Embodiment Construction

[0029] Figure 1 to Figure 9 It relates to a vehicle transmission 10, in particular a dual-clutch transmission or an automatic transmission, having: a transmission shaft 12 rotatable about a transmission axis A, two rotatable on the transmission shaft 12 and (except limited by production conditions and for driven Outside the desired bearing clearance for the safety function) the driven wheel 14 is supported axially immovably, and the cogging engagement 16. In this case, the driven wheels 14 of the motor vehicle transmission 10 are each fixedly connected, in particular constructed in one piece or welded, to the coupling body 18 of the dog joint 16 . according to Figure 2 to Figure 4 On the (left) side of the dog engagement 16 facing the smaller output wheel 14 , there is provided a separate clutch output plate 19 belonging to the coupling body 18 , which is firmly pressed in with the output wheel 14 .

[0030] The dog joint 16 for the vehicle transmission 10 comprises: two c...

Abstract

The invention relates to a dog clutch (16) for a vehicle transmission (10). The dog clutch comprises at least one coupling body (18) fixed to a gear wheel (14) of the vehicle transmission (10) and on one of a transmission axis (A) rotatable transmission shaft ( 12) mounted rotatably and axially non-displaceable substantially, a hub (20) on the around the transmission axis (A) rotatable transmission shaft (12) rotationally fixed substantially, and is axially displaceably mounted, and an axially displaceable switching element (22) in the axial direction (24) is connected to the hub (20) and clamped axially and in the circumferential direction (26) with the hub (20) forms a frictional connection, wherein the switching element (22) and the hub (20) relative to the coupling body (18) axially between a neutral position, a synchronization position and a switching position can be adjusted, wherein the coupling body (18) is substantially rotated freely in the neutral position both relative to the switching element (22) and relative to the hub (20), in which synchronization position is positively connected to the switching element (22) in the circumferential direction (26) and coupled via the frictional engagement with the hub (20), and in the switching position, both the switching element (22) and with the hub (20) in the circumferential direction (26 ) is positively connected.

Description

technical field [0001] The invention relates to a tooth joint for a vehicle transmission. Background technique [0002] Claw joints for motor vehicle transmissions are generally known in the prior art and are distinguished by their structurally simple and thus inexpensive construction. However, particularly in the case of high rotational speed differences and / or high moments of inertia of the components to be coupled, the dog engagement has low shift comfort and undesirably high noise generation and component loading. Contents of the invention [0003] The object of the present invention is to provide a dog engagement for a motor vehicle transmission which allows a low-noise and low-wear shifting operation with high shifting comfort. [0004] According to the invention, this object is achieved by a dog joint for a motor vehicle transmission, which has at least one coupling body, which is fastened to a driven wheel of the motor vehicle transmission and is mounted rotatably...
