Abstract

The invention relates to a cog joint (16) for a vehicle transmission (10) having: at least one coupling body (18); an annular control claw (22); and a friction unit (24), wherein The friction unit (24) is positively connected to the control claw (22) in the tangential direction (26) and can act axially via the control claw (22), wherein the control claw (22) is opposite to the coupling The joint body (18) is axially adjustable between the intermediate position, the synchronous position and the shift position. In the intermediate position, the control claw (22) is basically free to rotate relative to the coupling body (18). The position control claw (22) is coupled with the coupling main body (18) in the tangential direction (26) through frictional connection, and the control claw (22) and the coupling main body (18) are tangentially coupled in the shift position. Direction (26) is connected in a form-fitting manner.

Description

technical field [0001] The invention relates to a tooth joint for an automobile 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 rotat...
