch and a shifting clutch, in particular for a shifting transmission of a motor vehicle, by means of which clutch and shifting clutch the shifting quality can be improved. Background technique [0002] The gearshift clutch with synchronizer comprises a clutch body which is connected in a rotationally fixed manner to a gearwheel mounted rotatably on a shaft and has connecting teeth and friction cone surfaces. The shifting clutch also has a synchronizing ring with counter-conical surfaces and locking teeth, and a clutch sleeve with toothing, at least some of which cooperate with stop surfaces on the locking teeth via inclined surfaces on the front side. The sleeve is guided axially displaceably on a sleeve guide, which is connected to the shaft in a rotationally fixed manner. [0003] In shifting transmissions in which the gears are shifted when the tractive force is interrupted, ie the input shaft is ...
