Abstract: The invention relates to a shifting device for a motor vehicle transmission, comprising a first coupling component, a second coupling component rotatable about a transmission axis (A), an inner friction ring which has a conical surface on a radially outer face, an outer friction ring which has a conical surface on a radially inner face, and an intermediate friction ring which comprises a friction cone and is connected to the second coupling component for joint rotation with and for axial displacement with respect to the second coupling component, whilst the inner friction ring and the outer friction ring are connected to the first coupling component for joint rotation with and for axial displacement with respect to the first coupling component. The friction cone extends between the conical surfaces of the inner friction ring and outer friction ring, the coupling components being decoupled in the rotation direction in an axial starting position of the outer friction ring and being coupled in a frictional fit in the rotation direction in an axial frictional fit position of the outer friction ring. The intermediate friction ring has a C-shaped ring cross section extending peripherally in the circumferential direction, comprising a radially outer linear cone limb which forms the friction cone and comprises two substantially parallel conical friction surfaces, and comprising a radially inner linear axial limb which is integrally connected to the cone limb by a radial web.

Abstract: In a speed change apparatus for a vehicle, a controller stores as a clutch-disengaging shift spindle angle θ1 a position at which a clutch is disengaged when a shift spindle is rotated in a first direction. The controller controls the shift spindle by a first step W1 of rotating the shift spindle in the first direction until a disengaging-side target angle Ta1 is reached; a second step W2 of returning the shift spindle in a second direction opposite to the first direction; and a third step W3 of rotating the shift spindle in the first direction up to the clutch-disengaging shift spindle angle θ1 and thereafter rotating the shift spindle in the second direction to return the shift spindle, upon detection of an output from a drum angle sensor, the output corresponding to shallow engagement of dog teeth.
